See the training materials and job aids for more Information. RRD is accessed through EUP. The RRD application displays specific tax return and status information for tax returns/extensions processed by the MeF application. This application allows IRS employees to view 100% of the data transmitted on MeF tax returns/extensions (including attachments) in a format that resembles paper forms. Use Document 6209, IRS Processing Codes and Information, 1040 attachment guide, Tax Form and Instructions (accessible through the IRS Home Page), and Pub 17, Your Federal Income Tax (For Individuals), when processing amended returns. These are valuable resources for obtaining additional information, resolving questions and completing math verification. This IRM doesn't cover all scenarios. See your lead or manager when clarification is needed.

# General Amended Return Processing

3.11.6.2 (07-10-2025) General Amended Return Processing The operational instructions in this IRM determine if the adjustment request can be made in SP or if it must be sent to another area or function. Not all scenarios are covered by this IRM. Follow IRM 3.11.6.1.7, Related Resources, when this occurs. If clarification is needed, contact your lead for assistance. General SERP Alerts issued for IRM 3.11.6 are additions to the IRM and are followed as part of IRM 3.11.6. The operational guidance in this IRM takes precedence over any conflicting IRM. The specific section instructions take precedence over any general instruction. Note: This IRM does link to specific subsections in other IRMs. When following links to other subsections, typically, the instructions are within that subsection. Occasionally, there are instances in which you must follow a link within the subsection. Example: When researching CTC to determine eligibility, you refer to IRM 21.6.3.4.1.24.1, Child Tax Credit (CTC) - Qualifications. If the eligibility criteria are met, you continue processing the claim per IRM 3.11.6. If eligibility isn't met and you're instructed to disallow, you refer to IRM 3.11.6.15.2.2.6, Child Tax Credit (CTC), and IRM 3.11.6.11.5, Correspondence for Disallowing a Claim (Letter 105C, Letter 105SP, Letter 106C, and Letter 106SP), for instructions on disallowing the claim. Use of IAT tools is required. IRM instructions take precedence over any instructions, directions or default inputs the IAT tools provide. If specific IRM instructions are not present, accept the IAT Tool results. Note: Prior to using the IAT tools, you must setup and complete your IAT profile. All references to line numbers are for the current revision of the form or schedule unless otherwise specified. Researching previous tax years may assist in processing a return. Tax examiners must have a valid business reason to access related accounts. When researching previous tax years, use CC IMFOL instead of CC MFREQ when an account isn't on the Taxpayer Information File (TIF). When processing an amended return, the CII Case ID is required in the remarks section of all IDRS transactions, such as REQ54, ENREQ, REQ77, and credit transfers.

# IAT Tools

3.11.6.2.6.2 (06-24-2025) IAT Tools The use of IAT Tools is required by all SP 1040-X employees. IAT tools are desktop productivity enhancing tools and simplify taxpayer account processing by assisting the user with IDRS research and input. If IDRS or a CC is down or not functioning properly, IAT won't function correctly. If you're having a problem with an IAT tool, try entering the CC manually using IDRS. If there are no IDRS or CC issues, continue processing the case manually and notify your lead or manager there's a problem with IAT. If an IAT tool isn't available, or an employee has a problem with the IAT Tool Manager, the case must be processed through IDRS following established procedures. Caution: IRM instructions take precedence over any instructions, directions or default inputs the IAT tools provide. If specific IRM instructions are not present, accept the IAT Tool results. The IAT tools used are: Note: The following link to the Integrated Automation Technologies (IAT) Tool Job Aids, has information specific to each tool and the IDRS command codes needed for each tool.

# Controlling Cases on the CII System

3.11.6.3 (01-02-2024) Controlling Cases on the CII System All SP 1040-X inventories, received on paper and scanned into the CII system, received through the Modernized e-File (MeF) system, or the DUT are held in a generic central CII queue. The central queue is commonly referred to as the Global Queue (GQ) and can be identified by the unique IDRS number, 0938000000. Each case in the GQ is controlled systemically on the IDRS when the CII case is created. Cases in the GQ are considered unassigned (UA) and pending assignment through auto-distribution. For more information on controlling CII cases or auto-distribution, see IRM 3.13.6.2.7, Preparing Documents for Scanning - General Instructions, IRM 3.13.6-1, APPENDIX A - DOCUMENT TYPES, CATEGORY CODES, IMF DOMESTIC, and IRM 3.11.6.3.1, Auto-Distribution. If any part of the CII case data is incorrect, follow to IRM 3.11.6.5.8, Updating Case Data, before completing your case action. If the case has multiple control bases with the same received date, close all bases upon case completion. If you receive an inquiry from another area concerning controlled cases, the inquiry must be on Form 4442, Inquiry Referral, or E-4442. Refer to IRM 3.11.6.17.9, Form 4442 and E-4442, Inquiry Referrals.

# Auto-Distribution

3.11.6.3.1 (08-16-2023) Auto-Distribution The CII system's auto-distribution functionality is used in SP to distribute cases to a SP 1040-X tax examiner (TE) for processing. Cases are distributed during the evening, Monday through Friday, based on the TE's CII profile. It's the responsibility of the TE's manager to set and adjust the TE's CII profile settings: Availability (AVBL) Max User Inventory limit (MUI) Volume per Day limit (VpD) Skill Set The AVBL setting must be set to "Available" for a TE to receive cases through auto-distribution. Using the "Unavailable" setting prevents the system from auto-distributing cases to the TE, and cases can't be manually assigned to or reassigned from the TE. The Unavailable setting must only be used when a TE is detailed to another area or is placed in non-duty status. Caution: If changing a TE's Availability to "Unavailable" , all cases, if any, in the TE's inventory must be reassigned manually by the manager to another TE before making the profile change. The MUI limit is 500 cases. This limit is the total number of cases a TE can have in inventory and cases in suspense count against this limit. If a TE's inventory reaches the limit, the TE is excluded from distribution until the TE's inventory falls below the limit. Cases that are created using TE's number in CII at validation are still distributed to the TE, if active and available, without regard to the limit. Note: The MUI may be modified when appropriate, but not below the 500-case minimum for SP 1040-X TEs. Exception: The MUI for TEs that have finished their new hire training class and are on Skill Set "a" and "b" learning curve, the MUI minimum is 200 cases. The VpD limit is 75 cases. This limit is total number of cases a TE receives daily through the auto-distribution process. Cases that are created using TE's number in CII at validation are still distributed to the TE, if active and available, without regard to the limit. Note: The VpD may be modified when appropriate, but not below the 75-case minimum for SP 1040-X TEs. The Skill Set is used by the CII system to identify the Document Type (Doc Type) to be auto-distributed to a TE. The CII Skill Sets for SP 1040-X are: SP 1040X SP 1040X W7 SP 1040X CP 08 SP 1040X CP 09 SP 1040X CP 27 Note: All TEs, once finished with their new hire training class, are required to have their CII profile setup for CII Skill Sets "1" and "2" shown above. Once a TE's learning curves for skills "1" and "2" have been completed, the CP notice skill sets are to be add to the TE's CII profile. In the event a TE depletes their active inventory and TE needs cases before the next auto-distribution, a manager, or lead, is able to manually reassigns cases from the auto-distribution queue directly to the TE. When manually reassigning cases from the auto-distribution queue to a TE: Verify what Doc Types the TE is profiled to process. Refer to paragraph 5 above. Determine which cases in the auto-distribution queue contains the oldest cases the TE is eligible to process based on the TE's profile. Reassign the oldest cases by Doc Type to the TE. Note: If manually reassigning cases, the MUI limit may need to be increased. To temporarily stop distribution of cases to a TE, when on leave for example, set the volume per day to zero. Don't set TE's CII Availability to "Unavailable" for brief, temporary absences.

# Amended Return Processing Overview

3.11.6.4 (07-10-2025) Amended Return Processing Overview Taxpayers can add, delete, update, or change tax information reported on their original tax return, including amounts adjusted by the IRS, by filing an amended return. Generally, taxpayers need to complete and submit, electronically or by mail, a Form 1040-X, Amended U.S. Individual Income Tax Return, to amend their original return, but they do have the option to use Form 1040, U.S. Individual Income Tax Return, Form 1040-SR, U.S. Tax Return for Seniors, or Form 1040-NR, U.S. Nonresident Alien Income Tax Return. Regardless of the filing method used, SP 1040-X tax examiners use the CII system when processing amended returns. Certain amended returns received electronically are processed through automation. If an electronically filed amended return isn't processed through automation, it will be transferred to the CII system for manual processing. Amended returns received by mail are digitized for processing. The general sequence is to determine if: Routing criteria is met. The claim is complete. The claim is allowable. The claim is processable. When processing amended returns and CP Notices, use IDRS, AMS, CII, EUP, and RRD. Use of IAT tools is required. IRM instructions take precedence over any instructions, directions or default inputs the IAT tools provide. If specific IRM instructions are not present, accept the IAT Tool results. Note: Prior to using the IAT tools, you must setup and complete your IAT profile. Researching previous tax years may assist in processing a return. Tax examiners must have a valid business reason to access related accounts. When instructed to treat a case as classified waste, see IRM 3.11.6.17.22, Classified Waste.

# Amended Return Preliminary Review

3.11.6.5 (01-02-2025) Amended Return Preliminary Review Occasionally, taxpayers file multiple returns or CP Notices and each require a Document Type (Doc Type) for the CII system. Refer to IRM 3.11.6.5.8 (2), Updating Case Data, for the CII Doc Types used by SP 1040-X. Multiple filings for the same tax year (TY) requiring the same Doc Type, result in a CII case having multiple return images. Multiple filings requiring different Doc Type will have a have multiple CII cases. If ... And ... Then ... The taxpayer filed an amended return for TY 2024 on paper The taxpayer submits another amended return for TY 2024 on paper and the CII case for the first return is still open The second return will be present on the existing CII case. The taxpayer filed an amended return for TY 2024 on paper The taxpayer submits another amended return for TY 2024 on paper and the CII case for the first return is closed The second return creates a new CII case. The taxpayer filed an amended return for TY 2024 on paper The taxpayer submits another amended return for TY 2024 electronically and the CII case for the first return is still open The second return will be present on the existing CII case. Caution: You need to search RRD for an amended return for the same TY. Exception: If the paper filed amended return is received from the ITIN, then a new case is created for the second return. The taxpayer filed an amended return for TY 2024 electronically The taxpayer submits another amended return for TY 2024 on paper and the CII case for the first return is still open The second return will be present on the existing CII case. The taxpayer responds to a CP notice The taxpayer submits an amended return for the same TY on paper or electronically Then a new CII case is created for the amended return. If a CII case has more than one imaged return follow the table. If ... And ... Then ... The imaged returns are duplicates Process the case using the earliest complete return. The imaged returns are not duplicates They are for the same taxpayer, tax year, and routing criteria isn't present Process each case separately. Reminder: When inputting multiple adjustments, a posting delay code is required. Caution: Don't close the CII case until all adjustments have been completed. The imaged returns are not duplicates They are for the same taxpayer, tax year, and routing criteria is present Route the entire CII case following normal procedures. When multiple CII cases are present, determine if the other case(s) are unassigned. See the generic queue list in IRM 3.11.6.3, Controlling Cases on the CII System. Determine if the CII case return is a superseding, duplicate, or amended return. Before an adjustment can be input or sent to another function, check the return for the following elements: Taxpayer Identification Number (TIN) Tax period Received date Control base Presidential Election Campaign Fund (PECF) requests TC 150 posted When instructed to treat a case as classified waste, see IRM 3.11.6.17.22, Classified Waste.

# CII Split Image Request

3.11.6.5.1 (01-02-2024) CII Split Image Request A split image request is required when two or more unrelated cases have been erroneously scanned as one CII image. There are two types of split requests, simple and complex. A simple split request can be done on cases when two or more cases are in sequential order with all forms and schedules. A complex split request is where two or more cases or images are commingled in one case. Note: Refer to the 1040-X Job Aid for more information on splitting a CII image. If an entire image needs to be moved from a case, follow IRM 3.11.6.5.1.1, CII Move Image Request. A simple split request is submitted as follows: The TE must choose "SPLIT-IMAGE" from the "Suspend" drop-down list to open the "Split Image Details" screen. On the "Split Image Details" screen take the following actions: • Click the radio button next to the CIS image icon to start the simple split process. • In "Step 1" indicate the last page included with the current case by clicking on the appropriate page number and click the "Add Split" button. The lead or manager must retrieve the request from their "Approval" inventory and determine if the request is being accepted or denied. If denying the request leave a case message stating the reason for the denial. Note: Once the approval or denial process has been completed, the case must be sent back to the TE's "Active" inventory. The TE must retrieve the case and review the case for any case messages from the lead or manager. If the request was denied, review the reason for the denial and submit another request if needed. If the request was approved, continue processing the case. A complex split request is submitted as follows: The TE must enter a case message stating "Complex split request. Pages (XX -XX) belong with the current case. Pages (XX - XX) belong to New Case (A, B, C, etc.)." Then, the TE notifies the lead or manager that (CII case number) requires a complex split. The lead or manager must search for the case in the TE's inventory and review the case message. After reviewing the case message, the lead or manager must use the Split Image tool located in the "CII Administration" menu to verify the split information to determine if the request is approved or denied. • If approved, the tool must be used to split the case. Once the case has been split, the TE must be notified. • If denied, leave a case message stating the reason for the denial and inform the TE. The TE must, upon receiving notification, retrieve the case and review the case for any case messages from the lead or manager. If the request was denied, review the reason for the denial and submit another request if needed. If the request was approved, continue processing the case.

# CII Move Image Request

3.11.6.5.1.1 (01-02-2024) CII Move Image Request A move image request is required when two or more images have been scanned to one CII case and at least one of the images doesn't belong to the CII case. When an entire image needs to be moved to another CII case, the image move request is submitted as follows: The TE must enter a case message stating "Image move request. Image (xxxxxxxx) belongs to the current case. Image (xxxxxxxx) belongs (a new case or existing CII case number)." Then, notify the designated employee at your site that (CII case number) requires an image be moved. The designated employee must search for the case in the TE's inventory and review the case message. After reviewing the case message, the designated employee will determine if the request is approved or denied. • If approved, the image will me moved. Once the image has been moved, the TE must be notified. • If denied, leave a case message stating the reason for the denial and inform the TE. The TE must, upon receiving notification, retrieve the case and review the case for any case messages from the designated employee. If the request was denied, review the reason for the denial and submit another request if needed. If the request was approved, continue processing the case. To move an image, take the following action: Open the CII case with the multiple images. In the "Images and Files" section click on "Edit Image Details" for the image you want to move to another case. On the "Edit Image Details" screen, the action taken will depend on the move request received. If the request received is to: • Move an image to an existing case, input the CII Case ID of the case where the image needs to moved into the "Move to Existing Case" field. • Move an image to a new case, click the "Move to New Case" checkbox. Click "Save" to complete the request.

# Associating Forms, Schedules, and Other Documents to CII Cases

3.11.6.5.2 (01-01-2026) Associating Forms, Schedules, and Other Documents to CII Cases Occasionally, when working a case, tax examiners will need to send a form, schedule, and other document to associate with the case they're working. The CII case association process must be completed prior to the case being reassigned, rerouted, or closed. The tax examiner must prepare the CII Association Header Sheet and input a case note stating what form(s), schedule(s), or other document(s) are being sent for association to the case. TIN - Use the primary TIN Name Control - Use the primary name control MFT - Use "30" Tax Period - Use the tax period of the case Received Date - Use the received date of the amended return Case ID - Use the CII Case ID of the case being worked Employee number- Use your IDRS employee number Send the case to ICT for association through the exception scanning.

# Tax Period

3.11.6.5.3 (01-02-2025) Tax Period Amended returns must be for a specific tax period. When the tax period is missing and you can't determine the tax period from return information or attachments, research IDRS for matching tax data. Note: If the tax period is incorrect on a case, update the case data to the correct tax period per IRM 3.11.6.5.8, Updating Case Data. If the tax period can be determined, edit the tax period on the front of the return above the Entity section in YYMM or YYYYMM format or mark the appropriate box, if available. If you can't determine the tax period through IDRS research, correspond unless return is being sent to another function. Correspond per IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins, and use the tax period of the CII case when sending the letter. If the taxpayer submitted an amended return for multiple tax periods on a single amended return, correspond. See IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins.

# Taxpayer Identification Number (TIN)

3.11.6.5.4 (01-02-2024) Taxpayer Identification Number (TIN) To process a return, the taxpayer must have a TIN. The IRS uses four different types of TINs when processing IMF Taxpayer accounts. The following table contains the type of TINs and their format: TIN Type Format Social Security Number (SSN) - If followed by an asterisk (*) it is a temporary or "invalid" number. xxx-xx-xxxx Individual Taxpayer Identification Number (ITIN) - This number is assigned by the Austin campus ITIN Operation as a result of an accepted W-7, Application for IRS Individual Taxpayer Identification Number, or W-7SP application. 9xx-NN-xxxx Note: The fourth and fifth digits of a valid ITIN range are: - 50 through 65 - 70 through 88 - 90 through 92 - 94 through 99 Adoption Taxpayer Identification Number (ATIN) - This number is assigned by the Austin campus as a result of an accepted W-7A application. 9xx-93-xxxx (always "93" for 4th and 5th digits) Internal Revenue Service Number (IRSN) - This number is assigned by the IRS. 9xx-NN-xxxx Note: The fourth and fifth digits of an IRSN are the IRS service center code. See IRM 3.13.5.23, Internal Revenue Service Number (IRSN) Format. For ITINs, see IRM 3.11.6.17.14.2, ITIN Status. If the Primary TIN (P-TIN) or secondary TIN (S-TIN) is missing, incorrect, or illegible for a taxpayer with the FS of married filing jointly, research per IRM 3.11.6.13.1, Entity Changes. If found, edit to the appropriate field on the amended return. Note: When processing a case, update the Case Data to correct P-TIN per IRM 3.11.6.5.8, Updating Case Data. If you have exhausted all resources and are still unable to determine the P-TIN and/or S-TIN, correspond per IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins. Send to AM, if: The taxpayer makes changes to the primary or secondary taxpayer's TIN. The P-TIN or S-TIN is invalid. The primary or secondary taxpayer is changing from an ITIN or IRSN to an SSN. The primary or secondary taxpayer's account is set up on the invalid segment of master file (which requires an asterisk after the TIN (000-00-0000*). A pound sign after the TIN (000-00-0000#) is an indication of a newly assigned TIN. Don't treat as an invalid TIN. Exception: If the FS is MFS (FS 3), the spouse's TIN may show an asterisk after the TIN. This mustn't be considered an invalid TIN and can be worked as normal. A FS change to Married Filing Jointly (MFJ) and both taxpayers have already filed. The case involves merged (re-sequenced) account and an update to CC DDBCK or CC DUPED is required. Note: A merged (re-sequenced) account will have a transaction code 011, 013, 040 or 041 on CC ENMOD. Mixed entity cases where more than one taxpayer has attempted to file under the same TIN and: • It isn't possible to verify the correct TIN through research, or • Research verifies that both individuals have used the TIN in other tax years, or • CC INOLES shows that both taxpayers have been listed under this TIN Scrambled SSN cases where CC INOLES has an entry beside the Scrambled SSN Prompt and Numeric Indicator, except blank, 00, 08, 21, or 22. For TY 2019 and later, if the taxpayer indicates a religious (e.g., "Amish" , "Mennonite" , or "Form 4029" , Application for Exemption From Social Security and Medicare Taxes and Waiver of Benefits) or conscience-based objection to obtaining a TIN. If the taxpayer is filing MFJ and there's no TC 150 posted for the primary's TIN, research the secondary's TIN for a TC 150. TC 594 may be present. See IRM 3.11.6.6.1, TC 150 Research (No TC 150).

# Protecting Americans from Tax Hikes (PATH Act)

3.11.6.5.4.1 (01-02-2024) Protecting Americans from Tax Hikes (PATH Act) The Protecting Americans from Tax Hikes Act (PATH Act) was enacted December 18, 2015. The PATH Act prohibits taxpayers from retroactively claiming certain credits for any tax year in which the taxpayer, spouse or qualifying child doesn't have a valid TIN issued on or before the due date, or extended due date, of the return or, if the taxpayer, spouse, or qualifying child has an inactive TIN. The PATH Act applies to: Child Tax Credit (CTC) Additional Child Tax Credit (ACTC) Credit for Other Dependents (ODC) American Opportunity Credit (AOTC) - both refundable and non-refundable Earned Income Tax Credit (EITC) CP notices 08, 09 and 27 Credit-specific eligibility requirements apply in addition to the PATH Act criteria. A TIN that is valid to claim a particular credit may not be valid to claim a different credit. The PATH Act prohibits current year refunds of EITC or ACTC before February 15. All amended returns without a C- freeze that add EITC or ACTC must be held until then. The TIN validations required by the PATH Act isn't applied to superseding returns that have already passed TIN validations. Exception: If there's a TIN present on the superseding return that wasn't on the original return, the new TIN requires PATH Act validation. If processing W-7 returns, see IRM 3.11.6.17.14.1, Returns Received From the ITIN Unit (Form W-7). Don't remove PATH Act credits previously allowed due to a FS change to married filing jointly (MFJ) unless initiated by the taxpayer. Apply the PATH Act using the following table: Exception: If EITC is involved, see IRM 3.11.6.15.4, Earned Income Credit (EIC) - Line 14. If ... And ... Then ... The spouse has a newly assigned ITIN The XRET is for the current processing year, or the assignment date is more than 90 days after the return due date or due date as extended for a prior year Disallow the claim. Input the adjustment per IRM 3.11.6.11.5, Correspondence for Disallowing a Claim (Letter 105C, Letter 105SP, Letter 106C, and Letter 106SP), and follow (8) below. The spouse has an SSN The SSN was issued after the return due date Disallow the claim. Input the adjustment per IRM 3.11.6.11.5, Correspondence for Disallowing a Claim (Letter 105C, Letter 105SP, Letter 106C, and Letter 106SP), and follow (8) below. The spouse has an SSN The SSN was issued on or before the return due date or due date as extended Process the return. The spouse has a newly assigned SSN The SSN was issued after the return due date and EITC is increasing Disallow the additional EITC. Input the adjustment per IRM 3.11.6.11.5, Correspondence for Disallowing a Claim (Letter 105C, Letter 105SP, Letter 106C, and Letter 106SP). Don't remove existing EITC. The spouse has a newly assigned SSN The SSN was issued after the return due date and EITC is decreasing Decrease the EITC. The spouse has a newly assigned SSN The SSN was issued on or before the return due date Process the return. Research is required prior to adding PATH Act credits. To qualify, the correct TIN required for the particular credit(s) claimed must have been assigned on or before the due date, or due date as extended, of the return being processed. Use CC INOLES - TIN ASGNMT to research when the TIN was issued. If ... Then ... The "TIN ASGNMT" field contains a date on or before the due date of the return Note: ITINs assigned within 7 days of the return due date are considered timely. Allow the credit if all other criteria are met. The "TIN ASGNMT" field is all zeros Allow the credit if all other criteria are met. The "TIN ASGNMT" field contains a date after the due date of the return Disallow the claim. Input the adjustment per IRM 3.11.6.11.5, Correspondence for Disallowing a Claim (Letter 105C, Letter 105SP, Letter 106C, and Letter 106SP) and follow (9) below. When a PATH Act credit(s) has been disallowed, input a TC 971 AC 113. Use the received date for the transaction date. Enter the total of all PATH Act credit(s) claimed on Form 1040-X that are being disallowed in the "Freeze Release>" field.

# TIN Requirements for Credits

3.11.6.5.4.2 (01-01-2026) TIN Requirements for Credits The tables below provide a quick reference to determine the TIN requirements for exemptions and certain credits. Always research for specific requirements including but not limited to the form, statute, and PATH Act.

# Received Date

3.11.6.5.5 (01-01-2026) Received Date Every return must be stamped with a received date stamp. An Official Received Date Stamp must consist of no less than: The word "Received" Month (alpha or numeric) Day - (for example, can be "1" or "01" ) Year - four digits "Area Office (AO)" , "Lockbox (LB)" , Campus, "Field Office" , "Taxpayer Assistance (TAC)" plus the location city, or functional area within one of these sites (e.g., Compliance Service Collections Operation (CSCO), Exam, Image Control Team (ICT), CII, AM, etc.) Note: Not all IRS offices are designated places for filing, and not all IRS employees are authorized to accept a tax return for processing. If a return contains a received date stamp from other than a Taxpayer Assistance Center (TAC), Lockbox, or IRS campus (Compliance, AM, or SP), circle out the invalid received date and edit the correct received date according to instructions in paragraph 4 below. For example, returns received by TAS or the IRS Office of Chief Counsel are not properly filed and a received date by that office isn't the official "IRS Received Date." On MEFP cases, the RRD field labeled "Received Date" is the received date of the return. The RRD field labeled "IRS Received Date" is an electronic postmark used to determine return timeliness. Note: See the 1040-X Job Aid for additional information. If the Received Date stamp on an MEFS or LSFM case is missing from the front page, or is illegible, but is found elsewhere in the return packet, add the received date to the front of the return in MMDDYYYY format in the blank space above line 1. Caution: When editing the received date, check the case data and update if needed. Use the following table for CII cases processed by SP 1040-X: If ... Then ... Editing a received date is required on a case imaged into CII. Use the CII "Annotation Toolbar" to add the received date. A case has multiple identical images with multiple received dates. Use the received date from the earliest complete return. Honor received dates that are handwritten in the center portion of the amended return edited in: Green ink on current year returns received with payments as the return received date. Red ink located in the center portion of the amended return. Caution: When working a scanned CII case, the image is in black and white. Honor the received date handwritten in the center portion of the amended return. If the Received Date stamp isn't found or is obviously incorrect, edit the received date based on the order of precedence below in the same format and location as stated in (3) above. Latest postmark or designated private delivery service mark on the envelope IRS service center Automated Mail Processing System (SCAMPS) date Signature Date (only if the return was signed in the current year) Current date Caution: Using a received date later than the ICT date is an obviously incorrect date and mustn't be used. In this instance, use the ICT date if an earlier received date is not found on the return. When there are multiple received dates stamped, or edited, on the return and you're adjusting or sending an amended return to another area, use the earliest received date. When processing replies to correspondence, see IRM 3.11.6.11.3, Corresponding on Net Balance Due Returns (Letter 324C), IRM 3.11.6.11.4, Corresponding on Net Refund and Zero-Balance Returns (Letter 178C), or IRM 3.11.6.8.10, Statute Review Screening. Input the received date of the return you're processing as the received date on IDRS. If the received date of the return doesn't match the established control base, see IRM 3.11.6.3, Controlling Cases on the CII System. Exception: For Statute returns, see IRM 3.11.6.8.10, Statute Review Screening. OVERRIDE CODE - An Override Code is required when the IRS Received Date is over one year old and on cases when the RSED has expired. R - Allows IRS Received Date to be older than a year in the past. S - Allows current date and the Refund Statute Control Date (RFSCD) to be later than the RSED. Refer to IRM 3.11.6.8.10, Statute Review Screening.

# Determining Timeliness

3.11.6.5.5.1 (01-01-2026) Determining Timeliness Always use the received date when determining timeliness of the claim. If the received date is missing, see IRM 3.11.6.5.5, Received Date. When the postmark is missing or illegible consider any return received within ≡ ≡ ≡ ≡ ≡ ≡calendar days of the due date of the return timely. Reminder: On MEFP cases, the RRD field labeled "Received Date" is the received date of the return. The RRD field labeled "IRS Received Date" is an electronic postmark used to determine return timeliness. See the 1040-X Job Aid for additional information. April 16 is Emancipation Day in Washington D.C., a legal holiday. This may affect when a return is considered to be timely filed for taxpayers throughout the United States. See also IRM 25.6.1.6.18, List of Legal Holidays. When April 15 falls on a Sunday, the following Monday is generally the day on which returns are timely filed; however, in Washington D.C., April 16 is Emancipation Day, a legal holiday. All taxpayers have until Tuesday April 17 to file a timely return. When April 16 falls on a Saturday, Friday April 15 is considered the holiday. All taxpayers have until Monday April 18 to file a timely return due to the Emancipation Day holiday. When April 16 falls on a Sunday, Monday April 17 is the date of the Emancipation Day holiday. All taxpayers have until Tuesday April 18 to file a timely tax return due to the Emancipation Day holiday. Use the following table to determine if the claim is considered timely filed: If April 15 falls on ... Then the postmark must be ... Friday April 18 or earlier. Saturday April 18 or earlier. Sunday April 17 or earlier. Caution: Disaster declarations may impact return due dates. These timeliness instructions affect the processing of: Statute returns, see IRM 3.11.6.17.1, Processing Statute Cases Superseding returns, see IRM 3.11.6.5.5.2, Superseding Returns Returns involving PATH Act credits, see IRM 3.11.6.5.4.1, Protecting Americans from Tax Hikes (PATH Act)

# Superseding Returns

3.11.6.5.5.2 (02-03-2025) Superseding Returns All superseding returns must be screened following IRM 3.11.6.8.11, Superseding Return Discriminant Function (DIF) Score Screening. The due date of a calendar year individual income tax return is April 15. Note: A fiscal year individual income tax return is due the fifteenth day of the fourth month following the close of the fiscal year. The due date may be changed due to Presidential disaster declarations. An amended return: Filed on or before the due date or the extended due date is a superseding return. Postmarked on or before the due date or extended due date, is processed as a superseding return. Send to AM any superseding return if: The return meets DIF score criteria. The return doesn't meet DIF score criteria and the AIMS status on CC AMDISA status is 09 or greater. The return doesn't meet DIF score criteria and meets CAT-A criteria. The adjustment would result in an unpaid net balance due increase on the module. The refund claim must be disallowed, partially disallowed, or not considered, leaving the account with a balance due instead of a refund.

# Amended Claims Date

3.11.6.5.5.3 (09-25-2020) Amended Claims Date The Amended Claims Date is a REQ54 field that is used by Master File to apply the 45-day interest free period. Use the IRS Received Date as the Amended Claims Date. For suspended correspondence, the Amended Claims Date is the received date of the taxpayer's reply that allows you to process the return. An Amended Claims Date is required on every adjustment unless specifically noted otherwise. Don't use an Amended Claims Date when processing CP 08, CP 09, CP 27 or Math Error Corrections (only when the math error was set on the original return). When making a received date determination, see IRM 3.11.6.5.5, Received Date.

# Signature

3.11.6.5.6 (01-02-2025) Signature The claim or amended return requesting an adjustment must be signed by (1) the taxpayer or (2) a person holding a valid POA who has been authorized by the taxpayer to sign the taxpayer's return by checking box on Form 2848, line 5a. The signature(s) is required anywhere below the jurat (perjury statement), but not in the paid preparer section on amended returns. If an original signature isn't present on a CII case, correspond per IRM 3.11.6.11, Correspondence Procedures, IRM 3.11.6.11.3, Corresponding on Net Balance Due Returns (Letter 324C), IRM 3.11.6.11.4, Corresponding on Net Refund and Zero-Balance Returns (Letter 178C), and IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins. See IRM 3.11.6.17.15 (8), CP Notices, for CP 08, CP 09, and CP 27 signature requirements. All accepted e-filed returns have a valid signature. Caution: Rejected e-filed returns may also be present on RRD. Only accepted returns are sent to SP 1040-X for processing. If the jurat has been altered, treat it as a Frivolous claim. If the jurat is missing, treat it as an unsigned return and correspond for the missing signature(s) using Letter 324C to obtain the signature. Process the net balance due per IRM 3.11.6.11.3, Corresponding on Net Balance Due Returns (Letter 324C). Don't correspond for a missing or incorrect signature(s) if: A "Dummy" return was prepared by the IRS. A fiduciary representative or parent for other than a minor child signs for a ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡. Form 2848, Power of Attorney and Declaration of Representative, with specific authorization on line 5a to sign a return, and including completed Part II, is attached to the return. See IRM 3.11.6.5.6.1, Centralized Authorization File (CAF) - Form 2848, Power of Attorney (POA) and Form 8821 (TIA) and General /Durable POAs. The return is a duplicate. Taxpayer files MFS (FS 3) and spouse didn't sign the return. The return is a substantiated math error response. The claim meets routing criteria unless otherwise specified. Note: For decedent returns, see IRM 3.11.6.17.10, Decedent Returns. If Form 1040-X isn't signed, however a Form 1040 matching the Correct Amount column of Form 1040-X is attached and signed, accept the signature and continue processing the return. Edit a notation onto the signature line, if present, on Form 1040-X indicating that the Form 1040 is signed. Otherwise edit the notation on the front bottom portion of Form 1040-X. Correspond for the signature of two witnesses, if missing, when the taxpayer signs with a mark such as an "X" . See IRM 3.11.6.11, Correspondence Procedures. Joint returns require the signature of both taxpayers unless one of the taxpayers falls into one of the categories below: One spouse is overseas, and the signing spouse is authorized by a power of attorney (e.g., Form 2848) or similar signed document which clearly defines the scope of authorization granted to the POA. One spouse is in a combat zone/qualified hazardous duty area and the signing spouse attaches a statement. One spouse is incapacitated. The signing spouse must attach a dated statement explaining the reason the incapacitated taxpayer can't sign. The signing spouse signs on the signature line as well as the spouse's signature line. Caution: Incapacitated means the taxpayer is physically unable to sign the return. In the case of a mentally incompetent taxpayer a court appointed representative who can act for the taxpayer must sign the tax return. If MFJ return with only one signature and the taxpayer is divorced or separated, send the case to AM. If the taxpayer is a minor (there must be a clear indication the child is a minor) the return must be signed by one of the following: The minor child A parent A guardian or other fiduciary representative ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ A guardian or other fiduciary representative with documentary evidence is attached Note: Fiduciary representatives include: • Administrator (ADM) • Conservator (CONS) • Custodian (CUST) • Executor (EXEC) • Guardian (GDN) • Personal Representative (PER REP) • Trustee (TTEE) If taxpayer is a minor and the return is not signed, correspond for a missing signature.

# TC 150 Research (No TC 150)

3.11.6.6.1 (02-14-2024) TC 150 Research (No TC 150) All amended claims require a posted TC 150, unless specifically instructed. Specific instructions to route a case without a posted TC 150 take priority. Research IDRS using the primary taxpayer's TIN to locate a TC 150 for the tax period indicated on the return. Researching for a TC 150 includes researching both the valid and invalid sides of Master File. To research the invalid side, input an asterisk after the TIN. Note: It might be necessary to research different tax years if the information on the return or the data on IDRS support a different tax period. If ... And ... Then ... Researching the primary taxpayer's TIN A TC 150 wasn't found under the primary taxpayer's TIN Research CC TRDBV for tax data. If the tax data is present or is pending (must be present on primary taxpayer for MFS (FS 3)) suspend the case for 60 days from the received date and monitor for the TC 150 to post. Don't consider REJECTED, DELETED OR VOIDED on CC TRDBV as tax data. Note: A Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return, won't post as a TC 150, and isn't considered tax data. Exception: If you find master file information on CC TRDBV, but there's not information posted on MFT 30 research CC IMFOLI to see if information has posted to MFT 32 and if present, treat the case as identity theft. See IRM 3.11.6.8.9, Identity Theft (IDT) Screening. Researching the primary taxpayer's TIN A TC 150 wasn't found under the primary taxpayer's TIN Look though the entire return for a different TIN for the primary taxpayer, including taxpayer's explanation. If a different TIN is found, research for a TC 150 using the discovered TIN. A TC 594 is present The case is a MFJ return Research for a TC 150 using the cross-reference TIN. A TC 594 is present The case isn't a MFJ return Research for a TC 150 using the cross-reference TIN.

# Duplicate Returns and Identical Open CII Cases

3.11.6.7.5 (01-02-2024) Duplicate Returns and Identical Open CII Cases A duplicate condition occurs when: Multiple open CII cases are identical An amended return matches the most recent adjustment/filing figures When other open CII case(s) are present and assigned to the generic queue, determine if the other case(s) are identical to your case. If so, process as follows: Link the cases using the "Link" function on the "Active Case" page. In the Link Case popup, input the CII Case ID of the case(s) to be linked, one at a time. Notate "duplicate amended return" in the notes section of the identical case(s). Reassign the unassigned case to your CII case inventory. Close each CII case linked to the original case using the "Close as Misc" button. Continue processing the original CII case per normal procedures. Reminder: If a case is open to another SP 1040-X tax examiner, refer to IRM 3.11.6.8.18.1, Cases Open to an SP 1040-X Tax Examiner. Prior to treating an amended return as a duplicate, review the return and attachments for routing criteria. If the return is a duplicate but the taxpayer is requesting an additional action, follow general processing procedures. Research IDRS for taxpayer correspondence. Research the type of letter(s) that have been sent. Send the case to the originating area. This includes the Letter 12C requesting a taxpayer signature. When it appears that Code and Edit has corresponded for a signature (Form 3531 attached or notated in the working trail) and the return is still unsigned, follow normal procedures and send the case to Entity. If the return is a duplicate, don't correspond for missing forms, schedules, or signature(s). When processing a CII case, continue researching to determine the reason the taxpayer filed the form. If ... And ... Then ... The taxpayer has requested a processable change that doesn't cause a change to a line-item dollar amount The change has a specific RC Input a TC 290 .00 with the appropriate RC. The taxpayer has requested a processable change that doesn't cause a change to a line-item dollar amount The change doesn't have a specific RC Use RC 099. No change or action is required Input a TC 290 .00 without a RC. Note: If there's a prior pending adjustment, input a post delay code. Once a Form 1040/A/EZ/SR is identified as an amended return and that reverts the module back to the original filing, look for any indication as to why. If no indication is found, then treat the return as classified waste. See IRM 3.11.6.17.22, Classified Waste. Exception: If an active Combat Zone return, per IRM 3.11.6.17.4, Combat Zone, will revert the module to the original filing, input a TC 290 .00 without a RC.

# Sorting, Routing, and Priority Screening

3.11.6.8 (01-02-2024) Sorting, Routing, and Priority Screening Before inputting an adjustment or corresponding, screen the case to identify all documents and IDRS conditions requiring actions by another area. Occasionally, a Form 4442, Inquiry Referral, or E-4442, may be received from another area. Expedite the processing of these requests. When screening a case: Identify all possible route out criteria, then send to the highest priority as stated in paragraphs 4 and 5 below Note: Specific routing instructions found within the designated priority order take on that priority. Example: A case has a -W freeze and a -L Freeze (status code 12) on the account, and it also meets AUR open case criteria. In this instance, the three possible routing destinations for this claim are Exam, AUR, and AM. Since Exam is the highest priority and has specific instructions regarding the -W freeze, the case bypasses the AUR criteria and will be sent to AM. Follow specific IRM instructions CII cases are reassigned or rerouted through CII whenever possible. See IRM 3.11.6.10, 1040-X Reassignment and Reroute Guide Caution: When reassigning a case through CII, don't close the case control. Closing the case control causes an "E-1" error. If the TC 150 has not posted, see IRM 3.11.6.6.1, TC 150 Research (No TC 150) Don't input or update CC REQ54, CC DUPED, CC DDBCK or CC ENREQ unless otherwise instructed by a specific IRM subsection Input a case note and see IRM 3.11.6.8.20.1, Working Trail and Action Trail Note: Keep all related tax years together if possible. Exception: Don't route non-statute year returns to the Statute unit unless they are attached to a statute year return for informational purposes. Don't route a non-AUR cases to AUR unless they are attached for informational purposes If Form 1040-X needs must be converted to a Form 1040 or Form 6114, follow the association process in IRM 3.11.6.5.2, Association, Forms, Schedules, and Other Documents to CII Cases, prior to routing. See IRM 3.11.6.8.20.2, TC 971 and Action Codes, for TC 971 Action Codes and routing destination for specific items. See IRM 3.11.6.5.7, Processing Presidential Election Campaign Fund (PECF) Requests, for "Dummy PECF" editing instructions.

# Disaster Claim Screening

3.11.6.8.7 (01-01-2026) Disaster Claim Screening Taxpayers who are affected by a declared disaster will have a -O freeze (TC 971 AC 087) or -S freeze (TC 971 AC 688) on the module. Taxpayers no longer self-identify for disaster relief by writing a disaster designation in red at the top of their tax return. When the IRS decides to extend tax relief to taxpayers affected by a disaster, a news release is issued to the public outlining the relief that is being granted. The news release advises those taxpayers who are located outside the declared area but whose necessary tax records were inside the declared area to call the Disaster Hotline to self-identify. See IRM 21.5.6.4.30, -O Freeze, and IRM 21.5.6.4.37, -S Freeze, for additional information. The Disaster Tax Relief Airport and Airway Extension Act of 2017, the Tax Cuts and Jobs Act (TCJA), the Bipartisan Budget Act of 2018, and the Further Consolidated Appropriations Act, 2020 provide special rules for some qualified disaster losses. The $100 limitation per casualty increased to $500 The 10 percent of AGI limit doesn't apply The standard deduction is increased by the net qualified disaster loss Apply the special rules for qualified disaster losses to: A major disaster declared by the President under section 401 of the Stafford Act in 2016 Hurricane Harvey or Tropical Storm Harvey after August 22, 2017 Hurricane Irma after September 3, 2017 Hurricane Maria after September 15, 2017 The California wildfires after October 7, 2017, and before February 1, 2018 A major disaster that was declared by the President under section 401 of the Stafford Act and that occurred in 2018 and before December 21, 2019, and continued no later than January 19, 2020 (except those attributable to the California wildfires in January 2018 that received prior relief). A qualified disaster loss also includes an individual's casualty or theft of personal-use property that is attributable to a major disaster that was declared by the President during the period between January 1, 2020, and February 25, 2021. Also, this disaster must have an incident period that began on or after December 28, 2019, and on or before December 27, 2020. However, this change does not include those losses attributable to a major disaster that has been declared only by reason of COVID-19 and must have ended no later than January 26, 2021. The definition of a qualified disaster loss does not extend to any major disaster that has been declared only by reason of COVID-19 (because the incident period for COVID-19 extended beyond January 26, 2021). Thus, given that the incident period for COVID-19 generally ran from January 20, 2020 to May 11, 2023, a loss due to COVID-19 is not a qualified disaster loss. Hurricane Ida disaster after August 28, 2021 For tax years 2018 through 2025, an individual's loss of personal-use property is deductible only if the loss is attributable to a federally declared disaster. Exception: Personal casualty or theft loss can only be deducted to the extent of casualty gains. When instructed to send a disaster claim to AM, use category code "KATX" if the disaster claim meets the criteria listed in paragraph 4 above, and use category code "DSTR" for all other cases. If a TC 150 hasn't posted on a disaster claim, send the case to AM. Screen the case for CAT-A criteria. Refer to IRM 3.11.6.8.15, Category A (CAT-A) Criteria Screening. Taxpayers claiming a disaster loss must file Form 4684, Casualties and Thefts. The taxpayer may file a claim for the year of the disaster or may elect to claim the loss in the tax year preceding the disaster year. Correspond using Letter 324C if: The Form 4684 is missing The disaster claim is missing a signature. Suspend the return until you secure a signature only on refund returns - If a reply is received within 45 days, continue processing the return and input under Blocking Series 05 - If no reply is received after 45 days, send a Letter 916C, per IRM 3.11.6.11.8, Correspondence for No Consideration of a Claim (Letter 916C and Letter 916SP). Input a TC 290 .00 to file the return The federally declared disaster designation isn't listed in Section A(1) of Form 4684 (for 2018 through 2025) Verify the taxpayer had a loss in a qualified disaster area via the IRS Disaster Assistance Program If ... Then ... The loss is claimed for the tax year in which the disaster occurred The return must be filed within three years of the due date of the return for the tax year in which the disaster occurred, without extensions. The loss is claimed for the tax year preceding the tax year in which the disaster occurred The election must be made on or before 6 months after the due date for filing your original return (without extensions) for the tax year in which the disaster occurred. A disaster claim isn't filed within the timeframes above Send the case to AM. The disaster claim is timely filed Process the claim following IRM 3.11.6.17.2, Processing a Disaster Claim. Example: A disaster occurs in August 2024, and the loss is sustained in 2024. The taxpayer can elect to timely file the disaster loss for 2023 until October 15, 2025. Alternatively, the taxpayer could choose to file the loss for the 2024 tax year and has until April 15, 2028, to claim the loss via an amended return. Follow normal processing procedures if the return isn't a disaster claim.

# Carryback and Carryforward Screening

3.11.6.8.8 (07-30-2024) Carryback and Carryforward Screening To screen a case for carryback issues, refer to IRM 3.11.6.8.8.1, Carryback Claim Screening. To screen a case for carryforward issues, refer to IRM 3.11.6.8.8.2, Carryforward Claim Screening. Then reassign the case to the appropriate queue per IRM 3.11.6.10.1, MEFP Reassignment and Reroute Guide, or IRM 3.11.6.10.2, MEFS Reassignment and Reroute Guide, as appropriate. If the case is 60 days or less before the ASED expires, or if the ASED has expired, leave a case note stating, "CB/CF/Statute Imminent" . Leave a CC ACTON history item "STAT IMNT" .

# Carryback Claim Screening

3.11.6.8.8.1 (07-30-2024) Carryback Claim Screening When screening a case for carryback claim issues, refer to IRM 21.5.9.2.1, Identifying Carryback Applications and Claims. When screening a case for carryback credit claim issues, refer to IRM 21.5.9-1, General Business Credits, Foreign Tax Credit, and Other Non-Refundable Credits - Availability for Carryback/Carryforward, and IRM 21.5.9.5.3, Special Carryback/Carryforward Periods.

# Carryforward Claim Screening

3.11.6.8.8.2 (07-30-2024) Carryforward Claim Screening When screening a case for carryforward claim issues, refer to IRM 21.5.9.2.2, Identifying Carryforward Claims. When screening a case for carryforward credit claim issues, refer to IRM 21.5.9-1, General Business Credits, Foreign Tax Credit, and Other Non-Refundable Credits - Availability for Carryback/Carryforward, and IRM 21.5.9.5.3, Special Carryback/Carryforward Periods. When the taxpayer has is requesting an election to forgo the carryback period, check CC TRDBV for the literal "ELECTION" . If present, the election has already been made and the case doesn't need to be sent as a carryforward claim.

# Identity Theft (IDT) Screening

3.11.6.8.9 (01-02-2025) Identity Theft (IDT) Screening Identity Theft (IDT) can be indicated by the taxpayer's explanation, by markers on the account, or by suspicious changes identified by tax examiners. Accounts the IRS has identified as potential IDT contain one of the following indicators. If one of the following indicators is found, see paragraphs 3 and 7 below. CC ENMOD, IMFOL, or TXMOD: TC 971 with AC 506, 522 (with the literals UNWORK or IRSID) for the year of the amended return, or 524 (if the 1040X is for a tax year after the date of death). See paragraph 3 below for additional information Note: The Secondary Date (SECONDARY-DT>) field of one of the above indicators reflects the tax year affected by identity theft. If the tax period in question matches the year of the Secondary Date, see paragraphs 3 and 7 below. Exception: AC 524 may or may not have a SECONDARY-DT field entry. AC 524 is an identity theft indicator used to lock the account of deceased taxpayers. It prevents a deceased taxpayer's TIN (SSN or ITIN) from being used as the primary, secondary, or dependent TIN on a current or subsequent year federal income tax return. The TC 971 AC 524 indicator is applied systemically to the account and is effective the following year after the date of death. Example: Taxpayer's date of death is 6/03/2023. A return for TY 2023 can post but a return for TY 2024 won't. CC TXMOD or IMFOLT: TC 971 AC 111 CC IMFOLI: MFT 32 is indicated for the TY and No TC 150 is present on MFT 30. See paragraph 7 below Note: The IDT literal on CC ENMOD, CC IMFOLE, or other TC 971 Action Codes mustn't be used as an IDT indicator. Verify IDT indicators have not been reversed prior to routing. If a TC 972 is present reversing the IDT indicator, don't route the return unless there are additional indicators present. A taxpayer can self-identify as a victim of IDT by: Stating in the Explanation of Changes on Form 1040-X or a separate statement Completing Form 14039, Identity Theft Affidavit Responding to IRS correspondence related to IDT If the taxpayer indicates their dependent is a victim of IDT, send the case to AM. The taxpayer can indicate their dependent is a victim of IDT by: Stating in the Explanation of Changes on Form 1040-X or a separate statement Completing Form 14039, Identity Theft Affidavit Responding to IRS correspondence related to IDT Tax Examiners may identify suspected IDT when the return doesn't master file verify and when certain account changes seem suspicious such as large, unusual or questionable line-item changes. When this occurs use the following research steps to aid in determining if the return must be routed as IDT: Use CC RTVUE to verify: - Address for the first return(s) filed - Dependents - Type of Income - FS - Schedules and Forms filed Use CC TRDBV to verify: - Significant changes in the filing history - Occupation - Requested method of refund payment - Tax Preparer - Multiple attempts to file a rejected return Use CC DDBCK to verify: - Dependents and/or credits claimed on the original return Use CC IMFOLI to verify: - Number of years the TIN has been used - FS changes - Method of filing: paper or e-file Use CC IRPTR to verify: - Comparative review of reported income and payor information - Previous and current employer - Previous address Reminder: Before routing as IDT, you must have multiple suspicious changes between the original filing and the amended filing. Once a return is identified as being an IDT return or has IDT involvement: If ... Then ... Form 1040-X Input "IDT" in the case notes and a brief description of the IDT issue that has been identified. Send the case to AM. Form 1040 series In the upper left-hand corner of the return notate PAO (Process as Original). Circle out any notation that suggests the return was previously filed. Send the case to Batching. Form 1040-X with Form 1040 If a TC 150 is posted (or pending): Input "IDT" in the case notes and a brief description of the IDT issue that has been identified. Send the case to AM. Form 1040-X with Form 1040 If no TC 150 is posted or pending: "X" Form 1040-X. Edit PAO in the upper left-hand corner of the Form 1040. Circle out any notation that suggests the return was previously filed. Send the case to Batching. Undeliverable Send the case to Entity.

# Statute Review Screening

3.11.6.8.10 (01-01-2026) Statute Review Screening Beginning January 1, 2026, all returns for tax year 2022 and prior are considered statute year returns. Send any statute year case involving any of the following to AM: The 25% omission rule applies, per (4) below.

Amended returns that are SI must be hand carried by a manager to Statute, per IRM 25.6.1.9.9.2, After Hours and Imminent Assessments. Reminder: Review the case for the 25% omission rule to determine if the ASED is extended (TC 560) or needs to be extended per IRM 3.11.6.7.1, 25% Omission Screening. Exception: The hand carry requirement doesn't apply to cases on the CII system. IDRS research is required to determine if the amended return is a tax increase or credit decrease and to verify the ASED. When verifying the ASED, use today's date. Exception: A claim to decrease withholding isn't considered a credit decrease and is processable without statute involvement. If IDRS shows Form 1040-X ... And the ASED ... Then ... Line 11 is a total tax increase Expired Take the following action: Input a TC 971 AC 014 Suspend the case to Statute.

They may also argue that other laws or documents prevent the IRS from assessing and collecting tax, such as the Bible, Bill of Rights, Declaration of Independence, etc. Disclaimer - Taxpayer submits a disclaimer. The disclaimer states they "disclaim the liability of the tax due" , making the liability on the tax return zero. Employment Tax/CFR 1.861 - No employer is legally obligated to withhold income or employment taxes on employees' wages. Erroneous claims that taxes are only owed by persons with a fiduciary relationship to the United States or the IRS. Federal Reserve Notes Are Not Legal Tender - Taxpayer argues that Federal Reserve notes are not money, so they are not income when received.

Form 1099 MISC -Form 1099 MISC -The Frivolous Form 1099 is used to claim large refunds based on false income amounts and withholding. The false income typically is reported as Other Income.

Form 2555, Foreign Earned Income, is usually attached showing the taxpayer's "foreign address" is in the United States. The taxpayer also shows income on Form 2555 as "foreign earned income" even though the employer's address is also in the United States. Fuel Tax Credit Returns - Taxpayers submit returns that reflect fuel tax claimed for occupations that would not justify the use of fuel used for non-taxable purposes, such as hairdressers, housekeepers, nurse, etc. Realistically, the taxpayers would not have money sufficient to live on, if indeed they had purchased the amount of fuel on which they claimed the credits. Therefore, the claims remain so far beyond a reasonable range as to doubt good faith on the return in general. In Lieu of - Taxpayer submits a document containing personal identifying information and a summary of income received "in lieu of" an official income tax form. IRC 1001 -Taxpayer claims on Schedule A under "Other Miscellaneous Deductions" no gain realized for even exchange of property-Labor (property)-Employer's (property) with NO GAIN REALIZED Butcher's Union Co. v. Crescent City Co., 111 US 746 S.CT.Rptr., pp.660-661. IRC 83 - Claims, generally in the form of Form 843, Claim for Refund and Request For Abatement, request abatements of previously assessed taxes and/or penalties using IRC 83 as justification. The claims further describe that the abatement is based on an allegation that the taxpayer previously failed to compute, under IRC 83, the amount of property transferred in connection with the performance of services. IRC 1341 - Taxpayer claims compensation for personal labor isn't taxed by Title 26, IRC 1341, sometimes arguing that the taxpayer has a "claim of right" to exclude the cost or value of the labor. IRC 3121 - Taxpayer contends that IRC 3121 exempts the Federal Insurance Contribution Act (FICA) portion of earnings from the definition of "wages" and therefore from "gross income" for federal income tax purposes. The taxpayer attempts to reduce taxable income by their portion of withheld Social Security tax. IRS is a Private Organization/Collects Tribute, Not Taxes - Taxpayer argues that the IRS is an entity named the Internal Revenue and Tax Service, Inc. and since the IRS deposits its revenues in the Federal Reserve Bank, it is a collection agency for the Federal Reserve Bank. Additionally, the taxpayer argues the Department of Treasury is part of the United Nations and secretly leading the tax-paying public into a "New World Order" . Native American Indian Treaty- The filings usually include Form 1099-MISC or other income documents that include withholding and results in a refund. Mariner's Tax Deduction (or the like) related to invalid deductions for meals. Misinterpretation of the 9th Amendment to the U.S. Constitution Taxpayer's objection to military spending. Non-negotiable Charge Back - Taxpayer attempts to sell their birthright back to the government for a large dollar amount and requests that a "Treasury Direct Account" be set up to hold the money. Not a Citizen/Free Citizen/Not a Resident of Federal Zone - Taxpayer argues they are not a citizen of the United States and received no income or benefits from sources within the United State. Not a Person or Individual - Taxpayer argues against being a "Person" or "Individual" within the meaning of the IRC; therefore, isn't subject to income taxes. Obscene, Vulgar, Harassing - Taxpayer submits documents or other materials indicating that non-filing is due to dissatisfaction with tax policies or taxation in general. Often this argument is expressed in an extremely demeaning manner with obscene, vulgar, or crude language and characters. ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ Example: ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ Outlandish and/or Unsubstantiated Credits - Taxpayers submit returns and claims that generally reflect income, but also claim the exact amount of income entered as withholding. Oftentimes the filing contains Forms 1099-OID (Original Issue Discount). In some instances, the 1099-OID is shown generated to a payee unrelated to the taxpayer (such as the Department of the Treasury or various judges or attorneys), yet the withholding is claimed on the taxpayer's return. The refunds claimed, resulting from these filings, are large. Prisoners and substitute W-2-- Prisoners supplying a substitute W-2 (Form 4852) with the explanation portion of the Form 4852 stating the income is based on computation of minimum wage for hours worked within the prison. The Form 4852 lists a withholding amount that allegedly represents the amount an employer would withhold from an employee's wages if working for minimum wage. The inmate then claims a refund based on the data for income and withholding they say that the prison should have reported. Prisons never withhold tax from pay and don't issue Form W-2. ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ Services Not Taxable/Thirteenth Amendment/Form of Servitude - Taxpayer argues that income results from the sale of goods; therefore, the value of services isn't taxable. This includes indentured servitude arguments and barter offsets. The taxpayer may also argue that the Thirteenth Amendment outlawed slavery. They may claim to be a "natural enfranchised individual and freeman" who is a resident of a state and therefore a nonresident alien for the purpose of the IRC. Sixteenth Amendment - Taxpayer argues the Sixteenth Amendment wasn't properly ratified; therefore, the federal government doesn't have the legal authority to collect an income tax without apportionment. Taxes are Voluntary/Law doesn't Require - Taxpayer submits a tax return, amended tax return, or correspondence that argues income taxes are voluntary. Thumbprint in lieu of a signature - Thumbprint is present in the signature area on a return. Trusts - Taxpayer attempts to flow income through the trust to avoid personal tax liability. Promoters use "business trusts" as a means of evading income tax. U.S. vs. Long - Taxpayer submits a tax return with zero money amounts and refers to U.S. vs. Long. Unsigned Tax Returns - Taxpayer submits a completed unsigned tax return. A statement why the return isn't signed is attached or added to the return indicating disagreement with the tax system. Unsupportable non-taxable compensation - Taxpayer reports wages but deducts all or a portion of the income as non-taxable compensation. Untaxed - Taxpayer argues that they should be "untaxed" and attempts to drop out of the Social Security system. They withdraw or rescind their SSN, claiming they are a sovereign citizen. Valuation - Taxpayer argues that income isn't taxable because of the declining fair market value of the dollar. They state the dollar isn't backed by gold/silver, or the value of services is offset by the value of the labor (barter income). Wages Deducted in Cost of Goods Sold - Taxpayer submits a return with a Schedule C claiming a deduction equal, or nearly equal, to the amount reported as wage income. The deduction is usually included in the cost of goods sold but could appear under a different deduction category. Wages/Receipts Not Income - Taxpayer argues that salaries and wages are not "income" within the meaning of the Sixteenth Amendment. Taxpayer may also argue that labor worth a certain amount is exchanged for money worth the same amount, so there's no income to be taxed. Wages and other compensation received for the performance of personal services - Taxpayer argues that the wages or other compensation received are not taxable income or are offset by an equivalent deduction for the personal services rendered, including an argument that a taxpayer has a "claim of right" to exclude the cost or value of the taxpayer's labor from income or that taxpayers have a basis in their labor equal to the fair market value of the wages they receive, or similar arguments described as frivolous in Rev. Rul. 2004–29, 2004–1 C.B. 627, or Rev. Rul. 2007–19, 2007–1 C.B. 843. Zero Returns - Taxpayer submits a tax return with zero money amounts and attaches a statement claiming there's no section of the IRC that establishes an income tax liability. The statement may also contain arguments regarding the definition of income. Taxpayer may cite the Latin phrase "Nunc Pro Tunc" ("Then and Now" ) on the return, Form 1096 and/or 1099. Taxpayer may list all zeros and claim a refund of all Federal Withholding, or claim an amount for wages, AGI and Standard Deduction, enter no tax and claim a refund of all Federal Withholding, or taxpayer claims wages and AGI, but carries AGI to refund line. Zero Wages on a Substitute W-2 - Filer generally attaches either a substitute Form W-2, Form 1099, or Form 4852 that shows "$0" wages or no wage information. Entries are usually for Federal income tax withheld but can be Social Security tax withheld or Medicare tax withheld. An explanation on the Form 1040-X or Form 4852 may cite "statutory language behind IRC 3401 and IRC 3121" or include some reference to the company refusing to issue a corrected Form W-2 for fear of IRS retaliation.

# Category A (CAT-A) Criteria Screening

3.11.6.8.15 (07-10-2025) Category A (CAT-A) Criteria Screening To determine if a case meets Category A (CAT-A) criteria, see IRM 21.5.3-2, Examination Criteria (CAT-A) - General, and IRM 21.5.3-3, Examination Criteria (CAT-A) - Credits. The "CAT-A criteria" cited refers to the amount of the tax decrease, credit increase, or certain other changes. If the amended return results in a balance due, or increases the balance, do not send to CAT-A Classification. Only complete claims can be referred to CAT-A. A claim is considered complete if it has all information required to process the return. If processing a superseding return, follow IRM 3.11.6.8.11, Superseding Return Discriminant Function (DIF) Score Screening. Only complete claims can be referred to CAT-A. A claim is considered complete if it has all information required to process the return. If the claim is incomplete, correspond following IRM 3.11.6.11, Correspondence Procedures. Caution: If the response to the correspondence is incomplete, send the claim to CAT-A. When screening a case for CAT-A criteria, ensure the change isolated from any other change on the return meets the criteria listed. If a CAT-A criteria is met and there is an increase to EITC, unless a CAT-A EITC exception is present, screen the case through CC DDBCK. If the case is selected, follow DDBCK Selected procedures in IRM 3.11.6.14.4 (7), CC DDBCK. If the case is not selected, send the case to CAT-A. Don't apply CAT-A criteria to: Combat Zone returns when the TP is actively serving in a Combat Zone. See IRM 3.11.6.17.4, Combat Zone CP notices Credits that are being disallowed Credits that are being reduced below the CAT-A tolerance due to master file or math verification If the case is being forwarded to CAT-A, do not input a TC 971 AC 013. If a dependent's TIN is being changed from an ITIN to SSN, follow IRM 3.11.6.14.1, Revoking a Dependent ITIN, before sending the claim to CAT-A. If the claim meets CAT-A criteria, follow the table. If ... Then ... The CAT-A issue meets SP criteria and the claim is complete Suspend the case to CAT-A. Caution: If Schedule C meets CAT-A criteria and EIC is increasing, input CC DDBCK to check the validation results prior to referring the case to CAT-A. The CAT-A issue doesn't meet SP 1040-X criteria Send to AM as Out of Scope. Follow IRM 3.11.6.10.1, MEFP Reassignment and Reroute Guide, or IRM 3.11.6.10.2, MEFS Reassignment and Reroute Guide, as appropriate. An AUR criteria is present per IRM 3.11.6.8.16, Automated Underreporter (AUR) Screening Send to AUR following IRM 3.11.6.10.1, MEFP Reassignment and Reroute Guide, or IRM 3.11.6.10.2, MEFS Reassignment and Reroute Guide, as appropriate. There's also an out-of-scope issue present on the case Send to AM as Out of Scope. Follow IRM 3.11.6.10.1, MEFP Reassignment and Reroute Guide, or IRM 3.11.6.10.2, MEFS Reassignment and Reroute Guide, as appropriate.

# Automated Underreporter (AUR) Screening

3.11.6.8.16 (01-01-2026) Automated Underreporter (AUR) Screening When working accounts with Automated Underreporter (AUR) involvement, research the account to determine where the account is in the AUR process. This can be determined by reviewing the AUR Process Code (PC) listed under the TC 922 on the account. The status of an AUR case is determined by the last PC posted. Use the table below when determining if the PC meets routing requirements to AUR. Note: The process codes are the two-digit numbers below the TC 922. If the last TC 922 process code is: Then No process code (PC) is shown or any PC not listed below Process as normal. 01, 03, 06, 07, 09-16, 18, 19, 21–25, 27–29, 31, 47–49, 51, 52, 70, 71, 73, 74, or 91-93 Process as normal. 17 or 26 Route as ID Theft. See IRM 3.11.6.8.9, Identity Theft (IDT) Screening. 35, 36, 38, 63–64, 83, or 85 Send the case to Exam per IRM 3.11.6.8.15, Examination Case Screening. 44, 46, 65, 66, 72, 76, 80, 84, 86 Send the case to AM. 30, 34, 55, 57–60, 75, 77–79, 81, 95, 97–98 Send the case to AUR as an open case. 96 If there's an open control to an AUR employee on IDRS, send the case to AUR as an open case. If there's no open control, process as normal. 20, 37, 39, 53, 62, 67–69, 82, 87–90, 94, or 96 and a TC 29X has been input and has one of the following Blocking Series: 050–070, 500–519, 550–589, 600–619, 650–679, or 980–999 Research AMS to determine the AUR issue(s) listed on the CP 2000 or CP 2501 notice. If the amended return is addressing the AUR issue(s), send the case as an AUR reconsideration case. If the amended return isn't addressing the AUR issue(s), process as normal. When AUR identifies an issue(s), a CP 2000 or CP 2501 is sent to the taxpayer and a copy of the notice posts to AMS. The CP 2000 or CP 2501 identifies the specific forms reported to the IRS and not reported by the taxpayer on their tax form. The CP 2000 or CP 2501 also provides the adjustment needed to correct the account and place for the taxpayer to agree or not agree. If the taxpayer does not respond to the CP 2000 or CP 2501, the adjustment is input by AUR. Taxpayers may respond to the notice by filing an amended return either before or after the adjustment has been input. If it can be determined the AUR issue is not being addressed with the amended return, don't route the case to AUR. If AUR rejects the amended return because it's unrelated to their issue, then process the case as normal. Keep in mind the taxpayer will sometimes use their original figures in Column A; don't take this as indication the taxpayer is disagreeing with the AUR adjustment. AUR reconsideration cases must disagree with at least one part of the AUR adjustment as shown on the CP 2000 or CP 2501 to be routed as an AUR reconsideration per (6) below. Taxpayers may indicate disagreement by submitting: An amended return that reduces the income and/or increases credit(s) related to the specific form or issuer as described in the CP 2000 or CP 2501 and adjusted by AUR. This doesn't include cases where the taxpayer is adjusting mitigating factors such as expenses, cost basis, gambling losses or credits not previously claimed and unrelated to the AUR assessment. The CP 2000 or CP 2501 Response Form section disagreement with Option 2. Any statement indicating the taxpayer disagrees with the change that's related to the AUR adjustment, such as "I didn't earn that much." If an AUR case meets CAT-A criteria, don't send the case to CAT-A. The case must be sent to AUR for CAT-A determination. When sending a CII case to AUR, determine the routing destination by using the first two digits of the TC 922 DLN and follow the table below. If processing a ... And the AUR case is ... Then ... MEFP case An open case Follow the table in IRM 3.11.6.10.1, MEFP Reassignment and Reroute Guide, and reroute per the AUR – Open Cases instructions. MEFP case A reconsideration case Follow the table in IRM 3.11.6.10.1, MEFP Reassignment and Reroute Guide, and reroute per the AUR – Reconsideration Cases instructions. MEFS case An open case Caution: If the return is in the "Attached Files" and not in the "Document Images" section of the CII case, follow the MEFP instructions above. Follow the table in . IRM 3.11.6.10.2, MEFS Reassignment and Reroute Guide, and reroute per the AUR – Open Cases instructions. MEFS case A reconsideration case Caution: If the return is in the "Attached Files" and not in the "Document Images" section of the CII case, follow the MEFP instructions above.

# AM Case Screening

3.11.6.8.17 (01-02-2024) AM Case Screening Cases are sent to AM based on the issue, the dollar tolerance, IDRS conditions, and other various reasons. A TC 150 must be posted before sending a case to AM, unless specific instructions are provided. Don't input a TC 971 AC 010 when routing a case to AM. If there's an open case to AM, send the case to AM. Send cases to AM for a Manual Refund if: The taxpayer requests the refund issued in a name other than shown on master file. The taxpayer requests the refund issued to a temporary address. Refund is less than one dollar. Refund is $10 million or more. SP 1040-X tax examiners process cases using CII, and during processing, CII imaged returns might be generated. Use the table below to determine how to process CII imaged returns: If the CII image originated from... Then ... Another area Send the case to AM. Exception: If a CII imaged return is notated "Process as Original (PAO)" or similar verbiage and there's not a TC 150 posted or pending, then send the case to Batching. When needed, use the Prior Year and Conversion Form 1040 Edit Sheet for Tax Year YYYY. If the case is for the current year and the conversion form isn't available, then "dummy" a current year Form 1040 for processing. SP 1040-X Process following normal procedures.

# Open Case and Open Control Base Screening

3.11.6.8.18 (02-06-2024) Open Case and Open Control Base Screening Generally, if an account has an open control base on CC TXMOD you'll send the return to the assigned employee or a specified department. An open case can be in any of the following status: "A" Active; "B" Background; "S" Suspense; or "M" Monitor. Note: Don't route cases that are open in CC ENMOD. Cases in A or S status must be routed based on the ASSIGN-TO field of the open control. Don't send cases open in B or M status; continue to process if routing criteria isn't present. The following exceptions apply to A, B, S, and M status: If the open control is in B status due to a P- freeze/TC 841 and the case is a net refund, then send the case to AM. Refer cases with a category code NLUN to the assigned IDRS number to process. Cases open to AM must be sent to AM. See (7) below to identify AM cases, more AM routing criteria might be identified through research found in (6) below. For cases open to a 1040X SP employee see IRM 3.11.6.8.18.1, Cases Open to an SP 1040-X Tax Examiner. Cases open to RIVO AQC or QRPA must be screened following IRM 3.11.6.8.14, Return Integrity and Verification Operation (RIVO) Screening. For cases that are processable place the case in B status, input the adjustment, and then return it to its original status. Cases with Activity 9465 must be placed in "B" status and processed. Cases controlled to Appeals IDRS number 66XXX, send the case to AM. AUR controlled cases must be screened following IRM 3.11.6.8.16, Automated Underreporter (AUR) Screening. Open case controls with a category code "ST04" or "-X04" must be screened following IRM 3.11.6.8.10, Statute Review Screening, and IRM 3.11.6.17.1, Processing Statute Cases. Exception: If processing a return that's not a statute year, follow IRM 3.11.6.17.1, Processing Statute Cases, paragraph 1f. If the open control is assigned to your current or previous IDRS number, close your open control before continuing to take any action on the return. Use CC MESSG or the IDRS Unit and USR Database, IUUD, web site to determine the appropriate campus location and stop number based on the IDRS number in the ASSIGN-TO field of the open control. Note: If unable to locate the stop number, see your lead. The AM IDRS numbers are identified by the service center two-digit code and 301-399 series. For instance, a Customer Service Representative (CSR) in Kansas City would be 093XX. Submission Processing 1040X Units use the SC code and the 200-244 series. This includes cases open to the AM suspense queue that don't contain 301-399 series: Campus Generic IDRS number Atlanta 0739900025 Andover 0848900000 Austin 0686100000 Brookhaven 0138640000 Cincinnati 0237500000 Fresno 1042000000 Kansas City 0938000000 Reminder: This number is also used by SP 1040-X.

# Cases Open to an SP 1040-X Tax Examiner

3.11.6.8.18.1 (01-02-2024) Cases Open to an SP 1040-X Tax Examiner If there's a CII case open to another 1040-X SP tax examiner (TE) for the same tax year, reassign the case to the SP 1040-X TE with the oldest case control. If the other open case is in suspense to a SP 1040-X TE, refer your case to your lead or manager. The lead or manager must ensure the case in suspense is the oldest case. If the case in suspense is the oldest case, the lead or manager must take the following action: a. Enter a case note that states, "Case reassigned to TE with the oldest case control." b. Reassign the case to the TE with the oldest case. Note: When using the CII auto-distribution function, cases for the same taxpayer are sent to the same TE. Ensure all open controls associated with the case(s) that you're processing are closed. Associated cases are those that have an: Open control to your local 1040-X department Open XRET control base with an Activity that has a "SPX" designation and is assigned to a SP 1040-X employee or SP 1040-X queue Example: An Austin TE is working a MEFS case and notices there are two open controls. One of the open controls is for the MEFS case being worked, and the other is an XRET control assigned to the Kansas City generic queue. See Figure 3.11.6-1, The XRET Control and Open CII Case Match.

# Updating Taxpayer Information Using CC ENMOD

3.11.6.13 (01-02-2024) Updating Taxpayer Information Using CC ENMOD This subsection provides information on changes made to FS, Schedule LEP, Request for Change in Language Preference, and Form 9000, Alternative Media Preference. Evaluate each situation to determine when to adjust a taxpayer's FS, language and alternative media preference.

# Entity Changes

3.11.6.13.1 (07-22-2024) Entity Changes If the taxpayer requests their refund be issued in a name or address other than the one shown on the adjustment, send the case to AM per IRM 3.11.6.8.17, AM Case Screening. When making any Entity changes, input the change on IDRS using CC ENREQ to generate the CC INCHG screen. A signature (both if MFJ) is required before an address change can be input. If signature correspondence is required, use the address of record. Exception: A signature isn't required on an undelivered mail piece with an affixed USPS yellow label. Follow IRM 3.11.6.13.1.1 (3), Address Changes. Don't update the Entity section if an adjustment isn't being input or the return is being sent to another area. Input a posting delay code on any adjustment when making any changes to the taxpayer's address or name line information. If there's a pending change that affects the return you're processing, input a posting delay code. Follow the instructions in the table below when a name change is requested: If ... Then ... Taxpayer files a Form 1040-X to indicate a name change only Check CC INOLE for NEW SSA/NC or SSA: If the name control on Form 1040-X matches the "NEW" SSA/NC or SSA, input TC 290 .00 and close the CII case. Don't update the name. If the name control on Form 1040-X doesn't match the "NEW" SSA/NC or SSA, route the return to Entity with the following notation in the comments section of the routing slip: "Name change request -- don't process 1040-X." Taxpayer files a Form 1040-X to indicate a name change and tax changes are also required Check CC INOLE for NEW SSA/NC or SSA: If name control on Form 1040-X matches the "NEW" SSA/NC or SSA, continue to process the return, if no route out criteria is present. Don't update the name. If the name control on Form 1040-X doesn't match the "NEW" SSA/NC or SSA, send the case to AM. Note: Taxpayers sometimes use variations of their first name, including using initials when filing original (verification is performed by matching the name control to the SSN) and amended returns This isn't considered an indication of a name change unless the taxpayer is specifically asking for a name change. If the taxpayer is requesting to change the name the table above would be followed. Exception: Input name change only if there's a clear indication that the name was transcribed incorrectly (e.g., ANDERSON transcribed as ANDESON).

# Address Changes

3.11.6.13.1.1 (03-13-2024) Address Changes Don't update the address if an address change has posted after the Form 1040-X received date. Use CC ENMOD to verify cycle date. If the 1040-X is received in the same cycle that an address change has posted then update the address to the address on the 1040-X. If the address on the 1040-X doesn't match CC ENMOD or one of the conditions below applies, update the address. Taxpayer alters the address in the Entity of the Form 1040-X or on a CP notice. Taxpayer specifically indicates in the Explanation of Changes. Taxpayer attaches a separate sheet or Form 8822 requesting the address change. Note: If working a Form W-7 to reactivate an ITIN, see IRM 3.11.6.17.14.1, Returns Received From the ITIN Unit (Form W-7). Upon receipt of any undelivered mail piece with an affixed USPS yellow label, research and update the address following the table. If the case you're working doesn't fall into one of the issues in table, don't update the address. Exception: An address on a yellow label becomes the taxpayer's last known address unless taxpayer provides clear and concise notification of a change of address, or the Service properly processes a taxpayer's federal income tax return with a different address per paragraph 2 above. If the taxpayer's ... And ... Then ... Name printed in the letter What is shown on the "yellow label" are exactly the same Update the taxpayer address to the "yellow label" address. Mailing address differs from the "yellow label" The name printed on the "yellow label" is an exact match to the correspondence Update the taxpayer's mailing address to the "yellow label" address. Then reissue the correspondence to the taxpayer's updated mailing address. First name is similar to the one on the "yellow label" The last name is an exact match Confirm whether IRS records show any other taxpayers with similar first names and the exact same last name at the same address. If not, update the taxpayer address. Otherwise, don't update the taxpayer address. If both a PO Box and a street address are present on Form 1040-X, input the PO Box on the address line and the street address on the continuation of the name line. If the city and zip code differ between the PO Box and the other address listed use the city and zip code of the PO box. The In-Care-Of (C/O) is considered part of the address. If the entity information on IDRS shows an In-Care-Of person, but the amended return doesn't, update the Entity on IDRS and vice-versa. Use CC INCHG field "CONTINUATION-OF-PRIMARY NAME" to update In-Care-Of information. If the address on the amended return appears incomplete, research the return packet for the missing information or use www.USPS.com to verify the address. For address changes on multiple year returns from the same taxpayer, use the address on the most current return. If the taxpayer used Form 1040-X instead of Form 8822 to inform us of an address change and there's no tax adjustment, update the address and process the return by inputting a TC 290 .00, RC 099, SC 1. When Form 8822 is attached and the Form 1040-X is being routed, detach Form 8822, send the case to Entity.

# Filing Status Changes

3.11.6.13.1.2 (09-04-2024) Filing Status Changes If a Form 1040-X is received requesting a FS change, and a TC 971 AC 137 is present on the module, send the case to AM. SP won't adjust an account when both taxpayers previously filed a MFS, single, or HoH return and are now filing MFJ. These cases require backing out tax information or merging accounts. Send to AM. Use the following chart when making a FS change: If the taxpayer changes the FS on Form 1040-X ... And ... Then ... From FS 0 Update the FS based on Form 1040-X. To FS 1 (Single) Update INCHG to FS 1. Use RC 001. To FS 2 (MFJ) Update INCHG to FS 2. Use RC 002. See IRM 3.11.6.13.1.2.1, Filing Status 2 Changes. From FS 2 (MFJ) Send the case to AM. To FS 3 (MFS) From FS 1, FS 4, or FS 5 Update INCHG to FS 3. Use RC 003. Enter the spouse's SSN if known. Note: When changing to FS 3, review credit eligibility requirements and take appropriate action. From FS 3 (MFS) Changing to FS 1, FS 4, or FS 5 The spouse's SSN field may populate with 000-00-0001. This action removes the cross-reference and mustn't be altered. When manually changing from FS 3, input the spouse's SSN following this example. From FS 3 (MFS) Changing to FS 2 Send the case to AM. To FS 4 (HoH) The taxpayer is claiming a dependent or non-dependent and the dependent's name or TIN is missing or doesn't match. Correspond per IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins.

To FS 4 (HoH) The taxpayer is claiming A non-dependent (name and QND are provided or claimed for EIC) Update INCHG to FS 4. Use RC 004. To FS 5 (QSS) Update INCHG to FS 5. Use RC 005. To FS 6 MFS return and spouse isn't required to file a return and spouse exemption is claimed Send the case to AM. From FS 7 Update the FS based on Form 1040-X.

# Filing Status 2 Changes

3.11.6.13.1.2.1 (01-02-2024) Filing Status 2 Changes For FS 2 (MFJ) changes, research for a TC 150 on both the primary and secondary taxpayer's account. Use CC NAME to verify the taxpayer has not previously filed under a different TIN for the tax year that you're working. If both taxpayers have a TC 150 posted, send the case to AM. Note: If the spouse's account is set up on the invalid segment of master file (an asterisk after the TIN (000-00-0000*), send the case to AM. For the tax year you're working, if one spouse didn't previously file a return, adjust the established account of the taxpayer that has filed, to reflect the amended joint return. Exception: If the non-filed taxpayer has income that exceeds the exemption amount in IRM 3.11.6.14, Personal Exemption or Dependent Change, and the ASED is less than one year from the IRS Received Date, then send the case to AM. Send the case to AM if any of the following conditions apply to the account of the taxpayer who didn't previously file: If a TC 140 is present If a TC 460 is present If an E- freeze is present Any available credit or payments requiring a transfer to the primary account Note: When researching spouse, search for ID Theft markers. See IRM 3.11.6.8.9, Identity Theft (IDT) Screening. When adding a spouse, perform thorough research, to verify spouse's name and TIN using IDRS and attachments. If a TIN is obviously inappropriate, for example (111-11-1111) or (123-45-6789) or a similar TIN configuration, missing, incorrect, or illegible, see IRM 3.11.6.5.4, Taxpayer Identification Number (TIN). When the taxpayer adds a spouse that has an ITIN, research CC INOLE for the current ITIN status. See IRM 3.11.6.17.14.2, ITIN Status, for processing instructions. If the spouse is changing from an ITIN to a valid SSN, send the case to AM. See IRM 3.11.6.5.4, Taxpayer Identification Number (TIN). When editing (adding, replacing, changing, and/or deleting) a spouse, update the DUPOL database using CC DDBCK to correct the FS and the secondary's information (including EX/DP and Education Credit, if applicable). When DDBCK isn't available use CC DUPED. See IRM 3.11.6.14.5, CC DUPED. Exception: If the only change is a FS change to FS 2, and no credits are being claimed for the spouse, don't update the DUPOL database. The Form 1040 has two separate lines available for taxpayers to use when filing jointly, master file contains only one primary name line. There are 35-character spaces available for both taxpayer names. The bracket "]" is interpreted as a space. Don't use the second line as a continuation of the name line. The entering of two brackets around the PRIMARY taxpayer's last name is required when the SECONDARY taxpayer's last name is different than the primary taxpayer's last name. Don't input an additional space before or after the bracket when entering taxpayer names. The ampersand (&) indicates a break in joint filers' names. The correct methods to input name changes are shown below: The italicized print indicates the primary taxpayer's name control. Tax Return Input Format for Joint Filers John Owl Mary Owl John & Mary]Owl John Owl Mary Shark John]Owl]& Mary Shark John Owl Mary Shark-Owl John]Owl]& Mary Shark-Owl John D Owl Mary Ann Shark- Owl John D]Owl]& Mary Ann Shark-Owl John D Owl III MaryAnn L Shark John D]Owl]III & MaryAnn L Shark John D Owl Jr MaryAnn L Owl John D Jr & MaryAnn L]Owl MaryAnn L Owl John D Owl Jr MaryAnn L & John D]Owl]Jr Before shortening any taxpayer name(s), all necessary research must be conducted (i.e., CC INOLE, CC RTVUE, CC IMFOL, CC NAMES, CC NAMEI) under both segments of the master file. When taxpayers file jointly and it's necessary to reduce the taxpayers' Name Lines or Name Controls, it's important to retain the first four characters of the secondary taxpayer's surname. If the primary and secondary name(s) exceeds the 35-character space limit, use the following instructions, in the order presented, to correctly reduce the length of the taxpayer's name: Substitute the appropriate initial for the secondary taxpayer's middle name Delete middle initial of secondary taxpayer Substitute the appropriate initial for the primary taxpayer's middle name Delete middle initial of primary taxpayer Substitute the appropriate initial for the secondary taxpayer's first name Substitute the appropriate initial for the primary taxpayer's first name Substitute the appropriate initials for both the primary and secondary taxpayers' first name(s) if their last name(s) total characters exceed the 35-character spaces limit Abbreviate the secondary taxpayer's surname. Abbreviate the surname by removing the vowels (begin with the vowels at the end of the secondary taxpayer's surname first) Example: Clydesdale becomes Clydesdal or Clydesdl or Clydsdl (if necessary) Abbreviate the primary taxpayer's surname as the last step. Abbreviate the surname by removing the vowels (begin with the vowels in the end of the primary taxpayer's surname) Example: Appaloosa becomes Appaloos or Appalos or Appals (if necessary).

If a TIN is obviously inappropriate, for example (111-11-1111) or (123-45-6789) or a similar TIN configuration, correspond for the correct TIN per IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins. If ... and ... Then ... The TIN and Name Control (NC) match any of the CC INOLE information or CC DDBKD The TIN was timely assigned, and the ITIN status (if needed) is active Allow the dependent, adjust the account, and update CC DDBCK. The TIN and NC don't match any of the CC INOLE information or CC DDBKD, use the IAT Name Search tool for the correct TIN and NC The correct TIN and NC are found Follow the instructions in the box above. The TIN and NC don't match any of the CC INOLE information or CC DDBKD, use the IAT Name Search tool for the correct TIN and NC The correct TIN and NC are not found Correspond IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins. Exception: When working returns received from the ITIN department, see IRM 3.11.6.17.14.1, Returns Received From the ITIN Unit (Form W-7). The taxpayer states they could not obtain a TIN because a child was born and died in the same tax year The taxpayer provides any of the following documentation: Birth certificate Death certificate Doctor/midwife statement on letterhead with business address and telephone number Copies of hospital medical records Process as normal. Note: Don't update the DUPOL database. The taxpayer states they could not obtain a TIN because a child was born and died in the same tax year If the taxpayer has not provided the required documentation Input a corrected adjustment per IRM 3.11.6.17.5, Inputting a Corrected Adjustment, and correspond per IRM 3.11.6.11.11, Correspondence for Dependent Documentation (Letter 3050C). If the taxpayer attempts to add a dependent that will be born in a future year or that died in a prior year, see IRM 3.11.6.17.5, Inputting a Corrected Adjustment. Use fill-in: We didn't add your dependent as requested based on the dependent's date of birth or date of death. If the taxpayer is adding, replacing, changing, or deleting a dependent and you can't determine the correct dependent or it is unclear, correspond per IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins. Exception: In a situation in which the dependent(s) being added has a rejected ITIN and therefore won't have an SSN, see the instructions per IRM 3.11.6.17.14.1, Returns Received From the ITIN Unit (Form W-7). When adding, replacing, changing, or deleting dependents, see IRM 3.11.6.14.3, Updating the DUPOL Database. For amended returns or claims in which the taxpayer is removing exemptions or dependents, remove any associated credits. If the dependent previously had an ITIN and now has a valid SSN, follow IRM 3.11.6.14.1, Revoking a Dependent ITIN.

# Revoking a Dependent ITIN

3.11.6.14.1 (01-02-2024) Revoking a Dependent ITIN If a dependent's TIN is being changed from an ITIN to SSN, the ITIN must be revoked. To revoke the ITIN, prepare Form 4442 and send it to the Austin ITIN Unit. Form 4442, Part III, Section B, must have the following statements: Revoke ITIN (insert the ITIN of the dependent being revoked). New SSN is (insert the dependent's new SSN). The dependent's name is (insert the dependent's name) and D.O.B. is (MMDDYYYY). Reason: The dependent now has a valid SSN. See reference: IRM 3.11.6.14, Dependent Changes Request for dependent - Merge Not Needed Update the DUPOL database.

# Form 8332, Release of Claim to Exemption for Child of Divorced or Separated Parents

3.11.6.14.2 (01-01-2026) Form 8332, Release of Claim to Exemption for Child of Divorced or Separated Parents Send the case to AM if the taxpayer submits a copy of their divorce decree with, or without, Form 2120, Multiple Support Declaration, and doesn't submit Form 8332, Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent. For TY 2018 and later, Form 8332, Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent, is used for dependent credit documentation. When a non-custodial parent claims a child as a dependent who didn't live with them under the rules for children of divorced or separated parents, the taxpayer indicates this by: Attaching Form 8332, Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent, or similar statement Entering an amount on Form 1040-X, page 2, Part I, line 26, Your dependent children who didn't live with you due to divorce or separation Listing the child on Form 1040-X, page 2, Part 1, line 30, List ALL dependents (children or others) claimed on this amended return Notating in Part III, Explanation of Changes, area of the Form 1040-X Reminder: Review IRM 3.11.6.14, Dependent Changes.

If missing, correspond per IRM 3.11.6.12, Correspondence Table of Issues, C-Letters and Paragraph Fill-ins. Update the DUPOL database.

# Updating the DUPOL Database

3.11.6.14.3 (07-22-2024) Updating the DUPOL Database The DUPOL database contains tax return information for the current and two prior tax processing years and provides duplicate SSN data for research purposes. Submission Processing is responsible for updating the DUPOL database when editing (adding, replacing, changing, or deleting) records. Use CC DDBCK unless specifically instructed to use CC DUPED. If instructed to use CC DUPED, update for current year only. If it is a prior year, don't update the DUPOL database, continue processing the return. When adding a credit or dependent requiring TIN validation, always use CC INOLE or CC DDBKD to verify the TIN, NAME, and date of birth (DOB) prior to updating the DUPOL database. When deleting a dependent, verify the taxpayer is removing credits associated with the dependent. The credits received on behalf of each dependent are listed on the CC DDBCK screen. The taxpayer should remove all CTC, ACTC, ODC, Education Credits, and Adoption Credit that were received based on the dependent. The taxpayer may qualify for the EITC and Child and Dependent Care Credit in special circumstances. If the taxpayer didn't remove CTC, ACTC, ODC, and Education Credits, you must reverse the credit(s) and input a corrected adjustment following procedures in IRM 3.11.6.17.5, Inputting a Corrected Adjustment. If the taxpayer claimed Adoption Credit, send the case to AM. When the taxpayer is changing to FS 3, follow IRM 3.11.6.13.1.2, Filing Status Changes. Send the case to AM if the account has been merged or resequenced and an update to the DUPOL database is required. Use the following chart for determining when/if to update the DUPOL database: If ... Then ... Taxpayer is adding or removing: An exemption for primary or secondary taxpayer Reminder: If the only change is a FS change to FS 2, and no credits are being claimed for the spouse, don't update the DUPOL database. A dependent Earned Income Credit (for dependents), see IRM 21.5.3-3, Examination Criteria (CAT-A) - Credits. EIC increase due to changes in income other than Form W-2, see IRM 21.5.3-3, Examination Criteria (CAT-A) - Credits. Child and Dependent Care Credit Education Credit Child Tax Credit Additional Child Tax Credit when the qualifying dependent is eligible for CTC, but can't be claimed on line 7 Credit reduced to zero EITC TIN-related Math Errors, see IRM 21.5.3-3, Examination Criteria (CAT-A) - Credits.

# CC DDBCK

3.11.6.14.4 (07-22-2024) CC DDBCK The CC DDBCK is used to update the DUPOL database which is used for validating dependents and certain credits. CC DDBCK can be updated for the current tax year and two years prior. DDBCK checks: If the TIN or Name Control doesn't match INOLE data If child is deceased or doesn't meet the age criteria to qualify the taxpayer for a credit If a DDB rule is broken If DUPTIN database indicates a duplicate use of a TIN When updating DDBCK, use the primary's TIN of the return. It displays the dependents and qualifying children from the original posted return or as last modified. When updating dependent and/or credit information, CC DDBCK must be used prior to inputting an adjustment. When working EITC TIN-Related Math Error responses, overlay the YYYYMMDD on the CC DDBCK Return Summary Screen, under Change Dates, with the received date of the Form 1040-X. When required to update CC DDBCK, use the following chart. If ... and ... Then Use ... EITC is decreasing or isn't involved Dependent and/or spouse is being changed, added, deleted Reminder: If the only change is a FS change to FS 2, and no credits are being claimed for the spouse, don't update the DUPOL database. or there's an increase to ACTC and/or AOTC Note: For 2018 - 2025 amended returns or claims in which the taxpayer is trying to change exemption(s), see IRM 3.11.6.14, Dependent Changes.

OK to input ADJ54, if eligibility met Input the adjustment following the appropriate procedures. OK to input ADJ54 if eligibility met, enter RC 103 Send the case to AM. RC 103 indicates that taxpayer is part of the EITC certification program. RECERT IND Send the case to AM. Date Older Than 18 Months DDBCK won't allow an entry 18 months or later. Overlay the pre-populated date with the received date of the return. Date Can't be a Future Date If working a current processing year claim that is timely filed prior to April 15, use the current date for the input. Date Earlier than Return If working a current processing year claim that is timely filed prior to April 15, use the TC 150 date. Note: If DDBCK won't accept the TC 150 date, use the current date for the input. If the response to either the initial DDBCK screen or validation results screen displays "Selected " or "Send As CAT-A" , follow the table below: If the DDBCK response is ... Then ... "SELECTED DDBCK REROUTE TO EITC" Return to the "Active Case" page in CII. Capture the DDBCK response screen. Input a TC 971 AC 013 In the "Actions" section, select" send the case to EITC" from the drop-down list and click "GO" . On the "send the case to EITC" page in the "TO:" field, choose EITC Selected for your Campus. "SELECTED DDBCK REROUTE TO EITC XXXX" Return to the "Active Case" page in CII. Capture the DDBCK response screen. Input a TC 971 AC 013 In the "Actions" section, select" send the case to EITC" from the drop-down list and click "GO" . On the "send the case to EITC" page in the "TO:" field, choose EITC Selected for your Campus indicated in the response. "SEND AS CAT A" Return to the "Active case page" in CII. Capture the DDBCK response screen. Suspend to CAT-A. On CC DDBCK "Selected" cases, a TC 424 is generated automatically in IDRS and places a -L freeze on the account. If DDBCK is updated in error, the input must be deleted to prevent an erroneous case from opening in Exam. On "Follow IRM" cases, you must use the appropriate subsection of IRM 3.11.6 to process the amended return. If the DDBCK validation passes, and the case isn't selected for Exam or CAT-A, DDBCK updates DUPTIN/DUPOL to reflect any changes that were entered. If the TIN or name control entered failed validation, DUPTIN won't be updated. Instead, the CC displays a prompt "PROCESS UPDATES (Y/N)?" and waits for the user to respond before continuing. If the validation error is caused by data entry error, the fields can be corrected. When corrections are made and retransmitted, DDBCK validates the input again from the beginning. Note: If the DDBCK response states that the child failed validation (other than an invalid TIN/Name issue), refer to AM. See IRM 3.11.6.15.4, Earned Income Credit (EIC) - Line 14.

# CC DUPED

3.11.6.14.5 (01-02-2024) CC DUPED The CC DUPED allows users to edit and correct information contained in the DUPOL database which is used for TIN validation. Only update the DUPOL database for a current tax year return after the name and TIN have been verified using CC INOLE. When a dependent, EITC, or a credit requiring TIN validation for allowance is being changed, use CC DUPED to update the TIN database (DUPOL). If the amount of a "TIN related" credit is changed because of an income change and there's no change to the TIN, you would not use CC DUPED. See (3) for additional conditions. Don't update CC DUPED if the only reason for the update is: Claiming EITC for self or spouse only A FS change, which doesn't affect dependents/credit allowance Reminder: If the only change is a FS change to FS 2, and no credits are being claimed for the spouse, don't update DUPOL database. If the taxpayer doesn't provide the TIN of the dependent being removed, research RTVUE. If found, update the DUPOL database. The display screen allows users to find the exact record they want to modify. A record number is shown for each record that can be edited. CC DUPED procedures apply only to the current tax year return. The TIN SOURCE CD field on the edit screen has been expanded to three positions to allow adding and changing of multiple records. To change multiple records for the same TIN from a single return, bring up the change screen for the record. You can then enter two additional TIN SOURCE codes and all three will be changed at the same time. CC DUPED doesn't replace master file account action and should be updated in addition to any MF adjustment required. Don't disclose DUPED data. Taxpayers are not entitled to know who has claimed them, their dependents, or EITC. If the taxpayer clearly indicates who'll be claiming the dependent, don't update the other account based on this information.

# Add a Record

3.11.6.14.5.1 (01-01-2026) Add a Record Add a Record is used when adding a dependent, spouse (secondary TIN) or to add a new Form 2441 credit, Form 8863 and/or Schedule EIC. To add the record, Enter "A" in the "REQUEST TYPE" field. When the edit screen is displayed, enter the record information on the edit screen and then transmit. Name Control - Enter the name control of the dependent being added. Primary SSN on return - Enter the Primary TIN from Form 1040-X. Service Center CD - Enter the two-digit File Location Code from the TC 150 DLN for the processing center where the taxpayer originally filed. The Edit Screen provides Processing Codes for ELF (Electronic Filing System). Use ELF codes only if appropriate. (Refer to Doc 6209 FLCs for a list of valid File Location Codes). Filing Status - Enter the "Amended return FS" from Form 1040-X. Dependent Status Ind - Enter "0" to indicate the dependent can't be claimed on another return. - "0 " – Indicates the dependent can't be claimed on another return - "1 " – Used only when the dependent is claimed on another return TIN Source CD - Enter how the TIN is being applied during this action. This is a required entry. "P" = Primary "S" = Secondary "D" = Dependent "B" = Form 2441, Child and Dependent Care Expenses "C" = Form 8863, Education Credit "E" = EITC, Earned Income Tax Credit When the information is transmitted, the DUPED response screen is displayed to show the updated information. Note: Continue to process the return if the message "DUPLICATE USE OF SSN" is displayed after transmitting. This is an indication the added dependent is already being claimed by a different taxpayer, but a soft notice addressing the issue is generated automatically.

# Change a Record

3.11.6.14.5.2 (01-01-2026) Change a Record Change a Record is used to update the dependent status indicator if a primary taxpayer is adding or removing their own exemption. To change a record, use CC DUPED, without a definer, and the TIN of the person being claimed to display all the records for that TIN. Exception: Don't update the DUPOL database on invalid primary or secondary TINs. Send the case to AM. Enter a "C" in the request type field and the record number in the record number field and then transmit. This is equivalent to entering a CC DUPED with the definer "C" and the record number in line "1" of the CC. When the edit screen is displayed, enter the appropriate corrected information and then transmit. Name Control (N/C) - Enter the name control of the dependent/exemption being changed. Filing Status - If the FS is changing, enter the appropriate code. Dependent Status Ind - Enter "1" to indicate the exemption is claimed on another return or enter a "0" to indicate the primary taxpayer is claiming a personal exemption. If you delete a record, the response is shown with a dash under REC NUM and the Julian date in the REV DATE column. If we "Change a record" , the response shows a Record Number (REC NUM) and under column "DEP STAT IND" shows the change. Note: Multiple taxpayers may have claimed the same exemption or credit. Only change the records that relate to the account you're working.

# Delete a Record

3.11.6.14.5.3 (11-21-2019) Delete a Record Delete a Record is used when any of the following are removed or when a credit is reduced to zero: Dependents Schedule EIC, Earned Income Credit Form 2441, Child and Dependent Care Expenses Form 8863, Education Credits When deleting a record, use CC DUPED with the TIN of the dependent for which the action is being taken. Delete records that you created in error. Enter a "D" in the "REQUEST TYPE" and the appropriate record number in the "RECORD NUMBER" field and then transmit. This is equivalent to entering a DUPED with the definer "D" and the record number in line "1" of the CC. The edit screen is displayed along with a delete confirmation message. Enter "Y" to delete the record, and then transmit. When the information is transmitted the display screen shows with the corrected information.

# Specific IMF Adjustments

3.11.6.15 (07-22-2024) Specific IMF Adjustments The following subsections contain procedures for processing the Form 1040-X: Income and Deductions - Line 1, Adjusted Gross Income - Line 2, Itemized or Standard Deductions - Line 4a, Reserved for future use - Line 4b, Qualified Business Income Deduction - Line 5, Taxable Income Tax Liability - Line 6, Tax (may include ACA) - Line 7, Credits (non-refundable) - Line 9, Reserved for future use - Line 10, Other Taxes (Form 5329/1099R and Self-Employment (SE) Tax) - Line 11, Total Tax Payments - Line 12, Federal Income Tax Withheld and Excess Social Security and Tier 1 RRTA Tax Withheld - Line 13, Estimated Tax Payments - Line 14, Earned Income Credit (EIC) - Line 15, Refundable Credits Refund or amount You Owe - Line 23, Credit Elect All credits require that the primary taxpayer, secondary taxpayer, and the qualifying child(ren) have a valid TIN. See IRM 3.11.6.5.4.2, TIN Requirements for Dependents and Credits. Note: An Internal Revenue Service Number (IRSN) isn't a valid TIN for credit allowance. An IRSN can be identified as beginning with a "9" with the 4th and 5th digits being a campus code. If the credit requires a qualifying child, use CC INOLE to verify the name control, TIN, date of birth, and date of death of the qualifying child. If the Child and Dependent Care Credit, CTC, ODC, EITC, Adoption Credit and/or Education Credit is being claimed for a TIN for which our records indicate a date of death prior to the tax year, send the case to AM. The AOTC, ACTC, CTC, ODC, and the EITC have specific TIN requirements. See each individual subsection and IRM 3.11.6.5.4.2, TIN requirements for Exemptions and Credits. When inputting an adjustment and there are more Item Reference Numbers (IRN) or Credit Reference Numbers (CRN) than fields available, input the adjustment as follows: Note: If xMend is used, allow xMend to input the two adjustments. Input changes from lines 11 - 15.

# Income and Deductions Line 1 through Line 5

3.11.6.15.1 (01-03-2023) Income and Deductions Line 1 through Line 5 Income and adjustments to income and deductions to income are covered in this subsection. Income and adjustments to income are reported on Form 1040 or Schedule 1, Additional Income and Adjustments to Income.

# Adjusted Gross Income (AGI) - (Line 1)

3.11.6.15.1.1 (07-22-2024) Adjusted Gross Income (AGI) - (Line 1) Any adjustments to income or deductions to income are reported on line 1 of Form 1040-X, Amended U.S. Individual Income Tax Return. If there's indication that a taxpayer received wages from ministerial duties, is a minister, or Form 4361, Application for Exemption From Self-Employment Tax for Use by Ministers, Members of Religious Orders and Christian Science Practitioners, is attached, then send the case to AM. If the taxpayer indicates they made a Qualified Charitable Distribution, "QCD" , refer the case to your lead. The lead must screen the case through the Interactive Tax Law Assistant, ITLA, on SERP. Use IRN 888 for any positive or negative change to AGI. Note: The AGI can be a negative number or be reduced below zero.

# Earned Income

3.11.6.15.1.1.1 (09-04-2024) Earned Income Earned income includes all employee compensation subject to income tax, net earnings from self-employment (SE), and gross income received by a statutory employee. Taxable earned income includes: Wages Salaries Tips Strike pay, other than bona fide gifts Sick pay Union strike benefits Net earnings from self-employment (SE) or gross income received by a statutory employee. Disability benefits (not disability Social Security) received by taxpayers under minimum retirement age (normally, this is reported on the Form 1040 as wages). Note: Minimum retirement age may vary. An amount paid to an inmate in a penal institution, for work, isn't considered earned income for EITC purposes. Refer to IRM 3.11.6.17.17, Prisoner Returns. For EITC purposes, use SE income as reported on Schedule SE, minus the deductible part of SE tax or use EIC Worksheet B in Publication 596, Earned Income Credit. If Schedule SE isn't present because the net earnings from self-employment shown on Schedule C, C-EZ, or F (or the combined net earnings) ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡, use the amount of net profit or loss reported on Schedule C, C-EZ or F. If Schedule SE isn't present and there's a change to income that appears to be from self-employment earnings, screen the case for CAT-A criteria. If SE income is a loss, subtract the amount from other earned income. If the optional method is used, use the optional amount as income; don't subtract the SE loss. If the taxpayer is a statutory employee (indicated on Form W-2, box 13), use Schedule C or C-EZ, line 1, as earned income. Note: If taxpayer receives wages from ministerial duties, some of the income reported on Form 1040, line 7, may also be shown on Schedule SE, line 2. Send the case to AM.

A special rule applies for certain taxpayers affected by the disasters shown below. Qualified individuals whose earned income for the applicable tax year is less than the earned income in the preceding taxable year may elect to use their preceding taxable year earned income when figuring EITC. Taxpayers must enter "PYEI," and the dollar amount of the prior year earned income on the dotted line for EITC. The main home of qualified individuals must have been in: A federally declared disaster that occurred in 2018 or 2019, but before December 21, 2019. A federally declared disaster that occurred beginning January 1, 2020, but before February 26, 2021 Hurricane Ida disaster after August 28, 2021 Note: Verify the taxpayer was in the qualified disaster area via the IRS Disaster Assistance Program.

SP is now working TIN related math errors. TIN related math error codes include 604, 610, 605, 654, 667, 701, 702, 741, 743, 745 and 748. Note: If the DDBCK response states that the child failed validation (other than an invalid TIN/Name issue), send the case to AM. When making an adjustment to the EITC: RC 053 CRN 764 for increases CRN 765 for decreases Note: Priority code ''8'' is required when a TC 764 is input with TC 29X and there's a prior posted TC 29X (except a previously posted TC 290 with priority code 6 or a TC 290 with Julian Date 999). Use priority code ''1'' if both priority code ''1'' and ''8'' are required to adjust the account. Example: An account with a -L freeze that's processable and the conditions above would require priority codes ''1'' and ''8'' and therefore ''1'' would be used.

There's never a situation where the posting delay code is greater than "1" on MFT 35. PDCs are applicable for IMF transactions using ADJ54. The PDC isn't posted with the transaction or shown with the pending transaction. The pending (PN) MF posting cycle for the IDRS status transaction is extended to account for the PDC(s). Example: A PDC "1" must be used on the adjustment when an address change was input. This allows the adjustment notice to be sent to the new address of record.

# Processing Statute Cases

3.11.6.17.1 (01-01-2026) Processing Statute Cases After completing a statute review per IRM 3.11.6.8.10, Statute Review Screening, use the following instructions to process a statute year case: Note: If a case is stamped "No Statute Issue(s)" , continue processing the case. If a Form 1040 is stamped "Statute Cleared" see IRM 3.11.6.8.10, Statute Review Screening. When verifying the ASED, use today's date. Reminder: Review the case for the 25% omission rule to determine if the ASED is extended (TC 560) or needs to be extended per IRM 3.11.6.7.1, 25% Omission Screening. When verifying the RSED and the received date isn't timely, check the postmark. If the amended return is postmarked on or before the RSED, consider it timely for a refund. See Paragraph 7 below to determine timeliness. Caution: The 25% omission rule does not extend the RSED. Research the IRS Disaster Assistance Program per paragraph 2 below. Without regard to the ASED and RSED, Statute cases not meeting SP criteria must be sent to the appropriate function. If the account is on the retention register, use CC IMFOLB to restore the module before sending correspondence or inputting an adjustment. Once the CC IMFOLB request has been input, suspend the case using "RETREG" as the reason for suspense in CII to allow the TC 370 to post. If the TC 370 hasn't posted when the suspense period expires, send the case to AM. Open case controls with a category code "ST04" or "-X04" on a case meeting SP criteria must be placed in "B" status prior to inputting the adjustment. Upon completion of the adjustment, place the control base back in "A" status. When researching the IRS Disaster Assistance Program, check the current year and one year prior to determine if the taxpayer lived in a declared disaster area. If research shows the taxpayer lives or lived in a disaster area, review the disaster declaration for the following statement, and then follow the table below: Affected taxpayers that need to perform time-sensitive actions described in Treas. Reg. 301.7508A-1(c)(1) and Rev.

# Combat Zone

3.11.6.17.4 (09-04-2024) Combat Zone Submission Processing only processes Combat Zone (CZ) claims that result in a net refund or zero-balance. Caution: Don't confuse CZ cases with the Military Family Relief Act (MFRA) cases. For MFRA cases, see IRM 3.11.6.15.1.1.5, Military Family Relief Act (MFRA) (Line 1). If a -C freeze is displayed on CC TXMOD or CC IMFOL, verify the taxpayer is actively serving in a designated CZ. Treat the return as a CZ case if: There's a -C freeze with a Combat Indicator of 1 on CC IMFOLE. or Taxpayer notates actively serving in a CZ on the return. If a -C freeze with a Combat Indicator of "1" is present, then CC IMFOLE or CC ENMOD shows a TC 500 with a Closing Code (cc). There may be several entry and exit dates present. Use the most recent TC 500 to determine current CZ status. If the closing code is an even number, treat the case as a CZ return. If the closing code is an odd number, don't treat case as a CZ return. Note: If the literal "Combat Zone" is present on IDRS ensure there's a -C freeze before treating the case as a CZ return. The literal without the freeze is only an indication of prior CZ status.

# Math Error Response Cases

3.11.6.17.6 (07-22-2024) Math Error Response Cases When a math error (ME) is present on the taxpayer's account, determine if the amended return is a ME response and addresses the error(s) on the account. The taxpayer is allowed 60-days from the date of the math error notice (the 23C date) to request abatement of the additional tax specified in the notice. If the request is submitted via U.S. mail, use the postmark date to determine if the response was timely. Refer to IRC 6213(b)(2)(A). The taxpayer is allowed a stay of collection during the 60-day time period described above during which collection of the assessment shall not be made, begun or prosecuted. If the taxpayer makes a request for an abatement within 60 days, treat the response as a protest. Refer to IRC 6213(b)(2)(B). An amended return isn't considered an ME response if the date of the ME notice is later than the received date of the amended return. When an ME is set a TC 971 with one of the following CP notices is generated: Notice ... Description ... CP 10 ME on an overpaid module, which causes a reduction of credit elect. CP 11 ME on a module with a balance due of $5 or more. CP 12 ME on a module with an overpayment of $1 or more. CP 13 ME on a module with an even balance, an overpayment of less than $1, or a balance due of less than $5 CP 16 ME on an overpaid module, and part or all of the overpayment is offsetting to satisfy another tax module liability. There are two types of responses to MEs, a substantiated protest and unsubstantiated protest. However, when a taxpayer files an amended return when an ME is present on the account, the return could be a response that: Doesn't address the ME(s) on the account. Agrees with the ME(s) on the account. Is a substantiated protest. A substantiated protest occurs when a taxpayer provides supporting documentation which proves the IRS ME calculation is incorrect. Validate the substantiation by reviewing qualifications needed to allow adjustment. Is an unsubstantiated protest. An unsubstantiated protest occurs when a taxpayer is unable or unwilling to provide the required supporting documentation and still requesting the claim. Is an unsubstantiated response. An unsubstantiated response is an unsubstantiated protest that occurs when the taxpayer addresses the ME(s) but doesn't provide required supporting documentation. If ... Then ... The amended return is an unsubstantiated protest Send the case to AM. Any additional changes on the amended return result in an ME Send the case to AM. The amended return is an unsubstantiated response, and no additional changes are requested Send the case to AM. The amended return is an unsubstantiated response, and additional changes are requested Send the case to AM. The amended return is a partially substantiated response, and partially unsubstantiated response Send the case to AM. The amended return a partially agreed, or substantiated response, and partially unsubstantiated Send the case to AM. The ME is caused by an "ITIN Reject" or "No W-7" See IRM 3.11.6.17.14.1, Returns Received From the ITIN Unit (Form W-7). The ME is caused by ITIN status See IRM 3.11.6.17.14.2, ITIN Status.

# Processing a Timely Substantiated Protest to a Math Error Set on the Original Return

3.11.6.17.6.2 (01-02-2024) Processing a Timely Substantiated Protest to a Math Error Set on the Original Return A timely substantiated protest is a protest that is received within the 60-day time period stated in IRM 3.11.6.17.6 (1), Math Error Response Cases. A correction of a math error (ME) on an original filed return is not an amended return or claim for which the amended claims date is required. When processing a response to a ME set on the original return, don't correspond for forms, schedules, or signatures that were on the original return. Reminder: Taxpayers often use their original figures in column A instead of the IRS corrected figures when correcting a ME. In some instances, a taxpayer may have multiple MEs on the account.

# Estimated Tax Penalty (ETP)

3.11.6.17.8 (09-22-2023) Estimated Tax Penalty (ETP) Estimated tax penalty (ETP) is computed based on the tax shown on the taxpayer's original filed return. However, if the taxpayer files a superseding return, the penalty is computed on the tax shown on that superseding return. The ETP is posted as a TC 170 or TC 176. A TC 170 is a manual assessment of an ETP by the IRS, or a self-assessment via Form 2210, Underpayment of Estimated Tax by Individuals, Estates and Trusts. A TC 176 is a computer-generated assessment of an ETP. Route to AM if the taxpayer is requesting a change to the ETP for the following: A FS change to MFJ (FS 2) A change in withholding A checked box A, B, or E in Part II, Form 2210 Note: If routing a return to EXAM or CAT-A, do not correspond for a Form 2210. When the taxpayer is changing their ETP ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ and a Form 2210 is not attached or none of the boxes in Part II are checked: Do not adjust the penalty Adjust the return for all other allowable issues Send Letter 369C per IRM 3.11.6.11.9, Correspondence for Estimated Tax Penalty (Letter 369C). Math verify the ETP using the AMS worksheets when Form 2210 is attached and at least one of the boxes in Part II is checked. If the difference between the AMS penalty amount and the taxpayer's amount is: ≡ ≡ ≡ ≡ ≡ ≡ ≡ – adjust the account using the recomputed amount.

# CP Notices

3.11.6.17.15 (07-22-2024) CP Notices The CP notices listed below are generated based on criteria from the original return and are processed by SP 1040-X tax examiners. Generally, a CP notice response is considered an informal claim and are processed following normal procedures. Starting January 27, 2023, taxpayers that receive a CP 08 or CP 09 may respond to these notices using the DUT. SP 1040-X tax examiners process CP notice responses received through the DUT using CII. The DUT isn't available for CP 27 responses. Note: There are differences when processing CP notice response depending on the format in which it is received. The differences are in how a case is sent to another area and how the case adjustment is input into the IDRS. Don't send CP 08, CP 09, or CP 27 responses to CAT-A. Don't suspend CP 08, CP 09, or CP 27 responses to Statute. If the notice response is received after the RSED, the claim must be worked following procedures in IRM 3.11.6.17.1, Processing Statute Cases. If there's an indication on the CP notice response that the taxpayer isn't eligible for the specific credit (no other issues involved) and a reply isn't necessary, treat the case as classified waste. See IRM 3.11.6.17.22, Classified Waste. Note: If some of the children qualify the taxpayer for the credit but others don't, then process the CP notice for the qualifying child(ren). Caution: Occasionally taxpayers get confused with the earned income and excess investment income statement and check the box on CP 09, Form 15111, Earned Income Credit Worksheet (CP 09), CP 27 and Form 15112, Earned Income Credit Worksheet (CP 27). Refer to IRM 3.11.6.17.15.2, CP 09, Earned Income Credit - You May Be Entitled to EIC, and Form 15111, Earned Income Credit Worksheet (CP 09), and Form 15111, or, CP 27, EIC Potential for T/P Without Qualifying Children, and Form 15112, Earned Income Credit Worksheet (CP 27), as appropriate, when the earned income and excess investment income statement box is checked. If a CP notice is received and there isn't a TC 150 on the module for the related tax year, take the following action: If ... Then ... A CP 08 or Form 15110 is received Send Letter 76C with the fill-in: We disallowed your claim for the Additional Child Tax Credit because we haven't received your original return. You may be eligible to claim this credit on your original return. A CP 09 or Form 15111 is received Send Letter 76C with the fill-in: We disallowed your claim for the Earned Income Tax Credit because we haven't received your original return.

A signature isn't required for tax years 2022 and subsequent, and the signature area on Form 15110 and Form 15111 has been removed. Caution: For tax years 2022 and subsequent, Form 15112 is required to be signed. If the signature is missing, follow the table in paragraph 11 below. A signature is required for tax years 2021 and prior in the signature area on either the CP 08 or Form 15110, CP 09 or Form 15111, and CP 27 or Form 15112. If the signature is missing, follow the table in paragraph 11 below. If the taxpayer alters the address on a CP notice and an address change can be made per IRM 3.11.6.13.1.1, Address Changes, then use CC INCHG to update the taxpayer address. Use the AGI and earned income (EI) from the Per Computer Column of CC RTVUE for CP Notice calculations. If there's a previously posted adjustment on IDRS, review the adjustment to determine if the CP notice issue has already been adjusted. If the CP notice has already been adjusted, treat as classified waste. See IRM 3.11.6.17.22, Classified Waste. Don't include an amended claims date on CP notice adjustments.

If a Form 1040-X is received and the taxpayer has been sent a CP 08, CP 09, or CP 27, refer to IRM 21.6.3.4.2.7.8, Earned Income Tax Credit (EITC) - CP 09 / CP 27, or IRM 21.6.3.4.2.8.3, Additional Child Tax Credit (ACTC) - CP 08, as appropriate. If there's a previously posted adjustment on IDRS, review the adjustment to determine if the CP notice issue has already been adjusted.

# Unpostable Conditions

3.11.6.18 (01-02-2024) Unpostable Conditions An unpostable condition is created when a transaction can't post (update) to master file due to an unprocessable condition. The most common causes of an unpostable condition are: Reducing an amount below zero Removing an amount that didn't previously exist Adjusting an account without a posted TC 150 Not using a priority code when required A transaction which can't post to master file creates an open unpostable case on IDRS. The open control base is in "A" status with category NLUN which represents the unpostable condition and then assigned to the tax examiner who input the unpostable condition. See Document 6209, IRS Processing Codes and Information, or IRM 3.12.179, Individual Master File (IMF) Unpostable Resolution, for a more detailed explanation.

# CII Case Unpostable Condition Resolution

3.11.6.18.1 (01-09-2023) CII Case Unpostable Condition Resolution When an unpostable condition occurs, a Charge-Out sheet (Form 4251) is generated and contains an Unpostable Code (UPC) to identify the condition that caused the transaction to unpost. Note: If the Charge-Out sheet shows the ASED indicating an imminent statute date (within 90 days) route the case to the Statute Unit for quick assessment. Retrieve the closed CII case from archive. Determine the reason for the unpostable based on the "UPC" and/or "TC-S" code on the Charge-Out sheet, IDRS, and/or the return itself. Perform master file verification to determine if there are any other reasons the return may not be processable. The IAT CSI tool can be used to help in determining the unpostable reason. Input the unpostable code and unpostable RC in the search field. Example: UPC 158 RC 1 would be entered as 1581. Reminder: If you have an unpostable on an account with a -L freeze verify that it wasn't the result of CC DDBCK Selected case. If it was the result of a CC DDBCK Selected case it must be sent as a CC DDBCK Selected case. See IRM 3.11.6.14.4, CC DDBCK. Review CC ENMOD for unpostable conditions as this may have caused the adjustment on CC TXMOD to unpost. Note: If an unpostable condition exists in CC ENMOD close the open case when correcting the account. If there's a previous TC 160 or 161 (late filing penalty) on the account, send the case to AM. Use the following tables to take the appropriate corrective action. Be sure to adjust the correct amount and tax period. If ... IDRS Transaction ... Then ... The return meets AM criteria ACTON C02,TOAMTOADJ,C Input case note "AM to ADJ." Reassign the case to the appropriate queue. The return meets route out criteria other than AM ACTON C02,TO(destination),C Input case note "Case sent to (destination)." Reassign or reroute as appropriate. The error can be corrected ACTON C02,UNPCORR,C Input the Nullified Unpostable (NU) DLN as a case note. The NU DLN is the DLN of the unpostable TC 29X. The NU DLN should match the DLN on Form 4251. Example: Unpostable correction - NU 12345. Input the correct adjustment. The return was posted to the wrong SSN Pull up TXMOD using the wrong SSN. ACTON C02,WRONGSSN,C Input the Nullified Unpostable (NU) DLN as a case note. The NU DLN is the DLN of the unpostable TC 29X. The NU DLN should match the DLN on Form 4251. Example: Unpostable correction - NU 12345. Input the correct adjustment using the correct SSN. Someone else has changed your control base Input a case: "Action was taken on my open control base by (employee IDRS number)- please take any required corrective action." Close your unpostable case (if not already closed). Send the case and charge-outs to the person who took action on your unpostable case. Exception: If the corrective adjustment has already been completed, close the CII case to MISC. Unable to determine the appropriate corrective action See your lead.

# For Lead Tax Examiners - Reversing an Erroneous Adjustment

3.11.6.19.1 (02-17-2023) For Lead Tax Examiners - Reversing an Erroneous Adjustment In the course of an internal quality review, occasions arise where erroneous adjustments are identified. If the tax adjustment can't be deleted, a reversal of the adjustment must be made by the production lead of the tax examiner that created the erroneous refund or other designated production lead. Don't input a corrective adjustment for changes to reason codes, received date, or amended claims date. If the erroneous adjustment generates an incorrect TC 846, the production lead of the tax examiner that created the erroneous refund or other designated production lead must initiate a Refund Intercept when possible using IDRS CC NOREF to stop the refund. See IRM 3.11.6.19.2, For Lead Tax Examiners - Refund Intercept CC NOREF, for time frames and time constraints. Exception: It isn't necessary to input CC NOREF if a TC 846 isn't generated or the TC 846 is for the correct amount, in these cases only input the corrective adjustment. Note: Correspond using a 324C letter if there's a missing signature, form/schedule/ or other issue. Suspend the return waiting for the reply. Input CC NOREF at the same time as issuing the correspondence, if necessary. Verify the erroneous adjustment didn't create an unpostable condition before reversing an adjustment. If an unpostable condition was created: Monitor the account until the adjustment unposts Hold the return until the Form 4251, Return Charge-Out, is received and match the return with the Form 4251 Take the necessary corrective action on the account When an account requires a reversal adjustment: The following must be reviewed: - Adjusted Gross Income (AGI) - Dependents - Taxable income - Non-refundable credits - Other Taxes and Self-Employment Tax - Total Tax - Withholdings - Earned Income Credit - Refundable Credits - Direct deposit IRN amount Reverse all items adjusted. When inputting the reversal: - Include any necessary priority codes on the corrective adjustment. See IRM 3.11.6.16.9, Priority Codes (PC). - Use HC 4 Note: In certain cases, the HC 4 won't stop the refund and/or the notice, but it must be input on all reversals regardless. xMend has the capability of reversing an erroneous adjustment. The reversal button on the xMend tool isn't available until the tax adjustment is input and posted to the tax account. Once the adjustment posts the reversal button becomes active.

CC TERUP and CC RVIEW must be used if available: CC TERUP can be used to TERUP the adjustment on the day of input, but it must: - Be input by the TE that input the adjustment - Be input before 5:00 PM CST on the day the adjustment was input Note: If the erroneous adjustment was input after 5:00 PM CST, CC TERUP may be used until 5:00 PM CST the next day. CC Review can only be used after the time frame for CC TERUP has expired - CC Review is only available for 2 days after the input of an adjustment CC NOREFP will resequence for 14 days for daily IMF accounts and, depending on the day of input, up to 20 days for weekly IMF accounts. Each day, CC NOREFP looks for a matching refund and, when a match is found, it'll stop the refund. Note: If no match is found within these time frames, the CC NOREFP is dropped from IMF processing. Use the following table to determine if the IAT Stop Refund tool can be used to prevent an erroneous refund from generating. If the erroneous adjustment was input before 5:00 PM CST on: Day of Week: Use IAT Stop Refund tool before 9:00 PM CST on the following ... Transaction Posts to MF on the following ...
