# Program Management and Review

3.12.212.1.4 (01-01-2026) Program Management and Review Program Goals: The ERS program objective is to provide timely and accurate correction of extensions that are in the ERS error inventory after data is input via Integrated Systems Remittance Processing (ISRP) and Modernized e-File (MEF). Program Reports: All ERS records are controlled by a Document Locator Number (DLN), and error records are accessed and assigned for correction by block DLN. The daily ERS Error Inventory Report ERS 13-40 lists each block of returns and the number of returns in ERS inventory by program. The ERS system displays with command code ERVOL the real-time volume in inventory by status and by program. Daily, weekly, and periodic reports are available to management through Control-D WebAccess to manage inventory and capture data for program planning and review. See IRM 3.12.37, IMF General Instructions. Program Effectiveness: Tax examiner completed inventory is selected for quality review during real-time processing. This review is conducted according to the procedures in IRM 3.30.30, Embedded Quality for Submission Processing (EQSP) System. Annual Review: This IRM is updated and published annually after review and concurrence by affected offices according to the clearance process established in IRM 1.11.9, Clearing and Approving the Internal Revenue Manual (IRMs).

# Program Controls

# Taxpayer Advocate Service (TAS)

3.12.212.1.9 (01-01-2025) Taxpayer Advocate Service (TAS) The Taxpayer Advocate Service is an independent organization within the Internal Revenue Service (IRS), led by the National Taxpayer Advocate, that helps taxpayers and protects taxpayer rights. TAS offers free help to taxpayers when a tax problem is causing a financial difficulty, when they've tried and been unable to resolve their issue with the IRS, or when they believe an IRS system, process, or procedure just isn't working as it should. TAS strives to ensure that every taxpayer is treated fairly and knows and understands their rights under the Taxpayer Bill of Rights. TAS has at least one taxpayer advocate office located in every state, the District of Columbia, and Puerto Rico. TAS uses Form 12412, Operations Assistance Request (OAR), to start the OAR process of referring a case to the Taxpayer Services (TS) Division, to affect the resolution of the taxpayer's problem. For more information, refer to IRM 13.1.19, Taxpayer Advocate Service, Taxpayer Advocate Case Procedures, Advocating With Operations Assistance Requests (OARs). Refer taxpayers to TAS when the contact meets TAS criteria or when Form 911 Request for Taxpayer Advocate Service Assistance (and Application for Taxpayer Assistance Order), is attached and steps cannot be taken to resolve the taxpayer's issue the same day. See IRM 21.1.3.18, Taxpayer Advocate Service (TAS) Guidelines. The definition of "same day resolution" is within 24 hours. The following two situations meet the definition of "same day resolution" : The issue can be resolved within 24 hours. The IRS takes steps within 24 hours to resolve the taxpayer's issue. When making a TAS referral, use Form 911, and forward to TAS following your local procedures. For more information, see IRM 13.1.7, Taxpayer Advocate Service (TAS) Case Criteria, and IRM 13.1.7.4, Exceptions to Taxpayer Advocate Service Criteria, for information on cases that TAS will no longer accept.

# TAS Service Level Agreements (SLAs)

3.12.212.1.9.1 (01-01-2024) TAS Service Level Agreements (SLAs) The National Taxpayer Advocate reached agreements with the Commissioners or Chiefs of the Taxpayer Services (TS) Division, Small Business/Self Employed (SB/SE) Division, Tax Exempt Government Entities (TEGE), Criminal Investigation (CI), Independent Office of Appeals and Large Business and International (LB&I), that outline the procedures and responsibilities for processing Taxpayer Advocate Service (TAS) casework when either the statutory or delegated authority to complete case transactions rests outside of TAS.

For non-remittance NMF items, SSPND 620. For remittance NMF items, see IRM 3.12.38, BMF General Instructions. SSPND 343 for research before transferring to NMF or Unidentified, depending on instruction from Accounting.

# Unprocessable Documents

3.12.212.2.4 (11-20-2017) Unprocessable Documents Error Resolution System (ERS): When perfection of a document is not possible because correspondence is needed, perform research or refer the document to another area of the campus and suspend using the appropriate action code.

# Research

3.12.212.2.5 (11-20-2017) Research Command Code (CC) INOLE, definer S (INOLES) and the taxpayer's EIN, SSN, Internal Revenue Service Number (IRSN), or Individual Taxpayer Identification Number (ITIN) is used to find the following information: Taxpayer's name and address. Taxpayer's name control. Filing requirements (for BMF and Employee Plans Master File (EPMF) taxpayers). Fiscal Year Month (FYM): The month the taxpayer's tax year ends. Example: If the FYM is 12, the tax year ends in December. See IRM 2.3.47, Command Codes INOLE, EOGEN and SPARQ.

# Error Resolution System (ERS)

3.12.212.3 (11-20-2017) Error Resolution System (ERS) The following extension forms are processed in ERS: Form 2350. Form 4868. Note: Correction instructions for approved Forms 4868, processed as Program 447XX (Document Code 17 and 19) are in IRM 3.12.10, Revenue Receipts. Form 7004. Form 8892. The following Document Code 77 forms are processed in ERS: Form 5466-B. Form 3177.

# General ERS Processing Information

3.12.212.3.1 (01-01-2026) General ERS Processing Information Form 7004 is processed in ERS: Form 7004 is numbered with Tax Class 1, 2, 3, or 5, Document Code 04, and Transaction Code (TC) 620. When the TC 620 posts, it generates a TC 460 (with the same DLN as the TC 620) with the automatic extended due date (Return Due Date (RDD) plus 51/1, 6, or 7 months). Exception: If the TC 620 has Computer Condition Code (CCC) L, no TC 460 is generated and there is no extended due date. The Master File Tax (MFT) code must be edited and transcribed on each record. The following table shows the tax class to be used with each form and MFT code. Tax Class Form 7004 Extension for 1 Form 1042 (MFT 12) Form 8804 (MFT 08) 2 Form 1041 (trust or estate) (MFT 05) Form 1041-N (MFT 05) Form 1041-QFT (MFT 05) Form 1041 (bankruptcy estate only) (MFT 05) Form 1065 (MFT 06) 3 Form 1120 series (MFT 02) Form 1066 (MFT 07) Form 3520-A (MFT 42) 5 Form 706-GS (D) (MFT 78) Form 706-GS (T) (MFT 77) Form 708 (MFT 51) A non-suspense letter or other notice must be manually issued to the taxpayer when the extension request is denied, as there is no automatic notice generated. All money amount fields are transcribed in dollars and cents. Form 3177: Program number 1550X is used. These are numbered with Document Code 77 and Blocking Series 000-499. The Transaction Code is 460. Extended due date must be edited and transcribed for these documents. These documents can't carry a remittance. Form 5466-B: Program numbers 1550X (BMF) or 4550X (IMF) are used. These are numbered with Document Code 77 and Blocking Series 500-699 (BMF) or 500-549 (IMF). The Transaction Code is 120. Form 8892: Program number 1550X is used. These are numbered with Document Code 77 and Blocking Series 000-499. The Transaction Code is 460. Extended due date must be edited and transcribed for these documents. These documents cannot carry a remittance. IMF extension Form 4868 (denied, Program 4550X) and Form 2350 (both approved and denied, Program 4550X): See IRM 3.12.212.9. Form 4868 and Form 2350 are numbered with Document Code 77. The Transaction Code is 460. Note: Correction instructions for approved Forms 4868, processed as Program 447XX (Document Code 17 and 19), are in IRM 3.12.10, Revenue Receipts. Form 2350 is numbered with Blocking Series 400-499. Only records with this blocking series will allow an extended due date past 12/15/YYYY. Extended due date must be edited and transcribed for these documents. These documents cannot carry a remittance.

# Type of Errors

3.12.212.3.2 (11-20-2017) Type of Errors ERS will identify errors according to type and priority. The record heading will show the type of error. This IRM will provide correction procedures for the displays of the errors. There will be records where programming has not furnished a field needed to correct an error; in this case, use GTSEC. This is to be reported to National Office for correction. Action Code Error (Priority I) Section Error (Priority II) ISRP problem code Validity Error Including Field Errors (Priority III) Math and Consistency Errors (Error Codes) (Priority IV)

# ERS Inventories

3.12.212.3.3 (11-20-2017) ERS Inventories Records will be placed in error inventory or workable suspense inventory for correction. Once the record has been accessed and it displays, it must either be fully corrected, placed in suspense for more information, or rejected from pipeline processing. Corrections include correcting errors in editing or transcription. This IRM is the main source of information in correcting the record and the related extension request. Procedures will also be found in IRM 3.12.37, IMF General Instructions and IRM 3.12.38, BMF General Instructions, which provide general instructions for correcting errors, document control, inventories, and management reports.

# Error Inventory Report

3.12.212.3.4 (11-20-2017) Error Inventory Report Each day the Error Inventory Report, ERS-13-40, will be furnished showing the blocks by the block control number and block DLN in DLN order. Each batch will be on a separate page. Blocks received from Block Out of Balance (BOB) Correction will be listed separately. A copy of the Error Inventory Report can be placed on the carts of documents and used as a charge-out. This will help to determine when a cart is completed. The first line of the Error Inventory Report will show the number of working days the records on that page have been in the error inventory. This will enable work left from a previous day to have priority.

# Status Codes

3.12.212.3.5 (11-20-2017) Status Codes Records for the documents in ERS are controlled by status codes. The status is updated when the records are placed in specific inventory. Below is a list of the status codes and brief explanation: Status 100 is an error awaiting correction. Records are in the error inventory. Status 2XX is a record awaiting information. Records are in the suspense error inventory. Status 3XX is a record the suspense period expired, and the record was not activated, or there was no response. Records are in the workable suspense inventory. Status 4XX is a record with information awaiting correction. Records are in the workable suspense inventory. Status Code 900 is a record is in the unpostable inventory. The final two positions of the Status Code are the first two positions of the action code. This groups similar work together on the workable suspense inventory. Example: Status 321: Suspense period expired, no response to taxpayer correspondence. If a record has been selected to be held for Quality Review, the positions 2 and 3 will be QA.

# Workable Suspense Inventory Report

3.12.212.3.6 (11-20-2017) Workable Suspense Inventory Report Each day the Workable Suspense Inventory Report shows the records by program, in DLN order, for various statuses, and totals. The first line of the report shows the number of working days the records have been in the workable suspense inventory. The oldest work must be prioritized.

# Action Codes

3.12.212.3.7 (11-20-2017) Action Codes An ERS action code indicates the document is missing specific information, must be suspended, and/or must be removed (rejected) from processing. The code has sufficient detail to indicate if correspondence is to be sent to the taxpayer, or the specific in-house research or action required. Code and Edit assigns action codes when numbered extension requests are unprocessable, more information is needed, or a manual intervention is required. The code is entered on the bottom of the extension. Correspondence Action Sheets (Form 3696 and Form 13482) are attached by Document Perfection. When routing within the campus for in-house research, an explanation concerning the missing information needs to be attached to the extension request. The action code assigned by Code and Edit is transcribed in the record of the document. A valid action code other than 001 will place the record in the suspense inventory, either workable or unworkable. A charge-out (Form 8161) is computer-generated for all new suspense items. The charge-out is used for pulling documents, and routing and controlling documents while the record is held in suspense, and associating the document with the workable suspense inventory when the record becomes workable. When a record displays on the workable suspense inventory with the action code as first priority: Add the information received to the record or follow the IRM instructions for the no reply, and clear the action code by entering C in the Clear Code Field and transmitting. Once the action code is cleared, any validity, section, or math/consistency errors will display for correction. Records that were unprocessable can require re-suspension for more information. A charge-out will not be generated for resuspended items. Make a notation in the appropriate block of the charge-out by entering the action code and date. Some action codes can't be resuspended. If this occurs, make a notation in the appropriate block of the charge-out by entering the correct action code and date. When perfection is not possible, reject the record and initiate action to void the DLN. If remittance is involved, transfer it to the Unidentified Remittance File (URF). If Perfection is not possible and the record requires renumbering or uncorrectable fields need correction, reject the record for reinput using RJECT with Action Code 630 (reinput) or 640 (void). If a new DLN is needed, use NWDLN with the appropriate action code and new DLN Master File Identification code, if required. A charge-out will generate for all rejected records. The charge-out remains in the campus files for future reference. Note: If the DLN was transcribed incorrectly, the DLN on the charge-out is erroneous. Notate the correct DLN on the charge-out for pulling the document. Inform your supervisor of the block involved and the location of the document. ERS automatically controls most of the adjustments to Service Center Control File (SCCF). When manual adjustment is required, use Form 4028, Service Center Control File Adjustment Record (SCCF Format Code 216). Only one action code can be assigned at a time to a record. The action code priority is 310, 4XX, 6XX, 3XX, 2XX. An action code can be entered on a record, delete or correct an invalid code, or enter another action code to resuspend or reject from ERS. Use RJECT, SSPND, or NWDLN with a valid action code. SSPND with an action code clears the record and places the record in workable suspense or unworkable suspense. RJECT with an action code deletes the record from ERS. SCCF automatically updates for the rejected records.

# Clear Code C and 000.

3.12.212.3.9 (04-11-2019) Clear Code C and 000. A field labeled CL will display for the entry of a clear code when there is a possibility that a change or correction will not be needed. The Clear Code Field is located to the right of CRECT on the screen display. Error codes are cleared by either correcting the condition or entering a C in the Clear Code Field to indicate no correction is needed. If corrections are made, transmit before entering Clear Code C. Code C is used for clearing the action code after corrections have been completed, or as with Action Codes 410 and 700, the action code must be cleared initially so other errors in the record can be resolved. The numeric 000 is used as a clear code when deleting action codes. It will be used for erroneous action codes when there's no reason to suspend the record. The numeric 000 can't be used in suspense correction. Programming erases all clear codes for error codes when a record is suspended using SSPND. Programming erases all clear codes for error codes and action codes for the new day's error inventory and workable suspense inventory. Unfinished records from the previous day won't contain any of the clear codes that were assigned to a record that wasn't completely worked. Error codes (including the ones which require a clear code) are numbered consecutively for correcting. There can be instances when an error code with a higher priority will display. Beginning with the higher priority error code created, programming will continue displaying error codes for the record. The corrected data can be different from those previously displayed. There can be instances when an error code which was previously cleared no longer displays. If there are errors remaining on the record, they will display for resolution. The clear code prevents any other corrections to the record. If a correction must be entered and the error is no longer displayed, use GTRECW to make corrections.

# Correspondence

3.12.212.3.10 (01-01-2025) Correspondence You might have to correspond if Code and Edit didn't correspond for missing or contradictory information, or to notify the taxpayer the extension hasn't been approved for Form 4868, Form 2350, Form 7004 and/or Form 8892. Note: If Code and Edit did correspond, the specific letter used is notated on the extension form. The following table shows the available Correspondex Letters to use when corresponding with the taxpayer. For other correspondence questions, you can reference IRM 25.13.1, Taxpayer Correspondence Services. Letter Title 0296C Extension of Time to File (IMF/BMF) Incomplete for Processing 0297C Extension of Time to File and/or Pay (IMF/BMF); Denial Explained 0333C Extension of Time to File (IMF/BMF) Approved 3699C Extension of Time to File (BMF) Note: Other letters, forms, or Form 5260, Quick Note, can be used for correspondence if appropriate to the situation. See Exhibit 3.12.212-16, Form 5260, Quick Note. When the taxpayer replies to correspondence, enter the correct information provided by the taxpayer. When there is no reply from the taxpayer for correspondence requesting information needed to process the extension, follow the no reply instructions for the error code, and ensure an audit trail is notated on the extension form. If the document carries a remittance, reinput the form as a non-remittance document and prepare Form 3244 with TC 670 to post the payment to the appropriate account. If unable to determine the appropriate account, send payment to Unidentified Remittance Unit. When correspondence is returned as undeliverable, research attachments and IDRS for another address. If found, send the correspondence to the new address. If no new address is found: And the correspondence was requesting information, follow no reply procedures. And the correspondence was notification to the taxpayer the extension request was not approved, destroy the correspondence.

# Field Errors

3.12.212.3.11 (11-20-2017) Field Errors Any field not meeting the requirements for that field will display as a field error. Reasons for this are: Non-alpha character in an alpha field. Blank space in a numeric field. Blank in the first position of an alpha field. All fields with a field error will be displayed in the order encountered in the record. The action code will not display as a field error.

# Section Errors

3.12.212.3.12 (11-20-2017) Section Errors There are two types of errors which are identified as section errors - ISRP and Terminus errors. ISRP errors are detected by the ISRP System. The table below identifies the ISRP error displayed. Code Meaning 1 Split screen transmission: Key verifier attempted to change check digit, key verifier changed 4 or more digits of TIN, or the original entry operator entered required section as missing. 3 Invalid section ending point. 4 Invalid field length. 5 Questionable Section: The ISRP operator input the same section more than once. The computer program will drop all duplicate sections and display the first one encountered. An ISRP error will display for all fields except Remittance in Section 01. Transcribed data will be present; computer generated data will not be present. Correct coding and transcription. Once the section is correct, drop the cursor to the bottom of the screen and transmit. When all fields have been corrected, enter C in the Clear Code Field and transmit. Terminus Errors are caused by a section with variable length fields containing an erroneous size field. This error will display for all fields of the terminus section except for computer generated fields or Remittance in Section 01. Correct coding and transcription. When all fields have been corrected, drop the cursor to the bottom of the screen and transmit.

# ERS Error Codes General

3.12.212.3.13 (11-20-2017) ERS Error Codes General An error code is computer generated to a record and assigned in numerical order. Each field that displays in each error code is defined by an Alpha/Numeric Field Designator (AFD). Error codes will be displayed in ascending numerical order. Error codes require at least one of the following three actions using IRM instructions: Correct the invalid conditions. Enter C in the Clear Code Field. Suspend the document with the appropriate action code.

# Scanned Paper Returns

3.12.212.3.14 (01-01-2026) Scanned Paper Returns Starting in 2025, the timely filed paper Form 7004, Form 4868, and Form 8868, will be scanned as part of the Scanned Paper Returns (SPR) project. Scanned Paper Returns can be identified in the Employee User Portal (EUP) by the following: The notation "Converted from Paper" , will be present. The attached PDF scan of the original return, "IRS Form 4868 Document" , "IRS Form 7004 Document" , "IRS Form 8868 Document" will be present. Note: Transcription errors will be present on Scanned Paper Returns. Some fields can contain invalid or incorrect data if the field is blank or illegible during the scanning process. Verify and perfect the fields in IDRS using the attached scanned document. Extensions that go through scanning will need to have an additional National Account Profile (NAP) verification. For scanned returns that fall out on entity field errors or error codes, drop the cursor to the bottom of the screen and transmit first.

# Determination of Timely Filing/Received Date - General

3.12.212.4 (01-01-2026) Determination of Timely Filing/Received Date - General Caution needs to be taken to determine when an extension was filed. The received date is the date the extension was received by the IRS. Receipt and Control will stamp a received date on all extensions and attach the envelope. If more than one extension request was included in an envelope, the postmark date will be stamped on each additional extension. An extension is timely filed if the received date is ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ or if it has a postmark date on or before the due date. ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ If the due date falls on a Saturday, Sunday, or legal holiday, the extension is timely if it is postmarked by the following day that is not a Saturday, Sunday, or legal holiday. For example, if April 15 fell on a Sunday, the extension would be considered timely if postmarked by April 16. Note: ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ Under the timely mailing treated as timely filing rules of IRC 7502, the filing date is the postmark date if the postmark date is on or before the due date of the extension and the extension is received after the due date. Note: An extension with a timely foreign postmark would be timely filed based on Rev. Rule 2002-23. Rejected electronically filed IMF extension request: If the taxpayer attempted to timely file Form 4868 or Form 2350 electronically and it was rejected, the paper request must be filed by the later of the regular due date or 10 calendar days after the date of the notification the electronic submission was rejected. Rejected electronically filed BMF extension request: If the taxpayer attempted to timely file Form 7004 electronically and it was rejected, the paper request must be filed by the later of the due date or 5 calendar days after the date of the notification of the rejection. Officially declared disasters: If the address on the extension is in a state covered by an officially declared disaster, or a FEMA number or disaster designation is notated, and the extension is postmarked on or before the disaster end date granted by the Commissioner in the Federal Emergency Management Agency disaster memo, the extension is timely filed. See Exhibit 3.12.212-17. If more than one extension request is included in a single envelope, Receipt and Control will stamp the postmark date on the face of each additional extension document. Exceptions to normal due date: Some taxpayers are allowed more time to file their extension request. If any of the following criteria are found, the extension is timely filed if received or postmarked by the 15th day of the 6th month after the end of the tax period, adjusted for weekends and holidays (e.g., if postmarked by 06/16/2026 for tax period 202512.) ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡. Form 7004: The taxpayer indicates 26 Code of Federal Regulations (CFR) section 1.6081-5 or checks the box on line 4. Note: If the box on line 4 of Form 7004 is checked, partnerships and Form 1120-S filers receive an additional 3-month extension, and C corporation filers receive an additional 4-month extension. See Exhibit 3.12.212-13. Form 7004: The taxpayer checks the box on line 2; it's not necessary for the extension to show a foreign address. Form 4868: The box on line 8 is checked, or the taxpayer indicates on the extension form or attachments that the taxpayer is "out of the country" or "taxpayer abroad," or the taxpayer is in military service stationed abroad. Form 4868: The box on line 9 is checked, the taxpayer indicates "1040-NR no withholding," or "no withholding." Form 2350: Taxpayers are generally considered to be "out of the country" ; so they would qualify for the 06/15/YYYY due date. There is no reasonable cause for late filed extensions, unless the Commissioner has extended the due date for filing due to a situation contained in Policy Statement 3-12. Policy Statement 3-12 states, "The Commissioner may extend the due date of filing returns for broad classes or groups of taxpayers, but only in cases of natural disaster, catastrophe or other extraordinary situations." If the received date is invalid, such as an incorrect year was used when the date was stamped, and other information (Julian date, postmark date, and/or signature date) indicates the received date should be the current year, change the received date year to the current year. Example: Form 7004 has a stamped received date of 06/15/2025, the tax period is 202603, and the postmark date is 06/15/2026. The postmark date indicates 2026 is the correct year of the received date. Change Field 01RCD to 20260615. Determine received dates using the following priority: IRS date stamp. Note: Earliest date stamp by Campus, Area Office, US Consulate, or Revenue Officer. The earliest legible postmark date (U. S. Postal Service, Foreign Postmark, or Private Delivery Service) on the envelope or stamped on the face of the document. Service Center Automated Mail Processing System (SCAMPS) date. Revenue Officer's signature date. Signature date (Form 2350 only). Julian date minus 10 days. Use the due date charts for the specific forms in the following exhibits: Exhibit 3.12.212-7, Form 7004 Due Dates - Form 706-GS(D), Form 706-GS(T), Form 1042, and Non-Master File returns Exhibit 3.12.212-8, Form 7004 Due Dates - Form 1041, Form 1041-N, and Form 1041-QFT Exhibit 3.12.212-9, Form 7004 Due Dates - Form 1065, Form 1066, Form 1120-S, Form 3520-A, and Form 8804 Exhibit 3.12.212-10, Form 7004 Due Dates - Form 1120 series (except Form 1120-C, Form 1120-POL, Form 1120-S, and Form 1120-F with box 2 or 4 checked) Exhibit 3.12.212-11, Form 7004 Due Dates - Form 1120-C Exhibit 3.12.212-12, Form 7004 Due Dates - Form 1120-POL Exhibit 3.12.212-13, Form 7004 Due Dates - Line 4 box is checked Exhibit 3.12.212-14, Form 4868 Due Dates For further information, see IRM 3.10.72, Receiving, Extracting, and Sorting, and IRM 3.11.212, Applications for Extension of Time to File.

# BMF - Correction of Errors for Form 7004

3.12.212.5 (01-01-2026) BMF - Correction of Errors for Form 7004 Use the following instructions to correct errors for Form 7004 extension requests. Partnership returns, S corporation returns, and their extension requests are due 21/1 months after the tax period ends (March 15 for calendar year Form 1065 and Form 1120-S). Form 1120 series returns and extension requests for C corporations (other than Form 1120-C, Form 1120-POL, and corporations that end the tax year on June 30) are due 31/1 months after the tax period ends (April 15 for calendar year Form 1120). C corporations with a tax year ending on December 31 receive 6-month extensions. C corporations with a tax year ending on June 30 are due 21/1 months after the tax period ends (September 15), and receive 7-month extensions. Exception: All Form 1120-POL returns and extension requests are due 31/1 months after the tax period ends and receive 6-month extensions, regardless of tax period ending date. Form 1120-C returns and extension requests are due 81/1 months after the tax period ends and receive 6-month extensions. Form 1041 (trust) and Form 1041 (estate other than a bankruptcy estate) extension requests receive 51/1 month extensions. Form 7004 can be filed electronically. Forms filed electronically are corrected using the same procedures as manually transcribed documents. Electronically filed Forms 7004 can be identified by File Location Code (first two digits of the DLN) 88, 93, or 92 for domestic filers, or 66 or 98 for foreign filers for Program 11710. See IRM 3.42.4, IRS e-file for Business Tax Returns. Note: Form 8612, Form 8613, Form 8725, Form 8831, Form 8876, and Form 709-GS (D) can't be e-filed.

If Field 01TXP is incorrect, review the received date and postmark date to determine timeliness of the extension based on the corrected tax period before making corrections to Field 01TXP. See IRM 3.12.212.4. If the extension is timely filed based on the corrected tax period, delete L from Field 01CCC if present. If the extension is late filed based on the corrected tax period, enter L in Field 01CCC, and initiate correspondence using non-suspense letter 3699-C to notify the taxpayer the extension is denied due to late filing. See IRM 3.12.212.3.10. Some entities file 52–53 week returns. Their tax year ends on the same day of the week each year (e.g., the last Friday in December). Tax periods reported under the 52-53 week rule can end no more than 6 days before, and no more than 3 days after, the end of a month. When determining the tax period for these accounts, use the month that the last day of which is closest to the actual ending date. If the tax year ends in the first 3 days of a month, use the previous month in the tax period. Example: If the end of the tax year is April 3, 2026, use tax period 2603. If the tax year ends up to 6 days before the end of the month, use that month in the tax period. Example: If the end of the tax year is March 27, 2026, use tax period 2603. Form 7004, MFT 78, 77, or 12 (Form 706-GS (D), Form 706-GS (T), or Form 1042): Change the tax period month to 12 in Field 01TXP.

# Short Period, Form 7004

3.12.212.6.7.2.2 (01-01-2023) Short Period, Form 7004 Check line 5b for an indication the extension is being filed for a short period because an Initial, Final, or Change in accounting period return will be filed. If any of these boxes are checked, enter W in Field 01CCC. Only one CCC can be entered for each document. If CCC L is present, do not enter W in Field 01CCC. Instead, change Field 01TXP to match the underprint month in the current year (e.g., If Field 01TXP is 202512 and underprint is 06, change Field 01TXP to 202606). If this makes the extension timely filed for the new tax period, delete L from Field 01CCC. Check line 3 and line 5b for an indication a consolidated return will be filed. If either box is checked, or a notation on the extension form or an attachment a consolidated return will be filed, enter W in Field 01CCC. If none of the above boxes are checked, look for any of the following taxpayer notations/indications. If found, enter W in Field 01CCC. Treasury Regulation 1.1502–76, or IRC 444, IRC 7519, or IRC 280H. Revenue Procedures 76–10, 85–58, 2000–11, 2002-37, or 2002-38.

Form 1065 (Common Trust Fund). Sub-chapter S election or termination. Note: If CCC L is present, do not enter W in Field 01CCC. Instead, change Field 01TXP to match the underprint month in the current year (e.g., if Field 01TXP is 202512 and the underprint is 04, change Field 01TXP to 202604.) If this makes the extension timely filed for the new tax period, delete L from Field 01CCC. If unable to resolve, see IRM 3.12.212.6.7.2.3.

# Research CC INOLES

3.12.212.6.7.2.3 (11-20-2017) Research CC INOLES Research using CC INOLES for the FYM of the MFT matching the return being extended.

If no transaction is present, see IRM 3.12.212.6.7.2.4.

# Research CC BMFOLI

3.12.212.6.7.2.4 (11-20-2017) Research CC BMFOLI Research using CC BMFOLI for prior filing pattern for the tax return (TC 150). If research shows no returns posted to prior tax modules for the MFT of the extension, assume this is an initial filing. Enter W in Field 01CCC. Review the FYM of returns that have posted to tax periods prior to the tax period on the extension: If And Then The returns posted are for the same FYM on the extension, Enter W in Field 01CCC. Exception: If CCC L is present, bring up the underprint month. The returns posted are for various FYMs, Initiate correspondence to the taxpayer requesting clarification of the accounting period. Note: Don't correspond on disapproved extensions. Follow No Reply instructions.

Rejects will research for a posted extension (TC 460) for the current year. If TC 460 posted to the current year, SSPND 480 as an early filed extension. If no TC 460 is posted, change FYM to the current year and bring up the underprint month. If this makes the extension late filed, enter L in Field 01CCC and notify the taxpayer using non-suspense letter 3699-C. The returns posted are for the same FYM and are different from the FYM on the extension, There is no TC 150 posted for the current year, Change Field 01TXP to the current year and bring up the underprint month. If this makes the extension late filed, enter L in Field 01CCC and notify the taxpayer using non-suspense letter 3699-C. If the extension was originally disapproved for late filing, and after following the correction procedures the extension is now found to be timely filed, delete L from Field 01CCC.

# Reply or No Reply Error Code 026, Form 7004

3.12.212.6.7.2.4.1 (01-01-2023) Reply or No Reply Error Code 026, Form 7004 If the taxpayer's reply provides a tax period and the month matches the tax period underprint, enter the correct tax period in Field 01TXP. If the taxpayer replies with an approved copy of Form 1128, Form 8716, or a date the accounting period change was approved, SSPND 320. If the taxpayer quotes an IRC Section or Rev. Proc. to explain the change, enter W in Field 01CCC. If the taxpayer replies the corporation is changing to a sub-chapter S corporation, enter W in Field 01CCC. Note: The permitted sub-chapter S corporation year is a calendar year, a tax year permitted under Section 444 (9/30, 10/31, or 11/30), or an ownership taxable year or natural business tax year (see Rev. Proc. 2002-38, 2002-1, C.B. 1037). Corporations cannot change their tax year just prior to changing their status to a sub-chapter S corporation unless Form 1128 is filed. If the taxpayer's reply indicates this is the case and there is no indication Form 1128 has been filed, process as no reply. If the taxpayer indicates the corporation will file a consolidated return with another corporation with a different tax year, enter W in Field 01CCC. The taxpayer will notate Reg. 1.1502-76. The due date of the extension is the due date of the parent return, based on the short tax period on the extension. Note: A corporation can not change its accounting period because it is coming out of consolidation with another corporation without prior approval. If there is no indication Form 1128 or Form 8716 has been filed, treat as no reply. If the taxpayer indicates the extension is filed for a final return, enter W in Field 01CCC. If no reply or reply is incomplete: If Then BMFOLT shows a TC 460 posted for the current year, SSPND 480 and hold as an early filed extension. Example: BMFOLT shows a TC 460 posted to tax period 202509 and the extension shows tax period 202512. FYM underprint is 09. SSPND 480 and hold as an early filed extension for tax period 202609. BMFOLT does not show a TC 460 posted for the current year, Change Field 01TXP to agree with the tax period underprint month in the current year. Example: Tax period underprint is 12, the extension shows tax period 202506. BMFOLT shows no TC 460 posted for 202512. Received date is 03/12/2026. Change Field 01TXP to 202512. The change in the tax period will make the extension late filed, Enter L in Field 01CCC before making the correction to Field 01TXP. Reminder: Send non-suspense letter 3699-C to notify the taxpayer of the denial and the reason.
