# Taxpayer Advocate Service (TAS)

3.12.166.2.1 (10-24-2022) Taxpayer Advocate Service (TAS) The Taxpayer Advocate Service (TAS) is an independent organization within the Internal Revenue Service (IRS), led by the National Taxpayer Advocate. Its job is to protect taxpayers' rights by striving to ensure that every taxpayer is treated fairly and knows and understands their rights under the Taxpayer Bill of Rights (TBOR). TAS offers free help to taxpayers, including when taxpayers face financial difficulties due to an IRS problem, when they are unable to resolve tax problems they haven't been able to resolve on their own, or when they need assistance to address an IRS system, process, or procedure that isn't functioning as it should. 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. Form more information, refer to IRM 13.1.19, 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. 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. 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 local procedures. See IRM 13.1.7, Taxpayer Advocate Service (TAS) Case Criteria, for more information.

# Taxpayer Advocate Service Level Agreement

3.12.166.2.2 (10-24-2022) Taxpayer Advocate Service Level Agreement 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 (TE/GE) Division, 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. These agreements are known as Service Level Agreements (SLAs). The SLAs are found at TAS Service Level Agreements.

# Operations Assistance Requests (OARS)

3.12.166.2.3 (10-24-2022) Operations Assistance Requests (OARS) The Taxpayer Advocate Service uses the Operation Assistance Request (OAR) process to refer cases when TAS lacks either the statutory or delegated authority to resolve a taxpayer's problem. The TAS uses Form 12412, Operations Assistance Request (OAR), to initiate the OAR process. In cases requiring an OAR, TAS completes Form 12412 and forwards the case to the Operating Division Liaison via Form 3210, Document Transmittal. The Operating Division Liaison reviews the case, assigns it to the appropriate area, and monitors the case through its conclusion. When TAS requests expedite processing, Operating Division or Functions Liaisons acknowledge receipt via Form 3210, secure messaging e-mail, fax, or by phone within one workday of receipt of the OAR. For OARS that don't require expedite processing, the Operating Division or Functions Liaisons acknowledge receipt via Form 3210, secure messaging e-mail, fax, or by phone within three workdays of receipt of the OAR. Make every effort to expedite completion of OAR cases. Form 12412 indicates timeframes for the assigned area to complete the case. Manager/employee: Work with the Taxpayer Advocate contact listed on Form 12412 to arrive at agreed upon timeframes for follow-up based on the facts and circumstances of the particular case. Employee: If you can't resolve a taxpayer's case by the requested timeframe or by a negotiated extension date, immediately notify your manager. Manager/employee: Discuss the findings and recommendations on the final disposition of the case with the appropriate TAS contact. The TAS contact is responsible for communicating the final decision on the case to the taxpayer. However, you and your manager can also communicate the decision to the taxpayer. Upon case resolution, the TE/GE employee assigned the OAR completes section VI of Form 12412 and returns it to the TAS Case Advocate assigned the case. Return the Form 12412 within three (3) workdays of completing all actions and posting all transactions. Manager/employee: If you and the TAS contact can't agree upon the resolution to the taxpayer's problem, the TAS employee elevates the disagreement to their manager who discusses it with the appropriate Operating Division manager. You and your manager are to also elevate any disagreement to their manager. For more detailed information, refer to: IRM 13.1.19, Advocating With Operations Assistance Requests (OARs), or the TAS SLA website at Service Level Agreements.

# General Information and Introduction

3.12.166.3 (01-01-2025) General Information and Introduction The Ogden Campus processes all EPMF Unpostables, even if generated at another location. Use Command Code (CC) CMODE to access and close EP unpostables at other service centers. The Employee Retirement Income Security Act (ERISA) Filing Acceptance System (EFAST) 2 project moved processing to a vendor contracted by the Department of Labor (DOL). EFAST2 is a computerized processing system designed to simplify and expedite the receipt and processing of the Form 5500, Form 5500-SF and as of January 1, 2021, the Form 5500-EZ by electronic filing. Beginning January 1, 2025, Form 5558 can be filed electronically through EFAST2 or with the IRS on paper. More than one million pension, welfare and fringe benefit plans file Forms 5500/5500–EZ/5500-SF each year to satisfy reporting requirements under ERISA and the Internal Revenue Code. Unless otherwise specified in the specific unpostable instructions, use the procedures in this IRM when resolving all EFAST2 and campus unpostables. Report problems encountered the same business day as they're discovered to the local Submission Processing P&A analyst who will forward to the TE/GE Headquarters Submission Processing Program & Oversight (SPP&O) analyst. The Form 5500-EZ can also be paper filed at the Ogden Submission Processing Campus. Unless otherwise specified in the specific unpostable instructions, use the procedures in this IRM when resolving all Form 5500–EZ unpostables. Report problems encountered the same business day as they're discovered to the local Submission Processing P&A analyst who will forward to the TE/GE Headquarters Submission Processing Program & Oversight (SPP&O) analyst. The Taxpayer Bill of Rights (TBOR) lists rights that already existed in the tax code, putting them in simple language and grouping them into 10 fundamental rights. Employees are responsible for being familiar with and acting in accordance with taxpayer rights. See IRC 7803(a)(3), Execution of Duties in Accord with Taxpayer Rights. For additional information about the TBOR, see Taxpayer Bill of Rights.

# Unpostable Guidelines

3.12.166.3.1 (07-25-2024) Unpostable Guidelines General Procedures for Unpostables are as follows: Operations Branch loads and takes Unpostables into the Unpostable, Criminal Investigation, Exam, Statute and Entity inventories within 3 days after Campus receipt from MCC. Support Branch transmits the closed Unpostable to MCC by each Thursday or they will miss the MCC weekly update. Missing the update causes adverse effects. Example: Incorrect cycling. Keep inventories to a manageable level. The Headquarters and Campus measuring device are the weekly Control D reports. (Unpostable Inventories, Unpostable Receipts, etc.) Work total aged Unpostable cases as quickly as possible. Don't exceed 10 PERCENT(per Master File) of the ending inventory. Unworkable and workable inventory levels (excluding Bankruptcies) and cycle closures shouldn't exceed a 14 workday processing cycle. Unpostables start aging from the date the document failed to post at Master File. Entity Unpostables (GUF category B4) will age in 10 cycles from the original unpostable cycle. Repeat Unpostables won't exceed 10 percent of the current week's receipts per Master File (i.e., BMF, IMF, EPMF, etc.). Repeat unpostables retain the original date the document failed to post at Master File. Issue correspondence for unpostable cases within 10 days of determining contact is needed. If the campus ending inventory exceeds their receipts by 15 percent for three consecutive weeks, or their aged inventory exceeds 10 percent per week (per Master File) the inventory is unmanageable. Management takes stringent measures to bring percentages back to manageable levels. The following are for all functions working unpostables to help in maintaining these levels: Expedite the reinput of pending nullified unpostables. Don't shelve reinput returns. Review and completely resolve all unpostable conditions that can result in a repeat unpostable for the specific unpostable. Review the aged inventory. Work the high dollar amounts and the oldest cases first to keep their numbers to a minimum. Give refund and payments processing, including Federal Tax Deposits (FTD), a higher priority than other unpostables. Local management decides highest priority. After the return due date, refund returns receive the highest priority to meet the 45-day interest-free period. Note: Ensure manual refunds are issued on all applicable refunds (i.e., refunds of 1 million dollars or more). Refer to IRM 21.4.4, Manual Refunds, for refund transactions. Conduct a 100 percent review on all repeat unpostables for each Master File. Maintain adequate staffing and terminals at each Campus.

# General Unpostable Instructions

3.12.166.3.2 (07-25-2024) General Unpostable Instructions IRM 3.12.32, General Unpostables, provides: Instructions for input of terminal requests to display, suspend, research and resolve unpostable cases. General guidelines regarding processing of Unpostable cases. Case reassignment guidelines and procedures. MASS closure guidelines, batch and Integrated Submission and Remittance Processing (ISRP) guidelines, and certain FILES closure guidelines. However, if a case designated for "MASS" closure is reassigned (from the SC or "unit" number) to an INDIVIDUAL, the case will be closed per instructions in this manual. Unpostable category information, details for Form 4251, Return Charge-Out, specific details and explanations of Unpostable Listings and Reports, Command Code descriptions, Terminal Screen formats, and general Unpostable Resolution Code (URC) corrective action descriptions. IRM 3.12.166 provides the definition of the unpostable code and procedures for correcting EPMF and BMF case closures for INDIVIDUAL and FILE type unpostable conditions. GUF CCs UPDIS (display), UPRES (case closure) and INOLE (National Account Profile (NAP) Database) are used in this section for EPMF unpostable resolution. This section provides a general background of known procedures for resolving unpostables. Where possible, this section gives detailed procedures. When unable to follow the detailed procedures, use the general procedures as the primary guide.

# General Concepts and Correspondence Guidelines

3.12.166.4 (07-01-2021) General Concepts and Correspondence Guidelines In resolving unpostable records, follow the intent of the preparer as far as possible within the provisions of the Internal Revenue Code and the appropriate Master File computer program constraints. If there's a conflict between the general and specific instructions, follow the specific instructions for that Master File and/or unpostable code.

# Taxpayer Correspondence

3.12.166.4.1 (07-01-2021) Taxpayer Correspondence The Restructuring and Reform Act of 1998, section 3705(a), provides identification requirements for all IRS employees working tax-related matters. This section requires that any manually generated correspondence received by a taxpayer from the Internal Revenue Service (IRS) will include in a prominent manner the name, telephone number and unique identifying number of an IRS employee the taxpayer may contact with respect to the correspondence. We generally define "manually generated correspondence" as IDRS "C" letters used for requesting missing information, forms or schedules from returns received for processing. The term "manually generated correspondence" concerns correspondence to taxpayers that contain the following elements. The IRS employee issuing the correspondence is: Exercising judgment in working or resolving a specific case, responding to specific taxpayer correspondence, or asking the filer to provide additional case related information. In the best position to answer any questions the taxpayer may have about the correspondence. The Service must use sound business judgment to determine the provision's applicability. Don't apply the provision to general correspondence involving rejects and suspense functions where the question could be resolved by any IRS employee (e.g., missing schedule, signature, etc.). Use the selective paragraph with Letter 1072C, Employee Plan EIN Missing/Requested/Assigned Information, if applicable. However, in most instances, a Tax Examiner (TE) name and phone number won't need to be included with Letter 1072C since the case isn't being suspended for a reply. Letter 1072C notifies the filer of action taken to close the case. Always enter the letter sent on an account in the remarks field (line 8 of UPRES). Before initiating any correspondence (or telephone contact), check the Centralized Authorization File (CAF) to either: Ensure any authorized representative(s) will receive copies of the correspondence. Verify you have the right to speak to the proper representative. Correspondence Handbook is the central authority for handling taxpayer correspondence. Refer to IRM 21.3.3, Incoming and Outgoing Correspondence/Letters. This IRM takes precedence over all other handbooks addressing the Service's handling of taxpayer correspondence. Refer to IRM 3.30.123, Processing Timeliness: Cycles, Criteria and Critical Dates, for suspense days and maximum days to process correspondence replies. If a Letter 1072C sent from EP Entity Unpostables returns as Undeliverable, follow the instructions for Undeliverable Correspondence found in IRM 3.13.36.25, Correspondence.

# Undeliverable Mail Indicator

3.12.166.4.2 (06-27-2024) Undeliverable Mail Indicator An undeliverable mail (UD) indicator is input on taxpayers' accounts when returned mail is received back from the United States Postal Service (USPS) as undeliverable. The UD indicator is generated with the input of TC 971, action code (AC) 661, on IDRS, which suppresses the generation of non-statutory notices and letters. The warning and suppression are intended to be temporary until the taxpayer's address has been updated. Currently, when employees create a correspondex (CRX) letter using the IAT Letter Tool, they use the taxpayer's existing address on IDRS. Effective August 7, 2023, if a letter is being sent to a taxpayer with a UD indicator on their account, the initiator will receive an alert to do the following: Verify the entity information and determine if a new address is available. Update the taxpayer's address if a new address is found. Remove the UD indicator from the account. Issue the applicable letter following normal procedures. When issuing a CRX letter and the UD indicator is present on the account, research for a better address using: CC INOLE for the current posted entity information on the National Account Profile (NAP). CC ENMOD may reflect a recently input address change or a pending address change not posted to CC INOLE. Taxpayer's correspondence (if available). Use the following If/And/Then table to determine next actions: If And Then A new address is found The taxpayer has provided clear and concise notification of the address change Update the taxpayer's address using CC ENREQ. Input TC 972 with AC 661 using CC REQ77 to remove the UD indicator from the account. Issue the CRX letter following normal procedures. A new address is found The taxpayer has NOT provided clear and concise notification of the address change Do not update the taxpayer's address. Issue the applicable CRX letter to the new address. Include an open paragraph to advise the taxpayer of the information needed. Enclose Form 8822-B, Change of Address or Responsible Party - Business. A new address isn't found The UD indicator has not been reversed Issue the applicable CRX letter to the last known address. Include an open paragraph to advise the taxpayer of the information needed. Enclose Form 8822-B, Change of Address or Responsible Party - Business.

# Unpostable Category Codes and Names

3.12.166.5 (07-01-2021) Unpostable Category Codes and Names Every unpostable record for IMF, BMF, EPMF, PMF and CAWR is assigned a two-digit alpha-numeric Category Code. The unique two-digit alpha-numeric codes identify the area to work the unpostable case. The codes determine when a Form 4251 automatically generates. The codes determine if the case automatically sorts for an AUTO, MASS, or INDIVIDUAL type closure and if the case requires routing of unpostable document to the preparer or another function. The codes determine if the case is an expedite and/or requires special handling, the sequence in which the cases are sorted in order according to the recipient. The unpostable category codes, category names and Master Files that apply to EPMF are as follows: CATEGORY CODES CATEGORY NAMES MASTER FILE B4 Entity Control–EPMF Unpostables EPMF F3 Files Unpostables IMF, BMF, EPMF, PMF L5 All Others with Documents IMF, BMF, EPMF Refer to IRM 3.12.32.4, Category Code Identification and Criteria, for a complete list of Category Names and Codes.

# Unpostable Resolution Code Explanations

3.12.166.5.1 (07-01-2021) Unpostable Resolution Code Explanations Listed below are the Unpostable Resolution Code (URC) for CC UPRES. These codes are also valid on the EPMF Master File. URC EXPLANATION OF URC 0 No change made to the unpostable transaction. The information on UPRES will match the Master File. 2 Transaction to be deleted (voided). This URC creates a control base to the employee who input the unpostable transaction. 6 Changes Name Control and/or TIN and/or Plan Number and/or Plan Period, and adds Computer Condition Codes. 8 Transactions sent to the Reject Register or Error Resolution System (ERS) Suspense Status. Remarks are required when inputting a URC 8. A Correction of Name Control, using Master File Name Control. Valid on EPMF for 803. A URC A will convert and equal URC 6 when the unpostable record is updated. B Special closure made by the Unpostable-GUF. D Transaction to be deleted (voided) with no further action. No IDRS control base will be created. These Master File and URC combinations are subject to an additional validity check for each URC depending on the type of EPMF record and the unpostable category criteria. CC UPRES must meet all the validity checks for input of these URC actions as CC definers. See the general command code information for the CC UPRES validity criteria in IRM 3.12.32.

# Protection of Taxpayer/Filer Accounts

3.12.166.6 (01-01-2025) Protection of Taxpayer/Filer Accounts The greatest potential for unauthorized disclosure of tax information occurs when employees handle telephone inquiries from filers. Exercise special precautions to identify the filer or their authorized representative when answering such inquiries. All items on Form 5500 series returns are disclosable to the public. Form 5330 returns and Form 8955-SSA aren't disclosable to the public.

# Third Party Disclosure and Request for Information

3.12.166.6.1 (10-24-2022) Third Party Disclosure and Request for Information For issues regarding Disclosure, Third Party Request for Information, Freedom of Information Act requests, Privacy Act, etc. refer to IRM 11.3, Disclosure of Official Information. For specific questions regarding Disclosure and CAF, contact the local Campus Disclosure Office.

# EP Forms and Schedules

3.12.166.7 (06-13-2025) EP Forms and Schedules Form 5500, Annual Return/Report of Employee Benefit Plan: Schedule A, Insurance Information Schedule C, Service Provider Information Schedule D, Direct Filing Entity (DFE)/Participating Plan Information Schedule DCG, Individual Plan Information (see information below in paragraph 2) Schedule G, Financial Transaction Schedules Schedule H, Financial Information (Large Plan) Schedule I, Financial Information (Small Plan) Schedule MB, Multiemployer Defined Benefit Plan and Certain Money Purchase Plan Actuarial Information Schedule MEP, Multiple-Employer Retirement Plan Information Schedule R, Retirement Plan Information Schedule SB, Single–Employer Defined Benefit Plan Actuarial Information Note: Images of the Form 5500 and applicable schedules can be viewed at U.S. Department of Labor, Form 5500 series. In 2023, the Form 5500 was revised to add a new filing option – Defined Contribution Group (DCG) Reporting Arrangements. To be eligible to file as a DCG, all plans in the DCG must be individual account plans or defined contribution plans that have the same trustee; the same one or more named fiduciaries; the same plan administrator under ERISA and the Code; the same plan year; and provide the same investments or investment options for participants and beneficiaries. A Schedule DCG is used to report individual plan information. A direct filing entity (DFE) can file a single Form 5500 and include Schedule(s) DCG to satisfy reporting arrangements/requirements. A Schedule DCG can only be filed as an attachment to the Form 5500 (it can't be filed alone or with any other form). The Form 5500 is processed to the plan administrators (DFE) EIN and the Schedule DCG(s) are processed to the EIN on the Schedule DCG. The Schedule DCG will post as a TC 150 with doc code 30 to the EIN on the DCG. When researching the DOL/EFAST2 site with the EIN of the Schedule DCG filing, the result received will be the EIN and consolidated Form 5500. The Schedule DCG will be attached to that Form 5500 return (which can be used to obtain entity/return information if needed). Note: Schedule DCG unpostables are worked/resolved the exact same way as EFAST2 Form 5500 series unpostables. Refer to the appropriate UPC for resolution.

# Filing Requirements

3.12.166.8 (01-01-2026) Filing Requirements Plan modules have a plan filing requirement as follows: D = Form 5500, Schedule DCG T = Form 5500-SF (short form for Form 5500) X = Form 5500 Z = Form 5500-EZ 8 = Inactive N = Form 5500-SF filed in lieu of Form 5500-EZ Note: Effective January 1, 2021, Form 5500-SF can no longer be filed in lieu of Form 5500-EZ. Blank = Not required When the latest return module doesn't contain an unreversed TC 150 or 977, but does contain a TC 591, 593, 595, or 596, the plan filing requirement is blank. Other possible transactions and their results are: A TC 150 or 977 and one of the following transactions: TC 591, 593, 595, or 596 and assets haven't been distributed, the plan data module has a plan filing requirement and a plan status code. A TC 151, 591, 593, 595, or 596 and no TC 150 or 977, the plan filing requirements is blank and the plan status code is zero (0). A TC 150 or 977 and assets have been distributed, and no participants are present, the plan filing requirements is blank and the plan status code is zero (0). A TC 150 or 977 and one of the following transactions: TC 591, 593, 595, or 596 and assets have been distributed, the plan filing requirements is blank and the plan status code is zero (0). A TC 150 or 977 and the assets haven't been distributed, the plan data module has a plan filing requirement and a plan status code. Condition Code F, the plan filing requirement is blank and the plan status code is zero (0). Note: The entity filing requirements (FR) contains a 1 for each type form present. If several plans have the same FR, the entity FR only reflects 1 for that type return. To post a TC 020 to the entity module, all plan filing requirements must be blank and the entity filing requirements must be zero (0) or (8).

# Filing Requirements for Final Returns

3.12.166.8.1 (07-01-2021) Filing Requirements for Final Returns When the latest return module contains an unreversed TC 150 or 977 with Computer Condition Code (CCC) "F" (final return), the plan filing requirement is blank. CCC "F" generates on current year Forms 5500/5500-EZ if Return Process Code (RPC) "T" is present. Note: CCC "F" is input on "fact of filing" Forms 5500 if Part I, Line Item B (3) is checked "YES" . CCC "F" is input on "fact of filing" Forms 5500-EZ if Part I, Line Item A (3) is checked "YES" . The RPC "T" generates when: Schedule H/I Line 5a is answered "YES" , and Total end-of-year assets is zero, and Total participants end-of-year is zero. Note: RPC "T" generates on pure fringe benefit plans if Form 5500 Part I, Line Item B (3) is checked, and Line 6 on the Schedule F is checked "YES" .

# Filing Requirements for Plan Changes Due to Takeover or Sale

3.12.166.8.2 (07-01-2021) Filing Requirements for Plan Changes Due to Takeover or Sale Use the following instructions to update the old sponsor's filing requirements when: A change in sponsorship occurs due to a takeover or sale, and A final return isn't filed or the plan's sponsor has changed, but No assets or liabilities were transferred to another plan, and The plan hasn't terminated or merged with another plan. If Line 4 a, b or c is completed on Form 5500 (Line 5 a, b or c on Form 5500–EZ), or contact with the filer indicates a change in sponsorship has taken place, then: Research to determine if the filing requirements for the EIN and plan number for the old sponsor (indicated on Line 4 b or by contact with the filer) were deleted. If the filing requirements are blank or 8, take no action on the old sponsor's account. If active filing requirements are present, input a TC 591 closing code (cc) 097 to the old sponsor's account using the tax period ending on the return. Caution: If a TC 150 is present on the module, a TC 591, 593, 595, or 596 posted to the same module won't turn off the filing requirement. TC 59X must be input on the next module to make the FRC blank. When a TC 020 (Doc Code 64) posts to the plan data module, the plan filing requirement is 8 if a TC 12X or return module is present for the plan. If there's no TC 12X or return module present, the plan module will be erased. No transactions post to a plan with a TC 020 (Doc Code 64) except a TC 012.

# Sequence of Accounts on the EPMF

3.12.166.9 (07-01-2021) Sequence of Accounts on the EPMF Accounts on the "EPMF" are maintained in EIN and Plan Number sequence (NNNNNNNNN–NNN).

# Plan Number

3.12.166.10 (07-01-2021) Plan Number A plan number is a three-digit number assigned by the plan sponsor to differentiate between plans which are, or may be, established or maintained by the same plan sponsor. The table below shows the range of plan numbers associated with the plan type: If the Plan is a Then the Plan Number starts with Pension Plan/Profit Sharing 001–500 Welfare Plan 501–999 Fringe Benefit Plan 501–999 Direct Filing Entity (DFE) 001–500 Group Insurance Arrangement (GIA) 501–999 Multiple-employer Plan (Other) plan 333–339 (Pre EFAST Only) Once assigned, use the same number consistently to identify the same plan. If a plan terminates, don't use the plan number for any new plan. The plan number along with the plan name identifies a plan from other plans for a given sponsor. The plan name, plan number, the type of return filed, and the plan ending month make up the plan entity. As long as the plan is in effect, the plan name and plan number must stay the same. Exception: If the sponsor initiates updates or changes to the plan name and as long as the characteristics (e.g., assets, plan beginning date, etc.) for the plan remain the same, a new plan number won't be assigned due to minor changes in the plan name.

# Plan Data Module

3.12.166.10.1 (07-01-2021) Plan Data Module The plan data module contains information related to one plan number. Some of the information included is: Plan name (research CC EMFOL definer L) Effective date (research CC EMFOL definer L) Type of plan (research CC EMFOL definer L) Administrator name, address, and EIN (research CC EMFOL definer D)

# Plan Data Module Transactions

3.12.166.10.2 (07-01-2021) Plan Data Module Transactions The plan data module can be established or updated with the following transactions, input via CC EPLAN: TC 000 – Establishes a plan TC 011 – Changes the plan number/consolidates two plans TC 012 – Reactivates a plan number TC 013 – Changes the plan name TC 016 – Changes plan filing requirements TC 017 – Changes the file folder number (not used in campus processing) TC 020 – Deletes a plan number TC 053 – Changes plan year ending month TC 127 – Changes or adds administrator data TC 128 – Changes both the plan name and administrator data with one transaction and can change Effective Date The plan data module can be updated with the following transactions, input via CC FRM77 (Doc. Code 77): TC 122 – Reverses a plan application (TC 121/123) TC 126 – Reverses a plan termination (TC 125) The plan data module can be established or updated by the following transactions, input via Cincinnati Area Office (AO) EACS: TC 121 – Establishes a plan TC 123 – Establishes or updates a plan TC 125 Doc. Code 10 – Posts a plan termination. Note: This transaction doesn't terminate plan filing requirements. TC 125 Doc. Code 11 – Posts the date of a merge in MMDDYY format. The plan data module may also be updated via vendor or IRS processing: TC 150 – Return posted TC 977 – Amended return posted

# Input of EPLAN Transactions

3.12.166.10.3 (07-01-2021) Input of EPLAN Transactions CC EPLAN transactions validate the input EIN, name control and plan number against the NAP. If the EIN on the input transaction isn't established on Master File, an error message generates. Establish the EIN using CC ENREQ/BNCHG before inputting the EPLAN transaction. The name control used on the CC EPLAN transaction must match the name control on Master File. If inputting a CC EPLAN transaction (other than a TC 000), establish the plan number on the Master File or an error message generates. The input format for CC EPLAN is EPLAN with definer "R" , the sponsor EIN with File source "P" , the name control, and the plan number. Enter an intent indicator (INTENT–IND) "Y" if the transaction is a TC 000. INTENT–IND "N" automatically generates when a "Y" isn't used. Don't access CC ENMOD before inputting a CC EPLAN transaction. If a TC 000 is input to a plan number that already has a pending TC 000 on the account, an error message ("TC 000 PENDING FOR THIS PLAN-NUMBER" ) generates on the EPLAN screen. Deleted TC 000s (DU, DN, DQ, etc.) are also recognized by the program as pending transactions. If receiving an error message on input of a TC 000, research CC ENMOD. If the original transaction was deleted, and research indicates that a TC 000 is necessary for the plan, overlay the TC 000–ADD–INDICATOR "N" with a "Y" . Input the rest of the transaction as usual. This overrides the error. Note: Master File usually generates TC 000 as a result of an EFAST processed return.

# Plan Data Module Administrator Information

3.12.166.10.4 (07-01-2021) Plan Data Module Administrator Information When inputting a TC 000 via CC EPLAN, enter the administrator name, address, and Administrator's Identification Number (AIN) or the Administrator Same Indicator (ASI). If the return indicates that the administrator name, address, and AIN are the same as the sponsor's, enter "1" in the ASI field. Don't use the literal word "SAME" for the administrator information. If using the ASI, don't enter the administrator name, address, and AIN. If no AIN is present, but administrator name is present on the unpostable document, research BMF and EPMF for a number. The administrator's number may be established on the BMF only or both the BMF and EPMF. The administrator's number doesn't need to be established on the EPMF. If an AIN is found, input the TC 000 and close the unpostable. Exception: On Form 5500–EZ (Pre-EFAST), enter "1" in the ASI field unless Box 2a is checked "NO" , and the filer wrote the administrator information on the back or in the margin of the form. Revised Form 5500-EZ provides space for the administrator's information. Administrator information for Form 5500 can be found in Part II of the ERTVU record. If the filer checked "NO" for Box 2a but didn't furnish the address, research for an address. If the address is the same as the one shown in Box 1a, enter a "1" in the ASI field. If different, input the administrator address on the EPLAN screen.

# Plan Applications – Forms 5300, etc.

3.12.166.10.5 (07-01-2021) Plan Applications – Forms 5300, etc. In some cases, sponsors of employee benefit plans file applications for determinations and terminations for their plans. These applications post to the EPMF as TC 121, 123, or 125, input by Cincinnati. TC 12X transactions reflect the effective date of the plan, termination, or merge, plan name, plan number, and certain other characteristics of the plan. The plan data module can be updated with the following transactions, input via CC FRM77 (Doc. Code 77): TC 122 – Reverses a plan application (TC 121/123) TC 126 – Reverses a plan termination (TC 125) The plan data module can be established or updated with the following transactions, input via Cincinnati Area Office (AO) EACS: TC 121 – Establishes a plan TC 123 – Establishes or updates a plan TC 125 Doc. Code 10 – Posts a plan termination Note: This transaction doesn't terminate plan filing requirements. TC 125 Doc. Code 11 – Posts the date of a merge in MMDDYY format

# Transactions and Document Codes

3.12.166.11 (06-13-2025) Transactions and Document Codes Form 5500 series return posts with Transaction Codes 150, 156, and 977 (amended return) or TC 154 for Form 5330 fact of filing. Forms 5330 process as a BMF return after January 1, 2001 (MFT 76, Tax Class 4). Before January 1, 2001, the assessments were made on ANMF. The valid Document Codes (4th and 5th digits of DLN) are as follows: Document Document Code Transaction Codes Form 8955–SSA and Schedule SSA without primary return 36 977, 155, 156 Form 5500 and Fact of Filings 37 150, 977, 154, 155, 156, 976 and 446 Form 5500 Schedule DCG 30 150, 977, 154,155, 156,976 and 446 Form 5500–EZ and Fact of Filings 31 150, 977, 154, 155, 156, 976 and 446 Form 5500–SF 32 150, 977, 154, 155, 156, 976 and 446 Form 3177 (Notice of Action for entry on Master File) 77 or 49 151, 420, 421, 424, 428, 474, 475, 930, 932 Examination (AIMS) 47 or 77 300, 301, 420, 421, 424, 560 for Form 5330 and 420, 424, 560 for Form 5500 Form 5596, TE/GE Non-Examined Closings 47 or 77 421 Form 5597, TE/GE IMF/BMF/EPMF Request 47 or 77 424 Form 5599, TE/GE Examined Closing Record 47 or 77 160, 161, 270, 271, 300, 301, 340, 341 and 421 Form 5650, EP Examined Closing Record 47 or 77 421 and 560 Delinquent Tax Period 14 or 49 141, 142, 59X CAF 77 960, 961, 962 Form 5330 35 or 76 150, 154, 460/620, 973 Form 5558 for Form 5330 (prior to January 1, 2024) 77 460/620 Form 8868 for Form 5330 (starting January 1, 2024) 77 460/620 Form 5558 for Form 5500 series 55 460 Form 5558, Application for Extension of Time to File Certain Employee Plan Returns. Approved extensions will post to the EPMF for Form 5500 series returns. If a Form 5500 series return appears to be late, research the BMF using CC BMFOL and the IMF using CC IMFOL. Determine if a TC 460 posted to an account that the plan sponsor reported the income tax for the business associated with the plan that has the same return year as the 5500 series return. As of January 1, 2024, Form 8868, Application for Extension of Time to File an Exempt Organization Return or Excise Taxes Related to Employee Benefit Plans, must be filed to request an extension of time to file the Form 5330. To be eligible for the extension, Parts I and II must be completed, any balance due paid, signed under penalties of perjury and timely filed. Forms 8868 and Forms 5558 for Forms 5330 post to the BMF with a TC 460/620. Note: Form 8868 extension (TC 460/620) unpostables are worked/resolved the same way as Form 5558 (TC 460/620) unpostables. The only difference is the form the extension request is being filed on. Beginning January 1, 2025, the Form 5558 can be electronically filed through EFAST2; however, EFAST2 is unable to accept payments. Since payments can be made with a Form 5330 extension request, the Form 5330 section on the Form 5558 needed to be moved to a form that can be filed with payments. Therefore, the entire Form 5330 section was removed from the Form 5558 and added to the Form 8868. The extension request is processed the same.

# Research Information, Methods and Tools

3.12.166.12 (07-01-2021) Research Information, Methods and Tools IDRS Command Codes that create posting transactions have their TIN and name control combinations validated before the "Request Completed" response. These transactions pass against the Taxpayer Identification File (TIF) and the National Account Profile (NAP) to ensure that the transaction posts properly to the Master File. Note: If an EIN is located on the BMF only, establish it on the EPMF to avoid unpostable code 801. Ensure correct closure of EPMF unpostable cases using proper research. Perform research using several sources provided in the following sections.

# Master File Research

3.12.166.12.1 (07-01-2021) Master File Research Research the EPMF using CC EMFOL and ERTVU. Research Master File entity data for both BMF and EPMF using CC INOLE. Research the EPMF Return Transaction File using CC ERTVU. See IRM 3.12.166.12.7, Command Code ERTVU.

# CADE2

3.12.166.12.2 (07-01-2021) CADE2 The Customer Account Data Engine (CADE) 2 Program Office in Headquarters is charged with the primary goal to implement a single, modernized programming solution which provides daily processing of taxpayer accounts. The CADE 2 solution is comprised of several components to modernize the IRS to a daily processing environment with several Transition States. With CADE 2 there were changes to campus cycles that began with cycle 201201. The BMF, EO and EPMF campus cycles are: Campus Cycle: Thursday – Wednesday Master File Processing: Friday – Thursday Notice Review Saturday: Monday (8+ days) Unpostables: New available Tuesday; Closing Tuesday BMF, EO and EPMF transaction posting time frames are as follows: Transactions are viewable using CFOL command codes on Saturday following the weekly Master File processing run on Thursday. Transactions are viewable as posted transactions using IDRS command codes on Monday following the weekly Master File processing run on Thursday. Note: With the acceleration of the IDRS weekly analysis being performed the weekend directly after the Master File processing on Thursday, transactions post instead of being in pending status on Monday. Cycle posting dates reflect a format of YYYYCCDD. YYYY indicates the year. CC indicates the posting cycle. For IMF transactions, the following values for DD are defined: 01 = Friday 02 = Monday 03 = Tuesday 04 = Wednesday 05 = Thursday Note: BMF, EO and EPMF cycle posting dates on BMFOL continue to reflect YYYYCC. YYYY indicates the year. CC indicates the posting cycle. BMF cycle posting dates in TXMOD reflect a format of YYYYCCDD. The DD value is 08.

# Integrated Data Retrieval System (IDRS) Research

3.12.166.12.3 (07-25-2024) Integrated Data Retrieval System (IDRS) Research IDRS is a computer system with the capability to retrieve and update stored taxpayer account information on the Master Files. Perform research of IDRS through the use of various command codes (CC). IDRS research is necessary to see case control information and pending transactions that have yet to post to Master File. IDRS research command codes are: NAMEE/NAMEB: search for an EIN. The filer's name must be known to research for an EIN. EMFOL: research posted Employee Plan Master File information.

# National Account Profile (NAP) Research

3.12.166.12.4 (07-01-2021) National Account Profile (NAP) Research Research the NAP using CC INOLE to display current Master File information. Use CC INOLE with definer "T" to determine if the TIN is on more than one Master File. CC INOLE with definer "S" , for EPMF accounts, displays the sponsor name, mailing address, location address, name control, and prior name control. It also displays up to five plan numbers, with the plan name, administrator EIN, plan year ending month, effective date, filing requirement, and status code. Note: To access an EPMF account, include a "P" after the EIN. Use CC INOLE with definer "P" for plan information for a filer with more than five plans. When inputting INOLE definer "P" with no plan number, the first ten plans of the account display. If the message "MORE-PLAN-DATA" displays, enter the highest plan number you have on the screen and the next ten plans display. The sponsor name and address doesn't display with this definer. The same plan data displayed with definer "S" displays up to ten plans on a page, along with the sponsor EIN and name control. Use CC INOLE with definer "G" when the TIN type is unknown

# Generalized Unpostable Framework (GUF) Research

3.12.166.12.5 (07-01-2021) Generalized Unpostable Framework (GUF) Research Perform GUF research by use of Unpostable command codes. The Unpostable command codes are: UPTIN: displays all open unpostables for a specific TIN and maintains the unpostable file for display purposes for 90 days after closing. UPBAT: batch (mass) close non-RPS unpostable cases. UPASG: assign or reassign an unpostable case or group of unpostable cases. UPCAS/UPCASZ: suspend a case, request research, order missing documents and add history items to the screen display. UPDIS/UPRES: valid for all Master Files, displays an unpostable record and closes (corrects) a case. See IRM 3.12.166.5.1, Unpostable Resolution Code Explanations, for unpostable resolution codes. If there's no activity on a tax module for ten years or more, the tax module drops from the Master File. If there's no activity on a plan module for ten or more years and there are no related tax modules, or all tax modules drop , the plan module drops. If there's no activity for ten years or more on an entity module and there are no related plans or all related plans dropped per (a) above, the entity drops. The entities must be established before any transactions will post. CC FINDE with definer code D may have information on these accounts.

# Command Code EMFOL

3.12.166.12.6 (06-13-2025) Command Code EMFOL Use CC EMFOL to research posted EP Master File information. This file updates weekly as the Master File itself updates. See IRM 2.3.64, Command Code EMFOL, for more information on input and usage of this command code. Input the sponsor EIN with a definer to access the command code. The type of information required determines the definer used for the request: Use definer "I" to view an index. The index displays all plan numbers, plan names and tax periods on the record for a particular sponsor EIN. This screen also indicates whether a TC 150 posted for a particular plan number and plan period and whether there's a record on CC ERTVU for the return. It also reflects the schedules attached to the posted return. Use definer "E" to view the Filer Entity Screen. This screen displays the sponsor name and address, name control, CAF indicator and all transactions (TC 000, 011, 012, etc.) associated with the sponsor's entity module. This screen also displays the prior primary name for name change transactions and XREF EIN for account consolidations. Use definer "L" with a plan number to view the Plan Data Screen. Use this screen to research all entity information associated with the plan itself: the plan name, effective date, type of plan, filing requirements, sponsor phone number, etc. Also use this screen to research data on the plan application and plan termination as well as all transactions associated with the plan entity module. Use definer "D" with a plan number to view the Plan Administrator Screen. Use this screen to research the administrator EIN, name, address, and telephone number associated with a particular plan. Use definer "T" with a plan number and plan period ending to view the Tax Module Screen. This screen displays the controlling DLN and all transactions associated with a particular tax module, including TC 151 and TC 154 information. Use definer "S" with a plan number and plan period ending to view the Status History Screen. This screen displays the historical status of the tax module. Use definer "H" to view a Help Screen with valid input entries and definer codes. Use definer "C" to view the EPMF Last Reported Data screen. This screen displays the cross reference information for any EIN that has been entered on Line 4b on Form 5500. The screen displays the DLN, EIN, plan number, tax period, and new plan number. Use definer "X" to view cross reference module information. This screen displays Cross Reference EINs (no Plan Number or Tax Period). An EIN Plan Number will result in the display of the Cross Reference EINs and Cross Reference Plan Numbers (no Tax Period).

# Command Code ERTVU

3.12.166.12.7 (06-13-2025) Command Code ERTVU The EPMF Return Transaction File On-line (ERTVU) system provides read only access to Form 5500 return data and accompanying schedules. See IRM 2.3.65, EPMF Return Transaction File On-Line (ERTVU) Research, for more information on input and usage of this command code. Use CC ERTVU when researching EPMF accounts. Command Code ERTVU is input using an EIN, Plan Number and Tax Period. A one digit definer code is used for all Schedules. Screen positions 1 through 26 are used for Command Code input. The EIN will be edited on input (i.e. NN-NNNNNNN). No definer code is needed for Form 5500, Form 5500 Schedule DCG, Form 5500-EZ or Form 5500-SF; however, a space is required in position 6 of the input request. If any required field is invalid a HELP screen will be displayed. Note: Requests for processing year 2000 or later data (EFAST) will require a Return Status Code in position 17. The Document Locator Number (DLN) can also be used with CC ERTVU to request a document processed by EFAST. The Return Status Code will be required in position 24 on this type request. Valid definers are: Use a blank definer for Forms 5500, 5500–SF and 5500–EZ. The first page of each return screen contains the information from the Edit Sheet, a line number index, and a list of what schedules are present for that return. Use definer "N" for an index or all returns and schedules for an account. Use definer "L" to view a Help Screen with valid input entries and return status codes. Use definer "A" to view Schedule A (for 1993 and later returns). Use definer "B" to view Schedule B (until PY 2009/2011). Use definer "B" to view Schedules MB & SB (PY 2009 and later).

Repeat unpostable cases – The cycle of the "First Time Unpostable Case" appears. 11 – REP Repeat indicator – "R" appears on repeat unpostable cases. 12 – ST Unpostable Status Code Blank – Not assigned A – Assigned, not corrected C – Corrected, not removed from SCUPMF H – Quality review hold S – Suspense Q – Accepted by Quality Assurance 13 – Unpostable status date Date of the last change in status 14 – Document Locator Number (DLN) Unique number assigned to every processed return used to control, identify and locate a document 15 – MF-AO – Master File primary location code Taxpayer's current area office location code 16 – Taxpayer Identification Number (TIN) Identifies the TIN that is currently unpostable 17 – TIN TYPE TIN TYPE 0 – Valid SSN 1 – Invalid SSN 2 – EIN 3 – Dummy TIN (default) 4 – Taxpayer representative TIN 5 – Document 18 – TXPD Tax period 19 – MFT Master File tax code 20 – PN Plan Number 21 – TC Transaction Code 22 – Date Transaction Date 23 – NC Name Control/check digit 24 – STC Secondary Transaction Code 25 – IDRS EMP Employee number of the originator of an unpostable IDRS input document 26 – Literal XTIN or XSEQ Literal XTIN or XSED 27 – DOC CC Document condition code — Computer codes from the document 28 – UPCASZ Correction information 29 – Master File data Master File data or miscellaneous data from the unpostable record 30 – Message The message "Other CASES WITH THE SAME TIN ON UPTIN" appears if UPTIN displays at least one other open or closed unpostable case. *** REL CYC Release cycle – corrections are delayed from 1–6 weeks when closed with a future posting cycle in the REL CYC field. UPRES closed cases drop from IDRS after the weekly update run unless a release cycle was entered. Use CC UPRES to close single unpostable cases. In order to save keystrokes, UPRES automatically appears when requesting an UPDIS display. Close a case by entering the appropriate URC in the first space following CC UPRES. Enter items to be corrected on lines 5 and 7. Line 8 is designated for "Remarks" . Cases closed using UPRES leave SCUPMF when the weekly tape runs. A closure may be delayed up to 6 weeks by inputting a future posting cycle in the release cycle (REL CYC) field. The case remains on SCUPMF and any erroneous closures can be corrected during that time. To assist the tax examiner, error messages display when an invalid entry is made. The following fields are on the UPRES record: 1 – Unpostable Resolution Code (URC) – Includes 0, 6, or D. 2 – Definer Modifier Code B – Allows GUF to bypass the NAP check on URC 0 and URC 6. 3 – Taxpayer Identification Number (TIN) – Corrected TIN is entered. 4 – Tax period ending – The corrected tax period ending in YYYYMM format is entered. 5 – Plan Number – The corrected plan number is entered in this field. 6 – Name Control – The corrected name control is entered in this field (never enter a check digit). 7 – CC – Computer condition code – Adds a computer condition code to the UP record. 8 – Remarks – Indicates the type of research or procedure used to resolve the case. For example, "Per NAMEB/INOLE" or "TC 013 Input" . 9 – REL CYC – Releases an unpostable correction in a later cycle. 10 – DOC CC – Document computer condition code – shows the CCC condition codes input to the return or document (for example, CCC G for an amended return). This CC can't be removed or deleted from the UPRES screen. The resolution of the unpostable case may require an update to the Master File in order to correctly post the return and to avoid repeat unpostables. There are times when an input transaction or the unpostable must be cycled to be input at different times.

# Command Code UPTIN

3.12.166.12.11 (07-01-2021) Command Code UPTIN Use CC UPTIN to display all open unpostables for a specific TIN. The unpostable displays for 90 days after the case closes. The UPTIN record updates daily and shows the action taken to resolve the unpostable, the URC and the correction. The following fields are on the UPTIN record: 1 – Unpostable sequence number 2 – Functional area code 3 – Unpostable code and reason code 4 – Original unpostable code 5 – Unpostable resolution code 6 – Unpostable status code and date 7 – Employee number assigned/resolved 8 – Unpostable DLN 9 – Corrected name control 10 – Correct EIN 11 – Corrected plan ending 12 – Corrected plan number

# Transaction Code 151

3.12.166.13 (07-01-2021) Transaction Code 151 The IRS uses this transaction code to move a posted TC 150/976/977 to a different module when someone/the system determined that the return posted incorrectly. The IRS also uses this transaction code to reverse a posted TC 154/155/156 and by EFAST to reverse a posted EFAST 150/155/156/976/977. TC 151 has a filing location code (FLC) 29 – OSPC. Note: Check for any IDRS open controls before taking any action. If an open control is present, contact the employee with the control. If both a TC 150 and a TC 977 posted to the same module, a TC 151 moves the return with a DLN that matches the TC 151 Reversal DLN. If both returns should move, two TC 151 transactions must be input. Before inputting a TC 151, research to determine if the return module contains an unreversed TC 420 or 424 indicating that the return is under audit (being examined). If so, fax a request to (410) 962–0650: AIMS Coordinator ESS RM 1542 31 Hopkins Plaza Baltimore, MD 21201 Returns under audit can't be moved. An IRS TC 151 that attempts to move a return under audit unpost as an UPC 851. Before inputting a TC 151 to reverse a TC 150 or TC 977, research CC EMFOLT. Use the EMFOLT information and/or a copy of the filed return as documentation for the transaction. Note: The IRS can input a TC 151 to move an EFAST return to a different module, using CC EMFOLT information.

# Mismatched Reversal DLN For TC 151 (Pre EFAST)

3.12.166.13.1 (07-01-2021) Mismatched Reversal DLN For TC 151 (Pre EFAST) When the Reversal DLN in the input TC 151 doesn't match the Control DLN in the tax fixed section, the transaction unposts as a UPC 851. CC FRM77 for REV–DLN must have a valid 14-position DLN for EPMF with the first five positions as follows: The first two digits must be a valid campus code. The third digit must be 0 (zero). The fourth and fifth digits must be 30, 31, 35, 37, 38 or 47.

# Cross Reference Fields For TC 151 (Pre-EFAST)

3.12.166.13.2 (07-01-2021) Cross Reference Fields For TC 151 (Pre-EFAST) Cross reference fields PN, TIN, TXPD and 971/151 CD are valid with TC 151. Input the proper cross reference field as indicated by the 971/151 CD. Input the XREF–PN if the 971/151 CD is 20, 23, 24, 25, 26, 29, 30, 31, 32, 35, 36, or 37. Input the XREF–TIN if the 971/151 CD is 22, 24, 25, 28, 30, 34, 36, or 37. Input the XREF–TXPD if the 971/151 CD is 21, 23, 25, 27, 31, 35, or 37. Input the XREF–PN, TIN, and TXPD if the 971/151 CD is 19.

# Alternatives to TC 151

3.12.166.14 (07-01-2021) Alternatives to TC 151 If an EFAST-processed return posts to an incorrect module, follow the instructions below: If Then An unpostable is resolved with URC "D" because we are unable to post the return to the correct module Input TC 590 cc 097 on the module where the return should've posted. An unprocessed return or copy is received from the taxpayer Forward the return to the EP Entity Department using local procedures.

# Filer Contact and Correspondence

3.12.166.15 (07-01-2021) Filer Contact and Correspondence Filer contact is an important part of unpostable resolution. Unpostables can utilize phone calls and letters in order to expedite the resolution of an unpostable. Follow the instructions in this section on all unpostables when filer contact is required.

# Telephone Contact

3.12.166.15.1 (07-01-2021) Telephone Contact When at all possible, make a phone call before writing a letter. Use a correspondex letter when: A telephone number can't be found. If after at least two attempts the sponsor/administrator can't be reached by phone. When the phone call is successful, follow-up the phone call(s) with a letter confirming the conversation and action(s) taken, if necessary.

# Written Correspondence

3.12.166.15.2 (07-01-2021) Written Correspondence When a letter is necessary, use CC UPCASSC to suspend the case while waiting for a response. If a response isn't received within 40 days (30 days indicated in the letter to the filer and 10 days purge time), close the case according to available information. Exception: Overseas filers have a 70 day purge time.

# C–Letters

3.12.166.15.3 (07-01-2021) C–Letters The following letters are commonly used when resolving EP unpostables (however, other letters may be used). Input them via IDRS (CC LETER). 1072C - Employee Plan EIN Missing/Requested/Assigned 3938C - Form 5330 Incomplete for Processing

# Late Replies to Correspondence

3.12.166.15.4 (07-01-2021) Late Replies to Correspondence If a reply from the filer is received after the unpostable case is closed and it contains information that can be used to correct the filer's account, prevent subsequent unpostables, or request further action from the IRS, correct the filer's account and respond as appropriate. If correspondence is received from the filer regarding penalties, route it to EP Accounts, Mail Stop 6552. See IRM 3.13.36, EPMF Account Numbers, for information on where to route additional attachments to correspondence. If the taxpayer states they're in a hardship situation and immediate relief is unable to be provided, the case may meet TAS hardship criteria. Refer to IRM 21.7.1.3.1, Taxpayer Advocate Service (TAS), or IRM 13.1.7.2, Introduction to TAS Case Criteria.

# Plan Name and Plan Number

3.12.166.16 (07-01-2021) Plan Name and Plan Number The plan number is a three-digit number assigned by the plan sponsor to differentiate between plans established and maintained by the same sponsor. Pension plans are numbered consecutively from 001 to 500. Welfare and fringe benefit plans are numbered consecutively from 501 to 999. If the sponsor has more than 500 of either type of plan, a second EIN is assigned. On IDRS, "Second EIN for Plans" appears in the sponsor entity area. Plan number 333–339 is a special number used to identify a Pension Benefit Plan of a Multiple-employer Plan (Other) plan. If Part II, Box 8a is checked and 333 (or higher number is a sequence beginning with 333) was previously assigned to the plan, the number may be entered on Line 1b. (Pre-EFAST only). Once assigned, the same plan number must consistently be used to identify the same plan. If a plan terminates, don't use the plan number for any new plan. Instead, use the next available higher number for the new plan. Each plan maintained by a plan sponsor has a plan name as well as a plan number. The name, plan number, effective date, plan assets, type of plan, and plan year ending all help identify a particular plan. Unpostables must be able to correctly identify a plan before inputting any entity changes, or making any changes to plan data on the return. The plan name, plan number, and plan effective date should be the same each year that a return is filed.

# Plan Name Changes

3.12.166.16.1 (07-01-2021) Plan Name Changes What may appear to be a new plan or a change in the plan name may not actually be a change. The filer may reverse the order of the name or use abbreviations or full names versus initials. For more information on Plan Names see IRM 3.13.36, EPMF Account Numbers. The following are some examples: JIM SNOW PROFIT SHARING PLAN/J. SNOW P–S PLAN. RETIREMENT PLAN FOR A. TREE INC/A. TREE INC. RET. PLAN. JOHN SEA SERP/SELF EMPLOYED RETIREMENT PLAN JOHN SEA. A direction from EP Determinations instructs tax examiners to leave the words "The" and "DBA" in the primary name line. There is no filer impact and the account doesn't need to be changed. Other plans with name differences may appear to be the same plan, but aren't: JIM SNOW PENSION PLAN "A" /JIM SNOW PENSION PLAN "B" . A. TREE P–S TRUST/A. TREE & SONS P–S TRUST. PENSION PLAN FOR HOURLY EMPL/EMPLOYEES PENSION PLAN. Compare plan assets and the type of plan as well as the plan name to determine if the plan on the document is the same as the plan on the Master File. The end-of-year assets from the previous plan period (from Master File research) should match the beginning-of-year assets on the document, for a pension or profit sharing plan. The type of pension plan on Master File may match the type of pension plan on the document. Welfare plans can change plan types from year to year. The plan effective date is also means of identifying the correct plan. Even if the plan names appear to be the same, if the type of plan or plan assets mismatch, research the account. If after thorough research you're still unable to correctly identify the plan, initiate contact with the filer. The following tables list the Entity and Fringe Benefit Plan Codes. Entity Codes Definer Definition 1 Multi-employer Plan 2 Single-Employer Plan 3 Multiple-employer plan 4 Direct Filing Entity (DFE) Fringe Benefit Plan Codes Code Definition A Code Section 125 – Cafeteria Plan B Code Section 127 – Education Assistance Program C Code Section 137 – Adoption Assistance See the Form 5500 instructions for Plan Characteristic Codes reported on Lines 8a and 8b. The codes can be found on CC EMFOL using definer code P. For more information on CC EMFOLP see IRM 2.3.64, Command Code EMFOL.

# Plan Number Discrepancies

3.12.166.16.2 (07-01-2021) Plan Number Discrepancies If a plan number was established erroneously on the EPMF and doesn't have any return modules posted, it can be deleted. Input a TC 020 with CC EPLAN. Note: DON'T input a TC 020 without the EP manager's approval. Don't attempt a change to the plan name or plan number unless it's a Service's error. Otherwise the filer should notify IRS when there's a change. Always process Forms 5500–EZ using a plan number in the 001–500 series. Never correct the plan number to a number greater than 500. If a welfare plan number was assigned to a pension plan, input a TC 011 using CC EPLAN to change the plan number to the next available number in the 001–500 series.

# Types of Employers or Sponsor

3.12.166.16.3 (07-01-2021) Types of Employers or Sponsor The following section provides background information needed to determine if an employer/sponsor is or isn't required to file a return. Single-employer plan – This is the most common type where one employer adopts or establishes a plan for their employees. One return should be filed annually. Banks or trust companies often prepare these returns. If Then Research identifies a Bank or Trust company is using their EIN to file for Single/Individual Employer plans, research for the Single/Individual Employer's EIN, if found Close the unpostable with URC 6 with the correct EIN to post the return. Send a Letter 1072C to the bank, trust company or employer using the prepared paragraph, explaining they have filed the Form 5500 incorrectly. Correspond with the filer using Letter 1072C notifying them of their new EIN. An EIN can't be found and the information provided belongs to the bank Research IDRS using CC IRPTR or CC NAMES to obtain the filer's information. ESIGN an EIN, establish the plan using plan number 001 and the information provided on CC IRPTR or CC NAMES. Suppress the notice. Correspond with the filer using Letter 1072C notifying them of their new EIN. Multiemployer Plan – This is a plan in which more than one employer participates. It involves collectively bargained agreements between one or more employee organizations and more than one employer. Participating employers don't file individually for these plans. If Then The filer filed Forms 5500 as a multiemployer plan and through research it's discovered the organization filed returns for each participating employer Send Letter 1072C using the multiemployer plan paragraph, asking the filer to correct their return. Suspense the unpostable for 45 days. When the corrected return is received, verify the information provided on the return and that a Schedule T is attached for each participating employer is attached. Close the unpostable with URC D. Input a TC 591 cc 097 on each account to satisfy the module. Send the return to the EP Entity Department to forward for processing. No reply or insufficient response Close the unpostable with URC D. Group Insurance Arrangements a Type of DFE – This is an arrangement whereby benefits are provided to the employees of two or more unrelated employers. The plan is fully insured and uses a trust to hold the assets. Only one annual return is required to be filed by the administrator. If a consolidated report isn't filed, then each participating employer must file. If Then Research indicates the administrator is filing multiple returns on the same EIN and plan number for different plan periods Correspond using Letter 1072C asking the filer to correct the filing by consolidating the return or having each participating employer file. Suspend the unpostable for 45 days. When the corrected return is received, verify the information as a consolidated return or returns filed for each employer. Close the unpostable with URC D. Input a TC 591 cc 097 on each account to satisfy the module. Send the return to the EP Entity Department to forward for processing.

# Centralized Authorization File (CAF) Unpostables

3.12.166.17 (06-27-2024) Centralized Authorization File (CAF) Unpostables The Centralized Authorization File (CAF) is operational on EPMF. The CAF transactions are: TC 960 – Establish the CAF record on the Master File. TC 961 – Reverse TC 960. TC 962 – Update TC 960 data already posted.

# Posting Delay Code

3.12.166.18 (07-01-2021) Posting Delay Code When multiple transactions are required to adjust an account and some must post in later cycles than others, use a Posting Delay Code (range 1–6) with the transactions to be cycled. The action to post these transactions to the Master File will defer until the indicated number of cycles passes. The tax examiner determines the required number of delay cycles with respect to the first transactions to post. The following IDRS transactions provide the posting delay capability: ADJ54 (Doc. Code 54) INCHG, BNCHG, BRCHG, EPLAN AND EOCHG (Doc. Codes 50, 53, 63, 64, 80, and 81) DRT24, DRT48 (Doc. Codes 24 and 48) FRM34 (Doc. Code 34) FRM77 and FRM7A Form 5599 and Form 5650 (Doc Code 47) The Posting Delay Code isn't posted with the transaction or shown with the IDRS pending transaction. The pending Master File posting cycle on the IDRS "PN" status transaction extends to account for any Posting Delay Code impact on the transaction.

# General EPMF Entity and EPMF EFAST/EFAST2 Unpostable Codes Information and Resolution

3.12.166.19 (07-01-2021) General EPMF Entity and EPMF EFAST/EFAST2 Unpostable Codes Information and Resolution This section contains procedures used to correct General EPMF Entity Unpostable Codes and ERISA Filing Acceptance System (EFAST/EFAST2) unpostables.

# General EPMF Entity Unpostable Code Information and Resolution

3.12.166.19.1 (07-25-2024) General EPMF Entity Unpostable Code Information and Resolution The EPMF unpostables uses numbers 801 through 899. This section provides: The number and title of the unpostable, The unpostable condition (why the unpostable was created) The procedures for resolving the unpostable EPMF Entity records can be identified by File Location Code (FLC) 29. DON'T make changes to plan name, sponsor name, or administrator from a prior-year return if a more current return posted for the plan. Notify filer of changes made to the sponsor name, EIN, plan name and plan number, using Letter 1072C if applicable. If there are multiple unpostables letter for each year doesn't need to be sent. One letter for each EIN/plan number is sufficient. If inputting transactions to change the Master File that must post before the unpostable return posts, cycle the unpostable as needed. If closing an unpostable for both a TC 150 and TC 460 for the same module, cycle delay the TC 150 2 cycles to ensure the extension posts first. If CC UPRES displays the message "Other cases with the same TIN on CC UPTIN" , research CC UPTIN for open unpostables cases to determine if the corrected TIN has more unpostables that can be closed at the same time. If CC UPTIN research reflects other open unpostables, contact the employee assigned the case. If the case is assigned to another employee within the unit, request the case be reassigned, in order to close all cases involved. The employee with the oldest case should process the case. CC UPTIN updates daily, so GUF may reflect a case closed while IDRS indicates that it's still open. A Form 4251 charge-out generates for Entity unpostables. The clerical function forwards the Form 4251 to Files for Form 5500-EZ, Form 5558 (paper filed) and Form 8868 (paper filed) and requests the return. While CC ERTVU provides extensive return information captured from the return record, examine the return carefully to ensure correct transcription. The EFAST2 website can't be used to research return information for campus-processed unpostables. When working an unpostable case, always check for transcription errors first (compare the information on CC UPDIS with the information on the document). Correcting transcription errors may resolve the unpostable condition. If a return has "Prepared by TE/GE" , "Substitute Return" , "SFR" , or "Delinquent Return" , written on it, CCC "C" must be edited on it. If missing, edit it in the top margin of the return and add with URC 8. If a Form 3198-A is attached to the "secured" return that has instructions to allow Reasonable Cause (or statement to waive penalties), CCC "R" should also be present. If missing, edit CCC "R" on the return and add CCC "R" with URC 6. Never correct the plan number on Forms 5500–EZ to any number greater than 500. When working unpostables, completely review the case and resolve conditions that may result in a repeat unpostable. Programming problems occasionally make short-term changes necessary. If an unpostable cannot be corrected and closed by normal methods, close the unpostable using a URC 8. Using Form 13071 instructs Rejects on the correction needed. Example: CCC field can't have additional characters added to it, so URC 6 can't be used to correct it. Close using URC 8 and instruct Rejects how to correct it.

# EPMF EFAST and EFAST2 Unpostables

3.12.166.19.2 (07-01-2021) EPMF EFAST and EFAST2 Unpostables This section contains procedures used to correct ERISA Filing Acceptance System (EFAST) and EFAST2 unpostables. The EFAST and EFAST2 records can be identified by the following file location codes: FLC 56 or 84 – Paper returns processed through EFAST FLC 62 or 86 – Electronic returns processed through EFAST FLC 72 or 91 – Consolidated hand-print amended returns processed through EFAST FLC 92 or 93 – Electronic Forms 5500, 5500-EZ or 5500–SF returns processed through EFAST2 Note: OSPC records can be identified by the file location code FLC 29, or FLC 60 or 78 for foreign entities. Verify that the DLN matches when resolving an UPC 851. The EP Master File sends to GUF any EFAST or EFAST2 transaction that can't post. The EP Master File maintains the original EFAST or EFAST2 transaction on a recirculating file and releases the transaction after correcting the unpostable. EFAST/EFAST2 postings updates the entity with the information provided by the filer. EFAST/EFAST2 doesn't alter the return information received. EFAST/EFAST2 returns can't be re-processed through GMF. They must be corrected in GUF and returned to Master File, through GMF15. There will be Form 4251 charge-outs generated for EFAST unpostables. The return won't be attached to the Form 4251, because the return isn't available at the campus. The use of CC ERTVU provides extensive return information captured from the return record. Use the EFAST2 website to research, view and print Form 5500 filings. EFAST/EFAST2 processed returns aren't available in hard copy. IDRS CC ERTVU must be used to view these returns. Use the EFAST2 website to research, view and print Form 5500 filings. Use extreme caution when using URC D to correct EFAST/EFAST2 TC 150 Unpostables In the resolution of all EFAST/EFAST2 unpostable codes, there's an option to correct the case with URC D. However, use extreme caution when using URC D for resolving TC 150 unpostables; "801" , "808" , "823" , "869" and "877" . URC "D" deletes the transaction from processing with no further action and doesn't create an IDRS control base. The unpostable will go back to Master File and EPMF deletes the record from the recirculating file. Note: If resolving an unpostable that was erroneously closed with URC D, resurrect the deleted record by using CC ERTVU definer "Z" . When correcting a TC 150 unpostable, use a URC D, only with management approval, as a last resort after every other possible effort has been made to correct the unpostable condition. EFAST2 allows multiple submissions of a return to correct erroneous data. If multiple submissions of the same return unpost on the same day, they all unpost under the same unpostable code e.g., 801, 803, 823. If there are multiple unpostable filings for the same EIN, plan number, and tax period all submitted on the same day (use the Julian date of the DLN to determine submission date), treat the first submission as the TC 150, and treat the other submissions as amended filings. Close the TC 150 first and close the duplicate submissions using URC 6 to add CCC "G" . Cycle delay the posting of the duplicate submissions to post after the TC 150 posts.

# Employer Identification Number (EIN) Corrections

3.12.166.20 (07-01-2021) Employer Identification Number (EIN) Corrections This section contains procedures to use when a corrected EIN is different from the EIN provided on the return. Perform all necessary research to determine the correct EIN using CCs NAMEE and NAMEB. If the corrected EIN is different from what the filer provided on the return, correspond using Letter 1072C to notify the filer of their correct EIN using the most current address on the filer's module. Letter 1072C doesn't need to be sent for the following: EIN is missing digits, transposed digits, or only one digit is incorrect excluding transposed digits. EIN merged with another number. EIN was recently established (TC 000) or Letter 1072C was previously issued.

# Entity UPC 801 – EIN Not Established on Master File

3.12.166.21 (07-01-2021) Entity UPC 801 – EIN Not Established on Master File Unpostable Condition – The EIN on a transaction code (TC) other than a TC 000 (Document Code 04 or 63) doesn't match an EIN on the EPMF. Resolution: If IDRS research locates a different EIN for the filer, make sure to verify the change in sponsor before inputting (URC 6) to the EIN located. For information pertaining to change in sponsor, see IRM 3.12.166.8.2 or IRM 3.12.166.21.3 (2)"IF/THEN" chart. Notify the filer using the applicable letter. Note: Research the reported EIN/plan number, Gov EIN/plan number and previous sponsor to determine the appropriate place to post the return. If during resolution the EINs are consolidate (TC 011), a notice CP 212 generates notifying the filer of the correct EIN to use. When changing an EIN or plan number, check the new module for a posted TC 150. This helps avoid repeat unpostables (UPC 808). If a TC 000 is needed to establish an account, don't establish it with a trust EIN. Exception: The trust EIN may be used to file a Form 5500–EZ (or Form 5500-SF filed in lieu of a Form 5500–EZ) only if the employer has no other EIN on the BMF or EPMF. If after researching IDRS, you determine the filer is filing using their trust EIN because they aren't required to have an EIN for their business, don't assign another EIN. Ensure that the EIN is truly the Plan's trust EIN and not the EIN of the bank or other entity. Note: As of January 2021 the Form 5500-SF can no longer be filed in lieu of a Form 5500-EZ. If inputting a TC 000 to establish an account, a TC 000 may also be necessary to establish the plan number. Establish the EPMF first, then establish the plan using CC EPLANR and cycle delay 1.

# Entity UPC 801 – EIN Mismatch

3.12.166.21.1 (07-01-2021) Entity UPC 801 – EIN Mismatch Unpostable Condition – A transaction other than a TC 000 (Document Code 04 or 63) attempts to post and fails to match an EIN of an account on the EPMF. TC 121, 122, 123 or 125 generates to Entity in all seven campuses that handle EACS/EDS transactions from the Ohio AO. Resolution RC 1 – Void the document with URC 2 back to the originator.

# EFAST UPC 801 – EIN Mismatch

3.12.166.21.2 (07-01-2021) EFAST UPC 801 – EIN Mismatch Unpostable Condition – An EFAST TC 150 with CCC "G" (amended return) attempts to post and the EIN on the transaction doesn't match an EIN on the EPMF. Resolution for TC's other than 150 and 154: Close the unpostable with URC D. Note: Never Delete a TC 150. Resolution for TC 150 – Research the unpostable EIN using research instructions (e.g., CCs INOLE, ERTVU, NAMEE, EMFOL etc.). See IRM 3.12.166.12, Research Information, Methods and Tools, for additional research information. If Then The EIN was established on the EPMF Close the unpostable with URC 0 to post with no change. Someone previously resolved the return with URC D erroneously Input a TC 590 to satisfy the module. Bring back the deleted record by using CC ERTVU definer "Z" . Close the unpostable with URC 0 to post the return as an amended. Note: When correcting a TC 150 unpostable, use a URC D only with management approval, as a last resort after making every other possible effort to correct the unpostable condition. The account for the transaction is found under another EIN, plan number and/or plan year ending Close the unpostable with URC 6 to correct the EIN, plan number and/or plan year ending. The account for the transaction isn't found and there's sufficient information available to ESIGN an EIN ESIGN an EIN using CC ERTVU information and/or information found on the EFAST2 website. Close the unpostable with URC 6 to correct the EIN and establish plan. The account for the transaction isn't found and sufficient information isn't available to ESIGN an EIN Close the unpostable with URC D to delete the transaction with no further action. This doesn't create an IDRS control base. The unpostable goes back to Master File so EPMF can delete it from the recirculating file.

# EFAST UPC 801 – EIN Not Established TC 150

3.12.166.21.3 (08-29-2024) EFAST UPC 801 – EIN Not Established TC 150 Unpostable Condition – The EIN on a transaction other than a TC000 doesn't match an EIN on the EPMF. Resolution – Research the unpostable using CCs INOLE, INOLEG, NAMEE, EMFOL, ERTVU, and the EFAST2 website to determine the appropriate resolution. Note: Research the reported EIN/plan number, Gov EIN/plan number and previous sponsor to determine the appropriate place to post the return. If Then The EIN is established on the BMF Close the unpostable with URC 0 and a 2 cycle delay. This will allow the system to establish the plan first (using the information from CC ERTVU) and then post the TC 150. The EIN isn't established and research determines the TIN is an SSN Research CC NAMEE/NAMEB for an EIN for the sponsor. If found, close the unpostable with URC 6 to the correct EIN. Send letter 1072C informing the filer they used their SSN in error and to use the correct EIN on future filings. If not found, ESIGN an EIN using CC ERTVU information and/or information found on the EFAST2 website. Close the unpostable with URC 6 to the newly assigned EIN (cycle delay as appropriate). Send letter 1072C informing the filer they used their SSN in error and to use the newly assigned EIN on future filings. The EIN isn't established and research determines the TIN isn't an SSN Research CC NAMEE/NAMEB for an EIN for the sponsor. If found, close the unpostable with URC 6 to the correct EIN and send letter 1072C to notify the filer of the correct EIN to use when filing future returns. If not found, ESIGN an EIN using CC ERTVU information and/or information found on the EFAST2 website. Close the unpostable with URC 6 to the newly assigned EIN (cycle delay as appropriate). Send letter 1072C informing the filer to use the newly assigned EIN on future filings. The EIN found is different Close the unpostable with URC 6 to correct the EIN. Send letter 1072C to notify the filer of the correct EIN to use when filing future returns. The EIN reflects a business trust and no other EIN can be found ESIGN an EIN using CC ERTVU information and/or information found on the EFAST2 website. Close the unpostable with URC 6 to correct the EIN and establish plan. Let the notice generate notifying the filer of their EIN. The TC 150 is for a one participant plan, established as a trust Research for another EIN. If not found, Close the unpostable with URC 0 to establish the plan. If found, close the unpostable with URC 6 to correct the EIN, make sure the name controls match. Send letter 1072C to notify the filer of the correct EIN to use when filing future returns. More than one EIN is found for the sponsor Determine which EIN is correct. Close the unpostable with URC 6 to the correct EIN. Input a TC 011 from the incorrect EIN to the correct EIN. See IRM 3.13.36.22 for consolidating EIN's. Note: Follow local routing procedures when merges or consolidations are needed. The EIN isn't found ESIGN an EIN using CC ERTVU information and/or information found on the EFAST2 website. Close the unpostable with URC 6 to correct the EIN and establish plan. Let the notice generate notifying the filer of their EIN. CC ERTVU information shows an incomplete address, Don't correct or delete the incomplete address. Close the unpostable with URC 0 to post the return as filed. A personal representative on a deceased filer's plan files the return Contact the personal representative via correspondence using Letter 1072C instructing them to terminate the plan, amend and final the return and roll the assets over into a new plan. The filer will need to create a new plan with a new plan name. Input a URC 0 to post the return. CC ERTVU is blank and shows no data Close the unpostable with URC D. The Filing Requirements for a Plan changes due to a Takeover or Sale Close the unpostable with URC 0 to post the return and input a TC 591 cc 097 on the old sponsor when there's a change of this nature. See IRM 3.12.166.8.2, Filing Requirements for Plan Changes Due to Takeover or Sale, for more information. Note: The input of URC 0 and 6 establishes the plan information from CC ERTVU when correcting an unpostable with no plan established. A TC 013, 014, or 016 may need to be input to perfect the entity when there's filer impact.

# EFAST UPC 801 – EFAST Generated TC 151

3.12.166.21.4 (07-01-2021) EFAST UPC 801 – EFAST Generated TC 151 Unpostable Condition – A TC 151 attempts to post and the EIN on the transaction doesn't match the EIN on the EPMF. Resolution – Research the unpostable using CC EMFOL and ERTVU to determine the appropriate resolution. If no TC 150 is present, URC D to delete the transaction and close the unpostable. Note: Programming was implemented to drop any UPC 801 TC 151 from EFAST at Master File and WON'T unpost.

Beginning January 1, 2025, Form 5558, Application for Extension of Time to File Certain Employee Plan Returns, can be electronically filed through EFAST2. The DLN will start with 92 and have a doc code of 55. A Form 4251, Return Charge-Out, is the only information that will be received regarding the unpostable. The Form 5558 can't be viewed on the DOL EFAST2 site. Due to the lack of information available with an electronically filed Form 5558, all UPC 801 TC 460 unpostables should be closed with URC D.

# Entity UPC 801 – TC 460 Form 5558 Extension (paper filed)

3.12.166.21.6 (06-13-2025) Entity UPC 801 – TC 460 Form 5558 Extension (paper filed) Unpostable Condition – A TC 460 attempts to post and the EIN on the transaction fails to match an EIN of an account on the EPMF. Resolution – Research IDRS for another EIN. If the Form 5558 isn't received with the Form 4251, order the document from Files using CC UPCASD. Never submit a D4 document request for a Form 5558. If the document isn't received after three attempts, close the unpostable with URC D (if unable to determine how to close following the instructions below). If And Then Another EIN is found on the EPMF The plan name/number on the Form 5558 is established Note: If there's only one plan number established and it doesn't match what's on the Form 5558 but the plan name matches, close the unpostable to the established plan number regardless of what's on the Form 5558. Close the unpostable with URC 6 to correct the EIN, plan number and name control (if needed). Edit the Form 5558 with the correct EIN, plan number and name control (if needed). Another EIN is found on the EPMF The plan name/number on the Form 5558 isn't established Establish the plan name/number provided on the Form 5558. Note: If there's no plan number use 001 (or the next available plan number in the series). Close the unpostable with URC 6 to the correct EIN, plan number and name control (if needed) with the appropriate cycle delay.

Resolution – Re-assign the unpostable to EP Accounts Unit number 0437500001. See IRM 3.12.32.18.1, Command Code UPASG-Screen Formats, for instructions on how to re-assign the unpostable.

# Entity UPC 802 – TC 000 Account Already Established

3.12.166.22 (07-01-2021) Entity UPC 802 – TC 000 Account Already Established Unpostable Condition – A TC 000 (Doc Code 04 or 63) attempts to establish an EPMF account but the account is already on EPMF. Resolution – Void the unpostable with URC D.

# Entity UPC 803 – Name Control Mismatch

3.12.166.23 (07-01-2021) Entity UPC 803 – Name Control Mismatch Unpostable Condition – An input transaction matches an EIN on the EPMF but doesn't match the name control or other proximal checks. Resolution RC 1: If the Master File name control is incorrect, and it's determined the name control on the unpostable document is correct, input a name change using CC BNCHG. Close the unpostable with URC 0 and a cycle delay to post after the TC 013.

# Resolution When The Wrong EIN Was Used

3.12.166.23.1 (07-01-2021) Resolution When The Wrong EIN Was Used If you can't resolve a TC 150, TC 154 or TC 460/620 and the name control problem using the procedures in the previous section, or the wrong EIN appears to be used, follow procedures for UPC 801. If the Form 4251 is received from Files showing a different EIN/Name Control, correct the unpostable with URC 6. If the unpostable is a TC 121, 123 or 125, research CC PLINF definer E. If the entities on CC PLINF and CC ENMOD are the case, correct the unpostable with URC A. Note: CC PLINF is the Employee Plan/Exempt Organization Application Control System (EACS). This system is used to control various application forms for Employee Plans and Exempt Organizations. The Plan Case Control File (PCCF) contains the complete information required to control the applications: plan characteristics, entity information such as name and address, controlling information such as status and specialist assignment, and final disposition of the application.

# Resolution When Another EIN is Found

3.12.166.23.2 (07-01-2021) Resolution When Another EIN is Found If research locates another EIN, determine on which file the EIN is located. If the Master File indicator is for the EPMF, correct the unpostable with URC 6. If the Master File indicator is for the BMF, use CC ENMOD or INOLE to compare the BMF entity with the EPMF entity. If the entities are the same, input TC 000 (CC BNCHG) to establish the entity on the EPMF. Correct the unpostable with URC 6. If the Master File indicator isn't EPMF or BMF, use CC ENMOD and compare the entity on ENMOD with the entity on PLINF. If the entities are the same, input TC 000 to establish the entity on the EPMF. Correct the unpostable with URC 6.

# Resolution for TC 125

3.12.166.23.3 (07-01-2021) Resolution for TC 125 If the TC is a 125 and the entities aren't the same on CC ENMOD and PLINF: Void the unpostable with URC 2. Forward the unpostable document to the Ohio Area Office. Explain that the name on the document doesn't agree with the name on the EPMF for that EIN. Also notify them that the document hasn't posted to the EPMF. If an entity change (Document Code 63 or 64), correct the name control if it can be resolved from the optional field displayed on UPDIS. Otherwise, void the unpostable with URC 2, back to originator.

# Resolution for TC 59X, 560, 460/620, 474, 475 or 930

3.12.166.23.4 (07-01-2021) Resolution for TC 59X, 560, 460/620, 474, 475 or 930 If a TC 59X, 560, 460/620, 474, 475 or 930, correct the name control if it can be resolved from the optional field displayed on UPDIS.

# EFAST UPC 803 Name Control Mismatch

3.12.166.23.6 (06-13-2025) EFAST UPC 803 Name Control Mismatch Unpostable Condition – When an EFAST/EFAST2 transaction failed to match either: Three out of four positions (using the proximal method) of the entity name control The old name control Three out of four of the left-most non-blank positions (proximal) of the entity sort name line The four left-most significant characters of the first three words of the entity primary name line and then the sort name line Resolution RC 2 – If the transaction contains evidence of a name change or the established name line was misspelled: Note: The vendor sends the return information to the EPMF as received. Therefore, use the first four characters of the name line regardless of whether it's a trust, estate, personal name or business. IRS accepts the name control as received. Note: When resolving a name control issue, be sure to check the new module for a posted TC 150. This helps avoid repeat unpostables (UPC 808). If Then A TC 013 is pending Close the unpostable with URC 0 and cycle to post after the TC 013, if necessary. An EIN is found and the name control is different Ensure the name control is correct by inputting a TC 013 to correct the name. Close the unpostable with URC 6 to correct the name control and cycle delay 2 to post after the TC 013. The name control on the unpostable document is incorrect because of filer error in submission (e.g., misspelling, ampersand missing or spelled out) Close the unpostable with URC 6 to correct the name control. Input a TC 013 to correct the name line and cycle delay 2 to post after the 150, as the posting of the return will update the name line to the incorrect filing.

Resolution – Research the unpostable to determine if the return is an amended or duplicate return. See IRM 3.12.166.12, Research Information, Methods and Tools, for additional research information. Verifying the Plan Characteristic Codes located on Lines 8a and 8b of the Form 5500 may help to identify if the return is an amended or a true duplicate. Refer to IRM 3.12.166.16.1 (8) for information on the Plan Characteristic Codes. If Then It's determined the unposted TC 150 belongs on the module it attempted to post to, and an unreversed TC 150 is already on the EPMF, and the unposted TC 150 appears to be a duplicate Close the unpostable with URC 0 to post with no change. The Master File converts the transaction to TC 976. It's determined the unposted TC 150 belongs on the module it attempted to post to, and an unreversed TC 150 is already on the EPMF, and the unposted TC 150 appears to be amending the posted filing Add CCC "G" and close the unpostable with URC 6 to correct the CCC. If the return is a Form 5500-EZ, also edit the "G" code on the document. The posted TC 150 is an EFAST/EFAST2 processed return, and the posted return appears to be posted to the wrong EIN, plan number, and/or plan year ending Input a TC 151 to move the posted return to the correct module, then close the unpostable with URC 0 to post the TC 150 with no change.

The correct account is found under another EIN, plan number and/or plan year ending Close the unpostable with URC 6 to correct the EIN, plan number and/or plan year ending. If a TC 420 is present on EMFOLT on the incorrect EIN, contact the Baltimore Area Office Coordinator at 410–962–9403 to close the account on AIMS (TC 421) before correcting the unpostable. The posted TC 150 is an IRS processed return, the unpostable TC 150 is an EFAST/EFAST2 document, and both TC 150s belong to the same tax module Add CCC G to the EFAST/EFAST2 TC 150 and close the unpostable with URC 6 to post as an amended return. The posted TC 150 is an IRS processed return, the unpostable TC 150 is an EFAST/EFAST2 document and the data on the returns are identical (duplicate) Close the unpostable with URC 0 to force the EFAST/EFAST2 return to post as TC 976 (duplicate). The TC 150 is for an unestablished plan number Close the unpostable with URC 6 to the new plan number and Master File generates the TC 000 and post the return to the new plan number. It's determined the TC 150 is a new plan and not a duplicate through verification of Form 5500 Line 8 and the List of Plan Characteristics Codes for Lines 8a and 8b Pension Codes Establish a new plan using the information on the EFAST2 website and CC ERTVU. Close the unpostable with URC 6 to post after the new plan establishes. It can't be determined where the TC 150 should post Close the unpostable with URC D to delete the transaction with no further action. This doesn't create an IDRS control base and the unpostable goes back to Master File so EPMF can delete it from the recirculating file. An amended return is received and there's no TC 150 (original posting) Close the unpostable with URC 0 to post the return.

Note: Form 8868 extension (TC 460/620) unpostables are worked/resolved the same way as Form 5558 (TC 460/620) unpostables. The only difference is the form the extension request is being filed on. Beginning January 1, 2025, the Form 5558 can be electronically filed through EFAST2; however, EFAST2 is unable to accept payments. Since payments can be made with a Form 5330 extension request, the Form 5330 section on the Form 5558 needed to be moved to a form that can be filed with payments. Therefore, the entire Form 5330 section was removed from the Form 5558 and added to the Form 8868. The extension request is processed the same.
