Earned Income Tax Credit (EITC) and Other Projects
21.5.10.4.1 (10-01-2014) Earned Income Tax Credit (EITC) and Other Projects Taxpayers who claim Earned Income Tax Credit (EITC) for a current or prior tax year may experience a delay in receipt of the EITC and/or the Additional Child Tax Credit (ACTC) portion(s) of their refunds because of a screening process which identifies questionable item(s) on their return. Caution: Do not release the refund under any circumstance, only Campus Exam has this authority. The taxpayer receives a Computer Paragraph CP 75, Refund Hold - Return Being Examined Regarding Credits Claimed, Need More Information, CP 75A, Refund Hold - Return Being Examined Regarding Credits, Dependent Exemption(s) and/or Filing Status, Need More Information, CP 06, Request for Supporting Documentation, or CP 06A, Request for Supporting Documentation. The CP 75 and CP 06 notices (which generates within 17 days from the date the credit is frozen) advise the taxpayer that the refund is on hold pending the examination of the tax return. The notices advise the taxpayer of the issues being examined. Another letter is issued within 30 days requesting the same information, if the taxpayer does not reply. The subsequent letter includes a report that proposes changes to the taxpayer's account. For more information refer to IRM 4.19.14.5, RPS Casework Procedures.
Referring Cases to the Taxpayer Advocate Service (TAS)
21.5.10.4.1.1 (10-01-2015) Referring Cases to the Taxpayer Advocate Service (TAS) Refer taxpayers to TAS when the contact meets TAS Criteria and you can't resolve the taxpayer's issue the same day. See IRM 13.1.7.3, TAS Case Criteria, for more information. "Same Day" cases include cases you can completely resolve in 24 hours, as well as cases in which you have taken steps within 24 hours to begin resolving the taxpayer's issue. Do not refer "same day" cases to TAS unless the taxpayer asks for a referral to TAS and the case meets TAS criteria. Refer to IRM 13.1.7.5, Same Day Resolution by Operations. Complete Form 911/e-911, Request for Taxpayer Advocate Service Assistance (and Application for Taxpayer Assistance Order), and route the form to TAS.

Compliance Refund Hold Projects
21.5.10.4.1.2 (10-03-2022) Compliance Refund Hold Projects A Transaction Code (TC) 810 or TC 570 indicates a stopped/frozen refund. TC 810 or TC 570 is used by Exam or Automated Questionable Credit (AQC) if a taxpayer's return is under review or the previous review is not closed. If the taxpayer does not claim the same items on a subsequent return, the refund is released in most cases. Consider a referral to Taxpayer Advocate Services in instances where the taxpayer indicates there is an economic hardship. Note: Use Audit Information Management System (AIMS) status codes to determine how to respond to the taxpayer for Exam related issues. The taxpayer has the right to finality, which is the right to be informed of the status of his or her examination and be given a clear explanation of what is expected of them or what the taxpayer may expect from IRS (including time frames). Research AIMS on the tax period that is frozen. Refer to Exhibit 21.5.10-1, Audit Information Management System (AIMS) STATUS CODE GUIDE - FIELD CASES, and Exhibit 21.5.10-2, Audit Information Management System (AIMS) STATUS CODE GUIDE - CAMPUS CASES, for more information on AIMS status codes.

Note: The ACTC is only held in conjunction with the EITC audit issues. If Command Code (CC) TXMOD shows a TC 570 or TC 810 with open AIMS information, follow procedures below for Exam related issues: Note: If no AIMS information and there is a TC 810 with a TC 971 Action Code (AC) 128 and a MISC field of AQCPTC###, refer the taxpayer to the Automated Questionable Credit toll-free line 855-873-2100 and provide the hours of operation, Monday - Friday 7:00 am - 9:00 p.m. CT.

Audit Reconsiderations
21.5.10.4.3 (10-02-2023) Audit Reconsiderations Individual Master File (IMF) Audit Reconsideration is the process the IRS uses to reevaluate the results of a prior audit where additional tax was assessed and remains unpaid, or a tax credit was reversed. Examination cases closed as Non-Examined with no additional tax assessed do not meet the definition and criteria of an Audit Reconsideration. Do not route to Exam. Refer to IRM 4.13.1.3.1, Research/Initial Case Screening, for information to determine if the case meets audit reconsideration criteria. Refer to IRM 4.13.1.3.2, Function Responsible & Routing Instructions, for routing instructions. Taxpayers requesting audit reconsideration typically have a balance due and may require holds on collection action. If the taxpayer is inquiring about the status of their reconsideration request, refer to IRM 4.13.1.3.3, Role of Contact Employees when a Reconsideration Request is Received and the Examination was Performed in the Area Office or Campus Examination Function. Note: See Document 6209, Section 12.5(8), Disposal Codes. Business Master File (BMF) Audit Reconsideration - BMF Audit Reconsiderations go through Exam Classification.

Note: An adjustment to an account with a previously posted TC 160 requires a secondary TC 16X to prevent an Unpostable 334 Reason Code (RC) 6 situation. If Exam Classification returns the BMF Audit Reconsideration and provides instructions to disallow the claim, follow procedures in IRM 21.5.3.4.6.1, Disallowance and Partial Disallowance Procedures.
