Identity Theft Returns
25.25.4.2 (08-13-2025) Identity Theft Returns Identity theft (IDT) occurs when a return is filed by someone who is not the true taxpayer without the Taxpayer Identification Number (TIN) owner's knowledge/consent. An IDT determination has been made by RIVO when the account contains an unreversed transaction code (TC) 971 action code (AC) 506 with one of the following MISC fields: WI PRP OTHER1 WI IVO RFND WI PRP DDB WI AM OTHER WI AM TAP OMM WI IVO OMM WI IVO OMMGB Note: Operation Mass Mailing (OMM) miscellaneous notes are no longer used, however they may appear on older accounts Taxpayers may notify the IRS if they are a victim or potential victim of IDT. The following are some ways to determine an IDT filing has occurred: RIVO IDT markers in paragraph (2) above. Internal referrals from other areas, such as Compliance, who have made an IDT determination through their research. Special agent information is received. Duplicate filing condition (-A Freeze) is present on the account, indicating two returns have been filed for the same TIN and tax period. Often, one return is filed by the true taxpayer and one by someone using the true taxpayers information without permission. Signed Form 14039, Identity Theft Affidavit, or other signed correspondence, submitted by the taxpayer, stating they have been a victim of identity theft.
Identity Theft Return Categories
25.25.4.3 (08-13-2025) Identity Theft Return Categories Potential IDT returns are separated by categories in EFDS for the purpose of identifying, referring, or adjusting Master File (MF) accounts for RIVO. The category determines the inventory type in EFDS. ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡"≡ ≡ ≡ ≡ ≡ ≡ ≡" ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡"≡ ≡" ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡
Identity Theft Category 7 — Single Return/Deceased/X-REF - No Lost Refund Process
25.25.4.4 (08-13-2025) Identity Theft Category 7 — Single Return/Deceased/X-REF - No Lost Refund Process An IDT return posted, the refund was stopped, and the true taxpayer did not file a return or filed jointly under a cross-reference (X-REF) TIN. Check Integrated Data Retrieval System (IDRS) and Account Management Services (AMS) to review the account information and determine if the case involves a single return, deceased taxpayer or X-REF TIN joint filing issue. Note: When resolving an IDT case manually, include the correct actions to resolve the account if the issues below are present: If the IDT return filing status is Married Filing Jointly (MFJ) or Married Filing Separate (MFS) and the spousal name listed is not the spouse of the primary taxpayer, correct the filing status and name line on the primary TIN to remove the spousal information. Follow the IDT instructions below as applicable on the spousal TIN to input the IDT marker, correct the address and send Letter 4674C, IRS Identified ID Theft Post-Adjustment Letter, as appropriate. Note: Cases closed in mass using the IAT ID Theft Tool will not be sent a Letter 4674C. If the IDT return filing status is MFJ or MFS and the spousal name listed is the spouse of the primary taxpayer, follow the instructions below for input to the spousal account to input the IDT marker, correct the address and send Letter 4674C, IRS Identified ID Theft Post-Adjustment Letter, as appropriate. Note: For MFJ cases, issue one Letter 4674C to the joint name line. If in reviewing the account, it is identified that other tax periods with RIVO involvement are affected by IDT, then all affected active tax years must be resolved at the same time. Note: Active tax years are tax years with an open issue, such as a credit or debit balance. IF THEN 1 Single return or Deceased taxpayer with no X-REF SSN Reverse all offsets and credit transfers. For Treasury Offset Program (TOP) Offsets, see IRM 21.4.6.5.1.2.4, TOP Offset Reversals Involving ID Theft and ID Theft with Fraudulent Returns.

If not deceased, update CC ENMOD to the confirmed good address provided by the TIN owner. If no confirmed good address was provided, update the address to the Service Center Address. See IRM 25.23.2.3.7, When to Update the Victim's Address. Exception: If there is no current contact with the TIN owner and the year being resolved is an older (prior) year and the account contains non-IDT subsequent or current year filings, do not change the address to the Service Center Address, leave the address as it is on CC ENMOD.

Reversing Identity Theft Lost Refunds
25.25.4.6 (08-13-2025) Reversing Identity Theft Lost Refunds In cases where an IDT return was filed and the refund was lost, the refund needs to be moved off the good taxpayer's account. This must be done to ensure the account reflects only the good taxpayer's information. Use CC IDT48 and CC IDT58 to move refunds lost from the account. These CC's credit the TIN owner's account and move the refund to the General Ledger (GL) 1545 account. CC IDT48 is used to move an entire refund CC IDT58 is used to move the unrecoverable portion of a partially recovered refund Exception: If the lost refund is the result of an irreversible child support offset use CC CSO48 and CC CSO58. See IRM 2.4.61.8 , Command Code CSO48 - Request Formatted Input Screen, and IRM 2.4.61.9, Command Code CSO58 - Request Formatted Input Screen for additional information. Use CC CMODE to direct the request to the service center where the taxpayers refund originated. See IRM 2.4, IDRS Terminal Input, and IRM 2.4.61.1.6, Terms and Acronyms, for additional information. In certain circumstances, it may be necessary to reverse previous actions taken that debited the GL 1545 account with the posting of a TC 841 or TC 700 to the tax account (e.g., duplicate TC 841 or actual credit has been returned to the module, etc.). To reverse a TC 841 or TC 700 posted in error, see IRM 25.23.4.16, Form 3245/3809 Reversals.
