If the non-owner of the CN has a different valid TIN, this is a mixed entity (MXEN). When a refund should be issued, the tax year account must be moved to the correct TIN.
Any overpayment attributable to the non-owner of the CN that has been offset to a Bureau of Fiscal Services debt must be reversed using HC 4. If the overpayment is over one year old, move it to excess collections. A letter must also be sent to the taxpayer who has the FMS debt, notifying them of the reversal. If the BFS offset is over 6 years old, refer to IRM 21.4.6.5.1.2.4, TOP Offsets Involving ID Theft and ID Theft with Fraudulent Returns.
Reverse any IRS offsets attributable to the non-owner of the CN. If the overpayment is over one-year old, move the overpayment to excess collections. A letter should be sent to the CN owner informing them of the overpayment reversal when returning the offset to the originating module will result in a balance owed for the valid taxpayer. If the year the offset is being moved from is also impacted by identity theft, a closing letter for that tax year may be required to sufficiently describe actions taken to resolve the account. Reversal of the offset does not need to be addressed in more than one letter. Refer to IRM 25.23.4.18.1, General IDTVA Letter Procedures, for additional information.
If adjusting 2008 and FTHBC was claimed by the invalid taxpayer, see IRM 21.6.4.4.17.4, Manually Adjusting the Recapture Amount, to update the IMFOLF information.
