You expected a refund. You got a letter saying it was applied to a debt. Before you call anyone, pull the transcripts for the refund year and every year with a balance. The offset will be on both, as a matched pair.
The legal authority
IRC 6402(a) says that for any overpayment, the IRS "may credit the amount of such overpayment, including any interest allowed thereon, against any liability in respect of an internal revenue tax on the part of the person who made the overpayment" and "shall, subject to subsections (c), (d), (e), and (f), refund any balance."
Subsections (c) through (f) require reductions for past-due child support, debts owed to federal agencies, past-due state income tax obligations and covered unemployment compensation debts. The statute sets priorities among them. Child support certified by a state comes first under subsection (c). Federal agency debts under subsection (d) come before state income tax and unemployment debts under subsections (e) and (f), and all of those come before an overpayment is credited to future estimated tax under subsection (b).
Offsets to your other tax years: TC 826 and TC 706
When the overpayment goes to another IRS balance, two lines post.
On the overpaid year: TC 826, which Document 6209 defines as "an ECC computer generated debit for the amount of overpayment credit transferred to another tax module within this taxpayer's account. The corresponding credit is 706."
On the year that owed: TC 706, "Generated Overpayment Applied from Another Tax Module," which 6209 says is "an ECC computer generated transaction in the amount of a credit offset into a Tax Module. A TC 826 debit transaction is the corresponding entry." The same entry explains the logic: "Before generating a refund, the computer analyzes all Tax Modules in the account and offsets the credit to any Tax Module with a balance past due."
| Year | Code | Explanation | Amount |
|---|---|---|---|
| 2024 | TC 826 | Overpayment transferred to another year | 1,800.00 |
| 2021 | TC 706 | Overpayment applied from another year | -1,800.00 |
Same amount, opposite signs, two different years. If you can match every TC 826 to a TC 706, you have traced the money.
Document 6209 also lists the reversal codes. TC 821 reverses a generated TC 826 on the overpaid year, with TC 701 as the corresponding debit on the receiving year. If an offset was applied to a year that was later abated, those are the lines that move it back.
Offsets between business and individual accounts
The IRS can also move individual overpayments to business balances in some cases. Document 6209 describes TC 796 on the business side as a credit for an individual overpayment transferred to the business master file, generated when a taxpayer overpays the individual account by $100 or more and underpays a business account, with exclusions for certain entity types. The individual side shows a TC 896, which 6209 says reflects offsets to certain other accounts and from the individual master file to the business master file. If you are a sole proprietor with payroll tax debt, your personal refund may land on the business account.
Offsets to other agencies: TC 898
When the refund goes to a non-IRS debt, it posts as TC 898. Document 6209 titles it "BFS TOP Offset" and says it is a "Treasury Offset Program (TOP) offset initiated by FMS." It "posts with the trans date and DLN of the refund from which it originated," carries a memo amount, an offset trace number and a cross-reference SSN, and "reduces the amount of the refund with which it is associated."
That means the TC 898 sits next to the TC 846. The refund was issued, and part or all of it was diverted to the other agency. The offset trace number is the key to any later reversal.
IRC 6402(g) limits where you can fight an offset to another agency's debt. It says no federal court has jurisdiction to restrain or review a reduction under subsections (c) through (f), and such a reduction is not subject to review by the IRS in an administrative proceeding. The statute preserves actions against the federal agency or state that received the money. So if the underlying debt is wrong, your dispute is with that agency, not the IRS.
Reversals of agency offsets: TC 899 and TC 766
Document 6209 defines TC 899 as "FMS TOP Offset reversal or Agency Refund/Reversal" that "reverses a prior posted TC 898 with the same OTN." It lists four types: an FMS TOP offset reversal, an agency refund of a TOP offset, an FMS refund of a TOP offset, and an agency refund reversal.
A TC 766 with an offset trace number can also reverse a TC 898. That is the dual meaning of TC 766 covered in TC 766 and TC 768. If you see a TC 766 that matches an earlier TC 898, the offset was reversed and the money came back to the IRS account, where it may refund or offset again.
Joint returns and the injured spouse
Offsets on joint returns raise a fairness problem. If one spouse owes the debt and the other contributed to the overpayment, the non-liable spouse can ask for their share. The IRS instructions for Form 8379, Injured Spouse Allocation, describe it as filed by one spouse on a jointly filed return when the joint overpayment was, or is expected to be, applied to a past-due obligation of the other spouse.
Document 6209 lists TC 971 action code 071, "DMF-Injured Spouse Claims," and TC 897, "DMF Offset Reversal," which credits the module with a debt management offset reversal. IRC 6402(d)(3)(B) also requires specific notice and procedures when a federal Social Security overpayment debt is offset from a joint refund. The firm's main site has a guide to injured spouse relief.
Injured spouse is not innocent spouse. Injured spouse is about a refund taken for the other spouse's separate debt. Innocent spouse is about liability for tax on the joint return itself. They use different forms and different rules.
Bypassing the offset
There is one more code worth knowing. Document 6209 lists TC 971 action code 036, "IRS Offset Bypass Refund." It marks a refund issued without offsetting to other tax debts. If you are facing a genuine hardship and the refund is being offset to an old tax year, it is worth asking whether an offset bypass refund is available before the offset posts.
You are entitled to notice
The statute requires the IRS to tell you when an offset to another agency happens. IRC 6402(d)(1)(C) requires notice to the person that the overpayment has been reduced to satisfy a federal agency debt, and subsections (e)(1)(C) and (f)(1)(C) contain parallel notice requirements for state income tax and unemployment compensation debts. Keep those notices. They identify the agency, which is who you deal with if the debt is wrong.
For offsets to your own other tax years, the transcript itself is the record, and the TC 706 on the receiving year shows where the money landed.
Tracing checklist
- On the refund year, list every
TC 826,TC 896andTC 898. - On every other year, find the matching
TC 706or business-sideTC 796. - For each
TC 898, note the date and amount, then look for aTC 899or a matchingTC 766. - Check for reversals:
TC 821andTC 701. - If the refund was joint and the debt was one spouse's, consider an injured spouse claim.
One more practical point: an offset to an IRS balance reduces that balance as of the offset. If you are on an installment agreement or negotiating one, ask the IRS to confirm the new balance after the TC 706 posts so your payment figures are based on current numbers.
If an offset landed on a year that is in currently not collectible status, the CNC status does not stop it; see TC 530.
Offsets feel like the IRS took your money. Usually it applied your money to a debt. The transcript tells you which debt, and whether the IRS's version of that debt is right.
