TC 767: Reversal of TC 766 (Plain or With an Offset Trace Number)

What the code actually does

Document 6209 defines the plain form of TC 767 as "a generated error correction which reverses a TC 766 credit allowance posted in error." TC 766 is the generic bucket code covering refundable credits verified across a wide range of return types; TC 767 is what takes one of those allowances back off the module. Doc 6209 traces it to "the appropriate line item adjustment of an Examination or DP Tax Adjustment" — an audit finding or a routine data-processing correction, not a taxpayer request.

That single sentence, though, only describes one of two transactions that share the numeral 767. The other exists specifically to correct a different kind of TC 766 — one that reversed a Treasury Offset Program (TOP) offset rather than allowing a new credit.

The dual meaning — plain TC 767 versus TC 767 with an OTN

A TC 766 itself carries a dual meaning: input on its own, it allows a refundable credit; input with an Offset Trace Number (OTN), it instead reverses a prior TC 898 Treasury Offset Program offset, returning money that had been intercepted for a debt like child support or a defaulted federal loan. TC 767 mirrors that same split one level down. Doc 6209 states the OTN variant plainly: "767 w/OTN... Reverses a prior posted TC 766, TOP offset reversal, when input with the same offset trace number (OTN)."

In plain terms: a plain TC 767 undoes a refundable credit that was allowed by mistake. A TC 767 carrying an OTN undoes a TOP offset reversal that Bureau of the Fiscal Service (BFS) — the agency that actually holds the offset debt data — rejected. Those are not variations on the same event; one is an internal IRS correction to a credit, the other is BFS pushing back on money the IRS tried to return from an outside debt. Reading either one as the other one misidentifies which system generated the correction and why.

The OTN variant is a restricted transaction

Doc 6209 attaches its own caution to the OTN variant: "This transaction must not be input except to correct a TC 766 on the FMS Reject Listing." ("FMS," the Financial Management Service, is the predecessor name for what is now the Bureau of the Fiscal Service.) IRM 21.4.6.5.1.2.1, TC 766 with OTN TOP Offset Reversal, carries the same restriction forward under current procedure and states it even more narrowly: "NEVER input a TC 767 to reverse a TC 766 with an OTN. Only the TOP Liaisons are authorized to input the TC 767." A TC 766 that Bureau of the Fiscal Service rejects, in whole or in part, appears on what the current IRM calls the "TC 766 Reject Listing," and clearing it is not a task any IRS employee working a case can do — it goes specifically to the TOP Liaison Office.

A TC 767 with an OTN sitting on a transcript is therefore a strong signal that a prior TOP offset reversal did not go through cleanly with Bureau of the Fiscal Service, not a routine adjustment an examiner or a data-processing correction produced on its own.

What TC 767 gets confused with

It gets confused with TC 765, the reversal code for the completely separate Earned Income Credit family (TC 764 and TC 768). The two sit close together numerically and both reverse a previously posted credit, but TC 765 has nothing to do with TC 766 or TC 767 — see that page for the EIC-specific reversal.

It is also easy to read any TC 767 as proof the client claimed a credit incorrectly. That is true only for the plain variant tied to an Examination or DP Tax Adjustment finding. The OTN variant says nothing about whether the client did anything wrong at all — it says a TOP offset reversal already in motion ran into a rejection on Bureau of the Fiscal Service's side, a data-matching or processing issue between two federal systems rather than a substantive determination about the credit.

What this means for your refund

A TC 767 means a credit you were given earlier is being taken back, and what it actually tells you depends on one detail you may not be able to see yourself: whether it carries something called an Offset Trace Number. If it doesn't, this is usually the IRS correcting a credit that was allowed by mistake. If it does, it means an earlier attempt to return money that had been taken to pay a different debt didn't go through, and the case is being handled by a specific IRS office rather than through the ordinary channels. Either way, call the number on your notice or ask a tax professional to check which situation applies before assuming you did something wrong.

The practitioner's actual next step

Check for an OTN before explaining a TC 767 to a client — the presence of an offset trace number changes what the transaction means entirely, not just its size.

If there is no OTN, trace the TC 767 back to the Examination or DP Tax Adjustment that generated it, and treat it as a credit correction rather than an offset dispute.

If there is an OTN, look for the TC 766 it corrects and treat the pair as a rejected Treasury Offset Program reversal — a matter between the IRS and Bureau of the Fiscal Service's TOP Liaison Office, not something the ordinary adjustment channel resolves.

Do not request that a client's representative input a TC 767 with an OTN, and do not expect a routine IRS phone representative to do so either — current IRS procedure restricts that specific transaction to the TOP Liaison Office.
