TC 201: Identifying Number Penalty Abatement
By Forrest Baumhover, CFP®, EA · Last verified September 7, 2026
TC 201 removes the penalty for a missing taxpayer identification number, and the waiver it rests on weighs one factor heavily that has nothing to do with the failure itself — whether the same filer has been penalised before.
What the code actually does
TC 201 is the abatement of the identifying-number penalty. IRS Document 6209, Section 8A states that it “abates a previously assessed TC 200 penalty in whole or in part.” It is the paired credit to TC 200, which assesses the IRC 6723 penalty of $50 per failure for not supplying a taxpayer identification number the law required.
“In whole or in part” is more than boilerplate on this penalty, because the underlying charge is a count of discrete failures rather than a single computed amount. Where some failures are excused and others are not, the abatement covers only the excused ones — so a partial TC 201 usually reflects a successful argument about some of the omissions rather than a compromise on all of them.
The waiver standard
Relief runs through IRC 6724 rather than through the general penalty handbook. IRM 20.1.7.12 sets out the rule: “generally, an information reporting penalty under IRC 6721, IRC 6722 or IRC 6723 will be waived if it can be shown the error was due to reasonable cause and not due to willful neglect. 26 CFR 301.6724-1 provides the general provisions that must be met to establish reasonable cause.” The regulation, not the IRM, is where the substantive test lives, and it asks the filer to show both significant mitigating factors or events beyond their control and that they acted in a responsible manner before and after the failure.
One factor is called out for particular weight, and it is worth raising with a client before the request goes in: IRM 20.1.7.12 states that “significant consideration is given to if the filer was previously penalized under IRC 6721, IRC 6722, or IRC 6723.” That is a cross-provision history, so penalties for information returns or payee statements count against a request about identifying numbers. A client with a pattern is in a materially weaker position than the facts of the current failure alone would suggest, and a first-time filer in a stronger one — but note that this is a judgment factor in the waiver analysis, not the defined administrative waiver that applies to the failure-to-file, failure-to-pay and failure-to-deposit penalties.
The better argument, where it is available
Before reaching the waiver at all, it is worth testing whether the penalty should have been assessed. IRM 20.1.7.10.1 provides that “an inconsequential error or omission is not considered a failure to comply with a specified information reporting requirement. Therefore, the penalty shall not be assessed,” with “inconsequential” meaning a failure that does not make it difficult for the IRS to put the information to its intended use or prevent a payee from receiving correct information in time to report it.
That argument is stronger than the waiver in two respects. It does not require the client to explain their conduct or produce evidence of responsible behaviour, and it is not weakened by a prior penalty history — an inconsequential omission is not a failure regardless of what happened in earlier years. Where a number was supplied late but in time to be used, or supplied in a slightly wrong format that did not impede anyone, that is the argument to lead with. The count is also worth auditing: the penalty is imposed per requirement missed, so an assessment resting on an inflated count can be reduced arithmetically without any relief analysis at all.
What TC 201 gets confused with
TC 201 gets confused with abatements of the larger information return penalties under IRC 6721 and IRC 6722, which share the same IRM chapter and the same IRC 6724 waiver. The penalties differ in scale and in process — those are indexed for inflation and are administered through the Notice 972CG cycle, while this one is a flat $50 per failure — so a practitioner who follows the 972CG reply route for a TC 200 assessment is answering the wrong process, and one who expects an indexed figure will not reconcile the amount.
It is also assumed to be reachable by First-Time Abate, which it is not. The administrative waiver is defined against the failure-to-file, failure-to-pay and failure-to-deposit penalties, and information reporting penalties sit outside it. What can look similar is the prior-penalty factor described above — a clean history does help here — but it helps as one consideration inside a reasonable-cause analysis rather than as an entitlement, and a request framed as though the waiver applied invites a denial on the wrong grounds.
The practitioner’s actual next step
Audit the failure count before arguing anything, since the penalty is per requirement missed and an inflated count is corrected arithmetically.
Lead with the inconsequential-error exception where the omission did not impede the IRS or a payee, because it defeats the penalty without reaching the client’s conduct.
Where the waiver is needed, build it against 26 CFR 301.6724-1 — mitigating factors or events beyond the filer’s control, plus responsible behaviour before and after the failure.
Check the client’s history across IRC 6721, 6722 and 6723 first, since a prior penalty under any of the three is given significant weight against the request.
Do not cite First-Time Abate, and confirm what remains assessed on the module with the IRS Transcript Decoder before treating a partial abatement as a final outcome.
