TC 311: Tip Income Penalty Abatement
By Forrest Baumhover, CFP®, EA · Last verified September 7, 2026
TC 311 removes the tip-reporting penalty, and the IRM is unusually prescriptive about how to earn one — a written statement of every fact relied on, sworn under penalties of perjury when it answers a proposed assessment.
What the code actually does
TC 311 abates the penalty for failing to report tip income. IRS Document 6209, Section 8A states that it “abates previously posted unreversed TC 310, in whole or in part,” and IRM 20.1.10.6.2.2 names it in the same list that names the assessment code, recording that the penalty is “assessed with Transaction Code (TC) 310” and “abated with TC 311.” IRM 20.1.10.6.2.3 confirms the input: “the penalty is abated on IDRS using TC 311.”
The word “unreversed” matters on an account with a history. A TC 311 reaches a TC 310 that is still standing, so on a module carrying several assessments and abatements the reconciliation has to be done against the current net rather than against the original figure.
The relief standard, and the form it has to take
IRC 6652(b) builds the exception into the penalty itself: it applies “unless the failure was due to reasonable cause and not willful neglect,” in IRM 20.1.10.6.2’s words. So this is not a discretionary waiver layered on top of a penalty that otherwise applies — reasonable cause is part of the provision, and establishing it means the penalty does not apply at all.
The procedural requirements are unusually specific for a penalty of this size. IRM 20.1.10.6.2.3 requires that “the explanation of why tips were not reported must be made in the form of a written statement setting forth all the facts alleged as reasonable cause.” It permits that statement to be attached to the employee’s Form 1040, pointing to Form 4137. And it adds a condition that is easy to miss and fatal to overlook: “if the statement is submitted in response to a notice regarding a proposed penalty assessment, the statement must contain a declaration that it is made under penalties of perjury.”
Two practical consequences follow. A statement filed proactively with the return does not need the perjury declaration; one filed in answer to a proposed assessment does, and omitting it gives a caseworker a clean procedural reason to set the request aside without reaching the merits. And “all the facts alleged” is a completeness requirement — a partial account invites a denial that is difficult to supplement later.
What actually supports the argument
The reasonable-cause analysis here is shaped by what the reporting duty actually asks of an employee, so the strongest facts tend to be about the reporting mechanics rather than about hardship generally. The duty under IRC 6053(a) is to give the employer a written statement of cash tips of $20 or more in a month, by the 10th of the following month. Facts that bear on whether ordinary business care and prudence was exercised in meeting that duty include an employer that never provided a reporting mechanism, a tip-sharing arrangement whose amounts the employee could not determine, and confusion about which categories count — charged tips distributed by the employer do, non-cash tips do not, and tips under $20 from each of several employers in a month require no report at all.
A client who in fact reported all the tips they received, or who received less than the threshold from each employer, is not making a reasonable-cause argument but a factual one that the penalty does not apply. That is the better position where it exists, and it should be pleaded first. It is also worth confirming that the underlying employment tax has been addressed, since TC 310 and the FICA tax on the same tips are separate assessments and abating the penalty leaves the tax untouched.
What TC 311 gets confused with
TC 311 gets confused with an abatement of the tax on the unreported tips. It is not one. The penalty and the employee-share FICA tax are separate liabilities on the same module, and a client who sees a TC 311 and still owes will usually be looking at the tax, correctly assessed and unaffected by the abatement.
It is also assumed to be reachable by First-Time Abate, which reflects a reasonable generalisation from the penalties practitioners meet most often. The administrative waiver is defined against the failure-to-file, failure-to-pay and failure-to-deposit penalties, and does not extend to this one — the route here is the statutory reasonable-cause exception in IRC 6652(b) itself, argued on written facts. A request built on a clean compliance history rather than on why the tips went unreported is answering a question this provision does not ask.
The practitioner’s actual next step
Check first whether the penalty applies at all — full reporting, or under $20 a month from each employer, is a factual defence and beats a reasonable-cause argument.
Put the explanation in writing, covering every fact relied on, because the IRM requires a written statement and treats completeness as part of the standard.
Include the penalties-of-perjury declaration whenever the statement answers a proposed assessment notice, since its absence is a procedural ground for rejection.
Do not frame the request as First-Time Abate. The relief here is the statute’s own reasonable-cause exception, and the administrative waiver does not reach this penalty.
Confirm the employment tax has been dealt with separately, and verify what the abatement actually cleared on the module with the IRS Transcript Decoder before telling the client the matter is closed.
