If a business fell behind on payroll taxes, the revenue officer’s investigation eventually becomes a conversation — and Form 4180, Report of Interview with Individual Relative to Trust Fund Recovery Penalty or Personal Liability for Excise Taxes (Rev. 8-2012), is the record of it. The interview is where the IRS builds the file that decides whether you are proposed for the trust fund recovery penalty. This page walks the interview itself: who gets called in, how it is conducted and recorded, the question families in the form’s own order, and what you sign at the end. What the interview is testing — the responsible-person and willfulness tests and the penalty computation — lives in the payroll tax penalties guide and the business tax resolution guide; this page owns the room, not the tests.
General information, not tax or legal advice. The form’s structure and signature language below are from Form 4180 (Rev. 8-2012) and IRM 5.7.4; an interview that could make you liable is a standard point to bring in a representative.
Form 4180 is the revenue officer’s record of a personal interview, prepared by the interviewer in person or by telephone. It is not a form you file, and not one you fill in alone in advance. Its purpose (IRM 5.7.4.2.1) is to secure direct, detailed information about your involvement in the business — and everyone else’s — for the responsibility and willfulness determinations; the printed questions are a guide, not a closed list, and the officer may ask more. The officer attempts to secure a Form 4180 from all potentially responsible persons — not only the person ultimately proposed for assessment.
Page 1 carries the core questions and can serve as an abbreviated interview where there is only one responsible person or the structure is uncomplicated; otherwise the remaining sections open up.
| Section | Question family | What the officer is recording it for |
|---|---|---|
| I — Person Interviewed | Your identity, position, and dates in the role | Fixing who is examined, and for which periods |
| II — Responsibilities | The duty inventory (below), each with the periods you performed it — and who else performed it | The responsibility picture: who held which levers, and when |
| III — Signatures | The page-1 sign-off for the abbreviated interview | Certifying the abbreviated record (see “What you sign”) |
| IV — Business Information | Positions in the business and who held them; who signs Form 941; e-file details | Corroborating Section II against the business’s structure |
| V — Knowledge / Willfulness | Whether other bills were paid while taxes mounted; who authorized them; when and how you first learned the taxes were unpaid; what you did then | The willfulness picture: knowledge plus other creditors paid first |
| VI — Payroll Service Provider / PEO | Completed only if a third-party payer handled payroll | Whether reliance on a provider explains — or fails to explain — the nonpayment |
| VII — Personal Liability for Excise Tax Cases | The excise-tax liability questions | The parallel record for excise cases |
| VIII — Signatures | The full-form sign-off | Certifying the complete record |
Section II is the heart of page 1. For each duty, the form asks whether you performed it and during what periods: determine financial policy; direct or authorize payment of bills; open or close bank accounts; guarantee or co-sign loans; sign or countersign checks; authorize or sign payroll checks; authorize or make federal tax deposits; prepare, review, sign or transmit payroll returns; hire and fire — plus signature authority or a PIN on business accounts. For every duty, the form’s other column asks the question that defines the interview: who else performed this? Your answers about colleagues become part of their records too.
Section V is where interviews are usually decided. The officer asks whether rent, mortgage, utilities, loans, and vendors were paid while the taxes went unpaid; whether payrolls were met and who authorized them; who funded net payroll; when and how you first learned the taxes were unpaid; what you did, once you knew, to see they were paid; and whether nonpayment was ever discussed, and by whom. Answers that establish “I knew, and the money went to other creditors anyway” are the raw material of a willfulness finding — which is why preparation belongs before this conversation.
The form’s final page leaves narrative space for your own statement and records the handouts given — Notice 609 (Privacy Act) and Notice 784.
In Section III (abbreviated interview) or Section VIII (full form), you sign this declaration: “I declare that I have examined the information given in this interview and to the best of my knowledge and belief, it is true, correct, and complete.” Note what it does not say: Form 4180 is not signed “under penalties of perjury” — that declaration belongs to a different document in this process (the formal written protest in the Letter 1153 guide, per IRM 5.7.6.6). Both the person interviewed and the interviewer sign and date, and the form records the date a copy of the completed interview was given to you.
The interview feeds the officer’s assertion recommendation on Form 4183, which a manager must approve. If assertion is recommended, the output is a Letter 1153 with Form 2751 proposing the assessment against you personally — and its 60-day protest clock starts.
You may be represented at the interview under a Form 2848 power of attorney, and under §7521(b)(2) a person being interviewed by an IRS officer may suspend the interview at any time to consult a qualified representative. A representative should be engaged before the interview, not retained to repair it afterward. And declining is not a shield — the IRS must request the interview, but it is not required to complete one to propose an assessment; an un-interviewed person can still receive a Letter 1153 built on other evidence.
What questions are asked at a 4180 interview? The form’s own families: your duties and the periods you performed them (bill payment, bank accounts, check-signing, payroll checks, tax deposits, payroll returns, hiring and firing), who else performed each duty, and the knowledge questions — whether other obligations were paid while taxes mounted, and when and how you first learned the taxes were unpaid.
What happens during the 4180 interview? A revenue officer interviews you in person or by phone and records the answers on Form 4180. Page 1 may complete an abbreviated interview; otherwise the form continues through its remaining sections and ends with signatures from both you and the interviewer and a copy for you.
Does the IRS ask about other business payments at a 4180 interview? Yes — Section V asks directly whether rent, mortgage, utilities, loans, and vendors were paid while the taxes went unpaid, and who authorized those payments. Those answers go to willfulness: paying other creditors while knowing payroll taxes are owed is the pattern the IRS looks for.
Who else performed this duty — why does the IRS ask who else had authority? Because responsibility can be shared. The form’s “who else” column maps everyone who held each duty, and the officer seeks a Form 4180 from all potentially responsible persons. Naming others does not remove you — each person is assessed on their own involvement — but the map decides who gets proposed at all.
Do I have to sign the Form 4180 at the end of the interview? The form’s signature sections (III for the abbreviated interview, VIII for the full form) have both the interviewee and the interviewer sign a declaration that the information given is true, correct, and complete to the best of the signer’s knowledge — it is not a “penalties of perjury” declaration. Review the record before signing; it becomes the basis for the officer’s recommendation.
