What Form 4180 is
Form 4180 is the document a revenue officer completes while interviewing someone who may be personally liable for a business's unpaid trust fund taxes. The IRS's manual describes its purpose:
“The purpose of the personal interview and completion of Form 4180 is to secure direct, detailed information regarding the individual's or other person's involvement in the business in order to determine if they meet the criteria for responsibility ... and willfulness ... The questions on the form are intended as a guide and are not all inclusive; supplemental questions may be asked.” — Internal Revenue Manual 5.7.4.2.4(2)
Three things follow from that description and each one is practical.
It is evidence, not a determination. Nothing is decided at the interview. What is decided is what goes on the record about you, and the determination happens later, on the strength of it.
The questions are a guide and not a limit. Supplemental questions may be asked, so preparing answers to a list would not be sufficient even if the list were available.
More than one person is interviewed. The officer is instructed to “attempt to personally secure Form 4180 from all potentially responsible persons” — which means the account of who had authority is being assembled from several people who may not agree.

Why you cannot see the form first
The instruction is direct and it is worth reading in full, because it changes what preparation can consist of:
“Do not give or mail Form 4180 to the potentially responsible person(s) or representative for completion by that person or for review prior to the interview. The form must be completed in person or over the phone. Letter 3586, Meeting Scheduled with Individual for TFRP Interview, can be used to schedule an appointment to conduct a 4180 interview.” — Internal Revenue Manual 5.7.4.2.4(3)
And the IRS does not publish the form. We looked, systematically, on 6 September 2026: the “About Form 4180” page, the standard form addresses, the accessible-format address, the prior-year archive, and both of the IRS's own form pick-lists. All returned nothing. The IRS's forms database search for 4180 reports “Showing 0 - 0 of 0.” The related forms in the same series — 2750, 2751 and 2751A — are unpublished on the same searches.
Copies of old revisions circulate on practitioner websites. We do not link to them and we would not prepare from them, because there is no way to know how far a version from an unknown year has drifted from the one on the officer's screen, and a rehearsed answer to a question that has been reworded is worse than no rehearsal.
What this does mean, and it is the useful inversion. The interview is designed so that the answers are unrehearsed. That is a reason to have a representative rather than a script, and it is the actual argument for representation on this page rather than a sales one.
What the interview is testing
Two findings, both required. If either fails, the penalty does not attach to you.
Responsibility. The manual's own criteria:
“A responsible person has: Duty to perform; Power to direct the act of collecting trust fund taxes; Accountability for and authority to pay trust fund taxes; Authority to determine which creditors will or will not be paid.”
And the list of people the officer is told to identify:
“Are officers, directors, or shareholders of the corporation; Hire and fire employees; Exercise authority to determine which creditors to pay; Sign and file the excise tax or employment tax returns, such as Form 941, Employer's Quarterly Federal Tax Return; Control payroll/disbursements; Control the corporation's voting stock; Make federal tax deposits.”
Notice what is not on that list: ownership. A minority shareholder with signing authority can be responsible. A majority owner with no operational authority may not be. The test is about decision-making, not title.
And the manual says so twice, in the taxpayer's favor, in the subsection immediately after the one just quoted. IRM 5.7.3.4.1.1: “If a person is an officer or owns stock in the corporation, this cannot be the sole basis for a responsibility determination,” and “If a person has the authority to sign checks, the exercise of that authority does not, in and of itself, establish responsibility” — signature authority “may be merely a convenience.”
The provision most likely to matter to you, and it is almost never published
IRM 5.7.3.4.1.2 deals with non-owner employees, and it rests on the IRS's own Policy Statement 5-14: “individuals performing ministerial acts without exercising independent judgment will not be deemed responsible.” The manual works the example directly — a bookkeeper who signs checks only under direction and cannot independently decide which bills are paid is performing a ministerial act and “should generally not be held responsible for the TFRP.”
The standard the manual states is “significant control” over the company's finances — more than mechanical check-signing, more than clerical duty. If you carried out instructions rather than set priorities, that is the language your account of events should be built on, and it is the IRS's own language rather than an argument you are inventing.
Willfulness, and this is the finding people misunderstand:
“Willful means intentional, deliberate, voluntary, reckless, knowing, as opposed to accidental. No evil intent or bad motive is required. To show willfulness, the government generally must demonstrate that a responsible person was aware, or should have been aware, of the outstanding taxes and either intentionally disregarded the law or was plainly indifferent to its requirements. A responsible person's failure to investigate or correct mismanagement after being notified that withholding taxes have not been paid satisfies the TFRP ‘willfulness’ element.” — Internal Revenue Manual 5.7.3.4.2
Two sentences in that passage do most of the work.
“No evil intent or bad motive is required” is the one people argue with, and arguing with it in the room is the least productive thing that can happen there. Paying the landlord to keep the doors open, with entirely good intentions, while the deposits went short, is the standard case rather than a defense to it.
“Failure to investigate or correct mismanagement after being notified” is the one that catches people who delegated. Being told the taxes were unpaid and not checking is itself the finding. It is also why “my bookkeeper handled it” is a starting point rather than an answer.
The same subsection then names three situations where the manual tells its own staff willfulness is hard to establish, and they are worth knowing by name because they are the places the argument is winnable: an assessment arising from Combined Annual Wage Reporting, an employment tax adjustment made under IRC 3509, and a volunteer director or trustee of a tax-exempt organization, where the IRS may need to show actual knowledge under IRC 6672(e).
How the form is structured
We cannot quote the questions. We can tell you the shape, because the manual describes it:
| Part | What it covers |
|---|---|
| Page 1 | "core willfulness and responsibility questions" — and it can stand alone as an abbreviated interview where there is one responsible person or a simple structure. The signature can be taken on page 1. |
| Page 2, Sections IV and V | Completed when the person says others had authority. |
| Page 3, Section VI | Payroll Service Provider and Professional Employer Organization questions. |
| Page 3, Section VII | Excise tax cases only. |
| Page 4 | Narrative space, and the signature when pages 2 or 3 are used. |
One group is taken out by statute rather than by argument. Section 6672(e) exempts an unpaid, volunteer board member of a tax-exempt organization who is “solely serving in an honorary capacity,” does not participate in day-to-day or financial operations, and has no actual knowledge of the failure. All three, together. If that is you, say it at the start of the interview rather than at the end.
The most consequential thing in that table is not obvious. Answering page 1 in a way that names other people with authority is what opens Sections IV and V. Answering it in a way that does not is what makes page 1 the whole interview — with you as the only person on the record as having had authority.
The officer is also instructed to provide Notice 609, the Privacy Act Notice, during the interview, and to give you a copy of the signed form afterwards where feasible. Ask for the copy.
