Trust Fund Recovery Penalty —
Personal Liability for Unpaid Payroll Taxes
The Trust Fund Recovery Penalty (TFRP) is one of the most aggressive collection tools the IRS has. It lets the government move past your business and hold you personally responsible for the payroll taxes your company withheld but never paid over. If you owned, ran, or even helped manage the books of a business with unpaid 941 taxes, the IRS may be building a case against you right now. See our flat-fee pricing →
The Trust Fund Recovery Penalty, authorized by Internal Revenue Code Section 6672, lets the IRS assess the unpaid "trust fund" portion of payroll taxes — the income tax and employee share of Social Security and Medicare withheld from paychecks — directly against individuals. The IRS can pursue anyone who is both a responsible person and who acted willfully. The liability is personal, pierces the corporate veil, and cannot be discharged in bankruptcy. If you are facing a Form 4180 interview or a proposed assessment, defenses exist — but acting early matters.
What Is the Trust Fund Recovery Penalty?
When an employer runs payroll, it withholds federal income tax and the employee's share of Social Security and Medicare (FICA) from each paycheck. Those withheld amounts never belonged to the business — they are held "in trust" for the government until they are deposited. That is why they are called trust fund taxes. The employer reports them on Form 941, the Employer's Quarterly Federal Tax Return.
When a struggling business uses that withheld money to pay rent, suppliers, or other bills instead of remitting it to the IRS, the government treats it almost like theft. IRC Section 6672 gives the IRS the power to recover that money personally from the individuals behind the decision. The penalty equals 100% of the unpaid trust fund taxes — which is why it is sometimes called the "100% penalty." Note that the penalty covers only the trust fund portion, not the employer's matching share of FICA or federal unemployment tax.
Who Can Be Held Liable: The Two-Part Test
The IRS cannot assess the TFRP against just anyone. It must prove two things about you. Both must be true before you can be held personally liable.
How the IRS Investigates: The Form 4180 Interview
When a business falls behind on payroll taxes, a revenue officer is assigned to identify who should be held responsible. The centerpiece of that investigation is Form 4180, the "Report of Interview Used in the Determination of the Trust Fund Recovery Penalty." The officer will interview each potential responsible person, asking detailed questions about your duties, your check-signing authority, who handled the books, who decided which bills got paid, and when you first learned the taxes were unpaid.
Your answers go straight into the IRS's determination. People often unintentionally admit to responsibility and willfulness because they do not understand the legal weight of the questions. Before you sit for a Form 4180 interview, it is wise to understand exactly what each question is designed to establish — and, in many cases, to have a representative present.
If the officer concludes you are liable, the IRS issues Letter 1153 and Form 2751, proposing the assessment against you. You generally have 60 days to appeal before the penalty is formally assessed and the IRS can begin collecting from your personal wages, bank accounts, and assets.
Why the TFRP Is So Dangerous
Defense and Resolution Options
A proposed TFRP is not the final word. Depending on the facts, several paths can reduce or eliminate your exposure:
Many TFRP cases involve small business owners and the self-employed who fell behind during a cash crunch. If your situation overlaps with personal tax debt, see our guidance on self-employed tax debt and explore whether an Offer in Compromise could settle the personal liability for less than the full balance.
Frequently Asked Questions
Who can be held personally liable for the Trust Fund Recovery Penalty?
Under IRC Section 6672, any person the IRS deems a responsible person who willfully failed to collect, account for, or pay over withheld payroll taxes can be held personally liable. This includes business owners, corporate officers, partners, bookkeepers, payroll clerks, and anyone with authority to sign checks or decide which creditors get paid. Liability is personal and survives the closure or bankruptcy of the business.
What is Form 4180 and why is the IRS interviewing me?
Form 4180 is the Report of Interview Used in the Determination of the Trust Fund Recovery Penalty. A revenue officer uses it to question you about your role in the business, your check-signing authority, and your knowledge of the unpaid taxes. The answers help the IRS decide whether you are a responsible person who acted willfully. Your answers can be used to assess the penalty against you, so it is wise to prepare or consult a professional before the interview.
Can the Trust Fund Recovery Penalty be discharged in bankruptcy?
No. The trust fund portion of payroll taxes is generally a non-dischargeable priority tax, and the personal liability assessed under IRC 6672 cannot be wiped out in bankruptcy. Because the penalty pierces the corporate veil, closing the business does not eliminate it either. Realistic resolution paths include contesting responsibility or willfulness, appealing the assessment, an installment agreement, or an Offer in Compromise.
