After 32 years of IRS work — and more than $100 million in resolved tax debt — I've seen just about every version of the problem you're dealing with. I'm Darrin Mish, a tax attorney in Tampa. Here's what you should know.
The Penalty That Can Outlive Your Business
If your business has unpaid payroll taxes, there is one thing more dangerous than the corporate liability itself. The Trust Fund Recovery Penalty (TFRP) under Internal Revenue Code Section 6672 makes specific individuals personally liable for the trust fund portion of the unpaid payroll taxes.
Personally liable. Not the business. You.
After 32 years of working tax controversy cases, I can tell you that the TFRP is the most damaging single assessment the IRS issues against individuals. It can survive the death of the business, survive bankruptcy in most cases, and follow you for 10 years or longer.
Here is exactly how it works, who qualifies as a “responsible person,” and what to do if you have been threatened with assessment.
What the Trust Fund Recovery Penalty Actually Is
Under Internal Revenue Code Section 6672, the IRS can assess a 100% penalty against “any person required to collect, truthfully account for, and pay over any tax” who willfully fails to do so. The 100% refers to the trust fund portion of unpaid payroll taxes.
Two key concepts.
Trust fund taxes. When you pay an employee, you withhold their share of Social Security and Medicare taxes (FICA), federal income tax withholding, and other deductions. That money is held in trust for the federal government until you remit it. It was never your money. The trust fund portion is the employee’s share of FICA plus federal income tax withholding.
The non-trust fund portion is the employer’s matching share of FICA and federal unemployment taxes. That is the employer’s own liability. The TFRP does not apply to the non-trust fund portion.
If your business has $400,000 in unpaid payroll taxes, perhaps $250,000 of that is trust fund and $150,000 is non-trust fund. The IRS can assess the $250,000 trust fund portion against each responsible person individually under Section 6672.

Two Elements: Responsibility and Willfulness
The IRS has to prove both elements before assessing the TFRP. Both matter.
Responsibility
A “responsible person” under Section 6672 is anyone with the duty and authority to collect, account for, and pay over the trust fund taxes. The IRS interprets this broadly.
Specific factors the IRS considers (set out in IRM 5.7.3 and case law):
- Who has check-signing authority?
- Who has authority to decide which creditors get paid first?
- Who supervises the payroll function?
- Who manages day-to-day financial operations?
- Who has authority to hire and fire employees handling money?
- Who has authority to sign tax returns?
- Who controls bank accounts?
- Who makes business policy decisions?
You do not have to be the owner. You do not have to have a majority interest. You do not have to be on the board of directors. You can be a CFO, controller, bookkeeper with check-signing authority, outside accountant, spouse who helps with the business finances, manager, or anyone else with meaningful financial control.
The IRS can assess the TFRP against multiple people for the same liability. The penalty is joint and several. Each person can be held liable for the full amount, and the IRS can collect from any combination of them.
Willfulness
The IRS also has to prove willfulness. In TFRP context, willfulness has a specific meaning: knowing the trust fund taxes were due and unpaid, and consciously choosing to pay something else (employees, vendors, rent, owner draws) instead.
This is a low bar. Willfulness does not require bad intent. It does not require an intent to cheat the government. It just requires:
- The responsible person knew the trust fund taxes were unpaid, and
- The responsible person made a conscious choice to use available money for something else.
Almost every payroll tax case meets this standard. The moment the owner signs payroll checks while knowing the trust fund deposits are behind, the willfulness element is satisfied.
The exceptions are narrow. If the responsible person genuinely did not know about the unpaid taxes (because of fraud by another officer or employee), willfulness is harder to prove. If the responsible person had no actual authority to decide which bills got paid (because someone else above them controlled all financial decisions), willfulness may not attach.
For more on the willfulness standard and the cases where it fails, the IRS’s own IRM 5.7.3 is the operative reference, and case law provides guardrails.
The Form 4180 Interview
When the IRS investigates a TFRP case, the central piece of evidence is the Form 4180 interview. A Revenue Officer interviews each person who might be a responsible person and asks detailed questions about:
- Job duties and authority
- Who else had financial control
- Check-signing practices
- Bank account control
- Which creditors got paid and when
- Who knew about the unpaid taxes
- What was paid instead
The Form 4180 answers form the factual basis for the IRS’s assessment decision.
This is the most important moment in any TFRP case. Statements made in the 4180 interview directly determine who gets assessed. Inconsistent statements between different interviewees can lead to all of them being assessed jointly and severally.
Never participate in a Form 4180 interview without representation. The questions look simple but have specific legal implications. An attorney who handles TFRP cases regularly can help frame the answers accurately while not volunteering information that creates assessment risk for the client.
What Happens After Assessment
If the IRS concludes that the TFRP applies and proceeds with assessment, the procedure unfolds in stages.
Step 1: Letter 1153 (Proposed Trust Fund Recovery Penalty Notice). The IRS sends this letter to anyone they propose to assess. The letter explains the proposed penalty amount and the underlying calculation. The recipient has 60 days to respond.
Step 2: Form 2751 (Proposed Assessment of Trust Fund Recovery Penalty). If the proposed assessment is not contested, the IRS sends Form 2751 finalizing the assessment.
Step 3: Appeal rights. Within the 60-day window after Letter 1153, the responsible person can file a written protest requesting an Appeals conference. This is critical. The IRS Appeals office has authority to settle TFRP cases based on hazards of litigation. Many TFRP assessments get reduced or eliminated at Appeals.
Step 4: Tax Court or refund litigation. If Appeals does not resolve the case, the responsible person can either pay a portion of the TFRP and sue for refund in federal District Court or Court of Federal Claims, or follow the divisible tax rule (paying tax on one employee for one quarter and litigating).
The procedural defenses matter. Many people lose TFRP cases not because they were responsible and willful, but because they missed the 60-day window to contest.
What Survives the Business and What Does Not
This is what makes the TFRP particularly dangerous.
The TFRP survives business closure. If you close the business or it goes out of business, the TFRP against you personally does not go away. The IRS still has 10 years from assessment to collect from you.
The TFRP survives business bankruptcy. Filing Chapter 7 or Chapter 11 for the business does not eliminate the personal TFRP liability of responsible persons.
The TFRP survives most personal bankruptcies. Trust fund tax debt is generally non-dischargeable under 11 U.S.C. Section 523(a)(1)(B)(ii). You can file Chapter 7 and your other tax debts may discharge while the TFRP remains.
The TFRP can be collected through:
- IRS levy on your wages
- IRS levy on your bank accounts
- IRS levy on Social Security under the Federal Payment Levy Program
- Federal tax lien on your real and personal property
- Seizure of business assets even if the business is now owned by someone else, in specific cases
The 10-year Collection Statute Expiration Date applies (Internal Revenue Code Section 6502), but it counts from the assessment date, not from when the underlying payroll taxes were due.
How to Defend Against the TFRP
Defending against a TFRP assessment has several possible paths.
Defense 1: Not a responsible person. If you did not have meaningful control over the financial decisions, you may not be a responsible person. Document the specific limitations on your authority. This works best for employees with limited check-signing or banking access who took orders from above.
Defense 2: No willfulness. If you genuinely did not know the trust fund taxes were unpaid, willfulness may not attach. This is hardest to prove because the IRS presumes awareness for anyone with financial responsibility. It can work when someone above you in the chain actively concealed the unpaid taxes.
Defense 3: Limited responsibility for specific periods. Even if you were responsible during some quarters, you may not have been during others (because you joined the business later, took medical leave, or had reduced responsibilities). The TFRP applies quarter by quarter. Limit the assessment to the periods where you actually had control.
Defense 4: Procedural challenges. Did the IRS provide the required notices? Did they interview you under Form 4180? Were the proposed assessments calculated correctly from the actual trust fund portion? Procedural errors can invalidate assessments.
Defense 5: Settlement at Appeals. Even when responsibility and willfulness are clear, the IRS Appeals office can settle TFRP assessments based on hazards of litigation. A well-presented Appeals case often reduces the assessment.
What to Do If You Receive Letter 1153
If you have received Letter 1153, the IRS has formally proposed a TFRP assessment against you personally.
Step 1: Calendar the 60-day deadline. The protest must be filed within 60 days of the letter date. Mark it.
Step 2: Pull the underlying calculation. Request the IRS’s calculation of the trust fund portion. Compare it to your records. The IRS sometimes assesses against the wrong amounts.
Step 3: Identify your defenses. Were you really a responsible person? When? Did you know about the unpaid taxes? What was your actual authority?
Step 4: File a written protest. A written protest must include specific information identified in IRS guidance (the items in dispute, the factual basis, the legal arguments, supporting documentation). Working with a tax attorney significantly improves the quality of the protest.
Step 5: Prepare for the Appeals conference. If the protest is timely filed, the case goes to Appeals. Appeals officers settle based on hazards of litigation, which means well-presented defenses can reduce or eliminate the assessment.
When to Get Professional Help
For TFRP cases, professional help is not optional. The technical complexity (responsible person analysis, willfulness analysis, procedural defenses, Appeals strategy) requires someone who handles these cases regularly.
Get help immediately if:
- You have received Letter 1153 or Form 2751
- A Revenue Officer has requested a Form 4180 interview
- You are being interviewed about another responsible person
- Your business has unpaid 941 taxes and you want to evaluate personal exposure
The cost of bad TFRP handling is personal financial ruin. The cost of professional handling is a fraction of that.

The Bottom Line
The Trust Fund Recovery Penalty makes individuals personally liable for the trust fund portion of unpaid payroll taxes. It survives business closure, survives bankruptcy, and follows you for years.
The IRS must prove both responsibility and willfulness. The 4180 interview is the most important moment in any case. The 60-day window after Letter 1153 is the critical defense opportunity.
The TFRP can be defended. But the defense has to start immediately. Days matter.
