This article reflects federal IRS rules as of June 2026 and covers payroll figures for tax years 2025 and 2026. State responsible-person rules are noted separately. Tax law changes — confirm current figures before you act.
Quick Answer
The Trust Fund Recovery Penalty (TFRP) equals 100% of the unpaid “trust fund” payroll taxes — the income tax you withheld plus the employee’s share of Social Security and Medicare (FICA). It does not include the employer’s matching FICA, federal unemployment tax, or late-payment penalties for tax year 2025.
A business that withholds taxes from a worker’s paycheck holds that money in trust for the federal government, and when those withheld dollars never reach the IRS under section 6672, the agency can chase the people behind the business personally. The penalty is not a fine added on top of the tax — it is a dollar-for-dollar transfer of the unpaid trust fund money from the company to the individual, which means a corporation or LLC offers no shield once you are named.
This matters because the TFRP is one of the few tax debts that follows you home, survives the business closing, and cannot be wiped out in bankruptcy. The IRS pursues billions in unpaid employment taxes each year, and the IRS reports tens of billions in delinquent employment tax owed across the country, making payroll trust fund cases one of its top enforcement priorities.

What the Trust Fund Recovery Penalty Really Is
The Trust Fund Recovery Penalty is a personal assessment the IRS uses to collect withheld payroll taxes that a business failed to send in. It comes from Internal Revenue Code section 6672, which lets the government reach any person who was responsible for paying over the tax and who willfully failed to do so.
The name comes from the idea of a trust. When an employer takes income tax and FICA out of a worker’s paycheck, that money never belonged to the business — it belongs to the employee and the government, and the employer simply holds it in trust until the next deposit. The IRS treats this withheld money as property held in trust, so spending it on rent, payroll, or vendors is treated as a serious breach.
Here is the core point most owners miss: the TFRP is equal to the unpaid trust fund tax, not a percentage added on top. The penalty is 100% of the trust fund amount. If your company failed to pay $40,000 of trust fund tax, the penalty assessed against you personally is $40,000, plus interest that runs from the assessment date.
The consequence of ignoring this is severe and personal. A corporation or LLC normally protects your home, savings, and personal bank accounts, but the TFRP pierces that protection because it is assessed against you, not the business. The IRS can then file a federal tax lien against your property and levy your personal wages and bank accounts to collect.
A common misconception is that closing the business makes the problem disappear. It does not. The IRS can assess and collect the TFRP years after the company is gone, and because it is classified as a penalty for willful conduct, it is generally not dischargeable in bankruptcy.
What you should do about it is simple to state and hard to do under pressure: keep withheld payroll money untouchable, and deposit it on schedule even when cash is tight. If you cannot make a deposit, that is the moment to call a tax professional — before the missed quarter becomes a personal assessment.
Which Taxes Count — Trust Fund vs. Non-Trust-Fund
The single most important step in calculating the TFRP is splitting your total payroll tax bill into two buckets. Only one bucket is the “trust fund” that can be assessed against you personally.
The trust fund bucket is the money taken from the employee. It includes the federal income tax you withheld and the employee’s half of Social Security and Medicare. The IRS computes the penalty on the unpaid withheld income tax plus the employee’s FICA share.
The non-trust-fund bucket is the employer’s own money. It includes the employer’s matching share of Social Security and Medicare, federal unemployment tax (FUTA), and any late-payment penalties and most interest on the business account. None of this employer-side money is part of the TFRP, because it was never withheld from a worker and never held in trust.
For 2025 and 2026, the FICA rates are fixed. Social Security is 6.2% on each side (employer and employee), and Medicare is 1.45% on each side. The Social Security wage base is $176,100 for 2025 and rises to $184,500 for 2026, while Medicare has no wage cap. An extra 0.9% Additional Medicare Tax applies to high earners and is withheld from the employee, so it also falls into the trust fund bucket.
The consequence of mixing these buckets is paying the wrong number. Owners often panic and assume the whole 941 balance is personal. In reality, roughly half of the FICA portion is the employer’s own non-trust money, so the personal exposure is smaller than the total business debt — but the income tax withholding makes the trust fund portion the larger slice for most payrolls.
| Payroll Tax Component | Counts Toward Your TFRP? |
|---|---|
| Federal income tax withheld from employees | Yes — full trust fund |
| Employee Social Security (6.2%) and Medicare (1.45%) | Yes — full trust fund |
| Additional Medicare Tax (0.9%) withheld | Yes — trust fund |
| Employer Social Security and Medicare match | No — employer’s own money |
| Federal unemployment tax (FUTA) | No — never withheld |
| Late-deposit penalties and most interest | No — added to business account |
The Two Tests: Responsible Person and Willfulness
The IRS cannot assess the TFRP against just anyone at a company. Two separate tests must both be met, and the agency proves them through documents and an interview before it sends any bill.
Are You a “Responsible Person”?
A responsible person is anyone with the duty and power to collect, account for, and pay over the trust fund taxes. This is about control, not job title, so an owner, officer, partner, bookkeeper, or even an outside person can qualify if they had authority over the money.
The IRS looks at concrete signs of control: who signs checks, who has bank signature authority, who can hire and fire, who decides which bills get paid, and who signs the Form 941 employment tax return. It gathers this through corporate resolutions, bank signature cards, and the Form 4180 interview, titled “Report of Interview with Individual Relative to Trust Fund Recovery Penalty.”
The consequence here is wide reach: more than one person can be a responsible person for the same quarter, and the IRS often names everyone who fits and lets them sort it out. A common misconception is that “I was just the bookkeeper” or “I only signed checks when told” is automatic protection — it is not, because check-signing authority alone can be enough. What you should do is document the limits of your authority in writing, and during a Form 4180 interview, answer truthfully and say “unknown” rather than guess.
Did You Act “Willfully”?
Willful does not mean evil intent. It means you knew or should have known the taxes were unpaid and you chose to pay someone else — a landlord, a supplier, employees’ net wages — instead of the IRS. The courts treat a voluntary, conscious, and intentional preference of other creditors over the government as willful.
The consequence is harsh because the bar is low. If you learned mid-quarter that deposits were missed and you kept paying vendors, that is willfulness, and reckless disregard of an obvious risk also counts. A common misconception is that being short on cash is a defense; it is not, because the rule is about choice, not ability to pay everything. What you should do the moment you discover a shortfall is direct all available funds to the trust fund taxes first and keep proof of that decision.
How the Calculation Works, Step by Step
Calculating the TFRP is arithmetic once you have the payroll records. The goal is to land on the trust fund total for every unpaid quarter, because that exact number becomes your personal penalty.
- Pull each unpaid quarter’s Form 941 and payroll register so you have gross wages, income tax withheld, and FICA withheld.
- Add the federal income tax withheld from all employees for the quarter — this is fully trust fund.
- Add the employee’s share of Social Security (6.2%) and Medicare (1.45%), plus any 0.9% Additional Medicare withheld — also fully trust fund.
- Subtract any deposits the business already made that the IRS applied to the trust fund portion for that quarter.
- The remaining unpaid trust fund balance is the TFRP for that quarter; repeat for every delinquent quarter and add them together.
One nuance matters for dollars. When a business makes a voluntary payment, it can tell the IRS to apply it to the trust fund portion first, which shrinks the personal penalty. But money the IRS seizes through a levy is involuntary, and the IRS applies involuntary payments in the government’s best interest — often to the non-trust portion first, leaving your personal exposure intact.
The consequence of skipping the designation step is paying more personally than you had to. If you send the business a partial payment without a written instruction, the IRS may park it against the employer’s own FUTA and matching FICA, and your 100% trust fund number does not drop at all.
Worked Example 1 — One Quarter, One Owner
Meet Maria, who owns a small cleaning company as a single-member LLC. In the second quarter of 2025 she ran payroll but used the withheld taxes to cover supplies and rent, so nothing reached the IRS.
For that quarter her payroll register shows $120,000 in gross wages, $14,000 of federal income tax withheld, and FICA withheld from employees of $9,180 (6.2% Social Security) plus $1,740 (1.45% Medicare). No one earned near the $176,100 Social Security cap, so the full wages are taxed.
Her trust fund total is the income tax plus the employee FICA only: $14,000 + $9,180 + $1,740 = $24,920. That $24,920 is the TFRP the IRS can assess against Maria personally.
Notice what is excluded. Maria’s company also owes a matching $9,180 + $1,740 = $10,920 of employer FICA, plus FUTA and late penalties — but none of that is part of her personal penalty, because it was never withheld from workers. Maria’s personal exposure is the $24,920 trust fund slice, not the larger business balance.
Worked Example 2 — Multiple Quarters, Partial Payment
David is the president of a small manufacturing corporation. The company missed trust fund deposits across three quarters of 2025, with unpaid trust fund amounts of $18,000, $22,000, and $15,000.
Added together, the trust fund total is $18,000 + $22,000 + $15,000 = $55,000, and that full $55,000 is the proposed TFRP. David then sends a $10,000 voluntary payment from a company account and includes a written note telling the IRS to apply it to the trust fund portion of the oldest quarter first.
Because he designated the payment, the trust fund balance drops to $45,000, and that lower figure is what the IRS assesses against him personally. Interest then runs on the $45,000 from the date of assessment until he pays it off, which can add thousands more over time.
Had David let the IRS levy the $10,000 instead, the agency could have applied it to the employer’s non-trust FUTA and matching FICA, and his personal $55,000 would not have moved. The lesson is that how the money is paid changes the personal number, even when the dollar amount is identical.
Worked Example 3 — Two Responsible People
Priya and Tom are 50/50 partners in a restaurant. The business failed to pay $40,000 of trust fund tax for one quarter of 2025, and both partners signed checks and decided which bills to pay.
The IRS finds both of them are responsible and both acted willfully, so it assesses the full $40,000 against Priya and the full $40,000 against Tom. This is joint and several liability, which means each person is on the hook for the whole amount, not half.
The total the IRS collects is still capped at $40,000 — it cannot collect the penalty twice. If Priya pays the full $40,000, the IRS releases Tom, and Priya can sue Tom for contribution to recover his share under section 6672(d). The consequence is that the partner with more assets often pays first, then fights to claw back the other half privately.
Which Situation Applies to You?
The right move depends on where you sit and what stage you are in. Use this quick branch to find your path.
- You are an owner, officer, or partner who controlled the money: assume you are a likely target and focus on the willfulness facts and payment designation.
- You are a bookkeeper, controller, or check-signer who acted under orders: gather written proof you lacked final authority over which bills got paid.
- You just received Letter 1153 with Form 2751: your clock is running — protect the 60-day appeal deadline before anything else.
- The business is still open and short on cash: pay the trust fund portion first this quarter and stop the bleeding before old quarters compound.
- The business has closed: the TFRP can still be assessed against you personally, so do not assume the debt died with the company.
Forms, Deadlines, and the Appeal Window
The TFRP moves through a predictable sequence of forms, and each one carries a deadline that changes your rights. Missing a date can cost you the chance to fight the penalty at all.
It usually starts with the Form 4180 interview, where a revenue officer asks who controlled payroll, signed returns, and chose which bills to pay. This is not a formality — your answers become the evidence the IRS uses to name you, so preparation matters and saying “unknown” beats guessing.
Next comes Letter 1153 and Form 2751, the proposed assessment. From the date of Letter 1153 you have 60 days to file a written protest and request an Appeals hearing, or 75 days if the letter is addressed to you outside the United States.
The consequence of blowing the 60-day window is steep: the proposed penalty becomes an assessment, the IRS can file liens and levies, and you lose your shot at IRS Appeals before paying. After assessment, your remaining route is usually to pay a piece, file a refund claim with Form 843, and sue in federal court — a slower and costlier path.
The rough timing and cost are worth knowing. A revenue officer investigation can run several months, and professional help from a CPA or tax attorney for a TFRP defense commonly runs from a few thousand dollars to much more for litigation, while doing nothing risks the full 100% plus interest landing on you.
Does Your State Have Its Own Version?
The TFRP is federal, but most states with an income tax or sales tax have a parallel responsible-person law for unpaid state withholding and sales tax. The federal rule comes first, but a state assessment can stack on top.
Many states let the agency hold a responsible person 100% personally liable for unpaid state withholding and sales and use tax, regardless of ownership percentage. New York, for example, imposes personal liability under section 685(g) for withholding taxes when the failure to pay is willful, and like the federal penalty it is generally not dischargeable in bankruptcy.
States with no broad income tax change the picture but not entirely. A state such as Texas or Florida has no personal income tax withholding to recover, yet it can still pursue responsible persons for unpaid sales tax held in trust. Oregon’s rules let the department reach responsible officers, members, and employees for unpaid withholding, including interest and penalties.
What you should do is treat your state separately from the IRS. Confirm your own state’s responsible-person standard with your state department of revenue, because the willfulness test, the deadlines, and the appeal process often differ from the federal version.
Mistakes to Avoid
- Spending withheld taxes to cover payroll or vendors. This is the classic willful act, and it converts a cash crunch into a personal 100% penalty.
- Assuming the LLC or corporation protects you. The TFRP is personal, so the entity shield does nothing once you are named.
- Sending a partial payment with no written designation. Undesignated money may hit the non-trust portion, leaving your personal balance untouched.
- Guessing during the Form 4180 interview. A wrong guess can imply more control than you had and pull you into the assessment.
- Letting the 60-day Letter 1153 deadline pass. Missing it forfeits your IRS Appeals rights and forces you into the slower refund-suit route.
- Believing closing the business ends it. The IRS can still assess the TFRP against you years later.
- Ignoring the state version. A separate state responsible-person assessment can land on top of the federal one.
- Counting employer FICA and FUTA in your personal number. Overstating the trust fund portion means you may overpay what you actually owe.
Do’s and Don’ts
- Do deposit trust fund taxes on schedule, even when cash is tight, because they are the one bill that follows you personally.
- Do designate any voluntary payment to the trust fund portion in writing, because it directly lowers your penalty.
- Do keep records showing the limits of your authority, because they are your best defense to the responsible-person test.
- Do respond to Letter 1153 within 60 days, because it preserves your right to a hearing.
- Do call a tax professional the first time you miss a deposit, because early action shrinks the exposure.
- Don’t pay other creditors ahead of the IRS once you know deposits are missed, because that is the definition of willful.
- Don’t sign Form 2751 if you disagree, because signing agrees to the assessment.
- Don’t assume “I was only the bookkeeper” ends the inquiry, because check authority can be enough.
- Don’t let the business commingle withheld taxes with operating cash, because it makes misuse almost certain.
- Don’t ignore a state notice, because state liability is separate and equally personal.
Pros and Cons of Fighting the TFRP
- Pro: A timely protest can remove you entirely if you prove you lacked authority, saving the full 100%.
- Pro: Designating voluntary payments lowers the assessed amount before it is finalized.
- Pro: Appeals is free and often faster than court, so it preserves cash and options.
- Pro: Section 6672(d) lets you recover a co-responsible person’s share after you pay, spreading the loss.
- Pro: A strong willfulness defense can succeed when you reasonably relied on someone else to pay.
- Con: Professional defense costs money up front, sometimes several thousand dollars.
- Con: Interest keeps running on the trust fund balance during the dispute.
- Con: Losing at Appeals can leave you with the full penalty plus accrued interest.
- Con: The penalty is generally not dischargeable in bankruptcy, so it can linger for years.
- Con: Being named jointly means you may pay another person’s share first and chase them later.
What to Do Next
- Gather every unpaid quarter’s Form 941, payroll register, bank signature cards, and check-signing records.
- Calculate your true trust fund total — income tax withheld plus employee FICA only — for each quarter.
- If the business has any cash, make a voluntary payment with a written note applying it to the trust fund portion first.
- If you received Letter 1153, mark the 60-day deadline and prepare a written protest before it expires.
- Call a CPA or tax attorney now if multiple quarters, multiple responsible people, or a closed business are involved, because the stakes are personal and permanent.
FAQs
How is the Trust Fund Recovery Penalty calculated?
It equals 100% of the unpaid trust fund taxes — the income tax withheld plus the employee’s share of Social Security and Medicare. The employer’s matching FICA, FUTA, and penalties are excluded for tax year 2025.
Is the TFRP a percentage on top of the tax?
No. The penalty is dollar-for-dollar equal to the unpaid trust fund amount, not an extra percentage. If $30,000 of trust fund tax went unpaid, the penalty is $30,000, plus interest from the assessment date.
Does the employer’s share of FICA count toward the penalty?
No. Only the employee’s withheld share counts. The employer’s matching 6.2% Social Security and 1.45% Medicare are the company’s own money and stay out of your personal TFRP.
Can the IRS assess the penalty against more than one person?
Yes. Multiple responsible people can each be assessed the full amount under joint and several liability, though the IRS cannot collect more than the total unpaid trust fund tax once.
How long do I have to appeal Letter 1153?
60 days from the date of Letter 1153, or 75 days if the letter is addressed to you outside the United States. Missing this deadline forfeits your IRS Appeals rights.
Can bankruptcy wipe out the Trust Fund Recovery Penalty?
No. The TFRP is generally treated as a non-dischargeable penalty for willful conduct, so it survives most personal bankruptcies and remains your responsibility.
Does closing my business end my TFRP exposure?
No. The IRS can assess and collect the penalty against you personally for years after the company closes, because the liability attaches to the individual.
What is Form 4180?
Form 4180 is the IRS interview report used to decide who is a responsible person. A revenue officer asks who controlled payroll, signed checks, and chose which bills to pay.
Can a bookkeeper be held liable?
Yes. A bookkeeper with check-signing authority or control over which bills get paid can be a responsible person, even without an ownership stake, if they acted willfully.
Does my state have its own trust fund penalty?
Usually yes. Most states with income or sales tax impose 100% personal liability on responsible persons for unpaid state withholding or sales tax, with their own deadlines and willfulness rules.
How can I lower the penalty before it is assessed?
Designate voluntary payments to the trust fund portion in writing. This applies company money to your personal exposure first, unlike IRS levies, which the government applies in its own interest.
Does being short on cash excuse the penalty?
No. Inability to pay everything is not a defense. Willfulness turns on the choice to pay other creditors ahead of the trust fund taxes once you knew they were unpaid.
