Trust Fund Recovery Penalty

The IRS doesn't care if you're an LLC. Under IRC § 6672, they can hold you personallyliable for unpaid payroll taxes. This guide explains the Trust Fund Recovery Penalty, how the IRS determines "responsible persons," and your defense options.

The 100% Penalty (IRC § 6672)

The Trust Fund Recovery Penalty (TFRP) is one of the most aggressive tools in the IRS collection arsenal. It allows the IRS to assess a penalty equal to 100% of the unpaid trust fund taxes against any individual who is:

  1. A "responsible person" with authority to decide which creditors to pay, AND
  2. "Willfully" failed to collect, account for, or pay over the trust fund taxes

Personal Liability

The TFRP is a personal penalty. It attaches to you as an individual, not your business. The IRS can levy your personal bank accounts, garnish your wages, and file liens against your personal property—even if your business is an LLC, S-Corp, or C-Corp.

Trust Fund vs. Non-Trust Fund Taxes

Not all payroll taxes are "trust fund" taxes subject to the TFRP. Understanding the distinction is critical:

Trust Fund Taxes (Subject to TFRP)

  • • Federal income tax withheld from employees
  • • Employee's share of Social Security (6.2%)
  • • Employee's share of Medicare (1.45%)

These are "trust" taxes because the employer holds them on behalf of the government.

Non-Trust Fund (NOT Subject to TFRP)

  • • Employer's matching share of Social Security
  • • Employer's matching share of Medicare
  • • Federal Unemployment Tax (FUTA)

These are the employer's own obligation, not held in trust.

Payment Allocation: When you make a partial payment on payroll taxes, the IRS automatically allocates the payment first to the non-trust fund portion. This maximizes your personal exposure. To avoid this, you must submit a written designation specifying that the payment applies to trust fund taxes first.

Who is a "Responsible Person"?

The IRS defines a "responsible person" under IRM 8.25.1 as someone with:

  • Duty: Authority to determine which creditors should be paid
  • Authority:Ability to direct payment of the business's funds
  • Control:Significant control over the company's finances

Common "Responsible Persons"

  • Business owners
  • Corporate officers (CEO, CFO, etc.)
  • Directors with financial control
  • Shareholders with operational role
  • Bookkeepers with check-signing authority
  • Controllers / accountants with signatory power

Multiple Responsible Persons

The IRS can—and often does—assess the TFRP against multiple individuals for the same liability. If both you and a business partner had check-signing authority, you can both be held personally liable for the full amount.

What is "Willfulness"?

Willfulness for TFRP purposes is a low bar. It does not require intent to defraud—only voluntary, conscious, and intentional failure to remit the taxes. Common scenarios that establish willfulness:

  • Paying rent, suppliers, or other creditors while payroll taxes go unpaid
  • Knowing taxes were due but deciding not to pay
  • Taking a salary while not remitting payroll taxes
  • Ignoring IRS notices or previous warnings about unpaid liabilities

What is NOT a defense:

  • "I didn't know I was responsible" (ignorance of the law)
  • "My accountant handled that" (delegation does not transfer liability)
  • "The business didn't have enough money" (if you paid other creditors first)
  • "I was only a minority shareholder" (if you had financial authority)

2026 Business Tax Updates (OBBBA)

The One Big Beautiful Bill Act (P.L. 119-21) includes several changes relevant to payroll and business taxation:

1099-NEC Threshold

$2,000

Up from $600 in 2025

SS Wage Base

$184,500

Maximum subject to 6.2%

Business Mileage Rate

70¢

per mile

1099-NEC Compliance Warning

The $2,000 reporting threshold does not change your tax obligation. Just because you don't receive a 1099-NEC for payments under $2,000 doesn't mean that income isn't taxable. The IRS uses AI-driven matching to identify unreported income.

Defense Strategies

If the IRS is investigating you for TFRP, you have several defense options:

1. Challenge "Responsible Person" Status

Prove you did not have actual authority to decide which creditors got paid. If you were a figurehead or had no real control over finances, you may not be a "responsible person."

2. Challenge "Willfulness"

If you can demonstrate that you did not know about the unpaid taxes and took immediate action upon learning, you may defeat the willfulness element. This is rare but possible in cases of fraud by a partner or employee.

3. Request an Installment Agreement

If the TFRP is valid, you may still qualify for a payment plan. Personal TFRP liabilities can be included in an individual Installment Agreement.

4. Offer in Compromise

In extreme cases, you may qualify for an OIC to settle the personal TFRP liability for less than owed. The same RCP formula applies as for other tax debts.

5. Appeal the Assessment

Before the TFRP is formally assessed, you can request an Appeals conference. After assessment, you can pay a small portion and file a refund claim to litigate in court.

The Form 4180 Interview

When the IRS investigates potential TFRP liability, they conduct interviews using Form 4180. This form documents your duties, responsibilities, and knowledge of the unpaid payroll taxes.

Critical Warning

Do not attend a Form 4180 interview without professional representation. Your answers will be used to establish "responsible person" status and "willfulness." Anything you say can and will be used against you.

Source: Form 4180

After the interview, the IRS sends Form 2751 (Proposed Assessment of Trust Fund Recovery Penalty). You have 60 days to respond and request an Appeals conference before formal assessment.

Staying in Business Compliance

If your business is struggling with payroll taxes, the worst thing you can do is ignore it. Here are strategies to stay compliant while negotiating:

  • File all returns on time, even if you can't pay the full amount
  • Deposit current payroll taxes as they become due—do not dig the hole deeper
  • Request an Installment Agreement for the back balance
  • Designate payments in writing to apply to trust fund taxes first
  • Separate personal and business finances to limit exposure

People Also Ask

Can the IRS take my personal assets for business payroll taxes?

Yes. Under IRC Section 6672, the IRS can assess the Trust Fund Recovery Penalty (TFRP) against any 'responsible person' who willfully failed to collect, account for, or pay over trust fund taxes. This penalty equals 100% of the unpaid trust fund amount and can be collected from your personal bank accounts, wages, and assets—regardless of your business structure (LLC, S-Corp, etc.).

What are 'trust fund' taxes?

Trust fund taxes are the employee portion of payroll taxes—specifically, the income tax withheld from employee wages and the employee's share of Social Security and Medicare taxes. These are called 'trust fund' taxes because the employer holds them in trust for the government. The employer's matching share of FICA is NOT a trust fund tax and is not subject to the TFRP.

Who is a 'responsible person' for TFRP purposes?

A responsible person is anyone who has authority to decide which creditors get paid. This typically includes business owners, officers, directors, shareholders with operational control, bookkeepers with check-signing authority, and anyone else who controls the company's finances. The IRS can assess the TFRP against multiple responsible persons for the same liability.

What does 'willfulness' mean for TFRP?

Willfulness for TFRP purposes means knowingly, voluntarily, and intentionally failing to remit trust fund taxes. You don't need to have intended to defraud the government—simply choosing to pay other creditors (rent, suppliers, loans) instead of payroll taxes can establish willfulness. Ignorance of the law is not a defense.

Does my LLC protect me from the Trust Fund Recovery Penalty?

No. The TFRP specifically pierces the corporate veil. Even if your business is an LLC, S-Corp, or C-Corp, you can be held personally liable for unpaid trust fund taxes if you are determined to be a responsible person who acted willfully. Entity type provides no protection against the TFRP.
