§6672 Trust Fund Recovery Penalty: When Unpaid Withholding Becomes Personal

Author: Chenchen Liu, CPA ｜ YCL Tax, Accounting & Advisory

Bottom line

Federal income tax withheld from employees and the employee share of Social Security / Medicare (together, trust-fund taxes) are treated as amounts held for the U.S. government. If a responsible person willfully fails to collect, account for, or pay over that portion, the IRS may assess the Trust Fund Recovery Penalty (TFRP) under IRC §6672—generally about 100% of the unpaid trust-fund taxes (subject to current IRS published rates/amounts and your assessment notice). It usually does not include the employer’s matching FICA. For LLC, S-corp, and startup employers in Cary / RTP, TFRP is about compliance culture and responsibility boundaries—not debt-settlement marketing. This article is education only. It does not promise penalty relief, a favorable responsible-person finding, or any personal “wipe-out.”

Background

The IRS page Employment Taxes and the Trust Fund Recovery Penalty (TFRP) explains that the TFRP can apply to people responsible for collecting, accounting for, or paying employment taxes who willfully fail to do so—often owners, officers, or others with control over payments (fact-specific). Taxpayer Advocate and related public materials describe Letter 1153 as a common proposed-TFRP letter that outlines protest / appeal paths at a high level: read the deadline and rights language; it is not an automatic final judgment. Form 4180 interviews may appear during investigations; this article names the form only and does not script answers.

The trust-fund portion generally means employee federal income tax withholding + the employee share of FICA/Medicare. Employer matching FICA and FUTA (Form 940–related) usually remain on the entity employment-tax account rather than inside the 100% TFRP trust-fund measure. Cary restaurants, clinics, and tech startups that normalize “pay vendors first, IRS later” can face Form 941 balances, §6656 deposit penalties, and personal responsible-person exposure at once. States may have parallel responsible-person concepts—clearing the federal side does not automatically clear state exposure.

What changed / options compared

Note: The comparison below contrasts common misconceptions with compliance framing, not a legislative old-vs-new chart. Amounts and procedures are subject to current IRS published rates/amounts and your Letter 1153 / assessment papers.

1. Who can be assessed

- Common misconception: Only the company can be chased; individual owners are always safe.

- Compliance framing: §6672 can assess individuals who meet the responsible-person and willfulness tests about 100% of the unpaid trust-fund portion (per your notice).

2. What “willful” means

- Common misconception: Only forged books count as willful.

- Compliance framing: Public materials describe willfulness as including knowing failure to pay despite the duty, or reckless disregard—highly factual. This article does not promise any finding.

3. Size of the penalty

- Common misconception: TFRP is a small flat fee of a few hundred dollars.

- Compliance framing: It is generally about 100% of unpaid trust-fund tax and scales with payroll—not a token fee.

4. Employer matching FICA

- Common misconception: 100% of every dollar on the 941 balance moves to the individual.

- Compliance framing: TFRP focuses on trust-fund amounts (employee withholding + employee FICA share); employer matching usually stays primarily an entity liability (IRS framing and your notice control).

5. Letter 1153

- Common misconception: Receipt means no protest is possible—or that you can ignore it.

- Compliance framing: At a high level it proposes an amount and protest/appeal timing; act by the letter’s deadline. Protest results are not promised.

6. “I didn’t sign the checks”

- Common misconception: Only the signer can be assessed; the person who actually controlled funds is safe.

- Compliance framing: Responsibility can turn on actual control and decision-making, not title alone; more than one person may be examined.

7. Vs. deposit penalties / late 941

- Common misconception: Paying a §6656 penalty or filing a late 941 erases TFRP risk.

- Compliance framing: Entity penalties and personal TFRP are different tools; catching up helps compliance but does not automatically erase a personal assessment that already meets the tests (see this series’ §6656 and late 940/941 packs).

Self-check: are you affected?

1. Your Forms 941 show unpaid balances across one or more quarters, especially withholding — Reconcile trust-fund vs. deposited amounts.

2. You are an owner, manager, bookkeeper, or the person who decides who gets paid first — Learn the responsible-person concept even if your title is not CFO.

3. You received Letter 1153 or a related TFRP proposal — Calendar the proposed amount, periods, and protest deadline; keep the full letter.

4. Tight cash flow led to delayed EFTPS while payroll continued — Reset compliance priority; skip “settlement ad” framing.

5. Multiple check-signers or EFTPS users — Clarify who knew and who decided; avoid after-the-fact blame games.

6. An LLC/S-corp closed or sold still shows 941 debt — Personal risk may not vanish when the entity dissolves (facts and procedures vary).

7. Cary / RTP startups with possible North Carolina employer balances — Track federal TFRP separately from state responsible-person paths.

Simplified example (illustrative only)

Example — Cary restaurant mid-quarter cash crunch

Assume an S-corp restaurant’s Q2 payroll taxes include about $28,000 of unpaid employee withholding + employee FICA share, with employer matching FICA tracked separately. After entity 941 collection activity, the IRS may propose TFRP at about 100% of that $28,000 trust-fund amount against a responsible person who meets the tests (figures illustrative only). Employer matching generally remains primarily on the entity account.

- If the responsible person protests by the Letter 1153 deadline with bank records, payment-priority facts, and role descriptions, the IRS will process the protest—does not promise abatement.

- Late deposits may also trigger entity §6656 ladder penalties (see related article)—a different concept from TFRP.

- Ignoring the letter can advance personal assessment and collection with fewer comfortable options.

These dollars do not calculate any real case. Your notice controls; composition and rates are subject to current IRS published rates/amounts. This article makes no debt-settlement promise and does not promise personal relief.

Action plan and timeline

1. Today: Pull recent Forms 941, EFTPS history, and payroll ledgers; label trust-fund vs. employer share.

2. If you have Letter 1153: Calendar the protest/appeal date on the letter; scan all pages; do not rely on a phone screenshot alone.

3. Stabilize compliance: Align deposits and filings with payday; do not institutionalize “vendors first, tax later.”

4. Document roles: Who approves payments, who runs EFTPS, who reviews 941—even startups need a simple authorization trail.

5. Separate entity and personal tracks: Organize company balance options apart from personal TFRP protest facts (education only—does not promise an outcome).

6. Check state parallel: Review North Carolina employer accounts for separate notices.

FAQ

Q: Does TFRP move the company’s entire employment-tax balance onto me personally?

A: It generally targets about 100% of unpaid trust-fund amounts (employee withholding + employee FICA share), and usually not employer matching FICA—per your notice and IRS framing.

Q: I am not a shareholder—only the bookkeeper. Can I still be assessed?

A: Possibly, if you had responsibility for collect/account/pay and willfulness is found—title alone is not decisive. Facts are case-specific; this article does not promise any determination.

Q: If we file and pay the entity 941 in full, does Letter 1153 vanish automatically?

A: Entity payment can affect the path forward, but a personal proposal/assessment does not always disappear on its own. Follow the letter and verify accounts; do not assume “pay the company = clear the person.”
