Why the TFRP is different

Most IRS penalties stay with the business. The Trust Fund Recovery Penalty, under IRC §6672, is the exception that pierces it. When an employer withholds income tax and the employee's share of Social Security and Medicare from paychecks, that money is held in trust for the government. If it isn't paid over, the IRS can assess the entire trust-fund amount — 100% — against the individuals responsible, personally.

IRS Code Section
IRC §6672
Penalty Amount
100% of the unpaid trust-fund taxes
What's "Trust Fund"
Withheld income tax + employee share of FICA
Who Can Be Liable
Any "responsible person" who acted "willfully"
Key IRS Form
Form 4180 (responsibility/willfulness interview)
Proposed Via
Letter 1153 + Form 2751 — 60 days to appeal
Liability Type
Personal; joint and several; survives bankruptcy

Note what the penalty does not include: the employer's matching share of FICA and federal unemployment tax aren't trust-fund money, so they stay with the business. But the withheld portion — the part that came out of your employees' checks — is exactly what the IRS pursues personally.

The two-part test: responsible & willful

The IRS can only assess the TFRP against someone who is both a responsible person and who acted willfully. Both prongs must be met.

Responsible person. This is anyone with the duty and the authority to collect, account for, and pay over the taxes. Title doesn't decide it — control does. Owners and officers are obvious candidates, but so is a controller, an office manager, or a bookkeeper who signs checks, chooses which vendors get paid, or has authority over payroll. Because control can be shared, the IRS frequently names several people at once — each jointly and severally liable for the full amount.

Willfulness. This is the prong people misunderstand. Willful does not mean you set out to defraud anyone. It means you knew the taxes were due and, voluntarily and consciously, paid someone else first — employees, a landlord, a supplier. Keeping the doors open with money that should have gone to the IRS is willful, even when the motive was to save the company. Reckless disregard of a clear risk that the taxes weren't being paid also qualifies.

— The Form 4180 interview —

The IRS establishes both prongs largely through Form 4180 — a recorded interview asking who signed checks, who could hire and fire, who dealt with the IRS, and who decided which bills got paid. Answers given here routinely create the liability. Never sit for a 4180 interview without representation; what you say is the government's evidence.

How it gets assessed — and your 60 days

The IRS doesn't assess the TFRP silently. A revenue officer first investigates, then proposes the penalty with Letter 1153 and Form 2751, which lists the periods and amounts. From the date of that letter you generally have 60 days to file a written protest and take the case to IRS Appeals before the penalty is assessed. Missing that window forfeits the most favorable forum you have.

After assessment, options narrow but don't disappear: you can pay the tax for a single employee for one quarter and sue for refund to test responsibility in court, or pursue collection alternatives. Earlier is always better — the strongest move is a well-built protest inside the 60 days.

The defenses

  • Not a responsible person — you lacked real authority over which creditors were paid, even if your title suggested otherwise.
  • Not willful — you didn't know the taxes were unpaid, or the funds were encumbered (for example, a lender controlled the accounts) and genuinely beyond your control.
  • Wrong amount or periods — the trust-fund computation or the quarters at issue are incorrect.
  • Statute of limitations — the assessment window has closed.
  • Designated payments — directing available payments to the trust-fund portion first reduces personal exposure.

How this connects to the business 941 penalty

The TFRP runs alongside the company's own Form 941 failure-to-deposit penalty — two separate tracks for the same unpaid payroll taxes. The 941 penalties hit the business; the TFRP reaches the individuals behind it. Resolving payroll trouble means addressing both, and the order in which payments are designated affects personal liability. This is precisely the situation where getting the payroll and bookkeeping back under control — and the representation right — matters most.
