The Trust Fund Recovery Penalty: Why Payroll Tax Debt Follows You Home

You closed the corporation, so the payroll tax debt died with it. That is the belief almost everyone walks in with, and it is a reasonable one. The whole point of an LLC or an S-corp is that the business is a separate legal person: its debts are its own, and when it fails, creditors get what is left in the bank and nothing more from you.

That logic holds for the landlord, the supplier, and the bank. It does not hold for the IRS on one specific slice of the payroll tax.

The Trust Fund Recovery Penalty, authorized by §6672, reaches through the corporate shield and lands on you personally. Dissolving the entity does not extinguish it. Bankruptcy usually does not discharge it. And it is not really a "penalty" in the ordinary sense, despite the name. It is the government collecting money it considers to have been stolen from it, and it will collect that money from whoever had their hands on the checkbook.

What is the Trust Fund Recovery Penalty?

The Trust Fund Recovery Penalty is the IRS assessing unpaid payroll taxes against an individual personally under §6672, equal to the "trust fund" portion of what the business withheld from employees but never remitted.

Here is why the word "trust" is doing real work. When you run payroll, you withhold your employee's income tax and their half of Social Security and Medicare (FICA) from their gross pay. That money was never yours. The moment it leaves the employee's paycheck, you are holding it in trust for the United States under §7501, which literally titles those amounts a "special fund in trust." You are a custodian, not an owner.

So when the business is short on cash and you pay the electric bill instead of the tax deposit, the IRS's view is not "you failed to pay a debt." It is "you took money that belonged to the Treasury and spent it on something else." That framing is why the liability is personal and why the collection posture is so aggressive.

The trust fund portion is only part of a payroll tax bill. A quarter's Form 941 liability breaks into two pieces:

• The trust fund portion: the income tax and employee-side FICA withheld from paychecks. This is what §6672 lets the IRS pursue personally.
• The non-trust-fund portion: the employer's matching half of FICA, plus any penalties and interest. This stays with the entity and does not transfer to individuals.

For a rough sense of scale, on wages the employee FICA share is 7.65 percent (6.2 percent Social Security up to the wage base, 1.45 percent Medicare with no cap), and that sits on top of the withheld federal income tax. Add it up across a few unpaid quarters and the trust fund number gets large fast.

Who can the IRS come after personally?

Anyone the IRS decides was both a "responsible person" and acted "willfully" under §6672. That is a wider net than most people expect, and it is not limited to the owner.

A responsible person is someone with the authority and duty to collect, account for, and pay over the withheld taxes. The IRS looks at function, not job title. Signs that point at you include:

• Check-signing authority on the business bank account
• Authority to decide which creditors get paid and when
• The power to hire and fire, or to sign tax returns
• Control over payroll or the general ledger

"Willful" is the part people misread. It does not mean you had an evil motive or personally pocketed the cash. Under the case law interpreting §6672, willfulness means you knew the taxes were owed and you paid someone else first. A voluntary, conscious, intentional decision to pay a net paycheck, a landlord, or a key vendor while the deposit went unpaid is willful. "I was trying to keep the doors open" is not a defense. It is, in the IRS's eyes, the confession.

That is how a bookkeeper, a controller, or a minority partner with signature authority ends up assessed alongside the owner. The IRS can name multiple responsible persons, and each is liable for the full trust fund amount, not a pro-rata slice. They collect once, but they can chase everyone until they do.

The moment the misconception got expensive

A client of mine ran a fifteen-person HVAC company, S-corp, and had run it well for a decade. When a big commercial customer stretched payment out past 120 days, the cash crunch hit exactly where cash crunches always hit: the tax deposits. He kept making payroll, kept the trucks fueled, kept the crews working, and told himself he would catch up the 941 deposits when the receivable landed. Three quarters slipped. The receivable came in smaller than expected. The company folded.

He assumed that was the end of it. The corporation was gone; the debt was the corporation's.

Then a revenue officer scheduled a §6672 interview and worked through Form 4180, the questionnaire the IRS uses to establish responsibility and willfulness. His own honest answers built the case: yes, he signed the checks; yes, he chose which bills to pay; yes, he knew the deposits were behind. The trust fund portion assessed against him personally was just under $140,000. His office manager, who also had check-signing authority, got a Letter 1153 proposing to assess her too, and we had to fight to show she paid only what he directed and had no authority to choose creditors.

He walked in believing he owed nothing. He walked out with a six-figure personal liability that no dissolution and no bankruptcy filing was going to erase.

Can you discharge the Trust Fund Recovery Penalty in bankruptcy?

Almost never. The trust fund portion is treated as a non-dischargeable priority tax under the Bankruptcy Code, so filing personal bankruptcy typically leaves the §6672 assessment standing after everything else is wiped.

This surprises people who assume bankruptcy is a clean reset. It resets a lot of things. It generally does not reset money you were holding in trust for the government. The debt survives, the interest keeps running, and the IRS can levy your wages and bank accounts and file a Notice of Federal Tax Lien against you as an individual once the penalty is assessed.

There is a narrow timing window worth knowing. The IRS generally must assess a §6672 penalty within the normal assessment period, and it must first send you Letter 1153 with a Form 2751, giving you 60 days to file a protest before the assessment becomes final. That 60-day window is the cheapest point at which to fight, because once it is assessed, you are litigating a collection matter instead of a proposed liability.

What do you actually do about it?

You engage early, ideally before the Form 4180 interview, and you build the record on responsibility and willfulness rather than answering off the cuff. The interview is where liability is decided, and its questions are not neutral.

A few things shape how these cases resolve:

1. Contest the "responsible person" finding where the facts support it. A titular officer with no check authority, or an employee who paid only what an owner directed, may not be a responsible person. That is a fact fight, and Form 4180 answers are the ammunition on both sides.
2. Attack willfulness for the specific quarters. If you genuinely did not know deposits were missed, or funds were encumbered and beyond your control, that quarter may fall out.
3. Have the company pay the trust fund first, if it can. Under Rev. Rul. 79-284, a business making voluntary payments can designate them to the trust fund portion, shrinking the amount that can ever land on you personally. Involuntary payments (levies) get applied as the IRS sees fit, so designation only works while you are paying voluntarily.
4. Once assessed, run the collection alternatives. An installment agreement, an offer in compromise based on doubt as to collectibility, or currently-not-collectible status under the §6330 collection due process framework are all on the table, same as any other tax debt. If a lien or levy notice arrives, you have appeal rights under §6320 and §6330 that are worth using.

If you are still operating and behind on 941 deposits, the single highest-value move is to stop the bleeding on the current quarter first. The IRS is far more workable on old trust fund debt when you are current going forward. Get the next deposit made on time, then deal with the back quarters.

And if you share a checkbook with a business that is behind on payroll taxes, understand that you may already be exposed, whatever your title says. This is the point where a conversation with a representative and, where ownership disputes or bankruptcy are in play, your attorney, is worth far more than it costs.
