The trust fund recovery penalty converts a business's unpaid payroll withholding into personal debt - assessable against owners, officers, and anyone else the IRS decides was responsible and willful. It survives the business, survives bankruptcy, and follows people for a decade. It is also more defensible than its reputation suggests, because both of its elements are fact questions, and facts can be fought.

The Responsibility Fight

Responsibility means actual authority over the money: who could sign checks, who decided which creditors got paid, who controlled the financial life of the business. Titles are evidence, not answers - the test reaches function. The officer who held a title while someone else controlled every dollar has a defense; the bookkeeper who merely executed instructions has a defense; the outside investor with no operational role has a defense. The case is built from bank signature cards, check registers, meeting minutes, and testimony about who really decided things, quarter by quarter, because authority can change over time and the penalty attaches only to quarters where it existed.

The Willfulness Fight

Willfulness does not require malice - paying any creditor while knowing the withholding was unpaid satisfies it. That makes the fight about knowledge and timing: when did this person actually learn the deposits were missed? Funds paid out before knowledge are not willful. A responsible person who discovered the problem and directed available money toward the trust fund afterward has a position. The reconstruction of who knew what, when, is detailed work, and it is where these cases are won.

The Procedural Battlefield

Defense has stations. The Form 4180 interview is the first and most dangerous - a scripted interrogation designed to establish both elements from your own answers, and nobody should sit for one unprepared or unrepresented. The proposed assessment letter opens a 60-day appeal window where these cases regularly resolve. After assessment, collection defenses still apply, and one structural feature helps: the IRS can assess multiple people for the same trust fund debt but collect it only once, so payments from the business or co-assessed persons reduce your exposure dollar for dollar.

If a revenue officer is asking about your role at a business with payroll debt, the defense starts before your first answer. Call me first.
