The trust fund recovery penalty converts a business's unpaid payroll withholding into the personal, bankruptcy-proof debt of every responsible person who willfully failed to pay it over. The defense has a sequence, and its most important window opens earlier than anyone expects.
Fight the Elements
Responsibility is power, not title: the effective ability to decide which creditors got paid - banking control, check-signing actually exercised, authority over the people who handled payments. The wrongly-swept defend here: the order-following bookkeeper, the spouse on the signature card, the titled officer with no operational role, each shown through documents and consistent testimony about who actually overrode whom. Willfulness needs no malice - knowing the taxes were unpaid and paying anyone else suffices - so the genuine willfulness defenses are temporal: liability generally attaches from when you knew or recklessly ignored the delinquency, and the timeline of discovery becomes the case.
Control the 4180 Interview
The revenue officer's central evidence event is the Form 4180 interview - scripted, conversational in feel, evidentiary in function. The traps that assess unprepared people: overstated authority, guessed dates that move the willfulness timeline by quarters, and the volunteered sentence about deciding which creditors to pay. The countermoves: nobody sits unprepared, counsel attends or substitutes a written submission addressing the elements, answers stay bounded to actual knowledge, and 'I would need to check the records' gets used as the complete sentence it is.
Protest the 1153 - and Shrink the Exposure Meanwhile
Candidates the officer concludes against receive Letter 1153, opening 60 days to protest to Appeals - where these cases actually get won: responsibility narrowed to who truly held power, willfulness contested on the knowledge timeline, the computation itself corrected. Silence converts the proposal into an assessment with the full collection arsenal behind it. And the parallel move runs from day one: voluntary business payments designated in writing to the trust fund portion shrink what can ever be assessed personally, dollar for dollar - a rule almost nobody knows. If a 4180 request or an 1153 has your name on it, the windows are open now and they close on schedule. Call me first.
