Trust Fund Recovery Penalty under IRC §6672: the responsible person and willfulness elements, the 100% trust-fund liability, the non-dischargeability in bankruptcy, and the Letter 1153 appeal process

If you own, operate, or hold a financial role in a business that failed to remit payroll taxes to the IRS, you may face personal liability for those taxes through the Trust Fund Recovery Penalty (TFRP) under IRC §6672(a). The TFRP is one of the most aggressive collection tools the IRS has, because it pierces the corporate veil and reaches individuals personally for what would otherwise be a corporate tax obligation.

The TFRP is not a penalty in the traditional sense of being an amount added to a tax deficiency. It is a collection device that permits the IRS to impose liability on a "responsible person" who "willfully" failed to remit the employment taxes that were held in trust for the government. The penalty is equal to 100% of the trust-fund portion of the unpaid employment taxes.

The substantial exposure, combined with the non-dischargeability in bankruptcy, makes the TFRP one of the most serious tax liabilities an individual can face. Understanding the two statutory elements (responsible person and willfulness), the defenses available, and the procedural framework is essential for anyone facing TFRP exposure.

What the TFRP reaches

Employment taxes consist of several components:

The employee's share of federal income tax (withheld from wages).

The employee's share of FICA (Social Security and Medicare) taxes (withheld from wages).

The employer's matching share of FICA taxes.

Federal unemployment tax (FUTA).

The TFRP reaches only the "trust fund" portion: the withheld income tax and the employee's share of FICA. These are the amounts the employer withholds from employee wages and holds "in trust" for the government before remitting them. The employer's matching FICA share and FUTA are not trust-fund taxes and are not reached by the TFRP.

The trust-fund characterization is the conceptual foundation. When an employer withholds taxes from an employee's paycheck, the employer is holding the government's money. The employee gets credit for the withheld taxes regardless of whether the employer remits them (the government has effectively paid the employee's tax liability and bears the loss if the employer doesn't remit). The TFRP allows the government to recover the trust-fund taxes from the responsible individuals when the corporate entity fails to remit.

The TFRP is equal to 100% of the unremitted trust-fund taxes. For a business that failed to remit $200,000 in employment taxes over several quarters, if $130,000 of that was trust-fund portion (withheld income plus employee FICA), the TFRP exposure is $130,000.

The two statutory elements

Per IRC §6672(a) and the case law, two elements must both be established before a person can be held liable for the TFRP:

The individual must be a "responsible person" for collecting, accounting for, and paying over the trust-fund taxes.

The person must have "willfully" failed to collect, account for, or pay over the taxes, or willfully attempted to evade or defeat the tax.

Both elements must be present. A person who is responsible but did not act willfully is not liable. A person who acted willfully but is not a responsible person is not liable. The IRS must establish both; once the IRS makes an assessment, the burden shifts to the taxpayer to disprove one or both elements.

Element 1: Responsible person

Responsibility is a function of duty, status, and authority. Per the IRS Internal Revenue Manual (IRM 8.25.1) and the case law, a "responsible person" is one who has significant (but not necessarily exclusive) control over the company's finances.

The factors considered in the responsible person analysis:

Whether the person is an officer or director of the corporation.

Whether the person owns stock in the corporation.

Whether the person has the authority to sign checks.

Whether the person has the authority to hire and fire employees.

Whether the person controls the company's financial affairs and decision-making.

Whether the person has the authority to determine which creditors get paid.

Whether the person signs tax returns or other financial documents.

No single factor is dispositive. The analysis is functional: does the person have significant control over the financial decisions, including the decision of whether to pay the trust-fund taxes?

The case law has refined the analysis:

Hornsby v. IRS established that title and signature authority alone do not establish responsibility. A person who has signature authority but does not exercise independent control over financial decisions may not be a responsible person.

Gephart v. United States established that subordinates without independent discretion may not be responsible persons. An employee who processes payroll under the direction of others, without the authority to make the payment-priority decisions, may not be liable.

The "dominant shareholder/officer" doctrine recognizes that when one person exercises complete control over the company's finances, subordinates may escape liability because they lacked the actual authority to redirect the trust-fund taxes.

Multiple responsible persons can be held jointly and severally liable. The IRS can pursue the full TFRP from any responsible person; the government doesn't apportion the liability. Responsible persons who pay can pursue contribution from other responsible persons under §6672(d), but that's a separate civil action against the co-responsible persons, not a reduction in the IRS's claim.

Element 2: Willfulness

Per the case law, willfulness under §6672 has been defined as a "voluntary, intentional, and conscious decision" to pay other creditors rather than remit the trust-fund taxes to the government (Godfrey).

Willfulness does not require malicious intent or an intent to defraud. It requires only that the responsible person:

Knew (or should have known) that the trust-fund taxes were due; AND

Either chose not to pay them, or recklessly disregarded an obvious risk that they would not be paid.

The courts have held that reckless disregard of the duty to collect and pay employment taxes satisfies the willfulness prong; mere negligence is never sufficient.

The operative scenarios:

Paying other creditors instead of the IRS. When a business has insufficient funds to pay all obligations, and the responsible person chooses to pay suppliers, employees' net wages, rent, or other creditors instead of the trust-fund taxes, that choice is willful. The government's position (supported by the case law, including Hochstein v. United States) is that an employee owed wages is merely another creditor, and preferences to employees over the government constitute willfulness.

Paying net wages when funds are insufficient for withholding. The payment of net wages to employees when funds are not available to pay the withholding taxes is a willful failure to collect and pay over. If funds are insufficient to cover both wages and withholding, the responsible person has a pro-rata duty: the available funds must be prorated between the government and the employees so that the taxes are fully paid on the amount of wages actually paid.

Failure to investigate or correct after notice. A responsible person's failure to investigate or correct mismanagement after being notified that withholding taxes have not been paid satisfies the willfulness requirement. Once a notice arrives and the responsible person does nothing, willfulness usually attaches from that day forward.

The limited willfulness defenses

Section 6672 has no statutory reasonable-cause exception, unlike many other IRS penalties. The fact that the responsible person had a good reason for the failure does not, in itself, defeat the willfulness element.

However, certain factual scenarios can negate willfulness:

Reliance on a payroll service (in limited circumstances). Reliance on a payroll service can negate willfulness, but only if the responsible person can show the service was actually being funded and the person had no reason to suspect deposits were being missed. If the payroll service was not being funded (because the business didn't have the money), reliance is not a defense.

Lack of knowledge during the relevant period. If the responsible person genuinely did not know about the delinquency and had no reason to know, willfulness may be absent for the period before they learned of it. This works in narrow scenarios: a senior lender that took over the bank account before the deposit deadline, a court-appointed receiver that controlled disbursements, or a verifiable date on which the responsible person first learned of the delinquency followed by immediate corrective action.

Embezzlement or fraud that hid the delinquency. When an employee committed embezzlement or fraud that hid the trust-fund delinquency from an otherwise diligent owner, Appeals Officers sometimes apply reasonable-cause-style reasoning under the willfulness umbrella. This is not a statutory exception but a practical recognition that the owner could not have known about a concealed delinquency.

The Warnement v. United States case (2025, Court of Federal Claims) illustrates the willfulness analysis. The court found that the taxpayer's awareness of the unpaid taxes was established by explicit warnings (an email outlining the trust-fund tax consequences and personal liability under §6672) and consistent reporting (monthly cash schedules showing the financial situation). The taxpayer's claim of not understanding the consequences was deemed unsupported, and the court found willfulness would be established as a matter of law if responsibility were established at trial.

The 100% liability and non-dischargeability

The TFRP is equal to 100% of the trust-fund portion of the unremitted taxes. There is no reduction for the employer's matching share (which is not trust-fund) or for partial payments unless those payments were specifically designated to the trust-fund portion.

The TFRP is not dischargeable in bankruptcy. Per Bankruptcy Code §523(a)(7) and the priority rules in §507(a)(8)(C), trust-fund recovery penalties survive personal bankruptcy intact.

A personal Chapter 7 bankruptcy does not discharge the TFRP.

A corporate Chapter 11 reorganization does not eliminate the TFRP, because the assessment runs against the responsible individuals, not the corporate entity.

The non-dischargeability is one of the most significant features of the TFRP. Most tax debts can be discharged in bankruptcy under specific conditions (the 3-year rule, the 2-year rule, the 240-day rule); the TFRP cannot. A responsible person facing TFRP liability cannot escape it through bankruptcy.

The designated payment strategy

Section 6672 liability follows trust-fund tax periods specifically. If the business still has assets and is making payments to the IRS, voluntary payments designated to the trust-fund portion of specific quarters can reduce or eliminate the personal exposure of the responsible persons.

The strategy: when the business makes a voluntary payment to the IRS, it can designate that the payment be applied to the trust-fund portion of a specific quarter. This reduces the trust-fund balance that could be assessed against the responsible persons. Payments that are not designated are applied by the IRS according to its own priorities (typically to the oldest periods or the non-trust-fund portions first), which may not reduce the responsible person's exposure.

The designated payment strategy requires the business to still have assets and to be making payments. For businesses that have already failed, the strategy is not available; the responsible persons face the full TFRP for the unremitted trust-fund taxes.

The procedural framework

The TFRP assessment process:

Step 1: Form 4180 interview. The IRS Revenue Officer conducts a Form 4180 interview ("Report of Interview with Individual Relative to Trust Fund Recovery Penalty") to determine who the responsible persons are and whether they acted willfully. The interview covers the person's role, authority, knowledge, and financial decision-making.

Step 2: Letter 1153 and Form 2751. If the IRS determines that a person is a responsible person who acted willfully, it issues Letter 1153 (the notice of proposed TFRP assessment) accompanied by Form 2751 (the proposed assessment showing the trust-fund amounts by quarter).

Step 3: 60-day appeal window. The taxpayer has 60 days from the Letter 1153 to file a protest with IRS Appeals. The Appeals process is the primary administrative avenue to contest the proposed assessment.

Step 4: Assessment. If the taxpayer does not protest, or if Appeals upholds the assessment, the IRS assesses the TFRP against the responsible person. Once assessed, the burden shifts to the taxpayer to disprove the elements in any subsequent litigation.

Step 5: Collection or refund litigation. After assessment, the responsible person can either pay and sue for refund (paying the divisible tax for one employee for one quarter, then suing for refund and challenging the entire assessment) or contest the assessment through collection due process. The refund-suit route allows litigation in federal district court or the Court of Federal Claims (not Tax Court, since the TFRP is not within the Tax Court's deficiency jurisdiction).

The divisible tax litigation strategy

The TFRP is a "divisible tax," meaning it can be broken into separate amounts for each employee for each quarter. This creates a litigation strategy: rather than paying the entire TFRP to sue for refund, the responsible person can pay the trust-fund tax for a single employee for a single quarter (a small amount), file a refund claim, and then sue for refund. The refund suit allows the responsible person to challenge the entire TFRP assessment without paying the full amount upfront.

The divisible-tax strategy is the standard route for litigating TFRP liability. The full assessment is at stake in the refund suit even though only a small amount was paid; if the responsible person prevails on the responsibility or willfulness elements, the entire assessment is abated.

Coordination with other tax-debt provisions

The TFRP operates in coordination with several other Halstonberg tax-debt provisions:

Currently Not Collectible status can apply to TFRP liability for responsible persons who cannot afford to pay.

Offer in compromise is available for TFRP liability, with the standard reasonable collection potential analysis. The TFRP can be compromised even though it cannot be discharged in bankruptcy.

Collection due process procedures apply to TFRP collection in the same way as other federal tax collections.

§7345 passport revocation can apply to seriously delinquent TFRP liability.

§6651 failure-to-file and failure-to-pay penalties apply to the underlying corporate employment tax returns, separate from the TFRP that reaches the responsible persons.

Practical guidance

For business owners and financial officers concerned about TFRP exposure:

The trust-fund taxes must be paid first. When cash is tight, the temptation to pay suppliers, employees, or other creditors before the IRS is the precise scenario that creates willful TFRP liability. The trust-fund taxes are the government's money; paying other creditors instead is willful.

If the business is struggling, prioritize the trust-fund tax deposits. If you cannot pay all obligations, the pro-rata duty requires you to remit the trust-fund taxes on the wages actually paid. Paying net wages without remitting the corresponding withholding is willful.

Document your role and authority accurately. If you are not actually a responsible person (you lack the authority to determine which creditors get paid), document the limits of your role. The Hornsby and Gephart cases establish that title and signature authority alone don't make you responsible.

Respond to the Letter 1153 within 60 days. The 60-day appeal window is the primary administrative avenue to contest the proposed assessment. Missing the deadline forfeits the Appeals opportunity (though the refund-suit route remains available after assessment).

For the Form 4180 interview, consider representation. The interview is the IRS's primary tool for establishing the responsibility and willfulness elements. What you say in the interview can be used to support the assessment; counsel familiar with the TFRP framework can help you navigate the interview.

If the business still has assets, use the designated payment strategy. Designating voluntary payments to the trust-fund portion of specific quarters reduces the personal exposure of the responsible persons.

Understand that bankruptcy will not help. The TFRP is non-dischargeable; personal Chapter 7 will not eliminate it. Plan accordingly; the liability will persist through bankruptcy.

For litigation, the divisible-tax refund strategy allows challenging the full assessment without paying it all upfront. Paying the tax for one employee for one quarter, then suing for refund, is the standard route.

The TFRP is among the most serious individual tax liabilities. The 100% trust-fund liability, the joint and several liability among responsible persons, the lack of a reasonable-cause exception, and the non-dischargeability in bankruptcy combine to make it a substantial exposure. Business owners and financial officers should treat trust-fund tax compliance as a first-priority obligation; the personal consequences of failure are severe and persistent.
