Trust Fund Recovery Penalty: IRC § 6672 and Personal Liability for Payroll Taxes

What Is the Trust Fund Recovery Penalty?

The trust fund recovery penalty (TFRP) is a 100% personal liability assessment under IRC § 6672 imposed on individuals who were responsible for — and willfully failed to remit — the employee portion of federal employment taxes.

When a business pays employees, it withholds two categories of taxes from each paycheck: federal income tax withholding and the employee's share of FICA (Social Security and Medicare). Those withheld amounts don't belong to the company. The IRS treats them as funds held in trust on behalf of the employees — hence "trust fund taxes." The business is required to remit them to the IRS, along with the employer's matching FICA share, through periodic payroll tax deposits.

When a business fails to make those deposits — usually because it's running out of cash and paying other creditors first — the IRS uses IRC § 6672 to reach the individuals who had the authority to see that the taxes were paid. The penalty is 100% of the unpaid trust fund portion. On a $200,000 payroll tax liability, the trust fund component might be $120,000, and the IRS can assess that full $120,000 personally against each person it identifies as responsible.

Two things worth noting at the outset. First, the TFRP only covers the trust fund portion — the employee withholding and the employee FICA share. It does not cover the employer's matching FICA contribution or FUTA. Second, it is a civil penalty, not a criminal charge, though the conduct that triggers it can also support criminal liability under separate statutes.

Which Taxes Are "Trust Fund" Taxes?

When the IRS calculates how much to assess as a TFRP, it allocates each payroll tax payment made by the business to the non-trust-fund portion first. This is not favorable to the taxpayer — it means the trust fund balance stays unpaid longer, and the TFRP exposure grows.

Who Is a "Responsible Person" for Payroll Taxes?

The IRS and the courts have defined "responsible person" broadly over decades of litigation. The short version: if you had the ability to direct which company creditors got paid, you are a candidate for the TFRP. People the IRS has successfully assessed include:

• Business owners and sole proprietors
• Corporate officers (CEO, CFO, COO, president, vice president, treasurer)
• Directors who had actual financial control
• Bookkeepers and office managers with check-signing authority
• Investors or passive shareholders who were actively involved in financial decisions
• Successors who took control of a business with existing payroll tax debt

Being an officer does not automatically make you a responsible person. And not being an officer does not protect you. The question is whether you had the authority to ensure the taxes were paid and chose not to — or whether you should have known they weren't being paid and took no action.

In practice, the IRS assesses the TFRP broadly and lets the courts sort it out. Multiple people within the same organization are commonly assessed the full penalty simultaneously. That matters because the person most financially exposed often ends up paying a disproportionate share.

The Willfulness Element: What It Actually Means

This is where most TFRP cases actually turn. Business owners facing cash flow problems often prioritize keeping the business alive — paying employees their net wages, keeping suppliers current, making rent — while letting payroll tax deposits slip. From their perspective, this is pragmatic. From the IRS's perspective, it is willfulness.

The controlling standard from the courts: willfulness is reckless disregard of a known risk of nonpayment. You don't have to have signed a check marked "I intend to defraud the IRS." If you knew the taxes weren't being remitted and you authorized payments to other creditors anyway, courts have found that sufficient. Godfrey v. United States, Monday v. United States, and decades of circuit court decisions follow this pattern consistently.

Two factual scenarios that complicate the willfulness analysis:

• Delegating payroll to a third party. If you gave a bookkeeper or payroll processor the responsibility for remitting taxes and they didn't do it, courts have still found willfulness where the owner had the authority to ensure payment and failed to follow up. Delegation is not a complete defense.
• Genuine financial impossibility. In very limited circumstances — where the business had no available funds and no ability to obtain them — courts have declined to find willfulness. This is a narrow exception and the IRS litigates it aggressively. The absence of funds must be total and not the result of a choice to pay others first.

The IRS Investigation: Form 4180 and What Happens Before the Assessment

When payroll taxes go unpaid, the IRS assigns a revenue officer to investigate. The revenue officer's job is to identify every potentially responsible person within the organization and assess the TFRP against each of them. The tool they use is the Form 4180 interview.

Form 4180 asks a series of structured questions covering:

• Your title and your actual duties at the company
• Who signed payroll checks and accounts-payable checks
• Whether you had signatory authority on bank accounts
• Whether you could hire and fire employees
• Whether you were involved in financial decisions, including which creditors to pay
• When you first learned that payroll taxes were not being remitted
• What you did — or didn't do — after learning that

You have the right to have an attorney present during a Form 4180 interview. This is not a right you should waive. The interview is not informal. It is a fact-gathering process conducted by someone whose job is to build the IRS's case. Answers that seem innocuous — "I signed checks when the controller was out" — can establish responsible person status. Answers that seem helpful — "I tried to get the owner to pay the taxes but couldn't" — can simultaneously establish willfulness.

We prepare clients for Form 4180 interviews as a matter of course. The preparation covers not just what to say but what not to say, and which facts actually matter legally versus which ones the revenue officer is asking about for other reasons.

Multiple Responsible Persons: Joint and Several Liability

If three people in an organization are each assessed a $150,000 TFRP, the IRS can collect up to $150,000 total across all three — but it can pursue any one of them for the full amount. The IRS typically starts collection against the person most able to pay.

If one responsible person pays a portion of the penalty, that payment reduces the liability of all assessed persons by that amount. This creates an unusual dynamic: if you are a co-responsible person and someone else pays down the TFRP, your exposure decreases even though you didn't pay anything. It also creates the opposite dynamic: if you are the most solvent person in the group, you may end up bearing the full cost of a failure that others participated in equally.

Co-responsible persons can bring civil contribution claims against each other. This is not an IRS matter — it's a separate civil action — but it's a real consideration when deciding how to handle a TFRP assessment.

The Assessment Process: Form 2751 and the 60-Day Protest Window

The sequence typically runs:

1. Revenue officer conducts Form 4180 interviews and gathers financial records
2. Revenue officer prepares a summary identifying responsible persons and recommending the penalty amount
3. IRS issues Form 2751 to each identified responsible person — this is the proposed assessment
4. 60-day protest period begins from the date on Form 2751
5. If no protest is filed, the assessment becomes final and the IRS begins collection
6. If a protest is filed, the case goes to IRS Office of Appeals for independent review

The 60-day window is the single most important deadline in a TFRP case. Missing it does not mean you lose the ability to contest the penalty entirely — you can still pay a divisible portion and sue for refund in federal district court or the Court of Federal Claims — but it eliminates the cheaper and faster administrative appeal path.

A written protest to IRS Appeals is not a simple form. It needs to address the responsible person analysis, the willfulness element, and any factual disputes about what you actually did and when. Generically drafted protests don't perform well at Appeals. The argument needs to be specific, grounded in the record, and tailored to which element — responsibility or willfulness — is actually in dispute.

Defenses to the Trust Fund Recovery Penalty

Defense 1: You Were Not a Responsible Person

To establish that you were not a responsible person, you need to show that you lacked the authority to direct the payment of corporate funds — that someone else controlled the checkbook and financial decisions, and your role was purely operational or advisory. This defense is available but requires more than saying "someone else was in charge." The evidence needs to show that in practice, you had no ability to ensure taxes got paid even if you wanted to.

Relevant facts include: who had signatory authority on bank accounts, who prepared or authorized checks, who made the actual decision about which bills to pay, and whether you were consulted on financial matters. If the answer to all of those is someone else — with supporting documentation — the responsible person argument has real legs.

Defense 2: You Did Not Act Willfully

This defense focuses on either knowledge or control. If you genuinely did not know that payroll taxes were going unpaid — because you reasonably relied on someone else and had no red flags — willfulness may be absent. This defense works best when you can show affirmative steps you took to ensure compliance, not just an absence of involvement.

The "no available funds" defense — that the company had no money and you couldn't have paid the taxes even if you tried — is the narrowest version of the willfulness defense. Courts look skeptically at this argument when the business was paying any other creditor during the delinquency period. If rent got paid and vendors got paid and employees got their net wages, the IRS's position is that the money was there and you chose where it went.

Deposit Allocation Arguments

A less common but sometimes valuable defense involves how the IRS allocated partial payments made by the business. Under IRS procedure, voluntary deposits are applied to the non-trust-fund portion of the employment tax liability first. But if the business designated specific payments to the trust fund portion, those designations may reduce the TFRP base. Reviewing the allocation history is worth doing in any case where the company made partial payments over an extended delinquency period.

California's Parallel Responsible Person Liability

The California Employment Development Department investigates payroll tax delinquencies independently of the IRS. An EDD audit can follow an IRS TFRP case, or it can precede one, or it can run in parallel. The two agencies share information but operate under separate legal frameworks.

The California standard tracks the federal one closely: willful failure by a person with authority to ensure payment. The EDD conducts its own responsible person interviews and can assess personal liability against the same people the IRS targeted — or different ones.

One practical difference: California's assessment and collection procedures are in some ways more aggressive than the IRS's. The EDD can record a lien against personal property relatively quickly, and the administrative appeal process at the California Office of Tax Appeals (OTA) is a different forum with different dynamics than IRS Appeals.

If you are facing a federal TFRP assessment, it is worth checking whether the EDD has or is likely to assert parallel liability. Handling both at the same time, with a coordinated strategy, is generally better than resolving the federal case and then dealing with California separately.

How Brotman Law Approaches TFRP Defense

The short version is that we get involved as early as possible — ideally before the Form 4180 interview, not after Form 2751 arrives.

Early involvement lets us shape the factual record before it hardens. By the time a client receives Form 2751, the revenue officer has already built a file. The interview transcript exists. The financial records have been reviewed. Contesting the assessment at Appeals becomes a matter of arguing about a record that was created without our input. That's a harder position to work from.

When we're retained before the Form 4180 interview, we can prepare the client on what questions to expect, what the legally relevant facts actually are (versus what feels important but isn't), and how to present their role in the organization accurately without volunteering information that extends liability. We can also assess early whether there's a credible responsible person or willfulness defense, which shapes how we approach the investigation.

If a client comes to us after receiving Form 2751, the first thing we do is evaluate the record and identify the strongest arguments for the protest. If the case goes to Appeals, we represent clients in those proceedings. If Appeals sustains the assessment and the client wants to litigate, we can evaluate the district court or Court of Federal Claims options.

We also handle cases where a client is the one paying the TFRP and wants to understand their options for contribution claims against co-responsible persons — that's a separate civil matter but one we can coordinate alongside the IRS defense.

If you've received Form 2751 or Form 4180, or if you're aware that a payroll tax delinquency exists at your company and you want to understand your personal exposure, book a call. We can usually give you a clear picture of where things stand in 15 minutes.
