When payroll taxes go unpaid, many business owners assume the problem stays with the company. In Trust Fund Recovery Penalty cases, that assumption can unravel fast.
The Trust Fund Recovery Penalty, often called the TFRP, allows the IRS to pursue certain individuals personally for the trust fund portion of unpaid employment taxes under Internal Revenue Code § 6672. In general terms, that means withheld federal income taxes and employees’ share of Social Security and Medicare taxes can become a personal issue for people the IRS views as both responsible and willful in the nonpayment. The IRS lays out those two core elements in its Internal Revenue Manual, explaining that responsibility turns on “status, duty, and authority,” while willfulness often centers on knowingly paying other creditors after learning payroll taxes are not being paid to the government (IRS IRM 5.7.3).
If you’re new to this area, it may help to start with this broader overview of how TFRP liability works and why responsible-person exposure matters. In this post, you’ll learn about seven common mistakes that can increase personal exposure once a payroll tax problem is already in motion.

Why TFRP Cases Feel More Personal Than Other Tax Debts
A TFRP case is not just about a delinquent business return. It is an IRS effort to identify real people connected to the company who had enough control over financial decisions to be held personally liable. According to the IRS, more than one person can be responsible, and each responsible person can be assessed for the full unpaid trust fund amount (IRS IRM 5.19.14; IRS Chief Counsel guidance).
That is where exposure often increases. A person may have assumed they were “just helping,” “just signing checks,” or “just filling in temporarily.” But the IRS does not stop at job titles. It looks at practical control: check-signing authority, power over payroll, authority to decide which bills get paid, involvement in tax filings, hiring and firing authority, and the ability to direct business finances (IRS IRM 5.7.3).
Mistake #1: Assuming The LLC Or Corporation Shields You Automatically
One of the most common TFRP mistakes is treating unpaid payroll taxes like ordinary business debt.
For many liabilities, the entity structure matters a lot. For trust fund taxes, the IRS has a separate collection tool aimed at individuals. Section 6672 imposes personal liability on any person required to collect, account for, and pay over the tax who willfully fails to do so (Cornell LII). The IRS describes the TFRP as applying when a business fails to collect or pay trust fund taxes and the unpaid liability is assessed against responsible business individuals (IRS IRM 5.19.14).
Here’s what this often means in practice: even if the company is struggling, dissolved, insolvent, or headed toward bankruptcy, the IRS may still investigate owners, officers, managers, payroll personnel, and other decision-makers individually. Some people in similar situations are surprised to learn that “limited liability” does not automatically end the discussion when withheld payroll taxes are involved.
Mistake #2: Thinking A Title Alone Controls The Outcome
Another exposure-increasing mistake is relying too heavily on formal titles.
People sometimes assume the opposite things for the same reason:
“I’m the CFO, so I’m automatically liable.”
“I’m only a manager/bookkeeper/member, so I’m automatically safe.”
The IRS approach is more fact-specific than either of those assumptions. Its own manual states that responsibility is a matter of status, duty, and authority, and that a person can have significant control even without final word over every financial decision (IRS IRM 5.7.3). The same manual also notes that a non-owner employee who performs purely ministerial acts under someone else’s control will generally not be treated as responsible. On the other hand, a non-owner with meaningful financial decision-making power still may face exposure (IRS IRM 5.7.3).
Mistake #3: Continuing To Pay Vendors After Learning Payroll Taxes Are Behind
This is often the most dangerous fact pattern in a TFRP case.
The IRS manual says willfulness can be established when a responsible person knows the taxes are due and uses available funds to pay other creditors instead of the government (IRS IRM 5.7.3). Taxpayer Advocate materials discussing the statute similarly describe willfulness as making a deliberate choice to pay other creditors with knowledge that trust fund taxes are unpaid (Taxpayer Advocate Service).
This is where many people unintentionally make the record worse. They are trying to keep the business alive. They pay rent, utilities, key suppliers, insurance, or net payroll to employees, hoping they can “catch up” with the IRS later. From a business survival perspective, that may feel rational. From a TFRP perspective, it can become evidence the IRS points to when arguing willfulness.
The risk often increases once a person has actual knowledge of the tax problem. After that point, every later disbursement may receive extra scrutiny. If you’re dealing with an investigation already, it may help to review which facts often end up mattering most in responsible-person disputes.
Mistake #4: Treating The Form 4180 Interview Like A Casual Conversation
The IRS uses Form 4180, “Report of Interview with Individual Relative to Trust Fund Recovery Penalty or Personal Liability for Excise Taxes,” to gather information relevant to responsibility and willfulness (IRS IRM 11.3.40; IRS IRM 5.7.4). That interview is not small talk. It is one of the central fact-development stages in many TFRP cases.
A lot of exposure can build here because people:
speculate instead of sticking to what they know,
overstate or understate their authority,
accept loaded characterizations,
forget dates and timelines,
blur together what they personally did versus what others directed,
bring incomplete records,
or try to appear cooperative by agreeing with broad statements that later look admissions.
In general terms, TFRP cases often turn on details: who signed checks, who decided what got paid first, who saw the delinquency notices, who spoke with the payroll provider, who had online banking access, who could hire or fire, and when each person learned taxes were not being deposited.
Mistake #5: Ignoring Letter 1153 Or Missing The Response Window
Once the IRS proposes assessing the TFRP against an individual, it generally sends Letter 1153 along with Form 2751. The IRS manuals explain that the person has 60 days from the mailing date or personal delivery date to respond, or 75 days if the letter was addressed outside the United States (IRS IRM 5.7.6; IRS IRM 11.3.40).
That timeline matters.
People sometimes leave the letter unopened because they believe the company’s CPA is handling it, because the business closed years ago, or because they assume the IRS sent the same notice to everyone and it may not really apply to them. In many cases, that is where exposure grows. Once the deadline passes, the proposed assessment can move forward and the conversation shifts from preventing an assessment to dealing with an assessed personal liability.
An attorney or tax controversy professional may help evaluate whether the proposed assessment can be challenged on responsibility, willfulness, procedure, or evidence. In some cases, the record may already contain weaknesses the IRS has not fully resolved. In others, the real issue may be preserving rights before the file moves deeper into collection.
Mistake #6: Believing The IRS Can Only Pursue One Person
TFRP investigations often involve several people at once, and this surprises a lot of businesses.
The IRS can investigate multiple potentially responsible persons and assess more than one individual for the same trust fund taxes. Its manual specifically refers to securing Form 4180 interviews from all potentially responsible persons to the extent possible and reviewing all documentation to determine responsibility and willfulness for each one (IRS IRM 5.7.4). IRS guidance and Chief Counsel materials also reflect that each responsible person may be severally liable for the full unpaid trust fund amount, even though the government can collect the liability only once overall (IRS IRM 5.19.14; IRS Chief Counsel guidance).
That creates a common strategic problem: one person assumes someone else is the real target, so they delay getting advice, delay gathering records, or fail to correct inaccurate narratives early. Meanwhile, another executive, owner, office manager, or payroll employee may be giving statements that reshape how the IRS sees everyone’s role.
Where multiple insiders had overlapping authority, individual interests may not line up as neatly as people expect.
Mistake #7: Waiting Until Collection Starts Before Taking Personal Risk Seriously
Some people do not focus on the TFRP until after the IRS has already assessed the penalty and collection notices begin arriving. By then, the conversation may include liens, levies, appeals, collection alternatives, and asset exposure.
The IRS explains in its general collection guidance that it may use liens and levies to collect unpaid federal tax liabilities, and that taxpayers have rights during the process, including appeal rights described in Publication 1660 and the broader collection framework in Publication 594 (IRS Topic No. 201; IRS Publication 594). The Taxpayer Advocate Service also notes that a timely Collection Due Process request can preserve administrative review and, in some situations, court review, while an untimely request may reduce those options to an equivalent hearing without the same judicial path (Taxpayer Advocate Service).
Here’s what this often means: the earlier stage of a TFRP case is usually about whether the IRS can assess you at all. The later stage is often about how the IRS will collect. Those are very different positions.
Once assessment happens, the practical pressure on the individual usually increases. That is why experienced representation is often less about making dramatic arguments at the last second and more about building the record before key deadlines pass.
Why These Mistakes Increase Exposure So Quickly
All seven mistakes share one theme: they make it easier for the IRS to argue one or both of the statutory elements.
To assess the TFRP, the IRS is looking for evidence that a person:
had enough authority or control to qualify as responsible, and
knowingly failed to remit trust fund taxes, or paid others instead, in a way the IRS can characterize as willful (IRS IRM 5.7.3).
That is why even seemingly small facts can matter:
access to business bank accounts,
email involvement in payment decisions,
payroll platform credentials,
knowledge of bounced payroll tax deposits,
signed Forms 941,
authority to hire a replacement payroll company,
discussions with lenders,
or approval of payments to insiders and vendors after taxes were already behind.
Some people have very limited involvement and may have strong factual distinctions. Others have mixed facts that require careful framing. Either way, the analysis is usually more nuanced than “owner equals liable” or “employee equals safe.”
A Better Way To Think About TFRP Risk
If there is one practical takeaway, it is this: TFRP exposure is usually a fact-and-timeline problem, not just a paperwork problem.
The strongest defenses in these cases often revolve around documented limits on authority, lack of independent decision-making, unclear or delayed knowledge, reliance on others in ways that did not amount to control, procedural flaws, or factual disputes over who actually decided to pay which creditors and when. The IRS itself recognizes that ministerial employees acting under another person’s dominion and control generally are not the intended target of the penalty (IRS IRM 5.7.3).
That said, these cases can move quickly once the IRS starts interviewing people and issuing notices. Business owners, officers, and financial staff often benefit from counsel who understands both the legal standards and the factual patterns that tend to appear in payroll tax investigations.
Final Thoughts
TFRP cases often become personal because the IRS is not just asking whether a company failed to pay payroll taxes. It is asking who knew, who controlled, who decided, and what happened after the problem became known.
The seven mistakes above—trusting the entity shield, overrelying on titles, paying other creditors first, mishandling the Form 4180 interview, ignoring Letter 1153, assuming only one person is at risk, and waiting until collection begins—can all increase personal exposure in different ways.
