Overview
Payroll taxes (federal income tax withheld, Social Security and Medicare taxes) are treated as trust fund taxes: employers collect them from employees and hold them in trust for the government. When the IRS or a state tax agency suspects willful misconduct — not merely error — they may open a payroll tax criminal investigation. The IRS Criminal Investigation (IRS‑CI) unit handles these cases; criminal investigations differ from civil audits because prosecutors must prove willfulness and intent to evade. (See IRS Criminal Investigation.)
In my practice advising employers for over 15 years, the most common patterns that escalate civil issues into criminal probes are repeated failures to deposit trust fund taxes, clear efforts to hide payroll records, and using company funds for owner benefit while payroll liabilities go unpaid.

What commonly triggers a criminal investigation?
Investigations are fact‑driven, but the IRS looks for red flags that suggest willful behavior rather than negligence. Common triggers include:
- Repeated failure to make required payroll tax deposits or file Forms 941/940 on time despite notices.
- Significant unpaid trust fund balances (withheld income tax and employee FICA) that are used by owners for other business or personal expenses.
- Altered, missing, or inconsistent payroll records — e.g., paycheck stubs that don’t match bank disbursements or third‑party reports.
- Misclassification of employees as independent contractors, especially when coupled with other noncompliance.
- Filing false Forms 941/940 or W‑2s, or falsified payroll journals.
- Third‑party complaints, whistleblower tips, or information from former employees.
- Industry and cash‑intensive operations (restaurants, construction, staffing) with a history of payroll underreporting.
- Evidence of transferring funds out of the business to avoid IRS collection (dissipation of assets).
The IRS also monitors patterns across cases — repeat offenders or companies that repeatedly ignore notices are more likely to see enforcement escalate from civil collection to criminal inquiry.
How a criminal investigation differs from a civil audit or collection case
- Purpose: Civil audits aim to assess and collect unpaid taxes and penalties. Criminal investigations seek evidence of willful criminal conduct and can lead to prosecution.
- Standard of proof: Civil cases are decided on a preponderance of evidence; criminal prosecutions require proof beyond a reasonable doubt plus proof of willfulness/intent.
- Agency involvement: IRS‑CI investigates; if IRS‑CI finds criminal evidence they refer to the Department of Justice (DOJ) for prosecution.
- Potential outcomes: Civil resolution (payment, installment agreement, penalty abatement) vs. criminal charges (fines, restitution, imprisonment).
Immediate steps to take if you are notified or suspect an investigation
- Stop and secure records
- Immediately preserve all payroll records, bank statements, payroll service files, timesheets, and electronic accounting backups. Do not alter or destroy documents (destroying or falsifying records can be a separate crime).
- Consult experienced advisors promptly
- Retain a tax attorney who has experience with IRS‑CI matters and a CPA who understands payroll tax compliance. In my experience, early counsel prevents well‑intentioned statements from being used as admissions.
- Limit who talks to investigators
- Only designated representatives (your attorney or authorized tax professional) should respond to criminal investigators. Employees may be compelled to speak; coordinate this through counsel.
- Respond to civil notices while you prepare for criminal defense
- Do not ignore collection notices or demands. Simultaneously arrange for accurate reconciliations and consider interim payments where appropriate.
- Avoid unilateral voluntary disclosures without counsel
- While voluntary correction can help in civil matters, making unsupervised admissions during a criminal inquiry can worsen exposure. Discuss voluntary disclosure strategy with counsel first.
How investigators build a case (what they’ll look for)
Investigators reconstruct payroll histories using bank deposits and withdrawals, canceled checks, payroll service data, vendor invoices, and employee statements. They focus on:
- Timing: Were deposits skipped, late, or diverted to other uses?
- Beneficial use: Did owners/directors use payroll funds for personal benefit while telling employees taxes were withheld?
- Record manipulation: Are payroll ledgers edited, missing entries, or backdated?
- Admissions: Email, text messages, or testimony that show knowledge of unpaid taxes and a deliberate decision not to remit them.
If the IRS‑CI believes they have probable cause, they may secure subpoenas, execute search warrants, and coordinate with DOJ for potential charges.
Civil relief options and mitigation that matter during criminal reviews
Even amid a criminal inquiry, you should pursue appropriate civil remedies to reduce exposure:
- Correct returns and file delinquent Forms 941/940 promptly. The IRS favors correction but timing and presentation matter when criminal intent is alleged.
- Pay or arrange payment of the trust fund portion as a priority — unpaid withheld taxes are treated as trust fund liabilities and are not dischargeable through ordinary relief programs.
- Trust Fund Recovery Penalty (TFRP): Individual officers and responsible persons can be assessed 100% of the unpaid trust fund portion. You can appeal or request administrative review — do so with counsel. (IRS TFRP guidance.)
- Penalty abatement: For civil penalties (late deposit, failure to file), reasonable‑cause documentation can reduce or remove penalties, but not criminal exposure.
- Installment agreements and offers in compromise: These can help resolve civil tax debts; however, offers in compromise are rarely accepted for trust fund liabilities.
How to reduce the risk of criminal referral (preventive controls)
- Prioritize trust fund deposits: Treat withheld taxes as the business’s top short‑term liability.
- Implement robust payroll controls: Reconcile payroll each pay period, use segregated accounts for payroll taxes where feasible, and require checks and balances for payroll sign‑offs.
- Use reputable payroll processors and verify reporting: If you outsource, review returns and bank deposits monthly.
- Keep written documentation for payroll decisions and corrections: If you must delay payment for cash flow, document the business rationale and efforts to remedy the shortfall.
- Train staff and update corporate governance: Ensure officers understand personal liability exposure for trust fund taxes.

Potential criminal penalties and typical resolution paths
- Criminal penalties for tax evasion or willful failure to collect/turn over tax can include fines, restitution, and imprisonment. Convictions are pursued when evidence shows deliberate intent to defraud the government.
- Typically, cases that progress to prosecution involve large unpaid trust fund amounts, repeated deliberate conduct, or attempts to conceal evidence.
- Many matters resolve civilly if parties quickly correct liabilities and cooperate — but once IRS‑CI opens a case, protection of rights and counsel involvement are critical.
Common misconceptions
- “It’s only a civil matter unless I’m huge.” Wrong — small business owners are frequently investigated.
- “If I pay now, I won’t be in trouble.” Paying mitigates civil consequences but may not eliminate criminal exposure if willful conduct occurred previously.
- “The payroll person is to blame, not the owner.” Employers and responsible officers can be personally liable under TFRP regardless of delegation; oversight matters.
Final checklist if you suspect trouble
- Preserve all records immediately.
- Hire a tax attorney experienced with IRS‑CI prosecutions and a CPA for reconciliation.
- Reconcile payroll and bank records for the past 3–6 years.
- Prioritize remittance of trust fund taxes and document your actions.
- Avoid unsupervised disclosures; coordinate statements with counsel.
- Explore civil resolution options concurrently (installment, penalty abatement) — but only after counsel review.
