IRS Form 941: Employer's Quarterly Return
Form 941 is the most dangerous tax form for business owners. It reports income tax withheld, Social Security, and Medicare taxes — the "trust fund" taxes the IRS treats as YOUR employees' money, not yours. Unfiled or unpaid 941s are the #1 trigger for TFRP personal liability assessments.
Why Form 941 Is the Most Dangerous IRS Form
TRUST FUND TAXES: The income tax, Social Security, and Medicare taxes you withhold from employees are called 'trust fund taxes' — the money belongs to your employees and the government, not you. The IRS treats non-payment as essentially theft of trust funds.
PERSONAL LIABILITY (TFRP): If you fail to remit 941 taxes, the IRS can assess the Trust Fund Recovery Penalty against you PERSONALLY under IRC §6672. The penalty equals 100% of the trust fund portion — and the IRS can assess it against officers, owners, and anyone with check-signing authority.
NO BANKRUPTCY DISCHARGE: TFRP assessments cannot be discharged in bankruptcy — they survive Chapter 7 and Chapter 13.
CRIMINAL EXPOSURE: Willful failure to pay over withheld taxes is a felony under IRC §7202 — up to 5 years in prison. The IRS Criminal Investigation Division investigates 941 non-compliance.
