Failure to File Penalty
5% of unpaid tax per month, capped at 25%. Applies when you do not file your return by the due date (including extensions). The minimum penalty for returns more than 60 days late is the lesser of $485 or 100% of the tax due. Learn how it interacts with the Failure to Pay penalty (combined cap of 5% per month) and how to qualify for First-Time Abate relief.
Learn MoreFailure to Pay Penalty
0.5% of unpaid tax per month, capped at 25%. Applies when you do not pay the tax shown on your return by the due date. The rate increases to 1% if a notice of intent to levy is issued and the tax remains unpaid. Learn how the penalty applies even if you file on time, and how installment agreements and CNC status can reduce or suspend accrual.
Learn MoreEstimated Tax Penalty
Applies when you underpay estimated taxes during the year — common for self-employed individuals, gig workers, and those with significant investment or retirement income. Covers the 90% safe harbor, 100%/110% prior-year safe harbor, annualized income installment method, and how to request a waiver for casualty, disaster, or retirement-related underpayments.
Learn MoreAccuracy-Related Penalty
20% of the underpayment attributable to negligence, disregard of rules, or substantial understatement of income tax. Covers the substantial understatement threshold (greater of 10% of correct tax or $5,000), the substantial valuation misstatement penalty (40% for gross valuation misstatements), and the reasonable cause and good faith defense under IRC 6664(c).
Learn MoreNegligence Penalty
A component of the accuracy-related penalty under IRC 6662(b)(1) — 20% of the underpayment resulting from negligence or disregard of rules or regulations. Covers what the IRS considers 'negligent' (failure to make a reasonable attempt to comply, failure to keep adequate records, failure to substantiate items properly), and how to demonstrate reasonable cause and good faith to have the penalty removed.
Learn MoreCivil Fraud Penalty
75% of the underpayment attributable to fraud under IRC 6663 — the most severe civil tax penalty. Unlike negligence, fraud requires the IRS to prove by clear and convincing evidence that you intentionally underpaid tax. Covers the difference between civil fraud and criminal tax evasion, the fraud referral process, and how the fraud penalty cascades onto other penalties and extends the unlimited assessment statute.
Learn MoreTrust Fund Recovery Penalty
Penalty equal to 100% of unpaid trust fund taxes (withheld income tax + employee share of FICA) under IRC 6672. Assessed personally against any 'responsible person' who 'willfully' failed to collect, account for, or pay over trust fund taxes. Covers the responsible person test (authority to sign checks, make deposit decisions, and direct payment priority), the willfulness standard, and defenses against TFRP assessment.
Learn MoreFrivolous Return Penalty
$5,000 penalty under IRC 6702 for filing a tax return that does not contain sufficient information to determine the correctness of the tax liability or contains a position the IRS has identified as frivolous. Covers the 26+ IRS-listed frivolous positions, how the penalty is assessed per return (not per person), and the limited collection due process rights for this penalty type.
Learn MoreInformation Return Penalties
Penalties for failure to file correct information returns (Forms 1099, W-2, 1098, etc.) or furnish correct payee statements. Covers the tiered penalty structure — from $60 per return for corrections within 30 days up to $310 per return for intentional disregard — with annual maximums that vary by business size. Includes the de minimis safe harbor for small dollar errors on payee statements.
Learn MorePayroll Tax Penalties
Comprehensive coverage of penalties for late or unpaid payroll taxes: failure to deposit (FTD) penalty under IRC 6656 (2-15% depending on delay), failure to file Form 941/940 penalties, the 100% penalty for willful failure to collect and pay over trust fund taxes, and the special rules for third-party payroll providers. Covers penalty tiers, abatement options, and how to negotiate with the IRS employment tax unit.
Learn MoreInternational Reporting Penalties
Penalties for failure to file international information returns: Form 5471 (CFC reporting), Form 3520 (foreign trust and gift transactions), Form 926 (property transfers to foreign corporations), and Form 8865 (foreign partnership interests). Penalties start at $10,000 per form per year with additional continuation penalties, and can reach 35% of the value of unreported foreign assets or transfers.
Learn MoreFBAR Penalties
Penalties for failure to file FinCEN Form 114 (FBAR) reporting foreign financial accounts exceeding $10,000 aggregate value. Non-willful violations: up to $10,000 per violation (adjusted for inflation). Willful violations: the greater of $100,000 or 50% of the account balance at the time of violation. Covers the two-tier penalty system, the IRS FBAR penalty mitigation guidelines, and the streamlined compliance procedures.
