IRS civil-penalty data show a large increase in assessments on individual and fiduciary income-tax accounts between fiscal years 2021 and 2025. The increase is concentrated in estimated-tax and failure-to-pay assessments, both of which commonly arise without a traditional examination.
What the five-year data show
- Total assessed penalty entries rose from 33.4 million to 46.7 million.
- Estimated-tax penalty entries rose from 11.1 million to 15.7 million.
- Accuracy-related penalty entries fell from 788,243 to 440,718.
Automatic and return-based penalties account for much of the growth
Estimated-tax entries increased about 42%, and failure-to-pay entries increased from 17.0 million to 24.3 million. The dollars assessed for estimated-tax penalties varied sharply across the series. Statutory underpayment rates may contribute to that result, but the Data Book does not isolate the effect of rates, balances, taxpayer behavior, or timing.
| Penalty measure | FY 2021 | FY 2025 |
|---|---|---|
| Assessed, count | 33,393,194 | 46,748,796 |
| Estimated tax, count | 11,103,032 | 15,734,656 |
| Failure to pay, count | 17,048,457 | 24,251,980 |
| Accuracy-related, count | 788,243 | 440,718 |
Abatement totals are not a grant rate
The IRS abated 3.9 million penalties totaling $7.5 billion on these accounts in FY 2025. That is useful context, but it is not an individual-request success rate. The count includes broad administrative relief and adjustments from different assessments and tax years. It does not establish whether a particular taxpayer will qualify for first-time abatement, reasonable cause, or another statutory exception.
A penalty should instead be evaluated by its type, the governing standard, the record, and the remaining procedure. The firm's penalty-relief guide explains those distinctions.
Supervisory approval can matter in covered cases
Section 6751 creates a written-supervisory-approval requirement for certain penalties, subject to statutory exceptions and timing rules. A timely-approval defect can be dispositive in a covered examination-driven penalty case, but it is not a universal defense and must be assessed penalty by penalty. TIGTA's 2026 review identified significant approval-documentation issues in a defined group of syndicated-conservation-easement cases. Read the TIGTA report listing.
