IRS Data Study
The Most Common IRS Penalties, by the Numbers (2026)
The headline number: the most common IRS penalties are about late payment and missed estimated tax — not fraud. In fiscal year 2025, the IRS assessed the failure-to-pay penalty roughly 24.3 million times on individual and estate/trust income tax returns, versus only about 1,400 civil fraud penalties.

If you searched for the most common IRS penalties because a penalty just landed on your bill, here's the reassuring context: you are in extremely large company, and the penalty you're facing is almost certainly an everyday one — the kind that can often be reduced or removed. The rare, scary penalties almost never touch ordinary taxpayers. The data below comes straight from the IRS's own annual report.
Key findings
- Failure-to-pay is #1. The IRS assessed about 24.3 million failure-to-pay penalties on individual and estate/trust income tax returns in fiscal year 2025 — more than any other penalty type.
- Estimated-tax penalties are close behind. About 15.7 million estimated-tax penalties were assessed in FY2025, hitting freelancers, retirees, and anyone whose tax isn't fully withheld.
- Failure-to-file is far less common than failure-to-pay. The IRS assessed roughly 4.0 million delinquency (failure-to-file) penalties — most people file on time but can't pay in full.
- Bad-check penalties are everyday too. About 2.2 million dishonored-payment (bounced check) penalties were assessed in FY2025.
- Accuracy penalties are uncommon. Around 441,000 accuracy-related penalties were assessed — a small fraction of the everyday total.
- Fraud is vanishingly rare. Only about 1,400 civil fraud penalties were assessed on individual and estate/trust income tax returns in FY2025.
- The everyday penalties dwarf the serious ones. Failure-to-pay alone outnumbered fraud penalties by more than 17,000 to 1.

What this means in plain English
Two penalties make up the overwhelming majority of what the IRS hands out: the failure-to-pay penalty and the estimated-tax penalty. Together they account for roughly 40 million of the penalties in this dataset. Both are math-driven and automatic — no one at the IRS decided you did something wrong. The system simply notices you owed money and didn't pay it on time, or didn't pay enough as you went.
The failure-to-pay penalty runs 0.5% of the unpaid tax per month (or part of a month), and interest accrues on top. It's small at first but compounds, which is why acting early matters. You can see how those charges stack up using our IRS penalty and interest calculator, and dig deeper into the data behind the failure-to-pay penalty and estimated tax penalty statistics.
Here's the part that matters most if you're holding a penalty notice: the common penalties are also the most removable. Failure-to-pay and failure-to-file penalties may qualify for first-time penalty abatement when you have a clean recent compliance history, or for reasonable-cause relief if something outside your control — illness, a natural disaster, a death in the family — caused the late payment. The IRS removes a meaningful share of penalties every year; see how often the IRS removes penalties. Whether you qualify depends on your specific facts, and no outcome is guaranteed.
Meanwhile, the penalties people fear most — accuracy and fraud — are rare. Accuracy-related penalties showed up about 441,000 times, and civil fraud only about 1,400 times. If your penalty is one of the everyday ones, you are not being accused of cheating. You're being billed by an automated system, and that bill can often be challenged.
What to do if you have one of these penalties
- Identify which penalty it is. Your notice names it — failure to pay, failure to file, estimated tax, and so on. The two most common are usually the easiest to address.
- Check whether you qualify for first-time relief. If you've filed and paid on time for the past three years, you may be eligible for first-time penalty abatement on a failure-to-pay or failure-to-file penalty.
- Document any reasonable cause. Illness, disaster, or other events beyond your control can support reasonable-cause relief. Keep records.
- Ask in writing. A clear request is the standard way to seek relief; our guide to writing an IRS penalty abatement letter walks through it step by step.
- Deal with the underlying balance. Penalties grow alongside the tax you owe, so a payment plan or other resolution stops the bleeding. Learn more about penalty abatement and your options.
