IRS Audit Rates by Income: Your Real Odds of Being Audited (2026)
The headline number: the IRS audit rate by income is low for almost everyone. The overall individual audit rate is about 0.5% — roughly 1 in 200 returns. It stays under 1% for nearly every income level below $1 million, then rises sharply, reaching about 4.0% for returns over $10 million.
Key findings
- The overall individual audit rate is about 0.5% — roughly 1 in 200 returns filed.
- Returns reporting under $25,000 are audited at about 0.4%, driven largely by automated checks on refundable credits like the Earned Income Tax Credit.
- The middle of the income range — about $25,000 to $500,000 — has the lowest audit rates, around 0.1% to 0.2%.
- Above $500,000 in total positive income, the rate rises to about 0.6%.
- Audit odds climb steeply at the top: about 1.1% for $1M–$5M, 3.1% for $5M–$10M, and 4.0% for returns over $10 million.
- The pattern is U-shaped — slightly elevated at the bottom, lowest in the middle, and highest at the very top.
IRS audit rate by income: the full table
Figures below are approximate audit rates by total positive income (the IRS term for the sum of positive income amounts on a return, before losses).
| Total positive income | Approximate audit rate | Roughly 1 in… |
|---|---|---|
| All individual returns (overall) | ~0.5% | 1 in 200 |
| Under $25,000 | ~0.4% | 1 in 250 |
| $25,000 – $500,000 | ~0.1% – 0.2% | 1 in 500 to 1 in 1,000 |
| Over $500,000 | ~0.6% | 1 in 167 |
| $1 million – $5 million | ~1.1% | 1 in 91 |
| $5 million – $10 million | ~3.1% | 1 in 32 |
| Over $10 million | ~4.0% | 1 in 25 |
What this means in plain English
If you're a typical wage earner, an audit is unlikely. At an overall rate near 0.5%, about 199 of every 200 returns are never examined. For the broad middle class — roughly $25,000 to $500,000 of income — the published audit rate is even lower, around 0.1% to 0.2%. That's the safest zone in the whole table.
Two parts of the data surprise people. First, the lowest earners get audited a bit more often than the middle class. Returns under $25,000 see about a 0.4% rate, mostly because the IRS uses automated checks to verify refundable credits such as the Earned Income Tax Credit. Many of these are correspondence audits — handled entirely by mail, often just a request for documents — not the in-person exams most people imagine.
Second, audit odds rise fast at the very top. Past $1 million the rate roughly doubles to about 1.1%, then jumps to about 3.1% between $5 million and $10 million, and about 4.0% above $10 million. More income usually means more moving parts — business entities, investments, partnerships — and the IRS focuses its limited examiners where the potential dollars are largest.
One caution: these are averages by income band, not your personal odds. A return with self-employment income on Schedule C, large cash transactions, or deductions that look unusual next to reported income tends to draw more scrutiny than a clean W-2 return at the same income level. The number on the table is a starting point, not a guarantee.
And if you do get a letter, an audit isn't the same as owing money. It's a review. Good records and a calm, organized response matter far more than the odds. If you're facing an examination, our overview of IRS audit representation explains how the process works and what help looks like.

Methodology & source
The figures in this study come from the IRS's own published examination data — the annual IRS Data Book and the agency's compliance-presence statistics. The IRS reports audit (examination) coverage rates for individual income tax returns broken out by total positive income.
We grouped and rounded those published rates into the income bands shown above for readability. "Audit rate" here means the share of filed returns that the IRS examined, including both in-person field audits and mail-based correspondence audits. Because the IRS keeps audits open for several years after a return is filed, rates for the most recent tax years can rise as examinations are completed. We used approximate, rounded figures and did not round in any way that changes the overall story. We did not estimate, model, or invent any number not published by the IRS.

Audit rate questions, answered
What are my real odds of being audited by the IRS?
For most people, very low. The overall individual audit rate is about 0.5%, or roughly 1 in 200 returns. Your odds stay below 1% for almost every income level under $1 million. They climb sharply above that — reaching about 4% for returns reporting more than $10 million in total positive income.
What income level gets audited the most?
The highest earners. Returns reporting more than $10 million in total positive income are audited at about 4.0%, and those between $5 million and $10 million at about 3.1%. The middle of the income range — roughly $25,000 to $500,000 — has the lowest audit rates, around 0.1% to 0.2%.
Why are low-income taxpayers audited at a higher rate than the middle class?
Returns under $25,000 are audited at about 0.4%, higher than the 0.1% to 0.2% rate for many middle incomes. This is driven largely by automated checks on refundable credits such as the Earned Income Tax Credit. Many of these are correspondence audits handled entirely by mail, not in-person examinations.
Does being self-employed increase my audit risk?
It can. Self-employment income reported on Schedule C, large cash businesses, and unusually high deductions relative to income tend to draw more IRS scrutiny than a simple W-2 return. The published rates by income are averages — your specific return's odds depend on what is on it and how well it is documented.
