Tax audits loom large in the American imagination. The word "audit" conjures images of agents rifling through shoeboxes of receipts, and taxpayer surveys consistently show that audit fear is a primary motivator for compliance. Most people overestimate their personal audit risk by at least an order of magnitude, guessing somewhere between 5% and 10% per year, when the actual rate for the median filer is closer to 0.1%.

The IRS 2024 Data Book reports that the IRS closed 505,514 total tax return audits in FY 2024, of which 444,014 involved individual income tax returns. With approximately 161.1 million individual returns filed, the single-year examination rate is about 0.28%. Compounding over a 59-year adult filing life: 1 - (1 - 0.0028)^59 = 0.152, or about 15%. This is likely an overestimate of any single taxpayer's cumulative risk because audit selection is not random: the IRS concentrates resources on EITC claimants, high-income filers, and returns with specific red flags. A median-income W-2 filer's true annual audit rate is closer to 0.1%, implying a lifetime probability around 6%. The 15% figure represents the population-average rate if audits were distributed uniformly across all filers, which they are not.

The population-average audit rate conceals a U-shaped distribution by income. Filers claiming the Earned Income Tax Credit (under ~$25,000 AGI) face audit rates of 0.3-0.4%, driven almost entirely by correspondence audits verifying credit eligibility. Filers in the $50,000-$500,000 range face rates as low as 0.1%. Filers above $10 million face rates of 4% or higher, though even those rates have fallen steeply since 2010. About 78% of all individual audits in FY 2024 were correspondence audits (conducted by mail), not the in-person field examinations most people picture. The lifetime figure here assumes a constant audit rate, which is unrealistic: rates have varied by a factor of four over the past 15 years alone. A filer who spends their entire career as a median-income W-2 employee has a meaningfully lower lifetime audit probability than the headline figure.

The IRS examined roughly 444,000 individual income tax returns in fiscal year 2024, out of about 161 million filed, an examination rate of approximately 0.28%. That is less than one-third of one percent, and it has been falling for more than a decade. At the peak in FY 2010, the IRS audited about 1.1% of individual returns, roughly 1.7 million per year. Staffing reductions have cut that throughput by more than half, even as the number of returns filed has grown. Compounding the current 0.28% annual rate over a 59-year filing life gives a naive lifetime probability of about 15%, though the true figure for any individual filer depends heavily on income level and return complexity.
The distribution of audits is strikingly non-uniform. The GAO documented a U-shaped pattern by income: filers under $25,000 face elevated audit rates (0.3-0.4%) because correspondence audits targeting Earned Income Tax Credit claims are cheap to run at scale. Filers in the broad middle ($50,000-$500,000) face rates as low as 0.1%. Above $10 million, rates climb to 4% or higher, though even those have fallen by roughly two-thirds since 2010. About 78% of all individual audits in FY 2024 were correspondence audits, conducted entirely by mail, not the in-person field examinations that drive most of the anxiety.
The practical implication is that the population-average rate is a poor proxy for any particular filer’s risk. A salaried employee with straightforward W-2 income and no itemized deductions has a lifetime audit probability well below 10%. A high-income filer with partnership income, foreign accounts, or large charitable deductions faces a meaningfully higher rate. The headline number is real but tells a story about IRS resource allocation as much as it does about any individual’s odds.

- The IRS Data Book is the official annual statistical summary of IRS operations. Of the 505,514 total audits closed, 444,014 were individual income tax returns (the remainder were employment, estate, gift, and excise tax returns). Dividing 444,014 by 161.1 million individual returns gives an examination rate of approximately 0.28%. This rate has been declining for over a decade due to staffing reductions. At the peak in FY 2010, the IRS examined about 1.7 million individual returns per year, roughly 1.1% of filings.

Tax Compliance: Trends of IRS Audit Rates and Results for Individual Taxpayers by Income- Statistic
IRS audit rates for individual taxpayers declined across all income levels from 2010 to 2019; audit rates for higher-income taxpayers decreased more steeply- Excerpt
“"For more than 15 years, IRS audit rates have been steadily declining. IRS officials said audit rates declined due to staffing decreases and because it takes more staff time and expertise to handle complex higher-income audits." ”

- Calculation
- The GAO report provides historical context for the declining audit trend. In FY 2010, the IRS examined about 1.1% of individual returns; by FY 2019, that rate had fallen to roughly 0.4%. The continued decline to ~0.28% in FY 2024 reflects further staffing losses despite Inflation Reduction Act funding. The GAO report also documents that audit rates are not uniform: returns under $25,000 and over $500,000 are audited at higher rates than the middle, creating a U-shaped distribution by income.
