Most people I talk to about their IRS problem have already built the worst-case scenario in their head. The reality is usually much more manageable. I'm Darrin Mish, and I've been representing taxpayers before the IRS for 32 years. Here's what actually tends to happen.<\/p>\n
This is one of the most common questions I get. People want a number. They want to know if they earn under $X, they are safe. Over $Y, they are doomed.<\/p>\n
It does not work like that.<\/p>\n
The IRS audits returns at every income level. The rates change. The reasons change. The type of audit changes. But there is no income line above which an audit is guaranteed and no line below which an audit is impossible.<\/p>\n
That said, the data tells us a lot about who actually gets audited and why. After 32 years of working tax controversy cases, I can tell you what the numbers really say and what matters more than your income.<\/p>\n
The IRS publishes its audit statistics every year. The 2024 numbers tell the real story.<\/p>\n
Across all individual returns filed, the IRS audits fewer than 1 in 500. That is the headline rate. Total audits in fiscal year 2024 came to 505,514. Of those, 393,783 were correspondence audits handled by mail and 111,713 were field<\/a> audits handled in person or in an IRS office.<\/p>\n But the all-returns rate is misleading because audit rates vary enormously by income bracket.<\/p>\n The pattern is a U shape, not a straight line. Audit rates are higher at the bottom and the top of the income distribution and lowest in the middle.<\/p>\n This part is intuitive. The IRS has limited examination resources and rationally targets returns where the potential additional tax is largest.<\/p>\n A $50,000 audit recovery on a $500,000 return is meaningful. The same percentage adjustment on a $50,000 return generates less than a tenth as much tax. High-income returns also tend to have more complexity – business income, partnerships, K-1 flow-throughs, foreign accounts, investment activity – any of which can generate audit issues.<\/p>\n The IRS has also been under political pressure for years to focus enforcement on higher-income taxpayers. The 2022 Inflation Reduction Act funding included specific direction to expand audits of taxpayers earning over $400,000. The trend has been more audits at the top, not fewer.<\/p>\n This part is less intuitive. Why would the IRS audit someone making under $25,000?<\/p>\n The answer is the Earned Income Tax Credit. EITC returns have a documented high error rate, much of it from improper claiming of qualifying children. The IRS runs a heavy correspondence audit program targeting suspected EITC errors. These audits are cheap to run (everything happens by mail), generate per-case recoveries that are meaningful relative to the refund involved, and they push the audit rate for lower-income brackets above what their average income alone would suggest.<\/p>\n The Taxpayer Advocate Service has publicly criticized the EITC audit program for disproportionately burdening low-income taxpayers, but the program continues at scale.<\/p>\n If you earn between roughly $50,000 and $200,000 with W-2 income and standard deductions, your statistical audit risk is among the lowest in the entire tax system. Returns in this band are simple, well-documented through information matching, and not high-dollar enough to attract resource-intensive examination.<\/p>\n This is the audit donut hole. It is real and it is large.<\/p>\n But “low risk” does not mean “no risk.” Specific items on a return in this income range can still trigger audits regardless of total income. The most common triggers are not about how much you make. They are about what you report and how it looks.<\/p>\n Income matters. But the items on the return that the IRS systems flag matter more on a return-by-return basis.<\/p>\n Most audits start with the Discriminant Inventory Function system. The DIF score is a numerical rating the IRS assigns to every return based on statistical patterns that correlate with errors. The IRS does not publish the formula. It updates the model periodically based on audit results.<\/p>\n Returns with high DIF scores get flagged for human review. A human classifier decides whether the return warrants an audit. If the answer is yes, it goes into the audit inventory.<\/p>\n You cannot directly control your DIF score. But you can avoid the patterns that drive scores up. Disproportionate deductions relative to income. Schedule C losses year after year. Cash-heavy business returns with thin documentation. Large charitable contributions relative to income. Round numbers everywhere. The DIF system was built to flag these patterns.<\/p>\nAudit Rates by Income (2024)<\/h3>\n
