What are the odds of being audited by the IRS depends on several measurable factors — not just chance. An IRS audit is a formal examination of your tax return to verify that reported income, deductions, and credits are accurate. While overall audit rates have declined significantly over the past decade, specific taxpayer profiles carry substantially higher risk. According to the IRS Data Book, the IRS continues to prioritize examinations where potential tax recovery is greatest. This guide explains which filers face the highest IRS audit risk, what triggers closer scrutiny, and how working with a qualified tax debt attorney helps you navigate any audit with confidence and legal protection.
Understanding what are the odds of being audited by the IRS begins with understanding how the IRS chooses which returns to examine. The IRS does not select returns randomly. Instead, it relies on a combination of automated screening and strategic compliance priorities.
The IRS uses a computer-based tool called the Discriminant Inventory Function (DIF) system to score every filed return. Returns that deviate statistically from what similar filers report receive a higher DIF score — and a higher chance of audit selection. According to IRS Publication 556, this scoring system is one of the primary methods the IRS uses to identify returns for examination.
Income level is one of the strongest predictors of IRS audit risk. The IRS Data Book consistently shows that taxpayers reporting higher incomes face greater audit scrutiny than middle-income filers. Taxpayers reporting very high adjusted gross income — particularly those in the highest income tiers — are audited at a significantly elevated rate compared to average filers. On the other end of the spectrum, lower-income filers who claim the Earned Income Tax Credit (EITC) also face disproportionately high audit rates, as noted in a 2023 report by the Treasury Inspector General for Tax Administration.
Knowing what are the odds of being audited by the IRS is only part of the picture. Equally important is understanding which specific return characteristics draw IRS attention and increase examination risk.
Common IRS audit triggers include:
Understanding what are the odds of being audited by the IRS also means being prepared to respond if an audit notice arrives. The IRS is required by law to respect your rights throughout any examination process.
IRS Publication 1 — the Taxpayer Bill of Rights — outlines ten fundamental protections every taxpayer holds during an IRS audit. These include the right to be informed, the right to quality service, the right to challenge IRS positions, and the right to retain legal representation. Under Internal Revenue Code Section 7521, you can stop an IRS interview at any time to consult a qualified tax attorney or enrolled agent.
If the IRS proposes additional tax, penalties, or interest following an audit, you have the legal right to appeal those findings through the IRS Independent Office of Appeals — and, if necessary, to bring your case before the U.S. Tax Court.
What are the odds of being audited by the IRS may be lower than many taxpayers fear — but audit risk is never zero, and certain filers face significantly elevated exposure. Understanding your risk profile, filing accurately, and knowing your legal rights are the three most powerful steps you can take. If the IRS has already contacted you, early legal representation is your most effective defense.

For most individual filers, the IRS audit rate is relatively low, but it is not uniform — income level, filing type, and specific deductions all significantly affect your actual audit risk according to the IRS Data Book.
Yes. Taxpayers who file Schedule C and report consistent business losses — particularly across multiple tax years — face elevated IRS scrutiny, as the agency monitors sole proprietors closely for unreported income and improper deductions.
The IRS will contact you by mail with an official audit notice outlining what records are being examined. According to IRS Publication 556, you have the right to respond, provide documentation, and retain qualified legal representation throughout the process.
A qualified tax debt attorney can review your return before filing to identify high-risk areas, ensure proper documentation, and advise on legally defensible deduction strategies — reducing your audit exposure before the IRS ever flags your return.
Under Internal Revenue Code Section 6501, the IRS generally has three years from the filing date to initiate an audit. However, this window can extend to six years if the IRS identifies a substantial understatement of income, and there is no time limit in cases involving fraudulent returns.
