How Often Do People Get Audited by the IRS | What You Should Know

Q: 1. How often do people get audited by the IRS each year?

According to the IRS Data Book , the IRS audits millions of returns annually, though audit rates for individual filers have declined significantly since the early 2010s. Your personal audit risk depends heavily on your income level and filing complexity.

Audit Basics Explained: How Often Do People Get Audited by the IRS

How often do people get audited by the IRS is a question every taxpayer deserves a direct answer to. IRS audit rates have declined over the past decade, yet millions of Americans still receive audit notices each year. Receiving one can feel alarming — especially when you already carry unresolved tax debt or complex filing history. This guide explains how the IRS selects returns for examination, which taxpayers face the greatest audit exposure, and what tax relief options exist when an audit leads to additional tax liability. Understanding this process puts you in a stronger legal position from the start.

How the IRS Decides Which Returns to Audit

The IRS does not review every return filed in a given year. It uses a combination of automated tools and specific risk indicators to identify which returns require closer examination.

The primary selection mechanism is the Discriminant Inventory Function (DIF) system — an automated scoring model that evaluates how significantly a return’s reported deductions, credits, and income deviate from statistical norms. Returns with elevated DIF scores receive increased scrutiny. According to the IRS Audit Selection overview, the DIF system is one of the most consistent drivers of individual return examination activity.

Beyond automated scoring, the IRS cross-references third-party documents — W-2s, 1099s, and mortgage interest statements — against your filed return. Any discrepancy between those records and your reported figures can independently trigger an IRS audit, regardless of your DIF score.

IRS Audit Rates Are Changing — What the Data Shows

How often do people get audited by the IRS shifted considerably over the past decade. Audit activity fell sharply following budget reductions to IRS enforcement staffing during the 2010s. According to the IRS Data Book (irs.gov/statistics/irs-data-book), individual return audit rates dropped to historic lows during this period.

However, the Inflation Reduction Act of 2022 directed substantial new funding toward IRS enforcement. As reported by the U.S. Department of the Treasury (home.treasury.gov), the IRS has committed to focusing this enforcement capacity on high-income filers, complex business returns, and large partnerships — not on routine middle-income wage earners.

Which Taxpayers Face the Highest Audit Risk

Certain return characteristics consistently lead to elevated IRS audit selection:

Self-employment income on Schedule C with significant business expense claims
Large or disproportionate charitable contribution deductions relative to reported income
Foreign financial account disclosures required under FATCA
Prior audit history or existing unresolved tax debt with the IRS
Unreported income identified through third-party document matching

Common Tax Challenges: When an IRS Audit Creates or Worsens Tax Debt

An IRS audit does not automatically result in additional taxes owed. But when examiners identify unreported income, disallowed deductions, or documentation gaps, the outcome can include a significant tax debt assessment along with civil penalties and compounding interest.

Under Internal Revenue Code Section 6662, the IRS may impose an accuracy-related penalty on underpayments resulting from negligence or substantial understatement of tax liability. Interest accrues from the original return due date, increasing the total balance owed over time.

4. Do I need a tax attorney during an IRS audit?

While legal representation is not legally required, a qualified tax debt attorney can communicate directly with the IRS on your behalf, protect your rights under the Taxpayer Bill of Rights (IRS Publication 1), and improve your likelihood of a favorable resolution — particularly when significant tax debt is involved.
