Last year out of over 160 million individual income tax returns that were filed, the IRS audited 659,003 – or just 4 out of every 1,000 returns filed (0.4%). This was only slightly lower than the overall odds of audit from FY 2019, and above FY 2020 levels where just 3 out of every 1,000 returns filed were examined[1].
Audit rates for taxpayers with incomes between $200,000 and $500,000 saw the biggest drop (a 92% drop), from 2.3% in 2010 to 0.2% in 2019. For the highest income taxpayers, those with income of $10 million or more, the audit rate dropped from 21.2% in 2019 to just 3.9% in 2019 (an 81% drop).
People reporting adjusted gross income (or AGI) of $10 million or more accounted for 6.66% of audits in fiscal year 2018. Taxpayers reporting an AGI of between $5 million and $10 million accounted for 4.21% of audits that same year. But being a lower-income earner doesn't mean you won't be audited.
What Are the Chances of Being Audited? Americans filed just over 157 million individual tax returns in fiscal 2020. In the same year, the IRS completed 509,917 audits, making your overall odds of being audited roughly 0.3% or 3 in 1,000. IRS audits are conducted by mail and in person.
Key Takeaways. Your tax returns can be audited even after you've been issued a refund. Only a small percentage of U.S. taxpayers' returns are audited each year. The IRS can audit returns for up to three prior tax years and, in some cases, go back even further.
Does the IRS Catch All Mistakes? No, the IRS probably won't catch all mistakes. But it does run tax returns through a number of processes to catch math errors and odd income and expense reporting.
What is the chance of being audited by the IRS? The overall audit rate is extremely low, less than 1% of all tax returns get examined within a year.
Audit trends vary by taxpayer income. In recent years, IRS audited taxpayers with incomes below $25,000 and those with incomes of $500,000 or more at higher-than-average rates. But, audit rates have dropped for all income levels—with audit rates decreasing the most for taxpayers with incomes of $200,000 or more.
If the IRS finds that you were negligent in making a mistake on your tax return, then it can assess a 20% penalty on top of the tax you owe as a result of the audit. This additional penalty is intended to encourage taxpayers to take ordinary care in preparing their tax returns.
The IRS Review Process: Every Return Is Reviewed by Computer
Once the data is in the system, a computer checks the return for errors, such as mathematical errors; if none are found, the return is processed, and the IRS issues you either a refund or a balance due notice.

According to a Treasury Inspector General testimony, between 2014 and 2016, nearly 880,000 high-income people owing more than $45 billion failed to file their taxes, and the IRS is unlikely to go after them. Audits of the rich continue to drop while audits of the poor have stayed the same.
Generally, the IRS can include returns filed within the last three years in an audit. If we identify a substantial error, we may add additional years. We usually don't go back more than the last six years. The IRS tries to audit tax returns as soon as possible after they are filed.
On the poorest households in America. The relevant statistics come to us via TRAC, a nonprofit research data center at Syracuse University. TRAC recently mined IRS statistics and determined that the agency audits households with less than $25,000 in income at five times the rate for anyone else.
The IRS conducts tax audits to minimize the “tax gap,” or the difference between what the IRS is owed and what the IRS actually receives. Sometimes an IRS audit is random, but the IRS often selects taxpayers based on suspicious activity.
The Short Answer: Yes. The IRS probably already knows about many of your financial accounts, and the IRS can get information on how much is there. But, in reality, the IRS rarely digs deeper into your bank and financial accounts unless you're being audited or the IRS is collecting back taxes from you.
It may be. Sometimes the IRS will catch your missing W-2 and send you a letter letting you know about the missing information and they will correct it for you or if you have other issues on your return they may reject it. So, in the meantime, you will need to wait to see if it is processed or not.
Fortunately, you don't need to worry about that happening. According to the IRS, most tax audits are regarding returns filed within the last three years. If they find a substantial error, they may add more years. But even then, they seldom go back more than six years.
Audits can be bad and can result in a significant tax bill. But remember – you shouldn't panic. There are different kinds of audits, some minor and some extensive, and they all follow a set of defined rules. If you know what to expect and follow a few best practices, your audit may turn out to be “not so bad.”
If you get audited and don't have receipts or additional proofs? Well, the Internal Revenue Service may disallow your deductions for the expenses. This often leads to gross income deductions from the IRS before calculating your tax bracket.
You cannot go to jail for making a mistake or filing your tax return incorrectly. However, if your taxes are wrong by design and you intentionally leave off items that should be included, the IRS can look at that action as fraudulent, and a criminal suit can be instituted against you.
Lying on your tax returns can result in fines and penalties from the IRS, and can even result in jail time.
Tip. You can take some comfort in the fact that the Internal Revenue Service audits less than 1 percent of all tax returns each year.
