The Statute of Limitations on Assessments is a crucial tax rule that sets a specific deadline for the Internal Revenue Service (IRS) to audit and reassess your tax returns. This time limit prevents indefinite investigations and provides taxpayers with certainty regarding their tax obligations.
Why the Statute of Limitations Matters
Think of your tax return as a submitted assignment. The IRS acts like a teacher reviewing your work but only within a limited timeframe. After this period, the tax return essentially becomes final. This rule protects taxpayers from unexpected tax claims years after filing and encourages them to file accurate and timely returns.
Standard Time Limits and Key Exceptions
The IRS typically has 3 years from the later of the tax return’s due date or filing date to audit and assess additional taxes. However, this period varies under certain circumstances:
- 3 years: Standard time limit for most returns. For example, for a 2020 return filed by April 15, 2021, the IRS generally must complete audits by April 15, 2024.
- 6 years: If the taxpayer omits more than 25% of their gross income, the statute extends to six years. For instance, if you earned $100,000 but reported only $70,000, the 6-year limit applies.
- No limit: If no tax return is filed, or if fraud is involved, the IRS can audit and assess taxes without any time limit.
- Extended periods: Taxpayers and the IRS may mutually agree to extend the statute, often via a signed consent, which allows more time for review.

Impact for Taxpayers
All U.S. taxpayers—including individuals, businesses, and corporations—are subject to these statute rules. Understanding these limits helps you know how long to retain tax documents and when to expect closure on a tax year.
Recordkeeping Recommendations
While the basic period is three years, it’s advisable to keep tax records for at least 7 years to cover extended scenarios such as substantial underreporting. Retaining records ensures you have documentation if the IRS initiates an audit within the allowable period.
Common Misunderstandings
- Audit anytime: The IRS generally cannot audit beyond the statute period unless exceptional circumstances exist.
- Discard documents early: Many experts recommend keeping tax, income, and related financial records for 7 years or more because of extended statutes or state audit rules.
- 3-year rule applies universally: This is not true; exceptions like fraud or no filing mean unlimited audit time.
Frequently Asked Questions
Can the statute of limitations be paused or extended? Yes, events like agreeing to an extension, leaving the U.S., or certain IRS actions can “toll” or pause this period.
Does this apply to state taxes? State tax agencies have their own statutes of limitations, which may differ significantly from the IRS rules.
What happens when the statute expires? The IRS generally loses the authority to assess additional taxes or penalties for that year.
