Yes, the IRS can audit you after 3 years, extending to 6 years if you significantly underreport income (over 25%) or have foreign assets issues, and indefinitely if fraud or failure to file is involved, meaning the standard 3-year window is a general guideline, not a hard limit. While most audits cover the last 3 years, substantial errors or omissions can push the period to 6 years, and complete non-filing or fraud allows the IRS to look back forever.
