# How Long to Keep Your Tax Returns and Records
The Internal Revenue Service sets specific retention rules for tax documents, and knowing them protects you from unnecessary storage clutter while keeping you audit-ready. The general rule is straightforward: keep your tax returns and supporting records for at least three years from the date you filed or the return's due date, whichever is later.
Three years covers the standard IRS audit window. The agency typically has three years to audit a return and request supporting documentation. If you kept poor records or filed late, this cushion matters. A taxpayer who files on October 15 after requesting an extension should count three years from that October 15 date, not the original April 15 deadline.
The three-year baseline extends under specific circumstances. If you underreported income by 25 percent or more, the IRS can audit within six years. This applies to gross income understatement, not just a few missed dollars. The difference between a $50,000 and $40,000 reported income triggers the six-year rule. If you omitted more than 25 percent of gross income, save those records and supporting documents for at least six years.
There is no statute of limitations for fraud or if you never filed a return. The IRS can pursue back taxes indefinitely in these scenarios. This distinction matters for anyone with a gap year without filing or those under criminal investigation for tax evasion.
What records beyond the return itself require retention? The IRS expects you to keep receipts, invoices, bank statements, cancelled checks, charitable donation confirmations, property records, and any documents supporting deductions or credits you claimed. If you itemized deductions, hold receipts for medical expenses, mortgage interest statements, property tax records, and charitable contributions. Self-employed individuals need records of income and business expenses for the same three-to-six-year window.
For mortgage interest, property taxes, and retirement account contributions, many taxpayers receive annual statements from lenders and financial institutions. These documents serve as proof if the IRS questions those deductions. Charitable organizations typically issue receipts or year-end donation summaries. Keep those statements, not just your cancelled checks, since the cancelled check alone may not satisfy the IRS.
Home and investment records require longer retention. If you own rental property, keep records for at least three years after selling the property. The same applies to investment property. Capital gains calculations depend on original purchase price and holding period documentation. Save records documenting improvements or repairs, since those affect your cost basis.
Tax professionals recommend keeping digital copies alongside originals. Scan important documents and store them in secure cloud storage or an external hard drive. This approach prevents loss from fire, water damage, or simple misplacement. Label folders by tax year and type of expense to speed up retrieval if audited.
After the retention period expires, shred tax documents rather than throwing them away. Your Social Security number, bank account details, and other sensitive information appear on tax returns and supporting records. A simple trash disposal invites identity theft.
If you face an audit notice from the IRS, do not discard any records related to that return, regardless of age. Extend your retention indefinitely until the audit concludes and any appeal period passes.
