Keep federal tax records for at least three years after you file

The Internal Revenue Service (IRS) expects you to keep the records that support your tax return for at least three years from the date you file or the date the return was due, whichever is later. This three-year window covers most situations: if the IRS audits you, they typically look back three years. If you kept poor records or made a significant error, they may go back six years. If they suspect fraud, there is no time limit.

What counts as supporting records? Receipts, invoices, bank statements, cancelled checks, payroll stubs, mortgage statements, charitable donation receipts, medical expense records, and any document that proves the income or deduction you claimed on your return. You do not need to send these to the IRS when you file—you keep them at home. The IRS only asks to see them if they contact you.

The three-year rule is a floor, not a ceiling. Certain situations require you to hold onto records longer, and some people choose to keep them indefinitely for their own protection.

Key Takeaways

  • Keep tax records for at least three years from the date you file or the due date, whichever comes later.
  • If you underreported income by 25 percent or more, the IRS can audit back six years instead of three.
  • Records tied to property (home, rental property, investments) should be kept for at least three years after you sell the asset.
  • Charitable donations, medical expenses, and business deductions each need their own supporting documents for the full three-year period.
  • Keeping records longer than three years costs little and protects you if the IRS questions your return years later.

When six years is the safer timeline

The IRS can extend the audit window from three years to six years if they find that you underreported your income by 25 percent or more. This is not a judgment call on your part—if the IRS decides to audit and discovers a significant underreporting, they have the legal right to go back six years. To protect yourself, keep records for six years if you are self-employed, have rental income, or receive income from multiple sources where the amounts are harder to verify.

You should also keep records for six years if you claimed a home office deduction, business vehicle expenses, or other deductions that rely on calculations or estimates. These are areas the IRS scrutinizes more closely, and having six years of documentation means you can defend your position if questioned.

Property records need to stay longer than three years

If you own a home, rental property, or investment property, keep all records related to that property for at least three years after you sell it. This includes the purchase deed, closing statement, receipts for improvements or repairs, property tax bills, and mortgage statements. The IRS uses these records to calculate your cost basis—the original price plus improvements—which determines how much capital gains tax you owe when you sell.

For example, if you bought a house for $300,000, spent $50,000 on a new roof and kitchen, and sold it for $450,000, your cost basis is $350,000, not $300,000. Without documentation of that $50,000 in improvements, the IRS may assume your basis is lower, and you could owe tax on gains you did not actually make. Keep those improvement receipts for the life of your ownership plus three years after sale.

Business and self-employment records

If you are self-employed or own a business, the three-year rule still applies to your tax return, but your business accounting records should be kept longer. Many accountants recommend keeping business records for seven years, because business audits can be more complex and the IRS may want to see patterns across multiple years. Payroll records, if you have employees, must be kept for at least four years under federal law, separate from the tax record rule.

Keep receipts for all business expenses you deducted: supplies, equipment, vehicle mileage logs, meals and entertainment, travel, and professional services. If you claimed depreciation on equipment or vehicles, keep the purchase receipts and depreciation schedules for the entire time you own the asset, plus three years after you sell or dispose of it.

Charitable donations and medical expenses

Charitable donations require written acknowledgment from the charity for donations of $250 or more. Keep that letter along with your bank statement or cancelled check showing the donation. For donations under $250, a bank record or receipt from the charity is enough. Hold onto all of these for three years from the date you file the return claiming the deduction.

Medical and dental expenses that you deduct must be supported by receipts, bills, and insurance statements showing what you paid out of pocket. If you deducted mileage to medical appointments, keep a log showing the dates, destinations, and miles driven. These records should be kept for three years, but many people keep them longer because medical expenses can be audited more frequently than other deductions.

What format to use and how to store records

You can keep records on paper, digitally, or both. The IRS does not require a specific format. Many people photograph receipts and store them in a folder on their computer or cloud storage, which saves space and makes them searchable. If you scan documents, make sure the scan is clear enough to read all the details—date, amount, what was purchased, and who sold it to you.

Whatever format you choose, keep a backup. If your computer fails or you lose a folder of papers, you want a second copy. Cloud storage (Google Drive, Dropbox, OneDrive) automatically backs up your files. For paper records, consider storing originals in a fireproof box or safe deposit box, especially for property deeds and major purchase receipts.

Do not throw away records the moment the three-year window closes. If you have the space, keeping them for seven or ten years costs nothing and protects you if the IRS comes back with questions years later. Many people keep tax records indefinitely for peace of mind.

What you can safely discard

After three years (or six if you are self-employed or have complex income), you can discard receipts for routine expenses that are no longer relevant: grocery store receipts, gas station receipts, utility bills from years past (unless they support a deduction you claimed). You can also discard bank statements once you have reconciled them and confirmed they match your tax return.

Do not discard anything related to property ownership, investments, or ongoing business until well after you have sold the asset and the three-year window has closed. Shred documents rather than throwing them in the trash, because they contain personal financial information.

Frequently Asked Questions

Can I throw away my tax return itself after three years?

You can, but many people keep copies of their filed returns indefinitely. A copy of your return is useful if you need to reference past income for a loan process, mortgage refinance, or to verify what you claimed in previous years. Keeping a digital copy takes almost no space.

What if I file my taxes late—does the three-year clock start from when I file or from the due date?

The clock starts from whichever is later: the date you actually filed or the date the return was due (usually April 15). If your return was due April 15 but you filed on June 1, the three years runs from June 1. If you filed early, it runs from the due date.

Do I need to keep records if I did not claim any deductions?

Yes. You should keep records that show your income—W-2 forms, 1099 forms, bank statements showing deposits, or payroll stubs—even if you took the standard deduction. These prove what you reported if the IRS ever questions your return.

What about old tax returns from before I started filing electronically?

Keep paper copies of old returns for at least three years from the date you filed them, or longer if they relate to property you still own or ongoing business. Once that window closes, you can discard them, but many people keep them for their records.

If the IRS audits me, do I have to produce original receipts or are copies okay?

Copies are usually acceptable, especially if they are clear and legible. The IRS understands that original receipts fade or get lost. If they question a copy, you can explain that you no longer have the original. Having something is far better than having nothing.
