Keep federal tax records for at least three years

The Internal Revenue Service (IRS) recommends keeping your tax records for a minimum of three years from the date you file your return or the return's due date, whichever is later. This three-year window covers most routine audits, where the IRS examines your return to verify that income, deductions, and credits are accurate and supported by documentation.

The three-year rule applies to records that support what you reported on your tax return: receipts for deductions, proof of income, charitable donation records, medical expense documentation, and mortgage interest statements. If you file early, the clock starts from the official due date (usually April 15), not from when you actually submitted your return.

However, three years is a minimum, not a maximum. Certain situations require you to hold onto records longer, and some people benefit from keeping them even longer than the law requires.

Key Takeaways

  • The IRS standard is three years from your return's due date, but this applies only if you reported income accurately.
  • If you underreported income by 25 percent or more, keep records for six years instead of three.
  • For property records—homes, rental buildings, investments—keep documentation for as long as you own the asset plus three years after you sell it.
  • State tax records may have different retention periods than federal records, so check your state's requirements separately.
  • Mortgage statements, investment records, and retirement account documents should be kept longer than three years because they affect future tax years.

When to keep records for six years instead of three

If you underreported your income by 25 percent or more, the IRS has six years to audit you instead of three. This means you should keep supporting documents for six years in that situation. Underreporting means your actual income was significantly higher than what appeared on your return—for example, if you earned $40,000 but reported only $30,000.

You may not know when ready whether you've underreported income, especially if the discrepancy involves business income, rental income, or investment gains that you discover later. If you suspect an error on a past return, it's safer to keep those records for six years rather than discard them after three.

Property and investment records need longer retention

Real estate, stocks, bonds, and other investments create tax records that extend beyond three years. Keep documentation for any property you own for as long as you own it, plus three additional years after you sell it. This includes the purchase price, improvements you made, repair receipts, and the sale price when you eventually sell.

These records matter because they establish your cost basis—the amount you paid for the asset. When you sell a home, rental property, or investment, the IRS calculates your taxable gain or loss using your cost basis. If you can't prove what you paid, the IRS may assign a basis that results in a larger tax bill. For a home you bought 20 years ago and sold last year, you'd keep those original purchase documents plus three more years of records after the sale closes.

Retirement account statements (401k, IRA, Roth IRA) should also be kept for at least three years after you close the account or take a final distribution, because the IRS may ask about contributions, rollovers, or conversions years later.

State tax records may require different timelines

Your state may have its own retention requirements that differ from the federal three-year standard. Some states follow the federal timeline, while others require four, five, or even seven years of record retention. A few states have no specific requirement but allow audits within a longer window, which means keeping records longer protects you.

Check your state's tax department website or contact them directly to learn the requirement for your state. If your state requires records longer than the federal period, follow your state's timeline. If you've lived in multiple states or worked across state lines, you may need to keep records according to the longest requirement among those states.

What documents to actually keep

You don't need to keep the original tax return itself forever, but you do need to keep the documents that support it. These include:

  • W-2 forms and 1099 forms (income documentation)
  • Receipts and invoices for deductions (medical, charitable, business, education)
  • Mortgage statements and property tax records
  • Brokerage statements and investment transaction records
  • Cancelled checks or bank statements showing payments
  • Mileage logs if you claim vehicle deductions
  • Receipts for home improvements or rental property repairs
  • Proof of charitable donations (letters from charities, bank records)
  • Tuition statements and education expense receipts

You can store these as paper copies, digital scans, or photos. The IRS accepts digital records as long as they're legible and complete. Many people photograph receipts with their phone and store them in a folder on their computer or cloud storage, which takes up less space than paper files.

How to organize and store records safely

Create a straightforward system: one folder per tax year, with subfolders for income, deductions, property, and investments. Label documents clearly with the date and what they support. If you scan paper receipts, keep the originals for at least one year in case the IRS asks to see them.

Store digital copies in at least two places—your computer and a cloud service like Google Drive, Dropbox, or OneDrive. This protects you if your computer fails or you lose paper documents to fire or water damage. If you use tax software, many programs store your return and supporting documents in your account, which counts as one backup location.

For records you're keeping longer than three years (property documents, investment records), consider a fireproof safe or safe deposit box for originals. Digital copies should still be backed up separately.

When you can safely discard old records

After you've held records for the required period and the statute of limitations has passed, you can discard them. For most people, this means three years after filing. Before you throw away old tax documents, shred them rather than tossing them in the trash—tax records contain sensitive information like Social Security numbers and bank account details.

If you're unsure whether the statute of limitations has passed, err on the side of keeping records longer. The cost of storing a few extra years of documents is far lower than the cost of not having them if the IRS contacts you. Once you've discarded records, you cannot retrieve them if an audit begins.

Frequently Asked Questions

Do I need to keep the actual tax return form, or just the supporting documents?

You need the supporting documents (receipts, statements, invoices). The return itself is less critical because the IRS has a copy. However, keeping a copy of your filed return alongside your documents makes it easier to remember what you reported and find the right supporting papers if questions arise.

What if I filed an amended return—how long do I keep those records?

Keep amended return records for the same period as the original return: three years from the due date of the amended return. If you amended a 2021 return in 2024, count three years from the 2024 filing date, not the original 2021 date.

Can I throw away records after the IRS doesn't audit me for three years?

Generally yes, but wait until you're certain the statute of limitations has closed. The three-year window doesn't start until you file, so if you filed in April 2022, you can safely discard most records in April 2025. However, if you underreported income significantly or have property records, follow the six-year or longer timeline instead.

Do I need to keep records for years I didn't file a tax return?

If you didn't file a return but should have, the statute of limitations doesn't start until you file one. The IRS can go back and ask for records from unfiled years indefinitely. If you're unsure whether you were required to file, consult a tax professional before discarding any records from those years.

What about receipts for small purchases under $75?

The IRS generally accepts bank or credit card statements as proof of payment for items under $75, even without a receipt. However, if you're claiming a deduction, you still need to show what the expense was for. Keep a note or photo of the item purchased along with your bank statement, or keep the receipt if you have it. The safer approach is to keep all receipts, regardless of amount.
