Keep tax records for at least three years after you file

The Internal Revenue Service (IRS) can audit your return for three years after the date you file. That is the baseline: if you file your 2023 taxes in April 2024, keep everything related to that return through April 2027. If the IRS contacts you about that year, you will need receipts, W-2s, 1099s, bank statements, and any other documents that support the numbers you reported.

Three years is the standard window because it is the statute of limitations for most tax disputes. The IRS rarely goes back further unless they find a significant error or suspect fraud. But "rarely" does not mean "never," and certain situations demand longer storage.

Key Takeaways

  • Keep tax records for three years minimum, measured from the date you file your return, not the tax year itself.
  • Keep records for six years if you reported less income than you actually earned, even if the underreporting was unintentional.
  • Keep records indefinitely if you did not file a return for a particular year or if you filed a fraudulent return.
  • Records include receipts, invoices, bank statements, cancelled checks, W-2s, 1099s, and any document proving deductions or income you claimed.
  • The clock starts when you file, not when the tax year ends, so a return filed in April 2024 is protected through April 2027.

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 applies whether the underreporting was intentional or a mistake. The six-year window runs from the date you file, just like the three-year rule.

Example: You earned $50,000 in 2023 but reported only $35,000 on your return filed in April 2024. That is a 30 percent underreporting. Keep all records related to that return through April 2030. If you earned $50,000 and reported $40,000, that is 20 percent underreporting and the three-year rule applies instead.

The burden is on you to know whether you crossed the 25 percent threshold. If you are unsure, the safer choice is to keep records for six years. The cost of storage is far lower than the cost of reconstructing documents years later if the IRS comes calling.

Records you must keep indefinitely

If you did not file a tax return for a particular year, there is no statute of limitations. The IRS can go back as far as they want. The same applies if you filed a return you knew was fraudulent. In both cases, keep all records related to that year permanently.

This also affects records tied to property. If you own a home or investment property, keep records of the purchase price, improvements, and sale price for as long as you own the property, plus six years after you sell it. The IRS uses these records to calculate your basis and capital gains, and they can audit a sale years after it closes.

What documents count as tax records

Tax records are anything that proves the income, deductions, or credits you claimed on your return. This includes:

  • W-2s and 1099s from employers and clients
  • Receipts and invoices for business expenses, medical costs, or charitable donations
  • Bank statements and cancelled checks
  • Credit card statements showing deductible purchases
  • Mortgage statements and property tax bills
  • Mileage logs if you claimed a vehicle deduction
  • Proof of charitable donations (receipts or bank records)
  • Copies of the actual tax returns you filed, including all schedules and attachments

Keep the return itself as well as the supporting documents. A copy of your filed return (the one with the IRS stamp or confirmation number) is proof of what you reported and when you reported it. Digital copies are acceptable; you do not need to print everything.

How to store records safely

Paper records can fade, get damaged, or be lost in a fire or flood. Digital storage is more reliable and takes up no physical space. Scan important documents and save them in at least two locations: your computer and a cloud service like Google Drive, Dropbox, or OneDrive. If you use a cloud service, make sure you can still access it if the company changes its terms or shuts down.

For records you must keep indefinitely—property records, records from unfiled years—consider a safe deposit box at a bank or a fireproof safe at home. These protect against loss and make it harder for someone to steal your identity using old documents.

Label files by year and type: "2023 Tax Return," "2023 Medical Expenses," "2023 Charitable Donations." This makes it faster to find what you need if the IRS asks. If you work with a tax preparer or accountant, ask whether they keep copies on file. Many do, and you can retrieve them if your own copies are lost.

What happens if you cannot find a record

If the IRS audits you and you cannot locate a receipt or statement, you are not automatically disqualified from claiming that deduction. You can reconstruct the record using other evidence: bank statements, credit card statements, cancelled checks, or even a written statement explaining what you spent and why. The IRS will evaluate whether your reconstruction is credible.

The stronger your other evidence, the better your chances. A bank statement showing a $500 withdrawal on the date you claim you paid for a medical procedure is more convincing than your word alone. If you have nothing—no bank record, no credit card charge, no receipt—the IRS will likely disallow the deduction.

This is why keeping records matters even for small expenses. A single missing receipt for a $200 deduction might not trigger an audit, but if the IRS is already looking at your return and finds multiple missing records, it raises red flags about your record-keeping practices overall.

Frequently Asked Questions

Do I need to keep receipts if I have a credit card statement?

A credit card statement shows that you made a purchase and how much you spent, but it does not always show what you bought. For deductions like medical expenses or business supplies, keep the receipt to prove the purchase was deductible. For charitable donations, the charity's receipt is required for donations over $250. A credit card statement alone is usually not enough.

Can I throw away records after three years?

Only if you are certain you meet the three-year rule: you filed the return, you did not underreport income by 25 percent or more, and the return was not fraudulent. If any of those conditions do not apply, keep records longer. When in doubt, keep them. The cost of storage is minimal compared to the risk of being unable to defend a deduction.

What if I filed an amended return?

The three-year clock runs from the date you filed the amended return, not the original return. If you filed your 2023 return in April 2024 and then filed an amended return in August 2024, the IRS has until August 2027 to audit the amended version. Keep records for the longer of the two dates.

Do I need to keep records for years I did not owe taxes?

Yes. If you filed a return showing zero tax owed, the IRS can still audit it to verify that your income and deductions were reported correctly. Keep records for three years from the filing date, just as you would for any other return. If you did not file a return at all for a year you should have, keep records indefinitely.

Are digital copies acceptable to the IRS?

Yes. The IRS accepts digital copies, scans, and photographs of receipts and documents. Make sure the image is clear enough to read all the important details: date, amount, and what was purchased. Keep the original documents as backup if possible, but if you only have a digital copy, that is better than having nothing.
