How long the IRS says you need to keep tax returns

The IRS generally recommends keeping your tax return and the documents you used to prepare it for at least three years from the date you filed. This three-year window covers most situations: if the IRS audits you, they typically look back three years from the filing date.

However, three years is a minimum, not a rule that applies to everyone. The actual time you should keep records depends on your specific situation — whether you reported all your income correctly, whether you claimed deductions the IRS might question, and whether you have ongoing tax issues with the agency.

Key Takeaways

  • Keep tax returns and supporting documents for at least three years from the filing date, which covers most IRS audits.
  • If you underreported income by 25 percent or more, keep records for six years instead of three.
  • Keep records indefinitely for any year you did not file a return or filed a fraudulent return.
  • Supporting documents include receipts, bank statements, cancelled checks, and invoices — not just the return itself.
  • State tax agencies may have different retention requirements than the federal IRS, so check your state's rules separately.

When you need to keep records longer than three years

The three-year rule has important exceptions. If you underreported your income by 25 percent or more, the IRS can go back six years instead of three. This applies whether the underreporting was intentional or a mistake. The six-year clock still starts from your filing date, not from when you earned the income.

If you did not file a tax return at all for a particular year, there is no statute of limitations — keep any records related to that year indefinitely. The same applies if you filed a fraudulent return. The IRS can pursue these cases at any point, so holding onto the documents protects you if questions arise later.

If you claimed a loss carryback or carryforward (common with business losses or certain tax credits), keep records for the year you claimed the loss plus the years it affects. These situations are less common for individual filers but matter significantly if they apply to you.

What documents count as "records" you need to keep

The IRS does not require you to keep the actual paper return you filed, though many people do. What matters is keeping the documents that support what you reported on that return. These include:

  • W-2 forms and 1099 forms (income documents from employers and other payers)
  • Receipts, invoices, and bank statements for deductions you claimed
  • Cancelled checks or credit card statements showing payments
  • Mileage logs if you claimed vehicle deductions
  • Medical bills and pharmacy receipts if you itemized medical deductions
  • Mortgage statements and property tax records if you claimed those deductions
  • Charitable donation receipts and acknowledgment letters
  • Records of business income and expenses if you were self-employed

You do not need to keep every piece of paper forever. Once the retention period for a particular year ends, you can safely discard the supporting documents for that year. However, if you are unsure whether the IRS might still question a return, keeping records longer costs nothing and provides protection.

Digital records and how to store them safely

You can keep tax records in digital form instead of paper. Photographs of receipts, scanned documents, and digital copies of bank statements all count. The IRS accepts electronic records as long as they are legible and complete — a blurry photo of a receipt is less useful than a clear one.

If you store records digitally, use a system that will still be accessible years from now. Cloud storage services like Google Drive, Dropbox, or OneDrive are reliable because they are maintained by large companies and you can access them from any device. External hard drives work but require you to maintain the device and ensure it does not fail. Avoid storing critical documents only on your personal computer, which can crash or become obsolete.

Consider keeping at least one backup copy in a different location. If your house floods or burns, digital copies stored only on your home computer are lost. A second copy in cloud storage or on an external drive kept elsewhere protects you against total loss.

State tax record retention requirements

Your state may have different rules than the federal IRS. Some states follow the federal three-year standard, but others require longer retention periods. A few states have no specific requirement and defer to federal guidelines.

Check your state's tax agency website or contact them directly to learn what they require. The retention period for state taxes is separate from the federal period, so you may need to keep records for the longer of the two timeframes. For example, if your state requires five years and the IRS requires three, keep records for five years.

What to do when the retention period ends

Once the retention period for a tax year has passed and you are confident the IRS will not audit that return, you can discard the supporting documents. Shred paper documents or use a document destruction service to ensure sensitive information like Social Security numbers and bank account details cannot be recovered.

Digital files can be permanently deleted, though "permanent" deletion from a computer is not always truly permanent — deleted files can sometimes be recovered. If you want to be thorough, use file-shredding software designed to overwrite deleted files so they cannot be recovered. For most people, standard deletion is sufficient once the retention period ends.

Do not discard records if you have an ongoing dispute with the IRS, a pending audit, or an extension on your return. Keep everything until the matter is fully resolved and any appeals period has ended.

Frequently Asked Questions

Do I need to keep the actual tax return form I filed?

No. The IRS has a copy of your return on file. What matters is keeping the documents that support what you reported — receipts, statements, and forms like W-2s and 1099s. Many people keep a copy of their return for their own records, which is fine, but it is not required.

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

Keep records for the amended return using the same rules as the original return. The retention period is based on the year the income was earned, not the year you filed the amendment. If you amended a 2020 return in 2023, the three-year clock started in 2021 when you originally filed for 2020.

Can I throw away records if the IRS says my return was accepted?

Acceptance means the return was processed, not that it was audited or approved. The IRS can still audit you within three years (or six years if income was underreported significantly). Keep records for the full retention period regardless of acceptance status.

What if I lost my receipts — do I still need to keep the return?

Yes. Keep the return itself and any documents you do have. If the IRS audits you and you cannot produce receipts for a deduction, you may lose that deduction, but you are not penalized for not having the receipt if you can show other evidence (like a bank statement or credit card statement showing the payment).

How do I know if the IRS is going to audit me?

The IRS contacts you by mail if you are selected for audit — never by phone or email initially. If you receive a notice, keep all records related to that return indefinitely until the audit is complete and any appeals period ends. Do not discard anything while an audit is pending.
