Keep tax returns and supporting documents for at least three years from the date you filed

The Internal Revenue Service (IRS) can audit your return for three years after you file it. That means you need to hold onto your tax return, W-2s, 1099s, receipts, bank statements, and any other documents you used to prepare it for at least that long. If the IRS contacts you about a return from 2021, you will need to show the papers that back up what you reported.

Three years is the standard rule, but there are situations where you should keep records longer. If you underreported your income by more than 25 percent, the IRS can go back six years. If you did not file a return at all, there is no time limit — the IRS can audit you indefinitely. If you filed a fraudulent return, the same applies.

Most people will never be audited. But if you are, having the documents on hand means you can respond quickly and show the IRS exactly what you reported and why. Without them, you have no way to prove your numbers were correct.

Key Takeaways

  • Keep your filed tax return and all documents used to prepare it (W-2s, 1099s, receipts, bank statements) for at least three years.
  • The IRS has three years to audit most returns, but six years if you underreported income by 25 percent or more.
  • If you never filed a return or filed a fraudulent one, keep records indefinitely because there is no time limit for an audit.
  • After the retention period ends, you can shred or delete the documents, but many people keep them longer for personal record-keeping.

What documents to keep with your tax return

Your tax return itself is the starting point, but the IRS will want to see the papers behind the numbers. Keep the following alongside your return:

  • W-2s from all employers
  • 1099s (1099-NEC for self-employment income, 1099-INT for interest, 1099-DIV for dividends, and others)
  • Receipts and invoices for deductions you claimed
  • Mortgage interest statements (Form 1098)
  • Student loan interest statements
  • Charitable donation records
  • Medical expense receipts (if you itemized)
  • Business expense records (mileage logs, supplies, equipment)
  • Bank and investment account statements
  • Proof of estimated tax payments

If you took a deduction, you should have a document that shows you actually spent the money. A credit card statement alone is not usually enough — the IRS wants to see the receipt or invoice showing what you bought. For charitable donations, keep the receipt from the charity or a bank record showing the transfer.

The more detailed your records, the easier an audit becomes. If you can hand over a folder with every receipt organized by category, the IRS can verify your return in less time and is more likely to accept what you reported.

When to keep records longer than three years

The three-year rule is not absolute. Keep records for six years if you underreported your gross income by 25 percent or more. For example, if your actual income was $40,000 but you reported $30,000, the IRS can audit you for six years instead of three.

If you never filed a return for a year when you should have, or if you filed a return you knew was false, there is no statute of limitations. The IRS can come after you at any point. This is rare, but it means you should keep those records indefinitely — or at least until you are certain the IRS will not pursue the matter.

If you own rental property, have a business, or have ongoing investments, consider keeping records for seven years or longer. These situations often involve complex transactions that span multiple years, and having older records can help if a question arises about a current deduction or basis calculation.

How to organize and store your records

Paper records should be kept in a safe, dry place — a file box in a closet, a filing cabinet, or a safe deposit box. Label each year clearly so you can find what you need quickly if the IRS contacts you. Group documents by category: income, deductions, charitable giving, medical expenses, and so on.

Digital storage is also acceptable. Scan your documents and save them in folders organized by year and category. Use cloud storage (Google Drive, Dropbox, OneDrive) or an external hard drive so you have a backup. The IRS does not require a specific format, but make sure the files are readable and labeled clearly.

Many people use tax software or hire a tax preparer who keeps a copy of the return. That is helpful, but you should still keep your own copies of the supporting documents. If your preparer goes out of business or loses files, you will have your own backup.

What to do after the retention period ends

Once three years have passed (or six years, depending on your situation), you can shred or delete the documents. Use a shredder for sensitive papers like bank statements and tax returns. For digital files, use a secure deletion tool rather than just moving them to the trash.

Many people keep records longer than required anyway — five, seven, or even ten years. There is no harm in that, and it can be useful if you need to look back at past income or deductions for a loan application or personal reference. The choice is yours once the IRS retention period has ended.

If you are unsure whether you have been audited or whether the IRS might contact you about an older return, contact the IRS directly at 1-800-829-1040 or check your IRS account online at irs.gov. They can tell you the status of any return and how long you should hold onto the records.

Special situations: business owners and self-employed people

If you are self-employed or own a business, the record-keeping rules are stricter. Keep all business records for at least three years, but many tax professionals recommend seven years. This includes invoices, receipts, payroll records, bank statements, and profit-and-loss statements.

Business records are often tied to multiple tax years. A piece of equipment you bought in 2021 might still be depreciating in 2024, so you need the original receipt to support the depreciation deduction on your current return. Keeping records longer protects you if the IRS questions the basis or depreciation of any asset.

If you have employees, keep payroll records for at least four years. This includes W-2s, payroll tax returns, and timesheets. The Department of Labor has its own record-keeping rules that sometimes extend beyond the IRS requirement.

Frequently Asked Questions

Can I throw away my tax return after three years?

Technically yes, but most people keep them longer. After three years, the IRS can no longer audit most returns, so the legal requirement ends. However, you might need the return for a mortgage application, loan verification, or personal reference, so many people keep copies indefinitely.

What if I lost my receipts but still have my tax return?

If the IRS audits you and you cannot produce receipts, you will have a harder time proving your deductions. The IRS may disallow them. Going forward, keep receipts with your return. If you have already filed and lost the receipts, there is not much you can do except hope you are not audited.

Do I need to keep the original paper return or is a copy okay?

A copy is fine. Many people keep a digital copy or a photocopy. What matters is that you have the information — the IRS does not require the original signed document. Keep whatever format works for you, as long as it is readable and organized.

How long should I keep records if I am being audited right now?

Keep all records related to the audit indefinitely until the audit is closed and you receive a final information from the IRS. Once the audit is complete and any appeals are finished, you can follow the standard three-year rule for future years.

Do I need to keep receipts for every single deduction?

The IRS requires documentation for most deductions, but the level of detail depends on the type. Charitable donations need a receipt from the charity. Medical expenses need receipts or invoices. For some deductions like the standard deduction, you do not need receipts at all. When in doubt, keep the receipt.
