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

The Internal Revenue Service (IRS) can audit your return up to three years after you file it. That three-year window is the baseline: keep your actual tax return, W-2s, 1099s, receipts, bank statements, and any other documents you used to prepare it for at least that long. If you filed on April 15, keep everything through April 15 three years later.

The three-year rule is not a hard stop. The IRS can go back six years if it finds a substantial underreporting of income — typically 25 percent or more of what you reported. And if you did not file a return at all, or filed a fraudulent one, there is no time limit. For most people in most situations, three years is enough. But certain documents and situations call for longer storage.

Key Takeaways

  • The IRS can audit returns for three years after filing, so keep your return and all supporting documents (W-2s, 1099s, receipts, bank statements) for at least that long.
  • Keep records for six years if the IRS suspects you underreported income by 25 percent or more, and indefinitely if you never filed or filed fraudulently.
  • Keep mortgage interest statements, property tax records, and charitable donation receipts for seven years, because they support deductions the IRS scrutinizes closely.
  • Keep records related to home purchases, home improvements, and rental property for as long as you own the property, plus three years after you sell it.
  • You can discard records safely once the retention period ends, but shred them rather than throwing them away to protect your personal information.

When to keep records longer than three years

Certain deductions and income sources draw more IRS attention and require longer storage. If you claimed mortgage interest, property taxes, or charitable donations, keep the statements and receipts for seven years. The IRS audits these deductions more often than others, and you need the original documents to prove them.

If you own or owned rental property, keep all records related to that property — purchase documents, improvement receipts, depreciation schedules, tenant agreements, repair invoices — for as long as you own it, plus three years after you sell it. The same rule applies to a home you sold: keep the purchase deed, closing statement, and records of any improvements you made for three years after the sale. These documents prove your cost basis, which determines how much capital gains tax you owe.

If you received income from self-employment, keep records for seven years. The IRS treats self-employment income as higher-risk, and the longer retention period gives them more time to investigate if they choose to.

What documents to keep with your tax return

Your tax return itself is only part of the picture. Keep everything you used to prepare it: your W-2s and 1099s from employers and financial institutions, receipts for deductions you claimed, bank and credit card statements showing the transactions you reported, cancelled checks, invoices, and mileage logs if you claimed vehicle expenses. If you paid someone to prepare your return, keep a copy of the worksheet they gave you showing how they calculated your numbers.

For deductions, the rule is simple: if you claimed it, keep proof you spent the money. A receipt showing the date, amount, and what you bought is the standard. For charitable donations, keep the receipt from the charity or a bank statement showing the transfer. For medical expenses, keep the invoice and proof of payment. For business expenses, keep the receipt and a note about what the expense was for.

If you filed electronically, you received a confirmation number. Write it down and keep it with your records. If the IRS ever questions your return, that number proves you filed and when.

How to store tax records safely

Tax records contain your Social Security number, bank account information, and income details. Store them where they are protected from theft and fire. A locked filing cabinet in your home works. A safe deposit box at a bank is better. Digital storage — scanning documents and saving them to an encrypted external drive or password-protected cloud service — is also secure, as long as you keep backups.

If you use a tax preparation service or accountant, ask whether they keep copies of your records. Many do, for the same three-to-seven-year period. If they do, you can ask them to store your originals instead of keeping them yourself, though you should still have your own copies as backup.

When it is safe to throw records away

Once the retention period ends, you can discard the documents. Do not simply throw them in the trash. Shred them, burn them, or use a document destruction service. Tax records contain enough personal information that identity theft is a real risk if someone finds them in a landfill or dumpster.

Keep one exception in mind: if you are in the middle of an IRS audit or have received a notice from the IRS about a specific year, do not discard any records related to that year until the audit is closed and any appeals period has passed. The IRS will tell you in writing when you can safely destroy them.

Digital records and e-filed returns

If you filed electronically, the IRS has a copy. You still need to keep your own copy, along with all supporting documents, for the standard retention period. Electronic filing does not change the storage rules — you still need proof of what you reported.

If you scanned documents and discarded the originals, keep the scanned copies for the full retention period. Make sure the scan is clear enough to read all the details: date, amount, and what the expense was for. A blurry photo of a receipt is not proof if the IRS asks to see it.

Frequently Asked Questions

Do I need to keep records if I did not owe taxes that year?

Yes. The IRS can still audit a return where you owed nothing or received a refund. Keep all records for three years regardless of whether you owed money. The audit rules are the same whether you paid or the government paid you.

What if I lost my records and the IRS asks for them?

Tell the IRS immediately that the records are gone and explain why. You can reconstruct some information from bank statements, credit card statements, or copies the IRS has on file. The IRS may accept reconstructed records, or they may disallow the deduction. Losing records does not automatically mean you owe money, but it makes your case harder to defend.

Can I throw away my records after I file my next year's return?

No. The three-year clock starts from the date you filed the return, not from the date you filed the next year's return. If you filed your 2023 return on April 10, 2024, keep those records through April 10, 2027, even though you have already filed your 2024 return.

Do I need to keep records for state taxes as well?

Yes. Most states follow the same three-year rule as the IRS, though some states allow longer periods. Check your state's tax agency website for the specific rule in your state. When in doubt, use the longer period — if your state requires seven years and the IRS requires three, keep the records for seven.

Is it okay to keep records on my phone or computer without backing them up?

No. Phones and computers fail, get lost, or are stolen. If you store records digitally, keep at least two copies: one on your computer and one on an external drive or cloud service. That way, if one copy is lost, you still have the other.
