The IRS generally wants you to keep tax records for at least three years, but some situations require you to hold them much longer

The three-year rule is the baseline: if you file a tax return, keep all documents that support it for at least three years from the date you filed or the return's due date, whichever is later. This covers most households in most years. The IRS can audit a return within three years of filing, and they need to see your receipts, W-2s, 1099s, and deduction records to verify what you reported.

But three years is not the whole story. If you underreported 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—they can pursue you indefinitely. If you file a fraudulent return, the same applies. And if you claim a loss from a worthless security or bad debt, keep those records for seven years. The type of record and the type of claim determine how long you actually need to hold on to paper or digital files.

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 more than 25 percent, the IRS can audit you for six years, so keep records that long if you know you made a significant error.
  • Records related to home purchases, rental property, or investment accounts should be kept for at least seven years or until you sell the asset, whichever is longer.
  • If you did not file a return or filed a fraudulent one, keep all related records indefinitely because there is no statute of limitations.
  • Organize records by year and type—income documents, deductions, charitable contributions, and medical expenses—so you can find them quickly if audited.

The three-year standard for most households

For a typical tax return with W-2 income, standard deductions, and no major claims, three years is sufficient. This is the period during which the IRS has the authority to examine your return and propose changes. If they do not contact you within three years, they generally cannot go back and audit that year.

Start counting from the later of two dates: the date you actually filed the return, or the return's official due date (usually April 15). If you filed your 2023 return on March 1, 2024, count three years from March 1, 2024. If you filed it on October 15, 2024 (with an extension), count from October 15, 2024. Once three years have passed, you can safely discard those records—though many people keep them longer out of habit or caution, which is fine.

When to keep records for six years or longer

The six-year rule applies when you underreport gross income by more than 25 percent. This is a substantial underreporting, not a small math error. If your actual income was $100,000 and you reported $70,000, that is a 30 percent underreporting and triggers the six-year window. Keep all income documents—pay stubs, 1099s, bank statements, invoices—for six years in this case.

Records tied to assets you own should be kept for at least seven years, and often longer. If you own a home, keep the purchase documents, mortgage statements, and records of improvements (new roof, kitchen remodel, foundation work) for seven years after you sell it. The same applies to rental property, investment accounts, and business assets. These records help you calculate your cost basis when you eventually sell, which determines how much capital gains tax you owe. Keep them until at least seven years after the sale closes.

Records related to homes, investments, and business assets

Home purchase documents and improvement records deserve special attention because they affect your taxes for decades. When you sell your home, you report a capital gain equal to the sale price minus your cost basis (what you paid plus the cost of improvements). The IRS wants to see proof of those improvements. Keep receipts for any work that added value: a new roof, foundation repair, kitchen or bathroom renovation, new HVAC system, or deck addition. Keep these records for at least seven years after you sell the home.

If you own rental property or investment accounts, the timeline is similar. Keep purchase confirmations, statements showing dividends or interest, and records of any repairs or improvements for seven years after you sell or close the account. If you have a loss carryforward—a loss from one year that you use to offset gains in future years—keep those records for seven years from the year you claim the loss.

What happens if you never filed a return

If you did not file a tax return for a particular year and the IRS discovers it, there is no statute of limitations. They can go back as far as they want. This is why it is critical to file even if you owe money or think you do not owe anything. Once you file, the three-year (or six-year) clock starts. If you never file, the clock never starts.

If you are behind on filing, gather your records for the unfiled years and file them as soon as you can. The IRS often works with people who come forward voluntarily. Once you file, you are back on the standard timeline.

Organizing records so you can find them during an audit

Keeping records is only useful if you can locate them when you need them. Create a straightforward system: one folder or digital file per tax year, subdivided by category. Use these labels: Income (W-2s, 1099s, pay stubs), Deductions (receipts, invoices, credit card statements), Charitable Contributions (donation receipts, letters from nonprofits), Medical and Dental (bills, insurance statements, pharmacy receipts), and Home/Investment (purchase documents, improvement receipts, sale documents).

If you file electronically, save a copy of your filed return and the confirmation receipt. If you file on paper, keep a copy of what you mailed. Store originals in a safe place—a filing cabinet, safe deposit box, or find cloud storage. Many people photograph receipts and store the images in a folder labeled by year, which saves physical space and makes records easier to find.

Digital records and how long to keep them

Digital records count just as much as paper ones. If you bank online, read and save your statements for the years you need to keep records. If you use accounting software like TurboTax or QuickBooks, export and save a copy of your return and supporting data. Email confirmations of charitable donations, medical bills from your healthcare provider's portal, and digital receipts from online retailers all serve as proof if audited.

The challenge with digital records is that accounts get deleted or closed. If you use a tax preparation service, read your return and all attachments before you close the account. If you use online banking, do not rely on the bank's archive alone—read statements to your own computer or cloud storage. Digital files can be lost to server failures, account closures, or forgotten passwords, so redundancy matters. Keep copies in at least two places: your computer and a cloud service, or your computer and an external hard drive.

Frequently Asked Questions

Can I throw away records after three years?

Yes, for most returns. Three years from the filing date is the standard IRS audit window. However, if you know you underreported income significantly, had investment losses, or own property, keep records longer. When in doubt, keeping records for seven years costs little and protects you against most scenarios.

What if the IRS contacts me about a year I thought was closed?

If they contact you, they have found a reason to reopen that year—usually substantial underreporting or a claim they want to verify. Gather whatever records you still have and respond promptly. Even if you no longer have originals, bank statements, credit card statements, and third-party documents (W-2s, 1099s) can often be reconstructed through your bank or the issuing organization.

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

A credit card statement shows that you made a purchase, but not what you bought or whether it was deductible. Keep the actual receipt or invoice alongside the statement. For charitable donations, the receipt from the nonprofit is what the IRS wants to see, not just a bank transfer. For medical expenses, keep the bill from the provider. The statement alone is usually not enough.

How long should I keep records for a home I sold years ago?

Keep them for at least seven years after the sale closes. If you sold in 2020, keep records through 2027. After that, you can discard them. However, if you still own other investment property or have ongoing tax situations tied to that sale, keep them longer until those situations are fully resolved.

What if I lost my records and the IRS audits me?

Contact the IRS when ready and explain what happened. They understand that records are sometimes lost to fire, flood, or moving. You can request copies of documents they have on file—W-2s and 1099s come from employers and financial institutions, so the IRS often has them. For other deductions, provide whatever documentation you can find: bank statements, credit card statements, or written explanations of what you spent and why it was deductible.
