Keep tax returns for at least three years, and longer if you have self-employment income or investment activity

The IRS can audit your return up to three years after you file it. That is the baseline: keep your tax return itself, plus the documents you used to prepare it (W-2s, 1099s, receipts, bank statements, anything you claimed as a deduction), for three years from the date you filed.

If you underreported your income by more than 25 percent, the IRS has six years to audit you. If you did not file a return at all, or filed a fraudulent one, there is no time limit. For most people filing honestly, three years is the safe minimum.

Self-employed people, investors, and anyone with rental property should keep records longer. The reason is simple: the IRS looks harder at these returns, and the paper trail is more complex. A business loss or depreciation claim can trigger an audit years later.

Key Takeaways

  • Keep your filed tax return and all supporting documents (W-2s, 1099s, receipts, statements) for at least three years from the filing date.
  • If you reported self-employment income, rental income, or investment losses, keep records for seven years or longer.
  • If the IRS contacts you about a specific year, do not throw away documents from that year until the audit is closed and any appeals period has passed.
  • You do not need to keep the original paper forms if you have a clear digital copy or a filed copy from the IRS.
  • State tax agencies may have different retention rules; check your state's requirements separately.

What counts as supporting documents you need to save

Supporting documents are anything you used to fill out your return. For a W-2 employee, that is your W-2 form itself. For someone with a mortgage, it is the mortgage interest statement (Form 1098). For someone who itemizes deductions, it is receipts for charitable donations, medical expenses, property taxes, or state income taxes paid.

For self-employed people, supporting documents include invoices, receipts, bank statements, mileage logs, equipment purchase records, and anything that proves a business expense you deducted. For investors, keep brokerage statements, dividend records, and records of what you paid for each stock or fund you sold.

You do not need to mail paper copies to the IRS when you file. But if you are audited, the IRS will ask for them. Having them organized and ready makes the audit faster and protects you if the IRS questions a deduction.

How long to keep records if you are self-employed or have investment income

Keep records for seven years if you report self-employment income, rental income, or business losses. The reason is that these returns are audited more often, and the IRS may look back further than three years if it suspects a pattern of underreporting.

If you claimed a loss on a rental property or business, keep records even longer — some tax professionals recommend keeping them indefinitely, because a loss can affect your tax position for many years. The same applies if you depreciated an asset: the IRS may ask about it long after you sold it.

For investment accounts, keep brokerage statements and trade confirmations for at least seven years, and longer if you are still holding the investment. When you sell an investment, keep the purchase and sale records for at least seven years after the sale.

What to do if the IRS is auditing a specific year

If the IRS contacts you about a return from a specific year, do not throw away any documents from that year or related years. Keep everything until the audit is complete and any appeals period has ended. An audit can take months or years, and the IRS may ask for documents you did not expect.

If the IRS finds an issue in one year, it sometimes opens audits for adjacent years as well. Keep records from the year before and the year after the year being audited, just in case.

Once the audit is closed and you have received a final letter from the IRS, you can follow the normal retention rules: three years for most people, seven years for self-employed or investment income.

Digital copies versus paper originals

You do not need to keep paper originals if you have a clear, legible digital copy. Scan receipts, bank statements, and other documents and store them in a folder on your computer or in cloud storage. Make sure the image is readable — the IRS will not accept a blurry photo.

If you filed your return electronically, you do not need to keep a paper copy. The IRS has a record of what you filed. You can download a copy of your filed return from the IRS website using your login credentials, or request a transcript.

For documents the IRS sent you (W-2s, 1099s, mortgage interest statements), you can keep the digital version the employer or financial institution sent you. If you received a paper copy, a scan is sufficient.

State tax return records and other considerations

Your state tax agency may have different retention rules than the federal IRS. Some states require you to keep records for four years; others follow the federal three-year rule. Check your state's tax department website for the specific requirement.

If you received a refund, keep records longer. The IRS can ask you to repay a refund for up to three years after it was issued, so hold onto the documents that support the refund.

If you received a notice of deficiency or owe back taxes, keep all related documents indefinitely until the debt is paid and resolved. The same applies if you are in an installment agreement with the IRS.

How to organize and store tax documents

Create a folder for each tax year. Inside, put your filed return, all W-2s and 1099s, receipts for deductions, bank statements, and any other supporting documents. Label the folder with the tax year (for example, "2023 Tax Year").

Store digital copies in a cloud service like Google Drive, Dropbox, or OneDrive so you can access them from anywhere and they are backed up automatically. If you keep paper copies, store them in a file box or filing cabinet in a cool, dry place away from direct sunlight.

Do not throw away documents until you are certain you no longer need them. If you are unsure whether a document is important, keep it. The cost of storage is far less than the cost of not having a document during an audit.

Frequently Asked Questions

Can I throw away my tax return after three years?

If you are a W-2 employee with no business income, rental income, or investment losses, yes — three years is the IRS standard. But if you have self-employment or rental income, keep records for seven years. If you are still being audited or owe back taxes, keep everything until that is resolved.

What if I lost my receipts but filed the return years ago?

If the IRS does not audit that year, it does not matter. If the IRS does audit you and asks for receipts you no longer have, you can try to reconstruct them (bank statements, credit card statements, or a letter from the vendor). Having nothing is worse than having something, so keep what you have.

Do I need to keep W-2s and 1099s forever?

No. Keep them for three years from the filing date if you are a W-2 employee. If you are self-employed or have investment income, keep them for seven years. After that, you can discard them unless you are under audit or still owe taxes.

Should I keep records for years I did not file a return?

Yes. If you did not file a return for a year, the IRS has no time limit to audit you or ask you to file. Keep any documents related to income from that year indefinitely, or at least until the statute of limitations has clearly passed (usually seven years from the year you should have filed).

What if my state requires records longer than the IRS does?

Follow your state's rule. If your state requires four years and the IRS requires three, keep records for four years. You want to be compliant with both the federal and state tax agencies.
