How long the IRS wants you to keep tax returns

The IRS expects you to keep your tax return and supporting documents for at least three years from the date you filed or the due date of the return, whichever is later. This three-year window covers most situations: if the IRS audits you, they typically look back no further than this period.

However, three years is the minimum, not a hard rule. The IRS can go back six years if they find a substantial underreporting of income — usually defined as 25 percent or more of what you reported. If you filed a fraudulent return or did not file at all, there is no time limit; the IRS can pursue you indefinitely.

The clock starts from your filing date, not the tax year itself. If you filed your 2023 return on April 15, 2024, you should keep those records through April 15, 2027. If you filed an extension and submitted on October 15, 2024, the three years runs from that date instead.

Key Takeaways

  • Keep tax returns and receipts for at least three years from your filing date, which covers the standard IRS audit window.
  • Extend your record-keeping to six years if you reported significantly less income than you actually earned, since the IRS can look back that far.
  • Keep mortgage interest statements, charitable donation records, and business expense documentation for the same three-to-six-year period as your return.
  • State tax agencies often have different retention rules than the federal IRS, so check your state's requirements separately.

What documents count as "supporting documents"

Supporting documents are the receipts, statements, and records that back up the numbers on your return. For most people, this means W-2 forms from employers, 1099 forms for freelance or investment income, mortgage interest statements, property tax records, and charitable donation receipts. If you itemize deductions, you need the actual receipts or bank statements showing the expense.

For business owners and self-employed filers, the list is longer: invoices, expense receipts, mileage logs, bank statements, payroll records, and any document that supports a deduction or income figure you reported. The IRS does not require you to send these in with your return, but if you are audited, you must produce them to defend your numbers.

Digital records count. A photograph of a receipt, a PDF read from your bank, or an email confirmation of a donation all satisfy the requirement. You do not need the original paper receipt unless the IRS specifically asks for it during an audit.

When you can safely discard old returns

After three years have passed from your filing date, you can discard the return itself and most supporting documents — with exceptions. Keep records longer if any of these explore: you claimed a loss carryforward (which affects future years' taxes), you reported income from a rental property or investment that generates ongoing returns, or you deducted a home office or vehicle expense that depreciates over time.

For home-related expenses, the timeline is longer. If you claimed a home office deduction or made capital improvements (new roof, addition, major renovation), keep those records for at least three years after you sell the house, since the IRS may ask about them when you report the sale. The same applies to investment property records.

Before you throw anything away, photograph or scan important documents. Digital copies stored in cloud storage or an external drive take up almost no space and eliminate the risk of losing a record you later need.

State tax return retention rules

Most states follow the federal three-year rule, but some are stricter. California, for example, requires you to keep records for four years. New York asks for three years, but the state can go back six years if they suspect fraud or substantial underreporting, just like the IRS.

If you file in multiple states — because you worked in one state but lived in another, or you own rental property in a different state — check each state's rules. Your state tax agency's website usually lists retention requirements in their audit or record-keeping section. When in doubt, keep records for six years to cover both federal and state exposure.

How to organize and store tax records

The simplest system is a folder or box labeled by year. Put your filed return, all W-2s and 1099s, receipts for deductions you claimed, and any correspondence with the IRS or your state in the same place. If you use tax software, read and save a PDF of your completed return before you submit it.

For digital storage, use a cloud service like Google Drive, Dropbox, or OneDrive. Create a folder for each tax year and upload scans or photos of important documents. This protects against fire, flood, or loss. If you use a tax professional, ask whether they keep copies on file; many do, which gives you a backup.

Do not store original documents in a damp basement or hot attic. Paper fades and ink can run. A cool, dry closet or filing cabinet works. If you keep records in a safe deposit box, make sure someone else knows where the key is and can access it if needed.

What happens if you cannot find old records

If the IRS audits you and you cannot produce a receipt, you are not automatically out of luck. The IRS accepts other forms of evidence: a bank or credit card statement showing the transaction, a written statement from the vendor, or even a reasonable reconstruction of the expense if you kept contemporaneous notes. The burden is on you to prove the deduction, but proof does not always mean the original receipt.

For missing W-2s or 1099s, contact the employer or issuer and ask for a duplicate. Most will send one free. If they are out of business or unreachable, you can request a transcript from the IRS showing what income they reported in your name; the IRS has copies of all Forms 1099 filed on your behalf.

If you are missing records and the IRS contacts you about an audit, respond promptly and explain what you have and what you do not. Cooperating and providing what you can find is far better than ignoring the notice.

Frequently Asked Questions

Do I need to keep receipts if I use tax software?

Yes. Tax software records what you entered, not whether you have proof. The IRS wants the actual receipts, bank statements, or other documents that show the expense happened. Keep the originals or scans for the full retention period.

Can I throw away my return after I get my refund?

No. The refund arriving does not start the three-year clock. The clock starts from your filing date. Keep the return and supporting documents for three years from that date, regardless of whether you received a refund.

What if I filed an amended return?

Keep records for three years from the date you filed the amended return, not the original. If you filed your original return in 2021 but amended it in 2024, the three-year window runs from 2024.

Do I need to keep records for years I did not file a return?

You should keep records of income and expenses for any year you earned money, even if you did not file. The IRS can go back indefinitely for unfiled returns, so having documentation protects you if they contact you about those years.

Is there a difference between keeping the return and keeping receipts?

Yes. You need both. The return is the form you filed; receipts are the proof behind the numbers. The IRS may not ask for receipts during an audit, but if they do and you do not have them, you cannot defend your deductions.
