Keep tax records for at least three years after you file
The Internal Revenue Service (IRS) can audit your return up to three years after you file it, so you need to keep the documents that support what you reported — receipts, W-2 forms, 1099 forms, bank statements, and anything else you used to calculate your income, deductions, or credits. If the IRS contacts you about a return from a prior year, you will need these records to prove what you claimed.
Three years is the standard hold time for most people. However, the IRS can go back further if it suspects underreported income or fraud, which means keeping records longer protects you in those situations. The specific documents you need depend on what you claimed on your return.
Key Takeaways
- Keep all tax records for at least three years after filing, because the IRS can audit returns within that window.
- If you underreported income by 25 percent or more, the IRS can audit up to six years back, so keep those records for six years instead.
- Keep records related to property purchases, home improvements, and retirement accounts for as long as you own the asset, plus three years after you sell it.
- Store records in a safe, organized place — either a filing cabinet, safe deposit box, or scanned digital copies — so you can find them quickly if audited.
When six years is safer than three
If you reported less than 75 percent of your actual income on a return, the IRS considers that a substantial underreporting and can audit you for six years instead of three. You may not know whether you hit that threshold until an audit begins, so if you suspect you made a significant error on an older return, keep those records for six years to be safe.
The six-year rule also applies if you filed a return late or did not file at all. Once you do file, the clock starts, and the IRS has six years to come back to you about that year's income.
Keep property and investment records much longer
If you bought a house, rental property, stocks, or other assets, keep the purchase documents, receipts for improvements, and sale paperwork for at least three years after you sell the asset. The IRS uses these records to calculate your capital gain or loss, which affects your tax bill in the year you sell.
For a primary residence, you may not owe tax on the gain at all if it falls under the exclusion limit, but you still need the records to prove your purchase price and the cost of any improvements. For rental property or investment accounts, the records are essential because the IRS will compare your reported gain to the documents you kept.
If you never sell the asset — you pass it to your heirs or donate it — you can discard the records once the three-year audit window closes for the year you bought it. However, your heirs will need those records if they eventually sell, so consider passing them along.
Retirement account records need special handling
Keep statements from IRAs, 401(k)s, and other retirement accounts for as long as the account exists, plus three years after you close it or withdraw all the money. These records show your contributions, which matter because you may have already paid tax on some of that money and should not pay tax again when you withdraw it.
If you made nondeductible contributions to a traditional IRA, you must file Form 8606 with your tax return and keep a copy forever — or at least until you have withdrawn all the money from all your traditional IRAs. The IRS uses this form to track which portion of your withdrawals is taxable, so losing the record can cost you thousands in unnecessary tax.

The safest way to store and organize records
Paper records fade, get lost, or are destroyed in fires or floods. A safe deposit box at a bank costs $25 to $100 per year and protects important documents like property deeds and original receipts. For everyday tax records, a fireproof filing cabinet at home works if you organize it by year and keep a list of what is inside.
Scanning documents and storing them on a computer or cloud service (Google Drive, Dropbox, OneDrive) is faster to search and takes up no physical space. Take clear photos or scans of both sides of each document, name the files by year and type, and keep backups in at least two places. The IRS accepts digital copies as evidence in an audit, so scanned records are just as valid as paper.
Whatever method you choose, write the year on the outside of each folder or file so you know when you can throw it away. After three years (or six if you underreported income), you can shred or delete the records safely.
What happens if you do not have the records
If the IRS audits you and you cannot find the receipts or statements to back up what you claimed, the IRS can disallow those deductions or credits. You will owe the tax you should have paid, plus interest and penalties. The longer ago the return was filed, the more interest accumulates.
If you lost records by accident, explain that to the IRS during the audit. You may be able to reconstruct some information using bank statements, credit card statements, or written statements from the people or organizations involved. The IRS is more lenient if you show good faith effort to find the records than if you straightforward have nothing.
Frequently Asked Questions
Can I throw away tax records after three years?
Yes, if you reported your income accurately and did not underreport by 25 percent or more. If you are unsure whether you reported everything correctly, keep the records for six years instead. For property and investment records, keep them for three years after you sell the asset, not three years after you file the return.
Do I need to keep copies of my actual tax return?
Yes. Keep a copy of every return you file, permanently. You may need it to prove what you reported in a prior year, to calculate basis for an asset you are selling, or to show the IRS if they contact you about an old return. A copy takes almost no space if scanned.
What if I filed an amended return?
Keep the amended return and all supporting documents for three years from the date you filed the amendment, not the date you filed the original return. The three-year window restarts when you file the amended version.
Do I need to keep receipts if I have a bank statement showing the charge?
A bank or credit card statement shows that you spent money, but not what you spent it on. For deductions like medical expenses, charitable donations, or business expenses, the IRS wants to see the receipt or invoice that describes what was purchased. Keep both the statement and the receipt.
Is it safe to store tax records in the cloud?
Yes, as long as you use a service with strong security and encryption, like Google Drive, Microsoft OneDrive, or Dropbox. Use a strong password and enable two-factor authentication. Keep a backup copy in another location in case your account is hacked or the service shuts down. The IRS accepts digital copies as evidence in audits.
