Keep tax records for at least three years after you file

The IRS can audit your return up to three years after you file it. That is the baseline: keep your tax return, W-2s, 1099s, receipts, and any other documents you used to prepare that return for three years from the date you filed. If you filed on April 15, keep everything until April 15 three years later.

But three years is not always enough. The IRS can go back six years if it suspects you underreported income by 25 percent or more. And if you did not file a return at all, or filed a fraudulent one, there is no time limit — the IRS can audit you indefinitely. The safest approach is to keep records longer than three years if you have any doubt about the accuracy of your return.

Key Takeaways

  • The standard record-keeping period is three years from the date you filed your return, not three years from the tax year itself.
  • The IRS can go back six years if it suspects you underreported income by 25 percent or more on a single item.
  • Keep records of major purchases, home improvements, and investment transactions for as long as you own the asset, because you will need them to calculate gain or loss when you sell.
  • State tax agencies often have different record-keeping rules than the IRS, so check your state's requirements separately.
  • Payroll records, business expense records, and employment tax documents should be kept for at least four years.

When the three-year rule does not apply

If you claimed a loss from a worthless security or a bad debt deduction, keep those records for seven years. The IRS treats these claims with extra scrutiny and allows a longer audit window.

If you filed a return late or did not file at all, the three-year clock never starts. The IRS has no deadline to audit you in those cases. If you are unsure whether you filed a particular year, request a transcript from the IRS to confirm.

If you underreported your income by more than 25 percent, the IRS can audit you within six years instead of three. This applies to the entire return, not just the underreported item. The burden is on you to prove the amount you reported was correct, so keep detailed records of all income sources.

Records related to assets and property

Keep records of any major purchase or investment for as long as you own it, plus three years after you sell it. This includes real estate, vehicles, stocks, bonds, and collectibles. You will need the original purchase price, date of purchase, and any improvements or adjustments you made to calculate your gain or loss when you sell.

For a home, keep records of the purchase price, closing costs, and any capital improvements (new roof, addition, major renovation). Do not keep records of routine maintenance like painting or repairs — those are not deductible. Keep these records even after you sell the home, because you may need them if the IRS questions your calculation of the gain.

For investments, keep statements showing the purchase price, date, and quantity. If you reinvested dividends or made other adjustments, keep those records too. Many people lose track of their cost basis over decades of ownership, which leads to overpaying taxes when they finally sell.

Business and self-employment records

If you are self-employed or own a business, keep records for at least four years. This includes invoices, receipts, bank statements, payroll records, and expense logs. The four-year rule applies to payroll tax records even if you are not self-employed — if you paid a household employee or contractor, keep those records for four years.

Keep records of business assets (equipment, furniture, vehicles) for as long as you own them, plus three years after you sell or dispose of them. You will need the purchase price and date to calculate depreciation and gain or loss.

If you claimed a home office deduction, keep records of your home purchase or lease, property taxes, mortgage interest, utilities, and repairs for at least four years. If the IRS questions your deduction, you will need to show the square footage of the office and how you calculated the percentage of your home it represents.

State tax records and special situations

Your state may require you to keep records longer than the IRS does. Some states have a four-year or six-year audit window. Check your state tax agency's website or ask a tax professional what your state requires. If your state has a longer requirement than the IRS, follow your state's rule.

If you received unemployment benefits, keep records of the 1099-G form and any correspondence about the benefits for at least three years. If you received a Paycheck Protection Program (PPP) loan, keep all documentation related to the loan and forgiveness for at least six years, even if the loan was forgiven.

If you claimed education credits, keep records of tuition bills, 1098-T forms, and proof of enrollment for at least three years. If you claimed the Earned Income Tax Credit (EITC), keep records of your income, dependents, and work history for at least three years, because the EITC is audited frequently.

How to organize and store records

Create a folder for each tax year and keep all documents related to that year together: your return, W-2s, 1099s, receipts, bank statements, and any correspondence with the IRS. Label the folder with the tax year and the date you filed.

You can store records on paper or digitally. If you scan paper documents, keep the originals for at least one year in case the IRS asks to see them. Digital copies are acceptable for tax purposes as long as they are clear and complete. Use a secure storage method — a locked file cabinet, a safe, or encrypted cloud storage.

Do not throw away records just because you filed your return. Many people discard documents immediately after filing and then cannot find them if the IRS audits them. Set a calendar reminder for the end of year three to review what you can safely discard.

What happens if you cannot find a record

If the IRS audits you and you cannot locate a receipt or document, you can still defend your deduction or income claim. You may be able to reconstruct the record using bank statements, credit card statements, or other evidence. The IRS will not automatically disallow a deduction just because you do not have the original receipt.

If you lost records in a fire, flood, or other disaster, tell the IRS. You can request a waiver of the record-keeping requirement and provide substitute documentation. Keep a copy of any insurance claim or disaster report to show the IRS.

Frequently Asked Questions

Do I have to keep records if I use tax software or a tax professional?

Yes. Your tax professional or software company does not keep your records for you. You are responsible for maintaining them. Even if someone else prepared your return, you need the original documents if the IRS audits you. The IRS will contact you, not your preparer.

Can I throw away records after three years?

You can, but only if you are certain the three-year window has closed. Count three years from the date you filed, not from the end of the tax year. If you filed on April 10, 2021, you can discard those records on April 10, 2024. If you are unsure, keep them longer — the cost of storage is less than the cost of an audit.

What if I filed an amended return?

Keep records for three years from the date you filed the amended return, not the original return. If you filed an amended return in 2024 for a 2022 tax year, the three-year clock starts from the 2024 filing date. Keep the original return and all supporting documents as well.

Do I need to keep receipts for small purchases?

The IRS does not have a dollar threshold below which receipts are not required. However, for purchases under $75, you can use a bank or credit card statement instead of a receipt if the statement shows the merchant name, date, and amount. For purchases over $75, keep the receipt. For meals and entertainment, keep the receipt regardless of amount.

Should I keep digital copies or paper copies?

Either is acceptable. Digital copies are easier to store and organize, but make sure they are clear, complete, and stored securely. If you scan paper documents, you can discard the originals after one year. Keep at least one backup copy in case your primary storage fails.
