The IRS wants you to keep most tax records for three years

The standard record-keeping period is three years from the date you file your return or the return's due date, whichever is later. This covers your tax return itself, receipts, invoices, bank statements, and any documents you used to calculate deductions or report income. If the IRS audits you, they will almost always work within this three-year window.

However, three years is not a universal rule. The IRS extends the timeline in specific situations, and keeping records longer than required costs you nothing. The safest approach is to know which records fall into which category so you do not discard something you may need.

Key Takeaways

  • Keep most tax documents for three years from the date you file or the due date, whichever comes later.
  • If you underreport income by 25 percent or more, the IRS can audit you for six years instead of three.
  • Records related to property, investments, and retirement accounts should be kept for seven years or longer because they affect multiple tax years.
  • The IRS has no time limit to audit if you did not file a return or filed a fraudulent return, so keep those records indefinitely.
  • Digital copies, scanned documents, and photographs of receipts are acceptable as long as they are legible and complete.

When three years is not enough

The three-year rule has important exceptions. If you underreport your income by 25 percent or more, the IRS can go back six years instead of three. This applies to the income you actually reported on your return compared to what you should have reported. A single large unreported payment or a pattern of missed 1099 forms can trigger this longer window.

If you claim a loss from a worthless security or a bad debt, keep those records for seven years. The same applies to records tied to property you own — the cost basis of a home, rental property, or investment real estate should be kept for at least seven years after you sell it, because the IRS may question your gain or loss calculation years later.

For retirement accounts, investment accounts, and brokerage statements, the rule is simpler: keep them as long as the account exists, plus seven years after you close it. This covers cost basis disputes and ensures you have proof of contributions if the IRS questions your withdrawals or conversions.

Records related to home purchases and sales

If you own a home, keep all records tied to its purchase and sale indefinitely, or at minimum for seven years after you sell. This includes the purchase deed, closing statement, mortgage documents, and receipts for major improvements like a new roof, foundation work, or kitchen renovation. These records determine your cost basis, which directly affects how much tax you owe on the sale.

Keep records of home repairs and maintenance separately from improvements. Repairs (fixing a leaky roof) are not deductible and do not affect basis. Improvements (replacing the entire roof) do. The IRS may ask you to prove the difference, so having detailed receipts and contractor invoices matters.

What happens if you cannot find a record

If the IRS audits you and you cannot locate a receipt or document, you are not automatically penalized. The IRS understands that records get lost. You can reconstruct information using bank statements, credit card statements, or other documents that show the transaction occurred. A cancelled check or a charge on your credit card statement can serve as proof of a deduction even without the original receipt.

If you are audited and have no documentation at all for a claimed deduction, the IRS will disallow it. This is why keeping records matters — not because the IRS will punish you for losing them, but because you cannot prove the deduction without them. For large or unusual expenses, a photograph or a written note about what the expense was for can help if the original receipt vanishes.

Digital records and scanned documents

You do not need to keep paper originals. The IRS accepts digital copies, scanned documents, and photographs of receipts as long as they are legible, complete, and show all relevant information. A photo of a receipt taken with your phone is acceptable. A PDF scan of an invoice is acceptable. A spreadsheet you created to track mileage or business expenses is acceptable.

If you scan or photograph a document, make sure the image is clear enough to read all the details — the date, the amount, the vendor name, and what was purchased. Store digital copies in at least two locations (your computer and a cloud backup, for example) so you do not lose them to a hard drive failure. Many people use cloud storage services or document management apps specifically for this purpose.

Records you should never throw away

Certain documents should be kept indefinitely because they may be needed years or decades later. Keep all documents related to the purchase of a home or investment property for the life of your ownership plus seven years. Keep records of major medical expenses, especially if you claimed them as deductions, for at least seven years. Keep records of charitable donations, particularly large ones or donations of property, for seven years.

If you are self-employed or own a business, keep payroll records, invoices, and expense documentation for at least seven years. If you have a child, keep records of education expenses (tuition, books, student loan interest) for seven years in case the IRS questions your education credits. If you receive Social Security, keep your benefit statements and any correspondence from the Social Security Administration indefinitely, because these may affect your tax filing in retirement.

What the IRS actually audits

The IRS audits a small percentage of returns each year — roughly 0.4 percent overall, though the rate is higher for business returns and returns with high income. When they do audit, they typically focus on specific items: large deductions, business expenses, charitable donations, and income reported on 1099 forms. Having organized, complete records for these categories is far more important than keeping every receipt for every small purchase.

If you are audited, the IRS will tell you which tax year and which items they want to examine. You then have the opportunity to provide documentation. The three-year window gives you time to gather what you need. If you kept records beyond three years, you have even more protection.

Frequently Asked Questions

Can I throw away tax records after three years?

You can, but only if you are certain the three-year rule applies to that return. If you underreported income, claimed a loss on property, or have ongoing investments, the timeline is longer. When in doubt, keeping records for seven years is a safer choice and costs nothing.

Do I need to keep the original receipt or is a photo enough?

A photo or digital scan is enough as long as it is clear and shows all the details — the date, amount, vendor, and what was purchased. The IRS does not require original paper documents. Store digital copies in at least two places so you do not lose them.

What if I filed an amended return — does the three-year clock restart?

Yes. If you file an amended return (Form 1040-X), the three-year period starts over from the date you file the amendment, not from the original return date. Keep records for three years from the amendment date.

How long should I keep records if I am self-employed?

Keep business records for at least seven years. This includes invoices, receipts, payroll records, and expense documentation. Business records are audited more frequently than personal returns, and the IRS may go back further if they suspect underreported income.

What if I never filed a tax return — how long do I keep records?

If you did not file a return when you should have, the IRS has no time limit to assess taxes or penalties. Keep records indefinitely for any year you did not file. The same applies if you filed a fraudulent return — there is no statute of limitations.
