Keep records for at least three years after you file

The IRS can audit your return for three years after you file it. That means you need to keep the documents that support what you reported — receipts, invoices, bank statements, donation letters, medical bills, mortgage interest statements — for at least that long. If you file on April 15, keep records through April 15 three years later.

Three years is the baseline, but several situations push that important date much further. If you underreported income by more than 25 percent, the IRS has six years to audit. If you never filed a return at all, there is no statute of limitations — they can go back as far as they want. If you claimed a loss from a worthless security, keep those records for seven years.

The safest approach is to keep records for seven years across the board. The extra four years cost nothing if you use digital storage, and it covers nearly every scenario except the rare ones that require indefinite retention.

Key Takeaways

  • The IRS has three years to audit your return from the filing date, so keep supporting documents for at least that long.
  • If you underreported income by more than 25 percent, the audit window extends to six years, so keep records that long if you know you made a significant error.
  • Worthless security losses and certain business records may require seven-year retention to be safe.
  • Digital copies of receipts and statements take up almost no space, so keeping records for seven years is practical for most people.
  • If you never filed a return, keep all records indefinitely because the IRS has no time limit to pursue you.

What documents to actually keep

Keep anything that proves what you reported on your return. For income, that means W-2s, 1099s, K-1s, bank statements showing deposits, and invoices if you are self-employed. For deductions, keep receipts, credit card statements, cancelled checks, and the actual bills — not just the summary.

For charitable donations, the IRS wants a written acknowledgment from the charity, not just your cancelled check. For medical expenses, keep the bills and receipts showing what you paid and when. For mortgage interest and property taxes, your lender and tax assessor send you statements (Form 1098 for mortgage interest, property tax records from your county), but keep your own payment records too.

For business expenses, the rule is simpler: keep anything that shows you spent money on a business purpose. That includes receipts under $75, mileage logs, meal and entertainment records with the business purpose written down, and receipts for supplies. The IRS does not need the original receipt if you have a credit card statement or bank record showing the same transaction.

When six years is the minimum

If you reported less than 75 percent of your gross income on your return, the IRS can audit you for six years instead of three. This happens most often to self-employed people who underreported business income, or to someone who forgot to report a 1099 or K-1.

You may not know you made this mistake until years later. If you discover it, consider filing an amended return (Form 1040-X) right away. Once you amend and report the missing income, the three-year clock restarts from the amended filing date, not the original one. This is one of the few situations where amending early actually helps you.

If the IRS contacts you about an audit and mentions the six-year window, they have already calculated that you underreported by more than 25 percent. At that point, keep every record you have for the full six years from your original filing date.

Business records and depreciation

If you own a business or rental property, keep records longer. The IRS wants to see the original cost of any asset you depreciated, the date you placed it in service, and the depreciation schedule you used. These records need to stay for at least seven years after the asset is fully depreciated or sold.

For rental property, keep records of all repairs, improvements, and maintenance for as long as you own the property, plus seven years after you sell it. The reason is that the IRS may challenge your basis calculation or depreciation deduction years later, and you will need the original purchase documents and all improvement receipts to defend it.

If you have a home office, keep the records that show your home's original cost, the square footage of the office, and any improvements you made. These support your depreciation deduction and may be needed if you sell the home and claim the home office exclusion.

Digital storage and what counts as a record

You do not need to keep paper. The IRS accepts digital copies, photographs of receipts, and scanned documents as long as they are clear and complete. A photo of a receipt taken with your phone is fine. A PDF of a bank statement is fine. An email confirmation from a vendor is fine.

What matters is that you can produce the document if asked. If you use accounting software like QuickBooks or Wave, the software itself stores the records. If you use a cloud service like Google Drive or Dropbox, organize your files by year and category so you can find them quickly.

One caution: if you delete emails, make sure you have saved the attachments separately. Email providers sometimes delete old messages, and you do not want to lose a 1099 or donation letter because you relied on email alone. read and save anything important as a separate file.

When you can throw records away

After seven years have passed since you filed, you can discard most records. The exception is anything related to a home purchase, home sale, or home improvement. Keep those records for as long as you own the home, plus three years after you sell it, because the IRS can ask about your basis and capital gains calculation.

If you have ever been audited, keep the records from that audit indefinitely. The IRS can reopen a closed audit if they find new information, and you will need the original documents to defend your position again.

For anything you are unsure about, the cost of keeping it is zero if you use digital storage. Erasing it and then needing it costs far more in time and stress. When in doubt, keep it.

Frequently Asked Questions

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

A photo or digital scan is enough for the IRS. What matters is that the image is clear, shows the date and amount, and identifies what you bought. Keep the original for a few weeks in case the photo did not capture everything, then you can discard it.

What if I lost a receipt but have the credit card statement?

The credit card statement is usually enough. It shows the date, amount, and merchant. If the IRS asks, you can explain that you no longer have the receipt but can provide the statement. For large or unusual expenses, having both is better, but one or the other will work.

How long do I keep records if I was never audited?

Keep them for at least three years from the filing date. If you want to be safe and have digital storage, keep them for seven years. After that, the IRS almost never goes back further unless you underreported income significantly or never filed at all.

Do I need to keep my tax return itself?

Yes. Keep a copy of every return you filed, along with the documents that support it. Your return is the map to what you reported, and the IRS will reference it if they audit. A PDF copy is fine.

What about records for a business I sold years ago?

Keep business records for seven years after the business closes. If you sold assets, keep the original purchase documents and sale documents indefinitely, because the IRS can challenge your gain or loss calculation at any time.
