How Long to Keep Tax Records: Plain-English Rules
Updated October 26, 2026
The basic 3-year rule
The IRS generally has three years from the date you filed, or the due date, to review a return and assess more tax. That is why 3 years is the usual minimum. Keep the return itself, plus the receipts and forms that support it, for that long.
The cases that need 6 or 7 years
The period is longer in some situations. If you left out more than 25 percent of the income shown on your return, the IRS has six years to assess tax. If you claim a loss from worthless securities or a bad debt deduction, keep the records for seven years.
These rules are easy to miss. A large unreported 1099 or a claim for a worthless investment is the usual reason people need older records.

Keeping records for each tax year
Make a folder for each tax year and put everything in it as you go. Include the signed return, the forms that feed it, and the support for each deduction or credit. Do not wait until April to sort receipts. A short monthly check keeps the folder complete and makes a notice much less stressful.
Label digital files with the year and the type of record, such as the year plus Schedule C expenses or the year plus mileage log. Clear names save hours if the IRS asks for documents or if you switch tax preparers.
Proof of income and proof of payment
Keep proof of income, such as deposit slips, bank statements, and copies of the forms you received. Keep proof of deductions, such as receipts, invoices, and card statements that show a payment. A bank statement alone may not prove what you bought, so keep the matching receipt or invoice when you can.
For estimated tax payments, keep the confirmation for each payment. For retirement contributions, keep the statements that show the amount and date. These small records answer most questions an IRS letter raises.
Property and home records
Keep records for things you own, such as a home, rental property, or a business asset, for as long as you own them and for at least 3 years after you sell or dispose of them. You need these records to figure your cost basis, depreciation, and gain or loss when you sell.
Keep closing statements, improvement receipts, and depreciation schedules together in one folder.
What to keep, and what to shred
Keep copies of your returns, W-2s, 1099s, receipts for deductions, mileage logs, bank and card statements that show income or expenses, and records of estimated tax payments. Keep notices and letters from the IRS and your state until the matter is closed.
Do not shred records early. Wait until the period for the year has passed and no notice is open. When you do shred, use a cross-cut shredder for anything with your Social Security number or bank details, so identity thieves cannot use it.
When a notice arrives
If you get an IRS letter about a past year, keep it with that year's folder and do not throw it away. Note the date on the letter and the response deadline. Keeping the notice and the records together lets you or a tax professional respond quickly and accurately. Keep these papers longer than the general rule if the letter is still open.
FAQ
What is the minimum time to keep tax records?
Generally at least 3 years from the date you filed or the due date, whichever is later.
How long if I did not report some income?
Six years if you left out more than 25 percent of the gross income shown on your return.
Should I keep records for my house?
Yes. Keep records for as long as you own it and for at least 3 years after you sell, so you can prove your cost basis.
Are digital copies acceptable?
Yes, as long as they are complete, readable, and backed up.
What about a year I never filed a return?
The IRS period to assess tax generally does not start until a return is filed. Keep records for years you have not filed until you file that return and the usual period passes.
Why keep the signed return for a long time?
Many people keep copies of signed returns for years because lenders and other offices often ask for them as proof of income. Keeping the return longer costs little.
