Keep tax records for at least three to seven years, depending on the type of document and whether you owe back taxes

The IRS can audit your return for three years after you file it. That is the baseline: keep everything related to that year's taxes for three years from the filing date. But some records need to stay longer. If you underreported income by 25 percent or more, the IRS has six years. If you never filed a return or filed a fraudulent one, there is no time limit at all. Property records, receipts for major home improvements, and documentation of losses carry their own timelines that often stretch beyond the standard three years.

The safest approach is to sort your records by category rather than by year. A receipt for a $500 office chair bought in 2019 might matter in 2024 if you are still depreciating it on your business taxes. A mortgage statement from 2015 could be relevant when you sell the house in 2025. Keeping records organized by what they prove—not just when you created them—makes it easier to know what to discard and what to hold.

Key Takeaways

  • Keep tax returns and supporting documents for at least three years from the date you filed, because the IRS can audit returns within that window.
  • If you reported income that was 25 percent or more below the actual amount, keep records for six years instead of three.
  • Property records, home improvement receipts, and investment statements should be kept for as long as you own the asset, plus three years after you sell it.
  • Business records, including mileage logs, receipts, and payroll documentation, follow the same three-year rule but may need to stay longer if you claim ongoing deductions.

The Three-Year Rule for Most Tax Documents

The three-year window is the IRS standard for routine audits. This covers your tax return itself, W-2 forms, 1099 forms, receipts, invoices, bank statements, and any other papers you used to calculate the numbers on your return. If you filed your 2022 return in April 2023, keep those records through April 2026. After that date, you can safely discard them—unless one of the longer timelines below applies to you.

The three years runs from the date you filed, not from December 31 of the tax year. If you filed early in January, your three-year window closes sooner than if you filed in October. This matters if you are trying to decide whether to keep a box of 2021 documents in late 2024—check your actual filing date on the return itself.

Keep the actual tax return (the 1040, 1040-SR, or whatever form you filed) for longer than three years if you can. A copy of your filed return is useful proof of income when you explore for a mortgage, a loan, or rental housing. Many lenders ask for the last two years of returns. Keeping them indefinitely costs nothing and solves problems later.

When to Keep Records for Six Years or Longer

The IRS extends the audit window to six years if you underreported your gross income by 25 percent or more. This is a high bar—if you reported $40,000 in income when you actually earned $53,000 or more, you hit it. The six-year clock starts from the filing date, just like the three-year rule. If you are unsure whether you crossed this threshold, keep the records for six years to be safe.

There is no statute of limitations if you never filed a return at all or if you filed a fraudulent return. The IRS can come after you indefinitely. If either of these applies to you, keep all records related to those years permanently or until you have resolved the situation with the IRS.

Property records and home improvement receipts should stay for as long as you own the property, then for three more years after you sell it. The reason: when you sell a house, you report the gain or loss, and the IRS may ask to see the original purchase price, closing documents, and receipts for improvements that raised the property's value. Keep the deed, the original closing statement, and any receipts for major work (roof, foundation, kitchen renovation) in a separate file labeled by property address.

Business Records and Depreciation Documents

If you are self-employed or own a business, the three-year rule still applies to your tax return and the receipts that support it. But depreciation changes the timeline. If you depreciate an asset over five years, you need to keep the receipt and proof of purchase for those five years plus three more—eight years total. The same logic applies to any asset you are still deducting on your current return, even if you bought it years ago.

Mileage logs, vehicle maintenance records, and fuel receipts for a business vehicle should be kept for three years after the year in which you last claimed the mileage deduction. If you claimed business mileage in 2023, keep those logs through 2026. Once you stop using the vehicle for business, the three-year clock starts from the last year you deducted it.

Payroll records, if you employ people, must be kept for at least three years. The Department of Labor recommends keeping them for four years, so three years is the IRS minimum but not the only standard that applies. If you are ever audited on payroll taxes, the auditor will ask for these records, so treat them as a separate category from your personal tax documents.

Investment and Brokerage Records

Keep statements from your brokerage account, mutual fund company, or investment advisor for at least three years after you sell the investment. The reason is capital gains tax: when you sell a stock, a bond, or a fund, you report the gain or loss, and the IRS may ask to see the original purchase price and date. A brokerage statement from the year you bought proves both. Keep the statement from the sale year as well, because it shows the proceeds and the date of sale.

If you inherited investments, keep the statement from the date of inheritance (which establishes your "stepped-up basis") for as long as you own the investment, plus three years after you sell. Inherited assets get special tax treatment, and the IRS takes this seriously.

Dividend reinvestment statements and statements showing splits or mergers are part of your cost basis for the investment. If you own mutual funds that reinvest dividends, keep those statements for the life of the investment plus three years after you sell, because they affect how much gain you owe tax on.

Medical, Charitable, and Deduction-Related Records

If you itemize deductions on your tax return, keep the receipts and statements that prove those deductions for three years. This includes medical expense receipts, charitable donation receipts, property tax statements, and mortgage interest statements (which your lender sends as a 1098 form). The IRS does not always ask for these, but when it does, you need them.

Charitable donations of non-cash items (clothing, furniture, vehicles) require a receipt from the charity or a written statement of what you gave and its estimated value. Keep these for three years. If you donate a car, the charity will send you a form showing the sale price or your claimed value—keep that form for three years.

Medical records that support deductions (receipts for prescriptions, therapy, dental work, glasses) should be kept for three years. If you are claiming a dependent with significant medical expenses, keep those records separately and label them clearly by year and person.

How to Organize and Store Tax Records

The simplest system is a folder or box for each tax year, labeled clearly with the year. Inside, group documents by category: W-2s and 1099s together, receipts by type (medical, charitable, business), bank statements, and the final tax return. This takes 30 minutes to set up and makes it obvious what you have.

For records that span multiple years—like property documents or ongoing business expenses—create a separate file by property address or business category. A file labeled "House at 123 Main Street" can hold the deed, closing statement, and improvement receipts all in one place, regardless of what year they came from.

Digital storage is fine. Scan receipts and statements, organize them in folders on your computer or cloud storage, and back them up. The IRS accepts digital records as proof. If you use accounting software like QuickBooks or TurboTax, those programs store records digitally and can export them if you need to show them to an auditor.

Do not throw away records until you are certain the retention period has passed. If you filed your 2021 return in April 2022, the three-year window closes in April 2025. Mark that date on a calendar or in a note on the folder so you know when it is safe to discard.

Frequently Asked Questions

What if I filed my taxes late—does the three years start from when I filed or from the tax important date?

The three years starts from the date you actually filed, not from the April 15 important date. If you filed your 2022 return in October 2023, your three-year window closes in October 2026. The IRS counts from the filing date shown on your return or the postmark on the envelope if you mailed it.

Do I need to keep receipts if I use accounting software that stores everything?

Yes, keep the original receipts or scanned copies. Accounting software is a record of what you entered, not proof of the transaction itself. If the IRS audits you, they want to see the actual receipt—the one from the store or vendor—not just your entry in the software. Scan them and store the digital files alongside your software records.

Can I throw away records after three years if I am self-employed?

Only if you are not still deducting any assets from that year. If you bought equipment in 2021 and are still depreciating it in 2024, keep the 2021 receipt until you finish depreciating it, then keep it for three more years. Once you have fully depreciated an asset and stopped deducting it, the three-year rule applies to that receipt.

What should I do with old tax returns I no longer need?

Shred them or burn them if they contain sensitive information like your Social Security number or bank account details. Do not just throw them in the trash. If you are keeping digital copies, delete the files securely using a file-shredding tool rather than just moving them to the trash folder.

Do I need to keep receipts for small purchases under $75?

The IRS does not have a dollar threshold for keeping receipts. Any receipt that supports a deduction on your tax return should be kept for three years, regardless of the amount. A $20 receipt for office supplies is just as important as a $500 one if you claimed it as a business expense.
