How long you need to keep tax records depends on the type of record and whether the IRS ever audits you

The IRS requires you to keep most tax records for at least three years from the date you file your return or the return's due date, whichever is later. This three-year window covers the documents you used to prepare your tax return: receipts, invoices, bank statements, and proof of deductions. If you file early, the clock starts from the return's original due date, not the date you actually filed.

The three-year rule is the standard, but several situations require you to hold onto records longer. If you underreported your income by 25 percent or more, the IRS can audit you for six years instead of three. If you never filed a return or filed a fraudulent one, there is no time limit — the IRS can come after you indefinitely. For business records, rental property records, and records related to assets you still own, the rules are different and often longer.

Key Takeaways

  • Keep most tax documents for three years from the date you file or the return's due date, whichever comes later.
  • If you underreported income by 25 percent or more, keep records for six years because the audit window extends to six years.
  • For property you own — a house, rental property, or investments — keep records for as long as you own the asset plus three years after you sell it.
  • Business owners and self-employed people should keep payroll records, expense logs, and profit-and-loss statements for at least six years.

The three-year rule for most personal tax returns

The standard retention period is three years. This applies to W-2 forms, 1099 forms, receipts for charitable donations, medical expense records, mortgage interest statements, property tax records, and any other documentation you used to claim deductions or report income on your federal return.

The three-year clock does not start when you file. It starts from the return's due date — April 15 for most people, or October 15 if you filed an extension. If you file your 2023 return on February 1, 2024, the three-year window runs from April 15, 2023, not February 1, 2024. This means you should keep 2023 records until at least April 15, 2026.

State tax returns often have their own retention rules. Some states follow the federal three-year standard; others require four or five years. Check your state's tax agency website for the specific rule in your state, because you may need to keep records longer for state purposes than for federal purposes.

When you need to keep records for six years or longer

If you underreported your gross income by 25 percent or more, the IRS has six years to audit you instead of three. This means you must keep all supporting documents for six years. The IRS does not announce this in advance — you only learn about it if an audit actually begins. To be safe, if you know you reported income incorrectly or are unsure, keep records for six years.

If you never filed a return when you were supposed to, or if you filed a fraudulent return, there is no statute of limitations. The IRS can audit you at any time. In these cases, keep all records indefinitely or at least until you have resolved the issue with the IRS.

If you file an amended return (Form 1040-X), keep the amended return and all supporting documents for three years from the date you file the amendment, not from the original return's due date.

Records for property, investments, and assets you own

The three-year rule does not apply to property or long-term investments. Keep records for any house, rental property, business property, or investment account for as long as you own it, plus three years after you sell it. These records include the purchase price, improvements you made, the sale price, and the date of sale.

For a house you bought in 2015 and sold in 2024, keep the purchase documents, records of any renovations or repairs, and the sale documents until 2027 (three years after the 2024 sale). If you still own the house, keep the records indefinitely.

For stocks, mutual funds, bonds, and other investments, keep purchase confirmations, sale confirmations, and dividend statements for three years after you sell the investment. If you hold the investment long-term, keep records as long as you own it.

Business and self-employment records

If you are self-employed or own a business, the IRS requires you to keep payroll records, expense logs, invoices, receipts, and profit-and-loss statements for at least six years. This is longer than the three-year personal return rule because business records are more likely to be audited and the IRS needs more time to verify income and expenses.

Keep employment tax records (W-2s you issued, payroll tax deposits, quarterly filings) for at least four years after the date the tax becomes due or is paid, whichever is later. If you have employees, keep I-9 forms and payroll records for at least three years after hire or one year after termination, whichever is longer.

Rental property records follow the same rule as business records: keep them for six years. This includes lease agreements, rent payment records, repair and maintenance receipts, property tax statements, and mortgage statements.

What documents to keep and what you can discard

Keep these documents: Your filed tax return (or a copy), all W-2 and 1099 forms, receipts for deductions, bank and investment statements, mortgage statements, property tax records, charitable donation receipts, medical expense records, business expense logs, and any correspondence with the IRS.

You can discard these after three years (or the applicable period): Monthly utility bills (after you verify them on your annual statement), credit card statements (after reconciling them), pay stubs (after verifying them against your W-2), and receipts for small purchases under $75 that are not part of a larger deduction.

Keep receipts for large purchases, home improvements, and anything you claimed as a deduction. If you cannot produce a receipt, the IRS may disallow the deduction during an audit. For charitable donations over $250, you must have a written acknowledgment from the charity, not just a receipt.

How to store and organize tax records

Store records in a safe, dry place where they will not be damaged by water, fire, or mold. A filing cabinet, safe deposit box, or fireproof safe works well. Label each year's records clearly so you can find them quickly if you need them.

Digital copies are acceptable to the IRS. You can scan paper documents and store them on your computer, an external hard drive, or a cloud storage service. Make sure you keep backups — if your only copy is on a computer that crashes, you have lost the records. Some people keep both paper and digital copies for important documents like property deeds and investment confirmations.

Do not throw away records just because you filed your return. The three-year window is a minimum, not a deadline to discard. If you are unsure whether you need a document, keep it. The cost of storage is far less than the cost of not having a record if the IRS audits you.

Frequently Asked Questions

What if I lost my tax records and the IRS audits me?

Tell the IRS you no longer have the records. You can reconstruct some documents (bank statements from your bank, W-2s from your employer, 1099s from the issuer). For other expenses, you may be able to use bank or credit card statements to show the transaction occurred, even without the original receipt. The IRS may disallow deductions you cannot document, but you will not face penalties for losing records if you acted in good faith.

Do I need to keep receipts for everything I deduct?

For most deductions, yes. The IRS requires receipts or other proof. For charitable donations over $250, you need a written acknowledgment from the charity. For business meals and entertainment, you need the receipt plus a note about who you met and the business purpose. For small items under $75, some people keep a log instead of individual receipts, but a receipt is safer.

Can I throw away records after I file my return?

No. Wait at least three years from the return's due date before discarding records. If you underreported income, wait six years. For property and investments you still own, keep records indefinitely. For property you sold, keep records for three years after the sale.

Should I keep my tax returns themselves, or just the supporting documents?

Keep both. Keep a copy of your actual filed return (the Form 1040 and any schedules you submitted) along with all the receipts, statements, and other documents you used to prepare it. The return itself is proof of what you reported, and the supporting documents prove the return was accurate.

What if I filed an extension — does the three-year clock change?

No. The three-year period runs from the original due date (April 15), not from the extended due date (October 15). If you filed an extension for your 2023 return and filed on September 1, 2024, the three-year window still ends on April 15, 2026, not September 1, 2027.
