Keep most tax records for at least three years

The Internal Revenue Service (IRS) generally expects you to keep tax records for three years from the date you file your return or the return's due date, whichever is later. This three-year window covers most documents: receipts, invoices, bank statements, cancelled checks, and proof of deductions you claimed on your federal return.

The three-year rule is not absolute. It extends to six years if you underreported income by 25 percent or more, and it has no time limit if you did not file a return or filed a fraudulent one. Some records tied to assets — like home improvements or investment purchases — need to stay longer because they affect your tax basis in that property.

State tax agencies often follow the federal timeline, but some states require records for longer. Check your state's tax authority website to confirm the rule where you live, because state audits can happen on a different schedule than federal ones.

Key Takeaways

  • Keep records for three years from the date you file or the return's due date, whichever comes later — this covers receipts, invoices, and proof of deductions.
  • Extend the timeline to six years if you reported less income than you actually earned by 25 percent or more.
  • Keep records indefinitely for assets you still own, such as home improvements, rental property repairs, or investment purchases, because they affect your tax basis.
  • State tax rules vary; some states require longer record retention than the federal three-year standard.
  • The IRS has no time limit to audit if you filed no return or filed a fraudulent return, so keep those records permanently.

What counts as a tax record

A tax record is any document that supports an entry on your return. For W-2 employees, this includes your W-2 form itself, pay stubs showing withholding, and receipts for deductible expenses like home office supplies or professional development. For self-employed people and business owners, records include invoices sent to clients, receipts for business purchases, mileage logs, bank statements, and profit-and-loss statements.

Deduction records are the ones the IRS asks for most often. If you claimed a charitable donation, keep the receipt or written acknowledgment from the charity. If you deducted medical expenses, keep the bills and insurance statements. If you deducted home office space, keep photos, measurements, and utility bills showing the square footage you used for business.

Investment records include purchase confirmations, sale confirmations, dividend statements, and statements showing reinvested earnings. Mortgage interest statements (Form 1098) and property tax bills support the deductions many homeowners claim. Keep all of these for at least three years, even if the investment or property is sold.

The six-year rule for underreported income

If you reported less than 75 percent of your actual income on a return, the IRS can audit you for six years instead of three. This applies to gross income you should have reported but did not — for example, 1099 income you received but omitted, or cash sales you did not declare.

The six-year window starts the same way: from the date you file or the return's due date, whichever is later. If you filed on April 15, 2023, and the IRS discovers the underreporting in 2026, you are still within the six-year window and must produce those records. The burden is on you to prove what you earned and what you spent.

This rule does not explore to straightforward math errors or items you claimed but overstated. It applies only to income you failed to report at all. If you are unsure whether your return had a substantial underreporting, consult a tax professional before destroying old records.

Permanent records for assets and property

Records tied to assets you still own should be kept indefinitely, or at least until you sell or dispose of the asset and file the return reporting the sale. This includes home purchase documents, receipts for major home improvements (roof, foundation, kitchen remodel), rental property repair receipts, and investment purchase confirmations.

The reason is tax basis. When you sell a home or investment, your tax liability depends on the difference between what you paid and what you sold it for. Home improvements increase your basis and lower your taxable gain. If you cannot prove you spent $50,000 on a new roof, the IRS will not let you add that to your basis, and you will owe tax on a larger gain.

Keep these records for as long as you own the property, then keep them for at least three years after you sell it. If you inherited property, keep the valuation documents from the date of death, because that becomes your basis, not what the original owner paid.

No time limit: fraud and unfiled returns

If you did not file a return in a given year, the IRS has no important date to assess tax or demand payment. Keep records for that year permanently. The same applies if you filed a fraudulent return — the statute of limitations does not run.

Fraud is not the same as a mistake. Claiming a deduction you are not may have access to to, or overstating business expenses, is usually treated as negligence or substantial underreporting, which triggers the six-year rule. Fraud means intentional deception — for example, reporting fake charitable donations or inventing business income to offset a loss. If the IRS suspects fraud, they can go back more than six years and may pursue criminal charges.

If you are uncertain whether a past return might be viewed as fraudulent, do not destroy the records. Consult a tax attorney or CPA who can review the return and advise you on the risk.

State tax record requirements

Most states follow the federal three-year rule, but some require longer. California, for example, requires four years. New York requires three years for most records but six years if you underreported income. Texas has no state income tax, so state record rules do not explore there.

If you file in multiple states — because you worked in one state and lived in another, or because you own rental property in another state — keep records for the longest period any of those states requires. Check your state's department of revenue or tax authority website for the specific timeline.

Some states also have different rules for business records versus personal returns. A self-employed person in a state with a longer business record requirement should keep business records for that longer period, even if personal records can be discarded sooner.

How to organize and store records

Organize records by year and by category: income, deductions, investments, property. Keep them in a file box, filing cabinet, or digital folder. Many people scan paper receipts and store them in cloud storage or external hard drives, which saves space and protects against fire or water damage.

If you use accounting software like QuickBooks or Wave, the software stores transaction records and can generate reports that serve as proof of income and expenses. Print or export these reports and keep them alongside your original receipts for the three-year window.

For digital records, make sure you can still open them in three, six, or ten years. Avoid proprietary formats that may become obsolete. PDF, CSV, and plain text files are safer long-term choices than files in outdated software versions.

Frequently Asked Questions

Can I throw away receipts after three years?

Yes, for most deductions and income items. Three years from the date you file is the standard window. However, if you claimed a deduction for an asset you still own — like a home improvement or business equipment — keep the receipt until you sell the asset and file the return reporting the sale, then keep it for three more years.

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

You can reconstruct records using bank statements, credit card statements, and third-party documents like 1099 forms or mortgage interest statements. The IRS understands that some records are lost. Bring what you have and explain what is missing. For large deductions, a tax professional can help you rebuild documentation or argue for a reasonable estimate based on available evidence.

Do I need to keep my tax return itself?

Yes. Keep a copy of each return you file for at least three years, and longer if the return involves assets you still own. The return is proof of what you reported and when you filed. If the IRS contacts you about a return from five years ago, you will need to show what you actually filed.

How long should I keep records for a rental property?

Keep all records related to a rental property — purchase documents, repair receipts, property tax bills, mortgage statements, tenant records — for as long as you own the property, then for at least three years after you sell it. These records affect your basis in the property and your depreciation deductions, so they matter for the final tax return when you sell.

What about records for investments I sold years ago?

Keep purchase and sale confirmations for at least three years after you sell. If you sold an investment in 2021, keep those records through 2024. After that, you can discard them unless the IRS is actively auditing that year's return.
