Keep tax papers for at least three years after you file

The Internal Revenue Service (IRS) generally has three years from the date you file a return to audit it. This means you should keep all documents that support what you reported — receipts, W-2s, 1099s, bank statements, cancelled checks, invoices, mileage logs, and anything else you used to calculate income or deductions — for a minimum of three years.

That three-year window is the baseline. It extends in specific situations, and some records are worth keeping longer regardless of the rules. Understanding when and why the timeline changes helps you avoid throwing away something you might need later.

Key Takeaways

  • The IRS can audit your return for three years after you file, so keep all supporting documents for at least that long.
  • If you underreported income by 25 percent or more, the IRS has six years to audit you, so keep records for six years in that case.
  • If you never filed a return or filed a fraudulent one, there is no time limit — keep those records indefinitely.
  • Records related to property you own (home, rental property, investments) should be kept for at least three years after you sell, because the gain or loss calculation depends on the original purchase documents.

When the three-year rule extends to six years

If you reported less income than you actually earned, and the underreported amount is 25 percent or more of the gross income you did report, the IRS can go back six years instead of three. This is called the "substantial understatement" rule.

Example: You reported $40,000 in income but actually earned $60,000. The difference is $20,000, which is 50 percent of what you reported. The IRS can audit you for six years. If you reported $40,000 but earned $50,000 (a $10,000 difference, or 25 percent), you are at the boundary — some auditors may treat this as six years, others as three. The safest approach is to keep records for six years if you know you underreported.

You should also keep records for six years if you claimed a loss on a business or rental property, because the IRS scrutinizes these claims more closely and may want to verify your expenses in detail.

No time limit: fraud, unfiled returns, and missing records

If you never filed a tax return for a year, there is no statute of limitations. The IRS can pursue you indefinitely. Keep all documents related to any year you did not file.

If you filed a fraudulent return — meaning you knowingly reported false information — there is also no time limit. The IRS can audit you at any point. This is rare in practice, but it means you cannot safely discard records from a year you know involved fraud.

If you cannot locate a document the IRS requests during an audit, you will need to reconstruct it or explain why it is missing. Keeping records longer than the minimum protects you if the IRS comes back years later with questions.

Property and investment records: keep longer than three years

Records tied to property ownership should be kept for at least three years after you sell the property, not three years after you buy it. This is because the IRS will want to verify your cost basis (what you paid) and any improvements you made, in order to calculate your capital gain or loss.

For a home: Keep the purchase deed, closing statement, receipts for major renovations (roof, foundation, kitchen remodel), and records of any casualty losses or insurance payouts. If you sell in year 10, keep these documents through year 13.

For rental property or investment real estate: Keep purchase documents, improvement receipts, depreciation schedules, and records of any casualty or theft losses for at least three years after the sale. The IRS may also ask about depreciation recapture, which requires proof of what you claimed in prior years.

For stocks, mutual funds, and other investments: Keep purchase confirmations, sale confirmations, and dividend statements for at least three years after you sell. If you inherited investments, keep the valuation statement from the date of death, because that becomes your cost basis.

Records to keep indefinitely

Some documents are worth keeping permanently, even though the IRS does not require it. These include the deed to your home (until you sell and three years after), the original purchase and sale agreement for any real estate, records of major home improvements, and documentation of any large gifts or inheritances you received.

Keep permanent records of any year in which you had self-employment income, because the IRS can sometimes go back further on business-related audits. If you own a business, keep all business tax returns and supporting records for at least seven years, even if the three-year rule would normally apply.

If you claimed a home office deduction, keep the documentation (photos, measurements, square footage calculations) for at least six years. If you claimed education credits or deductions, keep tuition bills and enrollment records for at least six years.

How to organize and store tax records

Create a folder for each tax year. Inside, group documents by category: income (W-2s, 1099s, K-1s), deductions (receipts, invoices, mileage logs), property records (deeds, closing statements, improvement receipts), and any correspondence with the IRS.

Store originals in a safe place — a filing cabinet, safe deposit box, or home safe. You can also scan documents and keep digital copies, but keep the originals for at least three years. If the IRS audits you, they may ask to see original documents, not photocopies.

Label each folder clearly with the tax year. If you use tax software or work with a tax preparer, ask them to keep a copy of your return and supporting documents. Many tax preparers keep records for seven years as a matter of practice.

What happens if you throw away records too early

If the IRS audits you and you cannot produce a receipt or document they request, you are not automatically penalized. However, you will have to reconstruct the expense or deduction using other evidence — bank statements, credit card statements, cancelled checks, or written explanations. This is harder and takes longer than simply producing the original document.

If you cannot reconstruct the expense convincingly, the IRS may disallow the deduction entirely. This can result in additional tax owed, plus interest and penalties. Keeping records for the full three years (or six years, or longer) is much simpler than trying to recreate them years later.

Frequently Asked Questions

Can I throw away tax records after three years?

Yes, if you reported all your income correctly and did not claim any unusual deductions. However, if you underreported income by 25 percent or more, or if you claimed a business loss or rental property deduction, keep records for six years. For property you own, keep records for three years after you sell, not three years after you file.

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

A photo or scan is acceptable for your own records and for most audits. However, the IRS may ask to see the original during an audit, so keep originals for at least three years. After that, a digital copy is usually sufficient if you need to reference it later.

What if I filed an amended return?

Keep records for three years from the date you filed the amended return, not the original return. The three-year window restarts when you amend. If you amended multiple times, the clock runs from the most recent amendment.

How long should I keep records if I am self-employed?

Keep business tax returns, profit-and-loss statements, and all supporting receipts and invoices for at least seven years. The IRS can sometimes go back further on business audits than on individual returns, so the longer timeline is safer.

Do I need to keep records for years I did not owe taxes?

Yes. Even if you had no tax liability, keep records for three years. The IRS may still want to verify that you reported all income correctly, and you may need the records to prove you were not required to file or owed nothing.
