Keep tax records for at least three years after you file
The Internal Revenue Service (IRS) can audit your return for three years after you file it. That means you need to hold onto the documents that support what you reported — receipts, W-2 forms, 1099s, bank statements, and anything else you used to calculate your income and deductions. If you cannot produce these records when the IRS asks, you may lose deductions or owe additional tax.
Three years is the standard window. It applies to most people filing most returns in most years. But there are situations where you need to keep records longer, and understanding those situations protects you if an audit happens years down the road.
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 did not file a return or filed a fraudulent one, there is no time limit — keep records indefinitely.
- Keep the actual tax return itself (your 1040 and schedules) for at least seven years, even after the three-year audit window closes.
- Records related to property you own — home purchase documents, improvement receipts, rental records — should be kept for as long as you own the property plus three years after you sell it.
When the IRS can audit you for six years instead of three
If you underreported your gross income by 25 percent or more, the statute of limitations extends to six years. That means the IRS has six years from the filing date to open an audit. This is called the substantial underreporting rule.
Example: if your actual income was $100,000 but you reported $70,000, you underreported by 30 percent. The IRS could audit you up to six years later. In this case, keep all supporting documents for six years, not three.
You may not know whether your underreporting crossed the 25 percent threshold until an audit happens. To be safe, if you suspect you made a significant error on your return, keep records for six years.
Records with no time limit: fraud and unfiled returns
If you did not file a tax return at all, there is no statute of limitations. The IRS can audit you at any point. Similarly, if you filed a fraudulent return — meaning you intentionally misrepresented your income or deductions — the IRS has no time limit to pursue it.
In both cases, keep all relevant records indefinitely. This is rare, but it matters if it applies to you. If you have unfiled returns from years past, the best step is to file them now, even if you owe tax. Filing stops the clock and brings you under the standard three-year or six-year window instead of the unlimited one.
Keep your actual tax return for seven years
Beyond the three-year audit window, keep the tax return itself — your Form 1040 and all schedules and attachments — for at least seven years. This is longer than the IRS audit period, but it protects you in other situations.
You may need to show your return to a lender when you explore for a mortgage or business loan. You may need it to file an amended return or to claim a carryback or carryforward (like a business loss that carries to the next year). You may need it to prove your income to a government agency. Seven years covers most of these scenarios.
Property records: keep them as long as you own the property, plus three years after you sell
If you own a home, rental property, or investment real estate, keep all documents related to the purchase and any improvements you made. This includes the deed, the purchase agreement, receipts for repairs and renovations, and records of capital improvements (work that adds value to the property, not routine maintenance).
Keep these records for as long as you own the property. When you sell, keep them for three more years. The reason: the IRS may ask about your cost basis (what you paid for the property plus improvements) to verify the gain or loss you reported on the sale. If you cannot document your basis, you may owe tax on a larger gain than you actually made.
Example: you bought a house for $300,000, spent $50,000 on a new roof and kitchen, and sold it for $500,000. Your basis is $350,000, so your gain is $150,000. If you lose the improvement receipts, the IRS might say your basis is only $300,000, making your gain $200,000. Keep those receipts for the full holding period plus three years after sale.
Business and investment records: the same rules, applied to your business
If you are self-employed or own a business, keep all business records — income statements, expense receipts, payroll records, invoices, and bank statements — for at least three years. If you have employees, keep payroll records for at least four years.
For investment accounts, keep statements and trade confirmations for at least three years after you sell an investment. These documents prove your cost basis and holding period, which affect your tax bill when you report the sale.
If you claim depreciation on business property or rental property, keep the records that support the depreciation calculation for as long as you claim the deduction, plus three years after you stop.
Digital records and paper copies: both count
You do not have to keep paper copies. Digital records — PDFs, images, email confirmations, online bank statements, accounting software records — are acceptable to the IRS as long as they are clear and complete. Many people photograph receipts or read statements and store them in a folder on their computer or in cloud storage.
The key is that the record must be readable and show all the information you need to support your return. If you keep digital copies, make sure you have a backup. Hard drives fail, cloud accounts get deleted, and email inboxes get purged. A second copy — either another digital backup or a paper printout of the most important documents — is cheap insurance.
Frequently Asked Questions
What if I lost my records and the IRS audits me?
You can still defend your return without the original documents. You may be able to reconstruct records using bank statements, credit card statements, or other third-party documents. The IRS will work with you, but the burden is on you to prove what you reported. If you cannot, you may lose deductions or owe additional tax plus interest and penalties.
Do I need to keep receipts for every deduction?
For most deductions, yes — you need a receipt or other written proof. For charitable donations, you need a receipt from the charity. For medical expenses, you need receipts or invoices. For business expenses, you need receipts showing what you bought and when. The IRS does not require you to send receipts with your return, but you must have them if you are audited.
Can I throw away records after three years?
You can throw away supporting documents after three years if your return was filed correctly and you did not underreport income by 25 percent or more. But keep the tax return itself for seven years. If you are unsure whether you reported everything correctly, keep the supporting documents longer — it costs nothing to be cautious.
What about records for a return I amended?
Keep records for the amended return for three years from the date you filed the amendment, not from the date you filed the original return. If you filed an amended return in 2024 for a 2022 return, keep those records until 2027.
Do I need to keep records for returns I filed but did not owe tax?
Yes. Even if you had no tax liability, keep records for three years. The IRS may still audit to verify that your income and deductions were reported correctly. And you may need the return itself later to prove your income to a lender or government agency.
