Keep tax records for at least three years after you file

The Internal Revenue Service (IRS) expects you to keep records that support what you reported on your tax return for a minimum of three years from the date you filed or the due date of the return, whichever is later. This three-year window is the standard timeframe for most situations and covers the documents the IRS is most likely to request during a routine audit.

However, three years is not a universal rule. The IRS can go back further if they suspect underreported income, and certain documents should be kept longer depending on what they are and what they prove. Understanding which records fall into which category prevents you from throwing away something you might need later.

Key Takeaways

  • Keep tax returns and supporting documents for at least three years from the filing date, which covers most IRS audits.
  • Keep records related to property, investments, and retirement accounts for seven years or longer, since gains and losses can be questioned years later.
  • Keep records for home purchases and improvements indefinitely, because the IRS can ask about your cost basis when you sell.
  • The IRS can request records going back six years if they believe you underreported income by 25 percent or more.
  • Organize records by tax year and keep them in a safe, accessible place—either physical files or scanned digital copies.

What the three-year rule covers

The three-year retention period applies to documents that directly support the numbers on your tax return: W-2 forms, 1099 forms, receipts for deductions, charitable donation records, medical expense documentation, and business expense logs. If you claimed a home office deduction, kept records of vehicle mileage, or deducted professional fees, those supporting documents should be kept for three years.

The clock starts on the date you actually filed your return, not the tax year itself. If you filed your 2023 return on April 15, 2024, the three-year window runs until April 15, 2027. If you filed an extension and submitted the return on October 15, 2024, the window extends to October 15, 2027. This distinction matters because filing late extends your record-keeping obligation.

When to keep records for six or seven years

The IRS can go back six years if they believe you left off more than 25 percent of your gross income. This is less common than a routine audit, but it happens. If you reported self-employment income, rental income, or investment income, keep those records for at least six years to be safe. The same applies if you claimed significant deductions that might draw scrutiny—large charitable donations, substantial business losses, or home office expenses.

Investment and brokerage records should be kept for seven years minimum. This includes statements showing what you paid for stocks, bonds, mutual funds, or other securities, as well as records of dividends and capital gains distributions. The IRS can question your cost basis (what you originally paid) years after you sell, and without documentation, you may end up paying tax on gains you cannot prove you already paid tax on.

Keep property and home records indefinitely

Documents related to real estate—purchase agreements, closing statements, receipts for home improvements, and property tax records—should be kept indefinitely. The IRS can ask about your cost basis in a home at any point, including years after you sell it. If you renovated a kitchen, added a deck, or replaced a roof, those receipts prove that the money you spent increased your basis in the property and reduced your taxable gain when you eventually sell.

This applies even if you sold the home decades ago. The IRS has no statute of limitations on questioning the cost basis of property, so keeping these records for life is the safest approach. Store them in a fireproof safe or scan them and back them up digitally.

Retirement account and education savings records

Keep statements from IRAs, 401(k)s, 403(b)s, and other retirement accounts for at least seven years. These records show your contributions, earnings, and withdrawals. If you took a distribution and reported it correctly on your tax return, the IRS may still ask years later whether the withdrawal was taxable or a return of basis. Documentation prevents disputes about whether you already paid tax on that money.

Education savings account records—529 plans, Coverdell ESAs, and records of education expenses—should also be kept for seven years. The IRS regularly audits education-related deductions and credits, and you will need to show what you actually spent and when.

How to organize and store tax records

Create a folder for each tax year and keep it in one place. Include the actual return you filed, all W-2s and 1099s, receipts for deductions, bank and credit card statements that show expenses, charitable donation letters, medical bills, property tax statements, and any correspondence with the IRS. Label everything clearly with the tax year.

You can keep records in physical form or scan them and store digital copies. If you scan, keep the originals for at least three years in case the IRS asks to see them. After that, you can shred paper records if you have clear digital backups. Use a cloud storage service with password protection or an external hard drive kept in a safe location. Do not rely on a single copy—back up digital records in two separate places.

What happens if you cannot find a record

If the IRS requests a document and you no longer have it, you are not automatically penalized. You can reconstruct records using bank statements, credit card statements, or other documentation that shows the transaction occurred. For example, if you lost a charitable donation receipt, a bank statement showing a check to the charity can serve as proof. For business expenses, you can use credit card statements or invoices from vendors.

The burden is on you to show that the deduction was legitimate, so reconstruction is harder than having the original receipt. This is another reason to keep records longer rather than shorter—the cost of storage is far less than the cost of losing a deduction or facing penalties if you cannot back up what you reported.

Frequently Asked Questions

Can I throw away tax records after three years?

Only if those records support deductions on a return that will not be questioned. For most people, three years is safe for routine deductions like standard charitable donations or work expenses. However, if you have investment income, rental property, or significant deductions, keep records longer. When in doubt, keep them—storage costs nothing compared to the risk.

Do I need to keep the original receipts or are photos okay?

Photos or scans are acceptable to the IRS as long as they are clear and show all relevant information: the date, the amount, what was purchased, and the vendor. Keep the originals for at least three years in case the IRS asks to see them. After that, you can discard the paper if your digital copies are backed up in two places.

What if I filed an amended return—does the three-year clock restart?

Yes. If you filed an amended return (Form 1040-X), the three-year period runs from the date you filed the amendment, not the original return. Keep records for three years from the amendment date. If you amended multiple times, the clock runs from the most recent amendment.

How long should I keep records for a business I no longer own?

Keep business records for at least seven years after you close the business. The IRS can audit prior years of business income and expenses, and you may need to show what you earned or deducted. This is especially important if you claimed depreciation on equipment or property—those records affect your basis when you sell the business.

Do I need to keep records if I use tax software or a CPA?

Yes. Your tax professional keeps a copy of your return, but you should keep your own copies of all supporting documents. If you are audited, the IRS will ask you for the records, not your CPA. Having your own organized files means you can respond quickly and completely.
