How long you should keep tax returns

Keep your federal tax return and all supporting documents for at least three years from the date you filed or the due date, whichever is later. The IRS can audit your return during this window, and you will need those documents to prove what you reported. If you owe back taxes or the IRS suspects underreported income, they can go back six years. In rare cases involving fraud, there is no time limit.

State tax returns follow similar rules, though some states require you to keep records longer than the federal requirement. Check your state's tax authority website for the specific number of years your state demands. Many people keep federal and state documents together for simplicity, using the longer of the two timeframes.

The three-year baseline applies to most filers. However, if you claimed a loss carryback or filed an amended return, the clock restarts from when you filed that amended return. Keep track of when you actually mailed or e-filed your return, not just when the tax year ended.

Key Takeaways

  • Keep your filed tax return and receipts, invoices, and bank statements that support it for at least three years from the filing date.
  • If the IRS suspects underreported income, they can audit back six years, so keeping records longer than three years provides extra protection.
  • State tax returns often have their own retention requirements, which may be longer than the federal three-year rule.
  • Amended returns restart the clock, so keep the amended return and its supporting documents for three years from the date you filed the amendment.
  • After the retention period ends, you can shred paper documents or delete digital files, but keep a copy of the actual return itself indefinitely for your records.

What documents to keep with your return

Do not keep just the return itself. Store everything you used to fill it out: W-2 forms from employers, 1099 forms for freelance income or investments, receipts for charitable donations, medical expense records, mortgage interest statements, property tax bills, and business expense documentation. If you claimed deductions, keep the receipts or invoices that prove you spent that money. If you reported investment income, keep the brokerage statements showing the transactions.

For business owners and self-employed filers, the list is longer. Keep records of all income sources, a log of business mileage if you claimed mileage deductions, receipts for equipment and supplies, payroll records if you had employees, and bank statements showing deposits and expenses. The IRS is more likely to audit business returns, and auditors will ask to see these records in detail.

Digital copies count. If you received a W-2 or 1099 electronically, save the PDF or email it to yourself and store it in a folder labeled by year. If you took photos of receipts, organize them by category and year. The format does not matter as long as you can produce the document if asked.

How long to keep records if you are self-employed or own a business

Self-employed filers and business owners should keep records for seven years instead of three. The IRS scrutinizes business returns more closely, and the longer retention period protects you if an audit happens years after you filed. This includes income records, expense receipts, payroll documentation, and bank statements related to the business.

If your business has employees, keep payroll records and tax forms (W-2s, 941s, 940s) for at least seven years as well. The Department of Labor may also request these records, and the seven-year window covers both federal and most state labor audits. If you have a retirement plan for your business, keep those records for seven years too.

The seven-year rule also applies if you claimed a home office deduction, depreciation on equipment, or losses that you carried forward to future years. These items attract IRS attention, and longer documentation protects you.

When you can safely discard old returns and documents

After three years have passed (or six years for business owners, or seven years if self-employed), you can shred paper documents or delete digital files. However, keep a copy of the actual return itself—the form you signed and filed—indefinitely. This serves as proof that you filed in that year and what you reported, which can matter for Social Security credits, mortgage applications, or background checks years later.

Before you throw anything away, make sure the statute of limitations has truly expired. Count three full years from the date you filed, not from April 15. If you filed on April 10, 2021, you can discard supporting documents on April 10, 2024. If you filed an amended return in 2022, the clock restarted, and you count three years from that amended filing date instead.

Use a shredder for paper documents containing Social Security numbers, account numbers, or other sensitive information. Do not just toss them in the trash. For digital files, delete them from your computer and empty the recycle bin, or use file-deletion software that overwrites the data.

Special situations that change the retention timeline

If you filed a return showing a loss, keep those records longer. The IRS may question whether the loss was legitimate, and you will need documentation to defend it. The same applies if you claimed a large deduction relative to your income—auditors notice unusual patterns.

If you are involved in a lawsuit, tax dispute, or bankruptcy, do not discard any tax documents until the case is resolved and any appeal period has ended. Your attorney or accountant will tell you when it is safe to destroy them. Some disputes can take years to settle, and discarding evidence during an active case can create serious legal problems.

If you received a notice from the IRS saying they are examining your return, stop discarding documents when ready. Keep everything related to that return indefinitely until the examination is closed in writing. The IRS will tell you when you can safely discard the records.

Organizing documents so you can find them later

Create a folder for each tax year, either physical or digital. Label it clearly with the year: "2023 Tax Documents" or "2024 Tax Return." Inside, organize by category: W-2s and 1099s in one section, charitable donations in another, medical expenses in another, and so on. This makes it much faster to locate a specific receipt if the IRS asks about it.

If you file electronically, read and save a copy of your filed return as a PDF. Do not rely on the tax software's online portal, which may disappear or become inaccessible years later. Store the PDF in your tax year folder alongside the supporting documents.

For digital receipts and statements, use a consistent naming convention. Instead of "receipt.pdf," name it "2024-03-15_Office_Depot_Supplies.pdf" so you can search by date or vendor. Store everything in one location—a folder on your computer, a cloud service like Google Drive, or an external hard drive—so you know exactly where to look when you need something.

Frequently Asked Questions

Can I throw away my tax return after three years?

You can discard the supporting documents (receipts, statements, forms) after three years, but keep a copy of the actual return itself indefinitely. The return is proof you filed and what you reported, which matters for future reference even if the IRS cannot audit you anymore.

What if I never received a copy of my filed return?

If you filed electronically, log into the IRS website or your tax software account and read a copy of the confirmation or transcript. If you filed on paper, contact the IRS at 800-829-1040 and request a copy. Keep that copy with your other tax documents for your records.

Do I need to keep receipts if I took the standard deduction?

No. If you took the standard deduction instead of itemizing, you do not need to keep receipts for individual deductions. However, keep records of any income you reported, such as W-2s, 1099s, and bank statements showing deposits, because those are what the IRS verifies.

How should I store old tax documents—paper or digital?

Either works. Digital storage takes less space and is easier to search, but make sure you back it up to an external drive or cloud service in case your computer fails. Paper storage is fine if you have the space and keep it organized. Many people scan important documents and keep both a digital and paper copy for the first few years, then discard the paper once they are confident the digital version is find.

What happens if I throw away documents and then get audited?

If the IRS audits you and you cannot produce the supporting documents, the IRS can disallow the deductions or income you claimed. You may owe back taxes, interest, and penalties. This is why keeping records for at least three years is important—it protects you if an audit happens during that window.
