Keep federal tax returns for at least three years
The Internal Revenue Service (IRS) can examine your tax return for three years after you file it. This is the standard period for an audit. Because of this, you should keep your filed tax return, the documents you used to prepare it, and proof that you paid what you owed for at least three years from the date you filed.
Three years is the minimum, not the ideal. If you underreported your income by 25 percent or more, the IRS can go back six years. If you did not file a return at all, there is no time limit — the IRS can examine any year you did not file. Keeping records for longer than three years costs you nothing and protects you if questions arise later.
The clock starts when you file, not when the tax year ends. If you file your 2023 return in April 2024, the three-year window closes in April 2027. If you file late, the window opens from your actual filing date.
Key Takeaways
- The IRS can audit your return for three years after you file it, so keep your return and all supporting documents for at least that long.
- The audit window extends to six years if you underreported income by 25 percent or more, and has no limit if you did not file at all.
- Supporting documents include receipts, invoices, bank statements, mortgage interest statements, and anything else you used to calculate deductions or report income.
- After three years, you can shred paper documents or delete digital files, but many people keep returns longer for mortgage, loan, or insurance purposes.
- State tax returns may have different retention rules; check your state's tax authority website for the specific period.
What documents count as supporting records
Supporting documents are the papers and files you used to fill out your return. They include receipts for deductions you claimed, bank statements showing deposits and withdrawals, mortgage interest statements (Form 1098), charitable donation receipts, medical expense records, property tax bills, and anything else that proves the numbers on your return are correct.
If you claimed a home office deduction, keep the lease or deed, utility bills, and records of any improvements. If you reported self-employment income, keep invoices, payment records, and expense receipts. If you claimed education credits, keep tuition bills and proof of enrollment. If you took a loss on an investment, keep the purchase and sale confirmations.
Digital records count just as much as paper ones. Email confirmations, bank statements downloaded as PDFs, and screenshots of online transactions are all valid. The IRS does not care whether you kept the original receipt or a digital copy, as long as the document shows what you spent and when.
When to keep records longer than three years
You may need to keep tax documents longer than three years for reasons unrelated to the IRS. If you are explore for a mortgage, a lender will often ask for two years of tax returns to verify your income. If you are refinancing a home, the lender may ask for the same. Insurance companies sometimes request returns when you file a claim. Employers occasionally ask for returns during a background check.
If you own a rental property or a business, keep records for as long as you own the asset. The IRS uses these records to calculate your basis — the original cost — when you eventually sell. Without them, you may overpay capital gains tax. Similarly, if you contributed to a traditional IRA, keep records of non-deductible contributions for the rest of your life, because the IRS uses them to calculate how much of your withdrawal is taxable.
Many people keep all returns indefinitely. Storage is cheap, and there is no downside to keeping them longer than required. If you prefer to discard them, three years is the safe minimum for federal purposes.
State tax return retention rules vary
Most states follow the federal three-year rule, but some have different windows. A few states allow audits for four or five years. Some states have no statute of limitations if you did not file or underreported income significantly. Because rules differ by state, check your state's tax authority website for the specific period that applies to you.
If you file in multiple states — for example, if you worked in one state and lived in another — keep records long enough to cover the longest window among all the states where you filed. This is usually simpler than tracking different retention dates for each state.
How to organize and store tax documents
The simplest method is to create a folder for each tax year. Label it with the year and the date you filed. Put your filed return, all supporting documents, and proof of payment in the same folder. If you file electronically, print a copy of the confirmation or save the email confirmation in the folder.
For paper documents, store them in a cool, dry place away from direct sunlight. A filing cabinet, a plastic storage box, or a shelf in a closet all work. Do not store them in a basement or attic where moisture or temperature swings can damage them. If you scan documents to create digital copies, store the digital files in a cloud service like Google Drive or Dropbox so you do not lose them if your computer fails.
If you use tax software like TurboTax or H&R Block, the software usually stores a copy of your return in your account. You can log in and read it years later. This is a backup, not a replacement for your own copies — software companies can delete old accounts or change their policies.
What to do when the retention period ends
Once three years have passed, you can shred paper documents or delete digital files. A shredder is the safest method for paper because it prevents identity theft. If you do not have a shredder, you can burn documents in a fireplace or take them to a document destruction service. Do not straightforward throw them in the trash — tax returns contain your Social Security number and financial details.
For digital files, deleting them from your computer is usually enough. If you want to be thorough, use a file-shredding tool like Eraser or CCleaner, which overwrites the file so it cannot be recovered. For files stored in the cloud, delete them from your account and empty the trash or recycle bin.
Before you discard anything, double-check that you do not need it for another reason. If you are in the middle of a mortgage process or a loan underwriting process, wait until that is complete. If you own a business or rental property, keep records related to those assets longer.
Special situations that affect how long to keep records
If the IRS contacts you about an audit, stop discarding documents when ready. Keep everything related to that return indefinitely until the audit is closed and you receive a final information letter. The same applies if you are involved in a lawsuit or insurance claim that relates to your taxes — keep all relevant documents until the matter is resolved.
If you claimed a loss that you carried forward to future years — for example, a business loss or a capital loss — keep the original return and supporting documents for as long as you are using that loss. Once the loss is fully used up, you can discard the documents after three years from the year you used the last portion of it.
If you received income from a source that issued you a Form 1099 (such as freelance work or investment income), the IRS has a copy of that form. The three-year window still applies, but the IRS knows about the income, so the stakes are higher if you cannot back up the deductions you claimed against it.
Frequently Asked Questions
Do I need to keep the original receipts or are digital copies okay?
Digital copies are acceptable to the IRS. A photograph, a PDF, or a scanned image of a receipt is valid proof as long as it shows the date, the amount, and what was purchased. You do not need to keep the paper original once you have a digital copy, though many people keep both for safety.
What if I filed my taxes late — does the three-year clock still start from when I filed?
Yes. The three-year retention period starts from the date you actually filed your return, not from the original tax important date. If you filed your 2022 return in 2024, the three-year window closes in 2027, not 2025.
Can I throw away my tax return after I get my refund?
No. Keep your return and supporting documents for at least three years even after you receive your refund. The IRS can still audit you during that window, and you will need the documents to prove your deductions and income are correct.
How long should I keep records if I own a business or rental property?
Keep records for as long as you own the asset, plus three years after you sell it. The IRS uses these records to calculate your cost basis and the capital gain or loss when you sell. Without them, you may overpay taxes on the sale.
What if I lost some of my supporting documents — can I still claim the deductions?
If you cannot find a receipt, you may still be able to claim the deduction if you have other proof, such as a bank statement or a credit card statement showing the transaction. If the IRS audits you, explain what happened and provide whatever documentation you do have. The IRS will decide whether it is enough.
