Keep tax returns and records for at least three years from the date you filed
The Internal Revenue Service (IRS) generally has three years from the date you file to audit your return. This is the baseline: keep everything for three years. That means your actual tax return form, all receipts, bank statements, cancelled checks, invoices, and anything else you used to fill it out.
Three years is not a hard important date where you can shred documents on day 1,096. The IRS can go back further if they suspect underreported income or fraud. If you underreported income by 25 percent or more, they have six years. If they suspect criminal activity, there is no time limit at all. Keeping records longer than three years costs you nothing but storage space, and it protects you if questions come up later.
Key Takeaways
- The IRS has three years to audit most returns, so keep your return and all supporting documents for at least that long.
- If you underreported income by a significant amount, the IRS can go back six years, so longer storage is safer.
- Keep records even after you file: receipts, bank statements, invoices, and proof of deductions all matter if your return is questioned.
- Some documents like mortgage statements and investment records should be kept longer because they affect future tax years or capital gains calculations.
What documents to keep with your tax return
Your tax return itself is only one piece. The IRS does not just want to see the number you reported—they want to see how you got there. Keep the actual forms you filed (1040, schedules, any amendments) plus every document that supports the numbers on those forms.
For income, that means W-2s from employers, 1099s from clients or investment accounts, bank statements showing deposits, and proof of any other money you received. For deductions, keep receipts, invoices, cancelled checks, credit card statements, and mileage logs. If you claimed a home office deduction, keep the square footage calculation and utility bills. If you deducted medical expenses, keep the bills and proof of payment. If you donated to charity, keep the receipts or written acknowledgment from the organization.
The rule is straightforward: if a number appears on your return, you should be able to show where it came from. Digital copies are fine—the IRS accepts scans and photos of receipts. Many people photograph receipts as they go, then store them in a folder on their phone or computer.
How long to keep records for specific situations
Three years covers most people most of the time. But certain situations call for longer storage. If you own a home, keep the purchase documents, mortgage statements, and records of improvements (new roof, kitchen remodel, foundation work) indefinitely or at least until you sell. These affect your cost basis and capital gains tax when you eventually sell the house.
If you own investments or a business, keep records for at least seven years. Business owners should keep payroll records, expense receipts, and profit-and-loss statements for seven years because employment tax records have a longer statute of limitations. If you contributed to a retirement account, keep the contribution records and any statements showing the account balance, because you will need them to calculate your basis when you withdraw money in retirement.
If you received a large gift or inheritance, keep the documentation. If you sold property at a loss, keep those records longer because you may carry the loss forward to future years. The safest approach: if you are unsure, keep it for seven years. Seven years covers nearly every scenario the IRS might revisit.
Where to store tax documents safely
Physical documents can be lost to fire, flood, or straightforward disorganization. A fireproof box or safe is better than a filing cabinet. Many people scan important documents and store the digital copies in cloud storage (Google Drive, Dropbox, OneDrive) so they have a backup if the originals are damaged.
If you use tax software or work with a tax preparer, ask whether they keep copies. Many do, for at least three to seven years. That does not mean you should not keep your own copies—it is a backup, not a replacement. Label your storage clearly by year so you can find what you need quickly if the IRS contacts you.
Do not throw away documents the moment three years pass. Set a calendar reminder for year four or five to review what you can safely discard. Shred documents with sensitive information (Social Security numbers, bank account details, tax ID numbers) rather than just tossing them in the trash.
What happens if the IRS asks about an old return
If the IRS contacts you about a return from two or three years ago, you will need to show your work. This is called an audit, and it can be as straightforward as mailing in receipts or as involved as an in-person meeting. The IRS will tell you which items they want to review. You then have the burden of proving what you reported was correct.
If you cannot find the documents, you can still respond—the IRS will not automatically assume you are lying. But you will have a harder time proving your case. You might be able to reconstruct records (ask your bank for statements, contact vendors for copies of invoices), but it takes time and effort. Keeping documents from the start is far easier than reconstructing them years later.
If you filed an amended return (Form 1040-X), keep that and all supporting documents for three years from the date you filed the amendment, not the original return. The clock restarts.
When you can safely discard old returns
After seven years, you can discard most tax documents without worry. The only exceptions are records tied to ongoing situations: if you still own the house you bought in 2010, keep the purchase documents. If you still own the investment account, keep the statements. If you are still receiving income from a source you reported in 2015, keep those records.
Before you discard anything, ask yourself: does this document affect a future tax year? If the answer is yes, keep it. If it is purely historical—a receipt for a deduction you claimed in 2020 and will never claim again—you can discard it after seven years.
Some people keep everything forever. That is not necessary, but it is not wrong either. The cost of storage is low. The cost of not having a document when you need it is high. If you are uncertain, err on the side of keeping it.
Frequently Asked Questions
Do I need to keep the actual paper return, or is a digital copy enough?
A digital copy is fine. Scan or photograph your filed return and all supporting documents. The IRS accepts digital records as evidence. Keep the digital files in at least two places—your computer and cloud storage, for example—so you do not lose them if one device fails.
What if I filed my return electronically and never printed it?
You should have received a confirmation email or number when you filed. Keep that. You can also log into the IRS website or your tax software account and read a copy of what you filed. Print it or save it as a PDF and store it with your supporting documents.
Can I throw away receipts after I file my return?
Not when ready. Keep receipts for at least three years. The IRS does not typically ask for original receipts—a copy or photograph is acceptable—but you need something to show where the numbers on your return came from. Discarding them right after filing leaves you vulnerable if questions come up later.
How long should I keep records if I am self-employed?
Keep business records for at least seven years. Self-employed people face longer audit windows because employment tax records have a six-year statute of limitations. Keep invoices, receipts, bank statements, mileage logs, and profit-and-loss statements for the full seven years.
What if I made a mistake on an old return—how far back can I fix it?
You can file an amended return (Form 1040-X) going back three years from the original filing date. If you owed money and did not pay, the IRS can pursue you longer. If you are owed a refund, file the amendment as soon as you realize the error—refunds expire after three years.
