How long you need to keep tax returns depends on your situation, but the general rule is three years

The Internal Revenue Service (IRS) recommends keeping your tax returns and supporting documents for at least three years from the date you filed or the due date, whichever is later. This three-year window covers most situations where the IRS might want to examine your return or ask questions about deductions, income, or credits you claimed.

However, three years is not a hard stop for everyone. If you underreported income by 25 percent or more, the IRS can look back six years. If you filed a fraudulent return or did not file at all, there is no time limit — the IRS can go back as far as it wants. If you claimed a loss from a worthless security or a bad debt deduction, keep those records for seven years.

The safest approach for most people is to keep everything for at least three years, then decide based on your specific situation whether to hold on longer.

Key Takeaways

  • Keep tax returns and receipts for at least three years from the filing date or due date, whichever is later.
  • If you underreported income by 25 percent or more, the IRS can audit you for six years instead of three.
  • Keep records related to home sales, investments, and retirement accounts for as long as you own the asset, plus three years after you sell or close it.
  • Documents supporting deductions — receipts, invoices, bank statements, mileage logs — must be kept for the same three-year period as your return.
  • Storing copies digitally or on paper both work, but make sure you can produce the originals if the IRS asks.

What counts as supporting documents you need to save

Supporting documents are the receipts, invoices, statements, and records that back up what you put on your return. If you claimed a home office deduction, keep the lease or mortgage statement and utility bills. If you deducted business mileage, keep a mileage log. If you claimed charitable donations, keep the receipts or bank statements showing the transfer.

For income, save W-2s, 1099s, K-1s, and any other forms showing what you earned. For deductions, save whatever proves you spent the money: credit card statements, bank statements, receipts, invoices, cancelled checks. For credits like the Earned Income Tax Credit or Child Tax Credit, keep documents proving your income and the number of dependents you claimed.

The IRS does not require you to send these documents with your return, but if you are audited, you will need to produce them. Having them organized and straightforward to find makes the process faster and less stressful.

When to keep records longer than three years

If you own a home, keep the purchase documents, closing statement, and records of improvements (new roof, kitchen remodel, foundation work) for as long as you own the house, plus three years after you sell it. The IRS uses these to calculate your capital gains when you sell, and you may need them to prove your cost basis.

If you have investments — stocks, bonds, mutual funds, cryptocurrency — keep the purchase confirmation, cost basis records, and sale documents for three years after you sell. If you contributed to a traditional or Roth IRA, keep the contribution records and annual statements for as long as the account exists, plus three years after you close it or withdraw everything.

If you claimed a loss from a worthless security (a stock or bond that became worthless) or a bad debt deduction, keep those records for seven years. If you have a home office, keep the records supporting that deduction for three years, but also keep the home purchase and improvement documents for the longer period mentioned above.

How to organize and store your documents

You can keep documents on paper or digitally — the IRS accepts both. Many people scan receipts and statements into a folder on their computer or cloud storage, then shred the originals after a year or two. This saves space and makes documents easier to find. If you scan, make sure the image is clear enough to read all the important information: date, amount, what was purchased, and who you paid.

A straightforward system works best: create a folder for each year, then subfolders for income, deductions, and credits. Keep your actual tax return (the PDF or printed copy) in the same folder as the documents that support it. If you use tax software, read and save your return after you file — do not rely on the software company to keep it forever.

If you use a tax professional, ask them whether they keep copies of your returns and documents. Many do, but their retention period may be shorter than yours, so it is still wise to keep your own copies.

What happens if you cannot find a document

If the IRS audits you and you cannot find a receipt or statement, you are not automatically disqualified from the deduction. You can reconstruct the expense using other evidence: credit card statements, bank statements, cancelled checks, or even a written statement explaining what you spent and why. The IRS prefers original receipts, but it will consider other proof if you can show a clear pattern of spending.

If you lost documents before the three-year window closed, tell the IRS what happened and provide whatever evidence you do have. If you lost them after three years have passed, you generally do not need to worry — the IRS is unlikely to audit that far back unless there is a specific reason to.

Special situations: business owners and self-employed people

If you are self-employed or own a business, the same three-year rule applies to your business tax return and supporting documents. However, keep payroll records (W-2s you issued, payroll tax deposits, 1099s you issued) for at least four years after the date you filed the related payroll tax return. Keep records of business assets — equipment, vehicles, furniture — for as long as you own them, plus three years after you sell or dispose of them.

If you have employees, keep their I-9 forms and hiring records for three years from the hire date or one year after the employment ends, whichever is later. Keep timesheets and wage records for at least three years. These rules exist because the IRS and the Department of Labor both have authority to audit payroll records.

Frequently Asked Questions

Can I throw away my tax return after three years?

You can, but many people keep them longer as a personal record. After three years, the IRS is unlikely to audit unless you underreported income significantly or claimed something unusual. If you own a home or have investments, keeping returns longer helps you track cost basis for future sales.

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

Photos or scans are fine for your own records. If audited, the IRS prefers originals but will accept clear digital images. Make sure the image shows the date, amount, vendor name, and what was purchased. Keep the originals for at least a year in case the IRS asks to see them.

What if I filed an amended return — how long do I keep those records?

Keep amended returns and their supporting documents for the same three-year period as your original return, measured from when you filed the amendment. If you amended a 2021 return in 2023, keep those records until 2026.

Does the IRS ever contact you about documents after three years?

Rarely. The IRS typically initiates audits within three years of filing. If they do contact you after three years, it usually means they found a significant issue like unreported income or a fraudulent deduction. If that happens, you should consult a tax professional or attorney.

Should I keep bank statements and credit card statements forever?

Keep them for three years to match your tax return period. After that, you can discard them unless they relate to a home, investment, or business asset you still own. Many banks and credit card companies keep digital copies for seven years anyway, so you can request them later if needed.
