Keep tax returns and supporting documents for at least three years from the date you filed

The IRS can audit your return up to three years after you file it. That means you need to hold onto your actual tax return, plus every receipt, bank statement, and document you used to fill it out. If you filed on April 15, keep everything until at least April 15 three years later. If you filed an extension and submitted on October 15, count three years from October 15.

The three-year rule is the baseline for most people. It applies to W-2s, 1099s, charitable donation receipts, medical expense records, mortgage interest statements, business expense logs, and anything else that supports a number on your return. The IRS rarely audits returns older than three years, but when it does happen, it is because they found a reason to look deeper — usually underreported income or a large deduction that caught their attention.

Key Takeaways

  • Keep tax returns and all supporting documents for at least three years from your filing date, since that is how far back the IRS can audit.
  • If you underreported income by 25 percent or more, the IRS can audit up to six years, so keep records that long if you know you made a significant error.
  • If you never filed a return for a year, there is no time limit — the IRS can go back as far as they want.
  • You can discard documents after the retention period ends, but keep your actual filed return itself indefinitely for your own records.
  • Digital copies, scans, and photos of receipts count as valid records, so you do not have to store paper originals if you have clear images.

When to keep records for six years instead of three

The IRS extends the audit window to six years if you underreported your income by 25 percent or more. This is not about making an honest mistake on a deduction — it is about income you did not report at all. If your actual income was $100,000 and you reported $75,000, that is a 25 percent underreport, and the six-year rule kicks in.

You may not know whether you hit that threshold until you discover the error yourself. If you find it, you can file an amended return (Form 1040-X) and the six-year clock usually does not start until the IRS receives that amendment. If the IRS finds it first during an audit, they will assess penalties and interest going back six years. The safest approach: if you suspect you underreported income significantly, keep all supporting documents for six years.

No time limit if you never filed

If you did not file a tax return for a particular year and the IRS knows you should have, there is no statute of limitations. They can audit that year at any point. This applies even if you filed late — say you filed 2019 taxes in 2021. Once you file, the three-year clock starts. But if you never filed at all, the IRS can come after you indefinitely.

This is one reason to file even if you owe money or expect a small refund. Filing stops the clock. If you are unsure whether you filed a particular year, you can request a transcript from the IRS showing which years they have on record — that costs nothing and takes about two weeks.

What documents to actually keep

Your tax return itself is the main document. Keep the actual Form 1040 (or 1040-SR if you are over 65), plus any schedules you filed with it — Schedule A if you itemized deductions, Schedule C if you are self-employed, Schedule D if you sold investments. These are the pages you signed and submitted.

Then keep everything that backs up the numbers on those pages. For W-2 income, keep the W-2 itself. For self-employment income, keep invoices, receipts, bank statements showing deposits, and mileage logs if you claimed vehicle expenses. For deductions, keep receipts for charitable donations, medical bills, property tax statements, and mortgage interest statements (your lender sends Form 1098). For investment income, keep brokerage statements and records of what you paid for each stock or fund you sold.

You do not have to keep every grocery receipt or gas station receipt unless you are claiming business expenses. The IRS focuses on large or unusual items. A $50 office supply purchase probably does not need documentation if you are self-employed, but a $5,000 equipment purchase does.

Digital records and scans are acceptable

You do not have to keep paper. The IRS accepts digital copies, scans, and photographs of receipts and documents. Take a photo of a receipt with your phone, store it in a folder on your computer or cloud drive, and that counts as your record. The image has to be clear enough to read — if the date, amount, and vendor are legible, you are fine.

Many people scan documents as they receive them and throw away the paper. That is a valid system. Some use apps that automatically photograph and organize receipts. Others keep a folder for each tax year on Google Drive or Dropbox. The method does not matter as long as you can produce the document if the IRS asks. If you cannot read the image, it does not count.

What happens after three years

Once three years have passed (or six years if you underreported income), you can throw away supporting documents. Shred them if they contain Social Security numbers, account numbers, or other sensitive information. You do not have to keep the receipts, bank statements, or invoices anymore.

Keep your actual filed tax return itself indefinitely, even after the retention period ends. It costs nothing to store a PDF or a paper copy, and you may need it for other reasons — applying for a mortgage, proving income to a landlord, or checking your own financial history. The return itself is not bulky. The supporting documents are what take up space.

Special situations that change the timeline

If you claimed a loss and carried it forward to a future year, keep records for that loss until three years after the year you used it up. If you claimed a bad debt deduction, keep the documentation showing you tried to collect. If you deducted a home office, keep records of your home expenses for three years after you stop claiming the deduction.

If you received a notice from the IRS about a specific year, do not throw away those records until the audit is closed and the time to appeal has passed. The IRS will tell you in writing when the examination is complete. After that, the three-year rule applies again — count three years from the date the audit closed.

Frequently Asked Questions

Do I have to keep receipts if I use tax software or a preparer?

Yes. Your tax preparer or software company does not keep your documents for you. They use them to fill out your return, then you are responsible for storing them. If the IRS audits you, they will ask you for the receipts and documents, not your preparer. Keep everything yourself.

What if I lost my receipts but I have bank statements showing the transactions?

Bank statements can work as backup documentation for many expenses. If you donated $500 to charity and your bank statement shows a transfer to that charity, that is evidence. For business expenses, a credit card statement or bank record showing a purchase from a vendor is often enough. The IRS prefers itemized receipts, but statements can substitute if the receipt is gone.

Can I throw away my return after I file electronically?

No. Keep a copy of your filed return even though you submitted it electronically. Print the confirmation page the IRS sends you, or save the PDF your tax software generated. You need proof of what you reported, and the IRS does not automatically send you a copy. Your own records are your proof.

How do I know if the IRS is going to audit me?

The IRS mails you a notice if they select your return for examination. They do not call or email first. If you receive a letter, it will specify which items they want to review and what documents to bring or mail. You do not find out you are being audited any other way. If you have not received a letter, you are not under audit.

Should I keep records for more than six years just to be safe?

You can, but it is not necessary. After six years, the IRS cannot go back further unless you never filed or committed fraud. Keeping records longer takes up space and serves no tax purpose. Three years is the standard; six years covers the underreporting scenario. Beyond that, you are storing documents the IRS cannot legally use.
