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

The Internal Revenue Service (IRS) can audit your return up to three years after you file, which is why three years is the standard minimum. If you filed on April 15, keep that year's documents through April 15 three years later. If you filed an extension and submitted on October 15, count from that date instead.

However, three years is not a hard rule in every situation. The IRS can go back six years if it suspects you underreported income by 25 percent or more. If you never filed a return for a particular year, there is no time limit — the IRS can pursue that indefinitely. If you filed a fraudulent return, the same applies.

For most people filing honestly and on time, three years covers the risk. But certain documents — especially those tied to property, investments, or major deductions — should stay longer.

Key Takeaways

  • Keep your filed tax return and all supporting documents (W-2s, 1099s, receipts, bank statements) for at least three years from the filing date.
  • The IRS can audit back six years if it suspects significant underreported income, so keeping records longer provides extra protection.
  • Documents related to home purchases, stock sales, or retirement accounts should be kept for seven years or longer, depending on the asset.
  • Once you are certain the IRS will not audit (after three to six years), you can safely discard paper returns, but keep digital copies of key documents indefinitely.

What documents to keep with your tax return

Do not just keep the return itself. Store everything you used to prepare it: W-2 forms from your employer, 1099 forms for freelance income or interest, receipts for deductible expenses, charitable donation records, medical bills if you itemized, mortgage interest statements, property tax bills, and bank or brokerage statements showing income or losses.

If you took the standard deduction, you technically do not need receipts — but if the IRS asks about your income, you will need proof of what you earned. If you itemized deductions, receipts become critical. Keep them organized by category (medical, charitable, business, etc.) so you can find them quickly if audited.

Digital copies count. A photograph of a receipt, a PDF read from your bank, or a scanned document is acceptable to the IRS. Many people now photograph receipts as they spend and store them in a folder on their phone or computer, then delete the paper. That works, as long as the image is legible.

How long to keep records tied to assets and investments

If you own a home, keep the purchase documents, closing statement, and receipts for major improvements (new roof, addition, foundation work) for as long as you own the house, plus three years after you sell it. The IRS uses these to calculate your cost basis — the amount you paid plus improvements — which determines your taxable gain when you sell.

For stocks, mutual funds, or other investments, keep the purchase confirmation and sale confirmation for at least three years after you sell, but many tax professionals recommend seven years. If you reinvested dividends, keep those statements too, because they affect your cost basis.

For retirement accounts like IRAs or 401(k)s, keep the annual statements and any contribution records for the life of the account, plus three years after you close it. The IRS tracks whether you have taken required minimum distributions, and your records prove you did.

When you can safely throw documents away

After three years have passed with no audit notice, you can discard paper copies of your return and most supporting documents. However, keep digital versions of anything related to ongoing assets: home purchase papers, investment records, and retirement account statements. These take almost no space in cloud storage and protect you if a question arises years later.

For documents tied to assets you no longer own — a house you sold five years ago, a stock you liquidated — you can delete them once three years have passed since the sale. The IRS is not going to audit a transaction from a decade ago unless there was fraud.

One exception: if the IRS has contacted you about an audit or sent a notice, do not throw anything away until the audit is closed and the time to appeal has passed. Keep those documents until the IRS confirms the matter is settled.

Organizing documents so you can find them during an audit

The easiest system is a folder for each tax year. Inside, create subfolders: Income (W-2s, 1099s), Deductions (receipts by type), and Assets (home, investments). Label everything with dates. If you use tax software, many programs let you attach documents directly to line items, which creates a searchable record.

For paper documents, a filing cabinet or accordion file works. Write the tax year on the outside. For digital documents, use your computer's file system or a cloud service like Google Drive or Dropbox. Name files clearly: "2023_Home_Improvement_Receipts" is better than "Receipts_2023" because it tells you what is inside without opening it.

If you work with a tax preparer or accountant, ask whether they keep copies. Many do for three to seven years, which means you have a backup. But do not rely on that — keep your own copies in case you change preparers or they go out of business.

Special situations that change the timeline

If you claimed a loss carryforward — a business loss or investment loss you are spreading across multiple years — keep those documents for the entire period you are using the loss, plus three years after. The IRS needs to see how you calculated the loss and how you are explore it each year.

If you received a notice of deficiency or the IRS sent you a letter about a specific issue, keep everything related to that matter until the case is fully resolved and any appeal period has ended. This can extend the timeline well beyond three years.

If you are self-employed, the IRS can audit back six years as a standard practice (not just when fraud is suspected), so keep business records for six years. This includes invoices, expense receipts, mileage logs, and bank statements.

Digital storage and backup considerations

Storing documents digitally is safer than paper in many ways — no fire, flood, or accidental disposal — but only if you back them up. A single hard drive can fail. Use cloud storage (Google Drive, OneDrive, iCloud) or keep copies in two places: your computer and an external drive, or two different cloud services.

Make sure your digital files are organized clearly enough that someone else could find them if needed. If you become unable to manage your taxes, a family member or accountant should be able to locate your records without a hunt.

Consider password-protecting sensitive files or using encrypted storage if your documents contain Social Security numbers or bank account details. The IRS does not require this, but it protects your information from theft or misuse.

Frequently Asked Questions

What if I lost my tax return but still have the receipts?

You can request a transcript from the IRS showing what you filed. Call 1-800-829-1040 or visit irs.gov and search "Get Your Tax Record." A transcript shows your filing status, income, and tax paid, which is usually enough if audited. Keep the receipts — they prove the details behind the numbers on the transcript.

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

You do not need them to file, but keep them anyway for three years. If audited, the IRS may ask about your income sources or ask you to prove you did not have deductible expenses you should have claimed. Receipts protect you either way.

Can I throw away documents after the statute of limitations expires?

Yes, after three years (or six for self-employed) with no audit notice, you can discard paper documents. But keep digital copies of anything tied to ongoing assets like a home or investment account, since these may be relevant to future tax years or sales.

What if I filed an amended return?

Keep the amended return and all supporting documents for three years from the date you filed the amendment, not the original return. If you amended multiple times, keep records for three years from the most recent amendment.

Should I keep credit card statements and bank statements?

Keep them for the year you filed plus three years. They prove income deposits and deductible expenses. After that, you can discard them unless they relate to an ongoing asset or investment.
