Keep tax returns and supporting documents 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 it, so you need to hold onto your tax return, receipts, bank statements, and other proof of income or deductions for that full period. 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, keep records until October 15 three years later.

Three years is the standard rule, but the timeline gets longer in specific situations. If you underreported income by more than 25 percent, the IRS has six years to audit you. If you did not file a return at all, there is no time limit — the IRS can go back as far as it wants. If you filed a fraudulent return, the same applies. For most people filing honestly and completely, three years is sufficient.

Key Takeaways

  • Keep your filed tax return and all supporting documents (W-2s, 1099s, receipts, bank statements, cancelled checks) for three years from the filing date.
  • If you significantly underreported income, the IRS can audit you within six years, so keep records for six years in that case.
  • If you did not file a return or filed a fraudulent one, keep records indefinitely because there is no statute of limitations.
  • Store originals in a safe place — a fireproof box, safe deposit box, or digital scan — because the IRS will ask to see them if you are audited.
  • After the retention period ends, you can shred paper documents or delete digital files, but many people keep returns longer for mortgage, loan, or insurance purposes.

What counts as a tax return and supporting documents

Your tax return is the actual form you filed — your Form 1040 and any schedules attached to it (Schedule C for self-employment income, Schedule A for itemized deductions, and so on). Keep the copy you received from the IRS after filing, or your copy if you filed electronically and printed it yourself.

Supporting documents are the receipts, statements, and records that back up what you claimed on that return. For W-2 income, keep your W-2 forms. For 1099 income (freelance work, rental income, investment income), keep the 1099 forms and bank statements showing the deposits. For deductions, keep receipts for charitable donations, medical expenses, business expenses, mortgage interest statements, property tax bills, and anything else you deducted. If you claimed home office expenses, keep records of your home office setup and utilities. If you claimed business mileage, keep a mileage log or contemporaneous notes.

The IRS does not require you to send these documents with your return, but if you are audited, you will need to produce them. Digital copies (scanned documents, email confirmations, online bank statements) count as supporting evidence, so you do not have to keep paper originals if you have a clear digital record.

When to keep records for longer than three years

If you underreported your income by more than 25 percent, keep records for six years. The IRS defines this as gross income that is more than 25 percent lower than what it should have been. For example, if your actual income was $100,000 but you reported $70,000, that is a 30 percent underreport and triggers the six-year window. This is not about making a small math error — it is about a substantial gap between what you earned and what you reported.

If you did not file a tax return when you were required to, keep records indefinitely. The statute of limitations does not start until you file, so the IRS can audit you at any point. The same applies if you filed a fraudulent return — there is no time limit for the IRS to pursue it.

If you are self-employed or own a business, some records should be kept longer than three years for business continuity and accounting purposes, even if the IRS does not require it. Payroll records, for example, should be kept for at least four years under federal employment law.

How to store tax records safely

Paper documents degrade over time, and house fires or water damage can destroy them. Store originals in a fireproof box or safe in your home, or in a safe deposit box at a bank. If you choose a safe deposit box, be aware that the bank may seal it after your death, which can complicate things for your heirs — keep a copy of the key location and access instructions with your will or in a place a trusted person knows about.

Digital storage is increasingly practical. Scan important documents (your filed return, W-2s, 1099s, major receipts) using a smartphone app or a home scanner, and save them to a cloud service like Google Drive, Dropbox, or OneDrive. Make sure your cloud account has a strong password and two-factor authentication. Keep one backup copy on an external hard drive stored separately from your computer. If you file electronically, your tax software usually stores a copy of your return in your account — log in once a year to confirm it is still there and accessible.

Label your files clearly by year and type (for example, "2023 Tax Return," "2023 W-2s," "2023 Charitable Donations"). If you are audited, you will need to find these documents quickly, and clear labeling saves time and frustration.

What to do after the retention period ends

Once three years have passed (or six years, or longer, depending on your situation), you can shred paper documents or delete digital files. Use a shredder rather than tearing by hand — the IRS recommends cross-cut shredding to prevent reconstruction. If you have a large volume of old documents, some shredding services will do it for you and provide a certificate of destruction.

Many people keep tax returns longer than required anyway. Mortgage lenders, insurance companies, and loan officers sometimes ask to see prior-year returns, so keeping the last five to seven years is practical even after the IRS retention period ends. If you are explore for a mortgage, a car loan, or a rental lease, having recent returns on hand speeds up the process.

Do not throw away records if you are currently under audit or if the IRS has contacted you about a specific year. Wait until the audit is fully resolved and any appeals period has ended before destroying anything related to that tax year.

Common mistakes people make with tax record storage

The most common mistake is keeping records in a place where they can be lost or damaged — a basement prone to flooding, a garage where temperature swings can warp paper, or a cardboard box in the attic. Moisture and heat break down paper and fade ink, making documents illegible if you need them later. Use a climate-controlled storage space.

Another mistake is keeping only a digital copy without a backup. If your computer crashes or your cloud account is hacked, a single copy is gone. Keep at least two copies — one in the cloud and one on an external drive, or two different cloud services. Test your backups once a year by trying to open a file from each one.

A third mistake is discarding records too early. Some people throw away documents after one year, thinking the IRS will not look back that far. Three years is the standard, and it is worth the small amount of storage space to keep them that long. The cost of replacing lost documents if you are audited far exceeds the cost of storing them.

Frequently Asked Questions

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

Digital copies are acceptable to the IRS as long as they are clear and complete. You do not need to keep paper originals if you have scanned them or have a digital record (like an email receipt or online bank statement). However, if the IRS audits you and asks for proof, you need to be able to produce the document in a readable format. Keep at least one backup copy in case your primary digital file is lost.

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

You can request a transcript from the IRS, which shows the key information from your filed return. Visit IRS.gov or call 1-800-829-1040 to request a free transcript. A transcript is not the same as your original return, but it shows the IRS what you reported. If you are audited, bring the transcript plus your supporting documents (receipts, W-2s, 1099s) to show your work.

How long should I keep records if I am self-employed?

Follow the same three-year rule for the IRS, but keep business records longer for your own accounting and tax planning purposes. Many accountants recommend keeping seven years of business records. If you have employees, keep payroll records for at least four years under federal law. Consult your accountant about what makes sense for your specific business.

Can I throw away tax records after I file electronically?

No. Filing electronically does not change the retention requirement. You still need to keep your supporting documents (receipts, W-2s, 1099s, bank statements) for three years. The IRS can still audit an electronically filed return, and you will need to show proof of your income and deductions if they do.

What if I am being audited — how long do I have to keep records?

Keep all records related to the audited year until the audit is completely finished and any appeals period has ended. The IRS will tell you the important date for providing documents when they contact you about the audit. Do not discard anything until the case is closed and you have received written confirmation from the IRS.
