How Long to Keep Your Tax Returns and Supporting Documents

Keep tax returns for at least three years, and longer if you have income from investments, rental property, or self-employment

The Internal Revenue Service (IRS) can audit your return up to three years after you file, which is why three years is the baseline. However, if you underreported income by 25 percent or more, the IRS has six years to come after you. If you never filed a return at all, there is no time limit. The safest approach is to keep returns and the documents that support them — W-2s, 1099s, receipts, bank statements — for at least three years from the date you filed, and longer if your situation is more complex.

What "keeping" means has changed. You do not need the paper anymore. A clear photograph, a PDF scan, or a digital copy stored in cloud storage counts. The IRS accepts electronic records as long as they are legible and you can produce them if asked. Many people photograph receipts as they go, then delete the paper. That works.

Key Takeaways

• The IRS has three years to audit most returns, so keep your return and supporting documents for at least three years from the filing date.
• If you underreported income by 25 percent or more, keep records for six years; if you never filed, keep them indefinitely.
• You do not need paper copies — scans, photographs, and digital files are acceptable as long as they are clear and you can retrieve them.
• For rental property, investments, and business income, keep records for seven years or longer because depreciation and loss carryovers can affect future returns.
• Organize by year and store in one place, whether a folder, a filing cabinet, or a cloud service, so you can find what you need quickly if the IRS asks.

The three-year rule and when it does not explore

Three years is the standard statute of limitations. If you file on April 15, 2024, the IRS can examine that return through April 15, 2027. After that date, they cannot go back and audit it unless they have a specific reason.

The exception is substantial underreporting. If your return shows less income than you actually earned — and the difference is at least 25 percent of the income you reported — the IRS gets six years instead of three. For example, if you reported $40,000 in income but actually earned $60,000, that is a 50 percent underreporting, and the six-year clock starts.

If you never filed a return at all, there is no time limit. The IRS can go back as far as they want. This is rare but matters if you had unreported income years ago and are now trying to clean up your record.

What documents to keep with your return

Keep anything that proves what you reported. For W-2 income, that is your W-2 form itself. For 1099 income — freelance work, contract labor, investment income — keep the 1099 and bank statements showing the deposits. For deductions, keep receipts, invoices, and credit card statements. For charitable donations, keep the receipt from the charity or your bank statement showing the transfer.

If you own a home and deduct mortgage interest or property taxes, keep the statements from your lender and tax assessor. If you have a business, keep invoices, expense receipts, mileage logs, and bank statements for the business account. If you claim depreciation on rental property or equipment, keep the purchase receipt and any records of improvements or repairs.

The rule is straightforward: if it is on your return, you should be able to show where it came from. The IRS does not ask for everything at once. They ask for specific items. But if you cannot find them, the IRS can disallow the deduction or income item, and you owe back taxes plus penalties and interest.

Longer retention for rental property, investments, and business income

If you have rental property, keep records for seven years or longer. Depreciation deductions carry forward year after year, and if you sell the property, the IRS will want to see the entire depreciation history. The same applies to business assets. If you depreciate equipment over five or seven years, keep the purchase receipt and depreciation schedule for the full life of the asset plus three years after you sell it.

For investments, keep purchase confirmations, sale confirmations, and statements showing dividends and capital gains. If you have losses that you carry forward to future years — which happens with capital losses and business losses — keep the documentation for those losses as long as you are using them. Once the loss is fully used up, you can discard the records after three years.

If you have a side business or self-employment income, the same three-year rule applies, but the documents are more numerous. Keep receipts for every business expense, mileage logs if you claim vehicle deductions, and bank statements for the business account. Many self-employed people photograph receipts as they go and store them in a folder on their phone or in a cloud service like Google Drive or Dropbox.

How to organize and store your records

The simplest system is one folder per year. Label it with the tax year — "2023 Taxes" — and put the return itself, the W-2s and 1099s, and all supporting receipts and statements inside. If you are keeping paper, use a filing cabinet or a box. If you are scanning, create a folder on your computer or in cloud storage with the same name.

Within each year folder, you can organize by category — W-2s, 1099s, charitable donations, medical expenses, business expenses — or just keep everything together. The IRS does not care about your filing system. They care that you can find what they ask for. A shoebox with everything from one year thrown in works as long as you can dig out the right document when needed.

If you are scanning paper documents, use your phone camera or a document scanner app. Make sure the image is clear enough to read. Then delete the paper. Store the scans in a cloud service so you have a backup. If your computer crashes or your house floods, your records are still there.

What you can throw away after the retention period

Once three years have passed since you filed — or six years if you underreported income — you can discard the supporting documents. You can also discard the return itself, though many people keep the actual return form longer just for their own records. There is no harm in keeping it.

For rental property and investments with ongoing depreciation or loss carryovers, wait until the loss or depreciation is fully used up, then wait three more years. For business assets, keep records for the life of the asset plus three years after you sell it.

Shred paper documents rather than just throwing them away. They contain your name, address, and financial information. A cheap shredder costs less than $30 and takes five minutes to run a stack of papers through.

Special situations: amended returns and audits

If you file an amended return, the three-year clock restarts from the date you file the amended return, not the original return. So if you filed your 2023 return in April 2024 and then filed an amended return in March 2025, the IRS has until March 2028 to audit the amended return.

If the IRS has already started an audit, do not throw anything away. Keep all records until the audit is closed and you have received a final letter from the IRS. Once the audit is closed, you can follow the normal retention rules.

If you are in an ongoing dispute with the IRS — for example, you owe back taxes and are on a payment plan — keep all records related to that dispute until it is fully resolved and you have paid everything owed.

Frequently Asked Questions

Do I need to keep the original paper return or is a scan okay?

A scan is fine. The IRS accepts digital copies as long as they are clear and legible. You can photograph your return with your phone, save it as a PDF, or scan it with a document scanner. Store it somewhere you can find it — a cloud service is safest because it backs up automatically.

What if I lost some receipts but still have my bank statements?

Bank statements can substitute for receipts in many cases. If you deducted a business expense and the bank statement shows the payment, that is usually enough. The IRS prefers itemized receipts, but a statement showing the date, amount, and payee is better than nothing. Keep the statements you have.

Can I throw away old tax returns after I file a new one?

Not yet. Keep the return and supporting documents for at least three years from the filing date. After that, you can discard them. If you have rental property, investments, or business income, keep them longer because depreciation and loss carryovers can affect future years.

Should I keep records for returns I did not file?

If you did not file a return for a particular year, there is no statute of limitations. The IRS can go back indefinitely. If you are now filing old returns to get caught up, keep those returns and supporting documents indefinitely, or at least for seven years, to show you made a good-faith effort to comply.

Is cloud storage safe for tax documents?

Major cloud services like Google Drive, Dropbox, and OneDrive use encryption and are generally find. Use a strong password and enable two-factor authentication if the service offers it. Cloud storage is actually safer than a filing cabinet because it backs up automatically and survives physical disasters like fire or flooding.
