Keep your tax returns and documents for at least three years after you file

The IRS expects you to keep your filed tax return and the documents that support it for a minimum of three years from the date you file or the date the return was due, whichever is later. This three-year window is the standard lookback period the IRS uses to audit returns. If you file on April 15 and the IRS decides to examine your 2023 return in 2026, you will need to produce those documents. After three years passes, you can discard them—but only if certain conditions are met.

The three-year rule is not absolute. If you underreported income by 25 percent or more, the IRS can go back six years. If you filed a fraudulent return or did not file at all, there is no time limit. 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, and longer if you are self-employed, own rental property, or had any unusual transactions that year.

Key Takeaways

  • The IRS can examine your return for three years after you file, so keep your tax return and all supporting documents for at least that long.
  • If you underreported income by 25 percent or more, the IRS has six years to audit you, so extend your retention period accordingly.
  • Self-employed people and those with rental income should keep records for at least six years because business and rental deductions are audited more frequently.
  • You can store documents digitally by scanning them, but keep the originals for at least one year in case the IRS asks to see them.
  • After the retention period ends, shred documents containing personal information like Social Security numbers and bank account details.

What documents to keep with your tax return

Your tax return itself is only part of the story. The IRS wants to see the documents that prove every number on that return. If you claimed a mortgage interest deduction, keep the Form 1098 from your lender. If you reported investment income, keep the 1099-INT or 1099-DIV. If you deducted charitable donations, keep the receipts or written acknowledgment from the charity. If you paid medical expenses, keep the bills and insurance statements.

For employment income, keep your W-2 forms and any pay stubs that show withholding. For self-employment income, keep invoices, receipts, mileage logs, and bank statements that document what you earned and what you spent. For rental property, keep the lease, mortgage statements, repair receipts, property tax bills, and insurance documents. For investment losses, keep the brokerage statements showing the purchase price and sale price. The rule is straightforward: if a number appears on your return, you should have a document that explains where it came from.

How long to keep records if you are self-employed

Self-employed people face a higher audit rate than W-2 employees, so the IRS recommends keeping business records for at least six years. This includes income records (invoices, receipts, bank statements), expense records (receipts for supplies, equipment, rent, utilities), and mileage logs if you claim vehicle deductions. The six-year window gives you a buffer because business deductions are more likely to be questioned than standard deductions.

If you claim a home office deduction, keep the documents that prove your home office exists and the square footage you use for business. If you depreciate equipment or vehicles, keep the purchase receipts and the depreciation schedule you filed with your return. If you have employees, keep payroll records, W-2 copies, and 1099 forms for at least four years. The longer you keep these records, the easier it is to respond if the IRS contacts you.

Retention rules for rental property and investment income

Rental property owners should keep records for at least six years because rental deductions are frequently audited. This includes the lease, property tax bills, mortgage statements, insurance documents, repair and maintenance receipts, utility bills, and any records of improvements you made to the property. If you depreciated the building, keep the original purchase documents and the depreciation schedule. If you sold the property, keep all records related to the sale for at least six years after the sale closes.

For investment income and losses, keep brokerage statements, trade confirmations, and cost basis documentation for at least six years. If you sold a stock at a loss and want to claim a wash-sale deduction, the IRS will want to see the purchase and sale dates and prices. If you inherited securities, keep the valuation statement from the date of death. If you received a K-1 from a partnership or S corporation, keep it and the supporting documents for at least six years.

Digital storage and document organization

You can store tax documents digitally by scanning them to PDF or taking photographs with your phone. The IRS accepts digital copies as long as they are clear, complete, and show all the information on the original. Many people scan documents and store them in a folder on their computer, in cloud storage like Google Drive or Dropbox, or in a dedicated tax software folder. Label each file with the year and document type so you can find it quickly if you need it.

Keep at least one physical copy of your filed tax return in a safe place, such as a filing cabinet or safe deposit box. If the IRS asks to see your documents, you may need to produce originals, especially for large deductions or unusual transactions. After you have kept the documents for the required period and you are certain the IRS will not examine that return, you can discard them. Shred documents that contain sensitive information like your Social Security number, bank account numbers, or credit card numbers before throwing them away.

When the IRS can go back more than three years

The three-year rule has exceptions. If you underreported your income by 25 percent or more, the IRS has six years to audit you. This means if your return showed $40,000 in income but you actually earned $50,000 or more, the six-year clock starts. If you filed a fraudulent return or did not file at all, there is no statute of limitations—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.

If you received income from a foreign source or have foreign financial accounts, keep those records for at least six years. If you claimed a net operating loss carryback or carryforward, keep the records for the year you claimed the loss and the year you carried it forward. The safest approach is to ask yourself: "Could the IRS question this number?" If the answer is yes, keep the supporting document for at least six years.

What to do when the retention period ends

Once three years (or six years, or seven years, depending on your situation) have passed since you filed, you can discard the documents. Before you throw them away, make sure the statute of limitations has truly expired. The three-year clock starts from the date you filed your return, not the date the return was due. If you filed your 2023 return on March 1, 2024, the three-year period ends on March 1, 2027. If you filed it on October 15, 2024, the period ends on October 15, 2027.

Shred documents that contain personal information. Do not straightforward throw them in the trash where someone could retrieve them. A cross-cut shredder is inexpensive and effective. Some banks and credit unions offer free shredding events. Once you have shredded the documents, you can discard them. Keep your filed tax return itself for longer if you want—many people keep returns indefinitely because they take up little space and may be useful for reference later.

Frequently Asked Questions

Do I need to keep the original documents or just copies?

Digital copies are acceptable for most situations, but keep at least one original of your filed return. If the IRS asks to examine your return, they may request originals of large deductions or unusual items. Scanning documents and storing them digitally is a practical solution, but do not discard the originals until you are certain the retention period has ended.

What if I file an amended return—does the three-year clock restart?

If you file an amended return (Form 1040-X), the three-year period runs from the date you filed the amended return, not the original return. Keep all documents related to both the original and amended returns for at least three years from the amended filing date. If the amendment involved a significant change in income or deductions, consider keeping records for six years.

Can I throw away documents after the IRS sends me a closing letter?

A closing letter means the IRS has finished examining that specific return, but it does not mean you must discard documents when ready. Keep them for the full three-year period from your filing date. After that period ends, you can safely discard them. A closing letter straightforward confirms that the audit is complete.

How long should I keep records if I received a notice of deficiency?

If the IRS sent you a notice of deficiency or you are in an active dispute with the IRS, keep all documents indefinitely until the matter is resolved and any appeals are complete. Once the case is closed and the statute of limitations has expired, you can discard them. Do not throw away documents while a case is pending.

What about documents for returns I have not filed yet?

If you have not filed a return for a particular year, keep all documents related to that year indefinitely until you file. Once you file, the three-year retention period begins. If you never filed a return for a year you should have, the IRS has no time limit to examine you, so keep those records as long as possible.
