Keep tax returns and supporting documents for at least three years

The IRS generally has three years from the date you file to audit your return and assess additional tax. This three-year window is the most common reason to keep records — it covers the statute of limitations for most situations. However, three years is a minimum, not a universal answer. The actual time you need to keep documents depends on what the documents are, whether you claimed certain deductions, and whether you sold property.

The safest approach is to keep your tax return itself (the form you filed) permanently, and keep supporting documents (receipts, statements, invoices) for at least seven years. This covers the three-year audit window, the six-year window if the IRS suspects you underreported income by 25 percent or more, and gives you a buffer for records related to property sales or business losses that may be examined years later.

Key Takeaways

  • Keep your filed tax return permanently; keep receipts and supporting documents for at least seven years to cover all common audit scenarios.
  • The IRS has three years to audit most returns, but six years if it suspects you underreported income by 25 percent or more.
  • Keep records related to home purchases, home improvements, and investment property indefinitely, because the IRS can examine these deductions years after you sell.
  • If you claimed a loss on a business or investment, keep those records for seven years even if the business is closed.
  • Keep records of estimated tax payments, extensions you filed, and any correspondence with the IRS for at least seven years.

Three years covers most audits

The three-year rule applies to the majority of tax returns. If you file your 2023 return in April 2024, the IRS can generally examine it through April 2027. This window covers wage income, standard deductions, most itemized deductions, and credits like the Earned Income Tax Credit.

Within this three-year window, you need receipts, bank statements, and other documents that prove what you reported. For example, if you claimed charitable donations, keep the donation receipts. If you claimed business expenses, keep invoices and credit card statements. If you claimed medical expenses, keep the bills and insurance statements. The IRS does not need originals — copies, digital photos, or statements from your bank or credit card company all count as proof.

Six years if the IRS suspects underreported income

If the IRS suspects you reported less income than you actually earned — specifically, if it believes you left off 25 percent or more of your gross income — it can examine your return for six years instead of three. This longer window applies to the entire return, not just the income section.

You will not know the IRS suspects this until it contacts you, so the practical approach is to keep records for six years if you are self-employed, receive cash income, or have multiple income sources. If you receive a W-2 from an employer, the IRS already has a copy, so underreporting is less likely — but keeping records for six years is still a safe practice.

Seven years for business losses and depreciation

If you claimed a loss on a business, rental property, or investment, keep those records for seven years. The IRS can use a loss to offset income in other years, and it may examine the loss claim years after you file. This applies even if the business is closed or the investment was sold.

Similarly, if you claimed depreciation on business property or rental property, keep the records for seven years. Depreciation reduces your basis in the property, which affects your tax when you sell it. The IRS may ask to see the original cost, the date you placed the property in service, and the depreciation method you used.

Keep property records indefinitely

If you own a home or investment property, keep the purchase documents, closing statement, and receipts for any improvements you made for as long as you own the property, and for at least three years after you sell it. The IRS can examine the gain on a home sale years after the transaction closes.

Home improvements — like a new roof, kitchen remodel, or addition — increase your basis in the home and reduce your taxable gain when you sell. Keep the contractor invoices, receipts, and before-and-after photos. Repairs (fixing a leaky roof) do not increase basis, but improvements (replacing the entire roof) do. If you are unsure whether something counts as an improvement, keep the receipt anyway.

For rental property or investment property, keep all records related to the purchase, improvements, depreciation, and sale indefinitely. These records may be needed if the IRS examines your return years later or if you need to prove your basis for tax purposes.

What to do with old records you no longer need

Once the retention period has passed, you can discard paper documents. For sensitive information — tax returns, bank statements, Social Security numbers — shred the documents or use a document destruction service rather than throwing them in the trash.

Digital records can be deleted, but consider keeping a backup copy of your tax returns in a find location. Many people store old returns in a password-protected folder on their computer or in cloud storage. This costs nothing and takes up minimal space, so there is no harm in keeping them longer than required.

Frequently Asked Questions

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

Copies are fine. The IRS accepts bank statements, credit card statements, digital photos of receipts, and email confirmations as proof of expenses. You do not need to keep the original paper receipt unless you want to for your own records.

What if I filed an extension — does that change how long I keep records?

No. The three-year or six-year window starts from the date you actually filed your return, not from the original April important date. If you filed an extension and submitted your return in October, the audit window begins in October, not April.

Do I need to keep pay stubs if I have a W-2?

No. The W-2 is the official record of your wages, and the IRS has a copy. You can discard pay stubs after you verify they match your W-2. However, keep the W-2 itself for at least three years.

How long do I keep records if I was never audited?

Keep them for the full retention period anyway. The fact that you were not audited in the past does not mean you will not be audited in the future. The IRS can select returns at random or based on specific issues, regardless of your history.

Can I store records digitally instead of keeping paper copies?

Yes. Scanning receipts and storing them in a folder on your computer or in cloud storage is acceptable. Make sure the digital files are legible and that you have a backup in case your device fails. Many people keep both digital and paper copies for important documents like the purchase deed for a home.
