Keep federal tax records for at least three years

The Internal Revenue Service (IRS) generally expects you to keep tax records for three years from the date you file your return or the return's due date, whichever is later. This three-year window covers most routine audits and allows the IRS to verify the income, deductions, and credits you reported.

The three-year rule applies to supporting documents as well: receipts, invoices, bank statements, cancelled checks, and any other papers that back up the numbers on your return. If you file early, the clock starts from the return's official due date, not the day you submitted it. For example, if you file your 2023 return in February 2024, the three-year period runs from April 15, 2024.

Key Takeaways

  • Keep all tax records and supporting documents for at least three years from your return's due date, which covers most IRS audits.
  • Extend your record-keeping to six years if you underreported income by 25 percent or more, or if you have no record of filing at all.
  • Keep records indefinitely for property you own, including home purchase documents, improvements, and sale records, because they affect future tax liability.
  • State tax agencies may have different timelines than the IRS, so check your state's requirements if you file a state return.
  • Store originals in a safe place and consider keeping digital copies or scans as a backup in case of loss or damage.

When to keep records for six years instead of three

The IRS can go back further than three years in specific situations. If you underreported your income by 25 percent or more, the agency has six years to audit you. This means you should keep those records for six years from the return's due date. The six-year rule also applies if you never filed a return at all for a given year — there is no statute of limitations on a return that was never submitted.

You may not know at the time of filing whether you have underreported by that threshold. If you discover an error later, it is safer to keep records for six years rather than three. The cost of storage is small compared to the cost of not having documentation if the IRS comes looking.

Property records and home improvements have no expiration date

Tax records related to property ownership should be kept indefinitely. This includes the deed or purchase agreement for your home, receipts for major improvements (a new roof, kitchen renovation, or addition), and the closing statement from the sale of a property. These documents determine your cost basis — what you originally paid plus the cost of improvements — which directly affects how much tax you owe when you sell.

If you sell a home five years after buying it, you need the original purchase price and records of any improvements to calculate your capital gain. If you sell ten years later, you still need those same documents. Keep them for as long as you own the property, and for at least three years after you sell it in case questions arise about the sale price or deductions you claimed.

State tax records may require a different timeline

Some states have their own record-keeping rules that differ from federal requirements. Many states follow the three-year federal standard, but others require five or seven years. A few states have no specific requirement but may audit returns within a longer window than the IRS.

If you file a state return, check your state's tax agency website or contact them directly to learn the requirement. Keeping federal records for six years covers most state timelines, but it is worth confirming. States that have income tax include California, New York, Illinois, Texas (limited), and most others — your state's department of revenue or taxation can tell you what applies to you.

What documents to keep and how to store them

Keep the actual tax return itself (the form you filed), all supporting schedules, and every document that backs up the numbers on that return. This includes W-2s and 1099s from employers and financial institutions, receipts for charitable donations, medical expense records, business expense documentation, mortgage interest statements, property tax bills, and investment statements showing gains or losses.

Store originals in a safe, dry place — a filing cabinet, safe deposit box, or home safe works well. Consider making digital copies or scans and storing them separately, either on an external hard drive kept in a different location or in cloud storage. Digital backups protect you if the originals are lost to fire, flood, or theft. Label files clearly with the tax year so you can find what you need quickly if you are audited.

What happens if you cannot find a record

If the IRS audits you and you cannot locate a receipt or document, the audit does not automatically fail. You can reconstruct records using bank statements, credit card statements, or other evidence that shows the transaction occurred. The IRS understands that people lose documents over time.

However, having the original receipt or invoice is always stronger than reconstructing it later. If you are missing records and the IRS contacts you, be honest about what you have and what you do not. Provide whatever documentation you do have, and explain what is missing and why. The IRS is more likely to work with you if you are cooperative than if you appear to be hiding something.

Frequently Asked Questions

Do I need to keep receipts if I have a credit card statement?

A credit card statement shows that a transaction occurred and how much you spent, but it does not always show what you bought. For deductions like business expenses or charitable donations, the IRS prefers itemized receipts that describe what the purchase was for. Keep both the statement and the receipt if possible. If you only have the statement, it is better than nothing, but a detailed receipt is stronger proof.

Can I throw away records after three years?

You can discard most records after three years from your return's due date, with the exception of property records, which you should keep indefinitely. Before you throw anything away, make sure the three-year window has actually closed — count from the return's due date, not the date you filed. If you are unsure whether you have been audited or if there are any open questions about a return, hold onto the records a bit longer.

What if I filed an amended return?

An amended return (Form 1040-X) starts its own three-year clock from the date you file it, not from the original return's due date. Keep records for three years from the amended return's filing date. If you filed an amended return and then the IRS audits you, they may look at both the original and amended returns, so keep supporting documents for both.

Should I keep digital records or paper records?

Either format is acceptable to the IRS as long as the records are legible and complete. Digital copies are easier to store and back up, but make sure you can still open the files years later — avoid formats that may become obsolete. Keeping both a paper copy and a digital copy gives you the most protection against loss.

Do I need to keep records for years I did not file a return?

If you did not file a return for a given year and the IRS has not contacted you about it, there is technically no statute of limitations — they can go back indefinitely. However, the IRS typically focuses on recent years. If you think you should have filed but did not, consider filing a late return and keeping records for at least six years from the date you file it.
