Keep tax records for at least three years after you file

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 covers the period during which the IRS can assess additional tax on your return.

However, three years is a minimum, not a rule that applies to everyone. The actual time you should keep records depends on what the records are, whether you reported all your income, and whether you made certain kinds of claims. Keeping records longer than three years costs you nothing and protects you against the less common situations where the IRS has more time to act.

Key Takeaways

  • Keep all tax records for at least three years from the filing date, because the IRS can audit returns within that window.
  • Keep records for six years if you reported less than 75 percent of your income on your return, because the IRS has twice as long to assess tax in that case.
  • Keep records indefinitely for any year in which you claimed a loss carryforward or a bad debt deduction, because those claims affect future years' returns.
  • Records include receipts, invoices, bank statements, cancelled checks, and any document that supports a number on your return.
  • If you filed a return late or did not file at all, the three-year clock starts from the date you actually filed, not from the original due date.

When the IRS has six years to audit you

The IRS can go back six years instead of three if you underreported your income by 25 percent or more. This is a high threshold — it means you reported less than 75 percent of the income you actually received. If you made an honest mistake on a small item, you will not hit this mark. If you omitted a large source of income, you will.

The six-year rule applies to the entire return, not just the income you underreported. Once the IRS determines that you underreported by 25 percent or more, they can examine any part of that year's return. This is why keeping records for six years is safer than relying on the three-year rule — you may not know whether the IRS will view your situation as a 25 percent underreport until they contact you.

When to keep records indefinitely

Some tax situations require you to keep records for much longer than three or six years. Keep records indefinitely for any year in which you claimed a loss carryforward, a bad debt deduction, or a worthless security deduction. These deductions carry forward to future years and affect the tax you owe in those years. If the IRS audits a later year and questions whether you were may have access to to the carryforward, you will need the original records to prove it.

Similarly, keep records for the life of any asset you own. If you claimed depreciation on business property or rental property, the IRS can question that depreciation in any year you still own the asset or in the year you sell it. The records that show what you paid for the asset, when you placed it in service, and how much you have depreciated it are the only proof you have.

If you received an extension to file your return, keep records for at least three years from the date you actually filed, not from the original April 15 important date. The same applies if you filed late without an extension — the three-year window runs from the date the IRS received your return.

What documents count as tax records

Tax records are any document that supports a number on your return. For income, this includes W-2 forms, 1099 forms, bank statements, brokerage statements, and invoices or receipts showing money you received. For deductions, keep receipts, invoices, cancelled checks, credit card statements, and mileage logs — anything that shows you spent the money you claimed.

For business owners and self-employed people, records also include ledgers, profit-and-loss statements, payroll records, and any document showing business income or expenses. For rental property, keep records of repairs, maintenance, property taxes, insurance, and mortgage interest. For investments, keep statements showing your cost basis, dividends received, and gains or losses when you sold.

You do not have to keep the original paper documents. The IRS accepts digital copies, scans, and photographs of receipts, as long as the image is clear and shows all the information on the original. Many people photograph receipts with their phone and store them in a folder on their computer or in cloud storage. This method works as long as you can produce the image if the IRS asks.

How to organize records for straightforward retrieval

Organize your records by year and by category — income, deductions, property, investments, and so on. This makes it much faster to find what you need if the IRS contacts you or if you need to amend a return. A straightforward folder system, either physical or digital, works well: one folder per tax year, with subfolders for each type of record.

If you use tax software or work with a tax preparer, ask them what records they need and in what format. Some preparers want digital copies uploaded to a portal; others want paper originals. Knowing this in advance saves time when you are gathering documents.

Label folders and files clearly with the year and category. Do not rely on memory to know which folder holds 2022 business expenses or 2021 rental income. A clear label takes seconds to write and saves hours of searching later.

What happens if you cannot find a record

If the IRS audits you and you cannot find a receipt or supporting document, you are not automatically out of luck. The IRS recognizes that some records are lost or destroyed. You can reconstruct the amount using other evidence — bank statements, credit card statements, cancelled checks, or even a written statement from the person or business you paid.

The stronger your other evidence, the better your position. A bank statement showing a withdrawal for the exact amount you claimed is strong evidence. A vague memory that you spent money on something is not. If you are missing records for a large deduction, the IRS is more likely to disallow it or reduce it than if the amount is small.

This is another reason to keep records longer than the minimum. The longer you keep them, the less likely you are to face this problem. Many people keep tax records for seven to ten years as a practical matter, even though the law does not require it.

Frequently Asked Questions

Do I have to keep records if I did not itemize deductions?

Yes. Even if you took the standard deduction, the IRS can still audit your return and ask you to prove the income you reported. Keep records that show your income — W-2s, 1099s, bank statements, and any other document showing money you received. You do not need receipts for deductions you did not claim, but you do need proof of income.

Can I throw away records after three years?

You can, but it is safer to keep them longer. Three years is the minimum for most situations, but six years applies if you underreported income, and indefinitely applies if you claimed a loss carryforward or depreciation. If you are not sure which rule applies to you, keeping records for seven years covers most situations without taking up much space.

What if I filed an amended return?

Keep records for three years from the date you filed the amended return, not from the date you filed the original. The IRS can audit an amended return within three years of the date you filed it. If you filed an amended return in 2024, keep those records through 2027.

Do I need to keep records for returns I did not file?

If you did not file a return for a particular year, the IRS has no time limit to assess tax. However, they rarely go back more than six years in practice. If you are considering filing a return for an unfiled year, consult a tax professional first — there may be penalties, but there may also be refunds owed to you.

Can I store records digitally instead of on paper?

Yes. Digital copies, scans, and photographs are acceptable to the IRS as long as they are clear and show all the information on the original document. Store digital records in a safe location — either on your computer with a backup, or in cloud storage. Make sure you can access them years later if you need to.
