The IRS generally gives you three years to amend a return or claim a refund, so keep your tax documents for at least that long

The answer depends on what you're keeping and why. For most people, three years is the baseline: that's how long the IRS can audit you for unpaid taxes on a return you filed. But the real answer is more complicated, because different documents serve different purposes, and some situations demand you keep records much longer.

If you underreported your income by 25 percent or more, the IRS can go back six years. If you didn't file a return at all, there is no time limit — they can audit you indefinitely. And if you're claiming deductions tied to property, investments, or business expenses, you may need to keep those documents for seven years or longer, even though the tax return itself is only three years old.

The safest approach is to sort your documents by type and keep them according to what each one proves, not just how old your return is.

Key Takeaways

  • Keep tax returns and supporting documents for at least three years, since that is the standard IRS audit window for most returns.
  • The IRS can go back six years if you underreported income by 25 percent or more, and indefinitely if you never filed a return.
  • Documents tied to property, investments, or business assets may need to be kept for seven years or longer, even after the return is three years old.
  • Once you sell an asset or close an account, you can usually discard the supporting documents three years after you file the return that reports the sale or closure.

Why Three Years Is the Standard Retention Period

The three-year rule comes from the statute of limitations on tax assessments. If you file a return on April 15, 2024, the IRS has until April 15, 2027, to assess additional tax on that return — meaning to send you a bill for unpaid taxes. After that date, they generally cannot go back and demand more money based on what was on that return.

This does not mean the IRS forgets about you after three years. It means they cannot assess tax on the specific return you filed. If they discover fraud or a pattern of underreporting across multiple years, they can still pursue older returns. But for a straightforward return with no red flags, three years is the window.

Keep your actual tax return (the Form 1040 and any schedules you filed) for at least three years. Keep receipts, bank statements, and other documents that support the numbers on that return for the same period. Once three years have passed and you have not heard from the IRS, you can safely discard them — unless those documents also support a claim you made that extends beyond that return.

When You Need to Keep Documents Longer Than Three Years

Several situations require you to hold onto records past the three-year mark. The most common is property ownership. If you own a home, rental property, or investment real estate, keep all purchase documents, improvement receipts, and closing statements for as long as you own the property, plus three years after you sell it. The IRS uses these to calculate your cost basis — the amount you paid — which determines how much gain you owe tax on when you sell.

The same rule applies to stocks, bonds, and other investments. Keep purchase confirmations and statements showing your cost basis for three years after you sell. If you inherited an asset, keep the inheritance documents and the valuation used for tax purposes indefinitely, because the IRS may question the basis you claimed years later.

Business owners and self-employed people should keep records for seven years. The IRS has a longer audit window for business returns, and business deductions are scrutinized more closely than personal ones. This includes invoices, receipts, mileage logs, and payroll records.

If you claim a loss on a return — whether from a bad investment, a casualty, or a business — keep the supporting documents for seven years. The IRS treats losses differently from income and may audit them more aggressively.

Documents to Discard After Three Years (Usually)

Once three years have passed since you filed a return, you can usually throw away the following items: pay stubs from that year, bank statements that only show deposits and withdrawals (not tied to a deduction or loss), utility bills, credit card statements used only to track spending, and receipts for small purchases that were not itemized deductions.

The key word is "usually." If a document supports something you will claim on a future return — like the cost basis of an investment you still own, or a loss you are carrying forward — keep it longer. If you are unsure whether a document supports a current claim, err on the side of keeping it.

Mortgage statements, property tax bills, and homeowner insurance bills can be discarded once three years have passed, unless you are still using them to calculate itemized deductions on your current return. If you itemize, keep them through the current tax year plus three more.

What Happens If You Throw Documents Away Too Soon

If the IRS audits you and you cannot produce the documents that support a deduction or income figure, the IRS will disallow it. You will owe the tax plus interest and possibly penalties. This is why the three-year rule is a minimum, not a target.

If you are audited within three years of filing, you must have the documents. If you are audited after three years have passed, the IRS is working outside the normal statute of limitations, which means they suspect a serious problem — underreporting of 25 percent or more, fraud, or a missing return. In those cases, the documents you kept become even more important, because they are your only defense.

The safest approach is to keep documents in a safe place — a filing cabinet, a safe deposit box, or a scanned digital archive — rather than throwing them away on a schedule. The cost of storage is far lower than the cost of losing a deduction you cannot prove.

Digital Storage and Scanned Records

You do not have to keep paper originals. The IRS accepts digital copies, photographs, and scanned documents as long as they are clear and complete. Many people photograph receipts with their phone, store them in a folder, and discard the paper after a year or two.

If you use digital storage, make sure your system is backed up and will still be readable in three to seven years. Cloud storage services like Google Drive, Dropbox, or OneDrive are reliable for this purpose. Avoid storing documents only on your computer's hard drive, which can fail.

Keep a separate folder for each tax year, and include a copy of the actual return you filed (the one you sent to the IRS, not a draft). This makes it straightforward to find what you need if you are ever asked to produce it.

Special Situations: Audits, Amended Returns, and Unfiled Years

If the IRS has opened an audit on your return, do not discard any documents related to that return until the audit is closed and the statute of limitations has run. The same applies if you have filed an amended return (Form 1040-X). Keep documents for three years after the amended return is filed.

If you discover you never filed a return for a particular year, the statute of limitations does not start until you file it. Keep all documents for that year indefinitely, or at least until you file the return and three more years have passed. The IRS can assess tax on an unfiled return at any time.

If you received a notice from the IRS that you owe back taxes or that they are examining a return, keep all related documents until the matter is fully resolved and the time to appeal has passed.

Frequently Asked Questions

Can I throw away my tax return after I file it electronically?

No. Keep a copy of the return you actually filed (the confirmation from your tax software or tax preparer) for at least three years. The IRS has a record of what you filed, but you need your own copy to respond if they question anything on that return or to file an amended return if you made a mistake.

How long should I keep receipts for charitable donations?

Keep them for three years after you file the return that claims the deduction. If you donate to the same charity every year, keep a running list with dates and amounts, and keep receipts for three years from the most recent donation on that return.

What if I lost documents the IRS is asking for?

Tell the IRS you no longer have them. Provide whatever documentation you do have — bank statements, credit card statements, or written explanations of what the documents showed. The IRS may disallow the deduction, but they cannot penalize you for losing documents, only for not having them when asked.

Do I need to keep documents for returns I filed more than seven years ago?

Generally no, unless those returns involved property, investments, or business assets you still own. If you sold a rental property in 2020 and claimed a loss, keep those documents through 2027 (seven years from the return). Once you have sold all assets tied to an old return, you can discard the documents three years after the sale is reported.

Should I keep my tax return forever?

Keeping a copy of your actual tax return (not the supporting documents) forever is a good idea. It costs nothing and can be useful for Social Security verification, mortgage applications, or proving your income history. The supporting documents can be discarded after three to seven years, but the return itself is harmless to keep.
