Keep tax returns and supporting documents for at least three years from the date you filed

The IRS standard is three years. If you filed your 2021 return on April 15, 2022, keep those records through April 15, 2025. This covers the period during which the IRS can audit your return and ask you to prove what you reported.

Three years is the baseline, but the actual time you need to keep records depends on your situation. Some people need to hold onto documents longer. Some circumstances extend the important date significantly. The worst outcome of throwing away records too early is having no proof when the IRS questions a deduction or income figure you claimed.

Key Takeaways

  • The IRS can audit your return within three years of filing, so keep tax returns and receipts, bank statements, and other proof for at least that long.
  • If you underreported income by 25 percent or more, the IRS has six years to audit you, so keep records for six years in that case.
  • If you claim a loss from a worthless security or bad debt, keep records indefinitely because there is no statute of limitations on those items.
  • Keep records in a form you can access — paper folders, a filing cabinet, or scanned PDFs all work, as long as you can produce them if asked.
  • The IRS does not require you to keep the actual paper return; a copy or the filed version from your tax software is sufficient proof.

The three-year rule and what it covers

Three years is the standard statute of limitations for an IRS audit. This means the IRS has three years from the date you filed to examine your return and request documentation. After three years passes, the IRS generally cannot go back and challenge what you reported, with rare exceptions.

During those three years, keep everything that supports the numbers on your return: W-2 forms, 1099 forms, receipts for deductions, bank statements showing deposits, mortgage interest statements, charitable donation records, medical expense receipts, and business expense documentation. If you took the standard deduction instead of itemizing, you still need to keep records that prove your income was reported correctly.

The three-year window starts from the date you filed, not from the tax year itself. If you filed your 2023 return on February 1, 2024, the three-year period runs until February 1, 2027. If you filed late — say, in October 2024 — the clock starts from October 2024, not from April 15.

When you need to keep records for six years

The IRS extends the audit period to six years if you underreported income by 25 percent or more. This is a substantial underreporting. If your actual income was $100,000 and you reported only $75,000 or less, the six-year rule applies.

The IRS does not announce this rule upfront — it becomes relevant only if an audit happens and the IRS discovers the underreporting. Once they do, they can go back six years instead of three. This is why keeping records for six years is safer if you are uncertain whether you reported all your income correctly.

Business owners, self-employed people, and anyone with multiple income sources should consider the six-year timeline as a practical standard, since the risk of an unintentional underreporting is higher with complex returns.

Indefinite record-keeping for specific items

Some tax situations have no statute of limitations. If you claim a loss from a worthless security — a stock or bond that became completely valueless — keep those records indefinitely. The same applies to bad debt deductions, where you lent money to someone who never repaid it and you are claiming it as a loss.

For these items, there is no time limit on how far back the IRS can question your claim. Keep the original documentation showing the security was worthless or the debt was uncollectible, along with any correspondence or evidence supporting that information.

If you are unsure whether an item falls into this category, err on the side of keeping the records. The cost of storage is minimal compared to the cost of not having proof if the IRS asks.

What documents to actually keep

You do not need to keep the printed tax return itself, though many people do. What matters is that you can prove what you reported. If you filed electronically through tax software, you have a copy in your account or email. If you filed on paper, keep a copy of the pages you signed.

The supporting documents are what the IRS actually wants to see: receipts, invoices, bank statements, pay stubs, 1099 forms, mortgage statements, donation receipts, medical bills, and any other paper that shows where the numbers came from. For business expenses, keep records of what was purchased, when, how much it cost, and what business purpose it served.

You can store these as paper copies in a folder or filing cabinet, or scan them and keep digital copies. The IRS accepts both. If you scan, make sure the image is clear enough to read all the details. Many people use a combination — digital copies for straightforward searching, paper originals in a box in case the IRS wants to see the actual document.

How to organize records for straightforward retrieval

Organize by tax year and by category. Create a folder — physical or digital — for each year. Inside, separate documents into groups: income documents (W-2s, 1099s), deductions (receipts, invoices), and anything else specific to your situation.

Label clearly. Write the year and category on the folder. If storing digitally, use a naming system that includes the year and type of document. This takes a few minutes when you file but saves hours if you need to find something three years later.

Keep the records in a safe, accessible place. A filing cabinet in your home office works. A plastic storage box in a closet works. A cloud storage folder with scanned copies works. The goal is that you can find what you need without digging through years of paper.

What happens if you cannot find a record

If the IRS audits you and you cannot locate a receipt or document, you are not automatically out of luck. You can reconstruct some information using bank statements, credit card statements, or other secondary evidence. If you paid a contractor by check, the canceled check shows the amount and date even if you lost the invoice.

However, reconstruction is harder and takes longer than having the original. The IRS may accept it, or they may disallow the deduction because you cannot prove it was legitimate. This is why keeping records from the start is far easier than trying to rebuild them later.

If you are audited and realize you are missing documents, tell the IRS when ready. Provide what you do have and explain what is missing. Honesty and effort to cooperate usually result in a better outcome than silence or defensiveness.

Frequently Asked Questions

Do I need to keep receipts if I took the standard deduction?

You do not need receipts to claim the standard deduction itself — that is a fixed amount. However, keep records that prove your income was reported correctly, such as W-2s and 1099s. If the IRS audits and questions your income, you will need to show where that money came from.

Can I throw away records after three years if I am not self-employed?

Three years is safe for most W-2 employees with straightforward returns. However, if you claimed deductions, charitable donations, or medical expenses, and you are uncertain whether you reported everything correctly, keeping records for six years is a safer choice. When in doubt, keep them longer.

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

Filing an amended return (Form 1040-X) does not restart the three-year period from scratch. The IRS can audit the amended return within three years of filing the amendment, but they can also go back and audit the original return if it is still within the original three-year window. Keep records for at least three years from the date you filed the original return.

Is it safe to scan tax records and throw away the paper copies?

Yes, as long as the scans are clear and legible. The IRS accepts digital copies. Make sure you back up your digital files — store them in at least two places, such as an external hard drive and a cloud service. If your only copy is on your computer and the hard drive fails, you have lost the records.

Do I need to keep records for returns I filed more than three years ago?

If three years have passed and you have no reason to think the IRS will audit, you can discard most records. However, keep records for any year in which you claimed a loss from a worthless security or bad debt, since those have no time limit. Also, if you are currently under audit or the IRS has contacted you about a specific year, keep all records for that year.
