The IRS generally wants you to keep tax returns and records for at least three years from the date you filed

The three-year rule is the baseline. If you filed your 2023 tax return on April 15, 2024, the IRS can audit that return through April 15, 2027. After that window closes, they cannot go back and challenge what you reported.

This three-year period applies to most people in most situations. It covers your actual tax return (the form you signed and filed), plus every receipt, bank statement, mortgage interest statement, charitable donation record, and other document you used to fill it out. The IRS does not need to ask permission to examine your records during those three years — they can simply request them.

You should keep copies of your filed return itself indefinitely, even after three years pass. A copy proves you filed, what you reported, and when. You may need it years later for a mortgage application, a background check, or to prove income to a government program. The return itself takes almost no space to store.

Key Takeaways

  • Keep tax returns and supporting documents for at least three years from the filing date, because the IRS can audit during that window.
  • If you underreported income by 25 percent or more, the IRS can go back six years instead of three.
  • If you did not file a return for a year, there is no time limit — the IRS can audit that year at any point.
  • Keep your actual filed return copy permanently, even after the three-year window closes, because you may need it for loans or government programs.
  • Supporting documents like receipts and statements can be discarded after three years unless they relate to property, investments, or ongoing business expenses.

When the IRS can go back more than three years

The three-year window extends to six years if you underreported your income by 25 percent or more. This is called the "substantial underreporting" rule. If your actual income was $100,000 but you reported only $75,000, you crossed that threshold. The IRS can then examine records from six years back instead of three.

There is no time limit at all if you did not file a return for a particular year. If you never filed a 2020 return, the IRS can audit the 2020 tax year whenever they choose — five years from now, ten years from now, or longer. This is why filing a return, even if you owe nothing, is safer than not filing at all.

Fraud also removes the time limit. If the IRS determines you deliberately falsified records or hid income, they can go back indefinitely. This is rare and requires proof of intent, not just a mistake.

What documents to keep and what you can discard

Keep everything that supports the numbers on your return: W-2 forms, 1099 forms, receipts for deductions, bank statements showing deposits, mortgage statements, property tax records, charitable donation receipts, medical expense records, and business expense logs. If you took the standard deduction instead of itemizing, you still need to keep records that prove your income, even though you did not list individual deductions on the return itself.

After three years, you can discard most supporting documents — receipts for meals, office supplies, or other one-time expenses that will not appear on future returns. However, keep documents related to property you still own. If you bought a house in 2020 and still own it, keep the purchase documents, improvement receipts, and closing statements indefinitely. When you eventually sell, the IRS will want to see what you paid and what you spent to improve it, because those numbers affect your capital gains tax.

Keep investment records (brokerage statements, purchase confirmations, dividend records) for at least three years after you sell the investment. If you sold stock in 2024, keep those records through 2027. If you still own the investment, keep the records indefinitely.

State tax returns and local records

Your state may have a different time limit than the federal three-year rule. Some states follow the federal timeline; others extend to four or five years. A few states have no statute of limitations for tax audits. Check your state's tax agency website or call their helpline to learn the specific window for your state.

Local income taxes (in cities or counties that impose them) usually follow the state rule, but verify with your local tax office. If you live in a state with no income tax, you only need to worry about federal records.

How to organize and store your records

You do not need to keep original paper receipts if you have digital copies. A photograph, a PDF scan, or a download from your bank or credit card company is acceptable to the IRS. Many people photograph receipts as they go, then discard the paper after three years.

Store copies in a way you can retrieve them quickly if audited. A folder for each year (2023 receipts, 2023 statements, 2023 return) works well. If you use tax software or a CPA, ask whether they keep copies — many do, and you can request them if you need them later.

Do not throw away documents on the day the three-year window closes. Audits can take months to complete, and the IRS sometimes requests records after the formal audit period has ended. Keep documents for at least 3.5 years to account for processing delays.

What happens if you do not have a document

If the IRS audits you and you cannot find a receipt or statement, it does not automatically mean you lose the deduction. You can reconstruct records using bank statements, credit card statements, or other evidence. If you claimed $2,000 in charitable donations but lost the receipts, a bank statement showing transfers to charities can support your claim.

However, reconstructing is harder than keeping originals. If you have no evidence at all, the IRS can disallow the deduction. This is why keeping documents during the three-year window matters — it is far easier to show what you spent than to prove it years later.

Frequently Asked Questions

Can I throw away my tax return after three years?

You can discard supporting documents after three years, but keep a copy of your actual filed return permanently. The return itself is proof you filed and what you reported. You may need it for a mortgage, a loan, or to show income to a government program years later.

What if I am self-employed or run a business?

Keep business records for at least three years, same as everyone else. However, keep records related to assets you still use in the business indefinitely — equipment purchases, property improvements, and vehicle records. These affect your depreciation and basis calculations for years to come.

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

A credit card statement showing the charge is usually enough for the IRS. You do not need the original receipt if the statement clearly shows the date, amount, and merchant. However, if the IRS questions whether the expense was actually business-related or deductible, a receipt with more detail can help you explain it.

How long should I keep records if I am being audited right now?

Keep everything until the audit is completely finished and you have received a final information from the IRS. Do not discard documents just because the three-year window has passed if an audit is active. Once the IRS closes the case in writing, you can follow the normal three-year rule going forward.

What if I filed an amended return?

Keep records for three years from the date you filed the amended return, not the original return date. If you filed your 2023 return in April 2024 but amended it in August 2024, the three-year window runs from August 2024, not April 2024.
