The IRS requires you to keep tax records for at least three years, but some situations demand seven years or longer

The three-year rule is the baseline: the Internal Revenue Service can audit your return within three years of the filing date, so you need to keep the documents that support what you reported — receipts, W-2s, 1099s, bank statements, and anything else you used to calculate your income and deductions.

That three years is not a hard stop, though. If you underreported income by more than 25 percent, the IRS has six years. If you did not file a return at all, there is no time limit — they can go back as far as they want. And if you claimed a loss from a worthless security or a bad debt, keep those records for seven years.

State tax agencies often have their own rules, which may be longer or shorter than the federal requirement. Some states follow the IRS timeline; others extend it. If you file in multiple states, you may need to keep records longer for one state than another.

Key Takeaways

  • The IRS standard is three years from the date you file, but six years if you underreported income by 25 percent or more.
  • Worthless securities, bad debts, and certain business losses require seven-year retention under federal rules.
  • State tax agencies set their own retention periods, which vary — check your state's department of revenue website for the exact requirement.
  • If you did not file a return, keep records indefinitely because there is no statute of limitations.
  • Home office deductions, rental property records, and self-employment expenses often trigger longer retention periods because they are audited more frequently.

The three-year federal baseline and when it extends

The three-year window starts from the date you file your return, not the tax year itself. If you file your 2023 return on April 15, 2024, the three-year clock runs until April 15, 2027. If you file late — say, in August 2024 — the clock starts then instead.

The IRS can reopen an audit after three years only if they have reason to believe you made a substantial error. A substantial underreporting means you reported less than 75 percent of your actual income. If you reported $40,000 in income but actually earned $60,000, that is a 33 percent underreporting, which triggers the six-year rule. The IRS does not have to prove fraud; they just have to show the discrepancy was large.

If you filed a return claiming a loss from a worthless security — a stock or bond that became valueless — or a bad debt deduction, federal rules require seven-year retention. The same applies to losses from certain business activities. These categories are audited less often than ordinary income, but when they are, the IRS looks back further.

State-specific retention requirements

Most states align with the federal three-year rule, but not all. California, for example, follows the IRS standard of three years for most returns, but extends it to four years if you underreported income. New York uses three years as well. Illinois, Texas, and Florida have no state income tax, so you only follow federal rules.

Some states are stricter. Maryland requires four years for most records. Massachusetts asks for six years if you claim a business loss. If you operate a business in multiple states, you may end up keeping records for the longest period any of those states requires.

The easiest way to find your state's rule is to visit your state's department of revenue website and search for "record retention" or "how long to keep tax records." Most states publish this information clearly. If you cannot find it, call the department directly — they can tell you in one conversation.

What counts as a tax record

A tax record is anything you used to prepare your return or anything that proves what you reported. This includes W-2s and 1099s from employers and clients, receipts for deductible expenses, bank and credit card statements, mortgage interest statements, property tax bills, charitable donation receipts, medical expense documentation, and mileage logs if you claim a vehicle deduction.

For self-employed people and business owners, records also include invoices you issued, expense receipts, payroll records if you have employees, and documentation of any business assets you depreciated. If you claim a home office deduction, keep the lease or mortgage documents and utility bills that show your home address and the square footage of the office space.

You do not have to keep paper originals. The IRS accepts digital copies, scans, and photographs of receipts. Many people photograph receipts as they spend and store them in a folder on their phone or computer. As long as the image is legible and shows the date, amount, and what was purchased, it counts.

Special situations that require longer retention

If you own rental property, keep records for at least three years after you sell the property, even if that extends beyond the normal three-year window. The IRS may question your basis calculation (what you paid for the property) or your depreciation deductions years after the sale.

Home office deductions are audited more frequently than most deductions, so consider keeping those supporting documents for five to seven years. The same applies if you claim significant charitable donations — the IRS scrutinizes large deductions, and you may need to prove the donation amount and the charity's status.

If you received a notice of deficiency from the IRS or your state, keep all related records until the case is fully resolved, even if that takes longer than the normal retention period. Once the audit is closed and any appeal is finished, you can discard those records after the standard retention period has passed.

How to organize and store tax records

The simplest method is to create a folder for each tax year and put everything in it — the return itself, all supporting documents, receipts, and statements. Label the folder with the year (2023, 2024, and so on) and store it somewhere you can find it quickly if you need it.

For digital storage, use a cloud service like Google Drive, Dropbox, or OneDrive so your records are backed up and accessible from any device. Create subfolders by category: income, deductions, charitable donations, medical expenses. Take photos of paper receipts and file them in the same folder as the digital documents.

Do not throw away records until you are certain the retention period has passed. If you filed your 2021 return in April 2022, you can safely discard those records after April 2025 (three years later), assuming no audit was opened and you did not underreport income.

What to do if you lost records

If you cannot find a receipt or document, do not panic. The IRS does not require you to produce original receipts for every expense under $75, though you do need to show you had the expense. A bank or credit card statement showing the charge is often enough.

For larger expenses or deductions that are commonly audited — charitable donations over $250, business meals, or vehicle expenses — missing documentation is more serious. If you are audited and cannot produce the receipt, the IRS may disallow the deduction. You can try to reconstruct the record by contacting the merchant or your bank, but that takes time.

The best approach is to keep records as you file. If you lost records from a year that is still within the audit window, contact a tax professional who can advise you on what to do if you are audited. If the year is outside the audit window, you can safely discard what you have.

Frequently Asked Questions

Can I throw away my tax records after three years?

Only if you did not underreport income by 25 percent or more and you did not claim worthless securities or bad debt losses. If any of those explore, keep records for six or seven years. Also check your state's rule — some states require longer retention. When in doubt, keep records for seven years.

Do I need to keep the original receipts or are photos okay?

Photos and scans are fine. The IRS accepts digital copies as long as they are legible and show the date, amount, and what was purchased. You do not need to keep paper originals, though many people do for their own records.

What if I am audited — how long do I have to keep records then?

Keep all records related to the audit until the case is completely closed, including any appeals. Once the IRS or your state issues a final information, you can discard those records after the normal retention period has passed from your original filing date.

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

If you did not file, there is no statute of limitations — the IRS can go back as far as they want. Keep records indefinitely for any year you did not file, or until you file a return for that year and the normal retention period expires.

How do I find out what my state requires?

Visit your state's department of revenue website and search for "record retention" or "tax record retention." Most states publish the requirement clearly. If you cannot find it online, call the department directly — they can answer in one call.
