The rule in one sentence
If you did not file a federal tax return and you were owed a refund, you generally have three years from the original filing deadline to file and claim it. After that, the refund is typically lost. This is why checking past years can matter, especially for people whose income was low or who had withholding taken from pay.
How the deadline works
The filing deadline is usually in mid-April. Three years after that date is your cutoff. Examples (assuming the standard April 15 deadline):
| Tax year | Return originally due | Refund claim generally due by |
|---|---|---|
| 2022 | April 18, 2023 | April 18, 2026 |
| 2023 | April 15, 2024 | April 15, 2027 |
| 2024 | April 15, 2025 | April 15, 2028 |
Deadlines can shift for weekends, holidays or disaster relief, so confirm the exact date on IRS.gov.
Who is most likely to be owed
- People with little income who were not required to file but had tax withheld.
- Workers who qualified for credits, such as the Earned Income Tax Credit. See credits you may be missing.
- People who skipped filing because they assumed they owed nothing.
How to file a past return
- Get your income records. If you cannot find W-2s or 1099s, the IRS "Get Transcript" tool provides wage and income information.
- Use the forms and instructions for that specific tax year from IRS.gov.
- File by mail (past-year returns often cannot be e-filed) and keep proof of mailing.
- Use the IRS refund-status tool afterward.
Free help is available through IRS volunteer programs (VITA) for people who qualify.
Uncashed or lost refund checks
If a refund check was lost, stolen or expired, contact the IRS to request a replacement. The IRS refund-status tool can show whether a refund was issued. Update your address with the IRS so future mail reaches you.
Does this apply to state refunds?
States have their own deadlines, which may differ. Check your state revenue department.

Past-year returns often have to be filed on paper. Check the IRS instructions for the year.
What if I lost my W-2?
Use IRS Get Transcript or contact your employer. The IRS can provide wage and income information.
