If you’ve been putting off filing your 2021 federal tax return, you could be missing out on more than just a tax refund—you might also be leaving COVID-era stimulus money on the table.
According to the Internal Revenue Service (IRS), millions of Americans are still eligible to receive the Recovery Rebate Credit (RRC)—worth up to $1,400 per person—but only if they submit their 2021 tax return by April 15, 2025.
After this date, the chance to claim that money—and any other unclaimed refunds—expires permanently.

April 15, 2025: Your Final Chance
The IRS has confirmed that the three-year window to claim a refund for the 2021 tax year closes on April 15, 2025. After this deadline, any unclaimed funds will become the property of the U.S. Treasury.
“People may not realize they’re still eligible for a stimulus check or tax refund,” said IRS Commissioner Danny Werfel. “But the time to act is running out.”
What You Could Be Missing
If you didn’t file your 2021 return, here’s what you might still be eligible to receive:
1. Recovery Rebate Credit (Third Stimulus Payment)
The RRC was issued as part of the third round of Economic Impact Payments in 2021. Eligible individuals who didn’t receive the full amount—or any payment at all—can claim it by filing their 2021 return.
- Worth up to $1,400 per person, including dependents.
- Income eligibility phases out above:
- $75,000 for single filers
- $150,000 for married couples filing jointly
- $112,500 for heads of household
2. Earned Income Tax Credit (EITC)
You may also qualify for the Earned Income Tax Credit, worth up to $6,728 depending on your income and family size.
- Available to low-to-moderate income earners.
- You must file a tax return to receive it.
3. Unclaimed Tax Refunds
The IRS reports that over 1.1 million Americans may be owed refunds for 2021, with a median refund of $781.
“A lot of that money could help families pay for essentials like rent, food, and healthcare,” said an IRS spokesperson.

Important Caveats
- The IRS will not issue a 2021 refund if you didn’t file by the April 15, 2025, deadline.
- If you’ve already filed 2022 or 2023 returns and didn’t get the credit, you still need to file 2021 separately to be eligible.
- You can also file a request for extension until October 15, 2025, using Form 4868.
