Millions of Americans could be missing out on more than $1 billion in unclaimed tax refunds from 2021—and time is running out to collect. If you’re owed a refund, especially over $3,000, the IRS has set a hard deadline: May 15, 2025. After that, the money goes to the U.S. Treasury and it’s gone for good. Many of these refunds are tied to refundable tax credits like the Earned Income Tax Credit (EITC), so if you didn’t file in 2021, now’s your last shot.
Overview
Let’s take a look at what’s at stake:
| Feature | Details |
|---|---|
| Refunds Unclaimed | Over 1.1 million taxpayers |
| Total Refund Amount | $1 billion+ |
| Median Refund | Around $781 |
| Possible Refund Over | $3,000 (with EITC or other credits) |
| Claim Deadline | May 15, 2025 |
| Tax Year | 2021 |
So yes, you could be leaving a few thousand dollars on the table just because you didn’t file a return. Let’s fix that.
Why
Why are so many refunds unclaimed? It comes down to a few common reasons:
- People didn’t file because their income was too low to require it.
- Others missed the deadline or didn’t have their documents ready.
- Some didn’t know about credits like EITC that make refunds possible—even if you didn’t owe taxes.
Eligibility
You could be eligible for a tax refund over $3,000 if you fall into one or more of these categories:
Didn’tFile
The IRS says over a million people didn’t file a return for 2021. If you’re one of them, and taxes were withheld or credits apply, you may have money waiting.
EITC
This is the big one. The Earned Income Tax Credit can add thousands to your refund—especially for families. Here are the 2021 limits:
| Qualifying Children | Max Income (Single) | Max Income (Married) |
|---|---|---|
| 3+ Children | $51,464 | $57,414 |
| 2 Children | $47,915 | $53,865 |
| 1 Child | $42,158 | $48,108 |
| No Children | $21,430 | $27,380 |
The maximum EITC for 2021 was $6,728. Even if you didn’t earn much, this credit could easily put your refund over $3,000.
Withholding
If you worked at all in 2021, chances are your employer withheld taxes. You could get some or all of that money back just by filing.
Other Credits
Besides EITC, your refund may include:
- Child Tax Credit
- American Opportunity or Lifetime Learning education credits
- Recovery Rebate Credit if you missed a stimulus payment
Steps
Want to claim your refund? Here’s how to get started:
Step 1
Find your W-2s, 1099s, or any other income records from 2021. If you’ve lost them:
- Ask your employer
- Use the IRS “Get Transcript” tool to request a Wage and Income transcript
Step 2
You must file a 2021 Form 1040—not the current year’s form. Download it from the IRS website or call 800-TAX-FORM to have one mailed.
Step 3
E-filing is no longer available for 2021. You’ll need to paper file your return and mail it to the correct IRS address listed in the instructions.
Step 4
Once your return is processed, track it using the Where’s My Refund? tool on irs.gov/refunds.
Important
Before you rush off to file, a few extra things to keep in mind:
- The IRS might hold your 2021 refund if you haven’t filed 2022 or 2023 returns.
- If you owe debt (like back taxes, child support, or student loans), your refund could be reduced.
- Common mistakes to avoid:
- Filing the wrong year’s form
- Forgetting to sign your return
- Using the wrong mailing address
- Skipping refundable credits
Your 2021 refund could be bigger than you think—especially if EITC or other credits apply. But the window to claim it is closing fast. Don’t let the IRS keep what’s yours. File that return before May 15, 2025.
