The IRS estimates that there is over a billion dollars in unclaimed funds owed to a million taxpayers.

Yes. A million people who were eligible for a stimulus check did not get one.

All because they didn’t file their 2021 tax return.

If you didn’t get a stimulus check in 2021 but were eligible for one, you have until tax day in 2025 to file your 2021 tax return and get it as a Recovery Rebate Credit. As of this writing, that day is a mere eight days away – April 15th, 2025.

When the stimulus check was issued, it was only sent to people who had filed their 2021 tax return and known by the IRS to be eligible for it. If you didn’t file a 2021 tax return, the IRS didn’t know you should’ve gotten a check. Even if you were eligible, you didn’t get one because the IRS didn’t know!

Many citizens don’t file tax returns for a variety of reasons – low income, living off Social Security or other benefits, lack of stable housing, or some other reason. But if you don’t file, you couldn’t get the check.

Fortunately, you have five years to file a tax return. If you were due a refund, which is how the stimulus check is treated under tax law, you forfeit refunds over three years old.

By filing today, if eligible, you could get a check that’s due to you.

If you don’t file a return and were eligible, there’s no way to get the check.

Who was eligible?

First, you have to be a U.S. citizen or U.S. resident alien with a Social Security number and you are not claimed as a dependent on someone else’s tax return.

Next, you were eligible for the full stimulus check if your adjusted gross income (AGI) was:

• Single filers – $75,000 or less
• Head of household – $112,500 or less
• Married filing jointly – $150,000 or less

If you earned more than that, you could still get a partial stimulus check because the amount was phased out.

You also received additional funds for qualifying dependent children of $1,400 each. This was a big jump from previous checks, which added only $500/$600 for qualifying dependent children under 17.

Who should check their eligible?

If you didn’t receive a check and believe you fall within those income and eligibility limits, you should check to see if you were eligible.

If you don’t remember, you can check to see if you received one at the IRS website.

As I mentioned earlier, there is very little time because you forfeit refunds if you don’t file within three years.
