It's possible that you could still be owed a $1,400 economic impact payment by the Internal Revenue Service, but you have just weeks to claim the money.

According to an IRS statement, an estimated one million people were still owed a $1,400 stimulus check as of the end of 2024. The IRS said it had identified some of the Americans still owed a check and planned on sending them a payment by the end of January.

But if someone didn't file a 2021 tax return, it's possible they were eligible for a check and did not receive one. The IRS said that Americans who did not file a return in 2021 have until April 15 to file an amended return to claim the $1,400 credit.

The IRS said that taxpayers who did not file must submit a tax return, even if their income was minimal or nonexistent, in order to get a stimulus check.
