The IRS is sending about 1 million eligible American taxpayers a payment this month for the pandemic-era Recovery Rebate Credit that they didn't claim on their 2021 tax returns.

The IRS will send out a total of $2.4 billion in "special payments" to 1 million people who did not claim federal stimulus checks on their tax returns for 2021.

The Internal Revenue Service, IRS, will mail checks worth up to $1,400 to taxpayers who did not claim their stimulus checks during the COVID-19 pandemic. Around one million U.S. taxpayers who were eligible for the check can expect a lump sum mailed to them during tax season.
