A million taxpayers will soon receive up to $1,400 from the IRS. Who are they?

The IRS has announced a plan to distribute Recovery Rebate Credits to 1,000,000 individuals who did not receive their Economic Impact Payments. Each eligible person can receive up to $1400, with payments totaling approximately $2.4 billion. These payments will be sent automatically via direct deposit or paper check. Taxpayers who have not filed their 2021 tax returns may also be eligible, but they must file by April 15th to claim the credit.
