No, the third economic impact payment in 2021 will not include an additional amount for these children because the third round of payments is based on information from your 2020 or 2019 tax return. If the child is your dependent in 2021, you may claim a 2021 Recovery Rebate Credit for the child, if you’re eligible for the credit, on your 2021 tax return that you will file in 2022.
