The American Rescue Plan expanded the Child Tax Credit (CTC). As a result, most families, even those with little to-no income, can receive the full amount. That amount is now $300 per month per child under age 6, and $250 for each child age 6 to 17. You can now receive half of the total credit amount in advance monthly payments through December 2021. You can claim the other half when you file your 2021 income tax return.
