to happen in 2024. United States The child tax credit is available to taxpayers who have children under the age of 17 (or in 2021 under the age of 18). Since 2018, the CTC is $2,000 per qualifying child. It is available in full to single filers who make up to $200,000 and married couples filing jointly who make up to $400,000. Above these limits, the CTC is phased out at the rate of $50 for each additional $1,000 earned. When a taxpayer's credit value exceeds his or her tax liability, the taxpayer is eligible for the additional child tax credit (ACTC), which is calculated as 15% of the taxpayer's AGI in excess of $2,500 (i.e. a family must make at least $2,500 to be eligible for the credit), with the refund value capped at $1,400. The American Rescue Plan Act (ARP) of 2021 significantly expanded the child tax credit for one year, allowing qualifying families to offset $3,000 per child up to age 17 and $3,600 per child under age 6. It also made the credit fully-refundable and offered the option of receiving half of the credit as six monthly payments. 39 million households, covering 88% of children in the United States, will begin receiving these payments automatically beginning July 15, 2021. The proposed Build Back Better Act would extend the expansion for an additional year and make the full refundability of the CTC permanent. The child tax credit has a significant effect on child poverty. In 2016, it was estimated to have lifted about 3 million children out of poverty. In 2021, a Columbia University study estimated that the expansion of the CTC in the American Rescue Plan Act reduced child poverty by an additional 26%, and would have decreased child poverty by 40% had all eligible households claimed the credit.
