If you viewed or downloaded the 2023 Publication 17 before March 19, 2024, please be advised that on page 2, under Child tax credit (CTC) enhancements have expired, in the Reminders section, the first bullet has been revised as follows. The enhanced credit allowed for qualifying children under age 6 and children under age 18 has expired. For 2023, the initial amount of the CTC is $2,000 for each qualifying child. The credit amount begins to phase out where modified AGI income exceeds $200,000 ($400,000 in the case of a joint return). The amount of the CTC that can be claimed as a refundable credit is limited as it was in 2020 except that the maximum ACTC amount for each qualifying child increased to $1,600.
