The megabill increased the maximum credit amount from $2,000 to $2,200 for 2025 and indexed the amount for inflation starting in 2026.
[20] Making the credit partially refundable means that families whose credit exceeds their tax liability can receive part of the credit as a refund. The 2017 tax law increased the maximum credit to $2,000 per child for those with sufficient tax liability but introduced a $1,400-per-child (indexed for inflation) cap on the amount families could receive as a refund.
[21] The bipartisan legislation phased-in changes to the Child Tax Credit over three years: 2023-2025. We use the proposed parameters for 2025 to calculate the credit amount for this example.
[22] This figure overstates the number of children affected by not accounting for families' income but understates the number of children affected by counting only U.S. citizen children. (Children who are lawfully present and have an SSN but who do not have at least one parent with an SSN will also lose eligibility.)
