About the US Child Tax Credit Calculator 2026
For 2026 the child tax credit is $2,200 for each child under 17 with a Social Security number, and from 2025 at least one parent also needs an SSN. Up to $1,700 per child is refundable as the additional child tax credit, worked out as 15% of earned income over $2,500.
Other dependents, such as children aged 17 or 18 or a parent you support, give a $500 credit. The credit falls by $50 for every $1,000 of income over $200,000, or $400,000 for married couples filing jointly.
