About the Child Tax Credit Estimator

The Child Tax Credit provides up to $2,000 per qualifying child, but the credit phases out for higher earners — reduced by $50 for every $1,000 (or part of $1,000) that income exceeds the applicable threshold.

Formula: Credit Before Phase-Out = Children × $2,000 · Reduction = ceil[(AGI − Threshold) ÷ 1,000] × $50 · Total Credit = max(0, Credit − Reduction)

Thresholds are simplified here at $200,000 for single filers and $400,000 for married filing jointly. This is an estimate only — actual eligibility also depends on the child's age, relationship, residency and additional IRS rules.
