Free USA Child Tax Credit Calculator — 2026 CTC Estimator
The Child Tax Credit (CTC) is one of the most valuable tax benefits available to American families. For the 2026 tax year, the USA CTC provides up to $2,000 per qualifying child under age 17, with up to $1,700 refundable as the Additional Child Tax Credit (ACTC). The credit begins to phase out for single filers with modified AGI above $200,000 and married filing jointly above $400,000. This free USA Child Tax Credit Calculator helps American parents and guardians estimate their total CTC, determine the refundable vs non-refundable portions, and plan for maximum tax savings on their federal return.
🇺🇸 Understanding the USA Child Tax Credit
The Child Tax Credit directly reduces your USA federal tax bill — up to $2,000 per qualifying child. A qualifying child must be under 17, a US citizen or resident alien, your dependent, and lived with you for more than half the year. The credit is partially refundable: even if you owe zero federal tax, you can receive up to $1,700 back as the Additional Child Tax Credit. For other dependents (children 17+ or elderly parents), a $500 non-refundable 'Other Dependent Credit' is available. The phaseout starts at $200,000 MAGI (single) or $400,000 (married filing jointly), reducing the credit by $50 for every $1,000 above the threshold.
