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.

USA Child Tax Credit Details for 2026

$2,000 Per Child

Each qualifying child under age 17 earns a $2,000 credit on your USA federal tax return. This directly reduces your tax bill dollar-for-dollar.

$1,700 Refundable (ACTC)

Up to $1,700 of the CTC is refundable for Americans — meaning you receive this as a refund even if you owe zero federal tax.

Income Phaseout

For American families, the CTC begins to phase out at $200,000 MAGI (single) or $400,000 (married filing jointly), reducing by $50 per $1,000 above the threshold.

$500 Other Dependent Credit

American taxpayers with dependents who don't qualify for the full CTC (children 17+, elderly parents) can claim a $500 non-refundable credit per dependent.

USA Child Tax Credit Tips

Ensure each qualifying child has a valid Social Security Number (SSN) issued before the tax filing deadline — ITINs do not qualify for the USA CTC.
The CTC is claimed on Schedule 8812 of your USA Form 1040 — make sure to file this form to receive your credit.
If your USA income is too low to owe federal tax, you can still receive the refundable ACTC portion (up to $1,700 per child).
Consider adjusting your W-4 withholdings to account for the CTC — this can increase your take-home pay throughout the year instead of waiting for a large refund.
The USA CTC phaseout is relatively generous — married couples filing jointly don't lose any credit until AGI exceeds $400,000.
