About this tool
Enter your filing status, income (MAGI), the number of children under 17 and other dependents, your earned income and your tax before credits. The calculator applies the $2,200 credit per child, the $50-per-$1,000 phase-out, the $500 credit for other dependents and the refundable limit.
The rules used
The credit is $2,200 per qualifying child under 17 and $500 per other dependent. It starts to shrink when modified adjusted gross income goes over $200,000 ($400,000 married filing jointly): $50 less for every $1,000 or part of $1,000 above. Each child needs a Social Security number valid for work.
Refundable part
The credit first reduces your tax. If some is left, up to $1,700 per child can be refunded (the Additional Child Tax Credit), limited to 15% of earned income above $2,500.
What it ignores
The credit for other dependents is not refundable and is treated here together with the child credit for the phase-out. Other credits that also use your tax are not modeled.
Worked example
Two children, single filer, income $220,000: the credit is $4,400, income is $20,000 over $200,000, so it falls by $1,000 to $3,400. A single parent with two children, $12,000 of earnings and no tax gets a refundable credit of $1,425 (15% of $9,500).
Tips for best results
Check every box before you rely on a result, because one wrong digit changes the whole answer. Use the exact figures from your payslip, bill, certificate or contract, and keep a note of the date you calculated. Rates, thresholds and rules change from time to time, so for tax, fees and legal matters treat the output as an estimate and confirm with the official source named on this page. You can run as many scenarios as you like; nothing is saved or sent, and refreshing the page clears the boxes.

Is the credit the same in 2025 and 2026?
Yes, $2,200 per child. The refundable amount is limited to $1,700 per child.

No. The child must be under 17 at the end of the year. A 17-year-old may qualify as an other dependent for $500.
Which income do I use for the phase-out?
Modified adjusted gross income. For most people it is adjusted gross income.
Why do I get nothing back?
The refund needs earned income above $2,500, and only the part not used against your tax is refundable.
