2026 Child Tax Credit: Qualifying Children and Refund Estimates
For tax year 2026, the Child Tax Credit can be worth up to $2,200 per qualifying child. Eligibility, income limits and refundability rules determine the amount that reaches a return.
Key takeaway: Count only children who meet the IRS qualifying-child rules, and treat a quick credit estimate as preliminary when income is high or refundable-credit rules matter.
What the calculator estimates
The ToolsFA calculator applies a simplified credit of up to $2,200 for each entered qualifying child, limited by estimated federal income tax. It does not calculate the refundable Additional Child Tax Credit.
This design avoids presenting a refundable amount without the earned-income and eligibility details needed for a fuller calculation.

A qualifying child is more than a headcount
The IRS applies tests involving age, relationship, support, residence, dependency and a valid Social Security number. A child may qualify for another dependent-related benefit under different rules, so do not assume every dependant produces the same credit.
- ✓ Check age and relationship
- ✓ Check residence and support
- ✓ Confirm dependency eligibility
- ✓ Confirm the required Social Security number

Income limits and refundability
The credit can phase down at higher income levels. A portion may be refundable through the Additional Child Tax Credit when its separate requirements are satisfied.
Compare the calculator result with current IRS credit guidance before filing, especially for shared custody, recently issued Social Security numbers or high income.
Example: Two qualifying children could produce a simplified credit of up to $4,400 before income phase-outs and the calculator's nonrefundable limit.
