What the Child Tax Credit Is Worth in 2026
Maria and James have two kids, ages 6 and 9. Combined, they earn $95,000 and file jointly. They assume the Child Tax Credit knocks a vague amount off their tax bill, so they never plan around it. They have heard the number $2,000 thrown around, heard it might be more, and left it at that. Then they run the actual figures.
For 2026, the Child Tax Credit is worth up to $2,200 per qualifying child under 17. Two kids means a potential $4,400 reduction in what Maria and James owe. That is not a deduction that trims their taxable income by a few hundred dollars. It is a credit that comes off their tax bill dollar for dollar. If they owed $7,000 in federal tax before the credit, $4,400 of it can disappear, leaving $2,600.
Here is the part most families miss. A credit is only the headline number if you actually owe enough tax to absorb it. The non-refundable portion of the Child Tax Credit can reduce your tax bill to $0, but no lower. Once your tax liability hits zero, the regular credit stops helping. Maria and James owe more than 4,400, so they use the full amount. A family that owes only1,000 in tax cannot use a $4,400 credit the same way, and that is exactly where the refundable portion changes the math.
Three things decide your number. First, how many qualifying children you have, each under 17 at the end of the year, claimed as your dependent, living with you more than half the year, and holding a valid Social Security number. Second, your income, because the credit shrinks once you cross a threshold that depends on your filing status. Third, how much tax you owe, because that controls how much of the credit is non-refundable versus refundable. Change any one of those three and your final number moves.
The age cutoff trips up more families than any other rule. The child must be under 17 at the end of the tax year. A child who turns 17 during 2026 does not qualify for the Child Tax Credit that year, even if they were 16 for eleven months. They may still count for the smaller Credit for Other Dependents, but not the $2,200 amount. Parents of teenagers should check the birthday before assuming the credit carries over from last year.
The 2026 amounts were locked in by the One Big Beautiful Bill Act, which made the $2,200 per-child credit permanent and started annual inflation indexing with the 2026 return. That stability matters. For years the Child Tax Credit was a moving target, scheduled to drop and then extended at the last minute, which made planning nearly impossible. Knowing your number lets you plan withholding, estimated payments, and your expected refund instead of guessing in April. Enter your filing status, income, and the number of qualifying children above, and you will see your estimated credit, any phase-out reduction, and how much could come back as a refund.
