Summary: The Child Tax Credit for 2026 is $2,200 per qualifying child, but only $500 of it is guaranteed usable against tax you owe. The other $1,700 is the Additional Child Tax Credit (ACTC), a refundable portion that can be paid to you as a refund even with little or no tax liability. You need at least $2,500 of earned income, and the ACTC equals 15 percent of earned income above $2,500, capped at $1,700 per child. It is claimed on Schedule 8812 attached to Form 1040.
Tax credits come in two flavors, and the distinction decides how much of the Child Tax Credit actually reaches your pocket. A nonrefundable credit can only cut your tax bill down to zero; once your bill is zero, leftover credit is wasted. A refundable credit keeps going past zero and comes back to you as a refund. The Child Tax Credit is a hybrid: $500 of each child's $2,200 is nonrefundable, and up to $1,700 is refundable through a mechanism called the Additional Child Tax Credit, or ACTC.
Think of the $2,200 credit as having two layers. The bottom layer is the nonrefundable Child Tax Credit, worth $500 per qualifying child. It applies against your federal income tax on Schedule 8812 and then on Form 1040. If your tax bill is $800 and your bottom layer is $1,000 (two children), you use $800 and the remaining $200 disappears. Nothing carries forward.
The top layer is the ACTC, worth up to $1,700 per qualifying child. This is the part the IRS can refund to you even if your tax liability is zero. In practice the ACTC is the part of the credit that low income families actually receive as money, while higher income families absorb the whole credit against tax they owe. Both layers phase out together at $50 per $1,000 of income above $200,000 ($400,000 for married filing jointly).
The gate for any refundable amount is earned income. For 2026 you need at least $2,500 of earned income to receive anything through the ACTC. Earned income means wages, salaries, tips, and net self-employment earnings. It does not include Social Security, pensions, unemployment compensation, or investment income.
If your earned income is below $2,500, your entire Child Tax Credit can only be nonrefundable. A family with two children and $2,000 of earned income still gets the credit on paper, but only to the extent they have a tax bill to offset. Families with very low earnings and little tax liability are the ones most affected by this floor.
Above the $2,500 floor, the refundable amount is the smaller of two numbers: 15 percent of your earned income above $2,500, or $1,700 per qualifying child. The formula looks like this:
ACTC = min($1,700 x qualifying children, 15% x (earned income - $2,500))
Families with three or more children have an alternative calculation on Schedule 8812 based on Social Security taxes, which can produce a larger refundable amount. That path is an edge case; most filers use the standard formula.
Example 1: single parent, one child, $30,000 earned income. 15 percent of ($30,000 - $2,500) is $4,125. The cap is $1,700 for one child, so the ACTC is $1,700. The parent's full refundable portion is the maximum; the remaining $500 of the credit reduces any tax owed.
Example 2: married couple, two children, $12,000 earned income. 15 percent of ($12,000 - $2,500) is $1,425. The cap for two children is $3,400, so the ACTC is $1,425. Their total refundable credit is $1,425 even though the headline credit is $4,400, because the ACTC is limited by their earnings.
Example 3: single parent, two children, $2,400 earned income. Below the $2,500 floor, so the ACTC is zero. The parent can still use the $1,000 nonrefundable portion against tax owed, but gets no refund.
Because the ACTC is refundable, refunds that include it are subject to the PATH Act hold: the IRS cannot issue them before mid-February, even if you file in January. The hold applies to the entire refund, not just the ACTC portion. Plan on late February or early March for the money to arrive.
The most expensive mistake is assuming the whole $2,200 per child is refundable. It is not; the refundable ceiling is $1,700 per child, and only with enough earned income. A second mistake is counting unearned income toward the $2,500 floor. A third is forgetting the SSN rule: under the 2025 reconciliation law, you (or your spouse on a joint return) and each qualifying child need a Social Security number valid for employment, issued before the return's due date, to claim the credit at all, refundable or not.
Up to $1,700 per qualifying child for 2026, through the Additional Child Tax Credit (ACTC). The remaining $500 per child is nonrefundable, so it can only reduce tax you owe.
You need at least $2,500 of earned income for the year. The refundable amount is 15 percent of your earned income above $2,500, capped at $1,700 per qualifying child.
No. The $500 Credit for Other Dependents is entirely nonrefundable. If you owe no federal income tax, the other-dependent credit gives you nothing.
You claim it on Schedule 8812, Credits for Qualifying Children and Other Dependents, which you attach to your Form 1040. The form figures the refundable portion from your earned income and carries it to your return as a refundable credit.
