The Child Tax Credit is worth up to $2,200 per qualifying child for 2026, and most families never have to think hard about claiming it — it flows automatically once you list a dependent on your return. The details that actually matter are the income phaseout, the refundable portion if you owe little or no tax, and exactly who counts as a qualifying child.

How Much Is the Child Tax Credit in 2026

The maximum credit is $2,200 per qualifying child for 2026. This amount was set by the One Big Beautiful Bill Act (OBBBA), signed in July 2025, which raised the credit from its prior $2,000 level and, unlike the old law, indexes it to inflation going forward so it should tick up slightly in future years rather than reverting downward.

The credit applies per child, not per return, so a family with three qualifying children can claim up to $6,600 total, subject to the income phaseout below.

Income Phaseout Thresholds

You can claim the full credit if your modified adjusted gross income is $200,000 or less as a single filer, or $400,000 or less if you’re married filing jointly. Above those thresholds, the credit is reduced by $50 for every $1,000 (or fraction of $1,000) your income exceeds the limit, until it phases out completely.

For most middle-income families, this phaseout never comes into play. It mainly matters for dual-income professional households or anyone with a large one-time income spike, like a bonus, stock sale, or business sale, in the tax year.

The Refundable Portion: Additional Child Tax Credit

The Child Tax Credit is only partially refundable. If your tax liability is smaller than your total credit, up to $1,700 per child can come back to you as a refund through the Additional Child Tax Credit (ACTC), rather than being lost. The remaining, non-refundable portion of the credit can only offset taxes you actually owe.

To claim the refundable portion, you generally need at least $2,500 of earned income for the year; the refundable amount is calculated as 15% of earned income above that threshold, up to the $1,700-per-child cap. This is why the credit matters most for working families with modest tax bills, not just high earners looking to reduce a large liability.

Who Counts as a Qualifying Child

To claim the credit for a dependent, the child generally must meet all of the following at the end of the tax year:

• Be under age 17 at the end of the tax year
• Be your son, daughter, stepchild, foster child, sibling, or a descendant of any of them (like a grandchild or niece/nephew)
• Have lived with you for more than half the year
• Not have provided more than half of their own financial support
• Be claimed as a dependent on your return
• Not file a joint return for the year (unless only to claim a refund of withheld tax)
• Be a U.S. citizen, U.S. national, or U.S. resident alien, and have a valid Social Security number

That last requirement, a valid Social Security number issued before the due date of your return, is worth double-checking every year, especially in blended families or households where a child’s immigration or documentation status changed recently. A missing or invalid SSN disqualifies that child for the credit entirely, even if every other requirement is met.

Credit for Other Dependents

Dependents who don’t meet the Child Tax Credit’s age or relationship rules, such as a 17- or 18-year-old child, a dependent parent, or another qualifying relative, may still qualify for the separate $500 nonrefundable Credit for Other Dependents. It’s smaller and fully nonrefundable, but it prevents older kids and other dependents from falling through the cracks entirely once they age out of the main credit.

The Child Tax Credit works alongside other deductions, not instead of them; whether you take the standard deduction or itemize has no effect on your eligibility for this credit. If you’re self-employed and supporting dependents, it’s also worth checking whether you qualify for the home office deduction, since the two commonly apply to the same household in the same tax year.

Bottom Line

Most families claim the Child Tax Credit correctly without much thought, since tax software and preparers apply it automatically once dependents are entered. The two places people leave money on the table are forgetting to check ACTC eligibility when their tax bill is small, and failing to catch an SSN or residency issue for a dependent before filing.
