The federal child tax credit remains worth up to $2,200 per qualifying child for the 2026 tax year, with as much as $1,700 of that refundable to families who owe little or no federal income tax. The figure holds steady from 2025, the first year under the tax law that raised the credit from its prior $2,000 ceiling and indexed future increases to inflation. But the same law also tightened who can claim it, adding Social Security number requirements that strip eligibility from some mixed-status households even when a child qualifies on every other count.
How the $2,200 Credit Is Calculated
The Child Tax Credit lets eligible parents and guardians reduce their federal tax liability by up to $2,200 for each qualifying child under age 17, the IRS says. The full amount is available to single filers, heads of household and married-filing-separately taxpayers earning up to $200,000 in modified adjusted gross income, and to joint filers earning up to $400,000. Above those thresholds, the credit does not disappear all at once; it shrinks gradually as income climbs, a design meant to concentrate the benefit on working and middle-income households rather than the highest earners.
That phase-out moves at a fixed pace: the credit is reduced by $50 for every $1,000 of income above the applicable threshold, according to Kiplinger. A family with modified adjusted gross income of $220,000 filing jointly, for instance, sits comfortably below the $400,000 mark and keeps the full $2,200 per child, while a single parent earning $230,000 has already crossed $30,000 past the $200,000 line and lost roughly $1,500 of the credit’s value before other adjustments. The math rewards households near the middle of the income range and phases out entirely once earnings climb far enough past the threshold.
To count as a qualifying child, a dependent must be under 17 at the end of the tax year, be related to the filer as a son, daughter, stepchild, foster child, sibling or a descendant of one of those relationships, and have lived with the taxpayer for more than half the year, according to the IRS. The child cannot have provided more than half of their own financial support, must be claimed as a dependent on the return, and must be a U.S. citizen, U.S. national or resident alien. Every qualifying child, along with the parent claiming them, now needs a Social Security number valid for employment, a requirement examined further below.

The Refundable Additional Child Tax Credit
Because the base credit only offsets taxes actually owed, families with little or no tax liability can lose much of its value unless they claim the Additional Child Tax Credit, the refundable piece worth up to $1,700 per child. To qualify, a household must have at least $2,500 in earned income for the year; the ACTC then phases in at a rate of 15 cents for every dollar earned above that floor until it reaches the full refundable amount. The mechanism is designed to reach working families whose income is too low to owe substantial federal tax, not households with no earnings at all.
Claiming the refundable portion also changes the refund timeline. Federal law bars the IRS from issuing any refund tied to the Additional Child Tax Credit or the Earned Income Tax Credit before mid-February, and that hold applies to a taxpayer’s entire refund, not just the share connected to those two credits, the agency says. Filers who claim either credit are told to check the Where’s My Refund tool in mid-to-late February rather than expect the faster turnaround that a return without those credits typically gets.
Both figures are now indexed to inflation going forward, a change from the credit’s prior structure, but the refundable $1,700 cap did not move between the 2025 and 2026 tax years. The nonrefundable $2,200 maximum is indexed as well under the same law, meaning both numbers are positioned to rise in small increments in future years even though neither changed for the return households will file in early 2027.
New Social Security Number Rules Narrow Who Can Claim It
The 2025 tax law did more than raise the credit amount; it also added identification requirements that did not exist before. A qualifying child must now have a Social Security number valid for employment and issued by the return’s due date, and an Individual Taxpayer Identification Number is no longer sufficient to unlock the credit on the child’s behalf. The taxpayer claiming the credit, and that taxpayer’s spouse if filing jointly, must also hold a valid Social Security number of their own.
The effect falls hardest on mixed-status households. If a parent files using an Individual Taxpayer Identification Number rather than a Social Security number, the family is generally shut out of the credit even when the child holds a valid Social Security number. On a joint return, at least one spouse must carry a valid number for the household to qualify at all, which means the new rule can disqualify a family that met every other test under the credit for years before the 2025 law took effect.
Families who clear both the income and identification tests claim the credit by listing each qualifying child and dependent on Form 1040 and attaching a completed Schedule 8812, which walks filers through calculating the nonrefundable Child Tax Credit, the Credit for Other Dependents and the refundable Additional Child Tax Credit in a single form. Tax software generally runs through the schedule’s line items automatically once a filer enters dependent information, and paid preparers handle the calculation directly, but the underlying eligibility tests do not change based on who fills out the paperwork.
That gap between eligibility on paper and eligibility under the new identification rules is likely to widen the credit’s reach in some households and narrow it in others simultaneously: the dollar amount is larger and now inflation-protected, yet a family that has claimed the credit every year since 2018 could find itself excluded for the first time in 2026 solely because a parent’s tax filing number never converted to a Social Security number, regardless of how long that parent has worked and paid taxes in the United States.
