Child Tax Credit in 2026: Income Limits, Amounts, and Rules
The Child Tax Credit is one of the most significant tax benefits available to families with dependent children. For the 2026 filing season, which covers the 2025 tax year, the credit continues to provide meaningful tax relief for qualifying families, though the specific parameters, including credit amounts, income phase-outs, and refundability rules, depend on both baseline law and any legislative changes enacted in 2025. This guide explains how the credit works, who qualifies, and how to claim it correctly.[1][2]
What Is the Child Tax Credit?
The Child Tax Credit reduces your federal tax liability by a set dollar amount for each qualifying child under age 17. Unlike deductions, which reduce your taxable income, a credit directly reduces the amount of tax you owe. If the credit exceeds your tax liability, you may be eligible for a partial refund through the refundable portion of the credit, known as the Additional Child Tax Credit.[1][3]
2025 Credit Amount and Refundability
For the 2025 tax year, the Child Tax Credit is set at $2,000 per qualifying child under age 17. Up to $1,700 of this credit per child is refundable through the Additional Child Tax Credit for taxpayers whose credit exceeds their tax liability. This means that even if you owe little or no tax, you may still receive a partial refund based on qualifying child credit amounts.[1][2]
These amounts are based on current law and may have been adjusted by legislation enacted in 2025. Taxpayers should verify the applicable credit amount with updated tax software or IRS guidance.[2]
Income Phase-Out Thresholds
The Child Tax Credit begins to phase out when your adjusted gross income exceeds the following thresholds:[1][2]
$400,000 for married couples filing jointly
$200,000 for single filers, heads of household, and married filing separately
Above these thresholds, the credit is reduced by $50 for every $1,000 (or fraction thereof) of income above the limit. At high enough income levels, the credit is fully phased out.[1]
Who Is a Qualifying Child?
To claim the Child Tax Credit, your child must meet all of the following requirements:[1][2]
Age: Under age 17 at the end of the 2025 tax year, meaning born on or after January 1, 2009
Relationship: Must be your child, stepchild, foster child, sibling, step-sibling, or a descendant of any of these
Dependent: Must be claimed as a dependent on your return
Social Security number: Must have a valid SSN issued before the due date of your return
Residency: Must have lived with you for more than half of 2025
Support: Must not have provided more than half of their own financial support during the year
Citizenship: Must be a U.S. citizen, U.S. national, or U.S. resident alien
How to Claim the Credit
To claim the Child Tax Credit, enter your qualifying children's information on your Form 1040, including their names, Social Security numbers, and relationships. The credit is calculated on Schedule 8812, Credits for Qualifying Children and Other Dependents, which is automatically generated by tax software.[1][3]
If you share custody of a child and you and your co-parent both attempt to claim the child, the IRS tiebreaker rules determine who is entitled to the credit. Generally, the parent with whom the child lived the most during the year has the primary right to claim the credit.[2]
Additional Child Tax Credit: Getting a Refund
If your Child Tax Credit exceeds your total tax liability, you may be eligible for the Additional Child Tax Credit, which is the refundable portion. For 2025, the ACTC is calculated as 15 percent of your earned income above $2,500, up to the maximum refundable amount per child.[1][2]
Returns claiming the ACTC are subject to an IRS processing hold under the Protecting Americans from Tax Hikes Act. The IRS cannot issue ACTC refunds before mid-February, even if the return was filed in January. Plan your financial expectations accordingly if you anticipate an ACTC refund.[2]
Other Dependent Credit
For dependents who do not qualify for the Child Tax Credit, such as college-age children or elderly parents you claim as dependents, a separate Credit for Other Dependents of $500 is available. This credit is not refundable, but it reduces your tax liability for qualifying dependents who do not meet the age or SSN requirements for the full Child Tax Credit.[1][3]
Conclusion
The Child Tax Credit remains a cornerstone of tax relief for families with children. Confirming that your children meet all qualifying requirements, understanding the income limits that may reduce your credit, and ensuring your return accurately reports all dependent information are the key steps to claiming the full credit you are entitled to in the 2026 filing season.[1][2][3]
