How to claim Additional Child Tax Credit 2026 and check eligibility for ACTC refund

As tax season approaches, many US families are evaluating how much they may receive through the Additional Child Tax Credit (ACTC) in 2026. The credit remains one of the most significant tax benefits available to parents and guardians, particularly those with low or moderate incomes.

What is the Child Tax Credit and ACTC?

The Child Tax Credit (CTC) is designed to provide financial relief to taxpayers with qualifying children. It can reduce the amount of federal income tax owed.

There are three related categories:

• Child Tax Credit (CTC): A nonrefundable credit that reduces tax liability for eligible taxpayers with qualifying children.
• Additional Child Tax Credit (ACTC): The refundable portion of the CTC. If the credit exceeds the tax owed, eligible taxpayers may receive part of it as a refund.
• Credit for Other Dependents (ODC): A nonrefundable credit for dependents who do not qualify for the CTC or ACTC.

For 2026, eligible taxpayers may claim up to $2,200 per qualifying child under the Child Tax Credit. If their tax liability is low or zero, they may qualify for up to $1,700 per child as a refundable amount under the ACTC, depending on income.

Who is eligible for the Additional Child Tax Credit in 2026?

• To qualify, the child must meet specific criteria:
• Be under 17 years old at the end of the tax year
• Not provide more than half of their own financial support
• Have lived with the taxpayer for more than half the year
• Be claimed as a dependent on the taxpayer’s return
• Be a US citizen, US national, or US resident alien

Eligibility for the refundable portion also depends on earned income and overall tax liability.

How to claim the ACTC refund

Taxpayers must file Form 1040 (U.S. Individual Income Tax Return) and complete Schedule 8812 (Credits for Qualifying Children and Other Dependents) to calculate and claim the credit.

Families must list the names and details of qualifying children and dependents on the return. Even taxpayers who typically do not owe taxes may need to file in order to receive the refundable portion.

When will ACTC refunds be issued?

Under IRS processing rules, refunds that include the Additional Child Tax Credit cannot be issued before mid-February. This delay applies to the entire refund amount, even if part of it is unrelated to the ACTC.

Taxpayers can check their refund status using the IRS “Where’s My Refund?” tool beginning in mid-to-late February.

Why the ACTC matters in 2026

With ongoing federal tax adjustments and legislative changes, the Additional Child Tax Credit continues to play a major role in supporting working families. Understanding eligibility rules and filing requirements can help ensure taxpayers receive the full benefit for which they qualify.
