The Child Tax Credit (CTC) is a federal tax benefit designed to help eligible families with the cost of raising children. The CTC is worth up to $2,200 per qualifying child. For qualifying taxpayers, part of the credit may be refundable through the Additional Child Tax Credit (ACTC), meaning families may receive money back even if they do not owe enough federal income tax to use the full credit. Eligible families may qualify for up to $1,700 per qualifying child in refundable ACTC benefits, depending on their circumstances. Eligibility generally depends on factors such as the child’s age, relationship to the taxpayer, residency, Social Security number and family income.To qualify for the Additional Child Tax Credit (ACTC), you generally need at least $2,500 in earned income. You may be eligible for the full Child Tax Credit for each qualifying child if you meet all IRS requirements and your annual income is no more than $200,000, or $400,000 for married couples filing jointly.
