The Child Tax Credit is a financial benefit provided by the U.S. government to help families with children. It allows eligible parents or guardians to receive a credit on their federal income tax return, which can reduce the amount of tax owed or increase their refund. The credit is designed to support families in covering the costs of raising children. Eligibility for the Child Tax Credit typically depends on the family's income and the number of qualifying children under the age of 17. The amount of the credit can vary, and it may be fully refundable for some families, meaning they can receive the credit even if they do not owe taxes.
