What is Child Tax Credit?

The Child Tax Credit is a refundable credit for taxpayers who have one or more qualifying dependent children under age 18 at the end of the tax year. (Note: If filing separately or divorced, only the parent who claims the child as a dependent qualifies for this credit.)

For 2021 the credit is up to $3,600 per child under the age of 6 and $3,000 for each child under the age of 18.
