Full refundability entails removing the earnings limit and dollar limit on the refundable portion of the federal Child Tax Credit. In the absence of full refundability, children with parents or guardians who have less than $2,500 in earnings are ineligible for the federal CTC. Families above this earnings requirement receive a federal CTC worth 15 percent of each dollar of earnings over $2,500 until reaching a maximum credit of $2,000 per child. The CTC is also only partially refundable, so families can only receive $1,400 per child in the form of a tax refund. This means that families with a CTC that exceeds their tax liability can only receive $1,400 per child in the form of a tax refund.
