Child tax credits (CTC) are offered to eligible families with children under 17 years of age. The federal CTC varies in amount based on income and number of children and is partially refundable if the credit is higher than the taxes owed; the refundable portion is called the additional child tax credit. In 2018, the federal CTC for children under 17 is $2,000 and up to $1,400 can be received as a refund. It is limited to 15% of income above $2,500, so families that earn less than $2,500 are not eligible. There is also a nonrefundable $500 CTC available for other qualifying dependents. In 2018, an estimated 29 million children from low income working families will not receive the full value of the CTC1. Some state governments also offer CTCs. Similar to the federal CTC, state eligibility and refund amounts vary by income and number of children2. The CTC could be expanded by increasing the credit amount, making the credit fully refundable, decreasing or eliminating the earnings threshold, or creating a fully refundable supplement for families with young children.
Expected Beneficial Outcomes (Rated)
Evidence of Effectiveness
Expanding refundable tax credits for working families, such as the child tax credit (CTC), is a suggested strategy to reduce poverty3, 4, 5, 6, 7, particularly among young children from very poor families3, 8, and encourage work in low income families9, 10. However, additional evidence is needed to confirm effects and determine optimal tax benefit amounts.
Available evidence suggests that the CTC can help reduce and alleviate poverty in the families that receive it8, 11. When income eligibility was reduced from $11,500 to $3,000 in 2009, for example, over 70% of additional benefits went to families with incomes below $30,0007. Eliminating the earnings threshold entirely would increase benefits for the poorest families7, 12.
A 2018 report suggests restructuring the CTC to phase in with the first dollar earned, allowing the full amount to be refunded, and, for families with young children (under 6), phasing in the CTC at 50% rather than 15%. This proposal would increase benefits by around $12 billion per year; extending the full refund to all young children in low income families, regardless of parents’ earnings, would cost an additional $2 billion per year3.
A 2015 report projects that making the child tax credit fully refundable would reduce child poverty by 12% (1.3 million children), with the greatest benefit among black and white children, and families with no working adults. Making the credit fully refundable would cost approximately $12.4 billion5.
Impact on Disparities
The Tax Cuts and Jobs Act of 2018 doubled the maximum child tax credit (CTC) from $1,000 to $2,000 for children under 17 with $1,400 refundable and lowered the minimum eligible income to $2,500 from $3,000. It also created a non-refundable $500 CTC for other dependents, and increased the income at which the credit phases out from $75,000 ($110,000 if married) to $200,000 ($400,000 if married). These changes will expire after 2025 unless they are extended, reverting to pre-2018 levels. An estimated 91% of families with children could receive the CTC in 20181.
California, Colorado, Idaho, New York, North Carolina, and Oklahoma have state child tax credits; Colorado and New York’s credits are refundable2.
