The purpose of this legislation is to improve the Child and Dependent Care Tax Credit, making it more beneficial for families who incur costs for child care or care for dependents. The main objectives are to increase the amount of the credit, make it fully refundable for certain taxpayers, and adjust the income thresholds for eligibility. Key provisions of the legislation include significant increases in the dollar limits for the credit. The maximum amount that can be claimed for one child will rise from $3,000 to $8,000, and for two or more children, it will increase from $6,000 to 6,000.
