This bill, titled the "Child Care for American Families Act," aims to significantly enhance the existing employer-provided child care tax credit under Section 45F of the Internal Revenue Code. It increases the general credit percentage from 25 percent to 40 percent , with higher rates of 50 percent for eligible small businesses and 60 percent for facilities located in designated eligible areas, such as low-income census tracts or rural counties. The bill also substantially raises the maximum credit amount from $150,000 to $1,200,000 and the aggregate qualified expenditure limit from $500,000 to $2,000,000, making the credit more impactful for employers. To support the implementation of these changes, the bill directs the Secretary of the Treasury to issue necessary guidance , specifically addressing the application of the credit to multi-employer facilities . Furthermore, it mandates the establishment of a public awareness program within one year to inform eligible taxpayers about the credit and its filing procedures. Finally, the legislation requires the Comptroller General to conduct a GAO study within 12 months, examining state and local regulatory barriers affecting child care facilities and providing recommendations to reduce these burdens and enhance employer participation in providing child care.
