The American Family Act aims to enhance financial support for families with children by introducing a new refundable child tax credit that provides monthly advance payments. This initiative is designed to ease financial burdens and improve the management of family finances, particularly for those with lower to moderate incomes. Under the act, families will receive $300 per month for each child aged 6 and older, and $720 for each child under 6. The credit is refundable, meaning families can benefit even if they do not owe taxes, although the amount decreases for higher-income families.
