An Act establishing a child and family tax credit

This bill establishes a new tax credit in Massachusetts to provide financial relief to families with children or disabled dependents. It directly affects taxpayers who maintain households including at least one qualifying child, a qualifying individual under federal law, or a disabled dependent. The key provision allows eligible families to receive a credit of $600 for each qualifying member, with an annual adjustment mechanism to account for inflation. Additionally, the bill specifies that married couples must file jointly to claim the credit and ensures that any excess credit amount is refunded to the taxpayer without interest.
