Establishes a caregiver tax credit, a tax credit for certain vulnerable persons, and the "Missouri Child Tax Credit Act"

HB 2643 establishes a refundable tax credit in Missouri for parents of children under the age of seventeen, providing $1,800 annually for children under six and $1,500 for older children. The bill allows eligible taxpayers to receive these funds as monthly advance payments starting in 2025, with a total annual cap of $10,000 or six credits per family. To qualify, a child must be claimed as a dependent on a federal tax return, live with the taxpayer for more than half the year, and not provide more than half of their own support. The legislation also authorizes the state Department of Revenue to proactively identify eligible taxpayers and adjust advance payments based on updated income information.
