Modifies provisions related to county sales tax increases

This bill creates a state income tax credit for Missouri taxpayers who donate to nonprofit diaper banks. To qualify, donors must give at least $100 to a certified diaper bank, allowing them to claim a credit equal to 50% of their donation, up to a maximum of $50,000 per year. The state Department of Social Services is responsible for identifying eligible diaper banks and managing a system where the total annual tax credits available to all donors are capped at $500,000, which are then distributed among the qualifying organizations.
