Modifies provisions relating to taxation

SB 3 creates a new tax credit program in Missouri to attract sporting events by allowing taxpayers to receive credits against state income or franchise taxes for donations made to certified sponsors. Eligible donors include businesses, individuals, and organizations that contribute cash, stocks, or real estate to nonprofit groups (like local committees or certified sponsors) working to host events. The program requires applicants to submit documentation of event costs and donations, with credits tied to verified ticket sales or participant numbers for events hosted by organizations like the NCAA or USOPC. This directly affects donors seeking tax benefits and local entities bidding to host sports events, while excluding facility construction costs from eligible expenses.
