Establishes the "Revitalizing Missouri Downtowns and Main Streets Act"

This bill creates a tax incentive program to encourage the conversion of older office buildings into residential or commercial spaces in Missouri. It directly affects property owners and developers who wish to repurpose existing office buildings that are at least 25 years old into apartments, retail, or other commercial uses. The program provides state tax credits equal to 25% of conversion costs for standard projects, or 30% for upper-floor housing in designated main street districts, with a total annual cap of $50 million. Tax credits can be sold or transferred to other taxpayers, and applications are reviewed by the Missouri Department of Economic Development based on submitted project plans and documentation.
