Establishes the "Missouri Entertainment Facility - Capital Assistance Program"

HB 1556 establishes Missouri's "MEF-CAP" program to provide state financial assistance for large-scale entertainment facilities like professional sports stadiums. It targets projects with at least $250 million in costs, 20,000+ seating capacity, and 33% private funding, requiring economic impact studies and a 25-year lease commitment from professional sports franchises (e.g., NFL, NBA teams). Assistance includes up to 50% of incremental state tax revenue, 50% withholding tax retention, or 25% matching grants, all subject to repayment if teams relocate or requirements aren't met. The program is administered by the Missouri Department of Economic Development with oversight from the Missouri Development Finance Board.
