Bill No. 820 amends the Oklahoma Major Sports Leagues Rebate Program Act to expand the list of eligible professional sports leagues for rebate payments. The bill replaces the previous reference to the "five major sports leagues" with a broader definition that now includes the Women's National Basketball Association (WNBA), Women's Professional Fastpitch (WPF), and the National Women's Soccer League (NWSL). This change allows establishments classified under NAICS code 711211, which includes professional sports teams from these leagues, to qualify for quarterly rebate payments from the Oklahoma Tax Commission, provided they meet specific payroll and employment criteria.

Additionally, the bill outlines the application process for establishments seeking rebates, requiring them to demonstrate a projected annual gross payroll of at least $10 million and maintain a certain number of full-time-equivalent employees. It also stipulates that rebate payments cannot exceed $10 million in any single year and establishes a special fund within the State Treasury for managing these payments. The act is set to take effect on November 1, 2025.
