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 removes references to the "five major sports leagues" and replaces them with a broader definition that includes the Women's National Basketball Association (WNBA), Women's Professional Fastpitch (WPF), and the National Women's Soccer League (NWSL), in addition to the previously included leagues: the National Football League (NFL), National Basketball Association (NBA), National Hockey League (NHL), Major League Baseball (MLB), and Major League Soccer (MLS). This change allows more professional sports teams to qualify for quarterly rebate payments from the Oklahoma Tax Commission based on their gross payroll for sports-league jobs.

Additionally, the bill outlines the eligibility criteria for establishments seeking rebates, including a requirement for an annual gross payroll of at least $10 million and a minimum number of full-time-equivalent employees. It also establishes a special fund within the State Treasury for the rebate payments, which will be funded by a portion of taxes collected. The act is set to take effect on November 1, 2025.
