HB 4424 exempts qualifying manufacturing facilities and data centers from property taxes for five years. It directly affects businesses meeting specific criteria, including data centers operational by January 1, 2027, with at least 50% out-of-state revenue, and facilities investing $500,000+ (adjusted annually for inflation) in new or expanded operations. Key provisions require annual verification of eligibility with the Oklahoma Tax Commission, including wage standards tied to the Oklahoma Quality Jobs Program for facilities seeking exemption after 2022. The bill also defines qualifying facilities to include certain data centers, distribution centers meeting investment and employment thresholds, and custom manufacturing under specific industry codes.
