Oklahoma enacted S.B. 1339 which amends the definition of “marketplace facilitator” to include a person that facilitates not only retail sales of tangible personal property but all retail sales. S.B. 1339 also provides that the marketplace facilitator’s tax collection obligation applies to any other taxes administered by the Oklahoma Tax Commission which are levied by a local jurisdiction on the retail sale of a product. These changes are effective January 1, 2023.
