HB 4456 establishes a 30% excise tax on the wholesale cost of e-liquid sold in Oklahoma. Manufacturers, distributors, or retailers who first receive e-liquid in the state must pay this tax and remit it electronically by the 15th of each month. The tax is structured as a direct cost to consumers, though collected from businesses, and revenue is split: 50% to a new Vapor Products Regulation Revolving Fund and 50% to the General Revenue Fund until 2028, after which 75% goes to the General Fund and 25% to the revolving fund for future regulation. The bill directly affects businesses selling e-liquids and ensures tax collection through retained invoices and Commission oversight.
