A bill for an act relating to fuel taxation by extending tax credits for E-85 and E-15 gasoline, and biodiesel, and extending sales tax refunds for biodiesel production.

HSB 237 extends several existing tax credits and sales tax refunds related to renewable fuels. It prolongs the availability of tax credits for retail dealers who sell E-85 gasoline, E-15 plus gasoline, and biodiesel blended fuel. Additionally, the bill extends sales tax refunds for companies that produce biodiesel. These provisions, previously set to expire between 2026 and 2028, are generally extended until December 31, 2030, or January 1, 2030. The bill also ensures these tax credits are available for an entire tax year for retail dealers whose tax year does not align with the repeal date.
