Biodiesel Tax Credit Extension Act of 2025

HR 3137 extends federal tax credits for biodiesel production and use through 2026, directly affecting biodiesel producers, refiners, and businesses that purchase or use biodiesel. The bill updates tax code provisions to keep the biodiesel credit active until 2026 (instead of expiring in 2024) and prevents double benefits by disallowing credits for fuel already covered under a separate clean fuel production credit. It also extends related credits for second-generation biofuels until 2027 and applies to fuels sold or used after December 31, 2024. The changes maintain existing tax incentives without altering eligibility or creating new requirements.
