Transportation: motor fuel tax; incentives for the sale and production of biodiesel; provide for. Amends 1967 PA 281 (MCL 206.1 - 206.847) by adding sec. 279.

HB 4722 creates tax credits to incentivize biodiesel use in Michigan. Retail fuel dealers selling biodiesel blends (6-9% at $0.02/gal, 10-19% at $0.05/gal, 20%+ at $0.07/gal) can claim credits, while biodiesel producers get $0.02 per gallon produced. Credits apply for tax years 2025-2030, with a $16 million total cap for retailers and a $2 million cap for producers. This directly affects Michigan fuel retailers and biodiesel manufacturers by reducing their income tax liability for qualifying sales and production.
