Property tax: exemptions; personal property constituting certain hydrogen fuel pumps; exempt. Amends secs. 27 & 34d of 1893 PA 206 (MCL 211.27 & 211.34d) & adds sec. 9q. TIE BAR WITH: HB 4112'25

HB 4111 exempts certain hydrogen fuel pumps from Michigan property taxes after December 31, 2025. It directly affects businesses installing qualifying hydrogen fueling infrastructure, such as stations filling vehicles with hydrogen. The bill defines a "qualified hydrogen fuel pump" as equipment meeting H35 (35 MPa) or H70 (70 MPa) pressure standards for dispensing hydrogen into motor vehicles. This exemption applies to the pumps themselves (classified as personal property), not the land or buildings they occupy, and is added to Michigan’s property tax law under Section 9q. The change aims to support development of hydrogen fueling infrastructure by reducing operational costs for businesses.
