HB 4951 Michigan House · 2025-2026 Regular Session

Marihuana: taxation; comprehensive road funding act; create. Creates new act. TIE BAR WITH: HB 4183'25, HB 4961'25, HB 4968'25

HB 4951 creates a new tax on marijuana sales to fund state road infrastructure projects. It directly affects marijuana businesses (which pay the tax) and state transportation budgets (which receive the revenue). The key mechanism establishes a dedicated funding stream, redirecting tax revenue from cannabis sales toward repairing and maintaining roads, rather than general state funds. The bill became law immediately upon the Governor's approval on October 7, 2025.
