This bill amends Michigan's Motor Fuel Tax Act to increase taxes on gasoline and diesel fuel, directly affecting drivers and fuel suppliers in the state. It establishes specific tax rates that rise from 19 cents per gallon for gasoline and 15 cents for diesel through 2016, to 26.3 cents per gallon through 2025, and then to 48 cents per gallon starting October 1, 2025. Additionally, the legislation introduces an annual inflation-based adjustment mechanism beginning in 2022, where future rates will increase by the lesser of 5% or the inflation rate, while also clarifying reporting requirements for fuel terminals and suppliers.
