Overview
The state transportation budget supports state and local highway programs, public transportation programs, aeronautics
programs, and administration of the Michigan Department of Transportation (MDOT). Historically, two-thirds of the
revenue in this budget has come from state restricted revenue, with approximately one-third from federal sources. State-
restricted revenue in this budget includes revenue from motor fuel taxes, vehicle registration taxes, and from a $600.0
million earmark of Income Tax Act revenue. Approximately $3.7 billion in state restricted revenue is first credited to the
Michigan Transportation Fund (MTF) and then distributed in accordance with 1951 PA 51 ("Act 51") to other state
transportation funds and programs, including the State Trunkline Fund (STF), the Comprehensive Transportation Fund
(CTF), and local road agencies (county road commissions and cities/villages). Revenue from aviation fuel and registration
taxes, as well as a portion of Airport Parking Tax revenue, is credited to the State Aeronautics Fund for aeronautics
programs. Federal funds for transportation programs are authorized under the federal Infrastructure Investment and Jobs
Act (IIJA).
