HB 4184 increases Michigan's excise tax on aviation fuel from 3.10 cents to 4.00 cents per gallon. It directly affects fuel sellers, airlines, and airport operators by changing how this tax revenue is distributed. The bill modifies Section 203 of the Aeronautics Code to require 35% of the tax revenue to fund the state aeronautics fund and 65% to fund qualified airports. It also retains the 1.5-cent refund for airlines operating interstate flights and the exemption for fuel used in leaded racing fuel production.
