Sales tax: distribution; distribution of sales tax revenue for the revenue sharing trust fund; provide for. Amends sec. 25 of 1933 PA 167 (MCL 205.75). TIE BAR WITH: HB 4311'25

HB 4312 amends Michigan's sales tax distribution by directing 8.62% of the 4% general sales tax revenue to the Revenue Sharing Trust Fund starting October 1, 2025, with funds distributed to cities, villages, townships, and counties. It maintains existing allocations for aviation fuel tax (35% to the state aeronautics fund, 65% to qualified airport funds) and sets a minimum $9 million annual deposit from computer software sales tax into the Michigan Health Initiative Fund. The bill also clarifies adjustments for school aid fund revenue losses due to specific tax exemptions. These changes directly affect local governments, airports, and health programs through revised tax revenue streams.
