SB 559 creates a new Revenue Sharing Trust Fund in Michigan's Department of Treasury, effective October 1, 2025. The fund will receive money from the general sales tax, donations, and investment earnings, with balances carrying over annually instead of lapsing. It mandates specific distributions: $299 million to cities, villages, and townships (based on prior eligibility regardless of new criteria), $261 million to counties (similarly based on prior eligibility), and remaining funds distributed through three formulas measuring taxable value, population type, and yield equalization. This directly affects all local governments in Michigan by changing how they receive state revenue-sharing payments.
