A bill advancing in the Legislature would exempt Michigan’s 275 Masonic lodges from property taxes. Supporters of the legislation , which won Senate approval Wednesday, say funding has become an issue for the fraternal service associations because Masons don’t have many options to increase revenue. Michigan law already provides tax exemptions for property owned by nonprofit charitable institutions, but they have been inconsistently allowed for Masonic associations. The nonpartisan Senate Fiscal Agency says 30 of the 275 lodges aren’t taxed today. Tax revenue would decline by between $600,000 and $2.3 million annually if the bill becomes law. It was passed 31-6 by the Senate and goes to the House for consideration. Three Republicans and three Democrats opposed the measure Wednesday.
