the michigan constitution and state statutes limit the amount of property tax millage that townships can levy for general township operations. general law townships are allocated at least 1 mill from the constitutionally limited 15/18 mills allocated among townships, the county, public schools and the intermediate school district. charter townships, like cities, do not share in this allocated millage, but townships chartered by a referendum may levy up to 5 mills. townships chartered by board resolution after nov. 22, 1978, must have a vote of the electors authorizing the levy of up to 5 mills. in either case, the 5-mill limit may be increased up to 10 mills with a vote of the electors.
