Michigan Compiled Laws, Chapter 123. Local Government § 123.747

Sec. 17. A contract or assessment made under this act may provide that if a municipality shall fail to pay to a county operating under this act any amount required to be paid under any contract or assessment when due, then the county treasurer shall notify the state treasurer, or other appropriate disbursing official, who is hereby directed to deduct the amount from any moneys in his possession belonging to the municipality which are not pledged to the payment of debts, but the state treasurer or other official shall not withhold in any 1 year a sum greater than 25% of the total amount owed the county by the delinquent municipality as stated in the notice from the county treasurer. Nothing in this section shall permit the deduction of moneys in contravention of the constitution, but a municipality itself may authorize, in any contract with a county operating under this act, the deduction and transfer from moneys derived from unrestricted state funds returnable to the municipality. The right of deduction given by this act shall not operate to limit the county's right to pursue other legal remedies for the reimbursement of moneys paid by the county hereunder on behalf of a municipality other than the county and the county board of commissioners of a county which has paid any money on behalf of any other municipality and which was not reimbursed therefor, may order the municipality and its officers to levy upon its next tax roll an amount sufficient to make the reimbursement on or before the date when its taxes become delinquent; and the municipality and its tax levying and collecting officials shall levy and collect the taxes and reimburse the county.
