Michigan Compiled Laws, Chapter 45. Counties § 45.595

Sec. 15.  (1) A contract made under this act may provide that if a public corporation fails to pay to a county an amount required to be paid under the contract when due, then the county treasurer shall notify the state treasurer, or other appropriate disbursing official, who shall deduct the amount from money in the treasurer's possession belonging to the public corporation that is not pledged to the payment of debts.  Upon the giving of notice in writing to the state treasurer, a public corporation itself may authorize, in a contract with a county, the deduction and transfer of money derived from unrestricted state funds returnable to the public corporation.

(2) The right of deduction given by this act does not limit the county's right to pursue other legal remedies for the reimbursement of money paid by the county under this act on behalf of a public corporation other than the county.  The county board of commissioners of a county that pays money on behalf of a public corporation under this act and that is not reimbursed for the payment may order the public corporation 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.  The public corporation and its tax levying and collecting officials shall levy and collect the taxes that are ordered and reimburse the county.
