The Summer tax bill is sent out early July and is due September 30 without additional penalty or interest. Certain eligible seniors may qualify for a deferral of the due date to mid-February (check with the Treasurer's office for the exact date each year, because it is set annually by the State of Michigan). They may file an Application for Deferment of Summer Taxes, available from the Michigan Department of Treasury or the City Treasurer. Winter tax bills are sent out early December and due in mid-February (again, check for the exact date each year). The Treasurer’s office accepts payments 9 a.m. to 5 p.m., Monday through Friday except holidays. There is also a 24-hour secure drop box outside the Pine Street entrance to City Hall in which payments may be made.
