Property Taxes

Summer tax bills are payable July 1 to and including September 10 without penalty. After September 10 please add one percent interest for September plus one percent interest the first of each month thereafter. December tax bills are payable December 1 through the last day of February. Should September 10 or the last day of February fall on a weekend the last day to pay is the following Monday. We accept U. S. Postmarks as date of payment. After February please contact the Mackinac County Treasurer at (906) 643-7318 balances due as well as additional penalty and interest.

You may also look up taxes at the BS&A website. However, payments are not reflected on this site until the Mackinac County Treasurer updates them the following March.
