Out in the Straits of Mackinac sits one of the few places in America where you can't drive a car. Cars have been banned here since 1898, so people get around on foot, by bicycle, and by horse-drawn carriage — some six hundred horses work the island each summer, even hauling the freight and the trash. The Anishinaabe knew this high, rounded island long before any fort stood on it and called it Michilimackinac, the Great Turtle. The British built Fort Mackinac on the limestone bluffs in 1780, and after the fur trade faded the island reinvented itself as a grand summer resort, lined with gingerbread Victorian cottages and crowned by the Grand Hotel.

Where is the house?
Pick the county, city or township, and school district. We use the official 2025 tax rates published by Michigan Treasury.
Not sure of the school district? Check the property listing. It is usually under "Schools."
Need to double-check the exact parcel? Use the official state estimator at treas-secure.state.mi.us/ptestimator or call the local treasurer. Rates can change across city, township, village, and school district lines, so the exact parcel matters.
Why a buyer's property-tax bill can change after a sale
In Michigan, property tax isn't figured on what you paid — it's figured on the home's Taxable Value, with the local millage rates applied to that number. While one owner keeps the home, Proposal A caps how fast that Taxable Value can climb. When the home sells, the cap usually comes off — this is called uncapping — and the Taxable Value resets toward the State Equalized Value, or SEV, which tends to run about half of a home's market value.
That reset is the part that catches buyers: a longtime owner may have been paying on an old, capped number, so the year after you buy, yours can jump to the new one — and your first full-year bill can land well above what the seller was paying. In Mackinac Island, one school district appears in the rate data. Parcel-specific tax districts can still matter. For a primary home with PRE, Michigan's main-home exemption, the rate shown here is about 25.4 mills. Without PRE, the non-homestead rate is about 33.2 mills. The calculator above turns those local rates into your actual number.
If this will be your main home, make sure that PRE is filed with the local assessor — it can lift up to 18 school-operating mills off the bill. Rentals, vacation homes, and second homes stay on the higher non-homestead rate.
The tax reset is the big one, but it isn't the whole checklist. It's also worth checking whether the address sits in a floodplain, and whether you'll owe a city income tax where you live or work. The buying-a-home guide walks through the rest.

Stories & local context
Get to know Mackinac Island
Today only a few hundred people live here year-round, mostly in the village, while summer brings ferries full of visitors drawn to the fort, the cottages, the bike ride around the shore, and more fudge shops than you can count. Most of the island is preserved as state park. Anything you can't get on the island comes over by boat.
On the practical side, Michigan property taxes usually arrive in two bills a year — one in summer and one in winter — rather than one. The notes below have the details on island life and the history.
