Ontonagon Township sits where the Ontonagon River meets Lake Superior, and it's the most populated part of Ontonagon County. The name is Ojibwe and belonged to the river first; the great Ontonagon Boulder — a 3,708-pound mass of nearly pure copper, sacred to the Ojibwe and known to French voyageurs by the 1600s — once sat along that river before it ended up in the Smithsonian. The township wraps around the village of Ontonagon, the old harbor town at the river's mouth.

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 Ontonagon Township, your rate can vary by parcel. The school district tied to the property matters, and 2 school districts cover Ontonagon Township. For a primary home with PRE, Michigan's main-home exemption, rates currently run about 30.8 to 45.8 mills. Without PRE, non-homestead rates run about 48.8 to 63.8 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. Out here, a home beyond city water and sewer usually comes with a private well and septic system worth testing before you close. 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.
