Trowbridge Township is farm-and-river country in Allegan County, set along the Kalamazoo River just outside the county-seat town of Allegan, whose downtown is known for its restored 1886 iron bridge. The old paper-mill towns of Otsego and Plainwell lie a short drive to the southeast. One of Michigan's biggest pieces of public land, the roughly 50,000-acre Allegan State Game Area, sits nearby to the west, with paddling, hunting, camping, trails, and big fall flights of Canada geese.

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 Trowbridge Township, your rate can vary by parcel. The school district tied to the property matters, and 3 school districts cover Trowbridge Township. For a primary home with PRE, Michigan's main-home exemption, rates currently run about 30.7 to 35.2 mills. Without PRE, non-homestead rates run about 48.7 to 53.2 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. 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.

Stories & local context
Get to know Trowbridge Township
If you're buying near the river, the Kalamazoo carries a long cleanup story. Stretches of it are a federal Superfund site because of old PCB contamination from the paper industry, and there's a fish-eating advisory along the corridor. It's worth knowing about, though it doesn't affect every property.
A couple of practical notes round things out. Townships can add special assessments on top of regular property taxes for things like roads or drains, so it's worth asking what's on a given parcel. And as everywhere in Michigan, you'll get two tax bills a year, summer and winter. The notes below have the details.
