Ithaca is Gratiot County's seat — the small, tidy town where county business gets done — and its centerpiece is one of the prettiest courthouses in mid-Michigan. The Gratiot County Courthouse, built of stone between 1900 and 1902 in a grand Classical Revival style with a tall clock tower, still stands at the heart of a historic downtown and still serves as the working courthouse. The settlement was first called Gratiot Center in the 1850s, then renamed Ithaca in 1857 after Ithaca, New York. Surrounded by farmland, the town keeps its agricultural roots alive with the yearly Ithaca Harvest Festival.

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 Ithaca, 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 42.8 mills. Without PRE, the non-homestead rate is about 60.8 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. 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.
