Bay City grew up where the Saginaw River meets Saginaw Bay, and its history is written along that waterfront. In the lumber boom of the late 1800s, the Saginaw Valley was the center of the country's logging trade, and dozens of sawmills once lined the river here — with dozens more upstream toward Saginaw. The timber and shipbuilding money built the grand Victorian homes of the Center Avenue Historic District, one of Michigan's best collections of 1800s mansions, and you can still tour a Navy destroyer, the USS Edson, docked on the river.

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 Bay City, your rate can vary by parcel. The school district tied to the property matters, and 2 school districts cover Bay City. For a primary home with PRE, Michigan's main-home exemption, rates currently run about 46.7 to 46.9 mills. Without PRE, non-homestead rates run about 64.7 to 64.9 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 Bay City
The river still splits the city into an east side and a west side, crossed by old bascule drawbridges that tilt up to let freighters and sailboats through. Two of the four bridges now charge a toll, so locals plan their routes around which crossing is open and free that year.
A few practical things shape buying here. Much of the city is low ground along the river and bay, so flood maps and shoreline risk are worth a look. The lower river and bay are also a designated cleanup area for dioxin from upstream, which means fish advisories and, for riverfront property, floodplain history worth asking about. And Michigan sends two property-tax bills a year. The notes below explain all three.
