Common questions

What is the property tax rate in Brockway Township, Michigan?

Brockway Township is taxed at 28.6411–29.7357 mills for a homestead (principal residence) under the official 2025 Michigan Department of Treasury millage report. On a $350,000 home at the uncapped taxable value that is about $5,012 a year.

Does the tax rate change by address within Brockway Township?

Yes. Brockway Township spans 2 school districts and the rate runs from 28.6411 to 29.7357 mills depending on the district your address falls in — a difference of $192 a year on a $350,000 home. The district table above lists every rate.

How much are property taxes on a $350,000 home in Brockway Township?

About $5,012 a year at the homestead rate. Michigan taxes the taxable value, not the sale price, and after a sale that value uncaps to roughly half what you paid — so $350,000 is taxed on about $175,000.

Why is the tax bill on a Brockway Township listing lower than what I would pay?

Because the figure on the listing is the seller's. Michigan caps annual taxable-value growth while an owner keeps the property, and that cap is removed the year after it sells. The longer the seller owned it, the further their bill sits below yours.

How does Brockway Township compare with the rest of St. Clair County?

It is the 22 lowest of 31 municipalities in St. Clair County and 89 of 236 across the eight-county region — 1.58 mills above the county median.

Why this matters: the increase hits in the tax year after your closing — so your first year looks fine and year two jumps. Lenders often escrow off the seller's old bill, which creates a shortage and a payment increase you didn't plan for.
