Common questions
What is the property tax rate in Keego Harbor, Michigan?
Keego Harbor is taxed at 40.2912 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 $7,051 a year.
Does the tax rate change by address within Keego Harbor?
No. All of Keego Harbor sits in West Bloomfield School District, so the millage is 40.2912 at every address in the municipality. Your bill still changes after you buy, because it is recalculated on the uncapped taxable value rather than the seller's capped one.
How much are property taxes on a $350,000 home in Keego Harbor?
About $7,051 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 Keego Harbor 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 Keego Harbor compare with the rest of Oakland County?
It is the 40 lowest of 52 municipalities in Oakland County and 165 of 236 across the eight-county region — 5.91 mills above the county median.
