Why the rate depends on the address
A Michigan property is taxed by every unit it sits in: the county, the township or city, the village if it's in one, the school district and intermediate school district, and sometimes a library, college or authority. Troy spans more than one combination of these, so this page shows each one.
Your tax bill, or your county's appraisal or assessment office, lists the units for your property.

- Rates across Troy's 7 areas differ by 11.6285 mills, so the address matters.
Medians are of the lowest combined rate in each place, across 62 places in Oakland County. Percent changes compare two published rates; a rate change isn't the same as a bill change, because values change too.
Estimate your 2025 bill
