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. Watertown Township 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.

Estimate your 2025 bill

Use the taxable value on your assessment notice or bill, not the assessed or market value. Taxable value is at most about half of market value.
