Non-Principal or Business Property Tax Calculator

For all properties that are not exempt from the 18 mills of school operating millage, (non-principal residence properties, commercial and industrial parcels) you may calculate an estimate of annual property taxes here. Enter a purchase price or an opinion of value and identify which school district the property is located in for a rough estimate of winter and summer taxes.
