     HOW TAXES ARE CALCULATED: 

    Actual Value x Assessment Rate = Assessed Value
    Assessed Value x Mill Levy = Taxes


    Example using a $300,000 residence and 100 mills levy: 
    $300,000 X 7.96% = $23,880 
    $23,880 X 0.100 = $2,388.00 total taxes 

    If the total mill levy is 100 mills and using the residential assessment rate of 7.96% and a non-residential assessment rate of 29%, annual taxes would be: 

    • For residential property - $7.96 per $1,000 of value. 
    • For non-residential property - $29 per $1,000 of value. 

     

    However, taxes for like-valued properties will vary based on the specific mill levy for the tax district where the property is located. Total mill levies range from 76.7920 mills to 196.6210 mills with an average of 105.428. and a median of 99.205. Thus, a home with a $300,000 actual value could be subject to property taxes ranging from $1,834 to $4,695 depending on the tax district in which it is located.
