Town Property Tax
Property tax assessments
Local governments levy property taxes on all privately owned real property regardless of use. The amount of tax levied is based on the assessed valuation of the property and the Town’s mill levy. The tax is assessed by multiplying the assessed valuation by the mill levy rate. The Douglas County Assessor’s Office establishes valuation. To look up your property’s assessed value, visit the County Assessor’s parcel search.
