Mill levies are set by the taxing authorities in which your property is located. The property tax revenues support the schools, fire protection, roads, special districts and other local services in your specific area. The assessor reports the total assessed value to the taxing authorities in December each year so an accurate mill levy can be set. A property located in a tax area is taxed by that area's total net mill levy.
Mill levies are finalized at the end of December each year and posted early January. Mill Levies by Tax Area/District Report
