Taxing Authorities

A Tax Authority is a government entity authorized by law to assess, levy and collect taxes. It provides services to property owners and has a distinct boundary. The local taxing authorities (county, school district, city, fire protection, and other special districts) set mill levies. The mill levy requested by each taxing authority is based on a projected budget and the property tax revenue required to adequately fund the services it provides to its taxpayers.

Mill Levy Report and Certification of Levies and Revenue

The levy reports present a list of the tax areas in Adams County. Each tax area represents a unique combination of taxing authorities in the County.
All real estate properties in one tax area are in the same overlapping tax authorities. While each tax authority sets its own mill levy, the sum of the individual authority levies within the tax area is used to calculate the property tax paid for property within the tax area. Each tax area consists of different combinations of tax authorities. Therefore, the mill levies for most, if not all areas, differ. The breakdowns in each tax area show the tax authorities and the levies within the area. The total levy for the authorities within an area equals the levy which is multiplied by assessed value to determine property taxes.
