Mill levies are used to determine how much each taxing entity receives. Once the taxable valuation has been calculated, it is multiplied by the mill levy to determine the amount of taxes due.
The number of mills in a tax district depends on how many mills each taxing entity requests. Wyoming state law limits most entities on how many mills they can levy. For example, the county can request a maximum of 12 mills, cities and towns get 8 mills to run their governments, and school districts are limited to 12 mills. With around 17 taxing entities in the county, it's easy to see how the mill levy can grow. As the mill levy grows, so does your tax bill.
Mill levies vary depending on what tax district the property is in. For example, rural tax districts have levies for rural fire protection and districts in the city limits have levies for running the city government.
