Introduction to Wyoming Taxation


What Are Property Taxes?

A property tax in Wyoming is an ad valorem tax. Therefore, the more your property is worth, the higher your taxes are.

In order to tax the property, a taxable value must be determined. First, the County Assessor assigns the property a fair market value. Next, the fair market value is multiplied by a taxation rate to calculate the taxable value. The taxation rate depends on how the Assessor classifies the property.
  • Formula:
    Fair Market Value
    x Taxation Rate
    Taxable Value


Properties are classified in one of three areas:
  • Gross production of minerals and mine products (taxed at 100%)
  • Property used for industrial purposes (taxed at 11.5%)
  • All other property, real and personal (taxed at 9.5%)
