Wyoming Tax FAQ

What is Wyoming’s tax structure?

Wyoming has some of the lowest taxes in the nation.  To see rates and revenues collected for sales and use, property, severance, lodging, alcohol, tobacco, business licensing and estate taxes, see our Tax Revenue Quick Reference

In Wyoming, minerals play a major role in bringing in revenues to state and local government, in fact, it is estimated that minerals indirectly contribute up to 80% of the State’s revenue.  See WTA’s Minerals Contribution to Wyoming’s Revenue – October 2009.

How is property valued in Wyoming?

Because Wyoming does not impose an income tax, local governments largely rely on property tax collections.  In fact, in 2007, the State collected just over $1.37 billion in property taxes on a state-wide assessed value of $21.5 billion.  Almost 68% of these revenues come from minerals production and the majority of the revenues from property taxes are directed to Wyoming's public schools.

Property is valued as it exists on January 1st of each year. Assessed values should go out no later than the 4th Monday in May and the County Treasurer’s Office sends bills in September. Bills may be paid 50% due by November 10th and 50% due the next May 10th.

Wyoming assess property for tax purposes as follows:

  • Mineral production: 100% of fair market value;
  • Industrial property – utilities, pipelines, railroads and manufacturing; 11.5% of fair market value;
  • Residential real property, and commercial real and personal property: 9.5% of fair market value;
  • Agricultural Lands; 9.5% of productivity value
