Wyoming has a 3 step process, starting at the State level.

The state sets the percentage to determine assessed value. For residential and commercial, that rate is somewhere around 9.5%. Industrial is a bit higher, around 11.5%. Agriculture is a bit different, it’s based on production.

OK – so let’s start a scenario. A home in Jackson Hole. In order to determine assessed value, we need to know Market Value, provided by local government. Let’s say Teton County sets the Market Value of this home at 900k. Now we can take the state percentage to determine assessed value. In this case, 900k X 9.5% is $85,500, assessed value.

Now let’s move to the tax rate set by the county. In Teton County it’s set in mills, (the mill levy). If that levy is around 86.5 mills (a mill is 1/1000, or 1/1000 of $1) we can take our assessed value, and multiply it by the mill levy. Again, the mill levy is just the “tax rate”. So, 85,500 x .0865 = 7395.75 in ANNUAL property taxes.
