Requirements to license a vehicle: Wyoming Title - proof of insurance on motorized vehicles - proof that the vehicle was registered in another state to you or proof that you paid sales tax.  If this is a new purchase, you will be charged sales tax based on the rate in effect in your Wyoming place of residence.  Sales tax must be paid within 50 days of purchase or be subject to penalty and interest on the tax amount. 

Motor Vehicle county fees are based on the original value (factory price) of the vehicle from the factory to the dealer plus all options.  This gives the valuation which is then multiplied by 3% which gives the county fee.  This fee is in lieu of property tax and can be deducted from federal income tax if you file the long form.  The state fee is a flat fee of $15.00 for cars and campers.  Trucks, trailers and motor home`s state fee is based on weight.

Example: 08 Car factory price $35,000.00 x 60% = $21,000 x 3% = County fee $630.00. This fee is pro-rated downward for the first 6 years of the life of the vehicle till the formula would be $35,000.00 x 15% = $5250.00 x 3 % County fee $157.50.  The % is as follows: 60% - 50% - 40% - 30% - 20% - 15%

There is a calculator for estimating your cost on the Wyoming County Treasurer`s Association site

As you can see the more expensive your vehicle the more it costs to license in Wyoming.  Wyoming is not cheap when it comes to motor vehicle fees.  Please contact us for more information if you plan to move to our state.  

You are required to license immediately upon employment, even if you are self-employed, or you have 120 days if not employed or retired as long as you are currently registered in another state.
