Mobile Machinery

Mobile Machinery Defined
Mobile machinery is defined as heavy equipment, except shop or hand tools, which is self-propelled, towed, or hauled and used primarily in construction and maintenance of:

  • Roads
  • Bridges
  • Ditches
  • Buildings
  • Land reclamation

Wyoming contractors are required by State Statute to register mobile machinery or place it on the tax roll of the County in which it is being operated, as well as purchase a mobile machinery sticker.

Owned and leased mobile machinery must meet one of the following requirements before it is operated in the State of Wyoming and before the required mobile machinery sticker  is purchased through the Treasurer's Office:

  • Registered at full value with the County Treasurer's Office


  • Listed on the property tax assessment roll with the County Assessor's Office

You can contact the Treasurer's Office at (307) 733-4770 to find out the different sticker options available (daily, monthly, or yearly) and then decide which option is best for you. Whether you choose to register a piece of mobile machinery at full value with the Treasurer or list it as business personal property, you need to complete the Application for Mobile Machinery Registration and state the:

  • Type of machinery
  • Make
  • Model
  • Vehicle Identification Number
  • Acquisition year
  • Cost including sales tax and installment cost
It is necessary to replace this sticker every year by January 1 or immediately purchase a new sticker for machinery acquired after January 1. All mobile machinery acquired after January 1 of the tax year is prorated for the number of months it is owned or leased in that year, then it is put on the next full tax year.
