    Wyoming Statute - Title 39: Taxation & Revenue

    Department of Revenue Rules & Regulations: Chapert 9 - Ad Valorem Valuation (Local Assessment)

    Sublette County Commissioners' 2007-2008 State of the County Report
    Wyoming State Statutes give the County Assessor the responsibility of identifying, valuing and assessing all business personal property in Sublette County as of January 1 of each year. Businesses are identified through various means such as newly issued sales tax permit lists provided by the Department of Revenue, telephone books, advertisements, observations or word of mouth, and field inspections.

    Personal property, by definition, consists of every kind of property that is not real property. It is moveable without damage to itself or the real estate. Personal property for taxation purposes is any equipment, machinery, computers, tools, furniture, etc. used for business purposes. Licensed vehicles are not included.

    Proper reporting of business personal property is a responsibility and part of doing business in Wyoming. Personal property reporting has always been done on an honor system in this county. For the system to be fair, all businesses must honestly complete the personal property forms. All reports are subject to on-site review or audit for accuracy of reporting

    All property owners subject to taxation are notified in April of each year with the mailing of Assessment Schedules. Personal Property Assessment Schedules have the estimated market value and assessed value of the property reported by the business. Personal Property assessed value is a factor of the estimated market value minus depreciation. As with all assessments, they must be appealed within 30 days of the postmark date if the business objects to the value. (The Appeal Process is explained on the Real Property page.)

    If a business does not file a listing of personal property by the March 1 due date, a Non-Report Estimate of Value will be placed on the property based on the best available information and a fine may be imposed. The reporting deadline may be extended to April 1 if the Assessor’s Office is notified. According to Wyoming State Statute 39-13-108 (c), a business could be fined $500 with an additional $100 per day for failure to file or report accurately.

    After the first year of reporting, our office generates and mails a personal property listing reflecting the information provided the previous year. Each business must verify what is listed, check for accuracy, make corrections, deletions and/or additions, sign the form, and return it to our office by the March 1 due date.

    A commercial or agricultural company reporting $10,000 in Sublette County would pay on average $57.83 Personal Property Tax.

    Aircraft
    The Assessor’s Office receives a yearly list from the Wyoming Department of Revenue of registered aircraft in Sublette County. If you own an aircraft which is used solely for personal use, you must complete Form ATD23, Aircraft Affidavit Requesting Exemption from Property Tax, every year to affirm that the aircraft is used solely for personal use. For more information, click here for an explanation.

    Mobile Machinery
    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, or land reclamation.

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

    Before being operated in the State of Wyoming and before
    purchasing the required mobile machinery sticker through the Treasurer’s Office, mobile machinery owned or leased must be either
    • registered at full value with the County Treasurer's office or
    • listed on the property tax assessment roll with the County Assessor’s Office
    You can contact the Treasurer’s office at 307-367-4373 to find out the different sticker options available (daily, monthly or yearly) and then decide which option you would like to choose. 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 state what type of machinery, make, model, VIN#, acquisition year and cost including sales tax and installment cost if applicable by completing the Treasurer’s Application for Mobile Machinery Registration.

    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 and then it is put on for the next full tax year.
