2026 Summer/Fall Property Inspections:
Onsite property inspections are a normal function of the County Assessor's Office, and play a very important role in your property's valuation. If you have any questions regarding the validity of the inspection, please feel free to call our office at 307-733-4960 to confirm the identity of our appraisers. We are happy to answer your questions about the process.
Per Wyoming State Statute 18-3-205 (a): Any person interfering with the county assessor or deputy county assessor in the discharge of his duties, or any person refusing to allow the county assessor, deputy county assessor or representative of the department of revenue to examine any property pursuant to W.S. 39-13-103(b)(v), is guilty of a misdemeanor, and upon conviction shall be fined not more than seven hundred fifty dollars ($750.00), or imprisoned for not more than six (6) months in jail or both.
Placing Fair Market Value
The function of the Assessor`s Office is to place value on properties, which represents typical sale and/or purchase prices of similar properties. This procedure is known as placing fair market value on property. All property is assessed as of January 1 each year using sales occurring between January 1 and December 31 of the previous year. If a requisite number of sales have not occurred in the previous year, the assessor must extend the period of time from which sales are drawn.
Fair market value is the most probable price expressed in terms reasonably equivalent to cash that a property would bring if exposed for sale in the open market in an arm`s length transaction between a willing seller and a willing buyer, both of whom are knowledgeable concerning all the uses to which the property is adapted and for which it is capable of being used.
Value; Not Taxes
The Assessor`s Office is responsible for valuing all real and personal property in Teton County, but does not determine the amount of tax to be collected. Each year, the Board of County Commissioners analyze the budgetary needs of the county and set the mill levy. The mill levy is multiplied by your assessed value to determine the amount of property tax you may owe.
Statutory Duties
It is the statutory duty of the Assessor`s Office to locate, identify, and value all taxable property in Teton County. We are mandated and prescribed by state law on how we perform our assessments and when we perform our assessments.
Value of Transactions
The Assessor has not created the value of your property. People make value by their transactions in the marketplace. The Assessor simply has the legal responsibility to study those transactions and appraise your property accordingly. (View the International Association of Assessing Officers website for more details.)
Mission Statement
Our mission is to locate, identify, and value all taxable property in Teton County using state mandated methods, transparency, and service that assures public confidence in the accuracy and fairness of our valuations.
