Assessment Terminology

Public Education & Terminology

Property assessment and taxation is a complex subject. Knowing the terminology will help you understand the assessment process. The Uinta County Assessor's office is dedicated to educating the public about procedures and methods used to be in compliance with State of Wyoming statutes, rules and regulations.

Fair Market Value

is the amount of money a well-informed buyer would pay and a well-informed seller would accept for property that has been on the open market for a reasonable amount of time, assuming neither buyer nor seller is acting under pressure.

Assessed Value

is the taxable value of each property. This value is calculated by multiplying the fair market value by the level of assessment.

Level of Assessment

is the percentage of the fair market value that determines assessed value. The current level of assessment for industrial use properties is 11.5 percent; all other properties are at 9.5 percent. The level of assessment is set by the legislature and is subject to change.


literally, is one thousandth. For tax purposes: $1 of taxes for every $1,000 of assessed value.

Mill Levy

is the number of dollars in taxes that a property owner must pay for every $1,000 of assessed value. This amount is based on budget requests from various taxing entities.

Assessment Date

under Wyoming Statute is January 1 of each tax year. All properties are valued, assessed and taxed to the owner of record on this date.

Mass Appraisal

is the process of valuing a universe of properties as of a given date, utilizing standard methodology, employing common data, and allowing for statistical testing. The goal of mass appraisal is the same as fee appraisal: to develop a reasonable estimate of fair market value.

CAMA (Computer Assisted Mass Appraisal)

is a computer system developed by the State of Wyoming to perform three functions:
· Warehouse information collected by the assessor's office staff. Information such as ownership, location, size, use, physical characteristics, condition, and sales information must be continually updated.
· Calculate complex equations and cost and depreciation tables which automate standard appraisal methods to estimate fair market value.
· Quality control features such as reports generated using various parameters.

Real Property

is defined as land and improvements (buildings and structures) permanently fixed to the land.

Personal Property

includes material assets that are not fixed to the land: furniture, machinery or equipment, transportable homes.

Statement of Consideration

is a document, which provides sales information that must be used in addition to other information to determine current market value. The seller, buyer or agent completes the document at the time of a property transfer. Information is confidential and not public record. Property owners may review the sales information used to determine the value of their property. The SOC review period is only during the 30-day appeal period and the property owner may not further disclose the sales information to other persons or property owners. Sales information may be introduced to the County Board of Equalization during a formal appeal, but actions must be taken to prevent its indiscriminate disclosure.

Neighborhood Boundaries

are developed by the assessor based on physical, economical, governmental, or social factors. These neighborhood boundaries are used when sales studies are done. Neighborhood maps are available for review in the assessor's office.

Tax Districts

are the geographic area on which a taxing entity has the right to levy taxes. These entities include school districts, counties, cities, water or sewer districts, fire districts or other specially formed districts as designated by state statute.

Tax Base

is the total value of property against which the property tax is levied.

Property Tax Appraiser

is the designation given to those persons who have completed the education and training mandated by the State of Wyoming for anyone making a valuation judgment used as a basis for property taxation.
