Wyoming Statutes
Wyoming Constitution Article 15, Section 11. “(a) All property, except as in this constitution otherwise provided, shall be uniformly valued at its full value as defined by the legislature, in three (3) classes”
- Wyoming Statute 39-13-103. “(b)(i) Except as otherwise provided: (A) All taxable property shall be annually listed, valued and assessed for taxation in the county in which located and in the name of the owner of the property on January 1.
- Wyoming Statute39-13-103. “(b)(ii) Property valued at fair market value. All property shall be annually valued at its fair market value. Except as otherwise provided by law for specific property, the department (Department of Revenue) shall prescribe by rule and regulation the appraisal methods and systems for determining market value using generally accepted appraisal standards.”
- Wyoming Statute 34-1-142 thru 144 require the filing of a Statement of Consideration (SOC) as part of each property transfer. These forms contain sales information. The statute also states that an individual SOC cannot be used to adjust the assessment on a property.
Wyoming’s Valuation System
Wyoming utilizes a Computer Assisted Mass Appraisal (CAMA) system to calculate property values statewide. The system combines technical data with market insights to ensure uniformity and fairness.
How the CAMA System Works
- Data Collection: Appraisers gather property details — such as structure, size, materials — and enter them into the CAMA database.
- Cost Assessment: Characteristics are priced using manuals from Marshall & Swift, which collects cost data from global and local sources.
- Valuation Calculation:
- Replacement Cost New (RCN) is the starting point.
- Depreciation, based on age and upkeep, yields Replacement Cost New Less Depreciation (RCNLD).
- Sales Comparison adjusts RCNLD by analyzing similar properties (physical traits, location, social/economic conditions) to determine Fair Market Value.
What’s Stored in CAMA
- Property photos and building sketches.
- Detailed valuation reports (siding, bathrooms, square footage, etc.)
- Sales data used to value unsold properties.
Legal Validation
The Wyoming Supreme Court affirmed the credibility of the CAMA system in Gray vs. WY SBOE, Decision No. 94-19 (June 9, 1995).
Benefits of CAMA
- Increased statewide uniformity in valuations.
- GIS integration for spatial analysis.
- Enhanced auditing and performance analysis.
- Secure data handling and reporting tools.
Annual Assessment & Appeal Process
Every year by the first week of May, each property owner receives an assessment schedule that includes:
- Estimated Fair Market Value
- Estimated Assessment
- Estimated Taxes (before and after exemptions)
These estimates are based on the previous year’s mill levies.
For a more details on the appeals process click here.
Working Together
The Assessor’s office views this as a partnership with taxpayers. If a property owner questions their valuation:
- They can initiate an informal appeal with the Assessor’s staff.
- If no resolution is reached, they may file a formal appeal within 30 days of the assessment mailing date.
What’s Available to Review
- Property record cards
- Property summary reports
- Comparable sales data
Our mission is to ensure valuations reflect the best available information.
Formula For Tax Dollars
Fair Market Value x Level of Assessment = Assessed Value. Assessed Value x Mill Levy = Tax Dollars.
Statements of Consideration
Property owner cooperation and participation is key to a fair system of taxation for all Wyoming property owners. The following information is intended to help you understand the importance of the information provided on the statement of consideration. Thank you for your interest.
What is a Statement of Consideration?
Wyoming Statute 34-1-142 requires a statement of consideration be completed whenever a deed, contract or other document transferring legal title is recorded. Information such as the date of sale, purchase price, terms of sale, etc. are required. You will probably complete this document at the time of closing.
I don’t want everyone to know what I paid!
Information on the Statement of Consideration is NOT public information and you are protected from random disclosure by provisions and penalties in 34-1-142. Persons appealing their assessment may review the sales information of properties that were used to determine their fair market value. The review period is only during the 30-day appeal period. Property owners may not further disclose the sales information to other persons or property owners. The sales information may be introduced and revealed to the County Board of Equalization during a formal appeal, but further disclosure is prohibited.
What does the assessor do with the information?
The County Assessor has the complex job of annually determining the fair market value of all the property within the county. To accomplish this, sales information for an area is analyzed to develop adjustments to bring the property to current market value. Through the use of computer programs, information gained from properties that have sold can be used on properties not sold to achieve a fair market value for all properties. Because the sales information is crucial to this analysis, the assessor may need to verify the information with one or more of the parties to the transaction. This may be done by phone, mail or in person.
Why is my assessment schedule higher than what I paid?
Wyoming statute also states an individual statement of consideration shall not, by itself, be used to adjust the assessed value of any individual property. To ensure that sold properties are being valued using the same procedures as unsold, all valid open market sales within a neighborhood are used. Neighborhood boundaries are developed on location, economic forces, governmental and social factors. Within neighborhoods other considerations may be age, type of construction, etc.
Are all sales used in the market studies?
No, only sales that are considered valid open market sales are used. Sales involving foreclosures, relatives, gifts, etc. are generally not used.
I want to pay my fair share. How can I ensure my property value is within reason?
Owner participation is key in the development of accurate values. Property characteristics such as size, construction type, amenities, are collected by field appraisers. Owners are encouraged to review this information to verify its accuracy. Actual sales information is used by the assessor as an indicator of market value. Your assistance in verifying the information is very helpful.
Agricultural Lands
General
Many states have laws regarding the preferential assessment of agricultural land. This means that farm and ranch assessments are usually based on the land’s capability to produce agricultural products. In Wyoming, qualified agricultural land is taxed based on the land’s productivity capability under normal conditions rather than on its’ full fair market value.
Ag Land Definitions
Common questions arise in the classification of agricultural lands. Wyoming uses the following points as criteria:
- As of the assessment date, the land is being used for an agricultural purpose, which includes a.) cultivation of the soil for production of crops; or b.) production of timber products or grasses for forage; or c.) rearing, feeding, grazing or management of livestock.
- The land is not part of a platted subdivision. Except: any lot, unit, tract or parcel not less than thirty-five (35) acres in size used for agricultural purposes within a platted subdivision and otherwise qualifying as agricultural land for purposes of W.S.39-13-103(b)(x). The parcel shall be deemed not to be part of a platted subdivision for purposes of W.S. 39-13-103(b)(B)(II).
- If the land is not leased land, the owner has derived annual gross revenues of not less than five-hundred dollars ($500) from the marketing of agricultural products. If the land is leased, the lessee has derived annual gross revenue of not less than one-thousand dollars ($1,000) from marketing of agricultural products from the subject land.
- The land has been used or employed, consistent with the land’s size, location and capability to produce as defined by the Department’s rules and the “Mapping and Agricultural Manual”.
Determining Productivity
There are three steps that must be satisfied to determine agricultural land productivity value:
- Classification. Identifying property ownership and classifying property types (i.e., urban, suburban, agricultural land, etc.) is the responsibility of the County Assessor ‘s office. The proper identification of property ownership is essential to the agricultural land evaluation process. It determines the ownership boundaries and is the first step in determining land use.
- Land Use. There are three major categories of agricultural land. They are irrigated crop, dry crop, and rangeland. Any, or all three, may be found in any given parcel of land. To properly value each agricultural parcel, these categories must be correctly identified and located. This is accomplished through the use of various materials, including aerial photography.
- Productivity. The following three categories of agricultural land are used in identifying productivity.
Irrigated Crop Land
Tons of all hay per acre is the productivity measurement used for valuing irrigated cropland. This “measurement” is determined from environmental factors that affect the soil’s ability to produce. These “factors,” or limitations, are published in the United States Department of Agriculture, Natural Resources Conservation Service’s Soil Survey – and include items such as precipitation, length of growing season, slope, etc.
Dry Crop Land – Not Applicable in Park County
Bushels of all wheat, per acre, are the productivity measurement used for valuing dry cropland. As with irrigated cropland, this “measurement” is determined by environmental factors that affect the soil’s ability to produce. The “factors,” or limitations, are the same as those used with irrigated cropland.
Range Land
Animal Unit Months or AUMs is the productivity measurement used for valuing rangeland. The term “AUM” is defined as the amount of forage required to sustain a 1,000-pound cow, with or without a calf, for one month.
Determining Value
Once ownership has been identified, land use has been established, and the productive capability has been tabulated for the parcel, a four-step valuation process begins:
- Determine Prices of Agricultural Products. This information is derived from the Wyoming Agricultural Statistics Service’s commodity price data. This information, which consists of all hay, all wheat and grazing prices, is converted to a five (5) year weighted average.
- Capitalization Rate Selection. This rate is based on the Farm Credit Services of Omaha Long Term Portfolio rates, which are also converted to a five (5) year weighted average.
- Determine Net Income. To determine the net income, the unit price of each of the 3 commodities is multiplied times the production per acre. Next, the landlord share is determined, if applicable, then the expenses and production losses are deducted to establish a net income to the landlord.
- Capitalize Net Income. The final step in the process is capitalizing the net income. The formula can be found in the current years ‘Ag Land Valuation Study’.
Figuring the Tax Bill
Wyoming is a fractional assessment state. This means that the taxable value is based on a portion of the full value. In Wyoming, this fractional amount is 9.5% for agricultural property. To arrive at the assessed value, multiply the total land value times 9.5%. The assessed value is then multiplied by the appropriate tax district mill levy to obtain the tax.
Forms
Commercial Personal Property
Commercial Personal Property
In Wyoming, commercial personal property is all tangible items that are used in a business that are not part of the land or buildings. Examples are furniture, computers, machinery, tools, libraries, software, leased equipment, and unlicensed vehicles. Inventory held for resale, licensed vehicles, and irrigation equipment should NOT be reported.
All tangible personal property used in business operations is taxable must be reported.
Commercial personal property is governed by several legal and administrative references in Wyoming:
- Wyoming Constitution, Article 15, Section 11 (a): “All property, except as in this constitution otherwise provided, shall be uniformly valued at its full value as defined by the legislature, in three (3) classes as follows:… (iii) All other property, real and personal…”
- Wyoming Statute §39-13-103(b)(i): “Except as otherwise provided: (A) All taxable property shall be annually listed, valued and assessed for taxation in the county in which located and in the name of the owner of the property on January 1.”
- Wyoming Statute §39-13-103(b)(ii): All property must be valued annually at fair market value, using methods prescribed by the Department of Revenue, in accordance with generally accepted appraisal standards.
- Wyoming Department of Revenue Rules, Chapter 9, Section 6(f)(B): Designates the Wyoming Personal Property Valuation Manual as the official instrument for determining values. This manual includes:
- Personal property category listings
- Trending and depreciation tables
- Additional valuation resources
Manuals can be obtained from the Wyoming Department of Revenue:
122 W. 25th Street, Herschler Building, Cheyenne, WY 82002-0110.
Reporting Procedures
The Park County Assessor is responsible for identifying, valuing, and assessing all taxable personal property not specifically exempt by law. Reporting involves the following steps:
Identification of Businesses
Commercial and industrial entities are identified through various sources such as:
- Sales tax records
- Internet presence
- Advertisements
- Visual observation
- Word-of-mouth
These businesses are added to a historical list within the state’s Computer Assisted Mass Appraisal (CAMA) system. Annual personal property reporting forms are mailed in late November and are due by March 1st of the following year.
Required Information
To ensure accurate assessment, include the following details for each item:
- Description
- Make & Model
- Year Built
- Serial Number
- Installed Cost
- Acquisition Date
- New or Used
Additional costs such as freight, installation, or taxes should be either included in the item cost or listed separately.
Key fields: The most critical fields are Description, Installed Cost, and Date Acquired, as these determine trending and depreciation values.
Property Location
Provide the location where the property is used to ensure it’s assessed in the correct tax district. A separate form is required for each location.
Annual Updates
For returning businesses, the assessor’s office will mail a pre-filled listing based on previous year’s data. Please:
- Make necessary corrections
- Add new assets
- Remove disposed items
- Return updated forms by March 1st
Assessments & Appeals
Owners will receive Assessment Schedules by the 4th Monday in April. These documents detail the market and assessed values of the property.
Informal Appeals may be addressed by contacting the Assessor’s office to address questions of valuation.
Formal Appeals must be filed within 30 days of the mailing date if you disagree with the valuation.
If no report is submitted by a business, the Assessor will estimate a value using the best available information. All filings are subject to on-site audits.
Owner Responsibilities
Accurate and timely reporting ensures fair taxation and supports equal assessment practices as required by state law and the Wyoming Constitution.
Exemptions
Wyoming law allows for certain exemptions to personal property.
SF0048 exempts the first seventy-five thousand dollars ($75,000.00) in fair market value of business property owned by a person in each county. 2025 – SF0048
SF0049, though not an exemption, freezes the trending factor for valuation once the depreciation floor is reached. 2025 – SF0049
Personal property used for pollution and fire control. (W.S. 39-11-105) https://www.wyoleg.gov/stateStatutes/StateStatutes
