When can I expect to have your office complete an onsite inspection?
We physically inspect all properties within Big Horn County every six years. We also inspect properties when there is a sale, a building permit is issued or address assigned. Inspections are done as deemed necessary if you disagree with the value established by the Assessor's office; also, upon request of the property owner.

What should I do if I disagree with the value on my assessment?
You must contact the Assessor's office within 30 days of the mail date on the assessment schedule. Bring with you any information that you would like the Assessor to consider regarding the value of your property.

Why did my value change?

Procedures for Fair Market Value

How does the Assessor acquire actual sales prices?
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 the sale, purchase price, terms of sale, etc., are required. This information is not public.

Can I review sales information?
Persons appealing their assessment may review the sales that were used to determine the fair market value of their property. The review period is limited to the 30-day appeal period. The property owners may not further disclose the sales to other persons. The sales information may be introduced during a formal appeal, but further disclosure is prohibited.

Can I get a copy of the appraisal?
Field appraisers do not determine value. The characteristic information they collect along with sales information will be used to calculate the estimated fair market value for next assessment year. If you are interested in getting a copy of the sketch and characteristics, please contact the office either by phone or visit and we would be happy to give you a copy. Actual calculations made to determine your property value for property tax purposes are available when assessment schedules are mailed.

I called your office and they told me there was more than just one market value. Is that right?
That is correct. Market value is simply an opinion of value. There is no one correct answer. The value determined by our office is as of January 1 of each assessment year. The state of Wyoming has statutes and rules that this office must follow to determine the value of all properties.

Will my taxes go up if the market value of my property increases?
Fair market value is only a portion of the formula for calculating tax amount. The formula for determining actual tax dollars is as follows:

  •    Fair Market Value x Level of Assessment = Assessed Value
  •    Assessed Value x Mill Levy = Tax Dollars

What is the level of assessment in Wyoming?
The level of assessment is the percentage of the market value that determines the assessed value. In Wyoming, the level of assessment for minerals is 100%, industrial use properties is 11.5%; and all other properties 9.5%. This percentage is determined by the legislature.

What is a Mill Levy?
This is the number of dollars in taxes that a property owner must pay for every $1,000 of assessed value. The County Commissioners establish the total mill levy for each tax district based on budget requests from the various taxing entities within the districts boundaries.

How is the Mill Levy determined?
In order to determine the mill levy for each tax district, taxing entities must submit their final budget requests. The budget, less anticipated revenues from non-property tax sources, is divided by the assessed value to obtain the tax rate or mill levy. Assessed values determined by the assessor and values of state assessments (those industries valued by the Department of Revenue, such as utilities, minerals, etc.) are combined to determine the total assessed value within the taxing entities boundaries. An individual assessed value is multiplied by the total mill levy for the tax district to obtain an individual tax amount.

What are tax districts?
They 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
