Agricultural land in Wyoming is valued by the local County Assessor. The Department provides guidance, in the form of administrative rules and the Mapping & Agricultural Manual for the assessors and their staff. The Property Tax Division also publishes the annual Agricultural Valuation Study that establishes the ranges of value for range land, irrigated and dry crop lands to be utilized by the County Assessor in determining agricultural land value.
Appeals must be filed with the County Assessor in which your property is located no later than 30 days from the date of the Assessment Notice. Your appeal must address the issue of market value, not the tax rate. Evidence supporting your estimation of the market value must be included in the appeal (for agricultural land value appeals, the taxpayer may need to provide yield information, stocking rates, or other relevant information as evidence). If you do not agree with the County Board of Equalization’s decision, you may appeal to the State Board of Equalization. Appeals to the State Board of Equalization must be filed within 30 days from the entry of a decision of a County Board of Equalization or upon the date of mailing of the decision as evidence by a legal postmark, whichever is later.
