Appealing your Notice of Assessment
If you disagree with the fair market value of your property on the Notice of Assessment, you have 30 days from the postmark date on the envelope to make an appeal. The first step is to either call the Assessor's Office at (307) 872-3700 or come by the Assessor's Office. When you call or come into the office, the Assessor reviews your property file and verifies with you that all the property characteristics information is accurate. This includes:
- Square Foot Size
- Finished Area
Any changes may affect the final fair market value. During this review, you may provide any information you would like to have considered such as current appraisals, market analysis, special conditions, or influences that may result in a change in value. Statements of "it's too high" or "it's wrong" are vague and not definable.
For residential properties, the Assessor will review the sales comparables for the property. If you desire, a copy of the sales comparables will be provided, but only during the 30-day appeal period.
Note: Under Wyoming Statute 34-1-142, sales information is not a public record and must be kept confidential. Persons receiving sales information may not disclose it to other individuals. Property owners may disclose this information with the County Board of Equalization in conjunction with any hearing.
Official Appeal of Assessment - General Order of Proceedings
If, after a review, you feel the value of your property is still incorrect, you may file an official appeal with the County Board of Equalization, a board made up of the County Commissioners. Official Appeal of Assessment forms are available in the Assessor's Office. Copies of the form must be filed with the Assessor within 30 days of the postmark date of your Notice of Assessment. An appeal may be withdrawn at any time by written notification to the Clerk's and Assessor's offices.
You are notified by mail once a hearing date and time are set. No later than 15 days prior to the hearing, you (the Petitioner) and the County Assessor must disclose witnesses and exchange information, evidence, and documents relevant to the appeal. This should include anything that is to be presented as evidence during the hearing.
The County Commissioners serve as the County Board of Equalization. Other persons attending the hearing will include the hearing officer, recording secretary, secretary to the board, counsel for the board, and parties to the appeal.
The Petitioner is first to present evidence or witnesses. Any testimony presented may be questioned by the Assessor, the Assessor's attorney, or a member of the board. Next, the Assessor or a representative presents evidence or witnesses. The testimony may be questioned by the Petitioner, his agent, or a member of the board.
After all testimony and evidence is presented, a brief closing statement may be made by each side.
The Board will notify participants in writing of their findings and any appeal action available to them no later than the first Monday in August.
Evidence supporting your estimation of the fair market value must be included in the appeal. 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 after the final action of the County Board of Equalization.
