Appealing Real Property Valuation
The Assessor mails a notice of valuation to real property owners May 1 of each year. If a property owner believes the Assessor has incorrectly valued or classified the property, or that it was not valued fairly as compared to other properties, an appeal may be filed beginning May 1 through June 8. Any mail Appeal must be postmarked no later than June 8, 2023.
Timing is everything
It is better to appeal early in May. The last few days of the appeal period are often very busy and you may experience delays.
How to Appeal an Assessment
To appeal an assessment, you should explain why you believe the assessor’s value is incorrect. It is important that you provide pertinent information supporting your estimate of value. The sales used to develop the current year actual value are listed on the assessor’s web site. By comparing your property to other similar properties that sold, you can determine whether your property has been fairly valued.

What to Expect After You Appeal
If you appeal, we will mail you a notice of determination by Aug. 15 of the year of the appeal. This notice will show the assessor’s office adjustment to value, if any, and explain how to appeal to the county's Board of Equalization (county commissioners) if you are still dissatisfied. You must file your appeal to the Board of Equalization (BOE) by Sept.15. The board must conclude hearings by Nov. 1 and notify petitioners of its decision within five business days.
If you wish to appeal a BOE decision, you must do so within 30 days of the decision. Your options are described in the board’s response.
