Welcome to the County of Santa Clara, Clerk of the Board’s Assessment Appeals website. Assessment Appeals is an independent function, separate from the Assessor's Office, established to decide disputes on property assessed values between the Assessor's Office and property owners.
A separate application must be completed and filed for one type of assessment for each parcel of real property or each assessment of personal (unsecured) property for one tax year.
Starting 7/14/14, you can complete and submit your assessment appeal application (Application for Changed Assessment form) online by selecting the Appeal Online button below, register for a PIN to electronically sign, and add PDF attachments. The system will assist you in filling out your form accurately and completely. You will receive an appeal case number, and you can print your appeal application for your records.
Value Hearing Officer Option
What is the difference between the Assessment Appeals Board and the Value Hearing Officer?
The Appeals Board is a three-member panel and the hearings have a more formal courtroom atmosphere, while a hearing with the Value Hearing Officer is less formal. The Value Hearing Officer is a real estate professional who hears residential valuation appeals. Having your appeal scheduled before a Value Hearing Officer is considered an expedient and convenient alternative to the more formal Board proceedings, and may provide a faster resolution to your appeal. To choose this option when completing your application, check the "Yes" box in item #9 on the application. For more information click on the Value Hearing Officer Proceedings Brochure below.
