Assessment Appeals Board
Differences in opinion over the valuation of property are handled by the Assessment Appeals Board. There are five independent boards, each composed of three private citizens appointed by the County Board of Supervisors. They consider all evidence presented by the property owner and the Assessor at a formal hearing and then determine the value of the property in question.
All appeals must be filed with the Clerk of the Appeals Board at the County Administrative Center, 4080 Lemon Street, 1st Floor, P.O. Box 1628, Riverside, CA 92502-1628. For more information, call (951) 955-1060.
Valuation questions relating to assessment appeals can be directed to the Assessor's Office at (951) 955-6200.
The "Assessment Appeal" form is available on the Clerk of the Board's website.

Frequently Asked Questions
What is an assessment appeal?
An assessment appeal is a process whereby property owners can appeal their property's assessed value to an independent citizen's review board appointed by the Board of Supervisors. This board will review the evidence presented by the Assessor's Office and the taxpayer, and will then establish the taxable value for the property.
When must an assessment appeal be filed?
An assessment appeal can be filed on either the supplemental or the regular assessment. When appealing a supplemental assessment, the appeal must be filed within 60 days of the date of mailing printed on the Notice of Supplemental Assessment or the postmark date on the envelope in which the notice was mailed, whichever is later. When appealing an escape assessment, the appeal must be filed within 60 days of the date of mailing printed on the Notice of Enrollment of Escape Assessment or the postmark date on the envelope in which the notice was mailed, whichever is later [see Revenue and Taxation Code, Section 1605(b)(1)]. When appealing the regular assessment, the appeal must be filed between July 2 and November 30.
If I file an appeal, will I have to appear at the hearing?
If the property owner and the Assessor's Office reach an agreement on the value of the property, as happens in most cases, and sign a written stipulation, no appearance is necessary. However, if an agreement is not reached with the Assessor's Office, the property owner or an authorized agent must appear at the hearing or the case will be denied.
What should I present at the appeal hearing to support my case?
You should present information that helps to support your opinion of market values, such as sales information of comparable properties. Contact the Clerk of the Appeals Board for required number of copies, etc.
Where can I obtain sales information of comparable properties?
As required by state law, the Assessor's Office keeps a listing of all recent sales, and this information is available at all Assessor branch offices as well as the main office at the County Administration Center, 4080 Lemon St., Riverside, CA 92502-2204. Another option is to simply contact a local real estate agent within your area who will normally provide you with recent sales in your neighborhood at no cost.
Will I have to pay my property tax bill if I file an appeal?
Chances are we will not be able to get to your case prior to the December 10th property tax installment deadline. Therefore, you should pay the December 10th installment. If you are successful in getting a reduction in value, you may receive a corrected bill in time for the April 10th installment. If you pay both installments prior to receiving a corrected tax bill, any overpayment will be refunded.
How can I obtain an assessment appeals application?
The necessary application for filing an assessment appeal can be obtained by writing the Clerk of the Assessment Appeals Board or by calling them at (951) 955-1060.
