How to Complete the Appeal Form

The State Board of Equalization, in cooperation with Orange County, has prepared a pamphlet to assist you in completing this application. You may download a copy of Publication 30, Residential Property Assessment Appeals, at

Filing this application for reduced assessment does not relieve the applicant from the obligation to pay the taxes on the subject property on or before the applicable due date shown on the tax bill. If a reduction is granted, a proportionate refund of taxes paid will be made by the county.

Based on the evidence, the Appeals Board can increase as well as decrease an assessment. The decision of the Appeals Board upon this application is final; the Appeals Board may not reconsider or rehear any application. However, either the applicant or the assessor may bring timely action in superior court for review of an adverse action.

An application may be amended until 5:00 p.m. on the last day upon which the application might have been timely filed. After the filing period, an invalid or incomplete application may be corrected at the request of the clerk or amendments may be made at the discretion of the board. Contact the clerk for information regarding correcting or amending an application.

The Appeals Board can hear matters concerning an assessor's allocation of exempt values. However, it cannot hear matters relating to a persons or organization's eligibility for a property tax exemption. Appeals regarding the denial of the Welfare Exemption should be referred to the State Board of Equalization, Policy, Planning, Assessment Policy and Standards Division, MIC:64, PO Box 942879, Sacramento, CA 94279-0064. Appeals regarding the denial of any other type of exemption are under the jurisdiction of the County Assessor and/or the courts.

Box 6

Please mark the item or items describing your reason(s) for filing this application. If you prefer, you may attach one copy of a brief explanation. You are not required to provide evidence with this application. If you selected DECLINE IN VALUE, be advised that the application will only be effective for the one year appealed. Subsequent years will normally require additional filings. In general, BASE YEAR is either the year your real property changed ownership or the year of new construction on your property; BASE YEAR VALUE is the value established by the Assessor at that time. The base year value may be appealed during the regular filing period for the year it was placed on the roll or during the regular filing period in the subsequent three years. IF YOU ARE APPEALING BOTH A DECLINE IN VALUE/PROP 8 AND A BASE YEAR VALUE, BE SURE TO CHECK BOTH BOXES. YOU WILL NEED SEPARATE EVIDENCE TO SUPPORT EACH APPEAL.

CALAMITY REASSESSMENT includes damage due to unforeseen occurrences such as fire, earthquake, and flood, and does not include damages that occur gradually due to ordinary natural forces. A penalty assessed by the tax collector for nonpayment of taxes CANNOT be removed by the appeals board.

PERSONAL PROPERTY/FIXTURES: Indicate whether you are appealing an item, category, or class of property or a portion thereof. If you are appealing only an item, category, or class of property, please attach a separate sheet identifying what property will be the subject of the appeal.

APPEAL AFTER AN AUDIT must include a complete description of each property being appealed, your opinion of value for each property appealed, and the reason for the appeal.

Contact the clerk to determine what documents must be submitted. If you do not submit the required information timely, it will result in denial of your application.

Box 7

Findings of fact can only be requested if you are heard before a Board. Written findings of facts are explanations of the Appeals Board's decision and will be necessary if you intend to seek judicial review of an adverse Appeals Board decision. Findings may be requested in writing and paid for at the commencement of the hearing. Requests for a tape must be made no later than 60 days after the final determination by the Appeals Board. You may contact the clerk to determine the fee for these items; do not send payment with application. Arrangements for written transcripts must be made by each party at the party’s own expense. The Clerk of the Board should be notified no later than 72 hours prior to the commencement of the hearing, so that seating accommodations can be made for the person providing the transcript. A copy of the transcript shall be made available upon completion to the Clerk of the Board for the record at no charge.

Box 8

Indicate whether you want to designate this application as a claim for refund. If action in Superior Court is anticipated, designating this application as a claim for refund may affect the time period in which you can file suit. NOTE: If for any reason you decide to withdraw this application, that action will also constitute withdrawal of your claim for refund.

Box 9

If your property is a single family dwelling, condominium, or townhouse a hearing officer can consider your appeal. It should be noted that Findings of Facts are not available when your appeal is heard before a hearing officer. Although you select a hearing officer, that option may not always be available. Every attempt will be made to accommodate your request.

If the assessed value of the property exceeds $100,000, the assessor may initiate an "exchange of information" (Revenue and Taxation Code section 1606). You may also request an "exchange of information" between yourself and the assessor regardless of the assessed value of the property. Such a request may be filed with this application or may be filed any time prior to 30 days before the commencement of the hearing on this application. The request must contain the basis of your opinion of value. Please include comparable sales, cost, and income data where appropriate to support the value. In some counties, a list of property transfers may be inspected at the assessor's office for a fee not to exceed $10.00. The list contains transfers that have occurred within the county over the last two years.

Original signatures are required for each application. Check the box that best describes your status as the person filing this application and sign in blue ink.
