Filing Your Assessment Appeal

An assessment appeal is initiated by the applicant by filing an  Assessment Appeal Application  and is necessary for due process if the assessed value of a property cannot be agreed upon with the County Assessor. Ventura County’s Assessment Appeals Board is a quasi-judicial body consisting of impartial persons or a Hearing Officer, who hears evidence from both parties (Assessor’s Office and the applicant) before deciding upon the value of the property in question. The assessment appeal process provides for the ’equalization,’ or the fairness of the assessment of a property’s value. 

The Clerk of the Assessment Appeals Board will send a notice of hearing with the date, place and time of your hearing at least 45 days in advance. You are required to give notice of intent to appear at your scheduled hearing by returning a “Hearing Date Confirmation Notice” to the Clerk of the Assessment Appeals Board no less than 30 days prior to your scheduled hearing date on the hearing notice. It is important you come to your hearing fully prepared to present evidence to support your opinion of value.

 Assessment Appeal Application

The Assessment Appeal Application Form contains sections requesting all the information required to file an assessment appeal.

A separate Assessment Appeal Application Form must be filed for each parcel and each assessment roll year eligible for appeal. Please read the information and instructions on the Application for further clarification.


If you do not have this information, contact the Assessor’s Office at (805) 654-2181.

*The Representative/Agent section should only be filled out if you have authorized a representative, such as a professional tax agent or attorney, to represent you with your appeal. If not, leave this section blank. You must complete the required information for all other sections.

Filing an “Assessment Appeal Application” does not waive your requirement to pay property taxes.

Failure to pay property taxes by the date due will result in penalties and fines.

A successful Assessment Appeal will result in a refund of taxes over-paid.

Failure to complete the application by not providing the required information may result in a delay of process, rejection and/or denial of the appeal.

 Decline in Value (Prop 8)

The decline in value allows a temporary, reduced value of the property, due to a decline in market value. To qualify, the market value of your property as of January 1 must be less than the current enrolled factored base year value. The factored base year value is the value assigned at the time of purchase or new construction, changed at a rate not exceeding 2% per year. A value assigned to the property under the Decline in Value law affects only the current tax year; therefore, Decline in Value appeals must be filed annually.

Discussing the appraisal of your property with the Assessor’s office will assist you in understanding the methods and the market data used in determining taxable value. This consultation may lead to a value resolution prior to the hearing.

The Assessor’s Office will directly request information from the applicant regarding the subject property under section 441(d) of the Revenue & Taxation Code.

Once you have formally filed an Assessment Appeal Application, and up to any time prior to 30 days before your scheduled hearing, you or the Assessor’s Office (if subject property has an assessed value over $100,000) may request an exchange of information as set forth in the Revenue and Taxation Code Section 1606.

Be prepared to present your market evidence at your scheduled hearing to support your opinion of value.

The Assessment Appeals Board can decrease, increase, or sustain (not change), an assessment.

If you have questions about your property assessment,
please call the Assessor’s Office at
(805) 654-2181
to speak to an appraiser.

 Assessment Appeals Clerk

The Clerk of the Assessment Appeals Board is the intermediary in the Assessment Appeal process. They receive Assessment Appeal Applications from taxpayers seeking a reduction in property value assessments and ensures that applications meet the requirements of California State Board of Equalization Rules and Revenue & Taxation Code. The Clerk of the Assessment Appeals Board also assists taxpayers’ inquiries regarding their applications and appeal hearing procedures.

In addition to the Clerk of the Assessment Appeals Board providing you notification of your hearing, a “Preparing for Your Hearing” brochure will be included. The brochure will provide information regarding appearance at your hearing, evidence, and hearing procedures.

The “Preparing for Your Hearing” brochure information is available online or you may request a copy from the Clerk of the Assessment Appeals Board.

Assessment Appeal Applications,

While the Clerk of the Assessment Appeals Board is tasked with many duties related to the functions of the assessment appeals process, the Clerk is not responsible for property assessments, tax bills or notices, tax payments, or refunds of taxes paid.

 Hearing Board vs. Hearing Officer

Determinations of value are made by either a three member Assessment Appeals Board or a Hearing Officer. These individuals are appointed by the Board of Supervisors to serve as the local board of equalization. Typically a Board Member has experience as an appraiser, real estate broker, certified public accountant, attorney, or knowledge of the real estate market. A Board Member’s role is to determine the value of your property based only upon evidence presented by you and the Assessor’s Office representative at your hearing.

Having your case heard before a Hearing Officer (only available for properties with values under $500,000 or is a single family residence, condominium, cooperative, multiple family residence of four units or less) is considered an expedient and convenient alternative to the formal Board quasi-judicial proceedings. However, if you wish to have Findings of Fact prepared, you must have your case heard before the three member Assessment Appeals Hearing Board and, at the time of hearing, pay the appropriate Findings of Fact fee.

Return to Top

 Findings of Fact

Findings of Fact are a brief summary of your case showing the basis for the Assessment Appeals Board’s decision and are required if you intend to pursue judicial review in Superior Court to reverse the Board’s decision.

You are required to request Findings of Fact from the Clerk of the Assessment Appeals Board prior to the commencement of the hearing.

Do not submit payment until your hearing begins.
The valuation issue could be resolved prior to hearing making an advanced payment unnecessary.


$100 if the total assessed property value is less than $200,000
$150 if the total assessed property value is more than $200,000.

 Designating Your Application as a Claim for Refund

If you designate your Assessment Appeal Application as a Claim for Refund, and your assessment is reduced at your hearing, the County of Ventura will automatically process the refund for you. However, if your application is not designated as a Claim for Refund, you may be required to submit a separate ‘Claim for Refund’.

Not Designating Your Application as a Claim for Refund

A disadvantage of having your Assessment Appeal Application designated as a Claim for Refund is that it may shorten your time to make a decision regarding whether to pursue your claim in Superior Court if the outcome of your hearing is not in your favor. You must file your claim in Superior Court within 6 months of the date of the Assessment Appeals Hearing Board’s decision.

If your application is not designated as a Claim for Refund, you will have 6 months from the Assessment Appeals Hearing Board’s decision to file a Claim for Refund with the County of Ventura. Then, you will have 6 months from the time the County of Ventura denies your claim to file your claim in Superior Court.
