An “Assessment Appeal Application” is a formal challenge of a property’s assessed value established by the Assessor’s Office. By filing an Assessment Appeal Application, you are disagreeing with the Assessor’s assessed value and are requesting a hearing before either an Assessment Appeals Board or Hearing Officer. Please be prepared to submit information supporting your opinion if requested by the Assessor’s Office and at the appeal hearing proving the Assessor’s Office value is incorrect. The Assessment Appeals Board or Hearing Officer will only consider relevant evidence that is presented at the appeal hearing, which is an open public meeting. To assist you in understanding the appeal process and prepare for an appeal hearing, it is strongly recommended you review the Resources and Literature section, below.
Additionally, it is important to know an Assessment Appeals Board or Hearing Officer can decrease as well as increase or sustain (not change) an assessment based on the evidence presented at the appeal hearing.
The Deadline to file an
Assessment Appeal Application,
for the January 1, 2018 Regular Assessment is,
Monday, September 17, 2018
Applications being sent by mail must have a U.S. Postal Service Post Mark date
September 17, 2018 or earlier.
Applications being delivered in person must be received before 5:00 p.m.
Applications CAN NOT be submitted by E-Mail or Fax.
You may resolve your Assessment issues and questions Independent of the Assessment Appeal process.
If you disagree with the property’s assessed value (the January 1 Regular Assessment of property value),
you have the right to contact the Assessor’s Office directly at (805) 654-2181
and request an Informal Assessment Review.
An Informal Review is not a formal appeal and does not extend the deadline to file a formal appeal.
** For Supplemental, Escape, and Roll Change Assessments, see below for filing deadlines. **
Deadlines for Filing an Application Appealing an Assessment
Below are the different types of Assessments, Notices, or Bills you may receive.
Select the applicable Assessment type to view the deadline to appeal. The Assessment type should be indicated in the title of the Notice/Letter received from the Assessor’s Office.
Regular Assessment (Assessed Value as of January 1, 2018):
An Assessment Appeal Application must be submitted starting July 2, 2018 through September 17, 2018. Assessment Appeal Applications mailed on September 17, 2018 must be postmarked that day to be considered as timely submitted.
The Regular Assessment is the property value calculated Annually as of January 1, and shown on the Notice of Assessment issued to you by the Assessor before August 1 of each year, and then shown on the Annual Tax Bill issued in October.
It may be easier to complete your Assessment Appeal Application after you receive the annual notice from the Assessor, but you are not prohibited from appealing the Regular Assessment so long as the Regular Filing period is open. If you do not receive a notice of Assessment by August 1, you should call the Assessor at (805) 654-2181 to verify your mailing address, find out what your Assessed value is, and Request a copy of the Assessment Notice if necessary.
Supplemental Assessment, Assessment Roll Change, and Escaped Assessment:
An Assessment Appeal Application must be submitted within 60 days of the date the notice was mailed by the Assessor’s Office, which is printed on the notice of assessment, or the envelopes postmark, whichever date is later.
These notices are typically titled Notice of Supplemental Assessment, Notice of Enrollment of Escape Assessment, Assessment Roll Correction, or Assessment Roll Change.
Please note, an Assessment Roll Change or an Assessment Roll Correction that is a reduction may not be eligible for appeal.
An Assessment Appeal Application must be submitted or postmarked within 6 months of the date the notice was mailed by the Assessor’s Office, which is printed on the notice of assessment.
Calamity Reassessments are issued after major natural disaster destruction to a property, such as a Wildfire, Flood, or Earthquake. If the Assessor denies to complete a Reassessment due to a catastrophic event, because they believe it does not qualify, that decision can not be appealed. Only after the Assessor issues a new value due to a qualifying catastrophic event, then you can appeal within 6 months of the notice of reassessment.
Base Value / Base Year
The Base Value of a property is the value that establishes the maximum taxable value as regulated by Proposition 13, and increased annually by an amount not to exceed 2%, as determined by the California State Board of Equalization. A Base Value change is tied to a specific date, is permanent, and has a limited window to file a formal appeal. Below are some examples of a Base Value change.
Appeal of a Base Value
The notice of a Base Value change is called a Notice of Supplemental Assessment, received from the Assessor’s Office. The time limit to appeal is 60 days from the date printed on this notice. If you disagree with a Base Value, appealing within the 60 days of the Notice of Supplemental Assessment is the ideal situation for maximum possible tax relief.
If the 60 day deadline to appeal is missed, there is a second chance to file an appeal. A Base Value change can be appealed during the Regular Filing period of the following 4 years after the Assessment is enrolled by the Assessor. See the tab on Regular assessment for the Regular Filing Period dates. This is not ideal, as any potential tax relief would only apply beginning in the year the application was filed, and not go back to prior years. This is known as a Prospective Base Value Appeal. As any tax relief would only apply beginning with the year the application is filed, you should file as early as possible within the 4 year window. After 4 years has passed, a Base Value can no longer be appealed.
Why was a new Base Value Established?
Change of Ownership Reassessment
When an event occurs that results in partial or full change in control of a property, the Assessor may issue a reassessment typically effective as of the date of a document being recording or the date of a death. The Assessor determines a new market value of the property as of this date. If there was a 100% change of ownership, a full market value will be Enrolled by the Assessor. If there was a partial change of ownership, the Assessor will Enroll a blended value, combining the old Base Value and the new Base Value.
You can appeal the Assessor’s determination that the property changed ownership, if you believe the property should not have been reassessed due to qualifying exclusion. This is done on the Assessment Appeal Application in section 6, by marking Box B-1.
You can appeal the Assessor’s Value determination as well, if the value they enrolled is not what you believe to be a fair market value as of the event date. This is done on the Assessment Appeal Application in section 6, by marking Box B-2. Please note, if the Assessor Enrolled your full purchase price as a Base Value, this is typically considered correct and very difficult to challenge. Please review California State Board of Equalization’s Property Tax Rule 2 for more information on how value as of a purchase date is determined.
New Construction Reassessment
When construction is completed on a property, this is an event that qualifies for a permanent increase in the Base Value. The Assessor typically adds the full market cost of construction to the Assessed value, and establishes the new Base Value. The event date is typically tied to the date construction is completed. This can be appealed on the Assessment Appeal Application in section 6, by marking a selection under “C”.
Deadlines can not be extended. If you are uncertain of the applicable deadline, please call the Clerk of the Board to confirm at (805) 654-2251.
Do not wait to receive a Tax Bill to appeal, it may be too late by the time a Tax Bill is issued.
Your Deadline to appeal may also be noted on the back of the notice received.
Applications are generally resolved in the order received, so it is in your best interest to file as early as possible, within the applicable time period.
*Please Note: If the final filing date falls on a Saturday, Sunday, or a legal holiday, an application that is mailed and postmarked on the next business day shall be deemed to have been filed timely.

Professional Tax Agent Requirements
An Application may be filed by a person holding title to the property being appealed, or such person’s Spouse, Parent, or Child. Any other person filing the appeal on your behalf, or representing you in the Assessment Appeal Process is referred to as the Applicant’s Authorized Representative or Agent. There are numerous private companies that will act as your Agent, usually for a fee. Such Agents are considered Professional Tax Agents.
Authorizing a professional tax agent to represent an applicant with an Assessment Appeal is optional and not required to file an appeal. You can also Remove or Change your Representative at any time prior to a Hearing being held.
Regulations applicable to Professional Tax Agents are strictly applied in Ventura County. If you are a Professional Tax Agent, or an Applicant who will be appointing an Agent, click to read more on the requirements that must be met.
In addition to completing an Assessment Appeal Application and filing it within the appropriate filing period as stated above:
The Professional Tax Agents authorization in section 2 of the Assessment Appeal Application must be completely filled and contain an original signature at the time the application is submitted to the Clerk of the Board. DO NOT SUBMIT A COPY.
An attached agent authorization meeting all requirements stated on the State of California, Board of Equalization’s Property Tax Rule 305 must be submitted with the Assessment Appeal Application at the time the application is submitted to the Clerk of the Board.
Business and Professions Code 17537.9 requires Professional Tax Agents authorized to represent an applicant to keep an originally-signed copy of all authorizations on file for 3 years. If authorizations look questionable, the Assessment Appeals Board or Hearing Officer may request the original Agent Authorization on file with the agent be provided at the Assessment Hearing.
AUTHORIZATION OF AGENT OR DESIGNATION OF ATTORNEY FORM – For your convenience, the County of Ventura has an Agent Authorization form that can be used by Professional Tax Agents to file an Assessment Appeal. When fully completed, this form meets all requirements of the law.
