Inyo County California

Certain filing time frames must be met as shown below:

• Regular Assessment:  If you are appealing the value of your property as of January 1st of the current year, the filing period is from July 2nd through September 15th.
• Supplemental Assessment:  If you are appealing the value based on a notice sent to you because your property had a change of ownership or new construction, you must file within sixty (60) days of the mailing of the notice or the postmark date of the notice or tax bill, whichever is later.
• Roll Change:  If you are appealing when the Assessor has changed the value on a prior year’s roll, you must file within sixty (60) days of the mailing of the notice or the postmark date of the notice or tax bill, whichever is later.
• Escape Assessment:  If you are appealing the value for property which the Assessor discovered was under-assessed or not assessed on a prior year’s roll, you must file within sixty (60) days of the mailing of the notice or the postmark date of the notice or tax bill, whichever is later.
• Calamity Reassessment:  If you disagree with the value stated on a reassessment notice sent to you because your property was damaged due to a natural disaster or other calamity (e.g. earthquake, flood), you must file within six (6) months of the mailing of the reassessment notice, or the postmark date of the notice, whichever is later.
• Penalty Assessment:  If you are appealing when the Assessor has assessed a penalty, such as for a late filing, you must file within sixty (60) days after the notice of penalty assessment.

View the State Board of Equalization's Assessment Appeals Manual for more information about appeal filing periods.
 

*NOTE: If the final filing date falls on a Saturday, Sunday, or a County holiday, an application that is mailed and postmarked on the next business day shall be deemed to have been filed timely.

Upon hearing all the evidence, the Board is required by law to determine the value of your property, which means that it can leave the value the same, decrease the value, or increase the value of your property. An Assessment Appeals Board is not bound by the value presented by you or the County Assessor.

Appeals boards, with proper evidence, can:

• Lower or raise a property's assessed value
• Remove a penalty assessment imposed by the Assessor
• Reverse a reassessment based on change in ownership or new construction

Appeals boards cannot:

• Reduce your property's assessed value simply because you are paying more taxes than your neighbor
• Remove penalties and interest for late payment or property taxes
• Reduce your taxes due to inability to pay
• Grant or deny exemptions
• Extend filing periods
• Change the decision of other appeals boards
• Rehear an issue already ruled upon

The Board's decision is final, and may only be appealed to Superior Court.

The State Board of Equalization provides a guide on assessment appeals, known as Publication 30 and titled, "Residential Property Assessment Appeals." Although the guide's title indicates that its focus is residential appeals, much of the same information applies to the filing of appeals on virtually any type of property. The guide is attached below. 

The State Board has also produced a video designed to provide information to taxpayers regarding the appeals process. The video is titled, "Your Assessment Appeal," and was developed as a collaborative effort between the Board's Taxpayers' Rights Advocate Office and the County-Assessed Properties Division. The video is available on the State Board of Equalization's website and is divided into segments. 

Finally, the State Board of Equalization has also made available a comprehensive list of frequently asked questions related to the property tax assessment appeals process.
