Yes, however, you should first discuss the matter with the Assessor's Office to schedule an informal assessment review. If the matter is not resolved to your satisfaction, there is an Assessment Appeals Board established to formally appeal the assessment. Appeals must be filed within sixty (60) days of the mailing date shown on the Notice of Supplemental Assessment sent by the County Assessor’s Office.
If you are appealing your assessment, your Supplemental Tax Bill(s) should be paid before they become delinquent. If left unpaid, penalties may accrue during the appeal process. If the outcome of your appeal results in a refund, it will be issued by the Auditor-Controller's Office.
Further information regarding the appeals process can be obtained by calling (805) 781-5080, or writing to: County Clerk, Room D-120, County Government Center, San Luis Obispo, California, 93408. Assessment Appeals
