Tax Collector

The Office of the Tax Collector is responsible for the billing, collections, record management and receipt reconciliation of Secured, Supplemental and Unsecured property taxes. The Tax Collector’s staff is available to assist individual taxpayers and mortgage professionals with questions regarding tax status, defaulted or delinquent tax payments, lot line adjustments, tax clearances, mobile homes, and payment plans for delinquent property.


Secured taxes are levied on real property, such as land and structures attached to land. Unsecured taxes are based on the value of personal property, such as business fixtures, boats and aircrafts. Supplemental taxes are an adjustment in the value of real property.


Melinda Casillas is also the County Treasurer and the Public Administrator.






It recently came to our attention that not all the voter approved special assessment charges were included on your 2019-2020 Secured Tax bill. A technical error occurred with the county’s third party property tax software during file transmission. Corrected bills are in the process of being printed and will be mailed to you shortly. If you have already paid one or both installments, you will receive a new bill only for the difference. If your lender forwards your payment to us, we will notify them of the correction. The corrected amounts are available on-line.


If you have any questions, please contact our office at 831.636.4034 or by email at


We apologize for this confusion, and thank you for your patience and understanding.
