Tax Collector

The Tax Collector is responsible for the collection of Secured, Unsecured and Supplemental taxes.

2017 to 2018 Secured Taxes

If you do not receive your secured tax bill by then, please contact our office or call 707-253-4312 to arrange for a duplicate, as failure to receive a tax bill does not relieve your obligation to pay. If you have questions regarding the valuation or ownership of secured properties, please contact the County Assessor's department at 707-253-4467.
