About Us

Who We Are

Property Tax

Property taxes (ad valorem tax and special assessments) are collected by the County, but governed by California State Law. Taxes are collected by the Tax Collector's Office on behalf of the County, incorporated cities within the County, school districts, special assessment districts, and other taxing agencies. Once collected, the Property Taxes & Assessments Division of the Auditor-Controller's Office distributes these tax revenues to the various entities.

What We Do

The County Auditor-Controller's Property Taxes & Assessments Division computes the amount of tax due by multiplying the taxable value of the property by the applicable tax rate. The tax rate is equal to one percent (1%) plus bonded debt for the location of the assessed property.

It is the responsibility of the Auditor-Controller's Property Tax Division to allocate and distribute the collected tax revenues to the various taxing entities and special assessment districts.
