Los Angeles County Treasurer-Tax Collector

What Los Angeles County Treasurer-Tax Collector does

Los Angeles County Treasurer-Tax Collector is a constitutional county office established in 1850 with the formation of Los Angeles County, operating under California state law as part of the county's governmental structure. The office is responsible for billing, collecting, disbursing, investing, borrowing, and safeguarding public monies and properties associated with property taxation in Los Angeles County. It serves all property owners in the county — both residential and commercial — and operates alongside the Assessor, Auditor-Controller, and Assessment Appeals Board, with Elizabeth Buenrostro Ginsberg currently serving as Treasurer and Tax Collector following her 2021 appointment. The office has approximately 52 employees and operates from the Kenneth Hahn Hall of Administration in Los Angeles, with a separate Unsecured Property Tax Section office.

The office delivers services through a multi-channel model including an in-person public counter, telephone support, mail correspondence, and a digital Property Tax Portal (propertytax.lacounty.gov). Core service lines cover Secured Property Tax (real property), Unsecured Property Tax (personal property such as business equipment and watercraft), penalty cancellation requests, installment payment plans, senior citizen assistance, and the public auction of tax-defaulted properties. The portal offers self-service tools for duplicate bill requests, payment history lookups, and e-notification via GovDelivery, and is published in nine languages. The office is funded through county budget appropriations rather than commercial revenue, and property tax collections are public funds belonging to the county, not the office's revenue.

The technology stack is non-proprietary and limited to widely available third-party tools: Google Analytics for site analytics, Google AdSense for advertising, and GovDelivery for email notifications. The portal achieves WCAG 2.1 Level AA and ADA Title II accessibility compliance. There are no patents, proprietary AI/ML systems, or venture-style product launches documented. Strategic activity in recent years has centered on leadership transition in 2021, digital modernization of the portal, multilingual service expansion, and accessibility compliance rather than market-facing innovation.
