Don Gackel, chair of the California County Assessor Information Technology Authority joint powers authority, briefed the State Board of Equalization on Oct. 22 on the JPA’s formation, funding and procurement progress toward a statewide Prop 19/exemptions portal.
Gackel said the authority was formed under Revenue and Taxation Code 95.6 and that the state provided three installments of $10 million (2022, 2023 and 2024) to support county technology projects. "We created a joint powers authority on 11/15/2022," Gackel said, and the membership has grown from 16 to 33 counties.
The JPA completed a proof of concept in 2024 and issued a production RFP on April 28, 2025. Gackel said four vendors submitted proposals; three were selected to proceed to contract discussions after written evaluations and oral presentations. He named Oracle and Tyler Technologies among the finalists and said the committee will negotiate contracts with the top candidates to secure the best terms before returning with a final recommendation.
The JPA told the board the procurement seeks a flexible system so counties may participate at different levels — from full portal adoption to limited interoperability for exchange of Prop 19 and exemptions data. Gackel said the authority’s funds are invested with CalTrust and that the JPA has engaged Gartner and other consultants for advisory and project management services.
Why it matters: Assessors and BOE staff said a standard statewide portal could reduce errors, speed exchanges of base‑year transfer and exemption data, and support more consistent administration of Prop 19 across 58 counties. The JPA’s model and vendor work could also provide a template for a future statewide assessment appeals portal if funding and clerks of the board leadership align.
No formal board action or vote occurred; the JPA report described progress and next procurement steps.
