On los-angeles.com, Mr. Kimmel reviews the figures and the calculation behind the LA County property tax estimator: the Proposition 13 base year value and its annual cap, the homeowners' exemption and what it is worth, the supplemental assessment and its proration, and what does and does not trigger a reassessment. On October 16, 2026 he reviewed the estimator against the State Board of Equalization's own publications and returned corrections that were applied before his name appeared on any page.
