What the ballot measure does
This wizard first scores the one-time wealth tax, then optionally adds future California income tax effects.
The measure would impose a one-time 5% tax on net worth above $1 billion for California residents as of January 1, 2026. Wealth is measured on December 31, 2026.
It phases in from 0% at $1.0 billion to 5% at $1.1 billion, excludes directly held real property from net worth, and lets taxpayers either pay with the 2026 return or in five annual installments with a 7.5% nondeductible deferral charge.
