The calculator takes your total taxable income (including capital gains), applies California's 2025-2026 tax brackets (ranging from 1% to 12.3%), and calculates your total California tax. If your taxable income exceeds $1,000,000, it also adds the 1% Mental Health Services Tax surcharge. The effective rate shows what percentage of your total income goes to California taxes.
