About the California Tax Bracket Estimator

California uses a progressive income tax system with some of the highest marginal rates in the country, ranging from 1% to 12.3% for most filers, applied in tiers to different slices of income.

Formula: Total Tax = ∑ (income within each bracket × that bracket's rate)

This calculator uses simplified 2024 California single-filer brackets for illustration and excludes California's additional 1% Mental Health Services Tax on income over $1 million, along with credits and deductions that would affect your actual liability.
