How California income tax works
California uses marginal brackets. Income in each band is taxed at that band's rate, so reaching the 13.3% bracket does not cause all of your income to be taxed at 13.3%. Your effective rate is normally lower than your highest marginal rate.
California's 13.3% top rate (including the 1% mental-health surtax above $1 million) is the highest state income tax rate in the US. Filing status matters because bracket widths, deductions and exemptions may differ for single and married filers. Use these rates for comparison and planning, then confirm your return with the current instructions from the California tax agency.

These examples apply a 7.15% planning rate to gross pay to show scale. They are not tax-return calculations and do not include deductions, credits, local taxes or special income rules.
| Annual gross pay | Planning rate | Illustrative annual amount | Monthly equivalent |
|---|---|---|---|
| $50,000 | 7.15% | $3,575 | $298 |
| $100,000 | 7.15% | $7,150 | $596 |
| $200,000 | 7.15% | $14,300 | $1,192 |
Why this is only an estimate: California's actual calculation applies each marginal bracket separately. The calculator uses one adjustable planning rate and does not claim to reproduce a state return.

California income tax FAQ
What are the California income tax brackets for 2026?
California uses graduated rates from 1% to 13.3% in 2026. The top 13.3% rate applies to single-filer taxable income above $1,000,000. California's 13.3% top rate (including the 1% mental-health surtax above $1 million) is the highest state income tax rate in the US.
What does "graduated" or "marginal" mean for my California taxes?
Like the federal system, only the income inside each bracket is taxed at that bracket's rate — crossing into a higher bracket never lowers your take-home pay. Your effective (average) rate is always below your top marginal rate.
What rate should I use to estimate California withholding?
A single flat approximation between 1% and 13.3% works for rough planning — the right number depends on your income level. Our prefilled paycheck calculator starts you at 7.15%, which you can adjust up or down.
