About This Calculator
The California Tax Calculator helps you estimate your California state income tax liability based on your annual income and filing status. California has one of the highest state income tax rates in the US, with a progressive system featuring 10 brackets ranging from 1% to 13.3%. This calculator uses the official 2026 California tax brackets, standard deductions, and personal exemption credits from the Franchise Tax Board to provide accurate estimates.
California state income tax applies to all residents and to non-residents earning income in California. The tax is calculated on your taxable income after the standard deduction. California does not conform to all federal tax rules -- for example, it treats capital gains as ordinary income and does not allow a deduction for state income taxes paid. Our calculator computes tax by applying each bracket rate to the corresponding portion of your taxable income, then subtracts the personal exemption credit to arrive at your final state tax liability.

How is California state income tax calculated?
California state income tax is calculated using progressive tax brackets. Your annual income is reduced by the standard deduction to arrive at taxable income. Each portion of your taxable income is taxed at the corresponding bracket rate. For example, a single filer earning $80,000 in 2026 pays 1% on income up to $11,079, 2% on income from $11,079 to $26,264, 4% on income from $26,264 to $41,452, and so on up to their highest bracket. The final tax is then reduced by the personal exemption credit.
Does California tax capital gains as regular income?
Yes, California treats capital gains as regular income and taxes them at the same progressive state income tax rates, unlike the federal government which has separate long-term capital gains rates. This means capital gains can be taxed up to 13.3% at the state level in California.
What is the difference between effective tax rate and marginal tax rate?
Your effective tax rate is the average rate you pay on your total income, calculated by dividing your total California state tax by your annual income. Your marginal tax rate is the rate applied to your last dollar of income, which determines the bracket you fall into. For a single filer earning $80,000, the marginal rate might be 9.3% while the effective rate would be lower because portions of income are taxed at lower brackets.
Is this California tax calculator free to use?
