California Income Tax Calculator
Estimate how much income tax you'll pay in California — federal, FICA and California state income tax. California has some of the highest top rates in the country.
Estimate only. Based on 2024 federal brackets, FICA and an approximate average state rate. Your exact tax depends on deductions, credits and local taxes.
California state income tax
California income tax is progressive, from 1% up to 13.3% (the top rate hits very high earners). This calculator uses an approximate effective state rate for a quick estimate.
Local taxes & other deductions
California also collects State Disability Insurance (SDI) through payroll, withheld separately from income tax and not included in this estimate.
Effective vs. marginal tax rate
Your marginal rate is the tax on your next dollar of income — the top federal bracket you reach. Your effective rate is your total tax divided by your income, which is always lower because the first brackets are taxed at lower rates. The calculator above shows both.
