Understanding California Income Tax
California has a progressive state income tax system with brackets ranging from 1% up to 13.3% (and higher with mental health service taxes for million-dollar earners). It typically has the highest top marginal income tax rate in the United States.
How Progressive Tax Works
In a progressive tax system, you do not pay the highest rate on your entire income. Your income is divided into brackets, and you pay the specific rate only on the income within that bracket.
