California charges 1-13.3% state income tax. Use the overtime tax calculator pre-loaded with California rates.
Open Overtime Tax Calculator →Overtime hours in California face a combined state and federal marginal rate that can surprise workers. With a top state rate of 13.3% stacking on top of the federal 22% supplemental rate and 7.65% FICA, overtime income can be taxed at over 42.9% at the margin. Understanding this stacking effect is essential before committing to extra shifts. The overtime calculator breaks down exactly how much of each overtime dollar you actually keep.
California uses a graduated income tax with brackets ranging from 1-13.3%. Lower income is taxed at lower rates, with the 13.3% top rate applying only to income in the highest bracket. This progressive structure means your effective state tax rate is always lower than the top marginal rate. California does not have local income taxes, so the state graduated rate is the total state-level income tax burden.
The table below shows what you actually keep at five salary levels in California, accounting for federal tax, FICA, and California's graduated (1-13.3%) state tax.
