California charges 1-13.3% state income tax. Use the rsu tax calculator pre-loaded with California rates.
Open RSU Tax Calculator →RSU vesting in California triggers up to 13.3% state income tax, treated as ordinary income just like your salary. Your employer typically sells shares at vesting to cover the combined federal, state, and FICA withholding, which can consume 35-50% of the vested shares depending on your income level. This calculator shows you exactly how many shares (or dollars) you keep after all California tax layers are applied.
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.
