California has the highest state income tax in the US — up to 13.3%. See exactly what you actually take home after all deductions.
California's top marginal rate reaches 13.3% on income over $1 million. For most workers, the effective state rate falls between 4%–9.3%. California also charges SDI (State Disability Insurance) at 1.1% of all wages. Understanding your real take-home is essential for budgeting in a high cost-of-living state.
California has the highest state income tax in the United States — 13.3% on income above $1,000,000. But even for workers well below that threshold, California's tax burden is substantial. A single filer earning $100,000 pays approximately $5,900–$6,500 in California state income tax, plus 1.1% SDI (State Disability Insurance) on all wages with no cap. Combined with federal taxes, a California worker earning $100,000 keeps roughly $67,000–$70,000 — about 68 cents on the dollar.
SDI is the deduction that surprises people most. California's State Disability Insurance tax applies to 100% of wages at 1.1% — there is no wage cap. On a $200,000 salary, that's $2,200 per year just for SDI, on top of state income tax. SDI funds California's paid family leave and short-term disability programs, but the premium is mandatory for all W-2 employees. It shows up on your pay stub as "CASDI."
California's Franchise Tax Board is one of the most aggressive tax authorities in the country. Workers who move out of California must be genuinely domiciled in their new state — California will audit former residents who maintain ties to the state (a home, frequent visits, a California-based employer, a spouse who stays). Simply changing your mailing address is not enough. High earners who relocate to Nevada or Texas frequently receive California residency audits, particularly if they have stock options or bonuses that vested while they were in California.
Despite the high taxes, California's job market — particularly in tech, entertainment, and biotech — pays salaries that often compensate for the tax burden. A software engineer at a Bay Area company earning $250,000 pays roughly $30,000 in California state income tax, but may be earning $50,000–$80,000 more than a comparable role in a lower-tax state. The net benefit depends on the salary premium, cost of living, and personal circumstances.

California uses progressive brackets ranging from 1% to 13.3%. The 13.3% rate applies only to income over $1 million. Most middle-income earners fall in the 6%–9.3% range. The standard deduction in California is $5,202 for single filers and $10,404 for married filing jointly — much lower than the federal standard deduction.
SDI stands for State Disability Insurance. In 2026, California charges SDI at 1.1% of all wages with no wage cap — meaning it applies to every dollar you earn. SDI funds short-term disability and paid family leave benefits. It's withheld from every paycheck automatically.
Significantly less at most income levels. A California resident earning $100,000 pays roughly $5,000–$7,500 in state income tax plus $1,100 in SDI that a Texas resident pays $0. The gap widens at higher incomes due to California's steep progressive brackets.
California's minimum wage is $16.50 per hour in 2026 for most workers — the highest statewide minimum in the US. Some fast food workers are covered by a $20/hr industry-specific minimum. Many cities like San Francisco and Los Angeles have even higher local minimums.
No personal income taxes at the city level in California — unlike New York City which adds its own income tax on top of state. However, California does have some city-level gross receipts taxes on businesses, which don't directly affect employee paychecks.
Yes — California taxes most retirement income including 401(k) distributions, IRA withdrawals, and pensions at regular income tax rates. California does not conform to the federal exclusion for Social Security benefits, though Social Security income is currently exempt from California state tax.
California's nominal paycheck may look similar to other states, but high housing costs (especially in LA and the Bay Area), sales tax up to 10.75%, and high gas taxes mean your purchasing power is often lower than the number on your check suggests.

Yes — pre-tax 401(k) contributions reduce your California taxable income in addition to your federal taxable income. This makes 401(k) contributions even more valuable in California than in no-tax states, since you're saving on both federal and state taxes simultaneously.
