Estimate your take-home pay after federal income tax, California's graduated state income tax, the new 1.3% SDI, Social Security, and Medicare — salary or hourly.
Results estimate your true annual tax liability spread across paychecks using a simplified annualized method. Actual employer withholding via Form DE-4 / W-4 can differ. California Franchise Tax Board and EDD are the authoritative sources.
California has the most layered wage withholding of any U.S. state: a steeply graduated income tax, the federal income tax and FICA, and a mandatory State Disability Insurance contribution that, since 2024, applies to every dollar you earn. There is no county or city income tax anywhere in California, which slightly offsets the high state rate. Understanding each line on your pay stub helps you confirm it is correct and keep more of what you earn.
Unlike flat-tax states, California taxes income through nine progressive brackets running from 1% up to 12.3%, with an extra 1% Mental Health Services Tax on taxable income above $1,000,000 (a 13.3% top marginal rate — the highest of any state). Your California taxable income is your wages minus pre-tax deductions and the California standard deduction, which for 2026 is $5,706 for single filers and $11,412 for married filing jointly and heads of household. Note this is far smaller than the federal standard deduction, so more of your income is exposed to California tax than to federal tax.

California is one of the few states that withholds a mandatory State Disability Insurance contribution, which also funds Paid Family Leave. For 2026 the rate is 1.3%, up from 1.2% in 2025. The big change happened in 2024: Senate Bill 951 eliminated the taxable wage ceiling. Before 2024, SDI stopped after a wage cap (around $153,164 in 2023); now it is withheld on 100% of wages with no maximum. A worker earning $400,000 pays $5,200 in SDI for 2026 — a line many national paycheck calculators still get wrong because they apply the old cap.
This is one of the most overlooked items on a California pay stub. California does not conform to the federal Health Savings Account rules. Money you route to an HSA through payroll is pre-tax for federal income tax, Social Security, and Medicare — but California adds it back to your state taxable income and taxes it. This calculator applies the add-back, so your California income tax line reflects the real number. (FSA, medical, dental and vision premiums under a Section 125 plan are recognized by California and reduce state tax normally.)
Federal income tax is withheld based on your W-4, filing status, and the IRS tables. For tax year 2026 the federal standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household. Federal tax uses seven brackets from 10% to 37%.
Every employee pays 6.2% Social Security tax on wages up to the 2026 wage base of $184,500, and 1.45% Medicare tax on all wages. Your employer matches both. High earners pay an extra 0.9% Medicare surtax on wages above $200,000 (single) or $250,000 (married filing jointly). FICA is federal and entirely separate from California SDI.
California's median household income is $100,149 according to the U.S. Census Bureau. A single filer earning around the California median takes home roughly $72,000–$75,000 per year after federal tax, California income tax, SDI, and FICA — before any pre-tax benefits, which push take-home higher.
California has the highest top income tax rate in the country and a mandatory SDI contribution, so high earners keep less here than almost anywhere. Middle earners are affected far less, and California's lack of any local income tax is a meaningful offset.
