How California taxes a paycheck
California's schedule runs from 1% to 12.3% across nine brackets, plus a 1% mental health services tax on taxable income over $1 million that makes the effective top rate 13.3%. The brackets are indexed each year; for a single filer the 9.3% rate begins at $72,724 of taxable income, which is where most full-time salaries land. The standard deduction is small, $5,540 single and $11,080 married, and the personal exemption is a $153 credit per person rather than a deduction.
The second California line on every paycheck is State Disability Insurance. SDI is 1.3% of wages in 2026 and, since Senate Bill 951 took effect in 2024, there is no wage ceiling: a $300,000 earner pays 1.3% on all of it. The calculator shows SDI as its own line because it is a real, mandatory deduction that most paycheck calculators leave out. Combined with the 12.3% top bracket it takes California's effective top marginal rate on wages to 14.6%.
Bracket widths shown are the 2025 inflation-adjusted figures; the Franchise Tax Board publishes 2026 widths in the autumn, and they move up by a few percent. The exemption credits phase out above $252,203 of AGI for single filers, which is not modelled.
How much taxes are taken out of paychecks in California?
On a $60,000 salary in 2026, a single filer in California pays about $5,020 in federal income tax, $4,590 in Social Security and Medicare, about $1,650 in California income tax and $780 in SDI, leaving roughly $47,960 a year or $1,845 every two weeks. The state and SDI together take about 4% of gross pay at this level.
The picture changes above $72,724 of taxable income, where the 9.3% bracket begins. At $150,000 a single filer's California tax is about $9,720 plus $1,950 of SDI, an effective state rate close to 8%. No California city or county taxes wages; San Francisco's payroll tax is levied on employers.
California compared with its neighbours
California borders Oregon, Nevada and Arizona, and they could hardly be more different. Nevada taxes no wages. Arizona is a flat 2.5%. Oregon reaches 8.75% at $11,400 of taxable income and 9.9% at $125,000, but has no sales tax and lets filers deduct up to about $8,250 of federal tax. On a $60,000 single salary the state tax is roughly $1,650 in California, $3,980 in Oregon, $1,290 in Arizona and $0 in Nevada.
That ordering, with Oregon above California at ordinary salaries, surprises people. California's low bottom brackets shelter the first $72,724 at 6% or less; Oregon's schedule gets to 8.75% almost immediately. California overtakes Oregon only above about $500,000, where its 11.3% and 12.3% brackets and unlimited SDI apply.
Withholding forms and filing status in California
California employers withhold from Form DE 4, which uses allowances and its own tables; an employee who files only the federal W-4 is withheld using its status and no additional allowances. California's married brackets are exactly double the single ones, so two earners on similar salaries pay about the same jointly as separately, while a couple with one earner benefits from the doubled thresholds. Head-of-household filers have a separate, wider schedule that this estimate does not use.
California has no reciprocal agreements with any state and taxes non-residents on California-source wages, including days worked in the state by residents of Nevada, Arizona or Oregon. The state's residency rules are audited closely for high earners who move to Nevada or Texas; wages earned while still a California resident remain taxable there whatever the later address.
