California Paycheck Calculator

No — California expressly prohibits cities and counties from levying a local personal income tax on wages (Revenue & Taxation Code §19005). This contrasts with New York City (3.876%), Philadelphia (3.75%), or San Francisco's 0.38% Payroll Expense Tax (which is levied on employers, not employees). As a California W-2 employee, your paycheck is subject to only state and federal taxes plus mandatory SDI — no municipal withholding will appear on your stub.

SDI (State Disability Insurance) is administered by the California Employment Development Department (EDD). It funds two distinct programs: (1) State Disability Insurance, which replaces up to 60–70% of wages if you are unable to work due to illness, injury, or pregnancy for up to 52 weeks; and (2) Paid Family Leave (PFL), providing up to 8 weeks of partial pay for bonding or caregiving. Through 2024, SDI was capped at a wage ceiling (~$153,164). SB 951 (signed 2022) removed the ceiling, effective 1 January 2024 — meaning from 2024 onward, the 1.2% rate applies to all earned wages with no annual cap.

Traditional (pre-tax) 401(k) contributions reduce both your federal and California state taxable income dollar-for-dollar. For example, contributing $500/month ($6,000/year) on an $85,000 salary lowers federal taxable income from $70,000 to $64,000 and CA taxable income from $79,460 to $73,460. However, pre-tax contributions do NOT reduce Social Security, Medicare, or CA SDI bases — these three taxes continue to apply to your full gross pay. Health Savings Account (HSA) contributions via payroll deduction follow the same federal-and-state dual exemption rule. Roth 401(k) contributions are post-tax and do not reduce any taxable base.

Texas and Florida have 0% state income tax and no state disability insurance. California levies progressive income tax (1%–13.3%) and 1.2% SDI with no wage ceiling. On an $85,000 salary in 2026, a California single filer pays approximately $3,681 in CA income tax and $1,020 in SDI annually — costs that simply don't exist in Texas or Florida. Additionally, California's standard deduction ($5,540 single) is far lower than the federal deduction ($15,000), meaning more income is exposed to the state's progressive brackets. The top California marginal rate of 13.3% applies to incomes over $1,000,000.

Your marginal rate is the rate applied to your last dollar of income — for example, 22% federal and 8.0% CA on a $95,000 annual income. Your effective rate is the blended average across all brackets on total income. Because progressive systems tax only the portion of income within each bracket, the effective rate is always lower than the marginal rate. For example, a $85,000 annual salary in California (single) results in roughly 18–20% total effective combined rate, even though the top marginal bracket is much higher.

The California Franchise Tax Board (FTB) permits two withholding methods for supplemental wages (bonuses, commissions, overtime above normal). (1) Flat Method: Withhold a flat 10.23% CA state tax (plus applicable federal rate, typically 22% flat or 37% if the bonus exceeds $1M). (2) Aggregate Method: Add the bonus to the most recent regular pay period and calculate tax on the combined amount. Most employers use the flat method for simplicity. Your employer's payroll system determines which is applied.
