Assumptions
- California tax = EDD Method B annual computation: wages − standard deduction ($5,706 / $11,412) → 2026 annual rate table → minus $168.30 per allowance; zero if wages ≤ low-income exemption ($18,896 / $37,791).
- SDI = 1.3% of wages after Section 125, no cap. Federal and FICA as in the US paycheck calculator.
- Annualized estimate divided by pay periods; no credits, itemized deductions or supplemental-wage rules. Jurisdiction: California, 2026.
How it is calculated
- Federal tax, Social Security and Medicare exactly as in the US paycheck calculator (2026 IRS/SSA figures).
- CA taxable wages = gross − 401(k) − pre-tax benefits − CA standard deduction. If gross ≤ low-income exemption, CA tax = 0.
- CA tax = 2026 Method B annual rate table (1.1% … 14.63%) − $168.30 × allowances, not below zero.
- SDI = 1.3% × (gross − pre-tax benefits). Take-home = gross − deductions − all taxes ÷ pay periods.
Examples
| Case (2026, biweekly) | Federal | CA withholding | SDI | Take-home / year |
|---|---|---|---|---|
| $57,000 married, 4 allowances (EDD Example F) | $2,480 | $86.00 | $741 | $49,332.50 |
| $75,000 single, 1 allowance | $7,670 | $3,052.03 | $975 | $57,565.47 |
| $120,000 single, 1 allowance | $17,570 | $7,606.48 | $1,560 | $84,083.52 |
| $250,000 married, 2 allowances | $37,468 | $16,235.96 | $3,250 | $177,532.04 |
Common mistakes
- Withholding ≠ final tax. Your Form 540 uses the lower actual rates, the personal exemption credit and renter's or child credits, so most employees get a state refund.
- Bonuses are withheld at a flat 6.6% (10.23% for stock options) in California, plus 22% federal.
- Method A wage-bracket tables used by some employers give slightly different per-paycheck amounts; the annual total is the same.
FAQ
Why is California withholding higher than the tax brackets I see online?
California law requires employers to withhold at rates 10% higher than the actual tax rates (1.1% instead of 1%, 10.23% instead of 9.3%, and so on). The EDD Method B tables used here are the official withholding schedules, so this matches your paycheck; the difference comes back as a refund when you file Form 540, where the real rates, exemption credits and other deductions apply.
What is SDI and why has it no cap?
State Disability Insurance funds disability and Paid Family Leave benefits. The employee rate is 1.3% for 2026 (up from 1.2%), and since 2024 there is no taxable wage ceiling, so high earners pay 1.3% on all wages. It is deductible on your federal return if you itemize.
How do allowances on Form DE 4 work?
Each allowance is a $168.30 annual tax credit in the Method B computation, and married employees claiming two or more allowances get the $11,412 standard deduction instead of $5,706. Claiming more allowances lowers withholding but not your actual tax; if you under-withhold you may owe penalties.
Does this include local taxes or the Mental Health Services Tax?
California has no city income taxes. The 1% Mental Health Services Tax on taxable income over $1 million is reflected in the top withholding rates (13.53% and 14.63%). Federal tax uses the 2026 standard deduction and brackets without credits.
