California Paycheck Calculator

About the California paycheck calculator

Use this California paycheck calculator to estimate net pay after federal withholding, FICA, California state income tax, and State Disability Insurance. It is built for educational estimates so users can compare gross wages to a more realistic take-home amount.

California payroll can feel more complex than in many other states because withholding may include progressive state tax brackets, SDI, and special supplemental wage rules for bonuses and similar compensation.

How California paycheck withholding works

A California paycheck usually begins with gross wages. Payroll then subtracts eligible pre-tax deductions, applies federal income tax, Social Security, Medicare, California state income tax, and SDI, and finally subtracts any post-tax deductions.

That means two workers with the same salary can still have very different net pay if they have different filing status, 401(k) contributions, health benefits, or extra withholding settings.

California tax details that affect net pay

California uses a progressive state income tax system, so withholding changes with income level and setup. This makes California paycheck estimates more sensitive to deductions and withholding choices than in flat-tax or no-tax states.

Many employees also notice SDI on their pay stub. That line item is one of the most important differences between California payroll and payroll in states without a similar employee-side deduction.

What can change your California take-home pay

The biggest variables are filing status, retirement contributions, HSA or FSA deductions, health insurance premiums, overtime, bonuses, and any extra withholding entered in payroll.

When users compare different paycheck scenarios, they should focus on California income tax, SDI, and pre-tax deductions because those are often the largest reasons take-home pay changes.

California state income tax structure (2026)

California has the most progressive state income tax in the country, with nine brackets ranging from 1% on the first ~$10,000 of taxable income to 12.3% on income above ~$700,000 (single).

An additional 1% Mental Health Services Tax applies to taxable income above $1 million, bringing the top marginal rate to 13.3%. Brackets are indexed annually for inflation by the Franchise Tax Board (FTB).

Most middle-income California workers ($60,000–$150,000 single) end up paying an effective state rate of 4%–7% after deductions.

California SDI: the line that surprises new residents

California State Disability Insurance (SDI) is withheld from every paycheck on top of state income tax. The rate is 1.1% as of 2024, and beginning in 2024 California removed the annual SDI wage cap entirely — meaning every dollar of wages is subject to SDI, with no upper limit.

SDI funds California's short-term disability and Paid Family Leave (PFL) programs. On a $100,000 salary, SDI alone takes $1,100 per year.

California withholding: Form DE 4

California uses Form DE 4 (Employee's Withholding Allowance Certificate) for state withholding, separate from the federal Form W-4. The DE 4 lets you claim a different filing status and number of allowances for California than for federal — useful if you have significant California-source deductions or credits.

You can also add a flat extra dollar amount of California withholding per paycheck on the DE 4.

Example California paycheck at $75,000, single, biweekly

A single filer earning $75,000 in California, paid biweekly with no pre-tax deductions, has gross pay of about $2,884.62 per period. Federal withholding runs roughly $300–$340, FICA is $220.67, California state withholding is roughly $130–$160, and SDI is about $31.73 per period.

Estimated take-home pay lands near $2,135–$2,200 biweekly, or about $55,500–$57,200 annually. Adding a 6% 401(k) contribution (~$173 per period) lowers both federal and California taxable wages and typically returns about $35–$50 of that contribution as immediate tax savings.

What can change your California take-home pay

The biggest levers are pre-tax 401(k) and 403(b) contributions, HSA contributions, Section 125 health premiums, dependent-care FSA contributions, and your DE 4 entries. Bonuses are typically withheld at the federal supplemental rate (22%) plus California's 6.6% supplemental rate for most bonuses (10.23% for stock options and bonus payments above certain thresholds), plus FICA and SDI — meaning a California bonus often shows roughly 35%–45% withheld in a single check.

California paycheck — methodology and sources

Tax structure: California uses progressive state income tax brackets, so the marginal rate increases with taxable income. State withholding is applied on top of federal withholding and FICA.

FICA: 6.2% Social Security up to the annual wage base, plus 1.45% Medicare on all wages (with an extra 0.9% above $200,000 for single filers). Pre-tax deductions like traditional 401(k), HSA, and most health-insurance premiums lower the wages subject to federal (and usually state) income tax.

Local taxes (city, county, or school district) can apply in some areas and are not always reflected in a single statewide rate. For the most accurate withholding, verify against current guidance from the IRS (Publication 15-T) and the relevant California state tax agency.
