How Much Tax Does California Take From Your Paycheck?

California pulls two state taxes from your paycheck: personal income tax at progressive rates from 1% to 13.3%, and State Disability Insurance at a flat 1.3% of your gross wages in 2026.¹² SDI is the same for everyone. The income tax portion depends on how much you make, your filing status, and the allowances you claim on your withholding form. For a middle-income single filer, California-specific deductions typically run somewhere in the 5% to 7% range of gross pay. That answers the question of how much tax California takes from your paycheck at a headline level; the rest is in the details below.

The Flat Piece: State Disability Insurance

Every California employee pays into SDI, which funds short-term disability benefits and Paid Family Leave. In 2026 the rate is 1.3% of all gross wages, with no ceiling.² Every dollar you earn is subject to it, whether your salary is $30,000 or $3 million. The wage cap that used to apply was repealed effective January 1, 2024.³

The rate itself changes year to year based on the fund’s needs. It was 1.1% in 2024, 1.2% in 2025, and 1.3% now.⁴ On a $75,000 salary, 1.3% works out to $975 a year, or about $37.50 per biweekly paycheck.

The Variable Piece: California Income Tax

California uses a progressive income tax with nine brackets for most filers, running from 1% on the lowest slice of taxable income to 12.3% on the highest.¹ Progressive means each rate applies only to the income within its bracket. If you earn $60,000, you aren’t taxed at 9.3% on the whole amount. Your first several thousand dollars are taxed at 1%, the next portion at 2%, and so on.

A 1% Mental Health Services Act surcharge applies to taxable income above $1,000,000, pushing the effective top rate to 13.3% for the highest earners.⁵ Below that threshold, 12.3% is the ceiling.

The dollar cutoffs for each bracket are adjusted every year for inflation using the California Consumer Price Index, so the exact ranges shift.⁶ The thresholds also vary by filing status: married couples filing jointly get wider brackets than single filers, so more of their combined income stays taxed at lower rates. The Franchise Tax Board posts updated schedules each year.

One thing that trips people up is that the rates apply to taxable income, not gross pay. California allows a standard deduction, adjusted annually for inflation and roughly double for joint filers, which comes off before the rates hit. Itemizing is possible on the state return if you itemize federally, though the allowed deductions differ.

A Rough Walkthrough for an $80,000 Single Filer

The bracket thresholds shift each year, so treat this as illustrative rather than exact.

Start with gross pay. On a biweekly schedule, $80,000 ÷ 26 comes to about $3,077 per paycheck.
Subtract SDI at 1.3%. That’s roughly $40 per check.²
Calculate PIT withholding. Your employer looks up the amount using the tables in the California Employer’s Guide (DE 44), matching your gross pay against your filing status and allowances. For an $80,000 salary, the effective state income tax rate typically lands in the 4% to 5% range after the standard deduction and progressive brackets, or roughly $150 to $190 per biweekly check.⁷
What remains is your California net pay before federal taxes. In this example, California-specific deductions total around $190 to $230 per biweekly check, or roughly $4,900 to $6,000 a year.

The FTB publishes an online tax calculator that estimates annual liability based on your specific income and filing status.

How Bonuses and Other Supplemental Pay Get Hit

Bonuses, stock option income, commissions, overtime, and severance are treated as “supplemental wages” and withheld at flat rates instead of running through the bracket tables. Bonuses and stock options are withheld at 10.23%. Other supplemental pay, including overtime, commissions, and severance, is withheld at 6.6%.⁷

These flat rates are withholding estimates, not the final tax. When you file your return, everything is combined and taxed at your actual marginal rate. Too much withheld comes back as a refund. Too little means you’ll owe. The 10.23% figure catches attention because it looks steep next to a regular paycheck, but it’s a pre-payment, not a separate tax.

What You Can Control: Form DE 4

Your employer sizes your state income tax withholding using Form DE 4, the Employee’s Withholding Allowance Certificate.⁸ It’s California-specific and separate from the federal W-4. Filling out one doesn’t cover the other.

On the DE 4 you pick a filing status and claim withholding allowances. Each allowance shields a portion of your income from withholding, so more allowances mean less tax pulled from each paycheck and fewer mean more. You can also add a flat dollar amount to be withheld per pay period, which is useful if you have side income or want to avoid owing at tax time.

If you never submit a DE 4, your employer must withhold as if you’re single with zero allowances, the maximum-withholding scenario.² You’d usually get the excess back as a refund, but your cash flow takes the hit all year. Marriage, a new child, or a second job are good reasons to review the form.

What Doesn’t Come Out of Your Paycheck

Only PIT and SDI are pulled from your wages on the state side. California also imposes two payroll taxes on your employer that don’t reduce your take-home pay: Unemployment Insurance, at 1.5% to 6.2% on the first $7,000 of each employee’s annual wages depending on the employer’s claims history, and the Employment Training Tax, at 0.1% on the first $7,000.² If your pay stub shows only PIT and SDI as California deductions, that’s correct.

Federal withholding is a separate matter on top of the state deductions: Social Security at 6.2%, Medicare at 1.45%, and federal income tax.

If You Live Outside California but Work Here Some of the Time

Nonresidents owe California income tax on the portion of pay attributable to work physically performed in the state. The FTB uses a day-based ratio: California workdays divided by total workdays, multiplied by total compensation.⁹ Thirty out of 250 days in California means about 12% of your pay is California-source income.

Equity compensation is a separate trap. Even if you’ve moved out of California by the time stock vests, the state can still tax the portion that accrued while you were working here. Tech workers who leave and assume they’re finished with California tax often find out otherwise.
