California Paycheck Calculator

Paycheck taxes in California

California runs the nation's most graduated income tax, with nine brackets climbing from 1% to 12.3% of taxable income. An additional 1% mental-health surcharge applies to income over $1 million, pushing the true top rate to 13.3% — the highest in the nation — though that surcharge is not modeled here. The standard deduction is small ($5,706 single / $11,412 married filing jointly), so most of a paycheck is exposed to the bracket schedule.

Bonuses and supplemental wages in California

Bonuses and other supplemental wages are frequently withheld differently from regular pay, and states set their own rules. This calculator applies California's regular withholding to every dollar and does not model a separate supplemental rate, so a bonus paycheck can come out higher or lower than the figure above. Federal supplemental withholding is a flat 22% up to $1 million; for California's own treatment, check the state authority linked below.

For the federal half, which this site does model, compare what withholding takes from a bonus against what you actually owe — the 22% flat rate is withholding, not a tax bill, and the difference comes back at filing.

California vs. its neighbors

On a $100,000 salary you keep $73,972 in California — $5,208 less than in neighboring Nevada, $3,102 less than in Arizona, and $2,969 more than in Oregon.

Federal income tax and FICA are identical in every state, so the whole gap above is state income tax. Single filer, $100,000 of wages, no 401(k) or other pre-tax deductions, 2025 state tables. Local income taxes (city and county) are not included. Run your own salary through the calculator above, or on any state's page.

Neighbours are only part of the picture. The study behind these figures ranks what a $100,000 salary takes home in all 50 states, with California's row in place — the entire spread between best and worst is state income tax, since federal tax and FICA are identical everywhere.

A worked example at California's median income

California's median household income is $100,600 (2024, U.S. Census Bureau via FRED (real median household income)). Run through the same engine as the calculator above (single filer, taxes only):

That is an effective all-in tax rate of 26.1% at the median — your own number depends on filing status, 401(k), and benefits. Enter your salary above for the exact figure.
