California stacks a progressive state income tax with SDI withholding on top of federal tax and FICA. See exactly what that looks like on your own numbers.
Why a California Paycheck Looks Different
Search "paycheck calculator California" and you'll notice the withholding lines add up to more than a lot of other states, even at the same salary. Two things specific to California cause that: a progressive state income tax with a high top rate, and a separate payroll withholding most states don't have at all, State Disability Insurance.
California State Income Tax Brackets
California's Franchise Tax Board (FTB) had not yet published the 2026 dollar bracket thresholds as of this writing. FTB's own 2026 Form 540-ES instructions tell taxpayers computing 2026 estimated tax to use the 2026 standard deduction together with the 2025 bracket thresholds, since the 2026 thresholds aren't out yet. This calculator follows that same instruction, using the 2025 thresholds with a note that they'll update once FTB publishes the real 2026 numbers. The rate ladder itself is set by statute and does not change year to year:
| 2025 CA taxable income (single/MFS), used as the 2026 stand-in per FTB | Rate |
|---|---|
| $0 – $11,079 | 1.0% |
| $11,079 – $26,264 | 2.0% |
| $26,264 – $41,452 | 4.0% |
| $41,452 – $57,542 | 6.0% |
| $57,542 – $72,724 | 8.0% |
| $72,724 – $371,479 | 9.3% |
| $371,479 – $445,771 | 10.3% |
| $445,771 – $742,953 | 11.3% |
| Over $742,953 | 12.3% |
Plus an extra 1% Behavioral Health Services Tax on income over $1,000,000, a fixed threshold that doesn't move with inflation. Source: California FTB, 2025 Tax Rate Schedules and the 2026 Form 540-ES instructions.
SDI: The Withholding Most States Don't Have
On top of income tax, California withholds State Disability Insurance at 1.3% of every dollar of wages, no cap. SDI funds California's short-term disability and Paid Family Leave benefits, meaning it isn't purely a tax with nothing back, it's what funds the program you'd draw from if you needed disability or family leave benefits.

Federal Tax and FICA Apply the Same as Anywhere
Underneath the California-specific lines, federal withholding (annualized method, 2026 single-filer brackets, $16,100 standard deduction) and FICA (6.2% Social Security up to the $184,500 wage base, 1.45% Medicare, no cap) work exactly the way they do in every other state. See our general paycheck calculator for the full federal bracket table and FICA detail.
A Worked Example
Say you earn $85,000 a year, paid biweekly: $3,269.23 gross per paycheck. Annualized, that's $85,000. Federal tax (after the $16,100 standard deduction, on $68,900 taxable): $9,870 a year, or $379.62 a paycheck. FICA: Social Security $5,270.00/year ($202.69/paycheck); Medicare $1,232.50/year ($47.40/paycheck). California state income tax on $85,000, using the bracket table above: $4,343.64 a year, or $167.06 a paycheck. SDI: $85,000 × 1.3% = $1,105.00 a year, or $42.50 a paycheck. Net pay: $3,269.23 − $379.62 − $202.69 − $47.40 − $167.06 − $42.50 = $2,429.96 take-home per paycheck. The same $85,000 salary with no state tax at all would net $2,639.52 per paycheck, a difference of $209.56 every two weeks, or roughly $5,449 a year, entirely attributable to California's state income tax and SDI.
What This Estimate Leaves Out
This calculator applies California's brackets directly to gross wages, without subtracting a separate California standard deduction first, and without modeling pre-tax deductions like a 401(k) or health insurance premium. Both would lower your real withholding a bit below what's shown here. And since the 2026 bracket thresholds aren't published yet, this uses 2025's, per FTB's own current guidance, not a final 2026 number. Once FTB publishes the actual 2026 schedule, this page updates to match.
Frequently Asked Questions
Why does California take out so much more than other states?
Two reasons stack on the same paycheck: California has one of the highest top marginal state income tax rates in the country (up to 12.3%, plus an extra 1% surcharge on income over $1,000,000), and it separately withholds State Disability Insurance (SDI) at 1.3% of every dollar of wages, with no cap. Most states have neither of those at California's level.
What is SDI on my California pay stub?
State Disability Insurance, a payroll tax that funds California's short-term disability and Paid Family Leave programs. It's withheld automatically at 1.3% of your wages, with no wage cap as of 2024 and continuing in 2026, so it applies to every dollar you earn, not just income up to some threshold.
Are California's 2026 tax brackets final?
Not yet published as of this writing. California's Franchise Tax Board (FTB) inflation-adjusts its bracket dollar thresholds every year but had not released the 2026 thresholds at the time this page was built. FTB's own 2026 estimated-tax instructions tell taxpayers to use the 2025 bracket thresholds as a stand-in until the 2026 ones are published, which is exactly what this calculator does, with this note attached so it's never presented as more final than it is.
Does this calculator account for California's standard deduction?
This calculator applies California's tax brackets directly to your gross pay, without subtracting a separate California standard deduction first, the same simplified approach used for New York and New York City on this site. That means the California and SDI figures shown will run a little higher than your exact real withholding, which is disclosed here rather than hidden.
What is the 1% surcharge over $1,000,000?
California's Behavioral Health Services Tax (formerly the Mental Health Services Tax), an additional 1% on income over $1,000,000 in a year, on top of the regular bracket rate. It only affects very high earners and won't show up on most paychecks.
Is California take-home pay always lower than a no-tax state at the same salary?
At the same gross salary, yes, more will be withheld in California than in a state with no income tax, because of both the state income tax brackets and SDI. Whether that's offset by pay scales, which tend to run higher in California for many roles, isn't something a paycheck calculator can answer; it only shows the withholding math.
Is this tax or legal advice?
No. It's an educational estimation tool. Confirm your actual withholding with your pay stub or a licensed tax professional, especially given the pending 2026 bracket update noted above.
