TL;DR
California has the highest top marginal income-tax rate in the US (13.3% with the mental health surtax), but the first $10,756 is taxed at only 1%. Median earners pay an effective state rate closer to 4-6% - the famous 13.3% only hits earners above $1M.
How California state income tax works (2026 overview)
California taxes residents on worldwide income and non-residents on California-source income. The Franchise Tax Board (FTB) administers personal income tax through Form 540 (resident) and Form 540NR (non-resident or part-year). Wage earners pay tax via payroll withholding using Form DE 4, the California state equivalent of the federal W-4.
The system is genuinely progressive: the bottom bracket of 1% applies only to the first $10,756 of taxable income for a single filer, and most working Californians earning $60,000-$120,000 fall in the 8%-9.3% marginal range. The headline 12.3% rate (and the 13.3% combined rate with the Mental Health Services Tax surcharge) only hits the top 1-2% of earners. The 1% Mental Health Services Tax (Proposition 63, 2004) funds county mental-health programs and is itemized separately on the 540 schedule.
California is one of the few states that does NOT conform to the federal $10,000 SALT cap when calculating its own taxable income - the state adds back the federal SALT deduction. California is also unusual in that it does not allow a deduction for federal income tax paid, taxes long-term capital gains at ordinary rates (no preferential rate), and imposes a separate 1.1% State Disability Insurance (SDI) on wages with no wage cap as of 2024.
California's standard deduction is modest by federal standards: $5,540 for single filers and $11,080 for married filing jointly (2025 figures, indexed annually). Many high earners itemize to claim mortgage interest, charitable contributions and state-allowed deductions like California Lottery losses (up to winnings).
California state income tax brackets (2025-2026, single filer)
California uses nine progressive brackets ranging from 1% on the first $10,756 of taxable income to 12.3% on income above $721,314. A 1% Mental Health Services Tax adds on top for income over $1 million, pushing the effective top marginal rate to 13.3%.
| Taxable income | Marginal rate |
|---|---|
| $0 to $10,756 | 1% |
| $10,756 to $25,499 | 2% |
| $25,499 to $40,245 | 4% |
| $40,245 to $55,866 | 6% |
| $55,866 to $70,606 | 8% |
| $70,606 to $360,659 | 9.3% |
| $360,659 to $432,787 | 10.3% |
| $432,787 to $721,314 | 11.3% |
| $721,314 and above | 12.3% |
Plus 1% Mental Health Services Tax on taxable income above $1,000,000. State Disability Insurance (SDI) is 1.1% with no wage cap as of 2024.
California take-home pay calculator
Enter your annual gross salary and filing status. The calculator runs federal 2026 brackets + California state rules + FICA in your browser - nothing leaves the page.
Estimate only. Uses 2026 IRS brackets and California state rules. Does not include local city tax, retirement deductions, or pre-tax health insurance.
California take-home examples at common salary levels (2026, single filer)
Here is what a single filer keeps after federal income tax, California state tax, and FICA at five common salary levels in 2026. All numbers assume only the standard deduction and no retirement contributions, health-insurance premiums, or state-specific credits - the simplest case.
| Gross salary | Federal tax | California state tax | FICA | Take-home | Effective rate |
|---|---|---|---|---|---|
| $50,000 | $3,968 | $1,245 | $3,825 | $40,962 | 18.1% |
| $75,000 | $8,253 | $3,017 | $5,738 | $57,992 | 22.7% |
| $100,000 | $13,753 | $5,327 | $7,650 | $73,270 | 26.7% |
| $150,000 | $25,442 | $9,977 | $11,475 | $103,105 | 31.3% |
| $250,000 | $52,886 | $19,277 | $14,543 | $163,293 | 34.7% |
FICA = 6.2% Social Security on the first $176,100 of wages plus 1.45% Medicare on all wages. Married-filing-jointly numbers are roughly 5-8% lower at every income level because the federal brackets are nearly twice as wide and federal standard deduction doubles.
How California compares to neighbors (Oregon, Nevada, Arizona)
Same scenario for every state: $75,000 gross annual salary, single filer, no other deductions, 2026 federal brackets, $15,000 standard deduction. The only difference is the state tax line.
| State | Effective state rate | State tax at $75k | Take-home after all taxes |
|---|---|---|---|
| California (this state) | 4.69% | $3,517 | $57,492 |
| Oregon | 8.27% | $6,202 | $54,807 |
| Nevada | 0% | $0 | $61,010 |
| Arizona | 2.50% | $1,875 | $59,134 |
Effective state rate = state income tax divided by gross income. Federal tax ($8,253) and FICA ($5,738) are identical across all states.
California tax-planning checklist for 2026
- Maximize pre-tax 401(k) and 403(b) contributions. California fully conforms to the federal pre-tax treatment, so every dollar contributed saves you 9.3% in state tax plus your federal marginal rate plus FICA on the first $176,100 of wages. At $150,000 income, that's roughly 41-44% total savings on each pre-tax dollar.
- Use a Health Savings Account if you have a high-deductible health plan. California is one of only TWO states (with New Jersey) that does NOT conform to federal HSA tax treatment. HSA contributions are still federally tax-free, but California taxes them as regular income and California taxes any growth and interest in the HSA each year - a significant downside compared to other states.
- Time RSU vests and option exercises carefully. California taxes RSUs as ordinary income at vesting and ISO/NSO option exercises at the spread. The 12.3% top rate (plus 1% MH surtax over $1M) can take a serious bite. Consider 10b5-1 plans for executives to spread vesting across multiple tax years.
- Claim the California Earned Income Tax Credit (CalEITC). Worth up to $3,529 in 2024 for working families with three or more qualifying children. Phases out around $30,950 AGI for filers with kids. Even single filers under $30k may qualify.
- File Form DE 4 with your employer if you have multiple jobs or significant non-wage income. The default federal W-4 doesn't account for California's state withholding correctly when you have side income.
- Watch the SDI cap removal (2024+). California's 1.1% State Disability Insurance has no wage cap as of 2024. A $1M earner pays $11,000 in SDI alone, on top of state income tax. There is no way to opt out of SDI for W-2 employees.
- Consider 529 contributions for state tax savings. California does not offer a state deduction for 529 contributions, but qualified withdrawals are state-tax-free. Compare carefully with non-resident plans before opening.
Frequently asked questions about California income tax
Does California have a state income tax?
Yes. California levies a progressive state income tax with nine brackets ranging from 1% on the first $10,756 of taxable income (single) to 12.3% on income above $721,314. A 1% Mental Health Services Tax adds on top of any taxable income above $1 million.
What is the highest tax bracket in California?
The statutory top bracket is 12.3% on taxable income above $721,314 for single filers. Adding the 1% Mental Health Services Tax on income above $1M brings the effective top marginal rate to 13.3% - the highest in the United States as of 2026.
What is the California standard deduction for 2026?
California's 2026 standard deduction is $5,540 for single and married-filing-separate filers and $11,080 for married-filing-jointly, qualifying widow(er), or head-of-household filers.
How is my take-home pay calculated in California?
Start with gross salary, subtract federal income tax (2026 IRS brackets, $15,000 single standard deduction), subtract California state income tax using the brackets above, subtract FICA (6.2% Social Security up to $176,100 + 1.45% Medicare on all wages) and subtract SDI (1.1%). The remainder is your take-home pay.
What is California's SDI (State Disability Insurance) rate?
California SDI is 1.1% of wages with no wage cap as of 2024 - the cap was removed by SB 951. SDI funds disability insurance and paid family leave benefits and is withheld from every paycheck.
How much state tax do I pay on $100,000 in California?
Approximately $5,500-$6,200 in California state income tax on a $100,000 salary, depending on your deductions. The effective state rate at $100k is around 5.5-6.2%, far below the 12.3% top marginal rate that grabs headlines.
Are California's tax brackets the same for single and married filers?
No. Married-filing-jointly brackets are roughly double the single brackets at every level. For example, the 9.3% bracket starts at $70,606 of taxable income for single filers but at $141,212 for married filing jointly.
Does California tax retirement income, Social Security and 401(k) withdrawals?
California does not tax Social Security benefits but does tax 401(k), IRA and pension distributions as ordinary income. Public employee pension income and most private pensions are fully taxable at California's regular bracket rates.
What is the difference between marginal and effective California tax rates?
Marginal rate = the rate applied to your last dollar of income (your bracket). Effective rate = total state tax divided by gross income. A single filer earning $100,000 has a 9.3% marginal rate but only a ~5.5% effective rate because the lower brackets tax earlier dollars at much less.
Do I have to file a California state tax return as a non-resident?
Yes if you earned California-source income (wages worked in CA, rental income from CA property, business income from CA customers, etc.). Non-residents file Form 540NR and pay California tax only on California-source income.
Key terms used on this page
- Marginal tax rate
- The tax rate applied to your last dollar of taxable income - your bracket. If you earn $90,000 in California and the rate that applies to your last dollar is 5.85%, your marginal rate is 5.85%, even though most of your income is taxed at lower rates.
- Effective tax rate
- Your total tax divided by your gross income, expressed as a percentage. Because lower brackets tax earlier dollars at lower rates, your effective rate is always less than your marginal rate in progressive states. In a flat-tax state, marginal and effective rates are usually very close (offset only by deductions and exemptions).
- Standard deduction
- A fixed amount you subtract from gross income before calculating tax. For 2026 federal returns, the standard deduction is $15,000 single, $30,000 married filing jointly, and $22,500 head of household. Many states (including California if it offers one) have separate state standard deductions at different amounts.
- FICA (Social Security + Medicare)
- The federal payroll tax that funds Social Security and Medicare. As an employee, you pay 6.2% Social Security on the first $176,100 of 2026 wages plus 1.45% Medicare on all wages. Self-employed earners pay both halves (15.3% total) but can deduct half on their federal return.
- Withholding
- The tax your employer takes out of each paycheck and remits to the IRS and your state on your behalf. Adjusted via the federal Form W-4 (federal) and your state's W-4 equivalent. Over-withholding produces a refund; under-withholding produces an April bill (and possibly a penalty).
- Filing status
- Single, Married Filing Jointly (MFJ), Married Filing Separately (MFS), Head of Household (HoH), or Qualifying Widow(er). Determines which bracket schedule applies and the size of your standard deduction. Most married couples should compare MFJ vs MFS each year - MFS is occasionally better when one spouse has high medical expenses or unreimbursed business losses.
- Tax credit vs deduction
- A deduction reduces your taxable income (saves you tax = deduction x marginal rate). A credit reduces your tax dollar-for-dollar (saves you tax = credit amount). A $1,000 credit is worth more than a $1,000 deduction at the same income level.
Methodology and sources
Federal brackets: The 2026 federal income tax brackets used by the calculator (10%, 12%, 22%, 24%, 32%, 35%, 37% with single thresholds of $11,600, $47,150, $100,525, $191,950, $243,700, $609,350) are from the IRS Revenue Procedure published for tax year 2026, adjusted from 2025 for inflation. The 2026 federal standard deduction is $15,000 single, $30,000 married filing jointly, and $22,500 head of household.
State rules: The California state tax brackets, standard deduction, and other state-specific rules used on this page are sourced from the official California Department of Revenue (or equivalent state authority) for tax year 2025-2026.
FICA: Social Security wage base of $176,100 for 2026 (taxed at 6.2%) and Medicare tax of 1.45% on all wages. The Additional Medicare Tax (0.9%) on wages above $200,000 single / $250,000 joint is NOT modeled in the calculator above - it applies to high earners and would shave a small amount off the displayed take-home at those levels.
What the calculator does NOT model:
- Local city, county, or school district income tax (relevant in OH, PA, MI, NY-NYC, MD, AL among others)
- Pre-tax 401(k), 403(b), 457(b), HSA, and FSA contributions (each would reduce both federal AND state taxable income)
- Pre-tax health, dental, and vision insurance premiums
- State-specific credits (EITC, dependent care, retirement income exclusion, etc.)
- Itemized deductions for taxpayers who itemize instead of taking the standard deduction
- The federal Additional Medicare Tax (0.9%) on high earners
- The federal Net Investment Income Tax (3.8%) on investment income for high earners
- Alternative Minimum Tax (AMT) at the federal or state level
