At $100,000 gross income, a California single filer pays approximately $4,911 in state income tax — an effective rate of 4.9%. California has 10 progressive tax brackets from 1% to 13.3%, with the 9.3% bracket covering taxable income from $75,197 to $384,109 for single filers. The standard deduction is just $5,900 — far below the federal $16,100 — which pushes more income into higher brackets sooner.

Introduction
California has the highest state income tax rate in the United States: 13.3% on income above $1 million (12.3% regular rate plus a 1% Behavioral Health Services Tax, formerly the Mental Health Services Tax). But the rate that matters most for middle-to-upper earners is 9.3% — a broad bracket covering taxable income from $75,197 to $384,109 for single filers in 2026, where many households' marginal rate sits.
This guide covers California's income tax system in full: the exact 2026 bracket thresholds, how the low standard deduction makes California more expensive than the marginal rates suggest, the 1.3% SDI payroll deduction, how California taxes capital gains at ordinary rates (unlike federal), and how California compares to neighboring states for workers at different income levels.

Section 02
How Much Income Tax Do You Actually Pay in California?
Because California is a progressive system, your effective tax rate is always lower than your top marginal rate. The following figures are for single filers in 2026, after the $5,900 standard deduction and the $158 personal exemption credit (the credit phases out at higher incomes and is $0 in the $500,000 and $1,000,000 examples). Add 1.3% SDI on top of these figures for total state payroll deductions.
$50,000 gross income: Taxable income ~$44,100. California income tax: ~$973. Effective rate: ~1.9%.
$75,000 gross income: Taxable income ~$69,100. California income tax: ~$2,665. Effective rate: ~3.6%.
$100,000 gross income: Taxable income ~$94,100. California income tax: ~$4,911. Effective rate: ~4.9%.
$150,000 gross income: Taxable income ~$144,100. California income tax: ~$9,561. Effective rate: ~6.4%.
$250,000 gross income: Taxable income ~$244,100. California income tax: ~$18,861. Effective rate: ~7.5%.
$500,000 gross income: Taxable income ~$494,100. California income tax: ~$43,700. Effective rate: ~8.7%.
$1,000,000 gross income: Taxable income ~$994,100. California income tax: ~$102,459. Effective rate: ~10.2%.
The 9.3% bracket is where many middle-to-upper income Californians land at the margin. Once your taxable income crosses $75,197 (roughly $81,100 gross for a single filer after the standard deduction), you enter the 9.3% bracket and stay there until $384,109. Only the income above $75,197 is taxed at 9.3%.
Married Filing Jointly: What You Actually Pay
For married couples filing jointly, the $11,800 standard deduction and doubled bracket thresholds change the numbers meaningfully. Figures below include the ~$316 MFJ personal exemption credit:
$100,000 gross income (MFJ): Taxable income ~$88,200. California income tax: ~$1,946. Effective rate: ~1.9%.
$150,000 gross income (MFJ): Taxable income ~$138,200. California income tax: ~$5,330. Effective rate: ~3.6%.
$250,000 gross income (MFJ): Taxable income ~$238,200. California income tax: ~$14,472. Effective rate: ~5.8%.
$500,000 gross income (MFJ): Taxable income ~$488,200. California income tax: ~$37,722. Effective rate: ~7.5%.
The MFJ 9.3% bracket starts at $150,394 of taxable income and runs to $768,218 — a much wider window than the single-filer bracket, which benefits dual-income households significantly.
Section 03
California vs Federal: The Standard Deduction Gap
One of the most significant and least discussed features of California income tax is how little the standard deduction reduces your taxable income compared to the federal system.
2026 standard deductions compared:
Federal (single): $16,100
California (single): $5,900
Difference: $10,200 — at 9.3%, this gap alone costs a single Californian in the 9.3% bracket approximately $949/year more in state tax than they'd pay if California matched the federal deduction.
California did not conform to the Tax Cuts and Jobs Act's increase in the federal standard deduction (enacted 2018). California's standard deduction has barely moved in decades and remains one of the lowest of any state. This means California residents have more of their income exposed to the progressive bracket system, even at moderate income levels.
Consequence: itemizing is more attractive on the California return than the federal one for many filers. California allows full deduction of mortgage interest (no TCJA limitation), state property taxes, and charitable contributions — without the federal SALT cap. For homeowners with large mortgages, itemizing on the California return can significantly reduce taxable income below what the standard deduction provides.
California also offers its own personal exemption credit: $158 for single filers and $316 for married filing jointly in 2026 (adjusted annually). Note: this is a tax credit (directly reduces tax owed) rather than a deduction (which reduces taxable income).
Section 04
SDI and Total California Payroll Deductions
California's income tax is not the only state-level deduction taken from a paycheck. California State Disability Insurance (SDI, officially CASDI) adds a meaningful additional cost.
SDI 2026 rate: 1.3% of all wages — no annual cap.
Since 2024, California removed the SDI wage ceiling. Previously, SDI applied only up to a wage base (~$153,000); now it applies to 100% of wages regardless of income. This change significantly increased the SDI cost for higher earners.
What SDI costs at different income levels (1.3%, no cap):
$75,000 salary: $975/year SDI
$100,000 salary: $1,300/year SDI
$150,000 salary: $1,950/year SDI
$250,000 salary: $3,250/year SDI
$500,000 salary: $6,500/year SDI
$1,000,000 salary: $13,000/year SDI
What you get for SDI: California's SDI funds State Disability Insurance (70–90% wage replacement for new claims filed since 2025, for up to 52 weeks if you cannot work due to illness or injury) and California Paid Family Leave (PFL — up to 8 weeks paid at 70–90% for bonding or caregiving). Unemployment Insurance (UI) is a separate employer-paid tax.
Total state deductions at $100,000 salary (single filer):
California income tax: ~$4,911
SDI: $1,300
Total California state deductions: ~$6,211 (6.2% of gross)
No California city or county levies a personal income tax. The state rate plus SDI is the complete California state-level income deduction.
Section 05
Capital Gains Tax in California 2026
California taxes capital gains at the same rates as ordinary income — there is no preferential long-term capital gains rate at the state level. This is one of California's most significant tax differences for investors and tech workers with equity compensation.
California capital gains rates:
Short-term capital gains: taxed as ordinary income (1%–13.3%)
Long-term capital gains: also taxed as ordinary income (1%–13.3%) — no 0%/15%/20% preferential rate
This directly contrasts with the federal system, where long-term capital gains are taxed at 0%, 15%, or 20% depending on income. Take a California resident who sells stock with a $500,000 long-term gain that sits on top of other income already large enough to put the gain in the top federal 20% bracket and California's 11.3%–13.3% brackets. That sale faces:
Federal tax: 20% = $100,000 (plus 3.8% NIIT = $19,000, total federal $119,000)
California state tax: 11.3%–13.3% at 11.3% to 13.3% on the gain in that scenario (12.3% from $768,213; 13.3% above $1,000,000) — approximately $56,500–$66,500
Combined effective rate on the gain: approximately 35–37%
RSUs and stock options: California taxes RSU vesting and non-qualified stock option exercises as ordinary income at the same 1%–13.3% bracket rates. ISOs are not taxed at exercise for regular California tax purposes but create an AMT preference item. California's AMT rate is 7% on alternative minimum taxable income.
For this reason, California's capital gains treatment is a primary driver of the tech worker relocation trend — states like Nevada, Texas, and Florida charge $0 in state tax on the same capital gain.
Section 06
California Compared to Neighboring States
California's income tax is the highest in the United States. For workers considering relocation or remote-work residency changes, here is how California compares to the most common alternative states at $100,000 and $250,000 income.

At $100,000: A California worker pays approximately $4,911 more per year in state income tax than their Nevada or Texas equivalent. At $250,000, the differential reaches $18,861. Over a 10-year career at $250,000, the cumulative California income tax advantage for a Nevada resident could reach about $189,000 — before accounting for capital gains on equity.
Remote workers: California applies its income tax to income earned in California, even for remote workers. For nonresidents, California taxes only California-source income, and wages are sourced to where the services are performed — not where the employer is located. Remote workers who relocate must establish genuine non-California residency and avoid performing services in California to avoid California tax claims.
Section 07
Who Pays the Most (and Least) Under California's System
California's income tax system creates very different burdens depending on income type, lifestyle, and life stage.
Who pays the most:
High-income single workers with equity compensation: Tech workers vesting RSUs or exercising options at $500,000–$2M+ annual income face California rates of 10.3%–13.3% on top of federal rates — combined marginal rates that can approach or exceed 50% on ordinary income at the top. California's no-preferential-rate policy on capital gains amplifies this further.
Investors selling appreciated assets: No California long-term capital gains rate — all gains taxed as ordinary income at up to 13.3%. A $1M stock sale gain costs up to $133,000 in California tax alone.
Business owners in pass-through entities: S-corp and partnership income flows through to individual California returns at ordinary rates — no flat pass-through deduction equivalent to the federal Section 199A at the state level.
Who pays the least relative to income:
Retirees on Social Security: California does not tax Social Security benefits. Combined with lower ordinary income in retirement, retirees with mainly Social Security plus modest IRA withdrawals face relatively light California income tax.
Lower-income workers: The 1%–6% brackets at low income levels are relatively modest. The CalEITC (California Earned Income Tax Credit — up to $3,756 for tax year 2025) and Young Child Tax Credit (up to $1,189 per return for tax year 2025) can eliminate California income tax entirely for the lowest-income households.
Married couples with one earner: The MFJ bracket thresholds are exactly double the single thresholds (rare among states), providing marriage-neutral treatment. A dual-income couple each earning $75,000 ($150K combined) pays roughly the same California tax as a single-income family with $150K gross.

⚠ Not for simple single-state returns. Free filing is fine for straightforward W-2 situations.
California has 10 income tax brackets for 2026, running from 1% on income up to $11,456 (single) to 13.3% on income above $1,000,000. The 13.3% top rate is the highest state income tax rate in the US and consists of 12.3% regular tax plus a 1% Behavioral Health Services Tax (formerly the Mental Health Services Tax) on income above $1M. For many middle-to-upper earners the 9.3% bracket is the marginal rate.
Q
How much California income tax do I pay on $100,000?
A California single filer with $100,000 gross income pays approximately $4,911 in state income tax in 2026 — an effective rate of about 4.9%. Taxable income is reduced first by the $5,900 California standard deduction to approximately $94,100. Additional SDI of $1,300 (1.3%) brings total California state deductions to approximately $6,211. These are estimates; consult the California Tax Calculator for your specific situation.
Q
What is California's standard deduction for 2026?
California's standard deduction for 2026 is $5,900 for single filers and married filing separately, and $11,800 for married filing jointly or head of household. This is significantly lower than the 2026 federal standard deduction of $16,100 (single). California has not conformed to the higher federal standard deduction enacted in 2018. Because of this, itemizing is more attractive on the California return than on the federal return for many filers.
Q
Does California have a flat tax or progressive income tax?
California has a progressive income tax — not a flat tax. Tax rates increase as income rises, from 1% on the lowest bracket to 13.3% on income above $1 million. Only the income within each bracket is taxed at that bracket's rate. This means a Californian earning $100,000 does not pay 9.3% on all $100,000 — they pay 1% to 8% on the first $75,197 of taxable income, and 9.3% only on the amount above $75,197.
Q
Does California tax capital gains differently from income?
No — California taxes all capital gains (both short-term and long-term) at the same ordinary income rates of 1%–13.3%. There is no preferential long-term capital gains rate in California, unlike the federal system which taxes long-term gains at 0%, 15%, or 20%. This makes California especially expensive for investors, tech workers with equity vesting, and business owners selling appreciated assets.
Q
What is California SDI and how much does it cost?
California SDI (State Disability Insurance, CASDI) is a mandatory payroll deduction of 1.3% on all wages — with no annual wage cap since January 2024. On a $100,000 salary, SDI costs $1,300/year. SDI funds California's disability pay program (70–90% wage replacement for illness or injury, for claims filed since 2025) and Paid Family Leave (8 weeks at 70–90% for bonding or caregiving). SDI is employee-paid and deductible on your federal return as a state income tax (subject to the federal SALT limit).
Q
Does California tax Social Security income?
No — California does not tax Social Security benefits. Regardless of income level or filing status, Social Security retirement and disability income is completely exempt from California income tax. This is one of California's few retirement tax advantages. Federal tax on Social Security (up to 85% of benefits for higher-income retirees) still applies.
Q
What is the Mental Health Services Tax in California?
The Mental Health Services Tax (MHST, renamed the Behavioral Health Services Tax for tax years from 2025) is a 1% surcharge on California taxable income above $1,000,000. It applies to the portion of income above $1M only — not to all income. This is what pushes California's top rate from 12.3% to 13.3%. The MHST was enacted by Proposition 63 in 2004 and funds county mental health programs. It applies to individuals, not corporations.
Q
How does California income tax compare to Nevada?
Nevada has no state income tax — California residents pay California's full progressive rate (1%–13.3%) while Nevada residents pay $0 in state income tax. At $100,000, a California single filer pays approximately $4,911 in state income tax that a Nevada resident avoids. At $250,000, the California income tax bill is approximately $18,861 versus $0 in Nevada. For more detail, see the California vs Nevada Tax Comparison.
Q
Can I avoid California income tax by working remotely from another state?
Not automatically. California taxes nonresidents only on California-source income, and wages are sourced to where the work is physically performed, not where the employer is based. Moving your residence to Nevada or Texas while working for a California company does not by itself end California tax if you are still treated as a California resident or you perform services in California. To avoid California tax, you typically need genuine non-California residency AND to perform your services outside California. Consult a qualified California tax attorney before making relocation decisions.
Q
What are California's 2026 tax brackets for married filing jointly?
California's 2026 married filing jointly brackets run from 1% up to $22,912 to 13.3% above $1,536,426 — the bracket thresholds are exactly double the single-filer thresholds (the $1,000,000 Behavioral Health Services Tax threshold is the same for all filers). The wide 9.3% bracket covers $150,394 to $768,218 of taxable income. A couple earning $150,000 gross pays approximately $5,330 in California state tax after the $11,800 MFJ standard deduction — an effective rate near 3.6%.
