CALIFORNIA PAYCHECK CALCULATOR

Top combined rate: 14.6% (13.3% income tax + 1.3% SDI)

California doesn’t just have the highest state income tax rate in the country at 13.3%, it also charges that on top of an uncapped 1.3% State Disability Insurance tax that never stops taking a bite, no matter how much you earn. Stack the two together and high earners in California face a combined 14.6% state-level marginal rate on wages, the steepest of any state. Most workers never see that top bracket, but the SDI tax touches every single paycheck, from a barista in Fresno to a software engineer in Palo Alto.

A California paycheck runs through five separate deductions: federal income tax, state income tax, SDI, Social Security, and Medicare. There’s no city or county income tax anywhere in the state, so those five lines are the whole picture. If you’re weighing California against a lower-tax neighbor, take a look at the Nevada paycheck calculator for a no-income-tax comparison, the Arizona paycheck calculator, the Oregon paycheck calculator, or the Texas paycheck calculator.

Every Deduction on a California Paycheck

• Federal income tax: Based on the 2026 IRS brackets, 10% to 37%, after the $16,100 single / $32,200 joint standard deduction.
• California state income tax: Nine brackets running from 1% to 12.3%, plus the extra 1% Mental Health Services Tax once taxable income crosses $1,000,000. California’s own standard deduction is much smaller than the federal one, just $5,706 for single filers.
• California SDI (State Disability Insurance): 1.3% of every dollar of wages, no cap. This is the line that makes California unusual, most states either don’t have this tax or stop collecting it once you hit a wage ceiling.
• Social Security: 6.2% of gross wages up to $184,500 for 2026.
• Medicare: 1.45% of all wages, no cap, plus an extra 0.9% on wages above $200,000 (single) or $250,000 (married filing jointly).
• What’s NOT on a California paycheck: no city or county income tax anywhere in the state, so those five lines above are the complete list.

Why This Calculator Still Runs on 2025 Brackets

Here’s something most paycheck sites don’t tell you straight: California’s official tax year 2026 bracket thresholds don’t exist yet. The Franchise Tax Board indexes its brackets, standard deduction, and credits to California’s own inflation measure every year, using the change in the California Consumer Price Index between the prior June and the June before that. That inflation factor for 2026 has been calculated at roughly 2.971%, but the FTB doesn’t publish the finished dollar thresholds until late in the year they apply to. So right now, the most recently confirmed, officially published numbers are still the tax year 2025 brackets, the ones used on returns filed in early 2026. This calculator uses those verified figures as the best available stand-in, and the practical difference for most paychecks will be small, a few dollars either way once the real 2026 numbers land.

California Income Tax Brackets (Single / Married Filing Separately, latest confirmed FTB schedule)

Taxable Income	Rate
$0 – $11,079	1%
$11,079 – $26,264	2%
$26,264 – $41,452	4%
$41,452 – $57,542	6%
$57,542 – $72,724	8%
$72,724 – $371,479	9.3%
$371,479 – $445,771	10.3%
$445,771 – $742,953	11.3%
$742,953 – $1,000,000	12.3%
Above $1,000,000	13.3% (includes the 1% Mental Health Services Tax)

Married couples filing jointly get roughly double these thresholds at every step, and heads of household get a bit more room at the lower brackets too. Notice how wide that 9.3% band is: for a single filer it runs from about $72,700 all the way to $371,479, which is why most of the real tax planning conversation in California happens around 9.3%, not the eye-catching 13.3% headline number.

California vs. Its Neighbors: $70,000, Single Filer

Here’s how California stacks up against three western states with very different approaches to state tax, all at $70,000 in gross salary for a single filer.

State	State Tax + SDI Owed	Est. Net Pay*
California	~$3,438	~$54,637
Nevada	$0 (no income tax)	~$58,075
Arizona	~$1,348	~$56,728
Oregon	~$5,600	~$52,475

*Net pay is after federal tax, state tax and payroll taxes (SDI where applicable), Social Security, and Medicare, before any pre-tax deductions. Oregon’s figure is built from its published bracket structure, which varies slightly across sources, so treat it as an estimate to confirm against the Oregon Department of Revenue before publishing.

California Tax Burden: The Full Picture

Tax Type	California	National Average
Top income tax rate	13.3% (14.6% with SDI on wages)	~5.0%
State + avg. local sales tax	8.99%	~7.5%
Effective property tax rate	0.70%	~0.99%
Estate / inheritance tax	None	Varies by state

The picture is more balanced than California’s tax reputation suggests. Property tax is actually below the national average, largely thanks to Proposition 13, which caps how fast a home’s assessed value can rise each year and limits the base rate to 1%. Someone who bought a home decades ago can be paying property tax on an assessed value far below what the house is worth today. Sales tax runs a bit above the national average too, and the state has no estate or inheritance tax at all. It’s really the income tax and SDI stack that does the heavy lifting for California’s high-tax reputation, not property tax.

California Is a Tough State for Stock Compensation

If your pay includes RSUs, stock options, or a big liquidity event, California treats that income like any other paycheck dollar. There’s no separate, lower rate for long-term capital gains the way federal tax offers, everything from wages to a stock sale gets taxed at the same progressive rates up to 13.3%. A big RSU vest that pushes a tech worker’s income past $1,000,000 for the year gets hit with the Mental Health Services Tax on top of the regular bracket. That’s one reason equity-heavy compensation packages in places like the Bay Area come with real state tax planning conversations, timing a sale or a move can matter more in California than it does almost anywhere else. On the flip side, Social Security income stays fully exempt from California tax no matter how large your other income is, so retirees drawing mostly on Social Security see a lighter state hit than working professionals do.

Federal Tax: A Worked Example

Take a single filer earning $70,000 in 2026. Subtract the federal standard deduction of $16,100, and taxable income comes to $53,900. Here’s how that runs through the brackets:

• 10% on the first $12,400 = $1,240
• 12% on $12,400 to $50,400 ($38,000) = $4,560
• 22% on $50,400 to $53,900 ($3,500) = $770

Total federal tax: $6,570, an effective rate of 9.4% on the full $70,000. That’s before California’s own bracket table adds roughly another $2,528 in state income tax and $910 in SDI on top, which is where the difference between a California paycheck and a no-tax-state paycheck really shows up.

Frequently Asked Questions

California’s tax code rewards patience with property but not with paychecks, the SDI change alone quietly reshaped what high earners see leave their pay stub each cycle. Anyone budgeting a new California job offer should run the actual numbers rather than eyeball a percentage, the gap between the headline 13.3% and what most people actually pay in the 9.3% band is wide enough to change a real decision.
