Self-Employed Tax Calculator — California (2026)
Self-employed in California? Your tax bill has three layers that a W-2 employee never sees in full: 15.3% self-employment tax on 92.35% of net profit, federal income tax, and California state income tax. This calculator applies all three to your 2026 net profit and shows the quarterly amount you should be setting aside. California uses a progressive income tax with 9 brackets running from 1.00% up to 12.30%, applied after a state standard deduction of $5,363.

Self-employment tax vs California income tax
Self-employment tax is federal and identical in all 50 states: 12.4% Social Security up to $184,500 of net earnings plus 2.9% Medicare with no cap. Half of it is deductible against income tax, which is why the calculator subtracts it before applying brackets.
California then taxes essentially the same profit figure at 1.00%–12.30%. On $80,000 of net profit that adds roughly $2,979 to the bill.
California has no city-level income tax, but high sales tax (7.25%–10.75%) and SDI payroll deduction (1.1% on wages up to $153,164).
Deductions that matter for California freelancers
Net profit — not gross revenue — drives every number here. Ordinary and necessary business expenses reduce SE tax, federal tax, and California tax simultaneously: the 2026 standard mileage rate of $0.67/mile, home-office square footage, software, equipment, professional insurance, and the self-employed health insurance deduction.
Retirement plans go further. A SEP-IRA or solo 401(k) reduces income tax (though not SE tax) and is often the largest single deduction available to a profitable tech contractor in Los Angeles.
Working for yourself in California
California's economy leans on tech, entertainment, and aerospace, which shapes the contractor market around Los Angeles — and your fixed costs. With one-bedroom rent near $2,450, a freelancer needs meaningfully more gross revenue than an employee to reach the same lifestyle, because there is no employer paying half of FICA.
California has the highest top marginal state income tax in the US at 13.3% (including the 1% mental-health surtax above $1M).
Local and payroll taxes California adds on top
State Disability Insurance (SDI) of 1.2% is withheld from all wages with no wage cap — an extra line most other states do not have. That deduction sits outside the federal and state income tax lines, so build it into your own budget on top of the numbers above.
California has no city-level income tax, but high sales tax (7.25%–10.75%) and SDI payroll deduction (1.1% on wages up to $153,164).
Nobody withholds these for you when you are self-employed in California. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from California
California has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Los Angeles resident spending part of the year at a client site in Nevada may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your California tax bill
California charges a 7.25% state sales tax, homeowners pay an average effective property tax of 0.71% of market value, and the minimum wage in force during 2026 is $16.90 an hour.
District taxes lift combined rates to 10.75% in parts of Los Angeles County.
Income tax is only one part of a state's take. California recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. California exempts Social Security but fully taxes pensions, 401(k) and IRA withdrawals; early distributions face an additional 2.5% state penalty.
California vs Nevada on the same salary
On a $90,000 salary, a single filer keeps about $67,731 a year in California against roughly $72,145 in Nevada — a difference of $4,414, or $368 a month.
Effective combined rates are 24.7% in California and 19.8% in Nevada. Set that gap against living costs: index 142 here versus 102 there, with property tax at 0.71% and 0.55% respectively.
