Federal + self-employment + California state income tax.
Does California tax 1099 income?
California is modeled with its audited 2026 individual income-tax path in addition to federal income tax and self-employment tax.
For a California 1099 worker, the state component can change the total reserve compared with a no-income-tax state. The calculator keeps California tax separate so you can see how much of the estimate comes from the state layer rather than treating everything as one percentage.
If you are comparing a California W-2 job with a contractor offer, calculate the tax bill here first and then use the California W-2 vs 1099 page for the compensation decision.
California 1099 tax examples by income
The table below is calculated from the same production engine as the calculator above. It uses a single-filer baseline with no business expenses, no health-insurance deduction, no retirement contribution, no W-2 wages, no withholding and no estimated payments. Your personalized result above is more useful than these examples.

How the California 1099 estimate is built
1. Start with net business profit
1099 forms report payments, but tax planning usually needs business profit. The calculator subtracts the business expenses you enter from gross 1099 revenue before the self-employment calculation. This is why two contractors with the same gross receipts can get different tax estimates.
2. Calculate self-employment tax separately
Self-employment tax is the Social Security and Medicare component generated by self-employment earnings. It is not the same as federal income tax and it does not disappear just because California has its own state individual income-tax calculation.
3. Calculate federal income tax
The federal layer uses the documented 2026 single-filer schedule, standard deduction and the site's QBI model. A deductible self-employed retirement contribution can reduce modeled AGI and QBI without reducing the Schedule C profit used for self-employment tax.
4. Add the California individual-income-tax layer
For a California 1099 worker, the state component can change the total reserve compared with a no-income-tax state. The calculator keeps California tax separate so you can see how much of the estimate comes from the state layer rather than treating everything as one percentage. The state amount is shown as a separate result rather than hidden inside a blended percentage.
What this California calculator does not include
Local business taxes, sales/use tax, payroll obligations, entity-level taxes and specialized credits are outside this calculator. The standard page is a resident single-filer planning estimate.
It also does not prepare a tax return, determine worker classification, model every credit or itemized deduction, or reproduce every special state exception. If your situation involves multiple businesses, an S corporation, partnership income, local taxes or complex credits, use the result as a planning baseline and confirm the details with the official forms or a qualified tax professional.

What to do after you calculate the tax bill
A tax bill estimate answers “how much tax does this scenario generate?” It does not automatically answer how much cash is still unfunded or when to send a payment. Use the set-aside calculator to turn your result into a reserve percentage, then use the quarterly calculator if you need a federal estimated-payment target.
California 1099 tax calculator FAQ
How much should I save for 1099 taxes in California?
There is no universal percentage. Use the calculator above for the tax bill, then open the set-aside calculator to account for withholding and payments already made and convert the remaining amount into a practical percentage of gross 1099 revenue.
Is self-employment tax the same as California state tax?
No. Self-employment tax is the federal Social Security and Medicare component. California state individual income tax is a separate line in this calculator.
Do business expenses reduce 1099 taxes in California?
Eligible business expenses reduce the modeled Schedule C-style profit. That can change self-employment tax, federal income tax and, depending on the state starting-income rules, the state estimate. Enter realistic expenses rather than assuming all gross receipts are profit.
Can I use this page if I also have a W-2 job?
Use the full 1099 tax calculator instead. W-2 wages affect federal progressive tax, Social Security wage-base coordination and withholding, so a pure 1099 state page is not the best model for a mixed-income situation.
