California, specifically
What makes California different.
California has the widest bracket spread in the country: 1% at the bottom and 12.3% at the top, plus the 1% Mental Health Services Tax on income over $1 million, which makes the effective top rate 13.3%. One relief compared with New York: no California city charges its own income tax, so the state return is the whole job.
- Nine brackets for 2026, 1% to 12.3%; the 1% surcharge over $1 million takes the true top rate to 13.3%.
- No city or county income taxes anywhere in California; the state return covers everything.
- Self-employment income is taxed as ordinary income; California has no special small business rate.
- The bracket thresholds are indexed, so the same income can land in a slightly cheaper bracket than last year.
Worked example: $160,000 net income, single filer.
Same caveat as the $110,000 example: credits, dependents, retirement contributions, and QBI phaseouts move the real number. Both examples are computed from the verified 2026 brackets, not hand-written figures.
California tax FAQ
Common questions.
- Does California tax self employment income in 2026? Yes. California has a graduated income tax in 2026, from 1% up to 13.3%. That sits on top of federal self employment tax and federal income tax. Nine brackets for 2026, 1% to 12.3%; the 1% surcharge over $1 million takes the true top rate to 13.3%.
- How much should I set aside for taxes on $110,000 of net income in California? On $110,000 of net self employment income (single filer), the estimate is about $15,543 self employment tax, $9,162 federal income tax, and $5,946 California income tax: roughly $30,651 total, or about $7,663 per quarter (~27.86% effective). Adjust for your deductions and credits.
- Does Los Angeles or San Francisco add a city income tax? No. California cities do not levy income taxes. A self-employed vendor anywhere in the state files one state return and owes only the state brackets plus, above $1 million of income, the 1% surcharge.
- Is the 1% surcharge really on top of 12.3%? Yes. The Mental Health Services Tax adds 1% on taxable income over $1 million, which is how the top effective rate reaches 13.3%. Below the threshold it does not apply at all.
