California vs its neighbors
The same $100,000 of 2026 profit for a single sole proprietor, run through each state's rules. Federal tax is the same everywhere, so the difference is state income tax. Against its neighbors, the same $100,000 of profit costs $2,325 more in Oregon and $4,254 less in Nevada.
| State | State income tax | Total tax | Set aside | vs California |
|---|---|---|---|---|

What's different about California for the self-employed
- California has not published its 2026 inflation-adjusted brackets yet; these are computed from the 2025 figures using the state's official 3.4% indexing factor and may differ by a few dollars.
- Every LLC, including single-member LLCs, owes the $800 annual minimum franchise tax even with no profit, plus an LLC fee starting at $900 once California income reaches $250,000. Sole proprietors without an LLC do not.
- California's estimated payments are due 30% in April, 40% in June, 0% in September, and 30% in January.
- Every LLC doing business or organized in California owes an $800 annual tax (Form FTB 3522) even with no business activity, until the LLC is cancelled; the first payment is due by the 15th day of the 4th month after filing with the Secretary of State. The first-year exemption applied only to tax years 2021-2023.
- LLCs with California total income over $250,000 also owe a separate LLC fee (starting at $900 for $250,000-$499,999), which must be estimated and paid by the 15th day of the 6th month of the tax year.
- Estimated tax is front-loaded: 30% is due April 15, 40% June 15, nothing for the September installment, and 30% January 15.
California estimated payments and deadlines
California collects its own estimated income tax with Form 540-ES, separately from the IRS. Required if you expect to owe at least $500 ($250 if married/RDP filing separately) in California tax for 2026 after withholding and credits, and your withholding and credits will be less than the smaller of 90% of your 2026 tax or 100% of your 2025 tax (110% if 2025 AGI was over $150,000).
| Installment | California due date | Share of the year | Federal due date |
|---|---|---|---|
| Q1 | April 15, 2026 | 30% | April 15, 2026 |
| Q2 | June 15, 2026 | 40% | June 15, 2026 |
| Q3 | September 15, 2026 | 0% | September 15, 2026 |
| Q4 | January 15, 2027 | 30% | January 15, 2027 |
The 2026 California income tax return is due April 15, 2027.

LLC fees and sales tax in California
- Forming an LLC: $70 state filing fee.
- Statement of Information: $20, every two years, due every two years, in a window set by your formation month.
- Sales tax: 7.25% statewide, plus local rates in many cities and counties. Use the Sales Tax Calculator to price a sale.
A single-member LLC is taxed exactly like a sole proprietorship unless it elects S or C corporation status, so the self-employment tax figures on this page apply either way.
