LLC vs S-Corp in California
California adds state-level costs and rules that can materially change an LLC vs S-Corp estimate. Use this guide as a starting point, not as tax advice.
Short answer
In California, the LLC vs S-Corp question is not only about federal self-employment tax. California LLCs commonly face an $800 annual tax and may owe an LLC fee based on California total income. California S corporations commonly face an $800 minimum franchise tax and a 1.5% tax on California source income.
That means a California S-Corp estimate should include both the federal payroll/self-employment tax comparison and California-specific entity costs before you discuss the result with a qualified tax professional.
California LLC costs to understand
The California Franchise Tax Board says LLCs that are organized, registered, or doing business in California generally must pay the $800 annual tax. LLCs may also owe an annual LLC fee when total California income reaches $250,000 or more.
| California total income | LLC fee |
|---|---|
| $250,000 - $499,999 | $900 |
| $500,000 - $999,999 | $2,500 |
| $1,000,000 - $4,999,999 | $6,000 |
| $5,000,000 or more | $11,790 |
This fee is based on California total income for LLC fee purposes, not just the owner's net profit. For some e-commerce or high-revenue businesses, that distinction can matter.
California S-Corp costs to understand
The FTB says California S corporations with California source income are taxed at 1.5%. California S corporations are also subject to the $800 minimum franchise tax, with rules and exceptions such as first-year treatment that should be checked against current FTB guidance.
A California S-Corp can also add payroll setup, payroll filings, reasonable compensation support, a California S Corporation Franchise or Income Tax Return, bookkeeping, and separate records.
California LLC vs S-Corp comparison

| Additional California entity tax or fee | LLC fee may apply when California total income reaches $250,000 or more. | California taxes S corporations with California source income at 1.5%. |

| Admin complexity | Often simpler for a single-owner business, though California Form 568 and fees may apply. | Adds payroll, reasonable compensation, Form 100S, separate records, and more tax coordination. |
How to use the SCorpMath calculator for California
Start with the S-Corp tax savings calculator. Enter your expected annual net profit, estimated reasonable salary, filing status, and other W-2 wages if relevant. For the admin cost field, include a California-aware estimate for payroll, bookkeeping, business tax return preparation, state filings, and entity-level taxes or fees you expect to apply.
The calculator does not automatically calculate California's S-Corp 1.5% tax, LLC fee, California personal income tax, local taxes, or state payroll rules. Treat California costs as part of the admin cost assumption and review the result with a qualified professional.
Questions to ask before changing anything
- Would the entity be eligible for S-Corp treatment?
- What salary could be supportable for the work the owner performs?
- How would California's 1.5% S-Corp tax affect the estimate?
- Would the California LLC fee apply based on total California income?
- What payroll, bookkeeping, and tax filing costs would be added?
- Does Form 2553 timing or state treatment create a deadline issue?
