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.
LLC taxed as S-Corp in California
A California LLC that elects S-Corp treatment for federal tax purposes still needs a California-specific review. The rough federal comparison may move from default LLC self-employment tax treatment to shareholder-employee salary, payroll tax, and distribution assumptions, but that does not remove the need to check California entity-level taxes, fees, filings, payroll accounts, and timing rules.
For planning, separate the questions. First, use the calculator to test the federal salary and payroll tax assumption. Then ask how California treats the entity for annual tax, LLC fee, S-Corp tax, minimum franchise tax, Form 568 or Form 100S filing requirements, and payroll registration. Rules and exceptions can vary by year and fact pattern.
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
| Issue | Default LLC | S-Corp treatment |
|---|---|---|
| California entity-level minimum | $800 annual tax for many LLCs organized, registered, or doing business in California. | $800 minimum franchise tax for many California S corporations. |
| 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%. |
| Federal self-employment / payroll comparison | Default single-member LLC treatment commonly resembles sole proprietor self-employment tax treatment. | Salary is generally subject to payroll taxes; remaining profit may be distributed differently. |
| 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.
California S-Corp tax calculator assumptions
A California S-Corp tax calculator should not stop at federal payroll tax. For a rough planning estimate, separate the federal salary and payroll tax inputs from California-specific items that may belong in the admin cost assumption.
| Input or cost | Where it fits | California note |
|---|---|---|
| Net business profit | Main calculator profit input. | Different from California LLC total income for fee purposes. |
| Reasonable salary | Main calculator salary input. | Salary support still depends on duties, time, experience, and comparable pay. |
| California S-Corp 1.5% tax | Usually treated as a separate state cost in planning. | Check current FTB rules and how California source income applies. |
| $800 minimum or annual tax | Often part of the admin cost assumption. | Rules, timing, and exceptions vary by entity and year. |
| Payroll and filing costs | Admin cost assumption. | California payroll, bookkeeping, and return preparation can affect break-even. |
Questions to ask before changing anything

- 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?
