If you run a Business-of-One in California, the LLC vs S Corp decision has a layer the federal comparison doesn’t cover. On top of federal taxes, California adds its own business-level taxes and a fee, and which ones you owe depends on how your LLC files its taxes. In addition, electing S Corp status brings separate state returns and state payroll. This guide builds on our full LLC vs S Corp breakdown, so it covers the federal basics briefly and then focuses on what’s different in California.
Below, you’ll see how those pieces fit together, what they could cost, and how they may change the math for your business.
The Federal Basics at a Glance
First, a quick refresher. An LLC (limited liability company) is a legal structure you form with the state. An S Corp, on the other hand, is a tax election you make with the IRS that changes how the IRS taxes your LLC. In other words, the LLC comes first, and the election layers on top of it.
| Single-member LLC (SMLLC) | LLC with S Corp election | |
|---|---|---|
| Tax on profit | All net earnings are subject to self-employment tax | Payroll taxes apply to your salary; you can take remaining profit as distributions not subject to payroll taxes |
| How you pay yourself | Owner draws, no payroll | A reasonable salary through formal payroll, plus distributions |
| Federal filing | You report business income on your personal tax return | The business files a separate S Corp business tax return, and you file your personal return |
| Often a fit when | You’re early-stage, still building profit, or have a high-earning W-2 role | You’ve been self-employed 1 to 2 years with consistent profit, generally over $80,000 |
Self-employment tax is the contribution self-employed people make toward Social Security and Medicare, and it covers both the employer and employee share. The rate is 15.3% of net earnings, although the Social Security portion stops at an annual wage base ($184,500 for 2026). Keep in mind that the IRS doesn’t set an income threshold for the S Corp election. Instead, the $80,000 guideline reflects where the added work often pays off.
What Changes in California
The federal comparison works the same in every state. However, California adds three business-level charges on top of it: two taxes and one fee. California calculates each one differently. One is a flat amount, one follows revenue, and one follows net income. As a result, the charges you owe depend on your LLC’s tax status.
| Charge | Who pays it | How California calculates it |
|---|---|---|
| LLC annual tax | SMLLCs | A flat $800 each year |
| LLC fee | SMLLCs with $250,000 or more in total California income | A tiered amount that follows revenue, not profit |
| S Corp franchise tax | LLCs with an S Corp election | The greater of an $800 minimum or 1.5% of California net income |
In short, an SMLLC may owe the LLC annual tax and the LLC fee. By contrast, an LLC with an S Corp election owes the S Corp franchise tax in place of both. All three also sit apart from the personal income tax you pay as the owner.
California follows your federal S Corp election
California piggybacks on the federal election. So when your LLC elects S Corp status with the IRS, California generally treats it as an S Corp for state purposes too, without a separate state election form. Because of this, the decision you make federally also determines which California charges and filings apply. For timing and paperwork, see S Corp Application Form (2553) and How to Convert an LLC to S Corp.
The $800 minimum applies to both structures
Every LLC that forms or does business in California owes the $800 LLC annual tax each year, even in a year with no income. That continues until you formally cancel the LLC. California also offered a first-year exemption for LLCs formed from 2021 through 2023. However, that exemption has expired, so a new LLC now owes the $800 starting in its first year. For the full list of startup costs, see The Complete Guide to LLC Costs in California.
Once your LLC elects S Corp status, the LLC annual tax no longer applies. Instead, the S Corp franchise tax takes its place, with the same $800 minimum. The two start to differ when your S Corp’s net income passes about $53,300, because that’s the point where the franchise tax calculation exceeds $800.
The LLC fee follows revenue, not profit
An SMLLC with $250,000 or more in total California income owes the LLC fee in addition to the LLC annual tax. California calculates this fee on gross receipts, and you make an estimated fee payment by June 15. As a result, a business with high revenue and thin margins can owe it in a year with little or no profit. As of 2026, the schedule looks like this:
| Total California income | LLC fee |
|---|---|
| Under $250,000 | $0 |
| $250,000 to $499,999 | $900 |
| $500,000 to $999,999 | $2,500 |
| $1,000,000 to $4,999,999 | $6,000 |
| $5,000,000 or more | $11,790 |
An LLC with an S Corp election doesn’t pay the LLC fee. For most solopreneurs, this fee won’t come into play. Still, if your revenue is near or above $250,000, it’s worth factoring into the comparison.
Timing matters: the 15-day rule
California also has a narrow exception for very short tax years. If an LLC’s taxable year lasts 15 days or fewer and it doesn’t do business in California during that time, it doesn’t need to file a California return or pay the LLC annual tax or LLC fee for that year. In practice, this matters most when you form an LLC or your election takes effect in the last two weeks of a calendar year. So if your formation or election date falls near year-end, plan the timing with a tax professional.
Payroll becomes part of the picture
Electing S Corp status means paying yourself a reasonable salary through payroll (see How Much Should You Pay Yourself? S Corp Salary Guide). In California, that starts with registering as an employer with the Employment Development Department (EDD), the state agency that manages payroll taxes. From there, your business generally pays state unemployment insurance and the employment training tax on your salary. Meanwhile, your payroll withholds California income tax from each paycheck, along with state disability insurance unless you opt out as a sole shareholder. Consistent, on-time payroll keeps your salary, withholding, and S Corp status in good standing, so set it up before the election takes effect.
How California taxes an S Corp
As it does federally, an S Corp in California works as a pass-through entity, meaning its income flows through to you as the owner. That said, California adds one business-level layer: the S Corp franchise tax on the business’s California net income, with the $800 minimum. Then you pay California personal income tax on your share of that same income on your state personal return. For a deeper look, see our California S Corp tax guide.
The business reports your share of its income on a California Schedule K-1, which your preparer completes alongside the federal and California business returns. Next, you use the K-1, along with the W-2 for your salary, to complete your California personal return. Keep in mind that the election doesn’t lower your California personal income tax.
One potential offset is California’s pass-through entity (PTE) elective tax. It lets an S Corp pay state income tax at the business level, which may help owners work around the federal cap on state and local tax (SALT) deductions. S Corps can use it, but SMLLCs can’t. Under current law, California extends the PTE tax through the 2030 tax year, as long as the federal SALT cap stays in place. Whether it helps depends on your income and how the federal SALT cap applies to you, so talk it through with a tax professional.
California Filings: SMLLC vs S Corp
Here’s what each structure files and pays for a calendar-year business, federal and state combined. For current deadlines, see the FTB’s due dates for businesses.
| Filing or charge | SMLLC | LLC with S Corp election |
|---|---|---|
| Federal business return | None separate; business income goes on your Individual Tax Return (Schedule C) | S Corp Tax Return (Form 1120-S), due March 15 |
| California business return | California LLC return (Form 568), due April 15 | California S Corp return (Form 100S), due March 15 |
| LLC annual tax | $800, due April 15 | N/A |
| LLC fee | Owed if total California income is $250,000 or more; estimated payment due June 15 | N/A |
| S Corp franchise tax | N/A | Greater of $800 or 1.5% of net income, paid through estimated payments (Form 100-ES), first due April 15 |
| Owner’s share of income | Goes directly on your personal returns | Federal Schedule K-1 and California Schedule K-1 (100S), prepared with the business returns |
| Personal returns | Federal and California returns with business income, plus quarterly estimated payments | Federal and California returns reporting your W-2 salary and K-1 income |
| Payroll | None, if no employees | Required to pay your owner salary |
| Secretary of State | Statement of Information every two years | Same; the business stays an LLC under state law |
A California Example: How the State Charges Apply
For example, take a business earning profit of $100,000 on less than $250,000 in revenue, with a $50,000 reasonable salary under the S Corp election. This example compares only California’s business-level charges. It doesn’t include federal taxes, California personal income tax, or payroll costs. For the federal payroll tax comparison, see our full LLC vs S Corp guide.
| SMLLC | S Corp election | |
|---|---|---|
| Business profit | $100,000 | $100,000 |
| Owner salary | N/A | $50,000 |
| California net income after payroll costs | $100,000 (no payroll) | About $46,000 (ER payroll tax ~$4K) |
| LLC annual tax (flat $800) | $800 | N/A |
| LLC fee (revenue under $250,000) | $0 | N/A |
| S Corp franchise tax (1.5% of net income, $800 minimum) | N/A | $800 |
| Total California business-level charges | $800 | $800 |
Since 1.5% of about $46,000 comes to about $690, the $800 minimum applies. We rounded net income, which reflects salary and employer payroll taxes. All figures use California rates as of 2026 and are for illustration only; results will vary.
At this profit level, California’s business-level charges come out the same under either structure. However, that changes in two situations. First, when the S Corp’s net income after payroll costs passes about $53,300, the S Corp franchise tax rises above $800. Second, when an SMLLC’s revenue reaches $250,000, the LLC fee applies on top of the LLC annual tax. In most cases, California’s charges aren’t the deciding factor on their own. Even so, they belong in the full comparison alongside federal payroll taxes and the added cost of running payroll.
Which Structure May Fit Your California Business
Staying an SMLLC may make sense if you:
- Are early in your business or still testing it, with profit generally under about $60,000
- Have a high-earning W-2 role alongside your business
- Prefer one California business return and no payroll to manage
- Have revenue under $250,000, so your California business-level charge stays at a flat $800
On the other hand, an S Corp election may be worth exploring if you:
- Have been self-employed for at least 1 to 2 years with consistent profit, generally over $80,000
- Are ready to run payroll and pay yourself a reasonable salary year-round
- Expect potential federal payroll tax savings to outweigh the S Corp franchise tax and the added cost of payroll and filings
- Have revenue near or above $250,000, where the LLC fee would otherwise apply
Keep in mind that these are guidelines, not rules. Any eligible business can stay an SMLLC or elect S Corp status. For that reason, running your own profit, salary, and revenue through the comparison with a tax professional is the most reliable way to decide. Still deciding whether you need an LLC at all?

FAQs About LLC vs S Corp in California
Is an S Corp worth it in California?
It can be, generally once your profit is consistent and high enough that potential federal payroll tax savings outweigh the S Corp franchise tax and the cost of running payroll. At many profit levels, California’s business-level charges come to $800 under either structure. As a result, the decision usually turns on the federal math. For a closer look, see our S Corp breakeven table.
Do I still pay the $800 California tax if my LLC elects S Corp status?
Generally, yes. The $800 LLC annual tax no longer applies, but the S Corp franchise tax takes its place. So you’ll owe the greater of the $800 minimum or 1.5% of the business’s California net income.
Does an LLC with an S Corp election still file Form 568 in California?
No. Instead, an LLC with an S Corp election files the California S Corp return (Form 100S) in place of the LLC return.
Does the California LLC fee depend on profit or revenue?
Revenue. California bases the LLC fee on total California income, which is closer to gross receipts than profit. The fee applies to SMLLCs with $250,000 or more in total California income, and it’s separate from the $800 LLC annual tax.
Do I need to file a separate S Corp election with California?
Generally, no. California piggybacks on the federal election. So when your business elects S Corp status with the IRS, California generally treats it as an S Corp too.
Does electing S Corp status lower my California income tax?
Generally, no. Your business profit faces California personal income tax under either structure. With an S Corp, the business also pays the S Corp franchise tax, and then you pay personal income tax on your share through your California K-1. In other words, the potential benefit of the election comes mainly from federal payroll taxes.
Support for Your California Business
