Choosing a Business Entity in California

Entity selection is usually presented as a liability question. In California it is mostly a tax and cost question, because the state imposes entity-level charges that have nothing to do with profit and that differ sharply depending on which box you check.

A California LLC pays $800 a year whether it earns anything or not, plus a gross receipts fee that ignores whether the business was profitable. A California corporation pays the greater of $800 or 1.5% of net income — but is exempt from the minimum in its first year. That exemption used to exist for LLCs too. It does not anymore, and a great deal of outdated advice still says otherwise.

We advise founders and existing businesses on formation and restructuring throughout Temecula, Murrieta, San Diego, Riverside, and San Bernardino.

What Each Entity Costs in California

Entity	California entity-level tax	First year
Sole proprietorship	None	None
LLC	$800 minimum + gross receipts fee	$800 due
S corporation	Greater of $800 or 1.5% of net income	Minimum waived
C corporation	Greater of $800 or 8.84% of net income	Minimum waived

The LLC gross receipts fee under R&TC 17942 is charged on revenue, not profit:

• Under $250,000 — no fee
• $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 and above — $11,790

A distribution business with $3 million in revenue and thin margins pays $6,800 to the FTB before any income tax is calculated. For high-revenue, low-margin operations, this alone can decide the entity question.

Liability Protection Is Not the Differentiator

LLCs and corporations both provide limited liability. Neither protects against your own negligence or personal guarantees, and both can be pierced where formalities are ignored, funds are commingled, or the entity is undercapitalized.

What actually varies is tax treatment, administrative burden, and how well the structure accommodates outside investment. Choose on those.

The Self-Employment Tax Question

This drives most entity conversations, and the arithmetic is straightforward.

A sole proprietor or standard LLC member pays self-employment tax — 15.3% up to the Social Security wage base, 2.9% Medicare above it, plus 0.9% additional Medicare over $200,000 single or $250,000 joint — on all net earnings.

An S corporation owner-employee pays payroll tax only on reasonable W-2 wages. Distributions above that are not subject to employment tax. On $150,000 of profit with a defensible $90,000 salary, the $60,000 in distributions escapes roughly 15.3% — real money, repeating annually.

Three constraints keep this from being free:

Reasonable compensation is enforced. Both the IRS and the FTB examine S corporations paying token salaries against large distributions. The standard is what you would pay someone else to do the same work. Understate it and the IRS reclassifies distributions as wages with payroll tax, penalties, and interest.

California takes 1.5% of the same dollars. Salary is deductible to the corporation, so the 1.5% franchise tax falls largely on the distribution slice — precisely the slice generating the federal savings. California taxes what you are optimizing, which moves the break-even point meaningfully compared to a no-tax state.

Payroll is a real obligation. Quarterly filings, EDD registration once wages reach $100 in a quarter, and California SDI at 1.3% for 2026 with no wage cap — unlike Social Security, it applies to every dollar of salary.

As a rough guide, S corporation treatment starts to pay for itself somewhere around $60,000 to $80,000 of profit above a reasonable salary. Below that, added compliance cost often exceeds the savings.

Where OBBBA and California Diverge

Federal law changed substantially in 2025. California’s conformity date is January 1, 2025 under Senate Bill 711 — before OBBBA — so the state does not follow it. For entity planning, the gaps that matter:

• Section 199A QBI deduction — up to 20% of qualified business income federally for pass-throughs; no California equivalent
• Bonus depreciation — 100% permanent federally; never adopted by California
• Section 179 — $2.5 million federally against California’s $25,000 with a $200,000 phaseout
• QSBS — Section 1202 exclusion expanded federally; no California exclusion at all

QSBS is the one that changes structural decisions. Only C corporation stock can qualify, and OBBBA raised the exclusion cap to $15 million with tiered holding periods for stock issued after July 4, 2025. For a founder building toward an exit, that can outweigh years of pass-through efficiency — but a California resident still pays California tax on the entire gain, so the analysis has to be run on both returns.

The Pass-Through Entity Elective Tax

California’s PTE elective tax, extended through 2030 by Senate Bill 132, lets a qualifying pass-through pay 9.3% at the entity level. That payment is deductible federally without regard to the SALT cap, and the owner takes a credit against California tax.

For 2026 and later, missing the June 15 prepayment no longer voids the election, but it cuts the owner’s credit by 12.5% of the shortfall. For profitable S corporations and multi-member LLCs, this is frequently the largest single planning item on the return — and it only exists for pass-throughs, which is a point in their favor against C corporation treatment.

Formation Mechanics and the Ongoing Obligations

Filing with the Secretary of State is the easy part. What follows is where businesses fall out of compliance:

• Statement of Information — due within 90 days of formation, then annually for corporations or biennially for LLCs
• EDD registration — required within 15 days once you pay $100 in wages in a quarter; see EDD
• Seller’s permit from CDTFA if you sell tangible goods
• S election — Form 2553 within 2 months and 15 days of formation for the current year
• Beneficial ownership reporting — under FinCEN’s March 2025 rule, domestic entities are exempt; only foreign reporting companies file. See Corporate Transparency Act.

An entity that stops filing gets suspended or forfeited by the FTB, losing the right to conduct business, defend a lawsuit, or enforce its contracts — and contracts entered while suspended may be voidable. Owners usually discover this mid-transaction. See unfiled returns.

Converting Later Is Not Free

Owners often plan to “start simple and change it later.” Sometimes that works. Often it carries costs nobody priced in at formation.

Converting a partnership or LLC into a corporation is generally tax-deferred under Section 351 if the requirements are met, but it resets holding periods and — critically — does not create QSBS retroactively. Section 1202 qualification generally runs from the issuance of qualifying stock, so appreciation accrued before the conversion does not become eligible.

Converting a C corporation to an S corporation triggers built-in gains tax on appreciation existing at conversion if assets are sold within the recognition period, and accumulated earnings and profits carry over with passive income restrictions attached. Revoking an S election imposes a five-year wait before re-electing without IRS consent.

None of this makes conversion wrong. It makes the initial choice worth more thought than a filing service’s default recommendation, particularly for a business that might be sold.

Frequently Asked Questions

Does my California LLC really owe $800 in its first year?

Yes. The AB 85 first-year waiver applied only to tax years 2021 through 2023 and expired. Every LLC formed from 2024 onward owes the $800, due the 15th day of the fourth month after formation. Corporations, by contrast, remain exempt from the minimum in their first year.

Should I form in Nevada or Wyoming to avoid California tax?

No. If you are doing business in California, the entity must register here and owes the $800 plus applicable fees regardless of where it was organized — and you add a second state’s filing costs. This is among the most expensive pieces of bad advice in circulation.

When does an S election make sense?

Generally once profit exceeds a reasonable salary by roughly $60,000 to $80,000. Below that, payroll and compliance costs often exceed the self-employment tax savings, especially with California’s 1.5% franchise tax on the same income.

Can an LLC be taxed as an S corporation?

Yes, by election — a common structure that keeps LLC formalities while obtaining S corporation payroll treatment. Note the LLC gross receipts fee still applies.

Does California recognize my federal S election?

California honors the federal election, but that does not waive the 1.5% franchise tax, the $800 minimum, or the Form 100S filing requirement.

Which entity is best for raising outside investment?

A C corporation, generally a Delaware C corporation, because institutional investors expect that structure and only C corporation stock can qualify for QSBS treatment.

Model the Costs Before You File

Entity choice is cheap to get right at formation and expensive to change afterward — conversions can trigger gain, reset holding periods, and forfeit QSBS eligibility. The variables worth modeling are revenue against the LLC fee tiers, profit against the S corporation break-even, and whether an eventual sale makes C corporation treatment worth the double tax.
