California Business Formation
Last updated: August 2026
Choosing a business entity in California comes down to three questions: who is personally on the hook if something goes wrong, how the profits are taxed, and what it costs to keep the thing running each year. Most founders get pushed toward an LLC by default, and for many that is right — but not for a business taking outside investment, and not for a licensed professional, who cannot use one at all. Bay Legal, P.C. advises California founders on entity selection, formation, and the governing documents that decide how owners deal with each other.
Definition: Business formation is the legal process of selecting an entity type, filing it with the Secretary of State, and putting in place the documents that govern ownership and management.
Jayson helped us through the process and worked with us to find a way for the new company to be able to accept outside investors. He also helped all three partners to structure our ownership of the new company in ways that were advantageous, from a tax and retirement standpoint, to us as individual investors/owners.

Which entity should you choose?
Five structures cover almost every California business. The table compares them on what actually differs.
| Entity | Personal liability | Taxation | Annual state minimum | Best fit |
|---|---|---|---|---|
| Sole proprietorship | Unlimited — your house and savings are exposed | Pass-through | None | Single owner, low risk, testing an idea |
| General partnership | Unlimited, and joint for your partner’s acts | Pass-through | None | Rarely the right answer; usually a default nobody chose |
| Limited partnership | General partners unlimited; limited partners capped at their contribution | Pass-through | $800 | Investment vehicles with passive investors |
| LLC | Limited to the entity | Pass-through by default | $800, plus a fee on gross receipts | Most small and mid-sized California businesses |
| Corporation | Limited to the entity | C corp taxed twice; S corp pass-through | $800 | Businesses raising venture capital or issuing stock |
The row that decides most cases is the last one. An LLC is simpler and cheaper to run, but institutional investors will generally not buy into one — they want preferred stock in a Delaware or California corporation. A founder who intends to raise a priced round is usually better off incorporating from the start than converting later, and conversion is more expensive than most people expect.
Licensed professionals are a separate case entirely. See the section below.
What does it actually cost to form and keep a California entity?
More in ongoing tax than in filing fees, and the ongoing figure is the one founders miss. Every LLC, limited partnership, and corporation doing business in California owes an annual minimum franchise tax of $800 — imposed on LLCs by Revenue and Taxation Code section 17941 and on corporations by section 23153. It is owed whether the business made money or not.
LLCs owe a second charge on top. Under Revenue and Taxation Code section 17942, an LLC with California total income above $250,000 pays a graduated fee in addition to the $800, rising in bands as revenue increases. A profitable LLC can therefore pay materially more in state-level charges than an S corporation with the same revenue, which is one of the few genuine tax arguments for incorporating.
Filing itself is comparatively cheap. Articles are filed with the California Secretary of State, and an initial Statement of Information follows within 90 days — biennially thereafter for LLCs under Corporations Code section 17702.09, annually for corporations under section 1502. Missing a Statement of Information leads to penalties and eventually suspension, and a suspended entity cannot sue, defend a lawsuit, or enforce a contract.
It looks great to us… thank you Jayson!

Why do the governing documents matter more than the filing?
Because the filing creates the entity and the documents decide what happens between the people who own it. Articles of Organization are a form. An operating agreement is the contract that determines who can sell, who can be bought out, what happens when someone dies or wants to leave, how deadlock is broken, and who has authority to sign.
California LLCs are governed by the Revised Uniform Limited Liability Company Act at Corporations Code section 17701.01 and following, corporations by the General Corporation Law at section 200 and following, and partnerships by the Uniform Partnership Act at section 16100 and following. Each supplies default rules where the documents are silent — and the defaults rarely match what the owners would have agreed if anyone had asked them.
The recurring failure is a two-owner business with no operating agreement, a fifty-fifty split, and no deadlock provision. When those two owners stop agreeing, there is no mechanism to resolve it and no way for either to exit. That dispute is the most common business matter this firm sees, and it is entirely preventable at formation for a fraction of what litigating it costs.
Do you have to file a beneficial ownership report?
If your company was formed in the United States, no. This changed, and a great deal of published guidance has not caught up. The Corporate Transparency Act originally required most U.S. companies to report beneficial ownership information to FinCEN. An interim final rule in March 2025 exempted domestic reporting companies, and a final rule from FinCEN effective 14 August 2026 made that permanent. U.S. companies and U.S. persons are exempt, and FinCEN is deleting previously reported information about U.S. persons from its database.
Who still has to file: entities formed under the law of a foreign country that have registered to do business in a U.S. state. Those must file within 30 calendar days of receiving notice that their registration is effective, and they do not report U.S.-person beneficial owners.
A separate point worth knowing, because it catches people who read only the federal headline: some states now operate their own beneficial ownership regimes, filed with the state rather than with FinCEN. The federal exemption does not touch those. A California business registered to do business elsewhere should check the position in that state.
What if you are a licensed professional?
Then an LLC is not available to you. California does not permit licensed professionals to render professional services through an LLC. The vehicle is a professional corporation under the Moscone-Knox Professional Corporation Act, Corporations Code section 13400 and following, which restricts share ownership to licensees of the same profession and imposes naming and governance requirements that vary by licensing board.
This affects doctors, dentists, lawyers, accountants, architects, engineers, veterinarians, therapists, and others. It is the single most common formation error the firm sees among professionals, usually because an online formation service filed an LLC without asking what the client did for a living. Unwinding it after the fact is expensive and can raise licensing questions.
What comes after formation?
- Obtain an EIN from the IRS, and open a business bank account in the entity’s name. Commingling personal and business funds is the fastest way to lose the liability protection the entity was formed to provide.
- File the initial Statement of Information within 90 days, then on the recurring schedule.
- Sign the governing documents. An operating agreement or bylaws, adopted rather than merely drafted, plus a buy-sell agreement where there is more than one owner.
- Issue the ownership interests properly — membership certificates or stock, with a written record. Founders frequently cannot prove who owns what three years later.
- Register for state and local requirements — city business licence, seller’s permit, employment development registration if hiring, and any industry-specific licence.
- Get worker classification right from the first hire. Under Labor Code section 2775, a worker is presumed an employee unless the hiring entity satisfies all three parts of the ABC test. Misclassification is among the most expensive early mistakes a California business can make.

Frequently Asked Questions
Should I form an LLC or a corporation in California?
An LLC for most small and mid-sized businesses: simpler governance, pass-through taxation, and fewer formalities. A corporation if you intend to raise venture capital, since institutional investors buy preferred stock and generally will not invest in an LLC. Licensed professionals cannot use an LLC at all and must form a professional corporation instead.
What does it cost to keep a California entity each year?
Every LLC, limited partnership, and corporation doing business in California owes an $800 annual minimum franchise tax under Revenue and Taxation Code sections 17941 and 23153, payable whether or not the business is profitable. LLCs with California total income above $250,000 owe a graduated fee on top under section 17942.
Do I have to file a beneficial ownership report with FinCEN?
Not if your company was formed in the United States. FinCEN exempted domestic reporting companies by interim rule in March 2025, and a final rule effective 14 August 2026 made that permanent. Only entities formed under foreign law and registered to do business in a U.S. state must still file, within 30 days of effective registration.
Do I really need an operating agreement?
Yes, and it matters more than the filing. Without one, California’s default statutory rules govern what happens when owners disagree, when someone wants out, and when someone dies — and those defaults rarely match what the owners would have chosen. A two-owner business with a fifty-fifty split and no deadlock provision has no way to resolve a stalemate.
Can I form an LLC if I am a licensed professional?
No. California does not permit professional services to be rendered through an LLC. Doctors, dentists, lawyers, accountants, architects, engineers, and others must use a professional corporation under the Moscone-Knox Act, Corporations Code section 13400 and following, which restricts ownership to licensees of the same profession.
What happens if I miss a Statement of Information filing?
Penalties first, then suspension by the Secretary of State. A suspended entity cannot sue, defend a lawsuit, or enforce its contracts, and revival takes time and money. LLCs file biennially and corporations annually, with the first one due within 90 days of formation.
Can I convert my LLC to a corporation later?
Yes, through a statutory conversion, but it costs more than incorporating at the outset and can raise tax consequences depending on the assets and timing. A founder who expects to raise a priced round within a year or two is usually better off starting as a corporation.
What is the ABC test, and why does it matter at formation?
Labor Code section 2775 presumes a worker is an employee unless the hiring entity proves all three parts of the ABC test — freedom from control, work outside the usual course of business, and an independently established trade. Misclassifying early contractors is among the most expensive mistakes a new California business makes.
Related Questions
Should I form in Delaware instead of California?
If you do business in California you will register here and pay the $800 minimum regardless, so Delaware adds a second set of fees. It is usually worth it only for companies raising institutional capital, where investors expect Delaware corporate law.
Do I need a registered agent?
Yes. Every California entity must maintain an agent for service of process with a physical California street address. You can serve as your own, though many owners prefer a commercial agent to keep their home address off the public record.
What is a DBA, and do I need one?
A fictitious business name statement, filed with the county, letting you trade under a name other than your legal entity name. It creates no entity and no liability protection — it is a name registration, nothing more.
When should I get a buy-sell agreement?
At formation, while everyone still agrees. It fixes what happens when an owner dies, becomes disabled, divorces, or wants out, and it is far cheaper to negotiate before anyone knows which side of it they will be on.
Does forming an entity protect me from my own negligence?
No. An entity separates business liabilities from your personal assets, but you remain personally liable for your own wrongful acts. Professionals in particular are personally liable for their own malpractice regardless of the entity.
