How to Start a Business in California (2026 Guide)
Starting a business in California comes down to five decisions: the legal structure you register, the name you can actually claim, who accepts legal mail on your behalf, how you register for tax, and which local licences apply where you trade. Get those right in the first fortnight and everything afterwards — banking, payroll, marketplace approvals, investor paperwork — falls into place. Get them wrong and you spend months correcting filings with the California Secretary of State.
California charges $70 to register a new LLC and takes 5-8 business days to approve a standard filing. Ongoing state maintenance runs $800 per year. The largest consumer market in the US, deep venture capital and unmatched access to technical talent. This guide walks through the whole sequence in the order the state actually expects it, with the California-specific costs, deadlines and traps that generic startup advice leaves out.

Step-by-step: starting a business in California
- 1
Choose the right structure for California
Most owners register an LLC: liability protection, pass-through taxation and light formalities. Register a C corporation instead if you plan to raise venture funding or issue stock options — investors in Los Angeles and elsewhere expect it. An S corporation is a tax election you can layer on later, once profit is high enough to justify running payroll. Sole proprietorships need no filing at all in California, but they leave your personal assets exposed.
- 2
Clear your name with the California Secretary of State
Search the California Secretary of State business database for exact and confusingly similar names before you commit. California requires an LLC designator such as "LLC" or "Limited Liability Company" in the legal name, and blocks names implying a bank, insurer or government body without approval. Check the matching domain and a federal trademark search at the same time — state approval does not give you national trademark rights.
- 3
Appoint a California registered agent
Every California entity must continuously maintain a registered agent with a physical street address in the state, available during business hours. You can act as your own agent if you live in California, but your home address becomes public record and a missed lawsuit notice can turn into a default judgment. Commercial agents scan and forward everything the same day.
- 4
File your formation documents and pay the $70 fee
Submit Articles of Organization (LLC) or Articles of Incorporation (corporation) to the California Secretary of State with your name, agent, address and organiser details. Standard approval takes 5-8 business days; expedited handling shortens that in most cases. Keep the stamped certificate — banks, payment processors and San Francisco landlords all ask for it.
- 5
Get your EIN and open a US business bank account
The EIN is your federal tax ID and is needed for banking, payroll and marketplace seller accounts. Founders with an SSN or ITIN receive one online in minutes; non-residents apply by fax or mail and typically wait one to two weeks. Open a dedicated business account immediately — mixing personal and business money is the fastest way to undermine the liability protection you just paid for.
- 6
Register for California tax and local licences
California charges every LLC a minimum $800 annual franchise tax plus a gross-receipts fee once revenue passes $250,000. Cities run their own licence regimes — Los Angeles, San Francisco and San Diego each require registration within weeks of your first sale. Handle these before your first invoice: back-registration penalties are far more expensive than registering early, and payment processors increasingly verify licence status.
- 7
Put your compliance calendar in place
Diary your California ongoing filing ($800 per year), your federal return date and any local licence renewals the day your entity is approved. Store the formation certificate, operating agreement, ownership ledger and every filed report in one place — this is exactly the pack a bank, lender or acquirer will request.
California taxes and ongoing costs you should budget for
California charges every LLC a minimum $800 annual franchise tax plus a gross-receipts fee once revenue passes $250,000. On top of that, an LLC's profits pass through to the owners' federal returns by default, so your first year's cash planning should assume quarterly estimated federal payments once you are profitable.
Ongoing state maintenance in California costs $800 per year, which is the single figure most founders forget when comparing states. Add a registered agent, a bookkeeping subscription and any city licence renewals, and a realistic first-year running cost sits well above the headline $70 filing fee. Budgeting for it up front avoids the administrative dissolution that follows a missed report.
Licences, permits and local rules in Los Angeles, San Francisco and San Diego
Cities run their own licence regimes — Los Angeles, San Francisco and San Diego each require registration within weeks of your first sale. Requirements differ by municipality, so a business operating in Los Angeles may need a permit that an identical business in San Diego does not. Check the city clerk's site for your trading address, not just the state portal.
Regulated trades — food service, construction, childcare, health, transport and anything involving alcohol — need a professional or occupational licence before their first sale anywhere in California. If you sell physical goods, register for sales tax in every jurisdiction where you have nexus, including inventory held in a third-party warehouse.
Should you form in California or somewhere else?
If you live, hire or hold property in California, form here. Registering in Delaware or Wyoming while operating from Los Angeles means registering again as a foreign entity in California, paying two sets of fees and maintaining two registered agents — the classic false economy in online formation advice.
Forming elsewhere genuinely makes sense in two cases: you are raising venture capital and investors expect a Delaware C corporation, or you are a non-resident with no US physical presence choosing a low-maintenance state. The largest consumer market in the US, deep venture capital and unmatched access to technical talent.
The California economy: where the demand is
California's strongest sectors are technology and software, entertainment and agriculture and food, concentrated around Los Angeles, San Francisco and San Diego. New entrants usually win faster by serving an existing supply chain in those sectors than by building demand from scratch — suppliers, contractors and service providers to established industries have shorter sales cycles and clearer buyers.
Before you file, talk to ten potential customers in that market and get one to commit money or time. Formation is inexpensive; the annual reports, tax filings and bookkeeping that follow are not worth carrying for an idea you have not tested.

Starting a business in California: frequently asked questions
- How much does it cost to start a business in California?
- Registering an LLC with the California Secretary of State costs $70, with ongoing state maintenance of $800 per year. Add a registered agent, any Los Angeles or county licence, and your EIN — which is free from the IRS — and most California founders spend a few hundred dollars in year one.
- How long does it take to register a business in California?
- Standard California Secretary of State processing takes 5-8 business days from submission. Expedited handling is available in most cases, and the EIN follows the same day for owners with an SSN or ITIN, or one to two weeks for non-residents.
- Do I need to live in California to start a business there?
- No. California places no residency or citizenship requirement on LLC members, managers or corporate shareholders. You must, however, maintain a registered agent with a physical street address inside California for as long as the company exists.
- What licences does a new California business need?
- Cities run their own licence regimes — Los Angeles, San Francisco and San Diego each require registration within weeks of your first sale. Regulated trades need their professional licence before the first sale, and sellers of taxable goods need to register for tax in every jurisdiction where they have nexus.
- What taxes will my California business pay?
- California charges every LLC a minimum $800 annual franchise tax plus a gross-receipts fee once revenue passes $250,000. Federal tax applies on top: pass-through on your personal return for an LLC, or corporate tax for a C corporation, with quarterly estimated payments once you are profitable.
- Is an LLC or a corporation better in California?
- An LLC suits most California operators — simpler paperwork, pass-through tax and flexible ownership. Choose a C corporation if you intend to raise institutional funding or grant equity to employees. You can also elect S corporation tax treatment on an LLC later, once profits justify payroll.
- What happens if I miss a California filing deadline?
- The state charges late penalties and eventually administratively dissolves the entity, which removes your liability shield and can freeze your bank account. Reinstatement is possible but costs more than the original filing, so we track the deadlines for every client we file for.
