How to Start a Business in California: The Complete 2026 Guide

California has the largest state economy in the US — and the fifth largest economy in the world, ahead of India and the UK. If California were a country, it would be a G7 member. The market opportunity here is enormous, but so is the cost of doing business. Filing an LLC costs $70 and takes about 20 minutes online. Then the Franchise Tax Board sends you a bill for $800, every year, whether you made money or not.

This guide walks you through the full process of starting a business in California — from picking the right business structure to registering for state taxes. You’ll find a decision framework for choosing your entity type, a step-by-step breakdown of formation, a realistic cost table, and links to detailed guides for each stage.

You don’t need a lawyer to do this. You don’t need thousands of dollars (though California will certainly try). You need about an hour, an internet connection, and this page.

Choosing Your California Business Structure

This is the first decision you’ll make, and it shapes everything that follows — how you pay taxes, whether your personal assets are protected if something goes wrong, how much paperwork you deal with each year, and how easy it is to bring on investors down the road.

Here’s how the main entity types compare in California:

LLC — This is the most popular choice for California small businesses, and for good reason. You get liability protection without the rigid formality of a corporation. Profits pass through to your personal tax return, so you avoid double taxation. Filing costs $70 with the Secretary of State through BizFile Online. The catch is the $800/year franchise tax — due to the Franchise Tax Board regardless of how much (or little) you earn. If you’re reading this guide and aren’t sure what to pick, an LLC is almost certainly the right default.

Corporation — The better choice if you plan to raise venture capital or issue stock. Investors and VCs generally prefer the corporate structure — and in California’s startup ecosystem, that matters more than in most states. The filing fee is higher ($100), and the ongoing compliance requirements — board meetings, minutes, bylaws — are more demanding. You can make an S-Corp election with the IRS to get pass-through taxation while keeping the corporate structure. Corporations also owe the $800 franchise tax.

Sole proprietorship — The simplest option. No state filing, no fees, no franchise tax. You just… start doing business. The tradeoff is real, though: zero liability protection. If your business gets sued, your house, car, and savings are on the table. For anything beyond casual freelancing, this is a risk most people shouldn’t take. In California, where litigation is more common than in many states, the risk is amplified.

Partnership — Essentially a sole proprietorship with two or more people. Same lack of liability protection, same informality. If you’re going into business with a partner, form an LLC instead. Seriously. Partnerships without an operating agreement are lawsuits waiting to happen.

Each entity type has its own dedicated guide with full formation instructions — you’ll find links throughout this page.


8 Steps to Start Your California Business

Step 1: Choose Your Business Structure

Use the comparison above to decide. If you’re a solo founder or small team without plans to seek venture capital, an LLC gives you the best combination of protection and flexibility. If you’re still weighing the options, read the full entity comparison guide.

Step 2: Pick and Reserve Your Business Name

Search for available names using the Secretary of State’s BizFile Online business search. Your name must be distinguishable from any existing California business on file. If you’re forming an LLC, your name must include “LLC,” “L.L.C.,” or “Limited Liability Company.”

Found a name you like but aren’t ready to file? You can reserve it for 60 days for a $10 fee. This is optional — if you’re filing right away, skip it and save the $10.

Step 3: Appoint an Agent for Service of Process

Every California LLC and corporation needs an agent for service of process (also called a registered agent) — a person or service with a physical California address who receives legal documents and official state mail on your behalf. You can be your own agent if you have a California address, but that means your home address goes on the public record.

A registered agent service costs $100–$300/year and keeps your personal address private. Worth considering if you work from home.

Step 4: File Your Formation Documents

For an LLC, you’ll file Articles of Organization with the Secretary of State. For a corporation, it’s Articles of Incorporation. Both can be filed online through BizFile Online.

  • LLC filing fee: $70
  • Corporation filing fee: $100

Online filings typically process in 3–5 business days. Expedited processing is available: $350 for 24-hour service, $750 for same-day. Those fees sting, but if you need your entity formed quickly for a contract or bank account, the option exists.

Step 5: Get Your EIN from the IRS

An EIN (Employer Identification Number) is like a Social Security number for your business. You need it to open a bank account, hire employees, and file taxes. It’s free, and you can get one in about five minutes through the IRS website.

No cost. No waiting. Just do it right after you get your formation confirmation.

Step 6: File Your Statement of Information

This is a California-specific step that catches people off guard. Within 90 days of forming your LLC or corporation, you must file a Statement of Information with the Secretary of State.

  • LLC Statement of Information: $20 (then due every 2 years)
  • Corporation Statement of Information: $25 (then due annually)

The form lists your officers/managers, agent for service of process, and business address. File through BizFile Online. Miss the 90-day deadline and you’ll face penalties and potential suspension of your entity.

Step 7: Open a Business Bank Account

This is not optional if you want your liability protection to hold up. Mixing personal and business funds — called “commingling” — is one of the fastest ways to lose the legal shield your LLC provides.

Walk into a bank with your EIN confirmation, your filed Articles of Organization (or Incorporation), and a government-issued ID. Major California banks — Bank of America, Wells Fargo, Chase — as well as credit unions and online banks can open your account the same day or within a few days.

Step 8: Handle the Franchise Tax and State Tax Registration

This is the step that separates California from friendlier business states.

Franchise tax: Every LLC and corporation owes $800/year to the Franchise Tax Board (FTB). It’s due by the 15th day of the 4th month after formation. As of 2026, there is no first-year exemption — the AB 85 exemption expired at the end of 2023. You owe it from day one.

State income tax: California’s individual income tax rates range from 1% to 13.3% — the highest top rate in the country. If your business is a pass-through entity (LLC, S-Corp), your business income is taxed at your personal rate. C-Corps pay 8.84% at the entity level.

Sales tax: If you’re selling goods or certain services, register for a seller’s permit through the California Department of Tax and Fee Administration (CDTFA). California’s base sales tax rate is 7.25%, but local add-ons push it to 8.5%–10.75% depending on your location.

Employees: If you’re hiring, register with the Employment Development Department (EDD) for payroll taxes, unemployment insurance, and state disability insurance. California’s employer obligations are more extensive than most states.


How Much Does It Cost to Start a Business in California?

Here’s a realistic breakdown for forming an LLC — the most common choice:

ExpenseCost
LLC filing fee (Secretary of State)$70
Corporation filing fee (Secretary of State)$100
Name reservation (optional)$10
Statement of Information (LLC)$20
Agent for service of process$0 (yourself) to $300/yr (service)
EIN from the IRSFree
Franchise tax (FTB) — year one$800
Business license (local)$0–$300+ (varies by city)
Operating agreement$0 (DIY template) to $500+ (attorney-drafted)

Realistic total for a California LLC: $890 to $1,500, depending on your choices.

The $890 floor is if you file yourself, act as your own agent, use a free operating agreement template, and your city doesn’t charge for a business license. That’s the absolute minimum — and $800 of it is the franchise tax. The $1,500 end includes a registered agent service, a professionally drafted operating agreement, and a local business license.

That’s significantly more expensive than most states. The franchise tax is the main culprit. In Virginia, you can form and maintain an LLC for $150 in year one. In California, you can’t get below $890. It is what it is — plan for it.

Why Start a Business in California?

The costs are real. So are the advantages.

The largest consumer market in the US. Nearly 40 million people live in California. If you’re selling a product or service, you have access to a massive, diverse, and affluent customer base without crossing a state line. LA alone has more people than most US states.

The startup and tech ecosystem. Silicon Valley, San Francisco, and increasingly Los Angeles are global centers for technology, venture capital, and innovation. If your business needs access to investors, tech talent, or startup infrastructure, there’s no equivalent anywhere in the country. More venture capital flows through California than the next five states combined.

A diverse economy. Tech gets the headlines, but California’s economy is genuinely broad — agriculture (the state produces over a third of US vegetables and two-thirds of US fruits and nuts), entertainment (Hollywood is still Hollywood), international trade (the ports of Los Angeles and Long Beach handle more container traffic than any other US port complex), biotech, tourism, and professional services.

Talent pool. California is home to Stanford, UC Berkeley, UCLA, Caltech, USC, and dozens of other world-class universities. The talent pipeline is deep, especially in tech, engineering, healthcare, and creative fields. If you’re building a team, you’re fishing in one of the best-stocked ponds in the world.

Progressive business infrastructure. CalGold helps you identify every license and permit you need. BizFile Online handles formation and filings digitally. The state’s Small Business Development Centers (SBDCs) offer free one-on-one advising. California’s bureaucracy is real, but so are the tools they’ve built to help you deal with it.

International access. California’s ports, airports, and proximity to Asia and Latin America make it a natural base for businesses with international supply chains or customers. LAX and SFO are two of the busiest international airports in the country.

The California SBDC network deserves a special mention. They offer free advising from people who’ve actually started and run businesses. If you’re a first-time founder, book a session before you file anything. It costs nothing and can save you from expensive mistakes — especially in a state where the mistakes tend to be more expensive than average.

CalGold is the other underrated resource. It’s a state-run tool that identifies the specific licenses, permits, and registrations your business needs based on your industry and location. California’s licensing requirements are among the most complex in the country, and CalGold cuts through a lot of the confusion.


The $800 Franchise Tax — What You Need to Know

This deserves its own section because it’s the single biggest surprise for new California business owners.

Every LLC and corporation formed in California owes an $800 minimum franchise tax to the Franchise Tax Board, every year, regardless of revenue. You can make $0 and still owe $800. The tax is due by the 15th day of the 4th month after your entity is formed (so for a January formation, it’s due by April 15).

There is no first-year exemption as of 2026. California briefly offered one under AB 85 (2020–2023), but that program expired. New businesses formed in 2024 and beyond owe the full $800 from year one.

What happens if you don’t pay: The FTB will suspend your entity. A suspended entity can’t legally conduct business, file lawsuits, or defend itself in court. Getting reinstated requires paying all back taxes, penalties, and interest. Don’t let this happen.

How to plan for it: Budget the $800 from day one. Set it aside before you spend a dollar on anything else. It’s the cost of doing business in California, and it’s non-negotiable.

The silver lining: The franchise tax is the same whether you’re an LLC or a corporation, so it doesn’t factor into your entity-type decision. And for businesses earning good revenue, $800/year is ultimately a rounding error. The franchise tax hurts most when you’re pre-revenue or in the early stages — which is exactly when every dollar matters most.


Frequently Asked Questions

How long does it take to start an LLC in California?

Online filing through BizFile typically processes in 3–5 business days. Expedited 24-hour processing is available for $350, same-day for $750. From start to finish — name search, filing, getting your EIN, filing your Statement of Information — you could realistically have everything in place within one to two weeks.

Do I need a business license in California?

California doesn’t issue a single statewide business license. Licensing is handled at the city level, and requirements vary by location and industry. Most California cities require some form of business tax certificate or business license. Use CalGold to identify what your specific business needs, then contact your city’s finance department. Some professions also require state-level licensing through the Department of Consumer Affairs.

Can I form a California LLC if I live in another state?

Yes. You’ll need an agent for service of process with a physical California address, which is where a registered agent service comes in handy. You’ll be forming a domestic California LLC regardless of where you personally live. Be aware that if you live in another state, you may also need to register your California LLC as a foreign LLC in your home state — check your state’s requirements.

What’s the cheapest way to start a business in California?

A sole proprietorship costs $0 in state fees — there’s nothing to file, and there’s no franchise tax. But you get no liability protection. An LLC costs $70 with the Secretary of State, but you’ll also owe $800 in franchise tax and $20 for the Statement of Information — bringing your minimum to $890. That gets you liability protection, tax flexibility, and credibility with clients and banks.

Do I need an operating agreement for my California LLC?

California law (Corporations Code Section 17701.10) actually requires LLCs to have an operating agreement, though there’s no penalty for not having one and you don’t file it with the state. Without one, California’s LLC Act fills in the blanks for you — and its default rules on profit splits, voting rights, and what happens when a member leaves probably don’t match what you actually want. Even for a single-member LLC, put it in writing.

Can I avoid the $800 franchise tax?

Not if you want an LLC or corporation. The only entity types that don’t owe it are sole proprietorships and general partnerships — which offer no liability protection. Some people form their entity in another state (Nevada, Wyoming) to avoid the franchise tax, but if you’re actually doing business in California, you’ll need to register as a foreign entity and you’ll owe the $800 anyway. The FTB is aggressive about enforcement. Don’t try to get cute with this one.


What to Do Next

You know the process. Here’s your move:

  1. Decide on your entity type. If you’re not sure, go with an LLC — you can always change later, and it’s the right fit for the vast majority of California small businesses.
  2. Search for your business name on BizFile Online.
  3. File online. BizFile is straightforward. Have your agent for service of process information and a credit card ready.
  4. Budget for the franchise tax. Set aside $800 immediately. It’s due within a few months of formation, and the FTB doesn’t wait.
