Starting a business in California in 2026 can be an exciting prospect. The state boasts a huge consumer market, strong technology and innovation sectors, major cities, investor access, and prospects in a variety of industries, including professional services and e-commerce, as well as food, construction, healthcare, entertainment and technology.

But starting a business in California involves more than coming up with a good idea. You need to choose the right business structure, register your business, understand federal and California taxes, check local licenses and permits, set up accounting, and follow employment rules if you hire workers.

The California Secretary of State recommends starting with a business plan, choosing a business structure, handling tax and employer identification requirements, and checking the licenses and permits that apply to your business. Requirements can vary depending on your business activity, city, county, and location.

Here is a practical guide to how to start a business in California in 2026, from choosing your business idea to getting ready to operate.

Why Start a Business in California in 2026?

California is one of the largest business markets in the United States. Entrepreneurs can serve a huge customer base while benefiting from established infrastructure, major business centers, technology ecosystems, and access to domestic and international markets.

Cities such as Los Angeles, San Diego, San Francisco, San Jose, Sacramento, Irvine, and Oakland have different business environments and operating costs.

California also has opportunities in industries such as:

Technology and artificial intelligence
E-commerce
Professional services
Healthcare
Construction
Real estate
Food and restaurants
Entertainment and media
Tourism and hospitality
Renewable energy
Logistics
Manufacturing
Digital marketing

However, a large market does not automatically mean that a business will succeed.

Before registering your company, research your customers, competitors, startup expenses, pricing, taxes, and expected revenue.

1. Choose a Business Idea That Fits the California Market

The first step is deciding exactly what your business will sell.

Think about:

Who your target customers are
What problem your business solves
How much customers are willing to pay
Who your competitors are
Whether you will operate online, offline, or both
Where your customers are located
How much money you need to launch
Whether you will need employees
Whether your business requires special licences or permits
How you will generate your first customers

California is a large and diverse state, so a business model that works in San Francisco may not work in a smaller California city.

Your business idea should therefore be connected to a specific customer and location rather than simply being based on a general trend.

2. Research Your Market and Competition

Once you have a business idea, research whether there is genuine demand for your product or service.

Study businesses operating in your target area and compare their:

Prices
Products and services
Customer reviews
Locations
Websites
Social media
Advertising
Customer experience
Strengths and weaknesses

Ask yourself:

Who will buy from me?

Why would they choose my business instead of an existing competitor?

How much will it cost to acquire a customer?

Can I make a profit after rent, salaries, insurance, taxes, marketing, and other expenses?

California has substantial differences in operating costs between locations. Your market research should therefore include the specific city or county where you plan to operate.

3. Create a Business Plan

A business plan gives you a roadmap for launching and growing your company.

The California Secretary of State recommends beginning the process with a business plan covering areas such as sales, marketing, advertising, promotion, and location.

Your plan can include:

Business description
Target market
Competitor analysis
Products or services
Pricing strategy
Marketing strategy
Sales strategy
Startup costs
Monthly operating expenses
Revenue projections
Staffing requirements
Funding requirements
Growth plans

You do not necessarily need a 50-page document. A clear financial and operating plan can be more useful than a long document that you never use.

4. Choose Your California Business Structure

One of the most important decisions is choosing your legal structure.

California recognizes several business structures, including:

Sole proprietorship
Partnership
Limited Liability Company (LLC)
Corporation
Limited Partnership
Limited Liability Partnership

The California Secretary of State points out that your decision can have an impact on liability, taxes, ownership, management, and state and federal requirements.

Sole Proprietorship vs LLC vs Corporation

Feature Sole Proprietorship LLC Corporation

Best suited to Individual owners Small and growing businesses Businesses seeking a corporate structure

Separate legal entity No Yes Yes

Liability protection Limited Generally available Generally available

Setup Simpler More formal More formal

Multiple owners No separate entity structure Yes Yes

Investment potential Limited Good Often better suited to outside investment

Administration Generally lighter Moderate More formal

There is no universally best structure.

A freelancer may choose a sole proprietorship, while a growing company may prefer an LLC. A startup planning to raise substantial outside investment may consider a corporation.

Because tax and liability consequences can be significant, consider speaking with a qualified attorney or tax professional before choosing your structure.

5. Choose and Check Your Business Name

If you are forming an LLC or corporation, check whether your proposed name is available.

California allows business entity name reservations through the Secretary of State. A name can generally be reserved for 60 days.

The Secretary of State’s business search can help you perform a preliminary check, but the state warns that the search is not a formal determination of name availability.

You should also check:

Domain name availability
Social media usernames
Federal trademarks
Local business names
Similar brands in your industry

If you operate under a name different from your legal business name, you may need to register a fictitious business name (DBA) with the appropriate California county.

6. Register Your Business With the California Secretary of State

If you choose an LLC or corporation, you will generally need to file formation documents with the California Secretary of State.

For an LLC, you file Articles of Organization.

For a corporation, you file Articles of Incorporation.

California’s online bizfile system allows businesses to complete many entity filings electronically.

For a California LLC, the current Secretary of State fee schedule lists:

Articles of Organization: $70
Initial Statement of Information: $20
Statement of Information: due within 90 days of initial registration and every two years thereafter.

Fees and filing requirements can change, so check the current Secretary of State fee schedule before submitting your documents.

7. Prepare an Operating Agreement or Corporate Documents

If you establish an LLC, create an operating agreement explaining how the company will be managed.

An operating agreement can cover:

Ownership percentages
Member responsibilities
Profit distributions
Voting rights
Management
Adding new members
Selling ownership
Resolving disputes
What happens if a member leaves

California requires an LLC to have an operating agreement, but the agreement is maintained by the business rather than filed with the Secretary of State.

Corporations should also establish appropriate bylaws, records, and governance procedures.

8. File Your Statement of Information

After creating an LLC or corporation, you need to keep your business information updated with the California Secretary of State.

California requires corporations and LLCs to file Statements of Information according to the applicable filing schedule.

For LLCs, the initial Statement of Information is due within 90 days and subsequent statements are generally required every two years.

Since August 1, 2026, California also requires user access to be established for online Statement of Information filings through bizfile Online.

Do not ignore these filings. Failure to file required statements can lead to penalties and potentially suspension or forfeiture of the business entity.

9. Get an Employer Identification Number

An Employer Identification Number (EIN) is a federal tax identification number issued by the IRS.

You may need an EIN if you:

Hire employees
Operate as a corporation or partnership
File certain federal tax returns
Open a business bank account
Apply for certain licenses or business credit

The IRS allows eligible businesses to apply for an EIN online for free.

If you are forming an LLC, partnership, or corporation, the IRS says to form the entity with the state before applying for the EIN.

Be careful with websites that charge a fee for an EIN. The IRS provides the application directly at no charge.

10. Register for California Taxes

Your tax obligations depend on your business structure, activities, employees, sales, and other factors.

California businesses may have obligations involving:

Franchise or income tax
Sales and use tax
Payroll taxes
Withholding
Estimated tax payments
Industry-specific taxes and fees

An LLC, corporation, sole proprietorship, and partnership can have very different tax requirements.

For example, California’s current corporate tax rate for corporations other than banks and financial corporations is 8.84%, while the S corporation rate is 1.5%, subject to the applicable rules.

Do not assume that your federal tax treatment automatically tells you everything about your California tax obligations.

11. Understand California’s $800 LLC Annual Tax

One important cost for many California LLC owners is the state’s annual LLC tax.

For 2026, California’s Franchise Tax Board states that an LLC doing business in California, or one with Articles of Organization accepted or a certificate of registration issued by the Secretary of State, is generally subject to an $800 annual tax.

LLCs with California income above $250,000 can also face an additional annual fee based on income. Current FTB thresholds include:

California income LLC fee

250,000–499,999 $900

500,000–999,999 $2,500

1million–4,999,999 $6,000

$5 million or more $11,790

This is an important cost to include in your financial plan.

12. Apply for a California Seller’s Permit if Required

If your business sells or leases taxable tangible personal property in California, you may generally need a seller’s permit from the California Department of Tax and Fee Administration (CDTFA).

The CDTFA says businesses selling or leasing merchandise, vehicles, or other tangible personal property in California are generally required to register and pay sales tax on taxable sales.

A seller’s permit itself has no charge, although CDTFA may require a security deposit in certain circumstances.

You can register online through the CDTFA.

Not every service business needs a seller’s permit, so determine whether your particular products and activities fall within California’s sales-tax requirements.

13. Check Business Licences and Permits

Registering your LLC or corporation does not automatically give you permission to operate every type of business.

Depending on what you do and where you operate, you may need:

City business licence
County registration
Professional licence
Health permit
Building permit
Zoning approval
Fire permit
Food permit
Contractor licence
Environmental permit
Industry-specific licence

California’s CalGOLD system provides information about business permits and licensing requirements at state, county, and local levels.

For example, a restaurant may have very different requirements from an online marketing agency.

Always check the requirements for the specific city and county where you operate.

14. Choose Your Business Location Carefully

Location can have a major effect on your startup costs and customer acquisition.

Before signing a commercial lease, consider:

Rent
Security deposit
Utilities
Parking
Foot traffic
Competition
Zoning
Local taxes
Local minimum wage
Building requirements
Customer demographics
Accessibility

A business that depends on local customers may benefit from a high-traffic location, while an online company may be able to operate with significantly lower physical overhead.

Do not sign a long-term lease before confirming that the location is legally suitable for your business activity.

15. Open a Business Bank Account

Once your business is established, separate business and personal finances.

You may need:

EIN
Formation documents
Business address
Identification
Operating agreement or corporate documents
Business licence, depending on the bank

A separate business bank account makes it easier to track:

Revenue
Expenses
Taxes
Payroll
Supplier payments
Profit
Cash flow

Avoid using your personal account for routine business transactions.

Keeping finances separate can also make accounting and tax reporting much easier.

16. Get the Right Business Insurance

Insurance is another important part of starting a California business.

Depending on your industry, you may consider:

General liability insurance
Professional liability insurance
Commercial property insurance
Workers’ compensation insurance
Commercial auto insurance
Product liability insurance
Cyber insurance
Business interruption insurance

The right coverage depends on the risks associated with your business.

For example, a construction company has different risks from an online consulting business.

If you hire employees, make sure you understand California’s workers’ compensation requirements and other employment obligations.

17. Register as an Employer if You Hire Workers

Hiring employees creates additional responsibilities.

California employers may need to register with the Employment Development Department (EDD) and handle payroll tax reporting and payments.

The EDD states that a business must register as an employer within 15 days when it becomes a subject employer.

Employers also have requirements for reporting new employees.

The EDD provides an online e-Services for Business system that can be used to register, file reports, make payments, and manage an employer payroll tax account.

18. Understand California Minimum Wage

California’s employment rules can significantly affect your operating costs.

As of January 1, 2026, California’s statewide minimum wage is $16.90 per hour for covered employees, although some industries and local governments have higher minimum wages.

For example, certain fast-food workers are covered by a separate minimum wage of $20 per hour under California law. Some healthcare workers also have different minimum wage rules.

Some cities and counties also impose higher local minimum wages.

Therefore, before hiring employees, check the state, industry, and local wage rules that apply to your business.

19. Set Up Proper Accounting From Day One

Do not wait until tax season to organize your finances.

Create a system for tracking:

Sales
Expenses
Invoices
Sales tax
Payroll
Bank transactions
Receipts
Equipment
Loans
Taxes
Owner contributions
Business withdrawals

You should also monitor your monthly cash flow.

A business can have strong sales and still fail because it does not have enough cash to pay rent, employees, suppliers, taxes, and other expenses.

Consider working with a California accountant or bookkeeper if your business has complicated tax or payroll requirements.

20. Build Your Business Around California Customers

Registering your company is only the beginning.

Your next challenge is finding customers.

Depending on your business, your marketing strategy could include:

Google Search
Local SEO
Google Business Profile
Social media
Email marketing
Paid advertising
Content marketing
Partnerships
Networking
Referral marketing
Events
Influencer marketing

If your business serves a particular city, focus your website and marketing on that location.

For example, a local cleaning company may target searches around Los Angeles or San Diego, while a software company may target customers throughout California and the wider U.S.

How Much Money Do You Need to Start a Business in California?

There is no single amount that every entrepreneur needs.

A freelance consultant working from home might start with a relatively small budget. A restaurant, construction company, retail store, manufacturing business, or healthcare company could require a much larger investment.

Your startup budget should include:

Expense What to consider

Business formation State filing and professional fees

Licences Local and industry-specific requirements

Premises Rent, deposit and utilities

Equipment Computers, machinery, furniture or tools

Website Domain, hosting and development

Marketing Advertising, branding and content

Insurance Industry-specific coverage

Accounting Accountant or bookkeeping costs

Employees Salaries, payroll taxes and benefits

Taxes Federal and California obligations

Inventory Products and supplies

Working capital Money needed to cover early expenses

For an LLC, remember that the California $800 annual LLC tax can be a recurring cost for businesses subject to it.

The most important question is not simply:

“How much does it cost to register my business?”

Instead, ask:

“How much money do I need to operate until the business generates consistent revenue?”

Can a Foreigner Start a Business in California?

Yes, foreign entrepreneurs can establish businesses in California, but business formation and immigration are separate issues.

A person can potentially establish a California business without automatically receiving permission to live and work in the United States.

If you are outside the U.S. and want to move to California to operate your company personally, you should investigate the appropriate immigration and work-authorisation requirements before making major financial commitments.

You may also need to consider:

Federal tax requirements
California tax requirements
EIN requirements
Banking
Business structure
Ownership
Immigration status
Work authorization

For complicated international situations, professional legal and tax advice is advisable.

Common Mistakes to Avoid

Starting a California business becomes much easier when you know what mistakes to avoid.

Choosing a business structure too quickly

Do not automatically choose an LLC or corporation simply because another entrepreneur did.

Consider taxes, liability, ownership, investment, administration, and your long-term plans.

Ignoring local requirements

Registering with the California Secretary of State does not necessarily mean that you have every city, county, industry, zoning, or professional permit you need. California specifically advises businesses to check local and agency requirements.

Underestimating California taxes

Do not rely solely on revenue to assess profitability.

Include federal taxes, California taxes, sales tax responsibilities (if applicable), payroll expenditures, and regular business expenses.

Forgetting the LLC annual tax

If you form an LLC, understand the California annual tax before you register. The standard annual LLC tax is currently $800 for entities subject to it.

Mixing personal and business finances

Use separate accounts and maintain organized records from the beginning.

Hiring employees without understanding California rules

California has extensive employment requirements. Understand wages, payroll taxes, worker classification, reporting, workplace rules, and other obligations before hiring.

Signing a lease too early

Before committing to a place, confirm its zoning, permits, business-use limitations, and estimated operating costs.

Focusing only on registration

A registered business is not automatically a successful business.

Your real work begins when you need to attract customers, manage expenses, deliver your product or service, and generate consistent cash flow.
