Learning how to start business in California is one of the best decisions any entrepreneur can make.
California is home to more than 99.9 percent of businesses that are small businesses, and as of 2024, 47.1 percent of state employees work for small businesses.
The Golden State offers an enormous customer base, access to investors, and world-class infrastructure.
But it also comes with specific rules, fees, and regulations that every new business owner needs to understand before launching.
This complete guide covers everything you need to know about how to start business in California in 2026, with the latest facts and updated rules.
Why California Is a Great Place to Start a Business
Before diving into how to start business in California, it is worth understanding why so many entrepreneurs choose this state.
California has a strong venture capital environment. If your business idea is new and can expand, you are more likely to find investors in California than in many other parts of the country.
California is home to numerous industry clusters, including tech in Silicon Valley and entertainment in Los Angeles. This concentration of businesses creates valuable networking opportunities for startups seeking partnerships, mentorship, or talent.
The state also has one of the largest economies in the world, giving businesses access to millions of potential customers from day one.
Step 1: Validate Your Business Idea
The very first step in how to start business in California is making sure your idea actually works.
Before taking steps to start a small business in California, focus on whether your business idea actually solves a problem that people need help with and will spend money on.
The goal is to establish proof that people are willing to pay for what you are offering. Many founders rush into registration before confirming demand, which leads to unnecessary costs and stalled momentum.
Talk to potential customers. Test your product or service on a small scale. Make sure there is a real market before you spend money on registration and setup.
Step 2: Write a Business Plan
Every successful approach to how to start business in California begins with a solid business plan.
A business plan is a blueprint of every aspect of your business. Sales, marketing, advertising, promotion and location are just some of the categories to consider when creating a plan.
Having a business plan is also often required as part of the application process for obtaining a business loan. So if you know you are going to need funding, set yourself up for success by having a thoughtful business plan ready to share.
Your business plan should include an executive summary, a description of your product or service, your target market, your competition analysis, your marketing strategy, and your financial projections.
Step 3: Choose Your Business Structure
One of the most important decisions in how to start business in California is choosing the right structure.
Here is a comparison of the main options:
| Business Structure | Personal Liability | Tax Treatment | Best For |
|---|---|---|---|
| Sole Proprietorship | Full personal liability | Pass-through | Solo freelancers |
| Partnership | Personal liability shared | Pass-through | Two or more owners |
| LLC | Limited personal liability | Pass-through | Most small businesses |
| Corporation | Limited personal liability | Corporate tax | Larger businesses seeking investors |
LLC offers liability protection and simple taxes for most small businesses.
Corporations are a separate legal entity from the owner. Corporations often have investors and may even offer stock.
For most people learning how to start business in California, an LLC is the most practical and popular choice because it protects your personal assets while keeping taxes simple.
Step 4: Choose and Register Your Business Name
Choosing the right name is a key part of how to start business in California.
You will need to do this through the California Secretary of State. The organization offers a business entity name search tool. Use it to help you determine if the name you are considering is available. If it is, be sure to reserve it. You have 60 days to do so after you complete the Name Reservation Request Form from the website.
The California Secretary of State’s new BizFile Online portal makes the name reservation process fast and easy. You can search and reserve a name online in as little as 5 to 10 minutes.
If you are operating under a name that is different from your legal business name, you will need to file a doing business as (DBA) name.
If you want extra protection for your brand name, consider doing a federal trademark search through the USPTO website.
Step 5: Register Your Business with the State
Registering your business officially is a critical step in how to start business in California.
If you are forming an LLC or corporation, you will file with the California Secretary of State. For an LLC, it is the Articles of Organization. For a corporation, it is the Articles of Incorporation. Information required includes your business name, address, and the names of owners or directors.
Important: Statement of Information Deadline
California limited liability companies must file either Form LLC-12 Statement of Information or Form LLC-12NC Statement of Information No Change every two years with the Secretary of State. The filing fee for both form types is $20 and can be filed online, by mail, or in person.
One thing many new business owners miss is that the first Statement of Information must be filed within 90 days of registration. The California Secretary of State imposes a $250 penalty if you do not file your Statement of Information.
Mark this deadline in your calendar immediately after registering to avoid an unnecessary $250 fine.
Step 6: Get Your EIN from the IRS
Getting an Employer Identification Number is a simple but essential part of how to start business in California.
An EIN is a nine-digit number the IRS uses to identify your business for tax purposes. You will need one to file payroll taxes and federal tax returns, open a business bank account, and apply for loans. You can apply for a free EIN through the IRS website.
If your LLC has more than one owner, or if it will have employees, then you need an EIN. You can get a free EIN number through the Internal Revenue Service.
Getting your EIN is free and takes just a few minutes online at IRS.gov.
Step 7: Obtain Business Licenses and Permits
One of the most complex parts of how to start business in California is navigating the licensing requirements.
These steps will vary according to the type of business you intend to start and the county and city in which the business will be located. Therefore be sure to check specific rules and regulations within the county and city in which you want to conduct business, and any other agency requirements regarding zoning, licensing, employment, permits and taxes.
A seller’s permit is required if you are selling taxable goods or services, and certain professions such as contractors, cosmetologists, and healthcare providers require specific licenses to operate. The California Governor’s Office of Business and Economic Development provides a CalGold permit assistance tool to help you determine the necessary licenses and permits.
Here are common licenses and permits you may need:
| License or Permit Type | Who Needs It | Where to Apply |
|---|---|---|
| Seller’s Permit | Anyone selling taxable goods | California CDTFA |
| Business License | Most businesses | City or county office |
| Health Permit | Restaurants and food businesses | Local health department |
| Contractor License | Construction businesses | California CSLB |
| Professional License | Doctors, lawyers, cosmetologists | Relevant state board |
2026 Update on Online Sales Tax:
If you are selling online, California follows the Wayfair economic nexus rules. The California Department of Tax and Fee Administration has fully digitalized the registration and compliance process for online sellers in 2026. Any business making more than $500,000 in sales to California customers must register and collect sales tax regardless of where the business is physically located.
Step 8: Register for State Taxes and Understand the Franchise Tax
Taxes are an unavoidable part of how to start business in California.
If you have employees in the state, you will need to register for employer taxes, including unemployment insurance tax and employee withholding tax, through the California Employment Development Department’s e-Services for Business portal.
Important 2026 Franchise Tax Update:
Starting in 2024, California exempts newly formed or newly registered LLCs, LPs, and corporations from the $800 minimum franchise tax for their first taxable year. This exemption is still active for entities formed in 2026. If you form a new California LLC in July 2026, you owe $0 franchise tax for your first taxable year. The $800 kicks in for the second year.
This first-year exemption is a significant saving for new business owners and one of the best reasons to start your business in California right now.
However, there is an important warning. Even if your LLC is completely inactive with no revenue, no transactions, and no employees, you still owe $800 per year unless you formally dissolve or cancel the LLC with the California Secretary of State.
Also note that LLCs with total income exceeding $250,000 may be required to pay an additional fee based on their total income from California sources.
Step 9: Open a Business Bank Account
Opening a dedicated business bank account is an essential step in how to start business in California.
There are many benefits for opening a business bank account, including protection from liability, a more professional look, and the ability to make larger purchases in the name of your business.
A business bank account helps separate personal and business finances, which is required to maintain your California LLC’s corporate veil. A corporate veil protects your personal assets from creditors in potential lawsuits against your company.
You will need your EIN, your formation documents, and your business license to open a business bank account.
Step 10: Get Business Insurance
Insurance is a step that many new business owners skip when learning how to start business in California, and it can be a very costly mistake.
Having business insurance is a best practice for any business, even if you have the protections of an LLC or corporation.
Important 2026 Warning on Workers Compensation:
Workers compensation insurance is not just mandatory in California. Operating without it when you have even one employee is a criminal offense under California Labor Code Section 3700.5. You can face fines of up to $10,000 and possible jail time for non-compliance. Do not skip this step if you plan to hire anyone.
Common types of business insurance you should consider include general liability insurance, professional liability insurance, commercial property insurance, and workers compensation insurance.
Step 11: Set Up Your Finances and Accounting
Good financial management is the foundation of a successful business.
Whether you hire a professional accountant, make use of accounting software, or both, managing your finances smoothly from the get go is essential.
It is easy for your business and personal finances to get messy as an entrepreneur. You can prepare to start operating your business by opening a business bank account, applying for a business credit card, and possibly even contracting a business accountant.
Use accounting software like QuickBooks or Wave from day one. Keep every receipt. Track every expense. This makes tax time much simpler and protects you in case of an audit.
Step 12: Understand California Privacy Laws (CCPA) for Online Businesses
This is one of the most important steps for any business with an online presence when thinking about how to start business in California.
On January 1, 2026, new regulations under the California Consumer Privacy Act and the California Privacy Rights Act took effect, significantly expanding compliance requirements for businesses.
The CCPA applies to for-profit businesses meeting any of the following thresholds: annual gross revenue exceeding $26,625,000, or deriving 50 percent or more of annual revenue from selling or sharing personal information, or processing personal information of 100,000 or more California residents or households annually.
If your business meets any of these thresholds, you must comply with the CCPA. This means having a clear privacy policy, allowing customers to access and delete their data, and not selling customer data without consent.
The CPPA has finalized regulations addressing Automated Decision-making Technology, privacy risk assessments, and cybersecurity audits. The regulations became effective January 1, 2026.
Even if your business does not yet meet the CCPA threshold, it is best practice to have a proper privacy policy from day one.
Step 13: Secure Funding for Your Business
Funding is a reality that every entrepreneur faces when figuring out how to start business in California.
If you need to secure funding for your business, you have options for how to proceed. Consider personal savings and bootstrapping, and small business loans. The US Small Business Administration offers loan programs. Many California-based banks and credit unions also provide business financing to small businesses.
Here is a quick overview of the main funding options:
| Funding Source | Best For | Key Consideration |
|---|---|---|
| Personal Savings | Early stage businesses | No debt but limited funds |
| SBA Loans | Established small businesses | Requires good credit |
| Venture Capital | High growth tech startups | Requires equity sharing |
| Angel Investors | Early stage startups | Requires a strong pitch |
| Business Credit Cards | Day to day expenses | Watch interest rates |

Step 14: Build Your Team
If you plan to hire employees, there are additional steps in how to start business in California that you must follow.
Hiring employees means your business is growing. But it also comes with legal responsibilities you cannot ignore. Obtaining an EIN from the IRS is essential for hiring employees. Securing workers compensation insurance is mandatory in California.
You also need to register with the California Employment Development Department to handle payroll taxes and employee withholding. Make sure every employee fills out both federal Form W-4 and California Form DE-4 for state withholding.
