Dreaming of launching your own business in California? With its booming economy, innovation hubs, and 4.1 million small businesses, the Golden State is a land of opportunity. But where do you start? This step-by-step guide breaks down everything, from registering your business to securing funding, so you can launch successfully.

Starting a business in California is an appealing prospect for many entrepreneurs due to the state’s large economy, diverse population, and culture of innovation.
With 4.1 million small businesses operating as of 2023, employing over 7.5 million people, California continues to be a thriving environment for new ventures.
However, navigating the process requires careful planning, regulatory compliance, and an understanding of the local market.
11 steps to start a business in California
1. Develop a business idea
Every business begins with an idea. Whether it’s in electric vehicle infrastructure, renewable energy, or sustainable materials, identifying a commercially viable concept suited to California’s market is essential. Research your target audience, understand industry trends, and refine your offering to stand out in a competitive landscape.
2. Choose and register a business name
Your business name is central to your brand identity. Check its availability via the California Secretary of State’s Business Search tool. If you’re not using your legal name, file a “Doing Business As” (DBA) with your county. You may also consider trademarking the name to protect it at the national level.
3. Write a business plan
A detailed business plan helps structure your ideas and is often necessary when seeking funding. Include key components such as a company description, market analysis, marketing strategy, financial projections, and operational structure. This document is not just for investors—it also serves as a roadmap for your growth.
4. Select a business structure
Choose a legal structure that suits your business needs:
- Sole proprietorship – Simple to set up, but offers no separation between personal and business liabilities.
- Partnership – Shared ownership and responsibility; each partner is personally liable.
- Limited Liability Company (LLC) – Offers personal liability protection and flexible tax options.
- Corporation (C or S Corp) – More formal structure with liability protection; suitable for raising investment.
- Limited Liability Partnership (LLP) – Similar to partnerships but with limited liability for each partner.
5. Register the business
File the necessary formation documents with the California Secretary of State:
- LLCs file Articles of Organisation
- Corporations file Articles of Incorporation
Most entities must also submit an initial Statement of Information. You will need to appoint a registered agent, a person or business in California authorised to receive official documents on your behalf.
6. Obtain an EIN
An Employer Identification Number (EIN) from the IRS is needed to open a business bank account, hire employees, and file taxes. This is similar to a personal National Insurance number but for businesses. You can apply online through the IRS website.
7. Register for taxes
Businesses in California may be subject to several types of taxes:
- Franchise Tax – An annual minimum tax of $800 for most business entities.
- Sales Tax – If selling goods, register with the California Department of Tax and Fee Administration (CDTFA).
- Payroll Taxes – Employers must register with the Employment Development Department (EDD) to manage unemployment insurance, disability insurance, and income tax withholding.
8. Apply for licences and permits
Depending on your business type, you may require state, local, or federal permits.
- Seller’s permit for retail businesses.
- Professional licences for regulated industries.
- Local business licences issued by city or county agencies.

9. Set up business banking
Open a separate business bank account to keep personal and business finances distinct. You may also wish to apply for a business credit card and consider hiring an accountant to manage taxes and financial planning efficiently.
10. Secure insurance
Insurance helps protect your business from risks. Depending on your industry, consider:
- General Liability Insurance
- Professional Indemnity Insurance
- Workers’ Compensation Insurance (mandatory for businesses with employees)
The California Department of Insurance offers guidance on which types of insurance may apply to your business.
11. Market your business
Marketing is crucial for business success. Create a brand identity, develop a website, and use social media, email campaigns, and advertising to reach customers. Conduct market research and use tools like SWOT analysis to guide your marketing decisions.
