How to Start a Business in California

Your complete 2026 guide to business registration, state taxes, licenses, and key industries in California.

California's dynamic economy and diverse business landscape make it an attractive destination for entrepreneurs. Whether you're launching a startup, relocating an existing business, or expanding operations, understanding the state's business formation requirements is essential for success. This guide covers the fundamental steps to establish a legally compliant business in California.

Choosing the right business structure is your first critical decision. California recognizes several entity types, each with distinct advantages. A sole proprietorship is the simplest option, requiring minimal formalities and allowing you to operate under your own name or a fictitious business name. Partnerships, both general and limited, allow two or more individuals to share ownership and profits while potentially offering different levels of liability protection. Limited liability companies, or LLCs, have become increasingly popular because they combine the liability protection of corporations with the tax flexibility and operational simplicity of partnerships. Corporations, whether S-Corps or C-Corps, are distinct legal entities offering strong liability protection but requiring more formal governance, record-keeping, and compliance obligations.

Once you've selected your business structure, you'll need to register with the California Secretary of State, which serves as the primary filing agency for business entities. The process varies slightly depending on your chosen structure. For LLCs and corporations, you'll file Articles of Organization or Articles of Incorporation with the Secretary of State, paying the associated filing fee. Check the current fee at the Secretary of State website, as these fees periodically change. Most entities must also appoint a registered agent who maintains a physical address in California and is authorized to receive legal documents on behalf of your business. This registered agent can be you, an employee, or a professional registered agent service.

Understanding California's tax obligations is crucial for maintaining compliance and avoiding penalties. California imposes a state income tax on business profits, with rates varying based on your business structure and income level. Unlike some states, California has no flat state income tax exemption for businesses, so even newly formed entities may owe taxes depending on their structure. Additionally, California requires businesses that sell tangible goods to collect and remit sales tax. The state sales tax rate varies by location but is among the highest in the nation when combined with local taxes. You'll need to register with the California Department of Tax and Fee Administration to obtain a seller's permit before conducting taxable sales.

Businesses in California are also subject to the Franchise Tax Board's annual filing requirements. Depending on your entity type, you may owe annual franchise taxes or gross receipts taxes. Most LLCs and corporations must file annual returns, and some must pay minimum taxes even if they generate no income. These obligations exist regardless of profitability, so budgeting for these ongoing costs is essential.

Beyond state registration and taxes, securing appropriate licenses and permits is mandatory. Most businesses need a general business license from their city or county, though requirements and processes vary by location. Beyond general licensing, industry-specific permits and regulatory approvals may be necessary. Restaurants require health permits, construction companies need contractor licenses, and professional service providers like accountants and attorneys must maintain active professional licenses from their respective state boards. Some industries, such as banking, insurance, and real estate, operate under particularly stringent regulatory frameworks with their own licensing agencies.

California's economy encompasses diverse and thriving sectors. Technology continues to dominate, particularly in the Bay Area and Southern California, with software development, biotechnology, and clean energy attracting significant investment and talent. Entertainment, media, and aerospace remain major industries, especially in the Los Angeles area and surrounding regions. Healthcare, agriculture, manufacturing, and professional services also represent substantial economic segments. Additionally, California actively supports emerging industries through various programs and incentives, particularly in renewable energy, electric vehicles, and advanced manufacturing.

The state's major metropolitan areas offer robust business infrastructure and resources. Cities like Los Angeles, San Francisco, San Diego, and Sacramento host extensive networks of business organizations, entrepreneurial support centers, and government resources tailored to business development. Smaller cities throughout the state also provide accessible local permit processing and business support services.

Finally, consider working with an accountant and attorney experienced in California business law. Their expertise can help you navigate tax obligations, structure your entity optimally, and ensure compliance with evolving regulations. This investment often pays dividends by helping you avoid costly mistakes and identify opportunities for tax efficiency.

Starting a business in California requires careful attention to registration, taxation, and licensing requirements. By systematically addressing each of these elements, you'll establish a solid legal and financial foundation for your entrepreneurial venture.
