California business formation overview
If you're forming a business in California, the four most common entity types are the LLC (most popular for solo founders and small partnerships), the C-Corporation (used by venture-funded startups), the S-Corporation (a tax election available to LLCs and corporations meeting IRS rules), and the DBA ("doing business as", a trade-name registration for sole proprietors and existing entities). Each has its own filing fee, ongoing report cycle, and tax treatment in California.
The cheapest path to a registered business in California is the LLC at $70 for the Articles of Organization. A C-Corporation costs $100 for the Articles of Incorporation, and a DBA registration is $26. After formation you'll have ongoing obligations: an annual report ($20, biennial), a registered agent with a physical California address, and any applicable franchise or income tax: $800 minimum annual.
