Starting a business in California involves multiple filings and fees across state and local agencies. The Secretary of State (SOS) handles entity formation (LLC: $70, Corp: $100), while the Franchise Tax Board (FTB) collects the $800 annual minimum franchise tax. You'll also need: an EIN from the IRS, a city business license ($50-$500/year depending on city), a seller's permit from the CDTFA (free), and a Statement of Information every 2 years ($20 for LLCs, $25 for Corps). This calculator totals your first-year and ongoing business registration costs.

Frequently Asked Questions
How much does it cost to register a business in California?
Minimum first year: LLC formation ($70 SOS) + $800 franchise tax + city business license ($50-$500) = ~$920-$1,370. Corporation: $100 SOS + $800 franchise tax + city license = ~$950-$1,400. Ongoing: $800/year + city license + $20-$25 SOI.
What is a Statement of Information?
A biennial filing with the CA Secretary of State listing your LLC/Corp's managers, agents, and address. LLCs: $20, Corporations: $25. Due within 90 days of formation, then every 2 years (LLCs) or annually (Corps). Late filing: $250 penalty.
Do I need a city business license in California?
Most California cities require a business license regardless of business type. Costs vary: LA ($101-$340/year based on gross receipts), SF ($110 + gross receipts tax), San Diego ($34 flat). Some home-based businesses need a home occupation permit.
What is the CDTFA seller's permit?
If you sell taxable goods in CA, you need a seller's permit from the CA Department of Tax and Fee Administration. It's free to obtain. You'll collect sales tax (7.25% base + district taxes) and remit it quarterly or monthly.
Can I form a business in another state to avoid CA fees?
You can form in Delaware/Nevada/Wyoming, but if you 'do business' in CA, you must register as a foreign entity and still pay the $800 franchise tax. You'd actually pay MORE: formation fees in the other state PLUS CA foreign registration.
Important Information for California Residents

This tool is designed for informational and educational purposes. While we strive for accuracy using official California Department of Taxation data, the results should be used as estimates for planning purposes only.
