What It Takes to Start a Business in California
Forming an LLC in California costs $70 for the Articles of Organization, plus an $800 annual franchise tax that applies to every LLC and corporation regardless of revenue. You will also need to file a Statement of Information with the California Secretary of State within 90 days of formation for $20.
Beyond state filings, most California cities require a local business license or tax certificate. Plan for at least $890 in mandatory state costs during your first year before any local fees or insurance.

Pro Tip
Write a Business Plan
Draft a one-page lean plan first, then expand it into a full document if you need bank financing or SBA loans. Lenders and the SBA require revenue projections, a competitive analysis, and a clear use-of-funds breakdown.
Follow our step-by-step business plan guide to build a plan that satisfies both investors and loan officers.
Pro Tip
Choose Your Business Structure in California
Most founders in California choose an LLC because it combines personal liability protection with pass-through taxation. Filing an LLC costs $70 online at the California Secretary of State.
The four main structures are sole proprietorship, LLC, S-Corp, and C-Corp. Compare all four structures in the table below before deciding, or read our full California LLC formation guide.

Business Structure Comparison — California
Full comparison guide| Structure | California Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | $26 (DBA) | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $70 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$70 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $100 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in California pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full California LLC guide →
Choose and Register Your Business Name
Search the California Secretary of State business search to confirm your desired name is not already taken. Your LLC name must include "LLC" or "Limited Liability Company" as a designator.
Reserve your name for 60 days by filing a Name Reservation Request for $10. If you operate under a name different from your registered entity name, file a DBA (Fictitious Business Name Statement) with your county clerk for roughly $10 to $100 depending on the county.
Pro Tip
Check California Business Name Availability
Search the official California Secretary of State database before you file.
Register Your Business with the State
File your Articles of Organization with the California Secretary of State online for $70. Standard processing takes 3 to 5 business days.
After approval, you will receive a stamped copy of your Articles and an entity number. You must designate a registered agent with a physical California address during filing.

Open a Business Bank Account
Bring your EIN confirmation letter, stamped Articles of Organization, a government-issued photo ID, and your LLC operating agreement to the bank. Separating personal and business finances is critical for maintaining your LLC's liability protection.
Compare fee structures and features in our best business bank accounts guide before choosing.
Pro Tip
Set Up Accounting and Understand California Taxes
California has a progressive state income tax ranging from 1% to 13.3%, the highest top marginal rate in the nation. LLCs taxed as pass-through entities report business income on your personal California return.
Every LLC also owes a minimum $800 annual franchise tax to the Franchise Tax Board (FTB), due by the 15th day of the 4th month after your tax year begins. LLCs with gross revenue over $250,000 pay an additional fee ranging from $900 to $11,790.
Set up quarterly estimated tax payments if you expect to owe $500 or more in state taxes. Track everything from day one using cloud accounting software from our recommended accounting tools list.
Pro Tip
Important
Get Business Insurance in California
California requires workers' compensation insurance for every business with at least one employee, with no exceptions. Penalties for noncompliance can reach $100,000 or more, plus criminal charges.
General liability insurance is the baseline policy for all businesses, typically costing $400 to $1,500 per year. Compare policy options in our best business insurance guide.

Pro Tip
