How to Form an LLC in California: Step-by-Step Guide

California is the biggest economy in the U.S., and forming an LLC here is one of the most common things I help people with. It's also one of the most expensive states to operate in — so you need to go in with your eyes open.

Here's exactly how to form a California LLC, step by step, with real costs and timelines. No fluff.

Step 1: Choose Your LLC Name

Your LLC name must be distinguishable from any existing business entity registered with the California Secretary of State. It must include "LLC," "L.L.C.," or "Limited Liability Company."

Search the California Secretary of State business search to check availability. A few rules:

• Can't include words like "bank," "trust," "insurance," or "corporation" (those imply a different entity type)
• Can't be identical or deceptively similar to an existing registered entity
• You can reserve a name for 60 days by filing a Name Reservation Request ($10 fee), but most people skip this and just file their Articles

Common Mistake #1

People check if the name is available with the state but forget to check for federal trademark conflicts. A name that's available at the state level can still get you a cease-and-desist letter if someone holds a federal trademark. Search the USPTO trademark database too.

Step 2: File Articles of Organization (Form LLC-1)

This is the main filing that actually creates your LLC. You'll submit Form LLC-1 to the California Secretary of State.

What you need:

• Your LLC name
• The street address of your LLC (P.O. boxes not accepted as principal address)
• Your registered agent's name and California street address
• Whether the LLC will be managed by one manager, more than one manager, or all members
• The organizer's name and signature

Filing fee: $70

Processing time: Online filing through bizfile is typically processed within a few business days. Paper filings take 5-7 business days for regular processing. Expedited processing is available for additional fees.

Common Mistake #2

Listing yourself as the registered agent and then not being available during business hours. The registered agent must be physically present at the listed California address during normal business hours to accept legal documents. If you work from home and are always there, fine. If not, use a professional registered agent service.

Step 3: Pay the California Franchise Tax ($800 Minimum)

Here's the part that catches people off guard. California imposes an $800 annual franchise tax on every LLC, regardless of income. Even if your LLC makes $0, you owe $800 per year.

Your first payment is due by the 15th day of the 4th month after your LLC is formed. So if you form your LLC on January 15, your first $800 is due by May 15.

LLCs that make over $250,000 in annual gross revenue also pay an additional fee ranging from $900 to $11,790, depending on income brackets.

Important note: California offers a first-year franchise tax exemption for new LLCs in their first taxable year. This is a significant savings, so time your formation accordingly if you're close to year-end.

Step 4: File Statement of Information (Form LLC-12)

Within 90 days of forming your LLC, you must file a Statement of Information (Form LLC-12) with the Secretary of State.

Filing fee: $20

This form lists your LLC's managers or members, the agent for service of process, and your principal business address. After the initial filing, you'll need to refile this every two years.

Common Mistake #3

Forgetting to file this within 90 days. Miss the deadline and you'll face penalties and potentially have your LLC suspended. Put it on your calendar the day you file your Articles.

Step 5: Create an Operating Agreement

California law doesn't require you to file an Operating Agreement with the state, but you absolutely need one. This document defines:

• How the LLC is managed (member-managed vs. manager-managed)
• How profits and losses are divided
• What happens if a member wants to leave
• How disputes are resolved
• Voting rights and procedures

Even single-member LLCs need an Operating Agreement. It reinforces the separation between you and your LLC, which strengthens your liability protection. Without it, a court might argue there's no real separation between you and the business.

Step 6: Get an EIN (Employer Identification Number)

An EIN is like a Social Security number for your business. You'll need it to:

• Open a business bank account
• File business taxes
• Hire employees
• Apply for business licenses and permits

The good news: it's free. Apply directly on the IRS website and you'll get your EIN immediately.

Total Costs Summary

• Articles of Organization: $70
• Statement of Information: $20
• Annual Franchise Tax: $800 (first-year exemption may apply)
• EIN: Free
• Registered Agent (if using a service): $99-$299/year
• Total first year: approximately $190-$890+ depending on franchise tax exemption and agent choice

Timeline

If you file everything online, you can have your California LLC up and running — with Articles filed, EIN in hand, and a business bank account open — within 1-2 weeks. The bottleneck is usually the Secretary of State's processing time.
