Step-by-Step California Business Formation Process

Step 1: Choose Your Business Structure
Before starting your business, you need to decide which type of entity suits your goals. Here’s a breakdown of the most common structures:
Business Structure | Description | Tax Implications in Colorado |
---|---|---|
LLC (Limited Liability Company) | Protects personal assets, flexible management | Pass-through taxation; subject to LLC fee |
Corporation | Separate entity; can issue stocks | Double taxation: corporate & personal income tax |
Partnership | Shared ownership, simple structure | Pass-through taxation, personal liability for partners |
Sole Proprietorship | Single-owner, simplest form of business | Pass-through taxation; income taxed as personal income |
Nonprofit | Organization focused on charitable, educational, or other public-benefit purposes | Tax-exempt status if approved by IRS; donations are tax-deductible |
LLP (Limited Liability Partnership) | Partnership with liability protection for partners | Pass-through taxation; personal liability protection for partners in certain circumstances |
Step 2: Name Your Business
In California, all business names must be unique, and they cannot infringe on any existing trademarks. You can easily check name availability through the California Secretary of State’s website.
Once you’ve chosen a name, you’ll likely need to file a Fictitious Business Name Statement (also known as a fictitious business name or DBA (“Doing Business As”), especially if you’re using a name that doesn’t directly match the legal name of your business entity [1].
It’s also smart to conduct a trademark search on the U.S. Patent and Trademark Office’s (USPTO) website to identify any trademarks that might already be associated with your name.
Step 3: Register Your Business
Once you have a name, it’s time to register your business with the California Secretary of State.
The primary document you'll file is your Articles of Incorporation if you're forming a corporation, or Articles of Organization if you're forming an LLC in California.
However, other business types have specific documents [2]:
- LPs (Limited Partnerships): File a Certificate of Limited Partnership with the Colorado Secretary of State.
- LLPs (Limited Liability Partnerships): File a Statement of Registration to officially register your LLP.
- Nonprofits: File Articles of Incorporation for a Nonprofit Corporation, and later apply for federal tax-exempt status with the IRS using Form 1023 [3].
- Sole Proprietorship: You don’t need to file formation documents, but you may need to register a Doing Business As (DBA) name with your county if you're using a business name other than your own.
- Partnerships: You don’t need to file with the state, but it’s recommended to create a Partnership Agreement to outline the roles and responsibilities of each partner.
Be aware that if you’re forming an LLC, the California Secretary of State requires an annual minimum franchise tax of \$800, which is due each year, even if you don’t earn any income.
California law also requires all business entities to designate a Registered Agent (also called an Agent for Service of Process) who can receive legal documents on behalf of your business.
The registered agent must be a California resident with a physical street address in the state and be available during standard business hours.
You can serve as your own registered agent if you meet these requirements, or hire a professional registered agent service.
Step 4: Write an Operating Agreement
An Operating Agreement is a legal document that outlines how your business will be run, especially important for LLCs and partnerships.
While California doesn't legally require an Operating Agreement for LLCs, it's highly recommended as it establishes management structure, ownership percentages, profit and loss distribution, and procedures for adding or removing members.
In California, without an Operating Agreement, your LLC will be governed by default state laws, which may not align with your business goals.
For partnerships, a Partnership Agreement serves a similar purpose and should outline each partner's roles, responsibilities, and profit-sharing arrangements.
Step 5: Get Federal and California State Tax IDs
To pay taxes and hire employees, small business owners need to get a Federal Employer Identification Number (EIN) from the Internal Revenue Service (IRS).
California also requires a state tax ID for sales tax collection and other state taxes.
Key California Tax Information:
- Sales Tax: California has a base state sales tax rate of 6.0%, but the total sales tax rate ranges from 7.25% to over 10% when including local taxes, making it one of the highest in the nation.
- Personal Income Tax: California has nine tax brackets ranging from 1% to 12.3% for regular income, with an additional 1% Mental Health Services Tax on income over \$1 million.
- Corporate Income Tax: California corporations pay an 8.84% flat rate on net income, plus a minimum franchise tax of \$800 annually.
- LLC Tax: LLCs pay a minimum annual franchise tax of \$800, plus an additional fee based on gross receipts ranging from \$900 to \$11,790 for LLCs with receipts over \$250,000.
Step 6: Open a Business Bank Account
To separate your personal and business finances as a sole proprietorship, open a business bank account. You’ll need documentation such as your business registration, Employer Identification Number, a valid ID, and a comprehensive business plan if required.
Step 7: Obtain Required Licenses and Permits
Depending on your business type and location, you may need a general business license and industry-specific permits.
If you also plan to sell goods in California, you need to register with the California Department of Tax and Fee Administration (CDTFA) to get a seller's permit.
Step 8: Get Business Insurance
California requires workers' compensation insurance for businesses with employees, and other types of insurance like general liability or professional liability may be necessary.
Consult with local agents to understand the local zoning regulations and the coverage you need to ensure your business stays protected.
