California doesn't mess around when it comes to business regulations—but there's a reason 4.1 million small businesses choose to operate here anyway.
The Golden State runs the world's 5th largest economy, where small businesses pull in over $1.8 trillion annually, and your potential customers have spending power that most countries would kill for.
Sure, you'll face that infamous $800 franchise tax and navigate complex employment laws, but you're also tapping into markets from Silicon Valley tech to Central Valley agriculture, where a single successful café in San Francisco can outperform entire shopping centers in other states.
8 Steps to Starting a Business in California
- Choose your business structure
- Register your business name
- Get your required licenses and permits
- Register for taxes
- Get workers' compensation insurance
- Open a business bank account
- Understand employment laws
- Plan your ongoing compliance
1. Choose Your Business Structure
California offers several business entity options, each carrying distinct implications for liability protection, tax obligations, and operational complexity.
LLC Formation: Articles of Organization cost $70 and process within 5-15 business days online. LLCs provide personal asset protection while maintaining operational flexibility and favorable tax treatment options. Perfect for most small businesses planning to employ hourly workers.
Corporation Formation: Articles of Incorporation cost $100 with the same processing timeframe as LLCs. Corporations offer the highest liability protection but require more administrative compliance including annual meetings and periodic state reports.
Partnership Formation: General partnerships need no state registration and minimal administrative burden, but partners face unlimited personal liability for business debts and obligations. Limited partnerships require $70 filing fees and offer liability protection for limited partners.
Sole Proprietorship: The simplest structure requires no state registration, but you'll face personal liability exposure for all business activities. Works best for single-owner businesses with minimal risk exposure.
2. Register Your Business Name
Your business name registration involves both legal compliance requirements and practical branding considerations. California businesses must ensure their chosen name complies with state regulations and doesn't conflict with existing entities.
Name Availability Search: Search the California Secretary of State's business entity database to verify your name is available within your chosen business structure. Also conduct trademark searches through the US Patent and Trademark Office to avoid intellectual property conflicts.
DBA Registration: For businesses operating under names different from their legal entity names, California requires fictitious business name registration. County filing fees range from $26 in Los Angeles County to $44 in Sacramento County.
Publication Requirements: DBA statements must be published once weekly for four consecutive weeks in newspapers of general circulation. This adds $40-$100 to your total DBA costs depending on your county's newspaper rates.
Domain Name Considerations: Secure matching domain names to maintain brand consistency and support future marketing efforts. The interconnected nature of business naming, legal registration, and digital presence requires coordinated planning.
3. Get Your Required Licenses and Permits
California's licensing requirements create a multilayered system involving federal, state, and local jurisdictions with specific requirements based on business type and location.
Nearly every city requires basic business licenses for commercial operations.
City Business Licenses: Los Angeles charges $15-$1,000 depending on business type, San Francisco ranges $91-$850, San Diego runs $34-$500, and Sacramento charges $75-$500. Each municipality maintains its own licensing procedures, fees, and renewal schedules.
State Professional Licenses: California requires professional licenses for healthcare, construction, cosmetology, and real estate services. These licenses often involve education requirements, examinations, and ongoing continuing education obligations.
Industry-Specific Permits: Food businesses must obtain health permits from local health departments, retail stores need seller's permits for sales tax collection, and businesses serving alcohol require ABC licenses from the state.
Home Occupation Permits: Home-based businesses often require special permits to ensure compliance with residential zoning requirements and minimize neighbor impact concerns.
4. Register for Taxes
California's tax obligations include multiple registration requirements with both state and federal agencies. The California tax system includes income taxes, franchise taxes, sales taxes, and employment taxes, each with distinct registration requirements.
Federal EIN Application: Apply for your Employer Identification Number through the IRS website for free. The EIN serves as your business's tax identification number and enables opening business bank accounts and filing tax returns.
California Franchise Tax: Every LLC and corporation owes $800 minimum franchise tax annually, due by the 15th day of the fourth month after filing with the Secretary of State. LLCs also face additional income-based fees ranging from $900 to $11,790 depending on California gross receipts.
Seller's Permit: Businesses selling goods must register with the California Department of Tax and Fee Administration to collect and remit sales tax. The registration may require security deposits for certain business types.
Employment Tax Registration: Businesses hiring employees must register with the Employment Development Department within 15 days of meeting wage thresholds. This establishes accounts for payroll tax collection and unemployment insurance obligations.
5. Get Workers' Compensation Insurance
Workers' compensation represents a fundamental requirement for California employers, mandating coverage for businesses with even one employee. The state defines employees broadly, making coverage requirements applicable to most business operations with staff.
Coverage Requirements: California requires minimum coverage levels of $100,000 per occurrence, $100,000 per employee, and $500,000 total policy value. Coverage must be maintained continuously throughout business operations with employees.
Penalty Risks: Failure to maintain workers' compensation coverage results in significant penalties, including fines up to $100,000 and potential criminal charges. The state actively monitors compliance and pursues violations aggressively.
Employee Information Requirements: Employers must provide employees with information about workers' compensation rights and maintain required workplace postings. When injuries occur, claim forms must be provided within one business day.
Medical Treatment Authorization: Employers must authorize up to $10,000 in immediate medical treatment for workplace injuries while claims are being processed and evaluated.
6. Open a Business Bank Account
Opening a dedicated business bank account separates your personal and business finances while establishing banking relationships for future credit needs.
Most banks require specific documentation before account opening.
Required Documentation: You'll need your federal EIN, business formation documents (Articles of Organization/Incorporation), and business license or permit. Some banks also require business plans or financial projections for new accounts.
Account Selection Considerations: Compare monthly fees, transaction limits, online banking features, and local branch availability. Many small businesses benefit from business checking accounts with integrated merchant services for customer payments.
Banking Relationship Building: Establishing banking relationships early helps with future loan applications, merchant account setup, and business credit building. Consider banks that specialize in small business services and understand your industry.
Separate Business Credit: Using dedicated business accounts and credit cards helps build business credit scores separate from personal credit, enabling better financing options as you grow.
7. Understand Employment Laws
California's employment laws create extensive compliance obligations for businesses with employees, establishing some of the most worker-protective regulations in the United States. Requirements apply to businesses with as few as five employees for many regulations.
Worker Classification: California's AB5 legislation establishes strict criteria for independent contractor relationships through the ABC test. Misclassification can result in significant penalties, back pay obligations, and tax liabilities.
Wage and Hour Requirements: California's minimum wage exceeds federal requirements, with overtime obligations including time-and-a-half for work exceeding eight hours daily or forty hours weekly. Double-time requirements apply for extended work periods.
Leave Benefits: Businesses must provide at least 24 hours or three days of paid sick leave annually, with accrual requirements beginning from employment start dates. Additional leave benefits include family and medical leave and pregnancy disability accommodations.
Harassment Prevention Training: Mandatory for businesses with five or more employees requiring comprehensive programs covering prohibited conduct and complaint procedures. Training must include specific content standards and periodic renewal requirements.
8. Plan Your Ongoing Compliance
California business operations require continuous compliance monitoring and periodic reporting to maintain good standing with regulatory agencies. Ongoing compliance encompasses annual reports, tax filings, license renewals, and operational requirement adherence.
Annual State Reports: Corporations must file initial statements within 90 days of incorporation and subsequently file annual reports. LLCs must file statements of information biennially with updated business information.
License Renewal Requirements: Most local business licenses require annual renewal with updated information and fee payments. Professional licenses often involve continuing education requirements and periodic renewal applications.
Tax Compliance Schedules: Franchise tax payments occur annually, while sales tax filings may be required monthly, quarterly, or annually depending on sales volume. Employment taxes typically require quarterly filings and payments.
Beneficial Ownership Reporting: New federal requirements implemented in 2024 require corporations to file beneficial ownership information reports with FinCEN. New businesses must file within 30 days of formation.
How to Get a Business License in California?
Your California business licenses include city permits ranging from $15 in LA to $850 in San Francisco, plus state-specific permits that vary wildly by industry—from $200 health permits for restaurants to $5,000+ professional licenses for contractors.
Unlike states with simple statewide systems, California requires you to navigate 58 counties and 482 cities, each with their own rules, fees, and renewal schedules.
The good news? Most cities offer online applications, and you can operate while permits are pending in most jurisdictions.
- Los Angeles County Requirements: Business tax registration ranges $15-$1,000 based on your inventory levels, gross receipts, and employee count. The city processes most applications within 2-3 business days online, but specialized permits like health department approvals can take 2-4 weeks.
- San Francisco Bay Area Complexity: San Francisco charges $91-$850 depending on business type, while San Jose runs $35-$300, and Oakland ranges $30-$500. Each city requires separate applications even if you're operating regionally.
- San Diego and Orange County: San Diego's business tax certificates cost $34-$500, while most Orange County cities charge $50-$400 annually. These coastal markets often have additional zoning requirements for retail and food service businesses.
- Central Valley Affordability: Fresno charges $25-$150 for most business licenses, Sacramento runs $75-$500, and Stockton keeps fees under $200 for most small businesses. The region offers significant cost savings compared to coastal areas.
Pro Tip: Start your license applications 30-45 days before you plan to open. California's multi-jurisdiction system means delays are common, but the market opportunity makes the paperwork worth it.
What are the Best Cities to Start a Small Business in California?
The best California cities for small businesses are San Francisco (median income $126,000, tech ecosystem), Los Angeles (3.8 million population, entertainment industry), San Jose (Silicon Valley access, venture capital), and Sacramento (government contracts, lower costs).
Each market offers distinct advantages that can make or break your specific business model.
San Francisco Bay Area Premium Markets: San Francisco's $126,000 median household income means customers who'll pay premium prices for quality products and services.
Los Angeles Entertainment and Diversity: LA County's 3.8 million residents create massive market depth across every demographic. The entertainment industry generates unique B2B opportunities, while neighborhoods like Venice Beach support $300K+ annual food truck revenues.
Silicon Valley Tech Ecosystem: San Jose and Palo Alto offer access to venture capital, high-income tech workers, and B2B opportunities serving startups. Commercial costs are steep, but a single corporate catering contract can be worth $50K+ annually.
Sacramento Government Advantage: As California's capital, Sacramento offers steady government contracting opportunities, lower commercial rents ($1.50-$3.00/sq ft), and a stable customer base of state employees with consistent income.
How Much Money Do You Need to Start Your Business in California?
Starting a business in California costs $1,200-$15,000 depending on your industry, with the infamous $800 franchise tax hitting within your first year regardless of profitability.
The key difference from other states isn't just higher costs—it's that California's market potential can justify the investment if you plan correctly.
What are Your Required California Business Filing Fees and Processing Times?
Your required California business filing fees range $70-$100 for basic formation, but the real costs come from the $800 minimum franchise tax due within months of filing, plus county-specific DBA publication requirements ranging $40-$144.
Processing times run 5-15 business days online or 15-20 days by mail for state filings, but local permits can add weeks to your timeline.
- State Formation Costs: LLC Articles of Organization cost $70, Corporation Articles cost $100, and both process within 5-15 business days if filed online through the Secretary of State's website.
- DBA Publication Surprise: Beyond the $26-$44 county filing fee, you'll pay $40-$144 for required newspaper publication over four consecutive weeks. Los Angeles tends to be cheaper, while smaller counties often cost more.
- First-Year Tax Reality: The $800 franchise tax hits LLCs and corporations by the 15th day of the fourth month after filing. File in January, pay by April 15th. File in September, pay by December 15th.
- Professional Corporation Additions: Licensed professionals pay the same $100 filing fee but face additional regulatory requirements and often higher insurance minimums that can add $1,000-$5,000 to startup costs.
What Hidden Costs Should You Budget for Your California Business?
Your hidden costs include that $800 franchise tax ambush, plus LLCs with over $250K in California revenue face additional fees reaching $11,790 annually—costs that don't exist in most other states.
The regulatory complexity means you'll likely need professional help navigating requirements, adding $1,000-$3,000 in legal and accounting fees during your first year.
- Franchise Tax Escalation: LLCs pay $800 minimum, but owe additional fees based on California gross receipts: $900 (over $250K), $2,500 (over $500K), $6,000 (over $1M), up to $11,790 for businesses over $5M in revenue.
- Employment Law Compliance: California's strict labor laws mean higher legal risks. Employment practices liability insurance costs $400-$1,200 annually, while harassment prevention training runs $50-$200 per employee annually.
- Industry-Specific Surprises: Food businesses need health permits ($200-$1,000), construction requires contractor licenses ($300-$8,000), and any business serving alcohol needs ABC licensing ($300-$15,000+ depending on license type).
- Geographic Cost Variations: San Francisco requires additional permits for many businesses, LA has inventory-based fee structures, and coastal cities often mandate environmental compliance reviews costing $500-$2,000.
What are the Real Startup Costs Beyond Filing Fees in California?
Your real startup costs range $2,000-$50,000 beyond state filing fees, with the biggest variables being commercial rent (2x-5x higher than most states), workers' compensation insurance, and industry-specific equipment or inventory.
The difference from other states isn't just higher costs—it's that California's consumer spending power often justifies premium pricing that covers the extra investment.
- Commercial Real Estate Reality: San Francisco retail space costs $4-$8/sq ft monthly, LA runs $2-$5/sq ft, while Central Valley markets offer $1-$3/sq ft. Factor in California's triple-net lease structures and security deposit requirements.
- Equipment and Technology: Point-of-sale systems, commercial kitchen equipment, and professional tools cost 10-20% more in California due to energy efficiency requirements and seismic safety standards.
- Insurance Package Deals: General liability ($800-$2,000), workers' compensation ($500+ per employee), professional liability ($400-$1,500), and cyber liability ($300-$1,000) create annual costs of $2,000-$6,000+ for most small businesses.
- Marketing Launch Investment: California's competitive markets require stronger initial marketing. Budget $2,000-$10,000 for professional website, local SEO, social media setup, and initial advertising to establish market presence.
Pro Tip: Build a 6-month operating expense cushion beyond startup costs. California's higher cost of living means everything from utilities to employee wages will exceed national averages, but the market rewards quality with premium pricing.
What Support Resources Can You Access for Your California Business?
The support you can access includes free counseling through SCORE chapters in 30+ California cities, Small Business Development Centers at major universities like UCLA and UC Davis, plus California-specific programs like GO-Biz that other states don't offer.
The state's massive entrepreneur ecosystem means more mentorship and networking opportunities than you'll find anywhere else in America.

Tip: Leverage California's venture capital network even for non-tech businesses. Many VCs and angel investors provide mentorship and connections that can accelerate growth beyond traditional small business resources.
What's Your 30-Day Action Plan to Start Your California Business?
Your 30-day California action plan includes choosing your structure and preparing for that $800 franchise tax (Week 1), getting your EIN and researching local permit requirements (Week 2), filing all paperwork and applying for industry-specific licenses (Week 3), and setting up insurance plus employment law compliance (Week 4).
This timeline assumes you're prepared for California's complexity and have professional guidance—trying to navigate the state's requirements solo typically adds 2-4 weeks to the process.
Week 1: Foundation and Tax Planning
- Choose business structure (LLC recommended for most small businesses)
- Reserve your business name through California Secretary of State
- Calculate franchise tax timing and cash flow impact
- Research county-specific DBA requirements if needed
Week 2: Federal Registration and Local Research
- Apply for federal EIN through IRS (free, takes 24-48 hours online)
- Research city business license requirements for your location
- Identify industry-specific permits (health, professional, ABC, etc.)
- Open business bank account using EIN and formation documents
Week 3: State and Local Filings
- File Articles of Organization/Incorporation with California Secretary of State
- Submit city business license applications
- Apply for California seller's permit if selling goods
- File DBA and arrange newspaper publication if needed
Week 4: Insurance and Compliance Setup
- Get workers' compensation insurance quotes (required before hiring first employee)
- Purchase general liability and other necessary insurance
- Set up California employment law compliance systems
- Register with Employment Development Department if hiring employees immediately
Pro Tip: Start insurance shopping in Week 1, not Week 4. California's workers' compensation requirements are strict, and getting proper coverage can take 1-2 weeks from application to policy activation.
What's Your Bottom Line for California Business Success?
California demands more upfront investment, regulatory compliance, and ongoing attention than almost any other state—but it also offers market opportunities that can make those challenges worthwhile.
Your minimum realistic budget is $2,000-$5,000 for simple service businesses, $10K-$25K for retail operations, and $25K+ for restaurants, but you're entering markets where successful businesses routinely outperform entire regions in other states.
The entrepreneurs who succeed here treat California's complexity as a competitive moat that keeps out less committed competitors, while the state's consumer spending power, innovation ecosystem, and diverse markets create opportunities for premium pricing and rapid scaling that simply don't exist elsewhere.
Your Next Move: File your business structure this week and start the franchise tax clock—every month you wait is another month before you can start capturing California's outsized market opportunity.
