California: Opportunity Meets Regulation

California is the largest economy in the United States and the fifth largest in the world. Its massive consumer market, innovation ecosystem, and diverse workforce make it an incredible place to build a business. But California also has the most complex regulatory environment of any state, with extensive employment laws, aggressive tax enforcement, strict environmental regulations, and pioneering data privacy requirements.

This guide covers every major compliance area for California small businesses in 2026. Whether you are based in Los Angeles, San Francisco, San Diego, Sacramento, or anywhere in between, understanding these requirements is essential for operating legally and avoiding costly penalties. For a personalized checklist tailored to your specific California business, try our free compliance wizard.

Business Formation in California

Forming Your Entity

California recognizes all standard business structures. To form an LLC or corporation:

LLC: File Articles of Organization with the California Secretary of State. Filing fee is $70. Processing takes approximately 3-5 business days online.
Corporation: File Articles of Incorporation. Filing fee is $100.
Sole proprietorship: File a Fictitious Business Name Statement (DBA) with the county clerk in the county where your business is located. Publish in a local newspaper as required.

Statement of Information

California LLCs must file a Statement of Information within 90 days of formation and biennially thereafter ($20 fee). Corporations must file annually ($25 fee). This filing provides the state with current information about your business officers, directors, and registered agent.

Registered Agent

Every California LLC and corporation must maintain an agent for service of process with a California street address. You can serve as your own agent or use a professional registered agent service.

California Tax Obligations

Franchise Tax

California imposes an annual minimum franchise tax of $800 on LLCs, corporations, and LPs. This tax is due even if your business has no income. The franchise tax is due by the 15th day of the 4th month after your fiscal year begins (April 15 for calendar-year filers).

First-year exemption: California currently exempts the minimum franchise tax for the first taxable year of newly formed LLCs, corporations, and LPs. Verify the current status of this exemption, as it has been extended multiple times but may sunset.

LLC Fee

In addition to the minimum franchise tax, California LLCs with total income from California sources above $250,000 must pay an additional LLC fee:

$250,000 - $499,999: $900
$500,000 - $999,999: $2,500
$1,000,000 - $4,999,999: $6,000
$5,000,000+: $11,790

This fee is based on total income, not profit, making it particularly burdensome for high-revenue, low-margin businesses.

Corporate Tax

C-corporations pay an 8.84% corporate income tax on net income. S-corporations pay a 1.5% tax on net income (minimum $800). These rates are among the highest in the nation.

Sales and Use Tax

California's statewide base sales tax rate is 7.25%, but local add-ons bring the actual rate to between 7.25% and 10.75% depending on location. Register for a seller's permit through the California Department of Tax and Fee Administration (CDTFA) before making any taxable sales.

California taxes many services that other states exempt and has complex rules about marketplace facilitator obligations, drop shipping, and digital goods. Check our regulations database for current sales tax rules.

Payroll Taxes

California employers must withhold and remit several state payroll taxes:

State income tax withholding using the employee's DE-4 form
State Disability Insurance (SDI): Employee-funded; current rate is approximately 1.1% of wages up to a cap
Paid Family Leave (PFL): Funded through SDI contributions
Employment Training Tax (ETT): Employer-paid; 0.1% on the first $7,000 per employee
State Unemployment Insurance (SUI): Employer-paid; new employer rate is 3.4% on the first $7,000 per employee

Employment Law in California

California has the most employee-protective labor laws in the country. Non-compliance is expensive and aggressively enforced.

Minimum Wage

California's minimum wage for 2026 is adjusted annually based on the Consumer Price Index. As of recent years, the statewide minimum has been among the highest in the nation. Many California cities and counties have even higher local minimum wages:

San Francisco, Berkeley, Emeryville, West Hollywood: Among the highest in the state
Los Angeles, San Jose, Oakland: Higher than the statewide minimum

Always pay the highest applicable rate.

Overtime Rules

California overtime laws are stricter than federal rules:

Daily overtime: 1.5x regular rate for hours over 8 in a workday
Double time: 2x regular rate for hours over 12 in a workday
Seventh consecutive day: 1.5x for the first 8 hours; 2x after 8 hours
California's salary threshold for overtime exemption exceeds the federal threshold

For more on overtime compliance, see our DOL overtime rules guide.

Meal and Rest Breaks

California requires:

Meal breaks: A 30-minute unpaid meal break for shifts over 5 hours; a second meal break for shifts over 10 hours. Must be provided before the end of the 5th and 10th hours respectively.
Rest breaks: A paid 10-minute rest break for every 4 hours worked (or major fraction thereof)
Penalties: One hour of premium pay for each missed meal or rest break

This is one of the most litigated areas of California employment law. Document compliance meticulously.

Paid Sick Leave

California requires employers to provide at least 5 days (40 hours) of paid sick leave per year to all employees who work 30+ days in a year. Some localities require more. Sick leave accrues at a rate of at least one hour per 30 hours worked, or employers can frontload the full amount at the beginning of the year.

California Family Rights Act (CFRA)

Employers with 5 or more employees must provide up to 12 weeks of job-protected unpaid leave for:

Birth, adoption, or foster care placement
Serious health condition of the employee or a family member
Military exigency

This is broader than federal FMLA, which covers employers with 50+ employees.

Pay Transparency

California requires employers with 15+ employees to include salary ranges in all job postings. Employers must also provide the pay scale for a current employee's position upon request.

Worker Classification (AB 5)

California's AB 5 law codified the "ABC test" for determining whether a worker is an employee or independent contractor. Under this test, a worker is presumed to be an employee unless the hiring entity can demonstrate:

A: The worker is free from the control and direction of the hiring entity
B: The worker performs work outside the usual course of the hiring entity's business
C: The worker is customarily engaged in an independently established trade or business

Several professions have exemptions, but the default is strict employee classification. Misclassification penalties in California are severe.

CalOSHA

California operates its own occupational safety and health program (CalOSHA), which is at least as strict as federal OSHA and often more so. Unique California requirements include:

Injury and Illness Prevention Program (IIPP): Every California employer must have a written IIPP, regardless of size
Heat illness prevention: Required for outdoor workers
Wildfire smoke protection: Required for outdoor workers when air quality is hazardous
COVID-19 prevention: Ongoing requirements that may still be in effect

Data Privacy (CCPA/CPRA)

California's consumer privacy law applies to for-profit businesses that meet any one of these thresholds:

Annual gross revenue over $25 million
Buy, sell, or share personal information of 100,000+ consumers
Derive 50%+ of annual revenue from selling/sharing personal information

Key requirements:

Provide a "Do Not Sell or Share My Personal Information" link on your website
Honor consumer requests to access, delete, correct, and port their data
Conduct regular data protection assessments for high-risk processing
Implement reasonable security measures

Even businesses under these thresholds should maintain a privacy policy and follow data protection best practices. For more on data privacy, see our glossary of compliance terms.

Environmental Regulations

California has the strictest environmental regulations in the nation:

CEQA (California Environmental Quality Act): May require environmental review for business projects
Air quality permits: Required from local Air Quality Management Districts for businesses with emissions
Hazardous waste: Strict rules for generation, storage, transport, and disposal (regulated by DTSC)
Water quality: Stormwater permits may be required for construction, industrial, and commercial activities
Proposition 65: Requires businesses to warn consumers about exposure to chemicals known to cause cancer or reproductive harm. This applies to products, premises, and environmental releases.

Proposition 65 compliance is particularly important because it creates a private right of action—individuals (and their attorneys) can sue businesses for failing to provide required warnings.
