Requirement Category Specific Requirement Description
Business Structure & Registration Selecting a Business Structure Choosing the right business structure (sole proprietorship, partnership, LLC, corporation, etc.) impacts liability, taxation, and administrative requirements. Each structure has unique advantages and disadvantages.
Registering Your Business Name Registering your business name (DBA - Doing Business As - for sole proprietorships and partnerships or filing Articles of Incorporation/Organization for corporations/LLCs) with the California Secretary of State. This ensures legal recognition and allows you to operate under that name.
Articles of Incorporation/Organization Filing these documents with the California Secretary of State is mandatory for corporations and LLCs. These documents outline the basic structure, purpose, and management of the entity. They include information such as the business name, registered agent, and initial directors/members.
Obtaining an Employer Identification Number (EIN) If you plan to hire employees or operate as a corporation or partnership, you'll need an EIN from the IRS. This is a unique tax identification number for your business. Sole proprietorships without employees may use their Social Security Number, but an EIN is generally recommended for business purposes.
Licenses & Permits Business Licenses Obtaining the necessary business licenses from the city and/or county where your business operates. Requirements vary depending on the type of business and location. These licenses ensure that your business complies with local regulations and zoning laws.
Professional Licenses Specific licenses or certifications required for certain professions (e.g., doctors, lawyers, contractors, cosmetologists). These licenses ensure that individuals providing professional services meet certain standards of competence and ethical conduct. The specific licensing board or agency will vary depending on the profession.
Seller's Permit (Resale Permit) Required if you plan to sell tangible personal property in California. This allows you to collect sales tax from customers and remit it to the California Department of Tax and Fee Administration (CDTFA). Without a seller's permit, you cannot legally collect sales tax.
Environmental Permits May be required for businesses that could potentially impact the environment (e.g., manufacturers, restaurants, auto repair shops). These permits ensure compliance with environmental regulations and protect air and water quality. The specific permits required will depend on the nature of your business and its potential environmental impact.

Detailed Explanations:

Business Structure & Registration

Selecting a Business Structure: The foundation of your business lies in its structure. The most common choices include:

  • Sole Proprietorship: Simple to set up, with minimal paperwork, but you are personally liable for all business debts.
  • Partnership: Two or more individuals agree to share in the profits or losses of a business. Like sole proprietorships, partners typically face personal liability.
  • Limited Liability Company (LLC): Offers liability protection, separating your personal assets from business debts. It also provides flexibility in taxation, allowing you to choose to be taxed as a sole proprietorship, partnership, or corporation.
  • Corporation (C-Corp or S-Corp): A more complex structure, offering the strongest liability protection. C-Corps are subject to double taxation (corporate level and shareholder level), while S-Corps allow profits and losses to be passed through to the owners' individual tax returns.

Registering Your Business Name: Your business name is your identity. If you are operating under a name different from your own (for sole proprietorships and partnerships), you must file a "Doing Business As" (DBA) statement, also known as a fictitious business name statement, with the county clerk's office in the county where your business is located. Corporations and LLCs register their names when they file their Articles of Incorporation or Organization with the California Secretary of State. This process ensures that no other business is using the same name in your jurisdiction.

Articles of Incorporation/Organization: These are the foundational documents for corporations and LLCs. The Articles of Incorporation (for corporations) and Articles of Organization (for LLCs) are filed with the California Secretary of State. They define the business's purpose, registered agent (who receives legal notices), and the initial management structure. Accurate and complete filing is crucial for establishing your business as a legal entity.

Obtaining an Employer Identification Number (EIN): An EIN is essentially a Social Security number for your business. You need an EIN from the IRS if you plan to hire employees, operate as a corporation or partnership, or if your business is required to file certain types of tax returns. Even if not strictly required, obtaining an EIN can help protect your personal Social Security number and simplify business transactions.

Licenses & Permits

Business Licenses: Almost every business in California needs a general business license, often called a business tax certificate or permit, from the city and/or county where it operates. The specific requirements vary based on the type of business and its location. Contact your local city hall or county clerk's office to determine the necessary licenses and permits. Failing to obtain these licenses can result in fines and penalties.

Professional Licenses: Many professions in California require specific licenses or certifications to operate legally. This includes professions like doctors, lawyers, accountants, contractors, real estate agents, and cosmetologists. These licenses are typically issued by state boards or agencies and demonstrate that the individual has met certain educational and experience requirements and has passed an examination. Contact the relevant licensing board for your profession to determine the specific requirements.

Seller's Permit (Resale Permit): If your business sells tangible personal property in California, you are required to obtain a seller's permit from the California Department of Tax and Fee Administration (CDTFA). This permit allows you to collect sales tax from your customers and remit it to the state. You must prominently display your seller's permit at your place of business.

Environmental Permits: Businesses that may impact the environment, such as manufacturers, restaurants, auto repair shops, and dry cleaners, may need to obtain environmental permits from various state and local agencies. These permits regulate activities that could potentially pollute air, water, or soil. Contact your local environmental health department or the California Environmental Protection Agency (CalEPA) to determine if your business requires any environmental permits.

Taxation

State Income Tax: All businesses operating in California are subject to state income tax. The specific tax rate and filing requirements depend on the business structure. Corporations are subject to the corporate income tax, while sole proprietorships, partnerships, and LLCs (depending on their election) are considered pass-through entities, meaning that the business income is passed through to the owners' individual tax returns. It's essential to understand your tax obligations and file your returns accurately and on time to avoid penalties.

Payroll Tax: If you have employees, you are responsible for withholding and remitting payroll taxes to both the federal and state governments. This includes federal income tax, Social Security tax, Medicare tax, and California state income tax, unemployment insurance, and employment training tax. You will need to register with the California Employment Development Department (EDD) to handle payroll taxes.

Sales Tax: As mentioned earlier, if you sell tangible personal property, you must collect sales tax from your customers and remit it to the CDTFA. Sales tax rates vary depending on the location of the sale. It's crucial to accurately calculate and collect sales tax and file your returns on time to avoid penalties.

Property Tax: If your business owns real property or certain types of personal property, you may be subject to property tax. Property taxes are assessed and collected by the county in which the property is located.

Labor Laws

Minimum Wage: As of 2025, California's minimum wage is expected to continue increasing. Ensure you are paying your employees at least the current minimum wage. There may be different minimum wage requirements for certain cities and counties, so it's essential to check local ordinances.

Overtime Pay: California has strict overtime pay laws. Generally, employees are entitled to overtime pay (1.5 times their regular rate) for any hours worked over 8 in a workday or 40 in a workweek. Certain industries and occupations may have different overtime rules.

Meal and Rest Breaks: California law requires employers to provide employees with meal breaks (typically 30 minutes) and rest breaks (typically 10 minutes) during the workday. The specific requirements depend on the length of the workday.

Paid Sick Leave: California requires employers to provide paid sick leave to their employees. Employees accrue paid sick leave at a rate of one hour for every 30 hours worked.

Workers' Compensation Insurance: If you have employees, you are required to carry workers' compensation insurance to cover medical expenses and lost wages for employees who are injured on the job.

Data Privacy Laws

California Consumer Privacy Act (CCPA): The CCPA grants California consumers significant rights regarding their personal information. Businesses that collect personal information from California residents must comply with the CCPA, which includes providing consumers with notice of their data collection practices, allowing them to access their personal information, and giving them the right to opt out of the sale of their personal information.

California Privacy Rights Act (CPRA): The CPRA expands on the CCPA and creates new privacy rights for California consumers, including the right to correct inaccurate personal information and the right to limit the use of sensitive personal information.

Intellectual Property Protection

Trademarks: Protect your brand name and logo by registering a trademark with the California Secretary of State or the U.S. Patent and Trademark Office (USPTO).

Copyrights: Protect your original works of authorship, such as writings, music, and artwork, by registering a copyright with the U.S. Copyright Office.

Trade Secrets: Protect confidential business information that gives you a competitive edge, such as formulas, processes, and customer lists, by taking steps to maintain its secrecy.

Contracts

Written Agreements: It's essential to have written contracts with your customers, suppliers, and employees to clearly define the terms of your agreements and protect your business interests.

Legal Review: Before signing any important contracts, have them reviewed by an attorney to ensure they are legally sound and protect your rights.
