Yes — if you’re operating a business in California, you almost certainly need a license, but not a single statewide one. California doesn’t issue one general business license. Instead, nearly every business needs a local business operating license (often called a business tax certificate) from its city or county, and depending on what you do, you may also need a state professional license, a seller’s permit, or industry-specific permits from state or federal agencies.
The Local Business License Almost Every Business Needs
This is the license most people are asking about. Most California cities and many counties require any enterprise conducting business within their boundaries to obtain a general business operating license, frequently called a business tax certificate. The requirement applies regardless of your business structure. Home-based businesses, freelancers, and independent contractors are not exempt.
The purpose is straightforward: registering your business with the local government for tax purposes. Fees vary widely by jurisdiction and may be a flat rate or calculated based on projected revenue or employee count. If your business operates in more than one city or county, you need a separate license from each one.
To find the exact requirements and fees for your location, check the official website of your city or county finance department. Applications are usually available online, by mail, or at a public counter, and many cities now offer a fully digital process including online payment.
When You Also Need a State Professional License
Certain professions require a state-issued license before you can legally practice in California. The California Department of Consumer Affairs oversees dozens of regulatory boards covering fields like automotive repair, cosmetology, contracting, and medicine.1Department of Consumer Affairs. Boards/Bureaus – Department of Consumer Affairs Each board sets its own educational prerequisites, examinations, and fees.
This licensing is about the person, not the business. A licensed cosmetologist still needs a local business license to open a salon. A general contractor still needs a Contractors State License Board license on top of whatever city permits the job requires. These layers stack; they don’t replace each other.
When You Also Need a Seller’s Permit
Any business that sells or leases tangible goods in California needs a seller’s permit from the California Department of Tax and Fee Administration. That includes retailers, wholesalers, and manufacturers. The permit authorizes you to collect sales tax from customers and is a separate requirement from your local business license.2California Department of Tax and Fee Administration. Obtaining a Sellers Permit
There is no fee for the permit itself, but the CDTFA may require a security deposit to cover potential unpaid taxes if you later close the business. The deposit amount is determined when you apply.3California Department of Tax and Fee Administration.

Industry-Specific and Federal Permits
Many industries carry their own permit requirements on top of everything above. Food businesses need a health permit from their county environmental health department before serving, preparing, or packaging food. Businesses handling hazardous materials, operating in construction, or selling alcohol each have their own permitting agencies. Federally regulated industries — agriculture across state lines, firearms, commercial fishing, broadcasting, aviation, alcohol manufacturing and wholesale, and a handful of others — need federal permits from the relevant agency in addition to state and local licenses.5U.S. Small Business Administration.

What to Handle Before You Apply: Entity Registration and DBA
Before you apply for a local business license, you may need to formally register your business entity with the California Secretary of State. Many local agencies want proof of entity registration before they’ll issue a license.
Whether registration is required depends on your structure:
- Corporations file Articles of Incorporation.
- LLCs file Articles of Organization through the Secretary of State’s bizfileOnline portal.
- Limited partnerships file a Certificate of Limited Partnership.
- Limited liability partnerships file an Application to Register.
- Sole proprietors file nothing with the Secretary of State.
- General partnerships can register at the state level, but it’s optional.7California Secretary of State. Starting a Business – Entity Types
Separately, if you operate under any name other than your own legal name or your registered entity name, California requires you to file a Fictitious Business Name Statement — commonly called a DBA — with the county clerk in the county where your principal place of business sits. This applies to any for-profit business using a trade name; nonprofit corporations are exempt. Most counties allow online filing.8LA County Registrar-Recorder/County Clerk.

What Changes the Moment You Hire
Two obligations kick in when you take on employees, and both catch new owners off guard.
First, you must register as an employer with California’s Employment Development Department within 15 days of paying more than $100 in wages in a calendar quarter. Household employers register once they pay more than $750 in cash wages per quarter. Registration is handled online through the EDD’s e-Services for Business portal.9Employment Development Department. Am I Required to Register as an Employer
Second, California requires every employer with even one employee to carry workers’ compensation insurance. There are no exceptions based on business size or industry. You satisfy the requirement by purchasing a policy from an authorized insurer, or, if you’re a larger employer, by obtaining a certificate of consent to self-insure from the Director of Industrial Relations.10California Legislative Information. California Labor Code Section 3700
What Happens if You Skip a Required License
Penalties range from monetary fines to criminal charges, and they depend on which license you’re missing.
Local License Violations
Cities and counties can impose penalties for operating without a local business license, including late fees and back taxes for the entire unlicensed period. Some municipalities calculate fines as a percentage of your gross revenue during that time. A city or county can also issue a cease-and-desist order, shutting your business down until you’re properly licensed.
Unlicensed Contracting
Contracting without a state license is one of the more aggressively prosecuted licensing violations in California. It’s a misdemeanor with escalating penalties:
- First offense: a fine of up to $5,000 or up to six months in county jail, or both.
- Second offense: a fine of $5,000 or 20 percent of the contract price (whichever is greater), plus at least 90 days in county jail. A judge can impose a lesser sentence only by stating the reasons on the record.
- Third or subsequent offense: a fine between $5,000 and $10,000 (or 20 percent of the contract price if higher), plus 90 days to one year in county jail.11California Legislative Information. California Code, Business and Professions Code BPC Section 7028
On top of criminal penalties, the Contractors State License Board can issue a separate administrative citation with civil penalties ranging from $200 to $15,000 per violation.12California Legislative Information. California Business and Professions Code Section 7028.7
Workers’ Compensation Violations
Operating without workers’ compensation insurance is a misdemeanor carrying a fine of at least $10,000 or up to one year in county jail, or both. The state can also issue a stop order that shuts your business down until you get coverage, and assess a penalty of twice what your premiums would have been during the uninsured period, or $1,500 per employee, whichever is greater. If an employee is injured while you’re uninsured, the Workers’ Compensation Appeals Board can add penalties of $10,000 per employee on your payroll at the time of injury.13Department of Industrial Relations.

California layers its licensing requirements across local, state, and federal levels, and missing any one of them creates real exposure. Running your business through CalGold before you open is the most efficient way to see every license and permit that applies to your specific situation.
