Yes. In almost every case, an LLC needs a business license in California—forming the LLC with the Secretary of State creates the entity, but it doesn’t authorize you to operate. Most LLCs need at least a local business tax certificate from the city or county where they work, and many also need a state seller’s permit, a professional or occupational license, or a federal permit depending on what they sell and do.
The Local Business Tax Certificate
When people say “business license,” they usually mean the registration required by their city or county. Nearly every California city and county requires businesses to obtain what is typically called a business tax certificate before opening. San Diego calls it a Business Tax Certificate rather than a business license, but the obligation is the same: register with the city and pay the tax.1City of San Diego.

This applies whether your LLC runs a retail storefront, an office-based consultancy, or a home-based online business. Fees range from small flat amounts to a percentage of gross receipts depending on the city. San Diego’s base business tax is $34 plus a $4 state-mandated fee; Los Angeles calculates the tax based on your revenue.1City of San Diego. Apply for a Business Tax Certificate Certificates renew annually, and the renewal is due whether or not you turned a profit.
To apply, you’ll typically need your Federal Employer Identification Number, a description of your activities, your business address, and projected revenue. Home-based businesses often need a separate home occupation permit or zoning clearance from the same city.
Seller’s Permit for Taxable Goods
If your LLC sells or leases tangible goods subject to sales tax, you also need a seller’s permit from the California Department of Tax and Fee Administration. The requirement covers both wholesale and retail sellers.3California Department of Tax and Fee Administration. Obtaining a Seller’s Permit Service-only businesses that never sell physical goods generally don’t need one.
There’s no fee to obtain the permit, though CDTFA may require a security deposit to cover potential unpaid taxes if the business later closes.3California Department of Tax and Fee Administration. Obtaining a Seller’s Permit You apply online through CDTFA. This is separate from LLC formation and from any local certificate you also need.
Operating without a seller’s permit when one is required is a misdemeanor. A court can impose a fine of up to $5,000, a jail sentence of up to one year, or both, and CDTFA can assess back taxes, interest, and additional penalties on top of that.4California Department of Tax and Fee Administration.

Industry-Specific State Licenses
Many California LLCs can’t legally operate with just a local certificate and a seller’s permit. If you work in a regulated field, you also need a professional or occupational license from the state board that oversees it. Each board sets its own experience requirements, exams, fees, and renewal schedules.
A few common examples:
- Construction. The Contractors State License Board requires a license for any project valued at $500 or more in combined labor and materials. Applicants must show at least four years of journey-level experience and pass trade and law exams.
- Auto repair. The Bureau of Automotive Repair requires an Automotive Repair Dealer license to diagnose, service, or repair vehicles for compensation. The application fee is $200, with a $200 annual renewal.5Bureau of Automotive Repair. Apply for a License
- Barbering and cosmetology. The Board of Barbering and Cosmetology licenses both individual practitioners and the establishments where they work.6California Board of Barbering and Cosmetology. California Board of Barbering and Cosmetology
These are three of dozens of regulated professions. Accountants, real estate agents, private investigators, pest control operators, and many healthcare providers all face separate licensing through their respective state boards, most of them under the California Department of Consumer Affairs.7California Secretary of State.

Federal Permits for Certain Industries
A smaller number of California LLCs also need federal permits. Businesses that manufacture, deal, or import firearms need a Federal Firearms License from the ATF, with initial application fees ranging from $30 to $3,000 depending on the license type and three-year renewals.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Firearms Licenses Other examples include FCC licenses for broadcasting, USDA permits for handling animals or meat products, and EPA permits for operations that generate hazardous waste.9US Environmental Protection Agency.

The $800 Franchise Tax Is Not a License
New owners often confuse this with a licensing fee. It isn’t, but it’s still mandatory. Every LLC organized or doing business in California must pay an $800 annual franchise tax to the Franchise Tax Board, whether or not the business earns any income.10Franchise Tax Board. Limited Liability Company California briefly waived this for new LLCs in their first year from 2021 through 2023, but the Legislature did not renew that exemption. LLCs formed in 2024 and later owe the full $800 from their first taxable year.
LLCs with higher revenue pay an additional fee on top of the $800 base, tiered by total California income:10Franchise Tax Board. Limited Liability Company
- $250,000 to $499,999: $900 additional fee
- $500,000 to $999,999: $2,500 additional fee
- $1,000,000 to $4,999,999: $6,000 additional fee
- $5,000,000 or more: $11,790 additional fee
Failing to pay can lead the Franchise Tax Board to suspend your LLC’s powers, rights, and privileges, which effectively bars you from legally conducting business in the state.
How to Figure Out What Your LLC Actually Needs
California’s CalGold tool is the best starting point for building a checklist. The state created it specifically to help businesses navigate overlapping local, state, and federal requirements.11CalGold. CalGold – Permit Assistance Tool You enter your business address, select your industry, and describe your activities. CalGold generates a report listing the permits, licenses, and registrations that apply, with contact information for each issuing agency.12CA.gov. Get Permit Assistance
CalGold is thorough but not perfect. It can miss niche federal requirements or city-specific zoning rules. After running it, confirm directly with your city’s business licensing office and any state board that regulates your profession.
Penalties for Operating Without the Right License
Consequences vary by which license you’re missing, but none of them are minor. Local jurisdictions can impose fines, collect back taxes with interest, and in some cases file misdemeanor charges. Steeper penalties come from the state agencies overseeing regulated industries.
Unlicensed contracting is the heaviest example. A first conviction is a misdemeanor carrying up to six months in county jail, a fine of up to $5,000, or both. The CSLB can also impose an administrative fine between $200 and $15,000.13California Legislative Information. California Assembly Bill 370 – Unlicensed Contractors14Contractors State License Board. Consequences of Contracting Without a License Repeat convictions carry mandatory jail minimums and higher fines tied to the contract price.
The most punishing consequence often isn’t criminal. Under California law, a contractor who performs work without a license cannot bring a legal action to collect payment for that work. A court will refuse to enforce the contract, meaning the client has no legal obligation to pay for the job.15California Legislative Information. California Code BPC Division 3 Chapter 9 Article 2 Section 7031 That alone makes verifying every license before you take on work worth the few hours it takes.
