There is no single California business license. To legally open a business in California, you assemble a stack of filings across three levels of government: state registration if you’re forming an entity, any industry-specific state permits or professional licenses, and a local business tax certificate from the city (and sometimes county) where you operate. The exact combination depends on what you sell and where you’re located.
Figure Out Which Licenses Apply to You
Before you file anything, map out what your specific business actually needs. A restaurant in Sacramento faces a very different list than a freelance graphic designer in San Diego, and assuming one application covers everything is the most common early mistake.

You enter your city and business type, and it returns the permits you need along with the issuing agency, application links, and fees.1California Governor’s Office of Business and Economic Development. Guide to Permits, Licensing and Regulations Run your business through it first so you don’t discover a missing permit after you’ve opened your doors.
Register Your Entity With the Secretary of State
If you’re forming an LLC, corporation, or limited partnership, you must register with the California Secretary of State before any operating licenses. Sole proprietors and general partnerships skip this step unless they want formal entity protection.
An LLC files Articles of Organization for $70.2California Secretary of State. Limited Liability Companies (LLC) – California Corporations file Articles of Incorporation. Both can be submitted through the Secretary of State’s bizfile portal.
Then plan for the ongoing cost. Once you form an LLC or corporation, the Franchise Tax Board charges an $800 annual minimum franchise tax, and it’s due even in years the business earns nothing.3California Franchise Tax Board. Limited Liability Company That obligation continues until you formally cancel the entity. Corporations formed on or after January 1, 2020 are exempt from the minimum franchise tax in their first taxable year.4California Franchise Tax Board. Corporations Budget for the $800 from day one; it catches many first-time owners off guard.
Get a Federal EIN Early
An Employer Identification Number is a federal tax ID from the IRS, not a California license, but you’ll want it in hand before you fill out most state and local applications. The IRS requires an EIN if you have employees or operate as a corporation, partnership, or LLC, or need to file employment or excise taxes.5Internal Revenue Service. Employer Identification Number Even when it isn’t legally required, most banks won’t open a business account without one.
You apply online through the IRS at no cost using Form SS-4, and the number is typically issued immediately. The form asks for entity type, legal name, business address, and the Social Security Number or ITIN of the responsible party.6Internal Revenue Service.

Get Your Local Business Tax Certificate
This is the closest thing to a “general business license” in California. Most cities and many counties require one, and it grants you permission to operate inside that jurisdiction.
Apply through the business license or finance department of the city where your business is physically located. You’ll usually provide your business name, address, activity type, owner details, and EIN. Some jurisdictions require zoning verification or agency clearance first. Food businesses, for example, often need health department sign-off before the city will issue the tax certificate.
Fees vary. Some cities charge a flat annual amount; others base it on gross receipts or employee count. Home-based businesses generally still need the certificate, and some cities require a separate home occupation permit confirming that your activity is compatible with residential zoning. If you add a new physical location in another city, you’ll need a separate tax certificate there too.
Get a Seller’s Permit If You Sell Taxable Goods
Any business that sells or leases tangible personal property in California needs a seller’s permit from the California Department of Tax and Fee Administration.7California Department of Tax and Fee Administration. Frequently Asked Questions – Seller’s Permit That covers retailers, wholesalers, and manufacturers. If the product would be subject to sales tax at retail, you need the permit even when you’re only selling wholesale.
The permit itself is free. You register online with the CDTFA, providing your business name and each location where you conduct sales.8California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6066 You need a separate permit for each place of business where you negotiate transactions with customers.9California Department of Tax and Fee Administration. California Code of Regulations Title 18 Division 2 Chapter 4 Regulation 1699 – Permits
Service-only businesses that never sell physical goods generally don’t need a seller’s permit. Consultants, therapists, and software developers who never deliver tangible property can usually skip this one.
Check Whether Your Profession Needs a State License
Some occupations can’t legally operate in California without a state-issued license, no matter what city they’re in. Contractors, cosmetologists, real estate agents, accountants, and doctors are common examples. The Department of Consumer Affairs oversees dozens of licensing boards covering these regulated professions.10Department of Consumer Affairs. Department of Consumer Affairs Licensees
Requirements vary by field but commonly include a mix of education, supervised experience, and passing an exam. These applications also run on longer timelines than general business permits, so plan for weeks to months rather than days. Check your specific licensing board for current fees, forms, and eligibility rules.
File a Fictitious Business Name Statement If You Use a DBA
If you operate under any name other than your own legal name (for individuals) or the exact name on file with the Secretary of State (for LLCs and corporations), California requires a fictitious business name statement, often called a DBA. These are filed at the county level; there is no statewide DBA registry.
After filing with your county clerk or recorder, you must publish the statement in a newspaper of general circulation in that county once a week for four consecutive weeks, and you have 30 days from filing to start publication. The statement is valid for five years, then must be refiled. County filing fees typically run about $26 to $31. Filing a statement you know to be false is a misdemeanor punishable by a fine of up to $1,000.
Carry Workers’ Compensation Insurance If You Hire
If you hire even one employee, California law requires workers’ compensation insurance. There is no minimum employee threshold and no waiting period; the obligation starts with your first hire.11California Department of Industrial Relations. DWC FAQs for Employers Some licensing agencies, especially the Contractors State License Board, ask for proof of coverage as part of the license application or renewal.
Sole proprietors with no employees are generally exempt, though certain high-risk industries may still require coverage. If you plan to use independent contractors, be careful: California’s worker classification rules under AB 5 mean many workers who look like contractors may legally be employees, which triggers the insurance requirement.
What Happens If You Skip a Required License
Operating without a required license isn’t just a paperwork issue. Under California Business and Professions Code Section 16240, practicing any business, trade, or profession that requires a state license without holding a current and valid one is a misdemeanor.12California Legislative Information. California Business and Professions Code BPC 16240 For contractors, the penalties escalate quickly: a first conviction can bring a fine up to $5,000 and up to six months in county jail, and subsequent convictions carry steeper fines and mandatory minimum jail time.
The practical consequences add up too. You may be unable to enforce contracts in court, your business insurance can deny claims, and you’ll owe back taxes and penalties from every agency you missed. Local jurisdictions can also issue cease-and-desist orders that shut you down until you’re properly licensed.
Renewals and Changes
Most local business tax certificates renew annually, on a schedule the city sets. In Los Angeles, business taxes are due January 1 and become delinquent after the last day of February.13Los Angeles Office of Finance. Business Tax Renewal Instructions Your city will typically mail a renewal notice, but the responsibility to renew on time is yours whether or not one shows up.
Professional licenses through state boards usually renew on a two-year cycle and often require continuing education. Your seller’s permit stays valid as long as you’re in business, but you must notify the CDTFA if you move, change ownership, or close. Fictitious business name statements expire after five years and must be refiled.
Any time your business changes address, ownership, activity, or adds a location, check whether existing permits need updating. Renewal forms are almost always simpler than the original application, but missing a deadline can trigger penalties that cost more than the license itself.
