Overview: What "LA Business Registration" Actually Means
LA business registration typically involves three layers: the city of Los Angeles, Los Angeles County, and federal or state agencies. Each has distinct requirements, and most owners need to register early with the correct local, state, and federal agencies before starting operations, since confusing them is one of the most common (and costly) mistakes new business owners make. Registering a business in Los Angeles requires a business tax registration certificate, but that's just one piece of the puzzle.
Note: "LA" in this guide refers to Los Angeles, California-not Louisiana. Louisiana offers five main business structures (LLC, corporation, partnership, sole proprietorship, and nonprofit) and uses the geauxBIZ portal to register new businesses. If you're looking for the louisiana department of revenue, the louisiana secretary of state, or the louisiana workforce commission, those are separate systems entirely. This guide covers Los Angeles.
- City of Los Angeles: Requires a business tax registration certificate (BTRC) for most businesses operating within the city limits
- Los Angeles County: Requires a fictitious business name statement if using a trade name, plus a la county business license for businesses in unincorporated areas
- State of California: Entity formation (LLC, corporation) through the california secretary of state; seller's permits; payroll tax accounts
- Federal: Employer identification number (EIN) from the IRS; federal tax obligations
Depending on your structure, location, and tax obligations, you may need to register your business with more than one authority.
Step 1: Choose Your Business Structure Before You Register
California law governs the legal structures available for businesses in Los Angeles. Your business structure determines your liability exposure, tax treatment, and which registrations you'll need. Common business structures in California include sole proprietorship, partnership, LLC, and corporation-you must choose before filing anything.
A limited liability company provides liability protection for its owners, while corporations provide the strongest liability protection but involve more complex regulations. Sole proprietorships are owned by a single individual and carry unlimited personal liability. Partnerships require two or more individuals or entities to own the business. A limited liability partnership is typically limited to licensed professionals in California, such as attorneys or accountants. Business structure affects tax filing requirements, so consult a CPA or attorney before deciding-government offices like the office of finance and the secretary of state do not provide legal advice.
Consider how requirements differ based on your business type:
- Sole proprietor (e.g., 2025 freelance designer): May only need a fictitious business name, BTRC, and possibly a small business exemption. Uses personal social security number unless hiring employees.
- LLC (e.g., 2025 food truck): Needs state formation, EIN, seller's permit, city BTRC, health permits, and possibly county permits. A limited liability company shields personal assets.
- Corporation: Most formal structure; separate legal entity owned by shareholders; subject to corporate taxes and stricter compliance.
- General partnership: Two or more owners sharing liability; state filing required for limited partnership or LLP variants.
- Nonprofit: Special formation, exempt status applications, and ongoing compliance.
-
Step 2: Lock In Your Business Name (Legal Name & Fictitious Business Name)
Your legal business name is the name on your state formation documents (Articles of Organization for an LLC, Articles of Incorporation for a corporation). A fictitious business name (DBA) is any name you use publicly that differs from that legal name. A fictitious business name statement must be filed if operating under a name differing from the legal name.
- Search the California Secretary of State website for entity name availability (corporations, LLCs)
- Search LA County's FBN database for trade name conflicts
- A sole proprietor using "Sunset Creative Studio" instead of their own last name must file a fictitious business name
- Finalize your business name before applying for a BTRC, opening bank accounts, or signing contracts-mismatched names create legal headaches
- Reserve the name at the state level if forming an entity; file the FBN with the county if using a DBA
Register Any Fictitious Business Names in Los Angeles County
Anyone doing business in los angeles county under a fictitious name must file a Fictitious Business Name Statement with the LA County Registrar-Recorder/County Clerk. The current base filing fee is $26 for the first business name and one registrant, with $5 for each additional name or owner.
- Search the county's FBN database for conflicts
- Complete the FBN Statement form with: owner's legal name, business name, physical business address in LA County (no P.O. boxes), business start date, and business structure
- Submit in person (Norwalk, Van Nuys, Lancaster offices) or by mail with a notarized Affidavit of Identity
- Pay the filing fee
- Obtain certified copies for your records and bank account applications
Meet LA County's Publication Requirement for Fictitious Business Names
After filing the FBN, you must publish the statement once a week for four consecutive weeks in a legally adjudicated los angeles county newspaper.
- Publication must begin within 30 days of filing-missing this window means re-filing and repaying fees
- Cost ranges from $45–$100 for community newspapers to several hundred dollars for major papers
- Many newspapers handle filing the Proof of Publication back to the Registrar-Recorder/County Clerk, but the responsibility remains yours
- Your fictitious business name registration is not complete until proof of publication is on file-without it, you may be unable to open bank accounts or enforce contracts under the trade name
Determine Whether You Need a City of Los Angeles or LA County Business License
"Los Angeles" can mean the City of Los Angeles, one of 88 cities in the county, or unincorporated LA County territory. Your business location determines which license you need.
Businesses physically located within the city limits (Hollywood, Downtown LA, Echo Park, Silver Lake) need a City BTRC. Businesses in unincorporated areas (Marina del Rey, East Los Angeles, Valinda) or contract cities like Malibu, Santa Clarita, or Westlake Village need a county business license instead.
- Use the LA city limits map or LA County jurisdictional tools to confirm your licensing authority
- Some businesses need both: a food facility in city limits needs a City BTRC plus LA County Public Health permits
- A small retail shop in unincorporated East Los Angeles needs a county license; the same shop in Hollywood needs a City BTRC

Get a Business Tax Registration Certificate (City of Los Angeles "Business License")
A business tax registration certificate is required to operate in LA. The BTRC is issued by the Los Angeles Office of Finance under LAMC Section 21 and applies to virtually all business activities within the city-storefronts, home-based operations, freelancers, and online sellers.
- Registration can be completed online or in person at LA office of finance locations
- A temporary certificate is issued immediately after online registration; the permanent certificate arrives by mail in about four weeks
- The business tax registration certificate must be renewed annually in Los Angeles, with city business tax calculated on business gross receipts from the prior calendar year
- Small businesses with annual gross receipts under $100,000 may qualify for exemptions but must still register
- Display your BTRC at your business location and update your business information whenever your address, structure, or ownership changes
How to Apply for a BTRC: Information and Documents You'll Need
The office of finance requires the following to process your business license application:
- Social security number (for individuals) or federal employer identification number (for entities)
- Legal business name and fictitious business name (if applicable)
- NAICS code with a description of your business activities
- Business start date in Los Angeles
- Physical business address and mailing address
- Business contact information (phone, email)
Regulated business activities trigger additional review-expect referrals for permits from Police, Fire, or Public Health if applicable. Walk through the online application: create an account → enter owner and business information → select tax classification → submit → print your temporary certificate. Some categories owe a minimum tax at registration, while others are billed at renewal based on gross receipts.
Register with the California Secretary of State (If Required by Your Structure)
Businesses must register with the california secretary of state for certain entity types. If you're forming a corporation, LLC, limited partnership, or limited liability partnership, state registration is required before or alongside local registrations.
- Corporations: Articles of Incorporation (Form ARTS-GS)
- LLCs: Articles of Organization (Form LLC-1) - $70 online filing fee; biennial Statement of Information ($20)
- Limited Partnership: Certificate of Limited Partnership (Form LP-1)
- LLP: Registration forms specific to the profession
Ongoing state obligations include biennial Statements of Information and the $800 annual minimum franchise tax for most entities.
Get Your Federal Tax Identification Number (Employer Identification Number)
Most businesses need a federal tax identification number, generally called an employer identification number (EIN) or federal employer identification number (FEIN). You need a federal employer identification number to register for most LA city and state filings.
- A sole proprietor with no employees can use a social security number, but an EIN is required when hiring employees, forming an LLC or corporation, or opening most business bank accounts
- Apply for free through the IRS online portal (same-day assignment), by fax, or by mail
- International applicants without an SSN may need an Individual Taxpayer Identification Number (ITIN)
- LA registration forms (BTRC, state filings) will ask for your EIN or federal employment identification number-obtain it early
Register with the California Department of Tax and Fee Administration & Employment Development Department
Beyond city and county licensing, most businesses must register for state-level tax accounts based on their business activities.
- Seller's Permit (CDTFA): Sales tax registration is required before making taxable sales. If you sell tangible personal property, obtain a permit from the California Department of Tax and Fee Administration before collecting sales tax. There's no fee for the permit itself; you'll receive a sales tax number for reporting. Most businesses need only one active withholding tax account for state purposes. You should also register with the louisiana department of revenue for tax accounts if you conduct business in Louisiana.
- Payroll Accounts (EDD): Employers with employees working in Los Angeles must register with the California Employment Development Department for payroll tax, unemployment insurance, and disability insurance
- Timing: Apply for CDTFA and EDD accounts shortly before your first taxable sale or first hire
LA County Business License Requirements Outside the City of Los Angeles
Businesses in unincorporated areas of la county or contract cities like Malibu, santa clarita, or westlake village need a county business license from the LA County Treasurer and Tax Collector. The license type and fee depend on your business activities-over 110 classifications exist.
- Determine the correct license classification for your business type
- Complete the county business license application and pay the non-refundable fee
- Obtain any required inspections (Health, Fire, Sheriff)
- Display the county business license at your premises
For example, a small retail shop in unincorporated East Los Angeles needs a county license, while the same shop in Hollywood (within city limits) needs a City BTRC instead.
Industry-Specific Permits and Approvals in Los Angeles
Specific industries may require additional permits beyond the main business registration certificate. Zoning regulations determine if a business can operate in a chosen location, and home-based businesses must comply with home occupation rules even without a formal permit.
- Police alarm permit: Required for businesses with alarm systems; initial and annual renewal fees apply
- Tobacco retailers permit: Required to sell tobacco products within city or county jurisdiction; separate from BTRC
- Fire permits: Needed for certain occupancies, hazardous materials storage, or special events
- LA County Public Health permits: Required for restaurants, mobile food vendors, and food facilities
- Zoning approval: Confirms your business location is authorized for your intended services
Costs, Timelines, and Common Mistakes in LA Business Registration
Most businesses pay an annual fee of $50–$150 for the business license, but total registration costs add up:
- State LLC formation: $70; biennial Statement of Information: $20
- FBN filing: $26 plus $45–$100 for publication
- BTRC: varies by gross receipts classification
- EIN: free, same-day online
- State entity approval: days to weeks; permanent BTRC: ~4 weeks; FBN publication: 4+ weeks
Common mistakes that cost real money:
- Registering with the wrong jurisdiction (city vs county)
- Missing the 30-day FBN publication window (requires re-filing)
- Failure to obtain a business license can lead to penalties and legal action-late BTRC renewals trigger 10% monthly penalties up to 40%
- Not updating business information after moving or changing structure
A freelance contractor who skipped BTRC registration because gross receipts were under threshold was later audited and assessed back-taxes plus penalties for multiple years.
Keeping Your LA Business Compliant After Registration
LA business registration is not a one-time task. Build a compliance calendar that tracks:
- BTRC renewal (due annually by February 28)
- LA County license renewal
- Industry-specific permit renewals
- State Statements of Information (every two years for LLCs and corporations)
- FBN renewal (every five years in LA County)
Periodically review whether your business activities, business location, and classifications still match current operations. If you've added new services or changed your business address, update your registrations promptly to avoid penalties.
Your next step: assemble all your business information-structure, name, address, planned activities, and whether you'll have employees. Then work through registrations in sequence: choose structure, lock in your name, file with the state if needed, obtain your identification number, register with the city or county, and secure any industry-specific permits. Planning ahead saves you from the costly delays that trip up new business owners every year.
