How to Start a Business in Los Angeles, California

Why LA’s Business Setup Has Two Layers (and Two Bills)

Los Angeles is the second-largest city in the United States, with approximately 3.9 million people inside city limits and a metro area of over 13 million. The economy spans entertainment, technology, fashion, food, aerospace, healthcare, and professional services — and nearly every one of those sectors generates opportunities for new businesses. But starting a business here means dealing with two completely separate government systems, each with its own portal, deadlines, and fees. Understanding this upfront saves you from the most common mistake new LA business owners make.

Layer one is the state. You file your business entity with the California Secretary of State ($70 for an LLC) and pay the $800 annual franchise tax to the Franchise Tax Board. These obligations apply to every business in California regardless of city.

Layer two is the city. Los Angeles requires every person engaging in business within city limits to register for a Business Tax Registration Certificate (BTRC) through the Office of Finance. This is LA-specific — it doesn’t exist in unincorporated LA County, and neighboring cities like Burbank or Glendale have their own systems.

These two layers don’t talk to each other. Filing with the Secretary of State does not register you with the LA Office of Finance. Getting your BTRC does not file your state taxes. They’re separate portals, separate accounts, separate deadlines, and separate bills.

The trap most new entrepreneurs fall into: they file their LLC with the state, get their EIN, open a bank account, start operating — and six months later receive a notice from the LA Office of Finance asking why they haven’t registered. By then, late penalties may have started accruing.

The fix is straightforward. Handle both layers in the same week. Here’s how.

Step 1 — File Your Entity with the California Secretary of State

Every formal business entity in California — LLC, corporation, or limited partnership — must register with the Secretary of State (SOS).

LLC Formation (most common for new businesses):

File Articles of Organization (Form LLC-1) for $70
File online at bizfileOnline.sos.ca.gov
Processing time: online filing typically takes 3-5 business days
You’ll receive a stamped copy of your Articles with your entity number

Corporation Formation:

File Articles of Incorporation for $100
Same portal: bizfileOnline.sos.ca.gov

Statement of Information (required follow-up):

File Form LLC-12 within 90 days of formation, then every two years
Filing fee: $20
This updates the state on your business address, agent, and management structure

Registered Agent Requirement:

Every California LLC and corporation must designate a registered agent with a physical California address
PO Boxes don’t qualify
You can serve as your own agent if you have a physical address in the state
If you don’t have an office, registered agent services run $50-200 per year

Name Availability:

Free name search at businesssearch.sos.ca.gov
Optional name reservation: $10, holds your name for 60 days
Your LLC name must include “LLC” or “Limited Liability Company”

For a standard single-member LLC, the entire SOS filing process takes about 20 minutes online. Skip the $500 lawyer unless your situation involves unusual partnership structures or intellectual property assignments. A formation service handles the same paperwork for $0-39 plus the state fee.

One thing to keep in mind about California’s business entity system: the Secretary of State’s database is public. Anyone can search your LLC name and see your registered agent address at businesssearch.sos.ca.gov. If you’re using your home address as your registered agent address, that information is publicly accessible. This is one practical reason many home-based business owners in LA use a registered agent service — privacy, not just convenience.

Step 2 — Get Your EIN and Handle State Tax Registration

Federal Employer Identification Number (EIN):

Free from the IRS at irs.gov
Takes about 10 minutes to complete online
You’ll receive your EIN immediately upon completion
Required for opening a business bank account, hiring employees, and filing taxes

California Franchise Tax ($800/year):

Every LLC doing business in California pays $800 per year to the Franchise Tax Board (FTB)
Due by the 15th day of the 4th month after formation (first year), then April 15 annually
The AB 85 first-year exemption expired December 31, 2023 — you pay the $800 from day one now
This is separate from and in addition to your LA city business tax
LLCs with gross income over $250K pay an additional LLC fee: $900 ($250K-$500K), $2,500 ($500K-$1M), $6,000 ($1M-$5M), $11,790 ($5M+)

Seller’s Permit (if selling tangible goods):

Required for any business selling physical products in California
Register free at cdtfa.ca.gov through the California Department of Tax and Fee Administration
Los Angeles combined sales tax rate: 9.75% (state + county + city + district)

Employer Registration (if hiring):

Register with the Employment Development Department (EDD) for payroll tax
California requires unemployment insurance, employment training tax, state disability insurance, and personal income tax withholding
AB5 rules on independent contractor vs. employee classification are strictly enforced — misclassification penalties are steep

California state income tax: The state’s progressive income tax tops out at 13.3%, the highest in the nation. Your business income flows through to your personal return (for LLCs and S-corps), so factor state income tax into your profit projections. There’s no separate state business license — California handles business licensing at the city level, which is why the LA BTRC in the next step exists.

CalOSHA: California has its own workplace safety agency (Cal/OSHA), separate from federal OSHA. If you’re hiring employees, familiarize yourself with Cal/OSHA requirements — they’re generally stricter than federal standards, particularly around heat illness prevention, which matters in LA’s San Fernando Valley where summer temperatures regularly exceed 100 degrees.

CCPA compliance: If your business handles consumer data and meets certain thresholds (over $25 million in annual revenue, or buying/selling data of 100,000+ consumers), the California Consumer Privacy Act (CCPA) applies. Most startups won’t hit these thresholds immediately, but build your data handling practices with CCPA in mind from the start.

Step 3 — Register for Your LA Business Tax Registration Certificate

This is where Los Angeles diverges from every other California city. The BTRC system is unique to LA and significantly more complex than what you’ll find in San Diego, San Jose, or Sacramento.

Who must register: Every person engaging in business within LA city limits. This includes home-based businesses, sole proprietors, freelancers, and independent contractors. There are almost no exceptions.

The boundary trap: Before you register, verify that your business address is actually inside LA city limits. This sounds obvious, but Los Angeles has one of the most irregular city boundaries in the country. Some zip codes — like 90045 (Westchester) and 90066 (Mar Vista) — are only partially inside city limits. Your neighbor across the street might be in unincorporated LA County and not need a BTRC at all. Use the LA city boundary tool to check your specific address before registering.

The 7-day rule: Even if your business is based outside LA, performing work within city limits for 7 or more days per year triggers the registration requirement. If you complete 4 or more transactions in LA, that also triggers it.

How to register:

Go to latax.lacity.org (the Office of Finance online portal)
Create an account and complete the registration form
You’ll need: legal name, DBA, business address, SOS entity number, EIN, NAICS code, and start date
Registration itself costs nothing upfront — the tax is assessed based on your prior-year gross receipts
First-year businesses report estimated receipts for the current year

The registration process is straightforward online. The complexity comes in the next step: figuring out what you actually owe.

Step 4 — Understand Your Business Tax Classification

This is where LA gets complicated. Most cities charge a flat fee or a simple percentage. Los Angeles taxes by business classification, with more than 40 classification codes, each carrying its own rate.

The most common classifications:

Classification	Rate
Professions & Occupations (catch-all)	$4.25 per $1,000 of gross receipts
Retail sales	$1.32 per $1,000 (inside-city sales)
Wholesale	$1.05 per $1,000
Multimedia businesses (Hollywood Multimedia)	$1.01 per $1,000
Contractors	$153 flat for first $60,000, then $1.01 per $1,000 on excess

Rates across all classifications range from 0.1% to 6.0%.

How the math works: The rate is applied per $1,000 or fractional part of $1,000 in gross receipts. This is not a simple percentage calculation. You round your gross receipts up to the next $1,000, divide by $1,000, and multiply by your per-$1,000 rate.

Example: A consultant (Professions & Occupations) with $150,000 in gross receipts: $150,000 / $1,000 = 150 units x $4.25 = $637.50 in annual city tax.

The 80% rule: If 80% or more of your gross receipts come from a single business activity, you can report all of your receipts under that one classification rate. This simplifies reporting for businesses that have minor secondary activities.

Looking up your classification: The complete rate table and classification guide is at finance.lacity.gov/tax-information-booklet. Finding your correct classification is worth the time — the wrong one can mean overpaying by thousands of dollars.

Multiple classifications: Some businesses perform activities that span more than one classification. A design agency that also sells physical merchandise is potentially in both Professions & Occupations and Retail. If the 80% rule doesn’t apply (because neither activity dominates), you’ll report receipts under each applicable classification at its respective rate. This is where LA’s system gets genuinely complex — and where a tax professional familiar with the BTRC system earns their fee.

Contractors get a unique deal: The contractor rate is $153 flat for the first $60,000 in gross receipts, then $1.01 per $1,000 on everything above that. For a contractor doing $200,000 in gross receipts: $153 + (140 x $1.01) = $294.40. That’s significantly less than the Professions & Occupations rate on the same revenue ($850). If you’re a contractor, make sure you’re classified correctly.

Step 5 — Check If You Qualify for an Exemption

Here’s the part most guides bury at the bottom, even though it’s the most relevant section for new business owners.

Small Business Exemption: If your worldwide gross receipts are $100,000 or less, you’re exempt from paying the business tax entirely. You still have to register and file your annual return — but the tax amount is zero. For most brand-new businesses, this means you pay nothing to the city in your first year (and possibly your second).

Creative Artist Exemption: If you earn $300,000 or less from qualifying creative activities — writing, directing, performing, producing, music composition — you qualify for the creative artist exemption. In a city where half the population has a screenplay in progress, this is a genuinely useful provision. The threshold is three times the standard small business exemption.

Critical deadline: Both exemptions require filing by the annual deadline — March 2, 2026 (because February 28 falls on a Saturday). Miss the filing deadline and you lose the exemption for that year, even if your receipts clearly qualify you. This catches people every year. Set a calendar reminder for February.

Nonprofit exemption: 501(c)(3) organizations are exempt from the business tax but still must register for a BTRC.

Key Deadlines and Penalties

LA’s business tax calendar runs on a January-through-February cycle, not the typical calendar or fiscal year.

Tax period: Based on prior calendar year’s gross receipts
Due date: January 1 of each year
Delinquent after: Last day of February (March 2, 2026 because Feb 28 is Saturday)
Late interest: 0.7% per month on unpaid tax, starting March 3
Late penalties escalate fast:
- 5% penalty starting March 3
- 10% starting April 1
- 15% starting May 1
- 20% starting June 1
- 40% starting July 1

That penalty structure means waiting until summer to file an overdue return costs you 40% on top of what you owe. Don’t delay.

AB 63 data sharing: The Franchise Tax Board now shares tax data with the LA Office of Finance. If you’re registered with the state but not with LA, the city will find you. The days of flying under the radar are effectively over. Register proactively — it’s cheaper than getting caught.

LA-Specific Considerations

Cost of doing business: Los Angeles is expensive, but the costs vary dramatically by neighborhood. Commercial rent in Downtown LA runs $3-5+ per square foot per month for office space. In Canoga Park or parts of the San Fernando Valley, you might find space under $2 per square foot. Venice and West Hollywood command premiums that rival parts of San Francisco. Where you locate your business matters as much as what your business does.

Minimum wage: LA’s city minimum wage is $17.87 per hour — significantly higher than the state minimum of $16.90 per hour. If you’re hiring, budget for LA’s rate, not the state rate.

Sales tax: The combined rate in LA is 9.75%. On a $100 purchase, $9.75 goes to various tax authorities. If you’re in retail, this rate affects your pricing strategy. Note that the sales tax rate includes state, county, city, and special district components — it can vary slightly depending on exactly where in LA you’re located.

Paid leave requirements: California mandates paid sick leave for all employees. As of 2024, employers must provide at least 40 hours (or 5 days) of paid sick leave per year. California also has a paid family leave program through the EDD, funded by employee payroll deductions. These aren’t optional — build them into your employee cost calculations.

The BTRC is not an income tax: LA’s business tax is based on gross receipts, not profit. That distinction matters. A business that grosses $500,000 but nets $30,000 still pays tax on the full $500,000 in receipts. There’s no deduction for expenses, cost of goods, or losses. For high-revenue, low-margin businesses (restaurants, retail), this can feel disproportionate.

Key industries in LA: Entertainment, technology, fashion, food and beverage, professional services, real estate, healthcare, and manufacturing. Major employers include Disney, NBCUniversal, Kaiser Permanente, and Cedars-Sinai — each generating extensive contractor and vendor ecosystems that small businesses can tap into.

What It Actually Costs to Start a Business in LA (Worked Example)

Numbers cut through confusion. Here’s what a typical new business actually pays.

Scenario A: Solo consultant, LLC, $150K gross receipts

Cost	Amount
SOS filing (Articles of Organization)	$70
Statement of Information	$20
EIN	Free
Registered agent service	$100-200/year
Franchise tax (state, FTB)	$800/year
BTRC (Professions & Occupations): 150 x $4.25	$637.50/year
Total year-one government costs	~$1,528-1,628

Scenario B: Solo freelancer, LLC, $80K gross receipts (under $100K exemption)

Cost	Amount
SOS filing	$70
Statement of Information	$20
EIN	Free
Registered agent service	$100-200/year
Franchise tax (state)	$800/year
BTRC city tax	$0 (exempt — under $100K)
Total year-one government costs	~$890-990

The difference between those two scenarios is the $100K small business exemption in action. For most brand-new businesses that don’t hit six figures in year one, the city tax is zero. The $800 state franchise tax is the cost you can’t avoid.

What these numbers don’t include: Commercial rent, insurance, equipment, professional services (accountant, lawyer), and marketing. Those operational costs vary enormously based on your business type and neighborhood. A home-based consulting practice might need $2,000 to launch. A restaurant in Silver Lake might need $200,000+.

The government costs are knowable and predictable. Build them into your startup budget, set your filing reminders for February (city) and April (state), and focus your energy on the business itself.

Picking the Right Neighborhood for Your Business

LA is not one market — it’s dozens of micro-markets, each with different customer demographics, commercial rent levels, foot traffic patterns, and competitive dynamics.

Downtown LA (DTLA): The revitalized core has attracted tech companies, creative agencies, and upscale restaurants. Commercial rents are higher than the city average but lower than the Westside. The Arts District within DTLA has become a hub for design studios, galleries, and trendy food concepts.

Hollywood and West Hollywood: Entertainment industry adjacency, nightlife, and tourism. High visibility but high rents and intense competition for food and retail.

Venice and Santa Monica (adjacent to LA): Note that Santa Monica is a separate city with its own business license. Venice is within LA city limits. The “Silicon Beach” tech cluster in Venice and Playa Vista has created demand for co-working spaces, lunch spots, and professional services.

San Fernando Valley: The Valley covers a huge geographic area with diverse neighborhoods ranging from Encino (affluent, family-oriented) to Van Nuys (commercial, affordable) to Burbank (separate city — not subject to BTRC). Commercial rent in the Valley is typically 30-50% less than the Westside.

South LA: Growing entrepreneurial activity with city investment in business development. Lower commercial rents than most of the city, with a customer base that’s been historically underserved by retail and services.

Where you locate determines your rent, your customer base, your competition, and (if you’re in a zip code that straddles city limits) whether you even need a BTRC. Get the location decision right, and the rest of your LA business planning follows from it.
