How to Start a Business in Pasadena, California

Pasadena has a reputation: old money, tree-lined streets, the Rose Bowl, the Tournament of Roses. What most people don’t see is the city underneath. Caltech and its Jet Propulsion Laboratory employ over 8,000 people. Parsons Corporation and Tetra Tech run their headquarters from here. East West Bank anchors a growing financial sector. Over 60% of the city’s workforce works in professional, managerial, technical, or specialized roles. This is a science and technology city dressed up as a charming suburb.

That distinction matters when you’re starting a business. Pasadena’s tax structure, its proximity to research institutions, and its affluent, educated population create specific advantages—and specific costs. This guide walks you through what it actually takes to launch a business here, from state filing to your city license, and what makes Pasadena different from starting in downtown LA or elsewhere in the San Gabriel Valley.

Why Start a Business in Pasadena?

Pasadena is home to roughly 135,000 people, a figure that has declined slightly at -0.4% annually from the 2020 census count of 139,373. Despite that modest contraction, it remains one of the largest and most economically significant cities in the San Gabriel Valley. More important: the people who live and work here have money and specialized skills.

The median household income is approximately $105,192 as of 2024—above both California’s state median and the national median. That matters for a business. It means your potential customer base has disposable income. It means your potential employees expect professional-level compensation. It shapes what market you can serve.

The city’s economy is anchored by Caltech, which operates as the single largest employer with roughly 8,000 employees. That number includes approximately 5,500 people working at the Jet Propulsion Laboratory (JPL), which Caltech operates under a NASA contract. JPL isn’t just a research facility—it’s an economic engine. Scientists, engineers, project managers, administrative staff, contractors. They live in Pasadena or nearby. They spend money locally. They need services.

Beyond Caltech and JPL, major employers include Parsons Corporation (infrastructure and defense, headquartered here), Tetra Tech (environmental engineering, also headquartered here), East West Bank, and Kaiser Permanente. These aren’t small operations. They’re mid-to-large firms with hundreds of employees each.

The composition of Pasadena’s roughly 100,000-person labor force tells you something about who works here and what they do. Over 60% are employed in professional, managerial, technical, sales, and clerical positions. That’s not retail and hospitality. That’s knowledge work. Engineering. Analysis. Planning. Specialized services. If you’re launching a B2B tech company, a consulting firm, or a service business targeting educated professionals, Pasadena’s workforce profile aligns directly with your potential market.

Tourism adds another layer. The Rose Bowl Stadium and the annual Tournament of Roses Parade drive significant hospitality and retail revenue. If you’re in hospitality, event services, or tourism-adjacent business, there’s real demand. But this city’s economy isn’t tourism-dependent. Tourism is supplementary revenue on top of a base built on brainpower.

What ties it together is the innovation infrastructure. Caltech and JPL don’t just employ people. They generate research, spin off companies, and create networks of engineers and scientists with problems to solve and budgets to solve them with. Pasadena fosters a supportive environment for technology and innovation companies specifically because of this proximity to research institutions. If your business serves that ecosystem—materials science, software, data analysis, hardware development—you’re in the right city. If you’re launching something unrelated, you’re still in a place where talent is concentrated and affluent.

Step 1: Choose Your Business Structure

Before you file anything, you need to decide what legal structure makes sense. In California, your main options are LLC, corporation, or sole proprietorship. Each has different costs, protections, and tax implications.

The LLC route is most common for startups. Here’s what it costs: $70 to file your Articles of Organization (Form LLC-1) with the California Secretary of State. You file online at bizfileOnline.sos.ca.gov. That’s the state filing fee. One-time.

Then comes the California Franchise Tax. Every LLC doing business in California pays $800 per year to the Franchise Tax Board (FTB). This is non-negotiable. You might have heard about AB 85, which provided a first-year exemption for new LLCs. That exemption expired on December 31, 2023. It’s gone. If you’re forming an LLC in 2025 or later, you owe the full $800 in your first year.

Beyond the initial formation, you’ll also file a Statement of Information (Form LLC-12) within 90 days of formation, then every two years after that. The filing fee is $20 each time. Not expensive, but a recurring obligation.

If you want to reserve your business name before filing, you can do that for $10. The reservation holds for 60 days, giving you time to finalize your formation documents.

Corporations cost more to file but might make sense if you’re raising venture capital or want a different tax structure. The Articles of Incorporation filing fee is $100. Like an LLC, a corporation also pays the $800 franchise tax to California (plus additional fees if your gross income exceeds $250,000). Most startups don’t choose the corporation route for the first few years.

Sole proprietorship requires no state filing. You can technically start a business operating under your own name without filing anything with the state. The catch: you have no liability protection. Your personal assets are exposed if the business gets sued. For most people, an LLC is worth the $70.

One thing that doesn’t change with your choice of structure: California’s top income tax rate of 13.3%. It’s the highest in the nation and applies regardless of which city you operate in. Pasadena doesn’t change this. It’s a state-level cost you’ll bear no matter where in California you set up.

Step 2: Register for State Taxes

Filing your formation documents is only the beginning. You need to register with California’s tax agencies and the IRS before you operate.

If you’re selling tangible goods, you need a Seller’s Permit from the California Department of Tax-Fee Administration (CDTFA). Go to cdtfa.ca.gov. It’s free to register. No fee, no waiting period. But it’s mandatory if you sell physical products—inventory, goods, tangible items. If you skip this and get caught, you’ll face penalties. The registration is straightforward and takes minutes online.

You need an Employer Identification Number (EIN) from the IRS. Go to irs.gov/ein. It’s free. Apply online and you’ll get your number immediately. You need this even if you’re a sole proprietor with no employees—banks will ask for it when you open a business account, and the IRS wants it for tax purposes.

If you’re hiring employees, register with the California Employment Development Department (EDD) for payroll taxes. You’ll pay unemployment insurance, state income tax withholding, and other payroll obligations. This is separate from federal payroll taxes (Social Security, Medicare), which you’ll handle with the IRS. The EDD registration is free but required if you have any W-2 employees.

Understand AB5 compliance. California’s AB5 law makes it difficult to classify workers as independent contractors. In most cases, if someone is working for you, they legally must be classified as an employee with all the protections and costs that entails. There are narrow carve-outs (licensed professionals, certain business-to-business arrangements), but the default is employment. This matters because it shapes your labor costs and compliance obligations. Hiring in California is not the same as hiring in other states.

Step 3: Get Your Pasadena Business License

Once you’ve filed your state paperwork and registered for taxes, you need a city business license. This is the local requirement.

Pasadena’s Municipal Code requires a license for all businesses operating within city limits—whether for-profit or not. No exceptions. If you’re doing business in Pasadena, you need a license.

The key detail: all business license fees are paid in advance and are due prior to the operation of the business. You don’t wait until you’ve made revenue. You don’t get a grace period. You pay before you open your doors.

The Pasadena Business License Office is located at:

100 North Garfield Avenue, Pasadena, CA 91107

If you prefer to handle it by mail:

Room N106, P.O. Box 7115, Pasadena, CA 91109

You can call them at (626) 744-4166 with specific questions about your business classification or to discuss rates.

You can apply online, by mail, or in person. Online is fastest. The office staff can answer questions about which license type applies to your business and what the specific tax rate will be.

Pasadena Business License Tax: Employee-Based (Not Gross Receipts)

Here’s where Pasadena’s model diverges from other California cities—and why it matters for your costs.

Most major California cities use a gross receipts tax model. Santa Monica does this. Los Angeles does this. In those cities, your business license tax is based on how much money you bring in. More revenue, higher tax. This hits tech startups hard. A software company with $2 million in annual revenue but only three employees pays tax on that $2 million in gross receipts, regardless of profit or headcount.

Pasadena uses an employee-based business license tax model instead. Your tax is computed as a flat rate plus a per-employee charge. The actual rates vary by business classification. You need to contact the Business License Section at (626) 744-4166 to find out the specific flat rate and per-employee charge for your business type.

The real advantage: a tech startup with high revenue but low headcount saves money. A software company generating $2 million in revenue with three employees pays far less in Pasadena’s employee-based model than it would in Santa Monica or LA’s gross-receipts model. This structure aligns the tax burden with your actual operational scale (employees) rather than your revenue.

There’s also a $1 starter rate available for qualifying new small businesses with fewer than 5 employees. This is a genuine incentive. If you’re starting out and don’t yet have a full team, Pasadena’s entry cost is minimal. That $1 starter rate isn’t going to last forever—it’s designed to help businesses get through their first year or two—but it recognizes that new, lean operations shouldn’t be crushed by licensing costs.

For comparison: a startup with two employees in Santa Monica would pay based on gross receipts from day one. In Pasadena, you might pay $1 your first year, then scale up as you hire. The difference isn’t trivial when you’re bootstrapping.

Sales Tax: 10.25% Combined

If you’re selling tangible goods in Pasadena, you collect and remit sales tax. The combined rate is 10.25% as of 2026 (rates can shift slightly year to year; verify current rates with the CDTFA).

The breakdown: 6.0% is California’s state base rate, 0.25% is the LA County add-on, 0.75% is the Pasadena city rate, and 3.5% comes from special district taxes. That totals 10.25%.

For context, this is lower than Santa Monica’s 10.75% and comparable to most of Los Angeles. It’s not the lowest rate in Southern California, but it’s reasonable.

You file and remit sales tax through the CDTFA. If you registered for a Seller’s Permit, you’re already in the system. You’ll file returns (usually monthly, depending on your sales volume) and send in the tax you’ve collected.

Costs at a Glance

Here’s what you’ll actually pay to get a basic LLC up and running in Pasadena:

LLC filing with California Secretary of State: $70 (one-time)
Franchise Tax to the FTB: $800/year (non-negotiable, even year one as of 2024)
Statement of Information (Form LLC-12): $20 every two years
Business license tax in Pasadena: Flat rate plus per-employee charge (varies by classification; $1 starter rate available for qualifying small businesses under 5 employees)
Seller’s Permit: Free (if you sell tangible goods)
EIN from the IRS: Free
Combined sales tax rate: 10.25% (collected from customers, not paid by you directly)

Total first-year government fees for a basic LLC: Approximately $900+ before you account for your Pasadena business license tax. If you qualify for the $1 starter rate, your city cost is minimal. If you’re already beyond five employees, your per-employee charges will add to that total.

The biggest variable is your Pasadena business license tax. Call (626) 744-4166 with your business type and they’ll give you the exact number. But the principle is clear: if you’re lean and high-revenue (like many tech startups), Pasadena’s employee-based model works in your favor compared to other California cities.

What Makes Pasadena Different

Starting a business in Pasadena isn’t fundamentally different from starting one in Santa Monica or downtown LA. You still file with the California Secretary of State. You still pay the $800 franchise tax. You still deal with California’s punishing income tax rate.

But three things set Pasadena apart:

First, the economy is built on brainpower, not hospitality or retail. Caltech and JPL are the foundation. That means your potential customers and employees are concentrated in technical and professional roles. If you’re launching a B2B service, a software company, or anything targeting engineers and analysts, Pasadena’s labor force composition is a built-in advantage. You’re not fighting to stand out in a sea of hospitality workers or retail services. You’re in a city where your target market already lives and works.

Second, the employee-based tax model is genuinely more favorable for startups than the gross-receipts model used in nearby cities. A two-person software company with $1.5 million in annual revenue pays $1 in Pasadena’s first year (if it qualifies for the starter rate), then scales up per employee. In Santa Monica, that same company would pay based on gross receipts. The tax burden is lower in Pasadena if you’re lean.

Third, Pasadena has a higher median household income ($105,192) than most of California. Your potential customers have more disposable income. Your potential employees expect higher salaries. Your overhead costs (rent, commercial space) are higher to match. It’s not a hidden gem for bootstrapped businesses on a razor-thin budget. It’s an expensive city to operate in. But if you’re targeting affluent professionals or serving a knowledge-worker economy, that affluence is your market.

Next Steps

You have a roadmap. The process is straightforward, even if it has multiple steps.

Start with your business structure. For most startups, an LLC is the right call. File your Articles of Organization at bizfileOnline.sos.ca.gov. Pay the $70. It takes 15 minutes.

If you’re selling products, get your Seller’s Permit from cdtfa.ca.gov. Also free, also instant.

Then contact the Pasadena Business License Office at (626) 744-4166 to find out your specific business classification and tax rate. Ask if you qualify for the $1 starter rate. Apply online or in person at 100 North Garfield Avenue. Pay your license fee in advance.

If you’re hiring employees, register with the EDD for payroll taxes.

You’ll owe the California Franchise Tax ($800) by the 15th day of the 4th month after you form your LLC. Mark that on your calendar now.

After that, you’re licensed and operational. You’ll file your Statement of Information every two years ($20), pay your franchise tax every year ($800), and file sales tax returns if you’re collecting sales tax.

Pasadena’s employee-based license tax model and $1 starter rate give you a genuine advantage if you’re building a lean, high-value operation. But you’re still operating in California, which means high income taxes, strict labor laws, and careful compliance requirements. That’s the trade-off. Pasadena gives you access to talent and an educated market. California takes its cut. Weigh that against your business model and decide if it’s worth it.

If you’re building something that serves Caltech, JPL, or the broader tech and engineering sector, Pasadena is worth considering. If you’re bootstrapping a service business on a shoestring budget, the costs might push you toward a cheaper state or city. Either way, you now have the real numbers to make that decision.
