How to Start a Business in Riverside, California

Riverside is where the math works.

You need warehouse space. You need workers. You need to be close to the ports of Los Angeles and Long Beach. You don’t want to pay $8,000 a month for a 2,000-square-foot office in Santa Monica. Riverside solves that problem.

The city of 319,190 people sits at the anchor of the Inland Empire — a region of 4.7 million people that’s quietly become one of California’s economic engines. Manufacturing, logistics, healthcare, and research-driven innovation are booming here. Nike operates a massive facility in Riverside. So do Tesla, Procter & Gamble, Philips, and Sherwin-Williams. This isn’t a side market. It’s where real businesses operate.

And the cost structure? Commercial rent runs 40 to 60 percent lower than comparable space in Orange County or LA’s Westside. Your sales tax is 8.75 percent — a full three points below Santa Monica. These aren’t rounding errors. For a retail business doing $1 million in annual sales, Riverside’s tax rate saves your customers $20,000 per year compared to Santa Monica.

If you’re evaluating where to start or expand a business in California, Riverside deserves serious consideration. Here’s exactly what it takes to launch here.

Why Start a Business in Riverside?

Riverside is California’s 12th-largest city. That fact alone matters — you’re not operating in a small town. You’re in a mid-sized metro area with genuine economic depth.

The population has grown consistently. As of 2024, Riverside sits at approximately 319,190 residents, up from 315,534 at the 2020 census — a gain of 3.91 percent in four years. Annual growth is modest at 0.63 percent, but the trajectory is positive. More people means more customers, more workers, and more reasons for suppliers and service providers to set up shop.

The median household income is $91,045. That’s lower than coastal California — Santa Monica’s median household income is roughly $95,000, and Orange County averages around $95,000. But Riverside’s lower income pairs with dramatically lower cost of living. Your rent is cheaper. Labor costs are lower. Your operating expenses shrink.

UC Riverside and the Research Economy

UC Riverside is one of the region’s largest employers and a genuine driver of innovation. The university operates the 56-acre University Research Park (URP), which functions as an incubator and hub for technology, biotech, engineering, and advanced manufacturing companies. If your business is in a research-adjacent field — materials science, robotics, environmental tech, biotech — proximity to UC Riverside and its networks, graduate talent pipeline, and research facilities is a concrete advantage.

The university brings steady, professional-wage employment to the region. It attracts researchers, engineers, and skilled workers who might otherwise leave the Inland Empire for coastal California.

Manufacturing and Logistics: The Real Story

Manufacturing is the backbone. The Inland Empire region has 94,500 manufacturing jobs as of November 2024. Nike operates a major footwear and apparel facility in the area. Tesla runs battery and vehicle manufacturing operations regionally. Procter & Gamble, Philips, and Sherwin-Williams all have significant manufacturing or distribution operations here.

This isn’t smoke. These are Fortune 500 companies choosing Riverside and the broader Inland Empire because the economics make sense.

Logistics is even bigger. Riverside’s position is perfect for distribution: I-10, I-15, I-215, and SR-91 crisscross the region. Ontario International Airport is an hour away. The ports of Los Angeles and Long Beach are 60 miles south. Amazon has transformed the region into a distribution powerhouse. If you need a warehouse, if you ship goods, if you’re in the supply chain business, Riverside is the natural hub.

Healthcare employment is also substantial — 293,800 jobs regionally in healthcare and social assistance. Kaiser Permanente, Abbott, Optum, Dignity Health, and Providence operate major facilities in Riverside and the surrounding region. If you’re in healthcare services, medical device manufacturing, or health tech, the regional concentration of providers and employers creates customer density and talent availability.

Other major employers include Bourns (electronics), California Baptist University, Riverside Community Hospital, and the County of Riverside government offices.

The Cost Advantage

Here’s where Riverside’s appeal sharpens.

Commercial real estate costs a fraction of what you’d pay for equivalent space in coastal California. A 2,000-square-foot office in downtown Riverside might run $1,800 to $2,400 per month. The same space in downtown Los Angeles or Orange County costs $4,000 to $6,000. Warehouse space follows the same pattern.

For a business that needs 10,000 square feet of warehouse or light industrial space, the difference is not $200 per month — it’s $2,000 to $3,000 per month. Over a year, that’s $24,000 to $36,000 in rent savings. That money goes into payroll, equipment, or profit.

Labor costs reflect the lower median income. Skilled workers — engineers, software developers, managers — command similar salaries regionally as they do on the coast. But entry-level and semi-skilled positions have lower wage expectations. Your warehouse staff, administrative support, and customer service teams will cost less to hire and retain than in high-cost areas.

Step 1: Choose Your Business Structure

Your first legal decision is entity type. California’s state-level costs are identical whether you’re in Beverly Hills or Riverside — the savings come at the local level, through rent and labor. But you still need to choose the right structure.

LLC

An LLC (Limited Liability Company) is the most common choice for small and mid-sized businesses. You get liability protection — your personal assets are generally shielded from business debts or lawsuits — while maintaining flexibility on taxation and minimal administrative burden.

Filing an LLC in California costs $70. You submit the Articles of Organization (Form LLC-1) through the Secretary of State’s online filing system at bizfileOnline.sos.ca.gov. The process takes a few days, and you can file online from anywhere.

But here’s the catch that surprises many new business owners: California charges an $800 annual Franchise Tax to every LLC doing business in the state. This is separate from income tax and city business taxes. It’s due by the 15th day of the 4th month after you file your formation documents (so mid-May for most startups), then every April 15 after that. There’s no first-year exemption anymore — AB 85 expired at the end of 2023.

If your LLC’s gross income exceeds $250,000, you also pay an additional LLC fee on top of the $800 base. The tiers are:

$250K–$500K: $900 additional
$500K–$1M: $2,500 additional
$1M–$5M: $6,000 additional
$5M+: $11,790 additional

You’ll also need to file a Statement of Information (Form LLC-12) within 90 days of formation, then again every two years. This form costs $20 and updates the state on your registered agent and business address.

Corporation

If you’re raising venture capital or planning to have multiple shareholders, a C Corporation might make sense. The filing fee is $100. Corporations face more administrative requirements — annual shareholder meetings, minutes, formalities — and they’re subject to corporate income tax, which can lead to double taxation (the corporation pays tax, then shareholders pay tax on dividends).

For most small businesses, an LLC is simpler and more tax-efficient.

Sole Proprietorship

If you operate as a sole proprietor with no business entity, you have no liability protection — creditors can come after your personal assets. You also can’t hire employees as easily. There’s no state filing fee, but the trade-off isn’t worth it for any business beyond a one-person service operation.

Step 2: Register for State Taxes

Once you’ve chosen your structure, you need to register with California’s tax agencies.

Seller’s Permit

If you sell tangible goods — retail products, manufactured items, anything physical — you need a Seller’s Permit from the California Department of Tax-Fee Administration (CDTFA). It’s free to register. You apply online at cdtfa.ca.gov.

The permit lets you buy goods without paying sales tax (you’ll collect sales tax from customers instead). If you don’t have a permit and you’re selling tangible goods, you’ll pay sales tax on your inventory purchases, then collect it again from customers. That’s a disaster for margins.

EIN

You need an Employer Identification Number (EIN) from the IRS. It’s free. You apply online at irs.gov/ein. An EIN is your business’s tax ID number — banks, vendors, and the government use it to identify your company. Even if you’re a sole proprietor, an EIN keeps your personal social security number off business documents.

EDD Registration

If you hire employees, you must register with the California Employment Development Department (EDD) for payroll taxes. This is non-negotiable. California requires you to withhold and remit state income tax, disability insurance, and unemployment insurance.

AB5 Compliance

California’s AB5 law makes it very difficult to classify workers as independent contractors. The default assumption is that anyone working for you is an employee, with all attendant payroll taxes and benefits requirements. There are narrow exceptions (the “ABC test”), but they’re strict. If you’re planning to hire freelancers or contractors, understand this law now. Misclassification can cost you back taxes, penalties, and liability.

Step 3: Get Your Riverside Business Tax Certificate

This is Riverside-specific, and it’s where local costs begin.

Riverside doesn’t call it a “business license.” It calls it a “business tax.” But it functions as both: it’s a license to operate in the city, and it’s a recurring tax based on your business type and size.

Every person or company conducting business in Riverside must pay this tax. No exceptions. It applies to retail stores, service businesses, online retailers operating from a Riverside location, manufacturers, contractors — everyone.

You apply online at riversideca.gov/businesstax or in person at:

Finance Department — Business Tax & License
3900 Main Street, 3rd Floor
Riverside, CA 92522
Phone: (951) 826-5465
Fax: (951) 826-2356

The tax is calculated based on your business classification. Riverside uses different metrics depending on your type: gross receipts, number of employees, number of vehicles, number of machines, or other factors.

A small retail business might be classified as “Retail — Other” and taxed on gross receipts. A warehouse operation might be classified on the basis of square footage or employees. A consulting firm might pay a flat fee. A contractor might pay based on the number of vehicles.

Base rates start at approximately $100 for small businesses. But you need to contact the Finance Department or use their online calculator to determine your exact rate. The cost varies significantly by classification, so don’t assume the minimum applies to you.

The process is straightforward: you provide your business information, classification, and estimated gross receipts or employee count. The city calculates your tax. You pay online or by mail. Your certificate arrives within days.

Renew it annually. Failure to maintain a current certificate can result in fines or business closure.

Sales Tax: 8.75%

Riverside’s combined sales tax rate is 8.75 percent. This is one of the city’s genuine competitive advantages.

The breakdown is:

6.0% California state sales tax
0.25% Riverside County surtax
1.0% Riverside city surtax
1.5% special district tax

For comparison:

Santa Monica: 10.75%
Pasadena: 10.5%
Santa Ana: 9.25%
Irvine: 7.75%

That two-point spread between Riverside (8.75%) and Santa Monica (10.75%) is not cosmetic. For a retail business with $1 million in annual sales, customers in Riverside pay $20,000 less in sales tax than customers in Santa Monica. Some of that tax savings gets absorbed by the business as a competitive advantage; some passes to customers as lower prices.

If you’re selling goods in Riverside, your Seller’s Permit (obtained from the CDTFA) lets you collect this tax from customers and remit it to the state and local agencies monthly or quarterly.

The Inland Empire Advantage

Beyond the specific Riverside costs, you’re operating in the Inland Empire — and that context matters.

Real Estate and Space

Commercial office space in Riverside costs 40 to 60 percent less than comparable space in Orange County or LA’s Westside. A premium office building in downtown Riverside rents for $1.50 to $2.00 per square foot per month. In Irvine or Santa Ana, you’re paying $2.50 to $3.50. In West LA or Santa Monica, you’re paying $4.00 to $6.00.

Warehouse space follows the same pattern. Inland Empire logistics real estate is cheaper because land is cheaper, and because the region has abundant inventory. You’re not competing for scarce coastal space.

Labor and Wages

The median household income of $91,045 translates to lower wage expectations for non-specialized roles. If you’re hiring warehouse workers, administrative staff, or customer service representatives, your wage costs will be lower than in high-cost areas.

But this advantage is eroding. As the Inland Empire has grown and attracted major employers, competition for skilled workers has intensified. You won’t find a shortage of engineers or software developers willing to work in Riverside at coastal California salaries — those professionals have options. The wage gap is narrowest for specialized, high-skill roles and widest for entry-level and semi-skilled positions.

Logistics and Transportation

Riverside’s position is unmatched for distribution and supply chain operations. I-10, I-15, I-215, and SR-91 provide direct access to every direction. The region is 60 miles from the ports of Los Angeles and Long Beach, the largest container ports on the West Coast. Ontario International Airport is an hour away.

If your business relies on moving goods — warehousing, distribution, 3PL operations, freight, e-commerce fulfillment — Riverside’s infrastructure is purpose-built for you. Amazon didn’t build massive fulfillment centers in the Inland Empire by accident. The region’s highway access and port proximity create unmatched logistics efficiency.

The Trade-Offs

Riverside is not a coastal destination. Consumer spending power per household is lower. A luxury retail business or high-end service business will struggle with foot traffic and local customer wealth.

The region still carries a reputation as a pass-through — people driving to Las Vegas or Arizona, not a place to visit. That’s changing, slowly. Downtown Riverside has invested in revitalization, and the region is gradually building a local identity beyond logistics.

But if your business relies on local walk-in traffic and high consumer spending, you need to acknowledge this reality. Riverside is optimal for manufacturers, warehouses, distribution centers, and B2B service businesses. It’s less ideal for premium retail or luxury services dependent on high household income.

Costs at a Glance

Here’s what you’ll pay to start a basic LLC-structured business in Riverside:

Item	Cost	Timing
LLC Articles of Organization (Form LLC-1)	$70	One-time, at filing
Franchise Tax (annual, to FTB)	$800	Due April 15 each year
Statement of Information (Form LLC-12, biennial)	$20	Every two years
Business Tax Certificate (varies by classification)	~$100–$500+	Annually; contact Finance Dept. for exact rate
Seller’s Permit (if selling tangible goods)	Free	One-time, online
Combined sales tax rate	8.75%	Ongoing, collected from customers

Total first-year government fees for a basic LLC: approximately $990 to $1,390, not including the business tax certificate (which varies by your specific classification and gross receipts).

This is before any business expenses — office rent, equipment, payroll, inventory, insurance. But it’s the baseline regulatory cost to operate legally in Riverside.

The Takeaway

Starting a business in Riverside makes financial sense if you need space, logistics access, and labor without paying coastal California prices. The $800 annual Franchise Tax and 8.75 percent sales tax are real costs, but they’re offset by rent savings, lower wages for non-specialized roles, and access to the region’s manufacturing and logistics ecosystem.

UC Riverside and the surrounding research community add another layer: if you’re in an innovation-adjacent field, the talent pipeline and research infrastructure are genuine advantages.

The Inland Empire isn’t a consolation prize for businesses priced out of coastal California. Nike, Tesla, and Procter & Gamble aren’t operating here because they couldn’t afford Santa Monica. They’re here because the economics, the infrastructure, and the labor market make sense for their operations.

If that math aligns with your business, Riverside is worth a serious look. Start by registering your business entity with the Secretary of State, register for state taxes, and then contact Riverside’s Finance Department for your business tax classification and rate. From there, you’re legal and operational.
