How to start a business
in San Jose.
San Jose is the capital of Silicon Valley and the largest city in the Bay Area. Here is the practical sequence to register, get your Business Tax Certificate, and open, with the official links and where to get free help.
San Jose is the tenth-largest city in the country and the civic heart of Silicon Valley. Behind the technology headquarters is one of the most diverse populations anywhere and a deep base of local and family businesses. From the downtown core and San Pedro Square Market to Santana Row, the SAP Center, The Tech Interactive, and the Municipal Rose Garden, the city blends a global tech identity with a strong neighborhood economy.
That scale and that diversity are the opportunity. Getting open cleanly, with the right Business Tax Certificate and permits, sets the foundation. Getting found by customers comes next. This guide covers the first in detail, then points you to the second at the end.
//The sequence
How to start a business in San Jose, step by step.
This is the order that works for most new San Jose businesses. When in doubt, run your address and business type through CalGold and it will list everything that applies to you.
- 1
Register the business and the name
Form your LLC or corporation with the California Secretary of State through bizfile, or stay a sole proprietor. If you operate under a name that is not your legal name, file a fictitious business name (DBA) with the Santa Clara County Clerk-Recorder, then publish it.
- 2
Get your free EIN and any seller's permit
Get a free federal EIN from the IRS for banking and taxes. If you sell or lease physical goods, register for a free seller's permit with the CDTFA so you can collect sales tax.
- 3
Get your San José Business Tax Certificate
San José requires a Business Tax Certificate within 90 days of starting business. It is a receipt for paying the business tax, and the city is clear that it does not by itself grant zoning, fire, occupancy, or other permit approvals, which you handle separately.
- 4
Confirm zoning and pull any industry permits
Confirm your location is zoned for your use before you sign a lease, then check CalGold for the permits your trade needs. Any food business also needs plan review and an operating permit from Santa Clara County Environmental Health.
- 5
Budget for the $800 California franchise tax
If you form an LLC or corporation, California charges a minimum $800 annual franchise tax through the Franchise Tax Board, owed even in a slow year. Plan for it from day one.
- 6
Use the free help that already exists
The Silicon Valley SBDC, part of the Norcal SBDC network, offers no-cost, confidential one-on-one advising on planning, funding, and marketing. Use it before you pay a consultant.

//By trade in San Jose
Common San Jose businesses, and the extra step each needs.
Tech, hardware, or startup
Most need the Business Tax Certificate plus any state license. The harder early work is standing out and being found among a dense field of well-funded Silicon Valley neighbors.
Restaurant or food business
San Jose's diverse food scene is busy and competitive. Beyond the tax certificate, you need plan review and a permit from Santa Clara County Environmental Health, so engage them before you design the kitchen.
Retail or storefront
Get a CDTFA seller's permit to collect sales tax plus the tax certificate. In centers like Santana Row and downtown, confirm signage and use rules with the city first.
Home-based or service business
Home-based businesses still need the Business Tax Certificate. Confirm your use is allowed at your address, and remember the certificate is not the same as zoning or occupancy approval.
//When you are ready to be found
Getting open is step one. Getting found is step two.
A dense market rewards being found
Silicon Valley is crowded with capable competitors. Being the business people actually find when they search is what turns that density into customers.
Local search is the front door
Most first customers come from a Google search or the map pack. A complete profile, real reviews, and a fast site do most of the work.

//Common questions
Things we get asked first.
Do I need a business license in San Jose?
San Jose issues a Business Tax Certificate rather than a license, and you must register for one within 90 days of starting business. Keep it posted at your place of business. Note that the certificate is a tax receipt and does not by itself grant zoning, fire, or occupancy approvals.
How do I open a restaurant in San Jose?
Beyond the Business Tax Certificate, every food facility needs plan review and an operating permit from Santa Clara County Environmental Health, which inspects all restaurants in the county. Start with plan review early, because it shapes your build-out and timeline.
Where do I file a DBA for a San Jose business?
File a fictitious business name with the Santa Clara County Clerk-Recorder if you operate under a name that is not your legal name, then publish it in a local newspaper.
What is the $800 tax people forget about?
If you form an LLC or corporation, California charges a minimum $800 annual franchise tax through the Franchise Tax Board, owed even in a slow year. New owners routinely forget it, so plan for it from day one.
Can you guarantee customers once I open?
No, and anyone who guarantees rankings or a fixed number of leads is selling fiction. We promise honest work and reporting tied to revenue, and we make you the findable option when a San Jose customer searches.
About Mining Wells
We're on a mission to fix bad marketing.
Maybe:
- You are spending thousands on marketing tools, ads, and your website, with zero revenue increase to show for it.
- Every campaign you have tried gets minimal results.
- You have a great product that nobody seems to find.
- You are getting interest, but it never converts to a sale.
- You have a low retention rate.
- You have been paying a marketing agency for over a year and have not seen results.
You are not alone. Many founders and leaders live with the results of bad marketing without ever finding the reason.
And often that is because it can be many reasons. Sometimes it is the wrong ICP, sometimes the wrong messaging, sometimes the wrong targeting chasing impressions.
We are here to take the hard guesswork out and provide that clarity before it is too late.
At Mining Wells, we help founders and leaders grow their businesses the right way.
