City business license guide
Last updated: October 3, 2026
Starting a business in San José usually means more than one step. The city has a local business tax requirement. Santa Clara County may handle your fictitious business name or food permit. California may handle your seller’s permit, employer account, entity filing, or professional license. The IRS may handle your federal tax ID.
Bottom line
San José does not use the simple name “business license” for its main local requirement. The City of San José calls it a Business Tax Certificate. The City of San José Finance Department says every person or company conducting business in San José must register for a Business Tax Certificate. The city also says payment is due within 90 days of starting business in San José.
A Business Tax Certificate is not zoning approval, a building permit, a fire permit, a county health permit, a seller’s permit, a contractor license, or a professional license.
San José business changes: April 1–October 1, 2026
- City business-tax rates changed July 1, 2026. The one-to-two employee base rose from $219.60 to $222.89, and other schedules changed too. Use the current city rate table before paying.
- California bizfile access changed August 1, 2026. User Access is now required for online Statement of Information filings. New corporations, LLCs, and limited partnerships use 12-character entity IDs beginning with “B”; existing IDs stay unchanged.
- San José hotel tax changed October 1, 2026. The total Transient Occupancy Tax rose from 10% to 12% for lodging operators.
Quick start: what to check first
- Confirm your location and business activity. Write down whether you are home-based, mobile, online, storefront, food-related, construction-related, or using shared space.
- Check San José zoning before signing a lease. Use the city’s Zoning Code and the Development Services Permit Center if your use, build-out, signs, fire review, or public right-of-way work may need review.
- Register for the city Business Tax Certificate. Use the city’s Business Tax Certificate registration page. Have your start date, tax ID, owner details, San José locations, email, and other permit numbers if they apply.
- Check county and state items. Food, mobile vending, fictitious business names, seller’s permits, payroll accounts, contractors, and professional work may need separate steps.
- Keep proof. Save your certificate, receipts, emails, application numbers, renewal dates, and any zoning or permit answers you receive.

City requirement: San José Business Tax Certificate
The city’s main local registration is the Business Tax Certificate. San José says anyone or any company doing business in the city must register for it within 90 days of starting business. The city says you may hear people call it a business license or business permit, but San José calls it a Business Tax Certificate.
The certificate is issued after registration and payment. Keep it posted at your place of business when that applies.
What you need to register
The city’s registration page lists items it may ask for, including your San José business start date, tax ID, owner details, San José locations, email, contractor number if applicable, state seller’s permit number if applicable, and county health permit number if applicable.
How the city business tax is calculated
For many standard businesses, San José uses employee count. The city rate page says “employee” includes owners, family members, partners, agents, managers, solicitors, and other people engaged in the operation of the business, not just W-2 employees. Some other business types use another measure, such as rental units, square footage, mobile home park lots, or water meter connections.
The San José business tax rates page lists rates effective July 1, 2026. For many businesses, the base tax for one or two employees is $222.89, with incremental amounts for higher employee counts. Different schedules apply to residential rentals, commercial rentals, mobile home parks, water-meter connections, and out-of-town businesses. Non-exempt accounts also pay the $4 state SB-1186 fee each year. Use the current table for your category before paying.
Renewal
The city’s pay or renew page says the business tax is due annually on the 15th day of the month from when your business started. The city says you must pay or renew by the due date, even if you did not get a renewal notice.
If you move, close, add a location, change your name, or change employee count, use the city’s business tax forms page. That page links to update, closure, add or remove location, refund, exemption, and related business tax forms.
Zoning, building, fire, signs, and other city permits
A Business Tax Certificate does not clear your location or use.
Zoning and planning
San José’s Planning Division uses the city Zoning Code, also called Title 20. The city has Planning Guides for home businesses and other uses. If your business brings customers to a site, stores goods, uses equipment, makes noise, uses vehicles, handles food, or changes a prior use, check Planning before you spend money.
Home businesses
San José’s home occupation planning guide lists limits and prohibited home occupations, including food catering, most vehicle-related uses, welding, pest control, and uses requiring a Fire Department hazardous-materials permit. It also addresses sales, signage, parking, storage, and accessory buildings. Check your exact activity and address.
Building and trade work
Build-outs, tenant improvements, electrical work, plumbing, hoods, signs, accessibility work, and changes to a space may need a building permit. The city’s online permits page says Building, Planning, Fire Prevention, and Public Works offer online permits. Use the Permit Center or SJPermits to check your project path.
Fire permits and inspections
The San José Fire Department Bureau of Fire Prevention handles fire safety, hazardous materials, construction plan reviews, and inspections. The city’s Fire Prevention and Permits page is the starting point. Some businesses may also need an Operational Permit, also called an Annual Hazardous Materials Permit or Annual Fire Permit.
Signs and outdoor vending
If you plan to add a storefront sign, check the city’s Sign Code and sign permit application path before ordering the sign. If you sell outside, from a cart, truck, stand, or other mobile setup, use the city’s Outdoor Vending page. The route depends on location and operation: some private-property vending needs Planning approval, while vending on public property can require a San José Police Department permit. Food trucks and other mobile food facilities also need the applicable Santa Clara County health permit.
What does this mean for me? Your city tax certificate starts the local tax account. It does not clear the site, the use, the kitchen, the fire setup, the sign, or the health permit. If your business touches a building, food, customers, vehicles, fire safety, signs, or a home address, check permits before opening.
Santa Clara County checks
Santa Clara County steps may apply in addition to the city certificate.
Fictitious business name
If you use a business name that is not your legal name or registered entity name, you may need an FBN statement. The Santa Clara County Clerk-Recorder FBN page says the purpose of FBN registration is to let consumers access the true name and address of the owners of a business. Confirm the current filing steps, publication rules, and fees with the county before filing.
Food and retail health permits
Food businesses need extra care. Santa Clara County Department of Environmental Health covers food and retail operations. Its food and retail operations page routes fixed food facilities and other food businesses. A truck or cart should use the county’s Mobile Food Facility permit path. Food booths at fairs and similar community events use the Temporary Food Facility permit path. Cottage food and catering have separate county routes. Match the permit to how and where you actually prepare and sell food.
California state checks
California steps depend on what you sell, your entity, employees, and regulated work.
Entity filing
If you form an LLC, corporation, limited partnership, or certain other entities, use the California Secretary of State’s bizfile California portal. Effective August 1, 2026, User Access is required for online Statement of Information filings. Newly registered corporations, LLCs, and limited partnerships now receive a 12-character entity ID beginning with “B”; existing entity numbers stay the same. A sole proprietor may not need an entity filing just to start, but may still need city tax registration, FBN filing, tax accounts, and permits.
Seller’s permit
If you sell or lease tangible personal property that would normally be subject to sales tax at retail, CDTFA says you must obtain a seller’s permit when you are engaged in business in California. Use CDTFA’s seller’s permit FAQ and permits and licenses page. For a plain-English comparison, see our guide to seller’s permits vs business licenses.
Employer payroll account
If you hire employees and pay more than $100 in wages in a calendar quarter, EDD says you must register as an employer within 15 days. Employers must also report newly hired or rehired California workers to the New Employee Registry within 20 calendar days of the employee’s first day at work. These are separate employer steps.
State tax and licensed work
Corporations and LLCs may have Franchise Tax Board filing and payment duties. FTB says every LLC doing business or organized in California must pay an annual tax of $800, and every corporation incorporated, registered, or doing business in California must pay the $800 minimum franchise tax unless an exception applies. Confirm your entity’s exact duties with the Franchise Tax Board business pages or a tax professional.
Some work needs a state license before you operate or advertise. Use DCA License Search for many licensed professions. Construction work may involve the Contractors State License Board. You can also use CalGold to look up possible permits by city and business type.
Federal checks
Many small businesses need an EIN. The IRS says you can get an EIN directly from the IRS for free, and it warns that you never have to pay a fee for an EIN. Use the IRS EIN page.
Costs you can plan for
San José’s business tax is only one possible cost. Other permit, health, state, or professional costs may apply.
| Cost | What to know | Where to confirm |
|---|---|---|
| San José Business Tax Certificate | Many standard businesses are taxed by employee count. The city rate page effective July 1, 2026 lists $222.89 for one to two employees, plus increments for higher counts. | City business tax rates page |
| SB-1186 state fee | The city rate page says businesses that do not qualify for an exemption must pay a $4 state fee each year. | City business tax rates page |
| County FBN filing | Needed only when your name situation triggers FBN rules. Fees and publication steps can change. | Santa Clara County Clerk-Recorder |
| Food or health permit | Restaurants, food trucks, catering, cottage food, temporary events, and other food activity may need county review. | Santa Clara County Department of Environmental Health |
| Building, planning, fire, sign, or vending permits | Costs depend on the work, use, site, sign, event, hazardous materials, and permit type. | San José Development Services, Planning, Fire, and related city pages |
| California entity and tax costs | LLCs, corporations, and other entities may have filing fees, annual taxes, and returns. | Secretary of State and Franchise Tax Board |
Real-world examples
Home-based web designer
A web designer working from a San José apartment may still need a Business Tax Certificate. They should check home business rules before seeing clients at home, storing business items, adding signs, or using workers. For a wider home business overview, see Can I run a business from home?
Small retail shop
A retail shop should check zoning before signing a lease, register for the city certificate, get a seller’s permit if selling taxable goods, check signs, and ask if tenant improvements need permits.
Food truck or cart
A food truck or cart may need the city certificate, a Santa Clara County Mobile Food Facility permit, California seller’s permit steps, and a city vending permit or Planning approval depending on where and how it operates. A temporary-event booth follows the county Temporary Food Facility route instead. For a broader overview, see our food truck license guide.
Contractor working in San José
A contractor may need the city certificate, a state contractor license if the work requires it, building permits for certain jobs, and records showing who pulled each permit. Contractors should confirm both city and CSLB rules before advertising or taking jobs.
Common mistakes to avoid
- Calling the San José Business Tax Certificate a full business license and assuming it approves the whole business.
- Signing a lease before checking zoning and use rules.
- Forgetting that out-of-town businesses doing business in San José may still owe city business tax.
- Counting only W-2 employees when the city’s employee definition may be broader.
- Opening a food business before checking Santa Clara County Environmental Health.
- Ordering signs before checking the San José Sign Code.
- Failing to close or update a city business tax account after moving, closing, changing locations, or changing business details.
- Paying a private website for an EIN when the IRS says EINs are free directly from the IRS.
