City of San Jose Business License Requirements

To operate legally in San José, you need a Business Tax Certificate, which is the city’s version of a business license. Registration is required within 90 days of starting any commercial activity inside city limits, and the base tax for a business with one or two workers is $219.60 as of July 2025.¹ The San Jose business license requirements apply whether you run a storefront, work from home, or are based outside the city but perform paid work inside it.²

Who Has to Register

If you earn money from activity conducted inside San José city limits, you need a Business Tax Certificate. That covers brick-and-mortar shops, home-based operations, independent contractors, and companies physically located elsewhere that perform work in the city.³ San José Municipal Code Chapter 4.76 defines “doing business” broadly enough to sweep in essentially any commercial activity for financial gain, with no requirement that you keep a fixed office or storefront in town.

The city’s definition of an employee is also wider than most people assume. For tax purposes, it includes owners, family members helping out, partners, agents, managers, and anyone else working for a wage, salary, commission, or even room and board.¹ A spouse answering the phones and a teenager packing orders both count when calculating your tax.

What It Costs

San José calculates the business tax primarily by employee headcount. These rates took effect July 1, 2025, and are adjusted annually for inflation (capped at 1.5% on the base tax and 3% on incremental rates).¹

1–2 employees (base tax): $219.60
3–35 employees: $37.06 per additional employee
36–100 employees: $49.40 per additional employee
101–500 employees: $61.75 per additional employee
501+ employees: $74.15 per additional employee
Annual cap: $185,532.59

Every business also owes a $4 annual state fee under California SB-1186, which funds disability access compliance programs. A few business categories have their tax calculated differently under the Municipal Code, but the employee-based formula covers most registrants.

Exemptions

Several categories of registrants owe no tax. Senior citizens, nonprofit organizations, and veterans are among the exempt groups listed in Municipal Code Section 4.76.6.⁴ Even if you qualify, you still have to register and claim the exemption; no one is automatically excused.

Two other programs are worth knowing about. A financial hardship exemption is available if your business’s gross receipts are at or below twice the federal poverty level ($31,300 for the 2025 tax year) and your adjusted gross household income is at or below four times the poverty level ($62,600). Separately, businesses that newly locate within the Downtown Business Improvement District on leases or owner-user purchases made between January 1, 2025, and December 31, 2026, may qualify for a tax exemption.

How to Register

Registration happens online at businesstax.sanjoseca.gov.² Have this ready before you start:

Legal business name and ownership structure (sole proprietorship, LLC, corporation, partnership, etc.)
Tax identification number: a Federal Employer Identification Number, Social Security Number, or Individual Taxpayer Identification Number
Start date of business activity in San José
Estimated annual gross receipts if you are a new business
NAICS code (the North American Industry Classification System code for your type of business)

If you pay during registration, your account activates within two to three business days. If you skip payment, an invoice arrives by mail within five to ten business days. After you pay, the city mails the official certificate. There is no multi-week review period.

Running a Business From Home

Home-based businesses in San José do not need a separate planning permit, but they still need the Business Tax Certificate and have to follow specific rules meant to keep residential neighborhoods residential.⁵

Client visits: no more than two clients in your home at one time, and only between 9 a.m. and 9 p.m.
Employees: only people who live in the dwelling can work for the home business.
Vehicles: one business vehicle under 10,000 pounds manufacturer’s gross weight can be kept on the property.
Space: operations can take place in the dwelling or an attached garage (without displacing required parking). A detached garage or accessory building can devote only 100 square feet to the business. Carports and yards are off-limits.
Nuisances: no odors, vibrations, glare, fumes, dust, electrical interference, or noise detectable outside the home.
Manufacturing: only handcrafted products are allowed.

Breaking any of these can draw code enforcement attention. The trade-off for skipping a planning permit is staying inside those lines.

Displaying, Renewing, and Closing the Certificate

The city requires you to display the certificate at your place of business at all times.³ For a home-based business, that usually means your workspace. For retail, near the entrance or register.

The tax renews annually on the 15th of the month your business originally started. Opened March 3? The tax is due every March 15 going forward.⁶ You can pay online through the city’s e-billing system or by mail. The city may send a renewal reminder as a courtesy, but it isn’t legally required to. Municipal Code Section 4.76.281 says notification is not a prerequisite for the tax being due. If no notice arrives, you still owe. Put it on your own calendar.

If your business moves out of the city, changes address, or closes, notify the Finance Department using the online closure form. Skipping this step is a common and expensive oversight. The city will keep billing the annual tax and penalties will accrue on each missed payment, even if you stopped operating months ago. Nothing cancels automatically.

Penalties for Paying Late

Late payments compound quickly:

Unpaid by the due date: 25% penalty added to the tax owed
Still unpaid one month later: another 25% penalty on top of the first
Ongoing interest: 1.5% per month on all unpaid tax and penalties

New businesses get one break. If this is the first time your business tax is due and you pay in full within 90 days of the due date, the city waives all penalties and interest. The grace period applies only once.

Federal Obligations That Come With Starting a Business

A San José Business Tax Certificate handles your local obligation. Opening a business also triggers federal requirements that catch first-time owners off guard.

Employer Identification Number

Any business with employees, any partnership or corporation, and anyone filing employment tax returns needs a Federal Employer Identification Number from the IRS.⁷ Sole proprietors without employees can technically use their Social Security Number, but most get an EIN anyway to keep their SSN off W-9 forms and invoices. The application is free and takes minutes online.

Worker Classification

When you hire help, the IRS expects you to classify each worker correctly as either an employee or an independent contractor. The distinction turns on how much control you have over the work: whether you direct what gets done, how it gets done, and the financial terms of the arrangement.⁸ Misclassifying employees as contractors is one of the most common and expensive mistakes small businesses make, and it can trigger back taxes, penalties, and interest at both federal and state levels.

Record Retention

The IRS generally requires you to keep business tax records for at least three years after filing, matching the standard audit window. Underreport income by more than 25% and that window extends to six years. Most accountants recommend seven years as a safe baseline. Payroll tax records should be kept for four years after the due date.
