Business License in San Jose (2026): Business Tax Certificate Costs, Deadlines and Home Businesses

Whether you're opening a nail salon in Evergreen, running a software consultancy from a Willow Glen bedroom or renting out a duplex in Berryessa, San Jose expects you to register your business and pay its business tax every year. Most people search for a "San Jose business license", but the City calls it a Business Tax Certificate. This guide explains who needs one, what it costs under the rates in force from July 1, 2026, how employees are counted, the deadlines and penalties, the 2026 amnesty program, hardship exemptions and the home occupation rules. Every figure was checked against City of San José Finance Department pages in October 2026.

Quick answer

Anyone doing business in San Jose, including home-based, part-time and self-employed people and landlords, must register for a Business Tax Certificate with the City's Finance Department within 90 days of starting. From July 1, 2026, the annual tax is $222.89 for 1–2 employees, plus $37.98 per employee from the 3rd to the 35th, plus the $4 state fee.

• The owner counts as an employee, so a solo business pays the base tax

• Due every year on the 15th of the month you started; no grace period

• Late: 25% penalty, another 25% a month later, plus 1.5% a month interest

• Amnesty waives penalties and interest until December 31, 2026

• San Jose sales tax rate: 10%

Who needs a San Jose Business Tax Certificate

The City's rule is that every person or company conducting business in San Jose must register for a Business Tax Certificate. It's a tax, not a permission: once you register and pay, the certificate you receive is the official receipt for your payment. You'll hear it called a business license or business permit, and for practical purposes it's the same thing.

The City lists the types of business that usually pay, and the list is broad: commercial and residential landlords, stores, wholesalers, manufacturers, service companies, self-employed workers, independent contractors and home-based businesses. It applies to part-time businesses too. A rideshare driver, a weekend wedding photographer and a retired engineer doing occasional consulting are all in business for this purpose.

Being based elsewhere doesn't exempt you if you do business in San Jose. A contractor from Santa Clara or Milpitas working on San Jose jobs is conducting business in the city. Keep the certificate posted at your place of business. And remember what it doesn't do: the City says the certificate isn't approval for zoning, fire rules, occupancy or any other permit you need from the City, Santa Clara County, the State or federal agencies.

San Jose business tax rates in 2026

For most businesses, the tax is based on the number of employees. The City adjusts the rates every July 1 for inflation, using the Bay Area consumer price index, with increases capped at 1.5% a year for the base tax and 3% a year for the per-employee brackets and the cap.

The incremental rates are per employee, and they stack: a 50-person business pays the base for its first two people, the 3–35 rate for the next 33 and the 36–100 rate for the remaining 15.

Who counts as an employee

This is the detail that catches most people. The City's definition of an employee includes every person engaged in running the business, whether as owner, a member of the owner's family, partner, associate, agent, manager or solicitor, as well as everyone working for a wage, salary, commission or room and board. So a husband-and-wife bakery with one hired baker has three employees, not one. You report your count when you register and can update it through the City's online employee count form.

Rates for landlords

Property owners are taxed on what they rent rather than on staff. Residential landlords pay the same base tax for 1–2 units, then $12.65 per unit from the 3rd to the 35th from July 1, 2026, with higher per-unit rates for larger portfolios. Commercial landlords pay the base tax plus $0.0316 per sq ft of rented space. Mobile home park owners pay per rented lot. A homeowner renting a back-house ADU is a residential landlord with one unit and pays the base tax.

On top of all of these, California's SB 1186 adds a $4 fee to every local business license or renewal for businesses that aren't exempt. It funds disability access education and compliance.

How to register and pay

You register online through the City's business tax registration form, by mail with the paper registration form, or in person by appointment at City Hall, 200 East Santa Clara Street. Have these ready:

• your business start date in San Jose;
• a tax identification number (FEIN, SSN or TIN) and the principal owner's driver's license number;
• owner names and addresses, phone and a valid email;
• the address of each San Jose location where you do business;
• your contractor's license number, state seller's permit number or County health permit number, if you have them.

If you pay during online registration, your account activates in 2 to 3 business days. If you don't, an invoice arrives by mail within 5 to 10 business days. At City Hall, the application is processed while you wait, and paying the full amount gets you a temporary certificate on the spot with the official one mailed later.

You can pay online by ACH or eCheck with no fee, or by card with a 2.66% service fee charged by the City's processor. Cash and checks are accepted in person, and checks by mail. A failed payment carries a $26 returned payment fee.

5. 5

   Diary the annual due date

   The tax is due every year on the 15th of the month you started. Renewal notices are a courtesy; penalties apply without one.

Deadlines, penalties and the 2026 amnesty

You must register within 90 days of starting business in San Jose. After that, the tax is due every year on the 15th of the month your business started: a business that opened in March 2026 renews by March 15 each year. The online payment page updates about three weeks before your renewal date. Use the City's Business Tax Lookup to find your account number and due date.

The penalties are steep and start the day after the due date, with no grace period:

• a 25% penalty if the tax isn't paid by the due date;
• a further 25% penalty if it's still unpaid one calendar month later; and
• interest of 1.5% a month on the unpaid tax and penalties.

There's a softer rule for brand-new businesses. Since July 1, 2017, if a new business pays its first business tax in full within 90 days of the due date, the City waives all penalties and interest up to the payment date. This only applies the first time the tax is due.

The Business Tax Amnesty Program

From January 1 to December 31, 2026, San Jose is running a Business Tax Amnesty Program. It's for businesses that never registered, haven't paid on time, or underreported employees, building size or rental units. You pay the tax you owe and the City waives the penalties and interest. If you've been operating without a certificate, perhaps freelancing or renting a room for years, this is the cheapest moment to fix it. Register through the normal online form and call the business tax line at 408-535-7055, option 2, with questions.

Exemptions and the Financial Hardship Program

The Municipal Code, chapter 4.76, exempts some people and organizations from business tax, including certain senior citizens, nonprofit organizations and veterans. You must apply using the City's online exemption request form; exemption isn't automatic, and you may need to renew it.

The Financial Hardship Program exempts very small businesses on low incomes. The thresholds track federal poverty guidelines: for tax year 2026, business gross receipts up to $31,920 (twice the poverty level) and adjusted household income up to $63,840 (four times the poverty level). If your side business brings in $20,000 and your household income is modest, it's worth applying.

There's also a time-limited Downtown BID special exemption. Businesses new to downtown that locate inside the Downtown Business Improvement District through a lease or owner-user purchase made between January 1, 2025 and December 31, 2026 may be exempt from business tax. You apply through a separate online form, and the Office of Economic Development and Cultural Affairs has the details.

Home businesses and home occupations

Working from home doesn't exempt you from the business tax. The City explicitly includes home-based businesses, and you register like anyone else. What working from home adds is a set of zoning rules for home occupations. According to the City's Planning Division, a home occupation must stay incidental to the home and meet performance criteria, including:

• clients may visit only between 9 a.m. and 9 p.m.;
• no more than one business vehicle under 10,000 pounds gross weight may be kept on the property;
• the business can use the dwelling and an attached garage, as long as required covered parking stays usable; in a detached garage only 100 square feet may be used, and nothing may be stored in carports or yards;
• manufacturing is limited to hand-crafted products, and direct retail display is limited to 15 square feet, though you can fill orders placed online, by phone or by mail;
• no odors, noise, vibration, glare or dust detectable outside the home, and signs must meet residential sign rules.

Some activities can't be run from a home at all. The City's list includes appliance repair (other than small household appliances), firearms sales, motorized garden tool repair, massage businesses, pest control, upholstery, food catering outside the state Cottage Food rules, most vehicle-related uses, welding, anything needing a Fire Department hazardous materials permit and off-sale alcohol. Ask Planning at 408-535-3555 if your idea is borderline.

Worked examples

These use the rates from July 1, 2026, and include the $4 state fee.

A solo bookkeeper working from home in Willow Glen. She is her business's only employee, so she pays the base tax of $222.89 plus the $4 fee: $226.89 a year. If her gross receipts were under $31,920 and her household income under $63,840, she could apply for the hardship exemption instead.

A nail salon in Evergreen with the owner and five technicians. That's six employees. The base covers the first two; the other four pay $37.98 each, $151.92. With the base and state fee, the total is $378.81. Technicians working as independent contractors in the salon may need their own certificates, because each is in business in San Jose.

A landlord with a fourplex in Berryessa. The base covers two units, and the other two pay $12.65 each: $222.89 + $25.30 + $4 = $252.19.

A software company downtown with 50 employees. The base covers two; 33 employees at $37.98 add $1,253.34; and 15 at $50.62 add $759.30. Total: $2,235.53, plus $4. It collects no sales tax on most software services, but if it sells taxable hardware, it charges 10%.

Other registrations, sales tax and Measure E

The Business Tax Certificate is only the City's tax registration. Depending on your business you may also need:

• a seller's permit from the California Department of Tax and Fee Administration if you sell taxable goods. It's free. The combined sales tax rate in San Jose is 10% in 2026, which includes Santa Clara County's 0.625% Measure A district tax, operative since April 1, 2026. Our California sales tax guide covers what's taxable and how to file;
• a fictitious business name filing with the Santa Clara County Clerk-Recorder if you trade under a name other than your own;
• a County Department of Environmental Health permit for restaurants, food trucks and other food businesses;
• City regulatory permits for certain activities, listed on the Finance Department's regulatory permit forms page; and
• a state license for regulated trades such as contracting, cosmetology or real estate.

Measure E comes up in many San Jose searches, and it's not a business license tax. San Jose voters approved it in March 2020 as a real property transfer tax on high-value property sales, with tiered rates that rise for larger transactions. It matters only if your business buys or sells expensive real estate; check the City's current Measure E thresholds before a transaction.

Common mistakes

Not counting yourself. The owner is an employee under the City's definition. A business with "one employee plus me" is a two-employee business.

Waiting for a renewal notice. The tax is due on the 15th of your start month whether or not a notice arrives, and the first 25% penalty applies the next day.

Assuming part-time or side work is exempt. The City names part-time businesses and independent contractors. Apply for the hardship exemption if your income is low, rather than not registering.

Forgetting rentals. Renting out a single room long-term or an ADU makes you a residential landlord for business tax purposes.

Missing the amnesty window. If you've been operating unregistered, paying through the amnesty by December 31, 2026 avoids penalties that can otherwise exceed 50% of the tax plus interest.

Not updating your counts. Report changes in employees, units or square footage, and close your account when you stop, so you aren't billed for a business you no longer run.

Frequently asked questions

How much is a business license in San Jose?

San Jose's business license is called a Business Tax Certificate, and the tax depends on your number of employees. From July 1, 2026, it's $222.89 a year for 1 to 2 employees, plus $37.98 for each employee from the 3rd to the 35th, with higher per-employee rates above that. Every non-exempt business also pays the $4 state disability access fee.

Do I need a San Jose business license to work from home?

Yes. The City says self-employed workers, independent contractors, home-based and part-time businesses all need a Business Tax Certificate. Your home business must also meet the zoning code's home occupation rules, such as limits on client hours, vehicles, signs and retail display space. Some activities, like welding, pest control and vehicle repair, aren't allowed as home occupations.

When is the San Jose business tax due?

You must register within 90 days of starting business in San Jose. After that, the tax is due every year on the 15th of the month your business started. The City expects payment by that date even if you don't get a renewal notice, and penalties start the day after with no grace period.

What is the penalty for paying San Jose business tax late?

A 25% penalty is added if the tax isn't paid by the due date, and another 25% if it's still unpaid a calendar month later. Interest of 1.5% a month is charged on unpaid tax and penalties. During 2026, the Business Tax Amnesty Program waives penalties and interest for unregistered or underpaid businesses that pay the tax by December 31, 2026.

Is Measure E a San Jose business tax?

No. Measure E, approved by San Jose voters in March 2020, is a real property transfer tax charged when high-value property is sold. It doesn't affect the annual Business Tax Certificate. Most small businesses will only meet Measure E if they buy or sell expensive commercial property, and the City publishes its current thresholds and rates.

Can I get an exemption from San Jose business tax?

Possibly. Seniors, nonprofits, veterans and some other groups can apply for exemptions under Municipal Code chapter 4.76. The Financial Hardship Program exempts small businesses with low income: for tax year 2026, the limits are business gross receipts of $31,920 and adjusted household income of $63,840. You apply with the City's online exemption form.
