Businesses selling into San Jose must charge the correct combined sales tax rate and know when California nexus rules apply. San Jose’s combined sales and use tax rate is 10.000%, effective April 1, 2026, per the California Department of Tax and Fee Administration (CDTFA) rate lookup. That rate applies citywide within Santa Clara County.
Charging the wrong rate creates liability you pay out of pocket. This guide gives you the verified 2026 rate, the nexus thresholds, and the register-collect-file steps.
What Is the San Jose Sales Tax Rate in 2026?
San Jose’s combined sales and use tax rate is 10.000%, effective April 1, 2026, according to the CDTFA. It rose from 9.375% after Santa Clara County voters approved a new countywide district tax. The rate applies to taxable sales delivered anywhere inside the city limits, which sit within Santa Clara County.
| Component | Rate | Source |
|---|---|---|
| California state rate | 6.00% | CDTFA |
| Bradley-Burns uniform local rate (1.00% city/county operations + 0.25% county transportation) | 1.25% | CDTFA |
| Statewide base subtotal | 7.25% | CDTFA |
| Voter-approved district taxes (Santa Clara County + San Jose) | 2.75% | CDTFA |
| Combined San Jose rate (effective April 1, 2026) | 10.000% | CDTFA |
Rates change when voters approve new districts. Confirm the current figure on the CDTFA rate lookup before you set up collection.
How Does California District Tax Work in San Jose?
Everything above California’s 7.25% statewide base is voter-approved district tax. San Jose’s premium is a stack of Santa Clara County and city district taxes totaling 2.75%. Individual district taxes generally run 0.10% to 2.00% each and can overlap, per the CDTFA, which is why urban California cities land roughly between 9.25% and 10.75%.
San Jose’s current premium comes from two recent voter measures on top of the county baseline.
| District measure | Rate | Status | Source |
|---|---|---|---|
| Santa Clara County Measure A | 0.625% | Approved Nov. 4, 2025 (57% yes); effective April 1, 2026; expires March 31, 2031 | Ballotpedia) |
| San Jose Measure B | 0.25% | Approved June 2016; sunsets Sept. 30, 2031 | Ballotpedia) |
| Unincorporated Santa Clara County combined rate | 9.750% | Effective April 1, 2026 | CDTFA |
Do I Need a Seller’s Permit in San Jose?
Yes. Anyone selling taxable tangible personal property in California needs a CDTFA seller’s permit. Registration is free and typically completed online through the CDTFA portal, and many applicants receive the permit immediately, per the CDTFA. Out-of-state sellers with economic nexus register for a Certificate of Registration – Use Tax instead.
To register, have your Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Federal Employer Identification Number (FEIN) ready, plus your entity details and projected sales. Commenda’s guide to the California sales tax permit walks through the full registration flow.
What Triggers Sales Tax Nexus in California?
Two things trigger California sales tax nexus: physical presence, or $500,000 in sales delivered into California. Either one obligates you to register with the CDTFA and collect tax. Nexus is the connection between your business and the state that creates a collection duty.
What counts as physical nexus?
Physical nexus comes from a real in-state footprint. That includes an office, store, or warehouse, inventory stored in the state, employees or agents operating in California, and owned or leased property. Inventory held in third-party fulfillment centers counts, so Fulfillment by Amazon (FBA) stock in a California warehouse creates nexus even for a remote seller.
How does California’s $500,000 economic nexus threshold work?
You have economic nexus once your combined sales of tangible personal property delivered into California exceed $500,000 in the current or preceding calendar year, per Assembly Bill 147 (AB 147), effective April 1, 2019, per the CDTFA. California uses no separate transaction-count test, unlike states with a “$100,000 or 200 transactions” rule.
The $500,000 is measured statewide, not city by city. Once you cross it, you are a retailer engaged in business in every district, so you collect the full combined rate at the delivery destination. Commenda’s US economic nexus threshold guide tracks this figure for every state.
What Is the Difference Between Sales Tax and Sellers Use Tax in California?
Sales tax is imposed on the retailer for in-state sales of tangible personal property. Use tax applies to the use, storage, or consumption of that property when sales tax was not collected, at the same combined rate. The buyer or an out-of-state seller owes it.
Out-of-state retailers with California nexus but no in-state physical presence collect seller’s use tax and report it under a different CDTFA category. The rate matches the sales tax rate, but the reporting line differs, and district collection obligations can vary depending on where the goods are delivered.
What Is Taxable in San Jose, and What Is Exempt?
California taxes tangible personal property by default, while most services and groceries are exempt. Physical goods carry the full 10.000% combined San Jose rate. Unprepared food, prescription drugs, and professional services do not.
Is software taxable in San Jose, California?
Prewritten software sold on tangible media, such as a disk or USB drive, is taxable in California. Software delivered electronically, custom software written for one client, and cloud-hosted Software-as-a-Service (SaaS) are generally not taxable, per CDTFA guidance. California is more software-friendly than many states, so most downloaded and hosted products fall outside the tax.
How Do Online Sellers Handle San Jose Sales Tax?
Remote sellers over the $500,000 threshold must collect the full 10.000% combined San Jose rate on taxable orders delivered into the city. Marketplaces collect for their third-party sellers under California’s Marketplace Facilitator Act, effective October 1, 2019, which makes platforms like Amazon, Etsy, and eBay responsible for collecting and remitting tax on facilitated sales.
Direct sales through your own site remain your responsibility once you have nexus. Because AB 147 extended district-tax collection statewide, you charge tax based on where the package is delivered, not where you ship from.
How Do You Collect Sales Tax in San Jose?
Apply the full 10.000% combined rate at the point of sale, or at the delivery destination for shipments into the city. Keep your rates current, because district taxes change when voters approve new measures. Sourcing is destination-based, so an order shipped to a San Jose address takes the San Jose rate.
Verify the rate for each address before you collect. Commenda’s sales tax calculator looks up current US rates instantly. It handles rate lookups only and does not check your nexus exposure.
How Do You File Sales Tax Returns in San Jose?
File with the CDTFA online, on the frequency the CDTFA assigns you. Returns are due the last day of the month after the reporting period. You must file even in periods with no taxable sales.
Late and unremitted tax carries real penalties.
File through the CDTFA e-file system to stay on schedule.
What Is the San Jose Business Tax?
San Jose levies a separate city business tax on companies with an office or employees in the city. The City of San José administers it, not the CDTFA, so it is distinct from your state sales tax obligation. The base tax starts at $216.35 for businesses with 1 to 2 employees, per the City of San José, and the rates adjust annually.
Landlords and property businesses pay rates based on square footage or units. This tax is a registration and licensing charge on operating in the city, not a tax on sales.
