The Cupertino sales tax rate is 9.125%. That total applies to most retail purchases of tangible goods inside city limits, from a laptop to a dining table to a new car. It combines California’s 7.25% statewide base with 1.875% in district taxes that Santa Clara County voters have approved over the years.1California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rates
District taxes can shift when new ballot measures pass or old ones expire, so the 9.125% figure is current rather than permanent. The CDTFA keeps a rate lookup tool on its website where you can enter any California address and confirm the current rate.
What Makes Up the 9.125%
California’s 7.25% statewide base is the same everywhere in the state. It splits into several pieces: 3.9375% goes to the State General Fund, 0.50% supports local public safety and criminal justice, 0.50% funds local health and social services under a 1991 realignment, and 1.0625% feeds the Local Revenue Fund set up in 2011. The remaining 1.25% is the local Bradley-Burns share. Of that, 1% flows directly to the city where the sale takes place, and 0.25% goes to the county transportation fund.2California Department of Tax and Fee Administration. Detailed Description of the Sales and Use Tax Rate
The 1% Bradley-Burns money is what gives Cupertino unrestricted general fund revenue from local retail sales. The city can spend it on police, fire, parks, library hours, street repairs, or whatever else the budget needs.2California Department of Tax and Fee Administration. Detailed Description of the Sales and Use Tax Rate
The 1.875% stacked on top comes from Santa Clara County voter measures passed over several decades. Those include transportation taxes administered by the Santa Clara Valley Transportation Authority, the 2016 Measure B transportation improvement tax, a hospital and healthcare services tax, and a levy supporting the Santa Clara Valley Open Space Authority.1California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rates Each measure is locked to the specific purpose voters approved, so that money can’t be redirected the way the Bradley-Burns share can.
What the 9.125% Applies To
The rate attaches to retail sales of tangible personal property, which California defines as anything you can see, weigh, measure, feel, or touch.3California Department of Tax and Fee Administration. Revenue and Taxation Code 6016 – Tangible Personal Property That covers electronics, clothing, furniture, appliances, office supplies, and vehicles. Leases of tangible property are generally taxed the same way as outright purchases.4California Department of Tax and Fee Administration. Sales and Use Tax in California
What Is Not Taxed
Groceries bought for home consumption are exempt. Raw ingredients, packaged snacks, canned goods, and cold drinks from a grocery store do not carry sales tax. The exemption disappears once the food is sold heated, served as a meal, or eaten on the seller’s premises.5California Department of Tax and Fee Administration. Tax Guide for Grocery Stores
Hot prepared food is taxable even when you take it home. A burrito from a taqueria, a rotisserie chicken from a deli counter, and a hot coffee drink all carry the 9.125%.6California Department of Tax and Fee Administration. Common Sales and Use Tax Nontaxable Sales and Partial Exemptions
Prescription medicine is exempt when prescribed by a licensed physician, dentist, or podiatrist and dispensed by a pharmacist. The same exemption applies to permanently implanted medical devices, prosthetics, orthotics, and artificial limbs.7Cornell Law Institute. California Code of Regulations Title 18 Section 1591 – Medicines and Medical Devices Over-the-counter products like aspirin and cough syrup remain taxable.
Pure services aren’t taxed. Repair labor, legal advice, accounting work, and similar professional services carry no sales tax when no physical product changes hands. Fabrication labor is the exception: if someone is building a new product for you, the labor is taxable.6California Department of Tax and Fee Administration. Common Sales and Use Tax Nontaxable Sales and Partial Exemptions
The lines can get fine. A cold sandwich from the grocery store is exempt; press it in a panini maker before selling it and the same sandwich becomes taxable. When classification isn’t obvious, the CDTFA publishes industry-specific guides to help sellers get it right.
Online and Out-of-State Purchases
When you buy something from an out-of-state seller that doesn’t charge California sales tax, you owe use tax at the same 9.125% rate. Use tax exists to keep people from avoiding sales tax by ordering across state lines. The rule of thumb is simple: if the item would be taxed when bought in Cupertino, it’s taxed when you bring it in from elsewhere.8California Department of Tax and Fee Administration. California Use Tax
For most people, the easiest way to pay is on your California income tax return, which includes a use tax line and a lookup table so you can estimate based on income rather than tracking every purchase. You can also pay directly through the CDTFA’s online services.8California Department of Tax and Fee Administration. California Use Tax
In practice this comes up less often than it used to. California requires marketplace facilitators like Amazon, eBay, and Etsy to collect and remit sales tax for their third-party sellers once the platform exceeds $500,000 in California sales, so most online checkouts already include the right rate. Use tax now mainly matters when you order directly from a small out-of-state business, buy through a private sale, or bring goods in from another state.
If You Sell Goods in Cupertino
Any business selling or leasing tangible goods in California needs a seller’s permit from the CDTFA before making its first sale. The permit is free and the application is online.9California Department of Tax and Fee Administration. Obtaining a Seller’s Permit Selling without one is a misdemeanor under state law.10California Department of Tax and Fee Administration. Revenue and Taxation Code 6071
Once registered, you collect the 9.125% at the point of sale and hold it in trust for the state. The CDTFA assigns a filing frequency based on your sales volume: yearly for very small sellers, monthly for high-volume ones, with quarterly the most common.11California Department of Tax and Fee Administration. Filing Dates for Sales and Use Tax Returns Missing a filing deadline triggers a 10% penalty on the unpaid tax, plus interest from the original due date.12California Department of Tax and Fee Administration. Revenue and Taxation Code 6591 Sales and purchase records need to be kept for at least four years unless the CDTFA authorizes shorter retention in writing.13California Department of Tax and Fee Administration.
