What the Rate Applies To
California taxes retail sales of tangible personal property, meaning physical items you can carry out of a store: furniture, clothing, electronics, tools, and the like.5Taxes.

Digital Goods and Downloads
California treats digital products differently from many other states. Software downloads, eBooks, mobile apps, digital images, and similar products delivered purely over the internet, without any physical storage medium, are generally not subject to sales tax.9California Department of Tax and Fee Administration. Internet Sales Publication 109 – Nontaxable Sales The moment a seller bundles a physical backup (a flash drive, a printed manual, a disc), the whole sale becomes taxable. Streaming subscriptions are untaxed; the same software bought on a disc at a retail store is not.
Vehicle Purchases
Vehicles work on slightly different mechanics. A California dealer collects sales tax at the point of sale. If you buy from a private party or an out-of-state seller, you owe use tax instead, typically paid when you register with the DMV.10California Department of Tax and Fee Administration. Tax Guide for Purchasers of Vehicles The rate is tied to where you register the vehicle, so a 95129 resident registering at their home address pays the local combined rate. The tax applies to the full purchase price, including the fair market value of any trade-in or property exchanged.
Online and Out-of-State Purchases
If you buy something from a retailer that doesn’t collect California sales tax and then use, store, or consume the item in California, you owe use tax at the same rate as the local sales tax, which for a 95129 address is 9.375%.11California Department of Tax and Fee Administration. California Use Tax, Good for You. Good for California Most large online retailers already collect it under marketplace facilitator rules, but purchases from small out-of-state vendors, private sellers, or foreign websites can arrive without tax charged.
For individuals without a seller’s permit, the simplest way to report use tax is on your California state income tax return. The return instructions include a worksheet, and the Franchise Tax Board publishes a lookup table based on income if you’d rather not track individual purchases. You can also pay use tax directly through the CDTFA’s online services.
A Quick Note on Verifying the Rate
The 9.375% figure reflects the current combined rate published by the CDTFA for 95129. Because district taxes come and go with local ballot measures, the rate can change. For routine shopping the published rate is reliable; for a vehicle registration, a large appliance, a construction order, or anything where a tenth of a percent matters, confirming by exact address through the CDTFA lookup is the safe move.
