Yes — California sales tax applies to online purchases delivered to a California address, and the rate is the same whether the seller sits in San Diego or ships from another state. The statewide base is 7.25%, and local district taxes push the combined rate higher in most areas, with some cities above 10%. Large platforms collect the tax automatically at checkout. When a seller doesn’t collect it, you owe the same amount directly to the state as use tax.
When the Seller Charges Tax at Checkout
Most of the time, you’ll see California tax added to your order before you pay. Two rules explain why.
The first is economic nexus. Under Revenue and Taxation Code Section 6203, an out-of-state retailer must register with the California Department of Tax and Fee Administration (CDTFA) and collect tax once its combined sales of tangible personal property delivered into California exceed $500,000 in the current or preceding calendar year.1California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6203 The $500,000 figure covers all sales into California, including nontaxable ones, and there’s no separate transaction-count requirement.2California Department of Tax and Fee Administration. Use Tax Collection Requirements Based on Sales into California Due to the Wayfair Decision California’s threshold is higher than the $100,000 figure most other states use, so a smaller online retailer might collect tax on orders shipped elsewhere but not on yours.
The second is the marketplace facilitator rule. Under Assembly Bill 147, which took effect in 2019, a platform that connects buyers and sellers and also handles at least one operational function such as payment processing, order fulfillment, or listing is treated as the retailer for tax purposes.3California Legislative Information. California Assembly Bill 147 – Use Taxes: Collection: Retailer Engaged in Business in This State: Marketplace Facilitators The platform must collect, report, and pay tax on every retail sale of tangible goods it facilitates into California, and the individual third-party seller is relieved of collection duty for those sales.4California Department of Tax and Fee Administration. Tax Guide for Marketplace Facilitator Act If you’re buying on a major online marketplace, the tax at checkout is generally correct.
How Much Tax You Actually Pay
The 7.25% statewide base is a floor. Cities and counties layer on voter-approved district taxes, and multiple districts can overlap in one location, stacking on top of each other. Individual district rates run from 0.10% to 2.00%.5California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rate Information Combined rates in some cities exceed 10%. The CDTFA maintains an address lookup tool that returns the exact rate for any California address.6California Department of Tax and Fee Administration. Know Your Sales and Use Tax Rate
For online orders, the rate that applies is based on where the goods are delivered, not where the seller sits. Two California residents ordering the same item from the same site can pay different tax amounts based on their zip codes.
What’s Taxable and What Isn’t
California taxes sales of “tangible personal property,” which the Revenue and Taxation Code defines as anything that can be seen, weighed, measured, felt, or touched.7California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6016 Clothing, electronics, furniture, appliances, and most other physical goods you order online fall inside that definition.
Digital Products
Products delivered purely by electronic transfer are generally not taxable. Streamed movies, downloaded music, ebooks, and software transmitted directly to your device sit outside the tangible personal property definition, and the same treatment applies to SaaS subscriptions and online database access.8California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 120.0000 The line shifts when a physical medium is involved: software on a USB drive or a game on a disc is taxable. Bundling a digital product with a physical item in one transaction can make the entire bundle taxable.
Groceries and Prescriptions
Most food bought for home consumption is exempt, covering produce, dairy, meat, bread, cereal, canned goods, and non-carbonated bottled water. The exemption does not reach prepared food sold hot, carbonated beverages, or alcohol.9California Department of Tax and Fee Administration. Sales and Use Tax Regulations – Article 8 Prescription medicine ordered through an online pharmacy is exempt under Revenue and Taxation Code Section 6369. Over-the-counter supplements and non-prescription drugs generally are not.
Shipping Charges
Whether tax applies to shipping depends on how the charge is written. Actual shipping costs a seller passes through to you are generally not taxable if separately stated on the invoice. Handling charges are taxable. If shipping and handling are combined into a single line item, the whole charge can become taxable, and if the seller doesn’t keep records of actual delivery costs, tax applies to the full delivery charge on a taxable sale.10California Department of Tax and Fee Administration. Shipping and Delivery Charges (Publication 100)
Paying Use Tax When Nobody Collected It
When an online seller doesn’t charge California tax, you owe the same amount as use tax.11California Department of Tax and Fee Administration. California Use Tax This comes up most with smaller out-of-state retailers under the $500,000 threshold, foreign websites, and private-party sales.
You have two ways to pay:
- On your California income tax return. The state forms include a line for use tax. If you don’t have receipts for every purchase, the CDTFA publishes a Use Tax Lookup Table that estimates your liability from adjusted gross income; for most income levels under $200,000, the table amount is modest, from a few dollars up to around $17. Large untaxed purchases should be reported at their actual tax amount rather than the table estimate.12California Department of Tax and Fee Administration. California Use Tax Table
- Directly through the CDTFA’s website. Businesses with a seller’s permit report use tax on their regular sales and use tax return.11California Department of Tax and Fee Administration. California Use Tax
Penalties for Not Paying
If the CDTFA determines you owe unpaid use tax, the standard penalty is 10% of the unpaid amount. A separate 10% penalty applies if you were required to file a return and didn’t. Interest runs from the date the tax was originally due, calculated at the federal underpayment rate plus three percentage points.13California Department of Tax and Fee Administration. Regulation 1703 In cases involving fraud or intentional evasion, the penalty jumps to 25% of the tax owed, on top of the filing penalty. Those harsher penalties require clear and convincing evidence of intent, so they’re reserved for serious cases, but the underlying obligation applies to every taxable purchase whether the seller collects at checkout or not.
