San Diego's Current Sales Tax Rate

San Diego County's sales tax rate is 7.75 percent as of 2024. This rate applies to most retail purchases within the county's unincorporated areas and most incorporated cities. The rate is made up of the California state sales tax (7.25 percent) plus a local San Diego County tax (0.5 percent).

Some cities within San Diego County add their own local tax on top of this base rate. For example, the City of San Diego itself charges an additional 1.25 percent, bringing the total to 8.25 percent for purchases made within city limits. Other cities like Chula Vista, Oceanside, and Escondido have their own local rates that vary. If you are shopping near a city border, the tax you pay depends on where the register is located, not where you live.

What Items Are Subject to Sales Tax in San Diego

Sales tax in San Diego applies to tangible goods—items you can touch and take home. Clothing, electronics, furniture, toys, and household items are all taxed. Restaurant meals and prepared foods are taxed, though unprepared groceries from a supermarket are not. Alcohol and tobacco products are taxed at the standard rate, though tobacco also carries a state excise tax on top.

Services are generally not subject to sales tax in California, even in San Diego. If you pay a plumber, electrician, accountant, or hairdresser, that service charge is not taxed. However, if you buy a product as part of that service—say, a new faucet installed by a plumber—the product itself may be taxed depending on how the invoice is written.

What Is Exempt From Sales Tax

Groceries and food intended for home consumption are not taxed in California. This includes bread, milk, vegetables, meat, and canned goods. The rule is straightforward: if it is raw food you cook at home, it is not taxed. Hot prepared foods from a deli counter or restaurant are taxed because they are considered ready to eat.

Prescription medications are also exempt from sales tax in San Diego. You will not pay tax when you fill a prescription at a pharmacy. Over-the-counter medications like pain relievers and cold medicine are taxed as regular goods. Medical devices prescribed by a doctor—such as diabetic testing supplies or hearing aids—may be exempt, but the rules are specific and depend on the device.

How Sales Tax Works on Online and Out-of-State Purchases

If you order something online from a retailer with a physical location in California, San Diego sales tax applies to your order based on your delivery address. Large online retailers like Amazon, Walmart, and Target collect and send sales tax to California. Smaller online sellers may not, and you technically owe the tax yourself, though enforcement is rare for individual purchases.

If you order from a seller with no California presence, sales tax may not be collected at checkout. California law requires you to report this tax on your state income tax return as "use tax," but most individuals do not. The practical effect is that out-of-state purchases often avoid the tax entirely.

Sales Tax on Cars and Large Purchases

When you buy a car in San Diego, sales tax applies to the purchase price. The rate depends on where the dealership is located. If you buy from a dealer in the City of San Diego, you pay 8.25 percent tax. If you buy from a dealer in an unincorporated area, you pay 7.75 percent. You cannot avoid this by registering the car elsewhere—California taxes the sale itself, not the registration.

Trade-ins reduce the taxable amount. If you buy a car for $20,000 and trade in a vehicle worth $5,000, you pay tax only on the $15,000 difference. This applies to any large purchase where a trade-in is involved, though it is most common with vehicles.

Why Sales Tax Rates Differ Across San Diego County

San Diego County's sales tax is not uniform because different cities have voted to add their own local taxes for specific purposes. The City of San Diego's extra 1.25 percent, for example, was approved by voters to fund transportation and other services. Chula Vista, Oceanside, and other cities have their own local measures that voters approved at different times.

These local taxes are not arbitrary—they appear on the ballot, voters decide whether to approve them, and the revenue goes to specific city services. When you cross from one city into another, the tax rate changes because you are now in a different jurisdiction with different voter-approved taxes.

Frequently Asked Questions

Is sales tax the same everywhere in San Diego County?

No. The base rate is 7.75 percent in unincorporated areas, but cities add their own local taxes. The City of San Diego charges 8.25 percent. Chula Vista, Oceanside, Escondido, and other cities have different rates. Check your receipt or the city's tax assessor website to confirm the rate where you are shopping.

Do I pay sales tax on groceries?

No, not on unprepared groceries. Raw food you take home and cook is not taxed. Hot prepared foods from a deli, bakery, or restaurant counter are taxed because they are ready to eat. If you are unsure, ask the cashier before checkout.

What about sales tax on used items?

Used items sold by a business are taxed the same way as new items. If you buy a used car from a dealership, you pay sales tax. If you buy a used item from an individual at a garage sale or through a private sale, no sales tax applies because there is no business involved.

Do I owe sales tax on things I order online from out of state?

If the seller has no California location, sales tax may not be collected. Technically you owe "use tax" to California, but enforcement for individual purchases is minimal. Large retailers with California operations do collect and send the tax.

Can I get a sales tax refund if I move out of California?

No. Sales tax is final at the point of purchase. If you buy something in San Diego and then move, you do not get a refund. Some states offer refunds on large purchases like cars if you move within a certain time, but California does not.
