California District Tax Examples 2026

Why California rates vary

California sales tax starts with the statewide base rate, then local district taxes can stack on top. District taxes may fund transportation, county services, or local measures. Because the district boundary can be narrower than a county, two addresses in the same region can have different combined rates.

This is why Los Angeles, San Francisco, San Diego, Oakland, Long Beach, and nearby cities do not all use the same number. The safest workflow is to use the exact delivery address or the CDTFA lookup before quoting a final invoice.

District taxes are voter-approved and can change when new measures pass or existing ones expire. A rate that was accurate last year may no longer apply. Sellers and tax software providers should generally update their rate tables at least quarterly to stay current.

Common city rate examples for 2026

As of mid-2026, some commonly referenced combined rates include: Los Angeles at approximately 10.25%, San Francisco at approximately 8.625%, San Jose at approximately 9.375%, and San Diego at approximately 7.75%. These rates may vary by exact address within each city, so always verify before invoicing.

Dollar comparison on a $500 purchase: Los Angeles (10.25%) adds roughly $51.25 in tax for a $551.25 total. San Francisco (8.625%) adds roughly $43.13 for a $543.13 total. San Jose (9.375%) adds roughly $46.88 for a $546.88 total. San Diego (7.75%) adds roughly $38.75 for a $538.75 total.

The spread between the highest and lowest example rates here is $12.50 on a $500 purchase. For a $2,500 appliance, that same spread becomes roughly $62.50—a meaningful difference for both shoppers comparing stores and sellers quoting prices.

For a $10,000 commercial order, the tax in a 10.25% location would be approximately $1,025, while the same order at 7.75% would produce approximately $775 in tax—a $250 difference that can affect project budgets and purchasing decisions.

Compliance notes

California sales tax can be destination-based for district tax purposes. Ecommerce sellers should pay close attention to the buyer address and whether their tax software is using the latest local district table.

If you are a shopper comparing nearby stores, ask for the final checkout total rather than assuming the state base rate tells the whole story.

Sellers should also be aware that some California district taxes apply only to certain transaction types or have specific sourcing rules. When in doubt, the CDTFA website or a California tax professional can help clarify which district taxes apply to your specific business.

Using the CDTFA rate lookup tool

The California Department of Tax and Fee Administration (CDTFA) provides a free online tax rate lookup tool at cdtfa.ca.gov. Sellers and shoppers can enter a street address to get the current combined rate, including all applicable district taxes. This is generally the most reliable way to confirm a rate before invoicing.

When using the CDTFA tool, enter the full delivery address rather than just a city name or ZIP code. Some cities have multiple rate areas, and a ZIP code may span different districts. The tool typically returns the combined state, county, city, and district rate for the specific location.

For ecommerce sellers processing many California orders, most tax automation platforms (such as Avalara, TaxJar, or Shopify Tax) pull from similar address-level databases. However, it is often wise to spot-check a few addresses against the CDTFA tool periodically to confirm your software is returning accurate rates.
