California Sales Tax Calculator
California sales tax starts with a 7.25% statewide base rate, but the actual combined rate can be higher because of local district taxes. This page helps you estimate tax on a purchase, compare city-level examples, and understand when you should confirm the rate with the CDTFA address lookup tool.
Why California Sales Tax Is Hard to Estimate
California’s base state rate is 7.25%, but many locations add local rates, pushing the combined total above 9% and sometimes above 10%.
- State rate: 7.25% (applies statewide)
- County & city add-ons: vary by location
- Special districts: transit and other local projects
Tip: Use the city calculators for the exact combined rate. This state hub is best for learning and quick estimates.

Common California Sales Tax Questions
These are the issues shoppers and sellers run into most often:
- Grocery vs. Prepared Food: Most cold food products and groceries are tax-exempt, but "hot prepared food" or meals consumed on-site typically trigger the full combined rate.
- Digital goods and software: Tax treatment depends on what is being sold and how it is delivered. If the transaction is significant, review CDTFA guidance rather than relying on a general rule of thumb.
- Shipping Charges: Shipping costs are often non-taxable if they are separately stated on the invoice and the shipment is made directly to the purchaser via a common carrier.

How to Look Up California Sales Tax by ZIP Code or Address
