California adds an additional layer with special district taxes, which are applied at the county level. The foundational state sales tax rate is set at 6%, with a standard county rate of 0.25%. Local city rates can vary from 0% to 2%, while special district taxes range between 1% and 3.25%. For the most current official rates and information, always refer to the California state government's dedicated website.

California's Combined Sales Tax Rate

The combined sales tax rate is the total of all applicable state and local rates. In 2022, the average combined rate across California was approximately 8.61%. This figure serves as a general guideline, but the actual rate for any specific transaction depends entirely on the exact location of the purchase or delivery.
