In the U.S., there are three levels (jurisdictions) on which sales tax are applied:

• State;
• County; and
• City/municipality.

In some states, California included, there is also a so-called special rate (a special district tax applied on a county level).

The state sales tax in California is 6%, and the county rate is 0.25%. City/municipality rates vary between 0% and 2%, and the special rates vary between 1% and 3.25%.

Yes. California sales tax is 6% state sales tax plus 0.25% county sales tax plus municipality and special taxes that range between 0% and 2% and 0%-3.25%, respectively. As of October 2022, the average combined sales tax rate is 8.82%.

To determine the sales tax in California, you need to:

1. Know the purchase amount (add shipping cost, if any).

2. Determine the state sales tax rate and the county sales tax rate that apply in your case.

3. Multiply the purchase amount by the sum of applicable rates.
