How much do I charge for Sales Tax if I'm doing business with all of California?

It's not just county rates. There are some cities within a county that charge higher rates. The sales tax rate for the state will be decreasing as of July 1st because the "temporary" increase expires, unless the voters are stupid and vote for another increase like Brown wants.

There is a state rate that you can charge and then residents will have to declare the difference on their state tax returns. BOE has all that info. They don't like this anymore than we do but that's the law.

Sales & Use Tax

http://www.boe.ca.gov/info/taxoverview.htm

Retailers engaged in business in California must register with the BOE and pay the state's sales tax, which applies to all retail sales of goods and merchandise except those sales specifically exempted by law. The use tax generally applies to the storage, use, or other consumption in California of goods purchased from retailers in transactions not subject to the sales tax. Use tax may also apply to purchases shipped to a California consumer from another state, including purchases made by mail order, telephone, or Internet.

The sales and use tax rate in a specific California location has three parts: the state tax rate, the local tax rate, and any district tax rate that may be in effect.

State sales and use taxes provide revenue to the state's General Fund, to cities and counties through specific state fund allocations, and to other local jurisdictions.

You charge by the sales tax in your area.

State base rate + any county rate in your area + any city rate in your area.

Calif sales tax is 8.75 and when you file the sales tax return you have to keep track of the sales to those communities that have 9.25%, this is reported on your tax return--look at the tax return and see how the district taxes are alloted

If they come to you to pick up what you sell, you charge by the rate for where you are. If you ship to them, you charge by the rate for where they are.
