How much is the total sales tax for IPhone5S in california, San Jose. I bought it for 199$ in AT&T website. I seen salestax in Best buy for 150$ is 69$.Is the same for AT&T too?

San Jose's tax is 8.75%. In California, you have to pay sales tax on the unsubsidized price (ie, price without contract) of the iphone. The unsubsidized price is $649.00 for the 16GB version so the tax should be $56.79.
