Effective April 1, 2017, the sales tax rate for the city of San Jose will increase from 8.75% to 9.25% due to a new local district tax of .5% for the county of Santa Clara. The .5% increase was approved by voters with the passage of Measure B on Santa Clara County ballots to provide more than $6 billion for road and transit improvements.  The sales tax rate for the city of Campbell will also be 9.25% whereas the rest of the county will be an even 9%.
