Effective July 1, 2011, the California sales and use tax rate will decrease by 1%. The temporary 1% increase implemented in April 2009 expires June 30, 2011. (California SBE Tax Information Bulletin 388, June 1, 2011)
Remember that district taxes are still applicable, so the tax rates vary. For a list of rates as of April 1, 2011, go to http://www.boe.ca.gov/cgi-bin/rates.cgi.
The proposed budget plan does include additional sales tax for online retailers like Amazon.com, but there are currently no proposals to extend the additional 1% sales tax beyond June 30.
