Sacramento, CA, December 11, 2012 – The statewide sales and use tax rate is about to go up. The tax will increase one quarter of one percent (0.25%) from 7.25 percent to 7.50 percent on January 1, 2013. Across California, the sales and use tax rate will range from 7.50 percent to 10.00 percent because in some cities and counties, voter-approved district taxes are added to the statewide base rate. The rate increase was approved by California voters when they approved Proposition 30 on November 6, 2012. Proposition 30 increases the statewide sales and use tax rate for four years. Starting January 1, everyone will pay more for taxable purchases made in local stores or by Internet and mail order. The sales and use tax rate increase does not apply to purchases of gasoline. However, the sales and use tax rate increase does apply to purchases of diesel fuel.
