Starting in 2010, the Fuel Tax Swap provides for a combination of lowering the sales and use tax rate applicable to sales of motor vehicle fuel and simultaneously raising the state excise motor vehicle fuel tax. Starting in 2011, the same law raises the sales tax rate applicable to diesel and simultaneously lowers the excise tax on diesel. For more information go to the state Board of Equalization website, www.boe.ca.gov, and search for fuel taxes.
