Californians pay the highest gas taxes in the nation, and the taxes are so complex that even the State Board of Equalization (the agency that collects the taxes), can't explain how gas taxes are calculated. To complicate matters further, retailers are  taxed on some of the taxes they pay (a tax on a tax), and in 2010, the State of California, implemented a slippery "swap tax"in 2010 in order to siphon funds dedicated to highway repair into the State General Fund.
