Are gas prices planning on increasing overnight in the beginning of year 2015? The answer for some states is yes. Particularly, California will be increasing as a tax, which will be an immediate jump overnight. So, keep on the look out if your state is doing it too, chances are, only the high volume states would incorporate this since gas is already a default need. Adjusting the prices too drastically is interesting given that state residents pay so much in Franchise Tax Board taxes, you would wonder, why is there so much tax charge on top of the taxes paid?
