With the tax filing deadline fast approaching, our pals at Stewart's want to remind us how much in taxes we pay out everytime we hit the gas pumps. And if you happen to be smoker, then you are realy getting taxed up the wahzoo, so much so, that ya might want to consider kicking the habit and investing what you'd be saving into Philip Morris stock!. The Stewart's example is based on $4 a gallon gas - of which the government takes 67 cents. That's $6.70 in taxes for every ten gallons that goes into your tank.
