I was reviewing my tax return for the last year this morning. I have 17 diesel trucks of varying sizes. We drove 512000 miles last year and consumed just over 34000 gallons of Highway diesel fuel. Now the federal tax rate on diesel fuel is 24.4 cents a gallon, state is .$.34. Some areas have local, but that is a lot harder too figure out so we don't go there. So in just my fuel usage, the federal is 8296, state is 11560, for a total of $19856. Just in fuel taxes! I dropped $20k in f....k taxes on diesel. I also had another 7k gallons of off hwy use fuel, but that is taxed differently.
Now here is the gross part, average price at the pump was ~$2.64. So roughly 22% was tax. Think about that, next time you are at the pump, ~25% is tax.
Ps I really wish I had not seen that.
