Please link to the program that subsidizes oil.
Please do NOT imply that the oil companies do not have tax subsidies. Let's remember that the government has a LARGE stake in maintaining a large and profitable fossil fuel business. They make 10 times more off of oil profits than the oil companies themselves make.
Section 199 of the US Tax Code gives a 6% tax subsidy to “qualified production activities”. This includes fossil fuel companies and excludes renewable energy companies.
The foreign tax credit allowances appear to be designed specifically for oil companies. While some people claim that they are being abused by the oil companies as I pointed out, the government makes more off of oil company profits than the oil companies themselves so so they are unlikely to change it.
There is also the oil depletion allowance which allows oil companies to depreciate the oil reserves. This isn't to pretend that oil itself depreciates but that each year this oil isn't pumped out the more expensive it is to pump it out and process it into fuel.
So the oil companies DO have loopholes and subsidies but it ALL promotes more income to the US government as well as their own stockholders.
