First off, over the past 25 years, oil companies directly paid or remitted more than $2.2 trillion in taxes, after adjusting for inflation, to federal and state governments—including excise taxes, royalty payments and state and federal corporate income taxes. That amounts to more than three times what they earned in profits during the same period, according to the latest numbers from the Bureau of Economic Analysis and U.S. Department of Energy. Oh and that does not include local property taxes, state sales and severance taxes and on-shore royalty payments.
Secondly, according to the Congressional Research Service (CRS), the 1980s windfall profits tax depressed the domestic production and extraction industry and furthered our dependence on foreign sources of oil.
Thirdly, someone has already mentioned who gets the lion's share of 'profits'. The government has actually “profited” more from the oil industry than the industry has earned for its shareholders.
