A study commissioned by the American Petroleum Institute, the national trade association for the U.S. oil and natural gas industry, concludes that a windfall profits tax on oil companies would cause the loss of about 490,000 jobs and reduce the nation’s gross domestic product by about 1 percent by 2030.

The legislation congress proposed would impose a tax of 50 percent on the windfall profits of integrated oil companies, producers of crude oil and refiners of crude oil with gross receipts of more than $1 billion.

The study finds that the tax would cause a drop in domestic oil production of up to 26 percent between 2010 and 2030, making the nation more dependent on imports.
