The Big Oil Windfall Profits Tax Act would establish a per-barrel tax for large oil companies, and returning the revenue generated to the American people as a quarterly rebate. The tax itself would be equal to half of the difference between the price of a barrel of oil this year and last year. At a $100-per-barrel price, that’s $33 billion raised annually. This would return at least $200 to filers under a certain income threshold each year—which is approximately how much the war has cost everyday Americans so far.
