Big Oil Windfall Profits Tax Act This bill imposes an excise tax on the windfall profits of crude oil on taxpayers who extracted and imported more than 300,000 barrels (a barrel equals 42 U.S. gallons) of taxable crude oil (i.e., crude oil, crude oil condensates, and natural gasoline) in 2019, or who extracted and imported that amount in the current calendar quarter. The bill requires rebates of the tax collected to be paid to individual taxpayers. The bill establishes the Protect Consumers from Gas Hikes Fund to finance such rebates.
