Congress debates windfall taxes on oil profits as industry records record cash gains

Wood Mackenzie forecasts that the oil and gas industry will capture roughly $495 billion in excess profits for 2026, a level not anticipated before the U.S.-Israel conflict with Iran. President Donald Trump has publicly claimed the companies are “making too much money.” In response, Congress is considering three distinct tax initiatives: a bipartisan bill proposing a 50% excise tax per barrel on the difference between current Brent prices and a 2025 baseline of $69; a separate measure that would levy a 100% tax on the portion of prices exceeding $75 per barrel; and a proposal to raise the excise tax on stock buybacks from 1% to 25% for large oil firms.

The American Petroleum Institute warns such taxes could erode investment certainty, yet Wood Mackenzie notes that the largest firms are set to retain about $272 billion of the windfall, roughly matching their annual investment budgets, while buybacks are expected to decline and dividends remain steady. Historical experience from the 1980s windfall tax suggests revenue projections may be overstated. The debate centers on balancing revenue generation, fairness, and the limited impact on actual capital spending.
