No industry enjoys the array of tax breaks and subsidies that the oil and gas industry does. No industry needs them less. For all the damage it has caused, the disastrous oil spill in the Gulf of Mexico may provide the political momentum to end this special treatment.

President Obama’s 2011 budget, proposed before the spill, would eliminate $4 billion in annual tax breaks for oil and gas companies. Bills in both houses introduced after the spill would achieve many of the same results. Industry has spent $340 million on lobbying over the last two years to block these sorts of initiatives, and until recently Congress has been eager to do its bidding. This year could be different.

The White House has proposed eliminating nine tax breaks. Some are modest, all are complicated, but in toto they provide a range of cushy benefits  fast write-offs for upfront drilling expenses, generous depletion allowances, and the like  that are available at virtually every stage of the exploration and production process.

The net result, as The Times reported recently, is an effective tax rate on investment far lower than that paid by other industries. That, the Treasury Department argues, has encouraged overinvestment in oil and gas drilling at the expense of other parts of the economy.
