Federal Fossil Fuel Tax Benefits Total $19.1 Billion

Why It Matters

A recent Congressional Research Service report puts a number on federal fossil fuel tax benefits, and the figure is both smaller than critics might expect and larger than supporters would prefer.

The report, authored by CRS analysts Nicholas E. Buffie and Donald J. Marples and published April 29, arrives as Congress is deep in budget reconciliation talks and the Trump administration is pushing an aggressive energy dominance agenda. The findings don't resolve the political debate over oil and gas tax incentives, but they sharpen it, giving both sides new ammunition.

The Big Picture

The CRS report catalogs the major federal fossil fuel tax benefits flowing to oil, natural gas, and coal producers through the U.S. tax code. Using estimates from the Joint Committee on Taxation, the report finds the largest of these benefits total approximately $19.1 billion over fiscal years 2025 through 2029, an average of $3.8 billion per year.

The two biggest provisions are longstanding features of the tax code. The first is percentage depletion, which allows independent oil and gas producers and royalty owners to deduct 15 percent of gross income from a property, rather than deducting the actual cost of capital as it depletes. The second is intangible drilling costs, which lets companies immediately expense most costs associated with drilling a well rather than capitalizing and depreciating them over time. Both provisions have been on the books for decades.

The report also covers interactions with passive loss rules and the alternative minimum tax, where fossil fuel companies receive special treatment, as well as credits for enhanced oil recovery and carbon capture - provisions the report notes are designed to reduce emissions, not simply to subsidize production.

One methodological note matters for how these numbers get used politically: the JCT and the Treasury Department produce different estimates of the cost of these energy tax deductions, owing to differences in baseline assumptions, treatment of passive loss rules, and projections for economic growth. The report flags this dispute directly. For one provision covering multiple energy sources and estimated at $4.4 billion, CRS removed approximately $1.2 billion attributable to non-fossil fuel sources, leaving $3.2 billion specifically tied to fossil fuels.

Political Stakes

For the Trump administration, the relatively modest scale of these petroleum tax breaks relative to the overall budget offers a ready-made defense. The CRS report notes that the $3.8 billion annual average equals just 0.07 percent of federal spending and 0.05 percent of revenues over the same period. That framing allows the administration to argue that preserving these federal fossil fuel subsidies carries minimal fiscal consequence while supporting domestic energy production - a central pillar of its energy dominance agenda.

The administration also has an incentive to lean on Treasury's lower estimates rather than JCT's when defending these provisions in budget negotiations, a choice the report implicitly makes possible by documenting the disagreement between the two agencies.

For Republicans in Congress, the picture is more complicated. Reconciliation talks are centered on finding offsets for tax cuts, and while $3.8 billion a year is small relative to the overall federal budget, it is not nothing. The report's documentation of these oil and gas tax incentives could surface in negotiations if deficit hawks push for a broader review of tax expenditures. That said, the energy industry's political standing within the Republican coalition makes these provisions among the least likely targets.

For Democrats, the report offers a contrast that has become central to their energy and climate argument. The Inflation Reduction Act, which dramatically expanded clean energy tax credits, has been significantly curtailed under the current Congress. Meanwhile, fossil fuel tax credits dating back decades remain untouched. The CRS accounting makes that asymmetry concrete and quantifiable.

For the public, the report is a reminder that energy policy is also tax policy, and that choices embedded in the tax code (some of them decades old) shape the economics of domestic energy production in ways that rarely surface in the annual budget debate.

The Bottom Line

The CRS report is a nonpartisan fiscal accounting, not a policy recommendation. But its timing gives it political weight.

Congress is negotiating a budget that will require tradeoffs. The administration is defending an energy agenda built on expanding fossil fuel output. And the international community, through G7 forums and other bodies, has repeatedly called on the United States to phase out what it characterizes as inefficient fossil fuel subsidies. This report quantifies what that conversation is actually about.

The core takeaway is straightforward: federal fossil fuel tax benefits are real, measurable, and durable. At roughly $3.8 billion per year, they are not a dominant line item in a multi-trillion-dollar federal budget. But they represent a deliberate policy choice (one that Congress has renewed, implicitly or explicitly, for decades) and one that now sits in sharper relief against a backdrop of rolling back clean energy incentives.
