How to navigate the next phase of federal energy tax policy

As federal energy tax rules evolve, companies must weigh near-term constraints against longer-term investment decisions.


In brief
  • US energy policy under the One Big Beautiful Bill Act has been recalibrated to focus on energy security, domestic manufacturing and supply chain resilience.
  • Firms face tighter timelines, stricter sourcing rules and a policy environment that links energy tax incentives with trade and national security priorities.
  • Companies can benefit by positioning investments around reliable, scalable energy sources and long-term carbon management solutions while still being nimble.

To understand today’s energy tax landscape, it is essential to examine the legislative shift from the Inflation Reduction Act (IRA) to the One Big Beautiful Bill Act (OBBBA). The IRA reflected a climate-first approach, establishing long-term investment tax credits intended to last well into the 2030s or until emissions targets were met. The main purpose of these incentives was to encourage decarbonization by promoting the use of renewable energy.

The OBBBA marks a meaningful change in emphasis by reorienting federal energy tax policy toward energy independence, energy security and domestic manufacturing. Accelerated cost recovery measures, including 100% bonus depreciation and the permanent extension of full R&D expensing, significantly benefit US manufacturers. At the same time, tighter foreign-entity-of-concern rules, which restrict projects with prohibited foreign ownership, influence or supply chain involvement, are intended to pull supply chains back toward North America.

 

This shift reflects an energy strategy that prioritizes reliability and availability over narrow technology preferences. Under the OBBBA, energy security is treated as an economic and national security objective, reshaping how tax incentives are deployed across the energy value chain.

Changes and near-term challenges for businesses

The rebalancing of energy tax incentives has altered which sectors stand to benefit most. Under the OBBBA, the “winning” sectors extend beyond renewable generation to include domestic manufacturing and traditional energy infrastructure, including oil, gas, metals and mining. These industries benefit both from favorable cost recovery rules and from policies aimed at reducing permitting obstacles and bringing energy projects to market more efficiently.

Within the energy space, several credits were preserved or enhanced. The IRC Section 45Q carbon oxide sequestration credit remains a central feature, supporting carbon capture projects across energy and industrial operations, including those tied to enhanced oil or natural gas recovery. The IRC Section 45Z credit for producing low-emission transportation fuel has been expanded in certain contexts, and recent regulatory developments have provided additional clarity that has helped stimulate investment. Advanced manufacturing credits under IRC Section 45X now include certain critical mineral activities, including metallurgical coal. Zero-emission nuclear credits and incentives for deep drilling and utility-scale geothermal energy were also largely retained.

Despite these opportunities, businesses face real challenges. Accelerated phaseouts compress project timelines, sourcing rules complicate procurement and supply chain planning, and policy uncertainty increases the risk of misaligned capital investments. Companies that previously relied on long-dated, technology-neutral credits must now reassess assumptions about project economics and eligibility under a more targeted incentive regime.

What comes next

Looking ahead, the next phase of federal energy tax policy is likely to be shaped by rapidly growing energy demand and the need to meet that demand with a diverse mix of energy sources. Longer-term policy may focus on enabling reliable, predictable and affordable energy while integrating cleaner technologies where feasible.

A notable trend is the potential shift from how energy is produced to how carbon is managed. Credits such as IRC Section 45Q are expected to become enduring features of the tax code, offering a bridge for existing energy and manufacturing infrastructure as decarbonization goals evolve. At the same time, energy tax policy is increasingly intertwined with trade policy, as sourcing rules and supply chain considerations play a central role in eligibility and planning.

For companies, the message is clear. Organizations should continue to monitor legislative and regulatory developments closely, model multiple pricing and supply chain scenarios and stress-test investment decisions against policy volatility. Businesses with longer-term horizons should reassess capital allocation strategies now to stay aligned with an energy tax framework focused on security and domestic production. At the same time, those strategies need enough flexibility to respond to short-term disruptions driven by geopolitical events or other developments.

Summary

Federal energy tax policy is shifting as incentives move away from broad decarbonization goals toward energy security and domestic production. While opportunities remain across manufacturing, traditional energy and select low-carbon technologies, businesses now face tighter timelines, more complex sourcing rules and greater policy uncertainty. Companies should reassess investment assumptions and stay flexible as the policy landscape continues to evolve.
