The One Big Beautiful Bill Act brought major shifts to U.S. green energy incentives. Many credits now phase out earlier. Some programs face new limits tied to foreign entities. Others keep their original purpose but follow new rules for timing or component sourcing.
If you work in energy, manufacturing, real estate, or large-scale development, you will feel these changes. The bill touches everything from solar and wind projects to clean hydrogen, commercial buildings, and clean vehicles.
Below is a clear look at what changed and how it affects future planning.
Faster sunsets for clean electricity credits
The Production Tax Credit (45Y) and Investment Tax Credit (48E) move toward early phaseout. Solar and wind projects follow strict new timelines and face tougher rules tied to foreign entities.
Tighter deadlines for solar and wind
To receive remaining credits, projects must begin construction by July 4, 2026. They must be placed in service by December 31, 2027. These dates leave little margin for delays or supply chain problems.
Expanded support for carbon capture
The carbon sequestration credit (45Q) now covers more project types. This includes facilities using captured carbon for enhanced oil recovery and other approved uses. The credit amount is higher, which strengthens the value of qualified projects.
New limits tied to foreign entities
The act sets new rules for Foreign Entities of Concern. A project becomes ineligible if it receives material help from a restricted foreign entity. These limits apply at both the project and company level.
New sourcing rules for key components
Solar modules, battery components, and critical minerals follow new domestic content rules starting in 2026. Thresholds rise over time. Companies with overseas suppliers will need to adjust fast.
Changes to energy-efficient building incentives
The deduction under section 179D remains available. Projects must begin construction by June 30, 2026 to qualify. The Energy-Efficient Homes credit (45L) ends for homes acquired after the same date.
Loss of accelerated depreciation for energy property
Five-year MACRS depreciation no longer applies to solar, wind, and similar property if construction begins after December 31, 2024. This shifts long-term cost planning for developers that rely on shorter depreciation schedules.
End dates for hydrogen and other clean energy credits
The clean hydrogen credit (45V) ends for projects that begin construction after 2027. Several other credits face early termination between late 2025 and mid-2026. These include:
• Clean vehicles (30D)
• Commercial clean vehicles (45W)
• Charging stations (30C)
• Residential clean energy systems (25D)
What this means for developers and taxpayers
These changes shorten timelines and introduce more conditions across the incentive landscape. Projects in planning must review schedules and sourcing strategies now. Companies exposed to foreign entity restrictions face higher compliance risk. Some opportunities remain, but the window is smaller.
