President Trump signed the “One, Big, Beautiful Bill Act” (the “OBBB”) into law on July 4, 2025. Congress passed the legislation using the budget reconciliation process to avoid the 60-vote Senate filibuster. In addition to making many of the individual tax cuts from the 2017 Tax Cuts and Jobs Act permanent, the bill makes significant changes to many of the clean energy credits included in the Inflation Reduction Act of 2022 (the “IRA”).
Projects that began construction before 2025 and are planning on claiming production tax credits (“PTCs”) or investment tax credits (“ITCs”) under sections 45 and 48 are generally unaffected by the OBBB. However, the OBBB is a mixed bag when it comes to the other energy tax credits that were introduced or extended by the IRA. The OBBB makes substantial cuts to the tech-neutral tax credits for solar and wind and eliminates certain other energy tax credits (e.g., those for hydrogen, EVs and homeowners), but other technologies and activities (e.g., geothermal, carbon capture, nuclear, clean fuel production) experienced fewer claw backs of the benefits provided by the IRA. The OBBB also adds foreign entity of concern (“FEOC”) restrictions to the surviving energy tax credits. Finally, the OBBB expands the definition of “qualifying income” (“QI”) for master limited partnerships (“MLPs”) under section 7704(d)(1)(E).
While a prior version of the OBBB released by the Senate contained an excise tax on certain wind and solar facilities deemed to have received material assistance from a prohibited foreign entity (“PFE”), the tax was removed shortly before its passage by the Senate and is not included in the OBBB.
On July 7, 2025, President Trump also issued an Executive Order (Ending Market Distorting Subsidies for Unreliable, Foreign Controlled Energy Sources) (the “EO”) directing the Secretary of the Treasury to, within 45 days of enactment of the OBBB, “take all action as the Secretary of the Treasury deems necessary and appropriate to strictly enforce the termination of the clean electricity production and investment tax credits under sections 45Y and 48E of the Internal Revenue Code for wind and solar facilities.” The EO specifically directs Treasury to issue new and revised guidance on “beginning of construction” (BOC), and notes that broad safe harbors should not apply “unless a substantial portion of a subject facility has been built.” In the same 45-day window, Treasury is also directed to implement the FEOC restrictions in the OBBB.
Below is a summary of the key changes for the clean energy industry as a result of the enactment of the OBBB.
I. TAX CREDIT AND DEDUCTION MODIFICATIONS
1. Sections 45Y (Clean Electricity Production Tax Credit) and 48E (Clean Electricity Investment Tax Credit)
- FEOC: Disallows the credits when certain FEOC provisions are triggered. These provisions are discussed below in Section II.
- PIS DEADLINE: Adds a placed in service (PIS) deadline for solar and wind facilities of December 31, 2027.
- Applies to facilities that begin construction after July 4, 2026 (i.e., more than 12 months after the enactment of OBBB).
Akin Note: Allowing construction to begin for up to one year after enactment was a late change to OBBB. However, taxpayers’ ability to take advantage of this window may be limited as a result of guidance to be issued by Treasury implementing the EO.]
- Applies to facilities that begin construction after July 4, 2026 (i.e., more than 12 months after the enactment of OBBB).
-
- Statute makes clear that batteries are not impacted by this change. Other facilities that qualify for credits under §§ 45Y and 48E (besides solar and wind facilities) are also not impacted.
[Akin Note: The language making clear that batteries are not impacted by this change is arguably not necessary in light of the Treasury position in regulations that energy storage technologies cannot be part of qualified facilities.]
- Statute makes clear that batteries are not impacted by this change. Other facilities that qualify for credits under §§ 45Y and 48E (besides solar and wind facilities) are also not impacted.
- LEASING DISALLOWANCE: Disallows credits for solar electric heating and small wind residential property if the taxpayer rents or leases the property.
- Applies to taxable years beginning after July 4, 2025 (i.e., after enactment of the OBBB).
[Akin Note: In earlier versions of OBBB, this rule also applied to residential photovoltaic solar systems. The final enacted version of OBBB does not disallow ITCs or PTCs for residential photovoltaic solar systems.]
- Applies to taxable years beginning after July 4, 2025 (i.e., after enactment of the OBBB).
- PHASEOUT TIMELINE: Sets both §§ 45Y and 48E to begin phasing out in 2032.
- Except for solar and wind facilities that have a special PIS deadline (see above), facilities that qualify for either §§ 45Y or 48E and:
- BOC before 2034 can access the full credit;
- BOC in 2034 can access 75% of the credit;
- BOC 2035 can access 50% of the credit; and
- BOC after 2035 cannot access either credit.
- Except for solar and wind facilities that have a special PIS deadline (see above), facilities that qualify for either §§ 45Y or 48E and:
- TAX OWNERSHIP OF GEOTHERMAL HEAT PUMPS: For purposes of determining tax ownership geothermal heat pumps for depreciation and tax credit purposes, the fact that such property is not readily usable by anyone other than the lessee or offtaker is disregarded.
[Akin Note: This point removes a key obstacle to allowing geothermal heat pumps to be subject to “third party ownership” structures which more readily allows for tax equity financing.]
- FUEL CELL FACILITIES (§ 48E (ITC) only): Removes requirement that the anticipated greenhouse gas emission rate not be greater than zero for fuel cell facilities.
- Changes apply to facilities the construction of which begins after December 31, 2025.
- Sets a 30% ITC rate without the ability to increase with adders and apparently without needing to satisfy Prevailing Wage and Apprenticeship requirements.
- NUCLEAR ENERGY COMMUNITY (§ 45Y (PTC) only): Creates an energy community adder based on local employment in nuclear facilities, nuclear R&D, and nuclear component manufacturing.
- DOMESTIC CONTENT (§ 48E (ITC) only): Facilities that begin construction on and after June 16, 2025, are subject to the same domestic content thresholds for the ITC as the PTC.
- Domestic content thresholds are 45% for BOC in 2025, 50% for BOC in 2026 and 55% for BOC in 2027+ (separate rates still apply for off-shore wind).
[Akin Note: This change corrects what has long been viewed as a typo or glitch in the statutory framework.]
- Domestic content thresholds are 45% for BOC in 2025, 50% for BOC in 2026 and 55% for BOC in 2027+ (separate rates still apply for off-shore wind).
-
- Facilities that began construction before June 16, 2024, can utilize a 40% threshold.
2. Section 45Z (Clean Fuel Production Tax Credit)
- FEOC: Disallows the credit when certain FEOC provisions are triggered. These provisions are discussed below in Section II.
- CREDIT EXTENSION: Extends the deadline to sell eligible fuel from December 31, 2027, to December 31, 2029.
- EMISSIONS RATES: Disallows emissions rates from being negative, excludes indirect land use changes from the lifecycle analysis, and requires Treasury to provide emissions rates for each specific animal manure feedstock.
- Applies to transportation fuels produced after December 31, 2025.
[Akin Note: Many clean fuels producers were hoping to be able to generate multiples of the statutory credit rate as a result of their fuel having negative emissions rates. This change eliminates this possibility, which had previously been implied by other statutory language that contemplated negative emissions rates.]
- Applies to transportation fuels produced after December 31, 2025.
- FEEDSTOCK SOURCING: Requires feedstock to be produced or grown exclusively in the United Stated, Mexico or Canada.
- Applies to transportation fuels produced after December 31, 2025.
- Disallows any feedstock sources that already generated a 45Z credit but includes a directive to Treasury to issue regulations or guidance to implement this anti-double counting rule.
- RELATED PARTY SALES: Directs Treasury to expand the rule allowing sales between related parties prior to a sale to an unrelated party.
- SUSTAINABLE AVIATION FUEL: Eliminates the increased credit rate of $1.75/gallon for sustainable aviation fuel (SAF), but the standard $1.00/gallon rate remains available for SAF.
- Applies to transportation fuels produced after December 31, 2025.
- EXCISE TAX CREDIT: Eliminates the ability to claim § 45Z and the § 6426(k) excise tax credit for the same fuel.
- Applies to fuel sold or used on or after July 4, 2025 (i.e., enactment of the OBBB), and to fuel sold or used before such date if claims for the § 6426(k) excise tax credit have not been paid or allowed as of such date.
3. Section 45Q (Carbon Oxide Sequestration Tax Credit)
- FEOC: Disallows the credit when certain FEOC provisions are triggered. These provisions are discussed below in Section II.
- CREDIT RATES: Equalizes the credit rate for all potential disposal pathways (g., EOR, secure geologic storage and utilization) to $17/MT (indexed for inflation after 2026).
- Rate is $36/MT for direct air capture.
- Applies to facilities PIS after July 4, 2025 (i.e., after the date of the enactment of OBBB).
4. Section 45X (Advanced Manufacturing Production Tax Credit)
- FEOC: Disallows the credit when certain FEOC provisions are triggered. These provisions are discussed below in Section II.
- SALE OF INTEGRATED COMPONENTS: No credit for the sale of integrated components unless certain requirements are satisfied.
- Applies to taxable years beginning after December 31, 2026.
- To the extent an eligible component (called a “primary component”) is incorporated into another eligible component (called a “secondary component”) prior to sale to an unrelated person, a 45X credit is allowed with respect to the primary component only if:
- The secondary component is produced in the same manufacturing facility as the primary component; and
- At least 65% of the total direct material costs of the secondary component are attributable to primary components which are mined, produced or manufactured in the United States.
- PHASEOUT FOR WIND ENERGY COMPONENTS: Wind energy components, sold after December 31, 2027, no longer generate a 45X credit.
- PHASEOUT FOR CRITICAL MINERALS: Adds a phaseout for applicable critical minerals produced after 2030 based on timing of production.

- ADDITION OF METALLURGICAL COAL: Metallurgical coal added as an applicable critical mineral.
- Defined as “metallurgical coal which is suitable for use in the production of steel (within the meaning of the notice published by the Department of Energy entitled ‘Critical Material list; Addition of Metallurgical Coal Used for Steelmaking’ (90 Fed. Reg. 22711 (May 29, 2025))), regardless of whether such production occurs inside or outside of the United States.”
- Generates credit at a special rate of 2.5% of costs (as opposed to 10% for other critical minerals).
- Applies only to metallurgical coal produced before December 31, 2029.
- REVISED DEFINITION OF BATTERY MODULE: Definition of “battery module” is updated to include a requirement for the module to include “all other essential equipment needed for battery functionality, such as current collector assemblies and voltage sense harnesses, or any other essential energy collection equipment.”
- Applies to taxable years beginning after July 4, 2025 (i.e., taxable years beginning after the enactment of OBBB).
5. Section 45U (Zero-Emission Nuclear Power Production Credit)
- FEOC: Disallows the credit when certain FEOC provisions are triggered. These provisions are discussed below in Section II.
- CREDIT TERMINATION: Terminates credit for electricity produced and sold after December 31, 2032.
6. Terminated Credits and Deductions
- SECTION 45V (CLEAN HYDROGEN PRODUCTION TAX CREDIT): The deadline for beginning construction under §45V is moved up to December 31, 2027 (instead of December 31, 2032).
- EV RELATED CREDITS: Credits for EVs and EV charging property are eliminated.
- The deadlines for acquiring an eligible vehicle under §§ 25E (Previously Owned Clean Vehicle Credit), 30D (Clean Vehicle Credit), and 45W (Qualified Commercial Clean Vehicle Credit) are moved up to September 30, 2025 (instead of December 31, 2032).
- The deadline for PIS under § 30C (Alternative Fuel Vehicle Refueling Property) is moved up to June 30, 2026 (instead of December 31, 2032).
- RESIDENTIAL CREDITS: Credits energy efficient homes and residential clean energy tax credits are eliminated.
- The PIS deadline for residential clean energy property under § 25D (Residential Clean Energy Credit) of December 31, 2034, is replaced with a deadline for incurring expenditures of December 31, 2025.
- The deadline for PIS for energy efficiency improvements, residential energy property expenditures and home energy audits under § 25C (Energy Efficient Home Improvement Credit) is December 31, 2025 (instead of December 31, 2032).
- REPEAL OF 5-YEAR MACRS: Removes the ability to utilize 5-year MACRS schedules under § 168 for “energy property” described in § 48.
- Property eligible for a credit under §§ 45Y and 48E would remain eligible for 5-year MACRS.
- ENERGY EFFICIENT COMMERCIAL BUILDINGS DEDUCTION: Deduction for energy efficient commercial buildings is eliminated by adding a new BOC deadline of June 30, 2026.

*Subject to increase by Treasury no later than December 31, 2027, taking into account domestic geographic availability, supply chain constraints, domestic processing capacity needs and national security concerns
- GUIDANCE ON CALCULATION: Prior to promulgation of new guidance from Treasury (required by December 31, 2026), for purposes of calculating the Material Assistance Cost Ratio, the statute permits reliance on:
- IRS Notice 2025-08 (relating to certain safe harbors for domestic content adder calculations), but scope of such reliance is not yet clear; and
[Akin Note: This guidance only applies to §§ 45Y and 48E projects, and thus there is no current guidance for calculation of the Material Assistance Cost Ratio in the context of § 45X credits. Further, it is also not clear the extent to which IRS Notice 2025-08 may be relied upon for these purposes. For example, it is not clear whether the universe of manufactured products that must be tested limited to the manufactured products and components thereof identified in IRS Notice 2025-08 or whether “production costs” can be included if all of the MPCs for an APCs are not manufactured by a PFE.]
- IRS Notice 2025-08 (relating to certain safe harbors for domestic content adder calculations), but scope of such reliance is not yet clear; and
-
- Supplier certifications are required to be made in a manner consistent with Treas. Reg. § 1.45X-4(c)(4)(i) and contain:
- the supplier’s EIN or similar identification number issued by a foreign government;
- be signed under penalties of perjury;
- be retained by the supplier and the taxpayer for a period of not less than six years and provided to the IRS upon request; and
- be made from the supplier from which the taxpayer purchased any manufactured product, eligible component, or constituent elements, materials, or subcomponents stating:
- such property was not produced or manufactured by a PFE and that the supplier does not know (or have reason to know) that any prior supplier in the chain of production of that property is a PFE;
- for purposes of § 45X, the total direct material costs for each component, constituent element, or subcomponent that were not produced or manufactured by a PFE; or
- for purposes of §§ 45Y or 48E, the total direct costs attributable to all manufactured products that were not produced or manufactured by a PFE.
- Supplier certifications are required to be made in a manner consistent with Treas. Reg. § 1.45X-4(c)(4)(i) and contain:
- EXCLUSION FOR CERTAIN MANUFACTURED PRODUCTS:
- For purposes of §§ 45Y and 48E, calculations exclude the cost of any manufactured product if (i) acquired pursuant to a binding written contract entered into before June 16, 2025, (ii) PIS in a facility that BOC before August 1, 2025, and (iii) PIS before January 1, 2030 (or before January 1, 2028 in the case of wind and solar facilities).
- For purposes of § 45X, calculations exclude the cost of any eligible component or constituent element, material or subcomponent if the constituent element, material, or subcomponent is used in a product sold before January 1, 2027.
- Treasury is instructed to issued regulations or guidance as may be necessary to prevent abuse of this exception through “stockpiling”.
