Key Modifications to Energy Credits and Deductions under the One, Big, Beautiful Bill Act
The Internal Revenue Service (IRS) has issued FAQs (FS-2025-05, Aug. 21, 2025) providing initial guidance on modifications to various energy-related tax provisions under Public Law 119-21, 139 Stat. 72 (July 4, 2025), commonly known as the One, Big, Beautiful Bill Act (OBBBA). These FAQs are intended to offer general information to taxpayers and tax professionals expeditiously. While these FAQs have not been published in the Internal Revenue Bulletin and thus will not be relied upon by the IRS to resolve cases, taxpayers who reasonably and in good faith rely on them will not be subject to certain penalties, such as negligence or other accuracy-related penalties, to the extent such reliance results in an underpayment of tax.
These modifications specifically impact sections 25C, 25D, 25E, 30C, 30D, 45L, 45W, and 179D of the Internal Revenue Code. Future guidance is anticipated on other provisions affected by OBBBA.
