U.S. IRA Clean Energy Tax Credits: List of Accelerated Termination/Reduction Schedules Under OBBBA

The "One Big Beautiful Bill Act" (OBBBA), enacted July 4, 2025, brought forward the termination or phased reduction (sunset) of numerous clean energy tax credits introduced under the 2022 Inflation Reduction Act (IRA). Key amendments include: (1) Section 30D (Clean Vehicle Tax Credit, up to $7,500) was fully terminated on "December 31, 2025," significantly accelerated from its original end-of-2032 schedule. (2) Section 45X (Advanced Manufacturing Production Tax Credit)—a support framework for North American production of battery cells/modules and critical minerals—begins a 25% annual phase-down starting January 1, 2027, with complete termination on December 31, 2029. (3) Sections 45Y/48E (Clean Electricity Production and Investment Tax Credits) were also amended to include stricter emissions reduction requirements and expanded FEOC restrictions.
