IRS Finalizes Prevailing Wage & Apprenticeship Rules for IRA Clean Energy Credits (June 18, 2024, US)

The U.S. Department of the Treasury and IRS have issued final regulations on the prevailing wage and apprenticeship (PWA) requirements for increased clean energy tax credits under the Inflation Reduction Act (IRA). Released on June 18, 2024, these final rules clarify how taxpayers can qualify for a significant 5-times increase in the base amount of many clean energy incentives.

Why it matters

The final regulations provide definitive guidance on meeting PWA requirements, which are crucial for maximizing the financial benefits of IRA tax credits. For battery storage, grid infrastructure, and advanced manufacturing projects, this means that meeting specific labor standards (paying prevailing wages and employing registered apprentices) can dramatically boost project economics. For example, credits like the Clean Electricity Investment Credit, Qualifying Advanced Energy Project Credit, and Alternative Fuel Refueling Property Credit are subject to these rules. Failing to meet PWA requirements means only the base credit amount can be claimed, significantly reducing the incentive.

Who is affected

Developers, manufacturers, and project owners seeking to claim increased clean energy tax credits for projects such as battery manufacturing facilities, grid-scale energy storage, clean electricity generation, and advanced energy manufacturing. The Department of Labor determines applicable prevailing wage rates.

Key timing

The final regulations were issued on June 18, 2024, providing clarity for ongoing and future projects. There are limited exceptions where the 5-times increase can be claimed without meeting PWA requirements: for certain small facilities under 1 megawatt, and for facilities that began construction before January 29, 2023. Taxpayers must also meet specific recordkeeping requirements.
