US IRS Publishes New Tax Credit Guidance on Renewable Energy
The U.S. Internal Revenue Service (IRS) has published new tax credit guidance on renewable energy just weeks after the Trump administration accelerated the expiration of numerous green energy-related tax credits via a massive spending and tax bill, plunging the domestic green energy space into crisis.
Dubbed the Big Beautiful Bill, the spending legislation set the expiration date for most green energy subsidies and tax credits to August, effectively bringing America’s renewable energy tax credit program to a sudden close. The IRS is now releasing new tax credit guidance to help the green energy sector navigate the new, post-Big Beautiful Bill landscape.
On August 15th, the federal agency published Notice 2025-42, which establishes critical standards for solar and wind projects in the country that want to qualify for tax credits outlined in the Internal Revenue Code’s Sections 45E and 45Y.
With the Big Beautiful Bill signed into law, wind and solar energy projects that begin construction after July 4th, 2026, or commence operations after 2027 won’t have access to the tax credits that have largely supported America’s ongoing transition to renewables. Consequently, projects looking to tap into these credits and subsidies have a very narrow window to apply before they disappear forever.
Developers now have a limited timeframe that is growing narrower by the day to apply for renewable energy tax credits and secure the capital they need to launch their renewable energy projects.
For the past decade, green energy projects in the U.S. have tapped into federal tax credits to offset the high costs of constructing solar farms, wind facilities, and other renewable installations. As developers rush to apply for the credits before their window closes, they will have to consider the IRS’s new guidance and adjust their strategies accordingly.
The IRS has now established that construction of green energy projects will be considered to have officially begun when physical labor of a ‘significant nature’ starts. Developers will be eligible to receive tax credits once the physical construction work has begun, the IRS clarified, and tax credits will be issued based on the ‘nature of the work’ conducted instead of the costs incurred.
For instance, the IRS will acknowledge that work has begun on solar projects once the installation of structures or racks for mounting the solar panels starts. The notice gives green energy projects clear timelines that they can use to launch their projects and ensure they leverage federal tax benefits before they run out.
For renewable energy developers, the new IRS guidance delivers both relief and urgency in equal measure. The agency’s practical approach to defining construction commencement provides much-needed certainty after months of regulatory limbo.
However, the tightened safe harbor restrictions for larger projects and the looming expiration of tax credits create a high-stakes environment where timing is everything. Projects above 1.5 MW now face additional hurdles, forcing developers to choose between rushing to meet September deadlines or accepting more stringent compliance requirements.
While industry leaders appreciate that the IRS avoided even more restrictive interpretations, the reality remains stark: this may be the final opportunity to secure federal renewable energy incentives for the foreseeable future.
With the expedited expiry of renewable energy incentives in the U.S., companies like PowerBank Corporation (NASDAQ: SUUN) (Cboe CA: SUNN) (FSE: 103) now have to use their innovativeness to deliver cutting-edge products that are competitively priced to lure consumers.
