The House GOP Tax Proposal Would Effectively Kill The IRA

The Ways and Means Committee released its proposed budget language, and it’s not pretty for clean energy.

The House Ways and Means Committee, which oversees tax policy, released its initial proposal to overhaul the nation’s clean energy tax credits on Monday afternoon. These are separate and in addition to the extensive cuts to Inflation Reduction Act grant programs proposed by the Energy and Commerce Committee, Transportation Committee, and Natural Resources Committee in the past few weeks.

Here’s a rundown of the tax credit proposal, which, at first glance, appears to amount to a back-door full repeal of the climate law. There’s a lot that could change before we get to a final budget, let alone have a text head to the Senate. We’ll have more analysis on what these changes would mean in the days and weeks to come.

Cut the EV tax credit … mostly

The text proposes ending the tax credit for new EVs (that is, 30D) on December 31, 2025 — with one exception. The credit would remain in effect for one year, through the end of 2026, for vehicles produced by automakers that have sold fewer than 200,000 tax credit-qualified cars between 2010 and the end of this year. That means that no Teslas would qualify for the tax credit next year, as the company has sold far more than 200,000 tax credit-eligible vehicles. A new entrant to EVs, like Honda with its Prologue model, will likely still qualify.

The committee also proposes ending the tax credit for used EVs (25E) and commercial EVs (45W) by the end of this year. This would effectively end the “leasing loophole” that allowed Americans to redeem the tax credit on vehicles that didn’t qualify for 30D because they didn’t meet domestic content requirements, meaning consumers could get discounts on leases of a wide range of makes and models.

Lastly, the draft proposes terminating the tax credit for residential EV chargers (30C) at the end of this year.

Early phase-out for tech-neutral clean power

The GOP has proposed an early phase-out of the technology-neutral production and investment tax credits, which subsidize zero-emissions power generation projects including wind, solar, energy storage, advanced nuclear, and geothermal. It also proposed significant changes for the years they remain in effect.

Currently, new clean electricity projects can earn a 2.75 cents for every kilowatt-hour they produce for the first 10 years under section 45Y of the tax code. Alternatively, project developers can get a 30% investment tax credit (48E) on new projects. The Inflation Reduction Act scheduled both of these programs to phase out beginning in 2032, and expire at the end of 2035. It included a major caveat, however: that this phase-out would only happen if greenhouse gas emissions from U.S. power generation fell below 25% of 2022 levels. Otherwise, the tax credits would be maintained at their initial amounts until this target was met.

Under the GOP proposal, both credits would start to phase down in 2029, and new projects would no longer be eligible for either credit beginning in 2032. The proposal also cuts out a key provision that would have grandfathered many more projects into the tax credit. Under current law, a project only has to start construction within a certain year to qualify for that year’s tax credit amount. The draft text changes this, requiring a project to be “placed in service” before 2032 in order to qualify.

A separate tax credit for existing nuclear power generation (45U) would also phase down on the same timeline, despite Trump and other Republicans’ interest in boosting nuclear energy.

Transferability, we hardly knew ye

“Transferability” supercharged the nation’s clean energy tax credits by allowing project developers with low tax liability to sell their credits to another entity that stood to benefit from them. Previously, developers could only monetize their unusable tax credits through complicated tax equity deals.

Recipients of a wide range of tax credits, including those for clean manufacturing, clean fuels, carbon capture, nuclear power, and hydrogen, can all take advantage of transferability. The provision channeled new capital into the climate economy as corporations looking to reduce their tax liability began scooping up tax credits, indirectly helping to finance clean energy projects. It also helped lower the cost of wind and solar, as developers could earn a premium on tax credits compared to what they got for tax equity transfers, because the whole transaction was cheaper to do.

The proposal would get rid of this option across all of the tax credits beginning in 2028.

Foreign sourcing limits on everything

The proposal would also impose new sourcing requirements across all of the tax credits, prohibiting developers from using components, subcomponents, or critical minerals sourced from “foreign entities of concern,” a term that applies to companies based in China, Russia, North Korea, or Iran. The consequences would be huge, as China dominates global markets for refined lithium, cobalt, graphite, and rare earths — key materials used in clean energy technologies.

Taking the wind out of clean manufacturing’s sails

The draft text would also terminate the clean manufacturing credit (45X) in 2032 — one year earlier than under existing law. Wind energy components such as blades, towers, and gearboxes would lose their eligibility sooner, in 2028.

Bye-bye credits for energy efficiency, heat pumps, and rooftop solar

The text proposes repealing three tax credits for residential energy efficiency improvements at the end of 2025. Starting next year, homeowners would no longer be able to claim the Energy Efficiency Home Improvement Credit (25C), which provides up to $3,200 per year for home energy audits, energy-saving windows and doors, air sealing and insulation, heat pumps, and new electrical panels.

It also proposes killing the Residential Clean Energy Credit (25D), which offered homeowners 30% off the cost of solar panels and battery systems to store energy from those solar panels. This credit also subsidizes geothermal home heating systems.

Both of these tax credits have existed in some form since the Energy Policy Act of 2005.

The third credit that would end this year is an up to $5,000 subsidy for contractors who construct new, energy efficient homes (45L).

The proposal would not repeal the energy efficiency tax deduction for improvements made to commercial buildings (179D).

Extension for clean transportation fuels

The Inflation Reduction Act created a technology-neutral tax credit for low-carbon transportation fuels, like sustainable aviation fuel and biodiesel (45Z). It operates on a sliding scale, depending on how carbon-intensive the fuel is. The credit is set to expire after 2027, however the GOP proposal would extend it for four years, through the end of 2031.

That said, it would also make a significant change to how the credit is calculated, making it much easier for projects with questionable emissions benefits to qualify. Under the Biden administration, the Treasury Department issued rules that said producers had to account for the emissions tied to indirect land use changes resulting from fuel production. That meant that corn ethanol producers, for example, had to account for the expansion of croplands resulting from the increase of biofuel production and use — which would, in most cases, disqualify corn ethanol from claiming the tax credit. But under the GOP proposal, producers would explicitly not have to account for indirect land use changes.

Clean hydrogen canceled

The GOP proposal would deal a rapid and ruthless death blow to the 45V clean hydrogen production tax credit, requiring developers to begin construction before the end of this year if they want to claim it.

‭Carbon capture largely unchanged

Other than ending transferability, the text makes no changes to the 45Q carbon capture and sequestration tax credit.

Labor, energy communities adders untouched

Most of the tax credits have provisions that allow project developers to qualify for higher amounts if they pay prevailing wages, hire apprentices, build in a qualified “energy community” or a low-income community, or use a certain percentage of domestically-produced materials. This initial draft from the GOP would not change any of those provisions.

Trump Tightens Tax Credit Rules For Renewables

Current conditions: After briefly strengthening into a Category 5 storm, Hurricane Erin continues toward Puerto Rico as a Category 4 • China is reeling from flash floods that killed 10 in Inner Mongolia on Sunday • Spain is battling 20 major wildfires as blazes across Europe displace thousands.


THE TOP FIVE

1. Trump tightens the vise on wind and solar tax credits

The Internal Revenue Service released guidance on Friday for wind and solar projects attempting to access the federal tax credits that start phasing out next year. For more than a decade, renewable developers needed to show only that they’d spent 5% of the total cost of the construction to qualify in a given tax year. Once the new rules kick in next month, almost all new projects will need to actually begin physical construction to be eligible. The change comes in response to an executive order President Donald Trump issued after signing the One Big Beautiful Bill Act, which directed the Treasury Department to raise the hurdles for wind and solar developers to tap what remained of the federal tax credits the new law had dramatically curtailed.

Now We Decide the Future of U.S. Climate Policy

On the third anniversary of the signing of the Inflation Reduction Act, Heatmap contributor Advait Arun mourns what’s been lost — but more importantly, charts a path toward what comes next.

Today, the Inflation Reduction Act would have turned three years old — if it hadn’t been buried alive in a big, beautiful grave. While the IRA was a hodgepodge of programs salvaged from President Biden’s far more ambitious Build Back Better agenda, it still represented the biggest climate investment in U.S. history. It catalyzed over $360 billion in energy and manufacturing investments and was expected to drive the installation of over 155 gigawatts of new solar and wind energy by 2030. And now Republicans have taken a sledgehammer to its achievements.

The timing could not be worse — not just for the climate, but also for the energy systems that we rely on. At a moment when the energy sector requires $1.4 trillion worth of upgrades by 2030 just to keep up with rising energy demand and increasingly erratic weather, Republicans have instead delivered a one-two punch of tariffs and tax hikes, sabotaging the industrial base required to deliver those investments and raising the retirement age of our power generation fleet.
