Dated March 17, 2025, the study, released by the REPEAT Project—a renowned Princeton University program dedicated to comprehensive analysis of environmental policy—paints a stark picture of the potential repercussions. While not every EV currently available in the U.S. market fully qualifies for the full tax credit due to stringent eligibility criteria, the study’s analysts firmly conclude that its outright removal would inevitably lead to a sharp decline in EV sales. This projected sales slump would, in turn, severely undermine the health and growth trajectory of U.S. manufacturing, particularly within the nascent EV and battery supply chain.
Jesse D. Jenkins, an assistant professor at Princeton and the influential project leader behind the REPEAT study, underscored the report’s unique contribution to the public discourse. In an emailed statement to Electrek, Jenkins noted, "The report is also the only analysis I’m aware of to date that draws the connection to U.S. manufacturing as well." This emphasis highlights a critical dimension often overlooked in broader discussions about EV incentives—the direct link between consumer demand stimulated by credits and the viability of domestic industrial investment and job creation.
The REPEAT Project’s findings are sobering. Without the financial incentive provided by the tax credit, EV sales are projected to plummet by a staggering 30% by the year 2027, with the decline accelerating to nearly 40% by 2030. Such a dramatic reduction in demand would consequently shrink the anticipated EV market share significantly, forecasting a drop from an expected 18% to just 13% in 2027, and from an ambitious 40% to a mere 24% by 2030. These figures represent a substantial rollback of the progress and investment made in accelerating EV adoption.
The ripple effect extends directly to the manufacturing sector. Analysts predict that this precipitous decrease in EV demand could lead to the complete shuttering or cancellation of 100% of all currently planned expansions for EV assembly plants across the United States. Furthermore, the report warns that between 29% and a staggering 72% of current battery-manufacturing capacity, critical for establishing a robust domestic supply chain and reducing reliance on foreign sources, could become redundant as early as this year. This scenario would not only halt progress but could also reverse significant investments already made by major automakers and battery manufacturers.
The federal EV tax credit, re-established and enhanced by the Inflation Reduction Act of 2022, serves as a cornerstone of the Biden administration’s ambitious agenda to combat climate change, bolster American manufacturing, and foster energy independence. The IRA, a landmark piece of legislation, earmarked hundreds of billions of dollars for clean energy initiatives, with the EV tax credit designed as a direct incentive for consumers to choose electric vehicles while simultaneously stimulating domestic production throughout the entire supply chain. Its primary purpose is multifaceted: to make EVs more financially accessible to a broader segment of the American population, reduce greenhouse gas emissions from the transportation sector, and create high-paying manufacturing jobs within the United States.
However, the credit, currently capped at $7,500, is not universally applicable to all electric vehicles on the market. It is meticulously structured with several layers of restrictions aimed at achieving specific industrial policy goals. These stipulations include:
- Price Caps: To ensure the credit benefits a wider range of consumers and doesn’t solely subsidize luxury vehicles, sedans must have a Manufacturer’s Suggested Retail Price (MSRP) of $55,000 or less, while vans, SUVs, and pickup trucks are capped at $80,000.
- Income Caps: To direct the incentive towards middle and lower-income households, purchasers must meet adjusted gross income (AGI) limits: $300,000 for married couples filing jointly, $225,000 for heads of household, and $150,000 for all other filers.
- Assembly Location: A crucial requirement dictates that the final assembly of the qualifying vehicle must take place in North America. This provision directly supports U.S., Canadian, and Mexican automotive manufacturing jobs and strengthens regional supply chains.
- Battery Component Sourcing: The most complex and evolving set of rules concerns battery materials. A certain percentage of the critical minerals used in the battery must be extracted or processed in the U.S. or a country with a free-trade agreement with the U.S., or recycled in North America. Additionally, a specified percentage of the battery components must be manufactured or assembled in North America. These rules are designed to reduce reliance on adversarial nations for crucial EV components, enhance energy security, and foster a domestic battery industrial base.
For the vehicles that successfully navigate these stringent requirements, the $7,500 tax credit can represent a significant discount, often making the difference between an affordable and an out-of-reach purchase for many consumers. For instance, as noted in the original report, the most affordable EV, the 2024 Nissan Leaf, could effectively cost as little as $25,505 with the credit, making it highly competitive with comparable gasoline-powered vehicles. This direct price reduction is a powerful motivator for consumers to overcome the typically higher upfront cost of electric vehicles.
While the Trump administration has indeed signaled its intent to dismantle policies perceived as detrimental to traditional fossil fuel industries and to roll back environmental regulations, the actual process of eliminating the EV tax credit is not as straightforward as a presidential decree. It would necessitate a coordinated legislative repeal by Congress, requiring a majority vote in both the House of Representatives and the Senate, followed by the President’s signature. This intricate legislative process implies that a direct, unilateral elimination by a President Trump would be highly improbable without significant congressional alignment.
However, even without a direct repeal, a future Trump administration could employ various executive actions and regulatory maneuvers to effectively undermine the spirit and impact of the IRA’s EV provisions. These could include:
- Delaying or Weakening Regulations: Slowing down or revising emissions standards that encourage EV adoption.
- Reinterpreting Eligibility Rules: Implementing stricter interpretations of existing battery sourcing or assembly requirements, inadvertently disqualifying more vehicles.
- Reducing Funding for Complementary Programs: Cutting appropriations for EV charging infrastructure development, research and development, or state-level EV initiatives.
- Trade Policies: Imposing tariffs or trade restrictions that impact the cost or availability of EV components, even those sourced from allied nations, thereby increasing production costs.
- Public Rhetoric: Consistent negative rhetoric surrounding EVs could dampen consumer enthusiasm and confidence, irrespective of financial incentives.
The broader implications of such a policy reversal extend far beyond individual vehicle sales and directly challenge the economic competitiveness of the United States in the global automotive landscape. Major automakers like Ford, General Motors, and Stellantis have committed tens of billions of dollars to transition their product lines towards electrification, building new factories, retooling existing ones, and investing in battery production. These investments, often predicated on the sustained policy support provided by the IRA, are designed to catch up with and compete against global leaders, particularly China, which has heavily subsidized its domestic EV industry.
The U.S. auto industry is currently undergoing its most significant transformation in a century. A sudden removal of the tax credit would send a chilling signal to investors, potentially causing automakers to reconsider or scale back these massive commitments. This could lead to a loss of market share to foreign competitors, hinder the development of a robust domestic EV supply chain, and jeopardize the creation of new, high-skill manufacturing jobs. While the transition to EVs does present challenges for some traditional internal combustion engine (ICE) related jobs, the overall economic strategy behind the IRA is to ensure that the U.S. leads in the next generation of automotive manufacturing, creating new opportunities.
Environmentally, eliminating the tax credit would undoubtedly slow the decarbonization of the transportation sector, which remains the largest source of greenhouse gas emissions in the United States. A reduced rate of EV adoption would make it significantly harder for the U.S. to meet its climate targets under the Paris Agreement and contribute to global efforts to limit warming. Slower EV uptake also means continued reliance on fossil fuels, with associated impacts on air quality in urban areas and national energy security.
While proponents of phasing out subsidies argue that the market should ultimately dictate technology adoption and that government intervention can lead to inefficiencies, the REPEAT study underscores that the EV market is still in a critical growth phase. Early-stage subsidies are common for emerging technologies to help them achieve economies of scale and become competitive with established alternatives.
In conclusion, the prospect of a future Trump administration eliminating the federal EV tax credit is more than just a political talking point; it represents a significant inflection point for the American economy, its manufacturing base, and its environmental commitments. The REPEAT Project’s study provides a stark, data-driven forecast of the potential consequences: diminished sales, stalled manufacturing expansion, and widespread job losses. While a direct repeal requires congressional action, the signaling of such intent and potential executive maneuvers could still severely dampen the momentum of the burgeoning EV industry. The debate over the EV tax credit is fundamentally a debate about America’s future industrial strategy, its climate leadership, and its ability to compete in the global clean energy economy. The decisions made regarding this critical incentive will resonate through the auto industry, labor markets, and the environment for years to come.
