The Impact of Ending EV Tax Credits: Lessons from Germany and US Projections

The United States recently witnessed the cessation of its federal electric vehicle (EV) tax credits, a policy that significantly bolstered the adoption of EVs by reducing their initial purchase price. These credits, enhanced by the 2022 Inflation Reduction Act, offered buyers up to $7,500, playing a crucial role in making electric vehicles more accessible and instilling confidence in automakers regarding sustained demand. However, with these incentives now gone, the market faces uncertainty, especially given that battery-electric vehicles still constitute a minor segment of overall new car sales in the country. This shift prompts a critical look at how similar policy changes have affected other major markets, particularly Germany, to anticipate the trajectory of the US EV landscape.
Transportation remains a substantial contributor to greenhouse gas emissions in the United States, accounting for approximately 30% of total emissions from various modes of transport. The discontinuation of federal subsidies for EVs therefore carries significant implications for national climate objectives. While the long-term cost of owning an EV can be lower than that of a gasoline-powered vehicle due to fuel savings, the higher upfront cost has always been a barrier for many consumers. This is precisely why governmental incentives, such as tax credits or rebates, have been vital in stimulating the transition to electric mobility.
Germany's journey with EV incentives offers a pertinent case study. In 2016, Germany launched a national program providing grants of up to €6,000 for new battery-electric or plug-in hybrid vehicles. This program successfully encouraged EV sales for several years. However, the German government gradually began to scale back these credits, first ending support for plug-in hybrids in 2022, then removing eligibility for commercial buyers in September 2023, and finally, abruptly halting the entire program in December 2023 with minimal notice.
The impact of Germany's policy changes was immediately evident in monthly sales data. Each instance of reduced public support was preceded by a surge in sales as consumers rushed to utilize the remaining incentives, followed by a sharp decline. For example, January 2024 saw roughly half the number of battery-electric vehicles sold in Germany compared to December 2023. This pattern of 'boom-bust' cycles provides a clear indication of what the US market might experience in the coming months. Already, the US has seen the 'boom' phase, with EV sales rising in August and September as buyers accelerated their purchases to take advantage of the expiring credits. Analysts now predict a significant slowdown, potentially dropping EV sales to very low single-digit percentages.
Experts, including Robbie Andrew from the CICERO Center for International Climate Research, highlight that while localized effects around policy changes are expected, the duration of the decline and the speed of recovery are the critical unknowns. Many researchers had previously expressed concerns that Germany's subsidies were ending prematurely, particularly given that EVs comprised a larger share (20%) of new vehicle sales in Germany compared to the US at the time. This concern proved valid, as Germany experienced a sustained backslide in EV growth after the subsidies ended, with battery-electric vehicles making up 13.5% of new registrations in 2024, down from 18.5% the previous year. The UK even surpassed Germany to become Europe's largest EV market.
Although Germany's sales have shown some improvement this year, reaching record highs in the first half, a substantial acceleration is needed to meet its ambitious goal of 15 million registered battery-electric vehicles by 2030, a figure that stood at only 1.65 million as of January 2025. For the US, early projections suggest that the absence of federal tax credits could severely impede progress on EV adoption and, consequently, on reducing emissions. One analysis by Princeton University's Zero Lab estimates that without these credits, battery-electric vehicle sales could be approximately 40% lower by 2030 than with continued support. While some individual US states offer their own incentive programs, the lack of comprehensive federal backing means the US risks falling further behind global EV leaders like China, effectively leaving low-hanging fruit on the tree for climate action.
