President Donald Trump on 4 July signed the “One Big Beautiful Bill Act,” a wide-ranging tax and spending package that cleared Congress the previous day. The law accelerates the phase-out of several clean-energy incentives created under the Inflation Reduction Act, signalling a policy shift away from federally backed electrification. The most immediate change is the end of the federal clean-vehicle tax credit. Buyers now have until 30 September 2025 to take delivery of an eligible electric vehicle in order to claim up to $7,500 on new models and $4,000 on used ones; the incentives vanish entirely after that date, three months sooner than previously planned. Beyond transportation, the legislation shortens or eliminates production and investment credits for solar, wind and other renewable projects, and scraps fuel-economy penalties that had pressured automakers to boost fleet efficiency. Supporters say the measure reduces federal spending, while critics warn it will slow U.S. adoption of low-carbon technologies. Automakers are already responding. Tesla is sending emails and texts urging customers to close purchases before the deadline and has added a prominent banner to its website. Ford introduced a “Zero, Zero, Zero” summer sale—no down payment, 0% financing for 48 months and zero payments for 90 days—while extending its free home-charger offer through 30 September. Barclays analyst Dan Levy expects a surge in EV sales ahead of the cutoff followed by a sharp drop once the subsidy expires.
