Perhaps most immediately impactful are the sweeping policy changes coming to electric vehicles and renewable energy. Federal tax credits worth $7,500 for new EVs and $4,000 for used EVs will vanish on September 30th, alongside commercial vehicle incentives worth up to $40,000 per vehicle. Renewable energy isn't spared either—rooftop solar installation credits expire at year's end, while wind and solar farm incentives in place for decades will disappear for projects after 2027. For consumers contemplating an EV purchase or solar installation, the clock is ticking on significant potential savings.
