The article discusses the details and rules surrounding Federal EV tax credits for electric vehicles, outlining different scenarios for buying new, buying used, and leasing EVs. For new EV or PHEV purchases, vehicles must have final assembly in North America and meet specific criteria related to critical battery minerals and battery component sourcing, with tax credits up to $7,500. Used EV or PHEV purchases have lower income caps and a price limit of $25,000, with a potential tax credit of up to $4,000 based on the vehicle's value. Leasing a new EV offers the full $7,500 tax credit to the lessor, typically the automaker's finance division, without the same restrictions on assembly, battery sourcing, or income limits. The article also provides a list of vehicles that qualify for the federal EV tax credit and explains the eligibility requirements for used EVs. It highlights the importance of understanding these tax credits and the benefits they offer to individuals based on their vehicle purchase or lease preferences.
