For the next ten years, electric vehicle buyers will continue to get up to $7,500 in tax credits toward new cars, while used EV purchases will be eligible for $4,000. The fine print is extensive. The source of the parts, point of assembly, vehicle price, manufacturer, and the potential car buyer’s income all factor into the EV equation.
