In addition to a Federal government tax credit up to $7,500, consumers who purchase plug-in electric vehicles (PEVs) may also receive state government incentives which vary by state. Shown below are state incentives that can be quantified, such as tax credits and rebates, sales and use tax exemptions, reduced license taxes, title tax exemptions, and reduced registration fees. Colorado, Connecticut and Louisiana have the highest incentives for tax credits. New Jersey offers the only sales and use tax exemptions; and DC offers the only title tax exemption and reduced registration fee.

For calculation purposes, e.g., sales tax exemptions, the vehicle was assumed to have a value of $40,000, a weight of 3,500 lbs., and a 20 kWh battery capacity. Only the incentives listed in the columns above were considered. Other state incentives, such as high-occupancy vehicle lane exemptions and reduced toll rates are not reflected here. Also, incentives on the charging equipment, electricity discounts, etc., were not considered.
