WASHINGTON—Republican Sens. Joni Ernst of Iowa and Mike Braun of Indiana are proposing to limit the federal tax credit for electric vehicles (EVs) to those costing $45,000 or less and end the subsidy entirely for affluent buyers.
Depending on the price of the EV purchased, the tax credit allows buyers to deduct between $2,500 and $7,500 from their federal taxes. The credit first went into effect in 2011.
