The $7,500 tax credit that car shoppers can use for new EV purchases is set to expire at the end of September, according to the tax and spending bill that passed the House of Representatives on Thursday.

Sales are likely to dip below forecasts but not completely bottom out thanks to an array of new models and incentives from states and dealers.

The massive tax and spending cut bill that Congress passed Thursday ends federal tax incentives for electric vehicles. Buyers have until Sept. 30 to qualify for the federal tax credits on EVs before they are terminated. But experts say there are still strong financial reasons to consider buying the vehicles even without those incentives.
