Expanded EV tax credit questioned by key swing vote senator Manchin of W.Va.

Last year, many Democrats in Congress and President Joe Biden proposed boosting EV tax credits to up to $12,500 — including a $4,500 incentive for union-made, U.S. assembled vehicles.

Manchin — whose state is home to a major non-union Toyota Motor Corp. engine and transmission plant — earlier opposed the union-only incentive.

Biden also backed a 30 percent credit for commercial EVs and a $4,000 used EV tax credit and making the current credit refundable at the point of sale.

Biden also wants to end the current practice of phasing out automakers’ tax credits after they hit 200,000 EVs sold, which would make Tesla Inc. eligible again for the current $7,500 credit.

Tax credits for General Motors vehicles expired in April 2020 and Toyota said this month it expected its credits would expire by the end of 2022 after it hits the cap. Ford Motor Co. sold nearly 160,000 EVs through the end of 2021 and could hit the cap this year.
