Are you saying taxpayers aren’t getting those breaks anymore?
Depends on the manufacturer, Tesla is about used up.
Buyers of qualifying plug-in electric vehicles (EVs) may be
able to claim a federal income tax credit of up to $7,500.
The tax credit phases out once a vehicle manufacturer has
sold 200,000 qualifying vehicles. Tesla and GM have
reached this threshold, and credits for Tesla and GM
vehicles will begin phasing out in 2019.
