You may have heard that there was recently one of those budget showdowns and the Republicans held a bunch of tax credit extensions as hostage against something or other. The big hoopla was over a payroll tax cut extension. But there are over 60 total tax credits due to expire on Saturday (Dec 31). The payroll tax cut was extended for two months, the others are being left to die.
Three of them were explicitly for electric vehicles: a) EV charger tax credit, b) EV conversions tax credit, c) the $2500 tax credit for electric two- and three- wheelers
I'm sure that John is perhaps looking into the last of those provisions.
