Maybe someone smarter than me can assist. I'd like to wait until Jan. 2nd to purchase my Volt because I will avoid property taxes in my state (Missouri). But by doing that, I won't be able to claim my tax credit until I file my 2017 taxes in 2018. Should I be worried that the credit may be gone by then or will I get credit for have purchased it before 200K were sold? Or will Trump kill the whole program...ha.
