Just checked on qualifying EVs for the federal tax credit and found some great news for those who signed our Ariya purchase contracts before 8/16.
The government web site states: "Preliminary guidance from the Internal Revenue Service addresses some important issues regarding vehicles purchased in 2022: If you entered into a written binding contract to purchase a new qualifying electric vehicle before August 16, 2022, but do not take possession of the vehicle until on or after August 16, 2022, (for example, because the vehicle has not been delivered), you may claim the EV credit based on the rules that were in effect before August 16, 2022."
It does not mention when you have to take possession specifically. Also, the web site now shows the Ariyas as qualifying for the $7,500 tax credit.
