Hi folks. Got my Model S a bit over a year ago. I believe we are eligible for $7,500 income tax credit (federal) as well as $1,750 (PA State rebate, first 250 applicants). I submitted these when I filed my taxes last year. I did get the $1,750 from the PA State, but have not heard back at all for the federal rebate/incentive. Any suggestions/ ideas/ experiences? Is there a way to check the status? Thank you.
