I filed my taxes in February, and they say it'll be processed within 2-6 weeks. 8 weeks later, they sent a demand letter for "more documentation." Specifically: Innovative Motor Vehicle Credit - A copy of the vehicle history report (such as one available from CarFax) for used vehicle. They need me to buy a CarFax for a used EV I bought? WTF?! So ridiculous. And if I did this today, they'll delay another 3 months and then ask for something else. I went this route when I bought my Nissan Leaf a few years ago, and ended up getting a credit half of what I calculated I was due. That year they asked for all sorts of stuff about my purchase (which I had already attached to my original return) and 6 months later I got screwed. This year they're also asking for my W-2 and 1099s again, which, shocking, I had already included with my return. Is this a calculated effort to not pay out the credit? I know lots of others have experienced problems over the last years too.
