I bought a 2017 Zero SR this summer knowing the credit wasn't currently active so this is welcome news even if its inconvenient as heck!
I just filed my taxes yesterday.. should I amend them now or wait a couple months? Does Zero need to update the IRS before they'll accept my VIN as a valid credit, and doing so now would just get my amended return denied?
Who knows about this year.
But the IRS has a lot of things to change in their tax return computer forms and it has been my experience that fixing the EV credit form is about the last thing they will get around to doing. Also, I am pretty sure that until Zero provides them with a list of VIN numbers that were manufactured last year, you won't be able to enter the VIN for your bike into their automated form if you file electronically. However, you might be able to do so if you prepare your return manually and mail it into the IRS. By the time they get around to reviewing it, they will likely have that information by then.
My recommendation (and what I plan to do), since I have already sent in my return, is to wait until after April 15 when things have slowed down at tax preparers' offices, and file an amended tax return. After all, the money isn't going anywhere and if the government needs more, they can always print it up.
Of course, if you need the refund now then filing as early as possible would be the thing to do, but you will have to check with a professional (such as someone other than me) to find out when that can be accomplished.
