So it would seem that there has to be enough federal tax liabilty to cover $15k for two cars. If both cars are registered under the wife's name and my name jointly, then I would assume that either can claim one or both? Would it be best to put both names on both cars or only one on each?
I live in CA and their state rebate has an income limit. I am not sure how this will play out with state lawmakers right now. Would this be independent so that if one person who has enough tax liabilty to claim both on IRS but now makes more than state limit, can the other person claim both cars for CA?
