State tax filing

And do not get confused by the term "custody" in the divorce decree.   As I pointed out in the long answer above, with IRS cites, the term "custody" for *tax* purposes only means the parent who the child spent 183 (or more nights) with during the tax year and has nothing to do with "custody" that a court might order.    (This is a case of one word with two totally different meanings depending how it is used.)
