New York State Tax

I've now done the computations for my NYS tax. I'm filing as a part year resident as I moved to Australia on 13th September. However, because I was losing money trading in the latter part of the year my NYS AGI (adjusted gross income) is almost as great as my federal AGI ($51,413 vs. $52,222). My total taxes come to $2652 but only $1588 was withheld. So including a 44.31 estimate tax penalty I owe $1108.
