Thanks for the info – could you explain that last part a bit more?
When filling out the NYS form (where I am filing as part year resident), I am asked if I have been taxed on the same income by another state – so for this question I would not be able to put the NJ income/tax paid on my non-resident NJ return? And also not able to put the KY income/tax paid on my part-year KY return since my domicile was KY at end of the year?
