Unless someone knows different than me, based on the information provided I don't see any need to file a NY state return at all. For starters, you were *NEVER* a resident of NY. If anything, then at best you were a non-resident. Howevr:
- All of your income was physically earned in NJ as a full year resident of NJ. Therefore you DO owe state tax to NJ for the entire year for every penny earned as reported on the W-2.
- Not one single penny of income was earned in NY, even as a non-resident of NY. Therefore you have no tax liability what-so-ever to the state of NY and don't even need to bother filing a tax return.
Some areas of your post that contradict each other.
i was planning to move. indicates to me that you never did actually move to NY.
plans quickly fell apart and I had to move back to NJ. Contradictory to the above, as you can't move back, to a place you never moved away from in the first place.
Even if you did physically move your entire household to NY, 12 weeks isn't nearly long enough to establish residency. Not even close.
