It seems that the travel expense link only applies for temporary work or travel. I have a similar situation: I have a permanent W2 job in Massachusetts; rent an apartment in New Hampshire (cheaper than Massachusetts); but my family and mortgage are in North Carolina.
Should I still file State taxes in NC while I am filing Non-residency in Massachusetts, even though I did not earn any income in NC? Can I claim the NH apartment as a 'business expense' even though the Massachusetts job is considered a 'permanent' position?
