Permanent place of abode
In general, a permanent place of abode is a residence (a building or structure where a person can live) that you permanently maintain, whether you own it or not, that is suitable for year-round use. A permanent place of abode usually includes a residence your spouse owns or leases.
However, a residence maintained by a full-time student enrolled at an institution of higher education in an undergraduate degree program leading to a baccalaureate degree and occupied by the student while attending the institution is not a permanent place of abode with respect to that student. For additional information, see TSB-M-09(15)I , Amendment to the Definition of Permanent Place of Abode in the Personal Income Tax Regulations Relating to Certain Undergraduate Students .
Note: Special rules apply to military personnel and their spouses; see Publication 361, New York State Income Tax Information for Military Personnel and Veterans .
