ITR filing is PAN based which is unique and completely separate. Every individual has to file the ITR separately based on his residential status and total income earned
Filing of ITR depends on the residential status and total income earned during the financial year (i.e. from 01.04.2XXX - 31.03.2XXXX). Assuming you went outside India for employment purposes then if you were present less than 182 days during the financial year then your residential status would be treated as NRI
