Thank you so much for the reply, Mr.Sorav. I shall get in touch with you if any further clarifications are required. 

In case of  a private family trust - if the income for the year is NIL , is it still mandatory to file ITR-5? Or is it advisable to file a NIL return even when income is below minimum exemption slab?
