There are assesses who donot have mail ids and are senoir citizens who donot have the computers at home or operate them any where.
In that case is it in order to file the return quoting the ID of his contact person for this purpose.?
Also can the same id be used for more than one person( just as for hosband wife who are assesses )to receive communication and to register each of the PAN Etc of group of persons.
