This is the reply i got frmo ACES.

Bit strange as the last date for filing returns for Apr-Sep 2015 is 25th Oct 2015

Dear sir,

Ticket no: SD00420203

So far notification has not been released for the return period (Financial Year 2015-16).

For further clarification , we request you to contact local jurisdictional officers.

Regards,

Nasrin
