It is to be noted that in case of F.Y. 2008-09, you can file ITR to claim refund. That ITR can be filed only upto March 2010. BUT, you'll be paid Interest on refund only from the date of filing return as it is a belated return. Had it be timely return, i.e. if had been filed before July 2009, Interest would be given from April 2009 onwards, irrespective of the date of filing return.
