A property was sold in AY-2011-12. The property was co-owned by around 10 persons. One of the co-owner was selected for scrutiny and there was revision in the cost of indexation. Now the assessment order has asked all the co-owners to file a revised return and pay taxes accordingly. But, e-filing is not possible. The error says time limit for this AY is already over. Kindly guide as to what has to be done, should it be filed manually?
