you can claim such loss for current year but you will have to do calculations go back ward than claim the loss for current.
you can carry forward such loses to 8 yrs.
One more important condition is return should be filed before due.For returns already filed if you have file returns U/S 139(1) time limit and returns have not been assessed by Income Tax department than such returns can be revised and you can claim.
Hope these will help you,However these are my views please take a note of that.
