Can a loss return (Income Tax Return) be revised???

yes a loss return can be revised

sec 4 ref is 139(3)

it says that if a loss return is filed within a time specified u/s 139(1) then a loss return is valid and all the provisions shall apply which applies to 139(1)

139(5) says a return can be revised if it is made u/s 139(1) or 142(1)

Even those it is a loss return it can be revised.

but subject to original return must be filed with in due date 

A loss return can be revised, PROVIDED that the original return was filed within the due date.

Yes, it can be revised

Yes, it can revised.

Yes a loss return can be revised provided the original return is filed in time as per sec 139(5)

YES , CAN BE REVISED U/S 139(5)

Where the original return was filed within the due date specified u/s 139(1), then even a return of loss u/s 139(3) is deemed to be return filed under 139(1). Hence when you revise a return as per 139(5) then it steps into the shoes of the original return.. Hence it can be revised
