invalid return

share what is the reason for return become invallid 

Yes, you can file rectified return for AY 2016-17 u/s. 139(4) even now......

agree with  Respected Sir Dhirajlal Rambhia

Forget the old filed return it is invalidate........

But whatever defects were there, remove them and file belated return as original.......

If required file ITR 4 (AY 2016-17) with P&L acc with BS.
