If I revise my ITR, do I need to verify it again?
Yes you will need to e-verify your revised ITR or send both original and revised ITR for physical verification to CPC Bangalore. The reason why you need to resend the ITR for verification is
because filling a revised ITR means you are in a way withdrawing your original
ITR and submitting the revised return as your ITR.
The revised Income Tax Return (ITR) that you file will be like another return, even though it is a revision to your original return. So, you will need to verify it once you submit the same. The procedure for verification will be the same as the one you followed for your original ITR. Verification can be done online using your bank account or even using your bank ATM.
