My Suggestion is to bring income tax filing to mobile platform channel . I suggest the department to create a mobile application and place it in respective mobile platform app stores.MY Following to points will support the need 1.Since now there is no concept of downloading a excel and uploading it back with details updated .Its easy to enter the details in screen in mobile application and submit.2.Also the e-verification can be done by sending otp to the number and app picking automatically.
