There's some discussion on doing away with Income Tax in India altogether. I think it's a bad idea. I'm not an expert but here's my take.

1. IT has been a way to subsidise goods and services for then poorest of poor. Through these subsidies, the economically backward section of our country make ends meet.

2. Removal of IT means the government cannot fund subsidies.

3. So they will go the indirect tax route. All goods and services will be more expensive - for everyone, including the poor.

@wabbster Income from IT is very small also a number of people face difficulty in filing returns..my guess is that only employers will deduct IT and they may remove the tedious job of filing returns for aam admi.instead it will be reversed they will let people know how much IT they need to pay
@harshacgh Also, employers who do TDS, give you form 16. Upload it to a site like cleartax, and everything get fed into the system almost immediately.
