It is great for us. Better APIs, more stability, clear wind behind our backs for a more digitization, more tax payers, more transparency, no middlemen, more things in white.

The Government software isn't very simple to use if you have switched jobs, have HRA to claim, or have more deductions than you have declared to the employer.

Many people miss out on deductions (such as 80TTA) which we automatically account for.

Plus we reduce data entry mistakes, and the other things I pointed out in the original comment.

The existing site is simple enough. Digital India would probably help these guys with Aadhaar auth, FACTA link for NRIs, and unified API.

The issue with IT website is not simplicity or functionality -- it is the fact that it assumes you know what you're doing. Which is simple for a nominal case, but gets increasingly complex with a diversified income sources and portfolios.

Also the existing official site is good enough
