1) There should be a flowchart explaining the steps. Something like Enter information -> Generate ITR V -> Send it to CPC. I was lost when I was asked to post something somewhere and had to look up the process of e-filing on the net.
2) While entering information each text box/textarea has a information on the relevant field of Form 16. That should link to a pic to sample Form 16 highlighting the field. Somethings were ambiguous.
3) More information on what types of Tax Filings are covered. I had to ask you guys to ask about self employed tax filing (and you guys responded very fast, which was great) because I didn't find a FAQ.
4) Information on when do you have to pay and how much. I was never asked for any payment. Which is good, but I'm still kinda confused how that happened. :)
5) The step where it was submitting the information to the income tax website kept timing out. I guess it was maybe because the endpoint was not responding. I tried it the next day during working hours and it went through. You can maybe automate this by giving users an option to automatically retry.
Few questions I had after using it was.
1) Will you guys add support for digital signatures? 2) Will you also allow someone to apply for a digital signature and get it? 3) What is your business model? Do you charge a fee for each filing?
Overall I'd give you a rating of 4 (on a scale of 5). I wish there were more such utility services in India.
