Dear Friend
Beware:
I strongly advise you all to refrain from filing your tax returns through IBSN.
They not just delayed the entire processing, but over charged for the service that I never availed. It took about 10 months and series of email chain when they finally send me a PDF document to paper file myself.

They never cared to inform me the my tax was not yet Filed. They still owe me $40 which I over paid and I have had called them several time and finally let go of the amount.

1. horrible service (their consultant are stationed in HYD, and speak horrible english)
2. No answer via phone. (I probably called them 100 of times on their 1800 number, sometime put on hold for about 30 - 45 min...i am not exaggerating).
3. Never respond to emails.
4. They do some illegal way to get you a higher refund and God forbids if you get a query on your TAX filing, forget about ever working in US again..

I was their customer for last 3 years, but this year I am going to file through turbo tax...

All the best with your TAX filing.
