First of all you read this DO NOT file your return through IBSN, its fraud company there just to GET YOUR MONEY and put you in TROUBLE OF AUDIT.
For my 2010 IRS return for my BAD LUCK i approaced the IBSN and started the activities and they were calling me for all the details and verifivation and i suppose to pay the fees. Once i paid the fees there were no calls and their phones were no reachable at all.
There was no response from the IBSN as they had highly customized my returns and i needed some changes to my return. Irrespective of calling multiple times and sending messages in their website there was no response. Finally i asked them not to file my returns using the website as there were no response them, for that also i never received a response.
Moral of the Story : TILL THE TIME YOU DONT PAY YOU ARE GOD, ONCE YOU PAID YOU ARE IN TROUBLE.
By the time all these were going on it was end of April and irrespective of asking them not to file, just to complete their work IBSN just blindly filed my return without sending any response to my commuincations or queries.
IRS Audited my returns in 2011 and i had to pay a lot of money due to the customizations IBSN did to my return. As a responsible Tax Service agency, they suppose to tell the clients/customers what can be claimed and what cannot be cliamed. But for IBSN they just need to make money and you face all the IRS issues later.
Once i received the IRS audit documents and i called the IBSN, They picked up the call (i think they thought another poor customer calling) and i told them about the IRS query. They asked me to send an email to the firstname.lastname@example.org. But i never received any response from them till today.
I had to pay all the IRS fine and settle the matter and had gone through all the troubles myself. IBSN just ignored all the communications as they DONT CARE about you.
Moral of the Story : DO NOT FILE YOUR RETURNS THROUGH IBSN AS YOU WILL END UP IN TROUBLE AND WILL HAVE TO PAY A LOT OF FINE AT THE END.
