Taxspanner is one of the wendors in my office for filing returns. They have some tie-up with Hewitt "to get more business"... It is easy to file via the IT website...But if one worked for two companies duing a financial year and has two Form-16, there are chances that you may face troubles. I am still struggling clear the mess created in 2010-11 because of two form-16. Over five visits already done to the Income Tax office, Hebbal.. When it is done by a professional agency, we can at least hope that they do it properly. When it comes to IT, we IT folks are pretty bad!
