Across all cities, there are a number of CAs and audit consultants, who could file your tax returns at a fraction of the cost charged by these online filing agencies. Plus the biggest advantage is that the CA/Audit consultant will take care of all the filling of the form and filing the same with the ITO.
With online filing, you are doing all the work by yourself and still end up paying agencies like tax smile etc a hefty sum of money. I mean, when you are paying the money, you expect someone else to take care of your work load. Right?
