My 2 cents.
Im very surprised to see these two comments posted here. I have been using this company for over 9 years now and i will tell you thing that is they are honest and upfront when comes to taxes. They will tell you whats right and whats not and as far as knowledge goes, never felt it was lacking or had issues. They have been in business over 12 years as far as I can tell as a lot of my older friends from Cognizant filed through this firm they all seem to have no complain.
Hope you are not one of their competitors and trying these tricks to disrepute them.
