I have filled my tax return through them since last two consecutive time and guess what I'm stuck with my both both year return. And wait, best part is yet to come. If you e-file got stuck at any point (no matter whose mistake it is), then it's you who has call the panful IRS support team and what they will do is that simply calling you to convenience you that they can't do anything. I feel lot of agony and no idea how to express. So don't get stuck with these guys
