My husband had done our taxes with Turbo Tax for years and loves it. He just told me that it checks everything you do before it will let you e-file, so it's nearly fool proof for him. It asks you questions and makes sure you remember to put down things you might forget on your own. After it's sent in it's also checked again before you get the notice that all is well and your returns are on the way. We do pay extra to e-file, but returns are so quick and easy, it's worth it to us. So, to answer your question, no, for us there is no reason NOT to use Turbo Tax

He says after you use it once, it seems easier
