So, I have signed up for a tax refund transfer shop, and after reading the guidelines, it doesn't sound bad at all. (I know, famous last words). I have one question, for anyone who has ever done a tax preparation shop: How do you handle the issue of them seeing your 10-99 form from the Mystery Shop companies you work for? Doesn't that clue them in that you are possibly "shopping" them at that very moment? The guidelines don't even mention this subject.
