When the reporting went from paper forms to fill in and mail, to online only, they also instituted sky-high penalties for preparers who fill out forms, from client documents, in good faith, and completely true so far as they have any knowledge. At that point, I started telling clients - you do it. Not me. Nope. Nuh-uh. Not ever. Someone gives me wrong info and I have to pay? No way, no how, not ever.
So yeah, I won't touch them because of possible vicious penalties.
