It would be easy to make an honest mistake though. Even for a CPA. After I settle down I go over my federal and state returns line by line. I understand most of it except this year I didn't know how to treat a certain kind of income and my CPA had to find out.
Many pitfalls is right. Most of those pages don't apply to most of us. I shudder to think if they take charge of Obamacare how taxpayers will deal with it. There will be a lot of angry people.
That's me. I report everything, even if someone hands me a $100 bucks for doing something for them. Otherwise, I wouldn't be on FR and even mentioning the IRS... lol
