Maybe a notch higher than a tax protestor, but not much higher. So they don't comply with US tax law, how should they be treated. Is the defense "but I didn't know" valid for expats?
But why
would they know? The USA is literally the ONLY industrialized country on earth that does this. The only one. Why should it be "common knowledge" that they have a filing requirement? I see at least a dozen college kids every year who live here, who have always lived here, who don't even have a basic understanding of their own filing obligations.
Remember that even Former Secretary of Defense Donald Rumsfeld, sends a letter to the IRS
every year along with his tax return, (you can google this) stating that he has basically no idea what he's filing and that he's not sure that his return is correct. And this guy worked at the highest level of US government. Why would a citizen that left the country when they were 2 YEARS OLD think they were doing anything wrong? So now they're criminals?
Some of you guys have forgotten what it was like
before you became tax pros. This board exists so we can ask each other questions, because even though we're professionals, the IRC still mystifies us--how do you think it feels for someone who doesn't have our experience? Seriously, ease up.
