Effectively US expats have to pay US tax only if they make over ~$150k a year abroad.
That’s very rare.
You’re talking about US Citizens working overseas paying US tax on their annual income.
I was talking about US citizens who change their citizenship and renounce their US citizenship. The analogy is that the government seizes a good chunk of any long-term profitable assets via capital gains taxes. It’s a forced valuation, as if it were a sale. Because, when you’re gone, you’re really gone.
That was introduced under Clinton.
