For example US citizens who work overseas get an exemption for the first $75,000 a year of income. And when you also take into account the double taxation treaty and the fact that UK taxes are higher than US taxes, then it really would not be worthwhile for the IRS to chase such people down.
However if that person happens to later become rich and famous, then Uncle Sam might decide to take a special interest in their success.
From personal experience you are still expected to do an annual tax return and declare all bank accounts, property, bonds, stocks etc. etc. regardless of whether you end up owing nothing. And 75k is easily exceeded in certain jobs. Plus, if like some, you end up in the middle east in a zero-tax environment…..
I acquired British citizenship when I was in my mid-40s, and ‘expatriated’ a few years after. Even now, alarm bells start ringing when I deal with non-US financial institutions, as they assume you are still a US citizen (by birth) when you declare your birthplace.
