Before going down that route, keep in mind that you are obliged to file taxes on your global earnings, but if your "foreign" earnings are taxed at a higher rate than they would in the US and that country has unilateral reciprocity agreements (most places you would be thinking of going would meet both criteria) and you don't have any US income, then you have to file but don't pay anything. If any of the previous points isn't met then you will have to pay the difference. Basically Americans always pay at least an American tax rate, no matter where they are.
This sounds like the blasphemy punishments for leaving a religion or cult.
What’s the point of that?
Of course, it's still obviously worth it since your children won't have to pay the inheritance tax again...
(I'm an American in Canada, so I've had to become familiar with all of the above as applied to my case.)
- you spent over 330 full (midnight-midnight) days outside the US + its territories, with some important but clear exceptions for things like traveling
- you are a "bona fide" resident of another country; this involves an review by a US government official. typically these people pay taxes in another country, send their kids to school there, etc.
"Times are not good here. The city is crumbling into ashes. It has been buried under a lava flood of taxes and frauds and maladministrations so that it has become only a study for archaeologists. Its condition is so bad that when I write about it, as I intend to do soon, nobody will believe I am telling the truth. But it is better to live here in sackcloth and ashes than to own the whole state of Ohio." - Lafcadio Hearn (1850 - 1904)

Moreover, some countries like Finland require you to pay taxes on worldwide income for a number of years after you're no longer a resident of the country and only then granting you tax freedom from income sourced outside of the country. And there's no amount of income you can exclude like the USA's $108k or whatever the figure is currently.
