I don't have enough knowledge to know if my situation was unusual or not. But I certainly wish the bite had been less. Lol... Yes I did get credit for the foreign side of the income based taxes but still had a USA liability remaining with the net effect that my total tax load was greater than if it had been one country taxing instead of two.
Yes. When I lived overseas, the first $75,000 was free of US tax, but everything above that was double taxed, with credit for foreign taxes paid, up to a point that I never reached. However, the foreign national health and social security weren’t included in the credit, so it was pretty much a wash with me.
