Also, a US Citizen living and earning an income abroad would have to make a heck of a lot of money over there, over $95K a year, to need to worry about taxes.
No, it's not 95k per year. The family I speak of have had their combined income assessed... meaning the husband and wife. Of the 5 kids, only the youngest has a tax bill... deemed to be S76,000. However, that's still ludicrous as she became an Australian citizen in 1972, just 2 years after the family arrived here.
Now I was born in the UK, but the government there doesn't own my arse and does not expect to collect taxes from me, or any other expatriate, for that matter.
