I’m a US citizen who occasionally works as a US tax preparer. I’ve also lived outside the US for about 16 of the last 25 years. In addition to what Desert Nomad said so well, I would add:
The basic rule of thumb is that if your daughter lives outside the US for 330 days/year, or is a “bona-fide resident” of another country, she is exempt from tax on the first $85,700 of her foreign earnings. (The earnings can actually be paid in the US, but must be earned overseas.) If she is a bona fide resident who is there for a part of a year (not uncommon, I’m on two year contract now that stretches across three years), she is only entitled to exempt that portion of her income for the year in proportion to the time she spent overseas.
From the US Tax point of view, I am a bona-fide resident in this tiny and exquisitely lovely country for one reason. I have a residence permit and a work permit from the Government. That’s what makes me a bona-fide overseas resident for tax purposes.
Absent that, she’s got to do the full 330 daze to get the credit, with one exception. If she is taxed overseas on her income in one or more countries, she can in most cases offset that against her US taxes. If that’s the case, then get the tax man’s name from Desert Nomad.
The underlying theory is that income is only taxed once. If it is made overseas and taxed overseas, in most cases the home country reduces taxes accordingly.
I use TurboTax (Mac version 'cause that’s what I’m on, there’s a PC version as well) tax software to prepare my own and others taxes. It asks you all of the questions to determine the circumstances and fills out and prints all of the forms, takes all the mystery out of it, checks for errors, you or your daughter could do it.
I would also be very curious about the exact details of her employment. It seems to me that someone in Britain hiring Americans to work in Croatia is not very visible on anyone’s radar … Workers Compensation? Oh, no, none for me thanks, they’re overseas “Independent Contractors” from Britain’s point of view, and they’re not working in Britain … or are they (working in Britain)?
My guess is that she won’t really be on anyone’s books, that the whole deal will go on in that lovely gray area that is in between countries and businesses, the mysterious foggy Eurozone, where nobody really either lives or works in one country, for goodness sake, that’s so 20th century …
I have a seventeen year old daughter. If she were going on such a quest, I’d want her to have some kind of workmen’s compensation insurance, I’ve seen the traffic in Rome and Paris … but hey, what do I know? I’m just the dad.
