I'm a US citizen (I have no other citizenships) who's been living in Ukraine for several years. I've passed the 330 days out of US test. I have a permanent Ukrainian residency permit, and I'm married to a local. In the past I've kept paying US taxes as if I was a full resident, but I've heard local Ukrainian taxes can be a better deal. I work remotely (and lead a local team) for a US company that withholds tax from the state I used to live in (I use a relative's address).
Can I claim the Foreign Earned Income Exclusion? When I figure out how to pay local tax here, what should I be prepared to show the IRS in case they ask?
