U.S. taxpayers who live overseas may still have a Foreign Bank Account Report (FBAR) and form 8938 filing report for their foreign financial accounts. In general, your FBAR obligations will not be impacted by the fact that you live overseas. If you are a U.S. person and your aggregate account balance of foreign accounts exceeded $10,000 during the year, you must file an FBAR, regardless of where you live.
Your Foreign Account Tax Compliance Act (FATCA) obligations using form 8938 require a bit more discussion. Whether you need to file a form 8938 could be impacted by country of residency because there are different threshold amounts depending on whether you live in the U.S. or abroad.
