A growing number of Americans abroad are renouncing their US citizenship, citing the burden of US tax filing requirements and the complexity of maintaining compliance from overseas. US citizens are required to file taxes globally on worldwide income, even if they claim the Foreign Earned Income Exclusion (FEIE) or live in a country with which the US has a totalization agreement. Beyond taxes, the cost of annual filings, FBAR (Foreign Bank Account Report) obligations, and the administrative weight of US financial reporting have pushed some expats to formally sever ties.
