Part F – A “U.S. citizen” cannot use a “tax treaty tie breaker” to break U.S. “tax residence”. How then does a “U.S. citizen” cease to be a “U.S. tax resident”? I am a U.S. citizen. I do not live in the United States. I live in Canada. I am a Canadian citizen. How do I stop being subject to the all of the FBARand other reporting rules, tax rules (including PFIC), life restrictionsand inability to effectively invest and plan for retirement imposed by the Internal Revenue Code? Yourelinquish U.S. citizenship. Please note that a “renunciation” is one form of “relinquishment”. In general, the date of relinquishment of U.S. citizenship is more important than the form of relinquishment of U.S. citizenship. A Certificate of Loss of Nationality (“CLN”) may or may not (depending on the date of relinquishment) be necessary to cease to be subject to U.S. taxation. In simple terms, where do I get information about the process of renouncing U.S. citizenship? You can start here. What are the tax consequences of relinquishing or renouncing U.S. citizenship? The Internal Revenue Code describes the tax consequences of relinquishing/renouncing U.S. citizenship. See Internal Revenue Code S. 877A (the “Exit Tax” rules).
