I was born in Canada to US citizen parents: thus I was born a Canadian-US dual citizen. I have complied with all US and Canadian tax laws, including filling my FBARs and, for my 2011 taxes, the new Form 8893. (My total bank accounts and investment accounts come to $700K.) On May 15, I renounced my US citizenship. I understand that, for 2012, I must file as a dual-status alien: Form 1040NR, with Form 1040 up to May 14 filed as a schedule. Here are my questions: (1) Must I file Form 8893 for 2012? If yes, must I include specified assets acquired after renunciation? (2) Must I file an FBAR for 2012? If yes, must my FBAR include any accounts opened after renunciation? (3) If I open a grantor trust (such as a Canadian Tax-Free Savings Account) after renunciation, must I file Form 3520? Thanks.
