The are a couple of things I don't understand, the renunciation and coming clean with the IRS seem to be two different things. Right? Or do you still have to spend a small fortune filling all sorts of things only to find out that you still don't owe any money to the IRS before you can renounce?
And if you don't renounce then the IRS can still come after you till the time stipulated by statute of limitations lapses, right? What's that? 10 years?
All IMHO. I’ve just been reviewing your original thread,
RE: Accidental American panic.
If I understand correctly, you were born in the US to non-US / non-British parents. Your family left the US to return to the family country, and later you and the family moved to the UK where you became a naturalised British citizen. Is this correct? If so, it may be important.
The act of (relinquishing/renouncing) is an exercise technically separate from the exercise of being compliant with US tax obligations. You may (r/r) by filing the forms, going to the US Embassy , and completing either the (r or r). For these actions, your compliance with US tax has nothing to do with (r/r). If you so desire, you may never, ever, file anything to do with US tax obligations,
BUT,Given your background, if you do not comply with US tax obligations, you will become a “covered expatriate”. Technically, the US tax authorities may hound you up to, and after, your eventual death. The US Congress continues to display its eagerness to find ways to make life Hell for covered expatriates.
Is this a problem for you?
How long is a piece of string? What turns will your life take in the future? What legislation will be passed by the US and will the UK submit to US dictates (like it has for FATCA)? Or, will (r/r) be the last you ever hear about US tax obligations and will the US forget all about you? Might you find it easy to avoid the US forever?
There are arguments for both, and there are no answers other than you could pay up now, get a CLN, and know (for now) you’re free. Other than having a CLN, nothing is guaranteed, and some speculate even that isn’t certain. There are no simple answers.
As long as you are a US citizen (or a covered expatriate), you will have US tax obligations. Technically, the IRS may come after you for any year you were required to have filed a 1040, but didn't.
