I'll start this post with the following comment: I can not offer any assistance. Therefore, unfortunately, my comments will be general.
As I understand, informational Form 8621 must be filed
each and every year one holds a PFIC. The intention to hold the PFIC for an extended period is of no consequence. As you have likely discovered, if you are doing
Streamlined, that indicates doing 8621 for 3 years, plus the current year. It's also my understanding that some computations must be made on a daily basis (I could be wrong). I'm sure you've noticed that the time estimated by the IRS for completing the form for one PFIC, combining recordkeeping and preparation only, is 37 hours. An additional 11 hours is recommended for 'learning about the law or the form'.
Both Congress and the IRS are aware of the extreme difficulty of completing this form.
It is intentional. If the form is not filed yearly, its' extreme punitive nature and penalties may offset (by up to 100%) any gain made on the investment.
Again, this is intentional. Investments in any foreign PFIC are highly discouraged for anyone
resident in the US. As a US Citizen, you are automatically considered
resident in the US for tax purposes (and I believe you are now aware of this).
The only recorded incidents in online expat forums, of which I am aware, of someone completing 8621 without professional assistance speak of the individual preparing special (and complicated, time consuming) spreadsheets in order to comply. Unless online tax packages such as TurboTax or TaxAct have changed, the assumption must be that the really difficult part, the calculations, must still be completed by the individual. Perhaps someone can comment.
You'll have to decide whether your account with HL counts as only 1 PFIC, or whether each element becomes a separate PFIC. Again, I may be wrong, but the latter seems the most likely.
Aside from the obvious considerations, I would suggest it may be imperative to give sufficient thought to; 1) consider the implications of completing 8621 yearly if you wish to remain US tax compliant, 2) consider discarding any investment which could be considered a PFIC for the future if you wish to remain US tax compliant, 3) consider renouncing US citizenship (but you would then be required to file
5 years of past returns).
I'm sorry if this comes across as brutal. You do have my sympathies, but it might be helpful to hear the raw 'truths' from someone else if only to confirm the options you have (or, it may not be helpful
