What with the Brexit completely murdering UK stocks right now, and having taken to heart the motto "buy when there's blood in the streets", I was thinking of investing some money in the UK, via ETF. My main worry (other than obviously the worry that it won't recover, but I think long-term) is that it will complicate my tax situation too much (I've always filed taxes myself using Turbotax, and would prefer not to have to pay significantly more money next year to hire a professional). For some reason, I can find loads of information on implications of holding US stocks as a UK citizen, but hardly anything on the opposite, being an American citizen holding UK stocks.
From what I can tell, there is an agreement between the two countries such that dividends aren't taxed by the UK, is that still accurate? And does that imply that no special tax forms would be required, or just that nothing would happen as a result of filing them (if the latter, how well do tax software handle them?) And what about when I eventually liquidate some of it - how complicated will that make my life, tax-wise?
