It definitely increases the complexity of taxing. Sorry. I know how you feel - I'm an American partnered with (& married to) an Austrian (and we both live in Austria!). However, I'm fairly sure that the UK and US - like every other major country and the US - have an anti-double taxation treaty. Which probably means that you personally will pay taxes only in the country which has the highest rate (clearly your home country). IF - and only if - you get good tax advice up front can you reduce your American taxes by carefully structuring the way you take money out of the company. It's hard to find accountants who are experienced in this. My personal suggestion would be to call Deloit or another big international consultancy. EDIT: Sorry, I got who's UK/who's US backwards. Advice still stands tho. You can definitely form an LLC with a foreigner, even using an online service, it's just that taxes are a bitch. No way around that.
