I want to add a UK-specific viewpoint for anyone with a British business who's wondering if a US entity is a necessity for dealing with US corporations. I run a service-oriented business with 10 employees in the UK and most of our income is from US-based corporations. Externally we work entirely in USD. Once we determined our tax and legal positions, we've not encountered any problems with payments, wires, forms (W-8BENI is accepted in place of W-9s), or taxes, and our customer roster is a couple hundred tech companies - ranging from F500s with arcane vendor account requirements, through to mid range companies, startups, and small ISVs. Trade between the UK and US is common and, depending on what you are trading, has a low amount of friction due to the UK's relatively open nature and low level of bureaucracy on matters of banking, international trade and taxation. (If you sell physical items, need to take on US-based staff, start a US office, are a low margin business that couldn't take exposure to exchange rates or cross-border tax volatility, or need to appeal to US investors, disregard the above and get a US entity! :-))
