I am about to work for an American company while based in the UK. They tell me they'll tax at 30% unless I apply for a US tax ID. Does anyone have any advice on this? How much tax wld I have deducted WITH a US tax ID? Can I claim back the extra tax through my UK tax return?
I cannot imagine I'll earn more than about $15,000 per year. This is as a freelancer. I will be doing other freelance work for UK companies (which may come to about £5000, max). So we're really not talking big bucks so I'm keen not to lose money for lack of knowledge.
I am based in England and have a UK tax ID.
Thanks so much for any help!
