Thank you for your very helpful answer.
-Is it only for the past 6 years that need to be filed (so would it be from 2009 or 2010)?
-I will look for a UK firm to assist with this but I wondered if you are able to recommend any firms if you have any dealings with anyone in the UK?
Thank you, ***** ***** found you very helpful and knowledgeable. I have more questions regarding other aspects of US tax if I were to set up a UK business but trade in the US in the future so will come back to you on that when I am ready.
Thanks again for your help.
