Been a few cases
Had chat with some tax advisers a while ago. Their warning was that uk employment tribunals were now ahead of tax legislation. One might be technically correct under taxation law when contracting in staff but employment law is quite another matter and the courts are now likely to treat a contractor as staff. There were a few tweaks planned to IR35 but the evidence is mounting that many contractors do not full fill the criteria of self employed. Advice was to beware of the benefits of contract staff!
Stand to be corrected but think there will soon come some scrutiny from HMRC. As an aside. A chap I know who joined one of the biggest pilot contractors has been contacted by HMRC who are not happy with him being domiciled in the uk but working through another eu country company, paying tax there etc... Etc... no second prizes for guessing whom I speak of.
Keep the blue side up!
