If you know how you can get yourself an exemption from Irish and UK tax. The problem most FR guys have is that the accountants that they have been forced to appoint wont bother to do it as it would mean more work for them.
If you are with one of these and stuck as a director of an Irish company together with three other goons who you have never met then find a "proper" Irish tax advisor who will get your money back for you and get your tax return filed in Italy or wherever.
We all know that we had to put up with the 3% accountants (or mortgage broker as the is the case with Mcnamara)or loose our jobs. If you still want to minimise your tax liability you will still need a proper accountant.
