He will earn around 60k euro on his contract. If he does not take out the pension that the "gangster" accountants in Dublin tried to sell him he will pay almost 15k euro in tax.
The accountants he tried to use in Dublin calculated his tax payable in Ireland as a UK resident would only be 5k. With cross border relief he might not need to pay any more tax in the UK.
There is a provision in the tax treaty between Ireland and the UK to deal with cross border workers. From what I know it was set up to deal with those people living in Northern Ireland who might be working in the South or the other way around and removes the need to file separate tax returns in both countries.
The proposed accountant's fee was less than what the Brookfield 3 were charging and he said the fee included a UK tax return if needed so long as he did not have other UK income.
This is my point in relation to poor tax advice from the Brookfield 3. If cross border relief could reduce a UK pilot's tax bill and the Brookfield 3 do not use the relief available then the pilot is at a loss and if he wanted could try and sue BRK for the money.
By limiting their service to only dealing with a pilots Irish income the accountancy firm has their ass covered in respect of the bad advice but Brookfield would not necessarily be in the clear as they prevented the contractor from appointing a tax agent in Ireland who would have claimed the maxium relief available.
It might be a bit of a stretch but there are enough hard up solicitors in Ireland and here in the UK who would probably take on the work pro bono.
