Currently ryanair is forcing pilots to have irish ltds, others used to get away with offshore accounts and living under the radar for a lousy pilot salary - scared to buy a car in their name.
Not defending Ryanair and their employment model.
But, some pilots are their own worst enemy. Having companies in Malta, Dubai or Guernsey while staying under radar in Europe without a permanent address then you deserve to be shot down. Paying hardly any tax on a Brookfield pay rate can't be said is a lousy pilot salary.
