I've heard it all. A lesson on the morality of paying in full ones tax liability from a former Ryanair pilot. Oh the irony.
I will bet you 40-odd pennies in the pound, plus 2 sets of NI, PRSI, plus any other "bailing out the Cetic-flipping-tiger" fee you can think of, that this former Ryanair pilot paid more tax than you, so let's nip that one.
I left, (and am happier and better off) and I know loads of others who have done the same, or are on the way.
Which with beautiful symmetry, brings us back to the thread topic.
Edit: beaten to it by the two posts above!
