Hmm, don't know why this has been posted on a public forum, but the fact is that everybody concerned is quite entitled to pay their accountant to deal with the matter.
An ex colleague and friend of mine was extremely pi**ed of to receive an unsolicited phone call from John Moore last week asking "what did he know?" about this issue. It disappoints me that Balpa see fit to phone a pilot rather than consult their own experts, and gives the impression that they want to take the credit for somebody else's hard work.
It's very simple - if you want to avoid possible fines and investigations then get your own tax adviser to look into it - if you want to wait for Balpa to sort it out you could be waiting a long time!
