Hopefully what that means is that when someone sees a proposal they regard as tax evasion and that could get the proposer into hot water with the tax authorities, they tell the proposer and help prevent them getting into trouble.
I don't know what schemes or clauses you are alluding to here and I'm not sure what they have to do with OP's question.
OP is not correct as I have already stated by posting ...
above. As has been pointed out above and in previous threads here many many times, Revenue have a strict protocol they expect to have observed; any deviation from that protocol is tax evasion.
I have posted my informed honest opinion here, and, as per the posting guidelines have not directed abuse or disrespect at any poster.
