It’s amazing that a lot of people who fiddle their tax need to brag about it; especially in the pub. It gives them an auro of cleverness to show what they can get away with. The Tax Inspectorate are well aware of such bravado and many a dodger has been caught from an overheard conversation. There are things going on behind the scenes of which we know nothing. The Revenue will never stop fraud completely it but it does act as a warning to others.
