My officials will correct me if I have this wrong, but using the Deputy's example, if that home is worth €300,000 but had been valued at €100,000 at point of purchase by the owner, the tax would be applied on the difference between the €100,000 and the €300,000, that is, on the €200,000. Actually, as opposed to me saying what has just been said to me by my officials and risking getting a point of detail wrong, I would like to invite one of them to give the Deputy the accurate answer in private session.
