Rate on purchase up to €254000 is 4%, and from €254000 to €317,500 it is 5%. For eg house being bought for €270000.00. But there are contents worth 20,000 going with the house. The stamp duty will be calculated on €250000 ( i.e €270,000- €20000) @ 5% ( the higher rate). The contents must be genuinely worth €20,000.00. As to who values them, sometimes the auctioneer involved will, or you and the vendor could draw up a list of contents and do it yourselves. Nothing else can be deducted to arrive at the stamp duty amount, unless it is a brand new build, in which case, there is a possibility of a different calculation and the VAT being taken off before the calculation. Is that the case?
