There is no stamp duty on the sale of new residential property where the purchaser is an owner-occupier and the house is not greater than 125 square metres. The purchaser must certify to the Revenue Commissioners that he/she intends to occupy the property as his or her private residence and must not derive any rent for the use of the house, for a period of five years or until the house is sold. This stamp duty exemption for new houses is available to all owner-occupier purchasers, including first time owner occupier buyers, irrespective of the consideration paid.
