Does this help From revenue website the chargeable consideration in the case of a new house/apartment with a floor area in excess of 125 sq. metres, acquired by a person for occupation as his/her only or principal place of residence, is the greater of the site value or one quarter of the total value of the house/apartment (less Vat).
My understanding is that it is the chargeable consideration (which is defined in my previous post) that is liable to stamp duty at the relevant rate (see below)
So if the land value is 100K and the building (less vat) costs 400K there is no stamp duty payable.
If the land value is however 200K and the building costs 400K the SD is payable at 3% of 200K
