Any transfer of the whole property in goods is a supply of goods, but the transfer of any undivided share of the property or of the possession of goods is a supply of services (VATA 1994, Sch. 4, para. 1(1)).
On the other hand, there is a supply of goods if possession of goods is transferred under an agreement for the sale of the goods or under an agreement which expressly contemplates that the property also will pass at a future date, determined by, or ascertainable from, the agreement which is, at the latest, when the goods are fully paid for (Sch. 4, para. 1(2)).
The importance of these provisions lies in the tax point rules.
