Whether a service is “related to land” is important because there are distinct rules for this type of supply compared to the General Rule. The place of supply (POS) of land related services is where the land is located, regardless of where the supplier or recipient belong.
The rule applies only to services which relate directly to a specific site of land. This means a service where the land is a central and essential part of the service or where the service is intended to legally or physically alter a property.
It does not apply if a supply of services has only an indirect connection with land, or if the land related service is only an incidental component of a more comprehensive supply of services.
