This e-Tax Guide1 explains and provides examples of transactions that are
regarded as neither a supply of goods nor services and hence are not subject
to GST.
You should read this guide if you are:
(a) Transferring your business as a going concern; or
(b) Transferring or assigning the title to the goods comprised in a hire
purchase agreement when you assign your right to receive payments
(as a financier) under the agreement to another financier; or
(c) Transferring qualifying income tax deductions to another company
belonging to the same group of companies as you.
