(1) Despite sections 48-45 and 48-50, a * GST group is treated as a single entity, and not as a number of entities corresponding to the * members of the GST group, for the purposes of working out:
(a) the amounts of any input tax credits to which the * representative member is entitled; and
(b) whether the representative member has any * adjustments; and
(c) the amounts of any such adjustments.
(a) while you were not a * member of any * GST group, you acquired or imported a thing; and
(b) you become a member of a GST group at a time when you still hold the thing;
then, when the * representative member of the GST group applies section 129-40 for the first time after you became a member of the GST group, the * intended or former application of the thing is the extent of * creditable purpose last used to work out:
(c) the amount of the input tax credit to which you were entitled for the acquisition or importation; or
(d) the amount of any * adjustment you had under Division 129 in relation to the thing;
as the case requires.
(2) This section has effect despite section 11-25 (which is about the amount of input tax credits) and section 17-10 (which is about the effect of adjustments on net amounts).
