Commonwealth Consolidated Acts Commonwealth Consolidated ActsGeneral rule
(1) In working out whether you have made a capital gain or a capital loss from a CGT event that happens in relation to a CGT asset in the 1998 - 99 income year or a later income year, you use only the provisions of Parts 3 - 1 and 3 - 3 of the Income Tax Assessment Act 1997 (or a provision of an Act that modifies the operation of those Parts) unless a provision of this Part or Part 3 - 3 of this Act also requires you to use another provision.
Note 1: This means that, for example, in working out your cost base of the asset, you will apply the new law to circumstances that occurred before the 1998 - 99 income year (except where this Act requires you to use another provision).
Note 2: In most cases, the other provision is a provision of this Act. However, in some cases, other provisions may be relevant (for example, provisions of the Income Tax Assessment Act 1936 ).
Note 3: Part X of the Income Tax Assessment Act 1936 includes provisions that modify the operation of Parts 3 - 1 and 3 - 3 of the Income Tax Assessment Act 1997 .
Roll - overs
(2) If:
(a) an entity acquired a CGT asset before the start of the 1998 - 99 income year as part of a transaction or event or series of transactions or events in respect of which there was a roll - over under the Income Tax Assessment Act 1936 ; and
(b) the entity owned the asset just before the start of that income year; and
(c) a CGT event happens in relation to the asset in that income year or a later one;
the provisions of Parts 3 - 1 and 3 - 3 of the Income Tax Assessment Act 1997 apply to the asset from the time when the roll - over happened except that the first element of the cost base and reduced cost base of the asset (when the roll - over happened) is the amount the entity is taken to have paid as consideration in respect of the acquisition of the asset under the relevant provision of the Income Tax Assessment Act 1936.
