Indexation of the cost base

Last updated 3 March 2016

If a CGT event happened in relation to a CGT asset you acquired before 11.45am (by legal time in the ACT) on 21 September 1999 and owned for at least 12 months, you may be able to use either the indexation method or the discount method to calculate your capital gain.

If you use the indexation method, some of the cost base expenditure you incurred up to 11.45am (by legal time in the ACT) on 21 September 1999 may be indexed to account for inflation up to the September 1999 quarter. Only expenditure incurred before 11.45am (by legal time in the ACT) on 21 September 1999 may be indexed because changes to the law mean indexation was frozen at that date. Refer to chapter 2 for more information on the indexation and discount methods.
