INCOME TAX ASSESSMENT ACT 1936
Section 159Q applies in relation to an indexing year of income as if each indexable amount were replaced by the amount calculated using the formula:
|Previous indexable amount × Indexation factor|
Previous indexable amount is the indexable amount concerned for the previous year of income;
Indexation factor is the indexation factor for the indexing year of income.
Where, apart from this subsection, an amount calculated under subsection (1) would be an amount of dollars and cents:
(a) if the number of cents is less than 50 - the amount shall be rounded down to the nearest whole dollar; and
(b) in any other case - the amount shall be rounded up to the nearest whole dollar. 159HA(3)
The indexation factor for an indexing year of income is the number (calculated to 3 decimal places) ascertained by dividing the sum of the index numbers for the quarters of the 12 month period ending on 31 March immediately before the indexing year of income by the sum of the index numbers for the quarters of the preceding 12 month period ending on 31 March. 159HA(4)
If the factor ascertained under subsection (3) in relation to an indexing year of income would, if it were calculated to 4 decimal places, end with a number greater than 4, the factor ascertained under that subsection in relation to that indexing year of income shall be taken to be the factor calculated to 3 decimal places and increased by 0.001. 159HA(5)
Subject to subsection (6), if at any time, whether before or after the commencement of this section, the Australian Statistician has published or publishes an index number in respect of a quarter in substitution for an index number previously published by the Australian Statistician in respect of that quarter, the publication of the later index number shall be disregarded for the purposes of this section. 159HA(6)
If at any time, whether before or after the commencement of this section, the Australian Statistician has changed or changes the index reference period for the Consumer Price Index, then, for the purposes of the application of this section after the change took place or takes place, regard shall be had only to the index numbers published in terms of the new index reference period.
