Income Tax (Transitional Provisions) Act 1997

Section 104‑70 of the Income Tax Assessment Act 1997 applies for the purpose of working out the cost base of a unit or an interest you own in a trust if these conditions are satisfied:

CGT event E4 happens in relation to the unit; and

you were taken to have disposed of the unit or interest under former section 160ZM of the Income Tax Assessment Act 1936 (the former equivalent of CGT event E4) because of a payment made by the trustee before 18 December 1986; and

some or all of the payment (the non‑assessable part) was not included in your assessable income; and

some or all of the non‑assessable part (the attributable part) was attributable to a deduction under former Division 10C or 10D of Part III of the Income Tax Assessment Act 1936 (about capital works).

The cost base of the unit or interest is also reduced by the attributable part.

Subsection 104‑70(5) of the Income Tax Assessment Act 1997 also reduces the cost base and reduced cost base of a unit or interest to nil if an amount was taken into account as a capital gain for the unit or interest under former section 160ZM of the Income Tax Assessment Act 1936.
