Income Tax Assessment Act 1997
There is a partial roll-over if you *acquired the original right on or after 20 September 1985 and:
(a) the land to which the new right relates is different in area to the land the subject of the original right because a part (the excised part ) of the land to which the original right related was excised or you relinquished it; and
(b) you received a payment for the expiry or surrender of the original right.
The payment can include giving property: see section 103-5 .
Section 124-600 sets out the effect on your cost base.124-590(2)
There is no roll-over for the excised part. The *cost base of the excised part is so much of the *cost base of the relevant *Crown lease as is attributable to the excised part.
Its *reduced cost base is worked out similarly.
You may make a capital gain or loss on the excised part because of CGT event C2.
