If subsection 61 - 760(3) applies, the amount of the * tax offset for the income year is the difference between:
(a) what would, under section 61 - 765, have been the amount of the tax offset to which the trust would have been entitled if it had been an individual; and
(b) if * members of the trust are entitled to tax offsets under subsection 61 - 760(2) arising from the same contributions from which the trustee's entitlement arises under subsection 61 - 760(3)--the sum of the amounts, under section 61 - 770, of those tax offsets.
