Despite section 276 - 345, an * AMIT does not have an * under or an * over of a particular character for an income year (the base year ) if:
(a) assuming the Commissioner made an assessment of the * trust component of that character on the day on which the document stating the AMIT's * determined trust component of that character for the base year was created; and
(b) assuming the assessment had not been amended at the discovery time mentioned in subsection 276 - 345(2) for the under or over;
section 170 of the Income Tax Assessment Act 1936 would prevent the assessment from being amended to take account of the under or over.
Note: Section 170 of the Income Tax Assessment Act 1936 specifies the usual period within which assessments may be amended.
