Taxation Administration Act 1953
Note: See section 3AA .Chapter 4 - Generic assessment, collection and recovery rules
You are liable to pay *shortfall interest charge on an additional amount of *petroleum resource rent tax that you are liable to pay because the Commissioner amends your assessment under the Petroleum Resource Rent Tax Assessment Act 1987 for a year of tax (within the meaning of that Act). 280-102(2)
The liability is for each day in the period:
(a) beginning at the start of the day on which *petroleum resource rent tax under your first assessment for that year of tax was due to be paid, or would have been due to be paid if there had been any; and
(b) ending at the end of the day before the day on which the Commissioner gave you notice of the amended assessment. 280-102(3)
However, if an amended assessment reinstates all or part of a liability in relation to a particular that had been reduced by an earlier amended assessment, the period for the reinstated liability begins at the start of the day on which *petroleum resource rent tax under the earlier amended assessment was due to be paid, or would have been due to be paid if there had been any.
See section 82 of the Petroleum Resource Rent Tax Assessment Act 1987 for when the amount of petroleum resource rent tax and shortfall interest charge becomes due and payable. Section 85 of that Act provides for general interest charge on any part of the additional amount (plus any shortfall interest charge) that remains unpaid after the additional amount is due and payable.
