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 income tax that you are liable to pay because the Commissioner amends your assessment for an income year. 280-100(2)
The liability is for each day in the period: (a) beginning at the start of the day on which income tax under your first assessment for that income year 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. 280-100(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 income 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 Division 5 of the Income Tax Assessment Act 1997 for when the amount of income tax and shortfall interest charge becomes due and payable. That Division also 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.

(i) you are required to lodge your *income tax return for the income year in which the financial benefit is provided or received; or
(d) as a result of paragraph (a) , you are liable to pay an additional amount of income tax for the taxing year.
