(1) You are liable to pay a penalty, for a * GST instalment quarter of an * instalment tax period applying to you, if you have a * varied instalment amount for the GST instalment quarter, and:
(a) if the instalment tax period is a * financial year--the sum of your * GST instalments for all the GST instalment quarters of the instalment tax period is less than 85% of your * annual GST liability for the instalment tax period; or
(b) if the instalment tax period is only part of a financial year--the sum of:
(i) your * GST instalments for all the GST instalment quarters of the instalment tax period; and
(ii) your * early net amounts for the financial year (subtracting any of those amounts that are less than zero);
is less than 85% of your annual GST liability for the instalment tax period.
(2) The amount of the penalty, for a particular day, is worked out by applying the * general interest charge:
(a) for each day in the period in section 162 - 190; and
(b) in the way set out in subsection 8AAC(4) of the Taxation Administration Act 1953 ;
to your * GST instalment shortfall, under this section, for the * GST instalment quarter.
(3) Your GST instalment shortfall , under this section, for the * GST instalment quarter is the amount worked out as follows:
where:
"GST already payable" is the sum of:
(a) the * varied instalment amount; and
(b) all your other * GST instalments (if any) for earlier * GST instalment quarters of the * instalment tax period in question; and
(c) if the instalment tax period is only part of a * financial year--your * early net amounts for the financial year (subtracting any of those amounts that are less than zero).
(4) However, if:
(a) the * GST instalment quarter is not the first GST instalment quarter of the * instalment tax period in question; and
(b) you are liable for one or more penalties under this section in relation to any of the earlier GST instalment quarters of the instalment tax period;
then:
(c) your GST instalment shortfall , under this section, for the * GST instalment quarter is the difference between:
