General interest charge (GIC) rates

When GIC applies

We may apply general interest charge (GIC) if an amount of tax or some other liability remains unpaid after the date it should have been paid. This includes where:

there is a tax shortfall because of an amendment or correction
an instalment of tax is underestimated
a return is lodged late.

The GIC is updated quarterly with rates for the next quarter generally announced 2 weeks before the start of that quarter.

How GIC is calculated

Section 8AAD of the Taxation Administration Act 1953 specifies how the rate of the charge is calculated. To work out the daily rate, divide this rate by the number of days in a calendar year.
