General interest charge (GIC) rates

When GIC applies

On 1 July 1999, the penalty arrangements for late payment and other obligations were streamlined with the introduction of a uniform tax deductible general interest charge (GIC). The GIC replaced a complex system of interest and penalties we imposed for late payments.

From 1 July 1999 to 30 June 2000, the GIC was based on the relevant 13-week Treasury Note rate plus 8 percentage points. In June 2000, the Australian Office of Financial Management announced that fixed term Treasury Notes, including the 13-week Treasury Note, would no longer be issued. Due to this, the GIC rate of 13.86% remained fixed from June 2000 until the new legislative basis, the 90-day Bank Accepted Bill rate and a reduced uplift factor of 7% was adopted from 1 July 2001.

During the 2000 financial year, the GIC daily compounding rate only applied to pay as you earn, the prescribed payment system, the reportable payment system and sales tax with a simple interest rate applying to other taxes. However, the GIC compounding rate now extends to most taxes, including:

  • income tax
  • fringe benefits tax
  • goods and services tax
  • pay as you go.

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.
