GIC Calculator - Hartigan Law

This calculator will help you to work out roughly how much General Interest Charge you will pay on your tax debt if you pay it after the due date.

It is designed to show you how much GIC you will pay on tax debts that are due in the future. It is not designed to calculate how much GIC is payable on a debt that is already overdue.

The calculator uses the rate of 7.10% per annum (the GIC rate as at 1 July 2020), compounded daily.
