Firstly, the ATO will issue you a Failure To Lodge (FTL) penalty if your tax return isn’t lodged by the due date. This fine is calculated at the rate of one penalty unit for each period of 28 days or part thereof that the document is overdue, up to a maximum of five penalty units. The value of a penalty unit is currently $222, which makes the maximum penalty which can be applied for an individual – $1,110.
The penalty is normally applied automatically but is not normally applied to returns with either a nil result or which generate a refund. Where a penalty is applied, the ATO will sometimes remit it where it’s ‘fair and reasonable to do so,’ such as in the event of natural disaster or serious illness.
