This calculator does not constitute legal advice. Legal advice is dependent upon the specific circumstances of each situation. This calculator only returns the maximum potential penalty under the tax law as at April 2017. It does not take into account the case law or the exercise of a Judge or Magistrate’s discretion in determining the applicable penalty. 

This calculator does not calculate the maximum potential penalty where the Commissioner of Taxation has elected to treat an offence otherwise than as a prescribed offence. This is because it is not very common for the Commissioner to make this election for non-lodgment charges. If this election was made, then the maximum penalty will be higher than the amount calculated by this calculator, and there is a possibility of jail time (up to 12 months).
