Employers are required by law to lodge a Superannuation guarantee charge statement and are liable for the super guarantee charge (SGC) if they:

• don’t pay the right amount of super guarantee contributions to a complying super fund by the due date
• don’t meet their choice of fund obligations by
  • providing their eligible employees with a choice of super fund, or 
  • requesting a stapled super fund for employees who start on or after 1 November 2021 and are eligible to choose a super fund, but don't.

The SGC is non-deductible against your business income. It has 3 components:

• super guarantee shortfall amounts, including any choice liability and calculated on your employee’s salary or wages (not ordinary time earnings)
• nominal interest on those amounts (currently 10%)
• an administration fee ($20 per employee, per quarter).

To report and rectify the missed payment, lodge a Superannuation guarantee charge statement and pay the SGC to the ATO by the due date.
