REMINDER
If you do not pay an employee's minimum superannuation guarantee amount on time and to the right fund, you must pay the superannuation guarantee charge (SGC). You must also lodge an SGC statement with the ATO.
The SGC is more than the super you would have otherwise paid to the employee's fund and is not tax deductible.
