- Quarter 2 SG contributions are to be received by the superfund by this date – you need to allow sufficient time for SG payments to reach and be processed by your superfund, especially if using a SG clearing house.
 - If you don't pay the SG contributions for quarter 2 in full and by this date, you must pay the super guarantee charge (SGC) and lodge a SGC statement with us by 28 February.
 
 
It's important to note, SGC is more than the SG you would have normally paid and is not tax deductible.
