Eligible businesses can make super contributions in one transaction using the free, online Small Business Superannuation Clearing House (SBSCH).

The Small Business Superannuation Clearing House (SBSCH) is a free service you can use to make super guarantee (SG) contributions. Eligible businesses are those with 19 or fewer employees or an annual aggregated turnover of less than $10 million.

Your business can pay your SG contributions as a single electronic payment to the SBSCH. If you make super payments by EFT or BPAY using your credit card account, you may be charged a fee by your financial institution.
