The ATO's Small Business Superannuation Clearing House is a free, government-run service that lets eligible employers send a single payment to the ATO, which then distributes contributions to each employee's fund — but the compliance timing rules are more nuanced than many clients realise, and missing the cut-off still attracts the Superannuation Guarantee Charge.
Bookkeepers managing payroll for small employers are frequently the first line of defence against superannuation guarantee (SG) non-compliance. Understanding how the SBSCH works — and where it falls short — is essential for protecting clients from a liability that cannot be claimed as a tax deduction.
Who Qualifies for the SBSCH
The SBSCH is available to employers who meet either of the following criteria:
- Fewer than 19 employees (at the time of making the contribution), OR
- Aggregated annual turnover of less than $10 million
These are two separate qualifying tests — a business with 25 employees but turnover under $10 million can still use the service. The eligibility is assessed at the time of each contribution, not locked in annually. If the business grows to 19 or more employees during the year, it may lose eligibility for that quarter's contribution.
Sole traders and partnerships with no employees cannot use SBSCH (there are no employer contributions to make), but those with employees — including family members paid under a genuine employment arrangement — can enrol.
How to Enrol and Use the SBSCH
Employers access the SBSCH through the ATO's Business Portal or through their registered tax or BAS agent via Online Services for Agents. The employer must:
- Register for the SBSCH through the relevant portal
- Set up employee records with fund details (fund name, USI/ABN, employee member number)
- Verify that all employee funds are registered with the ATO (the SBSCH will reject payments to non-compliant funds)
Payments are made via direct debit or BPAY from the employer's nominated bank account. The ATO processes the payment and distributes to individual funds, typically within five to seven business days of receipt by the ATO, depending on the fund.
The Critical Cut-Off: When SG Compliance Is Achieved
This is the most important point for bookkeepers to communicate to clients. Under the Superannuation Guarantee (Administration) Act 1992, super contributions must be received by the employee's fund by the SG quarterly due date to count as compliant. The SBSCH adds a layer to this timing:
The ATO deems the contribution paid when it is received by the SBSCH — not when it is distributed to the fund.
However, this only holds true if the payment arrives at the SBSCH in time to be distributed before the quarter end. The ATO recommends making payments to the SBSCH at least five business days before the quarterly due date. Given processing times and potential delays, bookkeepers should build in a minimum of seven to ten business days of buffer.
Quarterly due dates (contributions must arrive by):
- Q1 (July–September): 28 October
- Q2 (October–December): 28 January
- Q3 (January–March): 28 April
- Q4 (April–June): 28 July
A payment made to the SBSCH on 27 October for Q1 may not be distributed to all funds before 28 October if there are processing delays. The employer remains technically non-compliant and the SG Charge applies.
When the SGC Applies and Why It Matters
If contributions are late — even by one day — the Superannuation Guarantee Charge becomes payable. The SGC is calculated on the employee's notional earnings base (typically ordinary time earnings, which is broader than base salary), with a nominal interest component and an administration fee. Critically, the SGC is not deductible under section 26-95 of the ITAA 1997, whereas on-time SG contributions are deductible. This makes the SGC significantly more expensive than the headline amount suggests.
Bookkeepers who identify a missed payment should advise the client to lodge a superannuation guarantee charge statement and pay the SGC promptly. Voluntary disclosure and prompt payment reduce penalties. ATO audit activity in the super space has increased materially since the introduction of SuperStream and Single Touch Payroll, both of which give the ATO real-time visibility into payroll and super payment data.
When SBSCH Is Not Enough
There are several scenarios where the SBSCH does not fully address an employer's super obligations:
Defined benefit funds: The SBSCH does not accept contributions to defined benefit funds. Employers with employees in defined benefit arrangements must contribute directly to the fund.
Salary sacrifice arrangements: Employee-initiated salary sacrifice contributions (above the SG minimum) should also be processed through the SBSCH or direct to the fund within the agreed timeframe. The ATO requires that salary sacrifice contributions not be used to reduce the employer's SG obligation below the statutory minimum — the SG is calculated on ordinary time earnings regardless of any salary sacrifice in place.
New employees who haven't nominated a fund: If an employee has not provided a choice of fund, the employer must make contributions to the employee's stapled super fund (obtained from the ATO via the stapled fund lookup in Online Services for Business), or failing that, the employer's default fund. The SBSCH allows payments to any compliant fund, but the employer must first determine the correct fund before submitting.
Quarterly versus monthly pay cycles: Employers on monthly payroll cycles must still meet the quarterly SG due dates. A monthly pay run in June — with super due by 28 July — is often overlooked until the new financial year is underway. Bookkeepers should build a super lodgement calendar tied to the pay cycle, not just the quarterly dates.
Record-Keeping Requirements
Under the Superannuation Guarantee (Administration) Act 1992, employers must retain records for five years that demonstrate when contributions were made, the amount, and the fund to which they were paid. SBSCH payment confirmation receipts and fund distribution reports should be saved to the client's file at each quarter end.
Integrating super contribution records with the STP payroll reporting ensures that the ATO's Single Touch Payroll data and the SBSCH payment records are consistent — any mismatch is a red flag in ATO data-matching algorithms.
