The Australian Business Number (ABN) for a superannuation fund is a vital identifier for businesses handling employee superannuation contributions in Australia. For employers, grasping the importance of a super fund ABN ensures accurate payments and compliance with Australian Taxation Office (ATO) and Fair Work regulations.
This overview details what a super fund ABN is, its significance, methods to find it, and the compliance requirements for Australian businesses.
A super fund ABN is a unique 11-digit code assigned to a superannuation fund by the Australian Business Register (ABR). It identifies the fund for tax and regulatory purposes, used when employers process super contributions, report via Single Touch Payroll (STP), or manage payroll. Each super fund, such as AustralianSuper, Rest, or Hostplus, has a distinct ABN, separate from an employer’s or employee’s ABN.
In Australia, employers are required to contribute 11.5% of an employee’s wages to their chosen super fund, as mandated by the ATO. The super fund ABN ensures contributions are allocated correctly to the intended fund and account, preventing errors that could result in penalties or lost super.
Employees provide super fund details, including the ABN, upon starting employment through a Superannuation Standard Choice Form.
The ATO’s Super Fund Lookup tool provides ABNs for all registered super funds.
Reach out to the super fund for their ABN.
The ATO’s myGov platform or Business Portal may include super fund ABNs for employee contributions.
Employers must use the correct super fund ABN to fulfill ATO and Fair Work requirements:
For example, a Canberra business uses Hostplus’s ABN (68 657 495 890) to pay $1,500 in quarterly super for an employee, ensuring STP compliance.
A Queensland business with four employees sets up super contributions:

Check their Superannuation Standard Choice Form, use Super Fund Lookup at https://superfundlookup.gov.au/, or contact the fund.
It ensures accurate super contributions and STP compliance, avoiding ATO penalties.
No, you must use the super fund’s ABN, not your business ABN.
Contributions may be misallocated, risking penalties and employee disputes.
