USI & ABN details for employers

CareSuper’s Unique Superannuation Identifier (USI) is MTA0100AU. The USI is used in SuperStream and employer payroll/clearinghouse systems to uniquely identify the super product to which contributions should be sent.

You’ll need to provide that ABN when:

• setting up contributions for new employees (so their super goes to the correct fund)
• updating payroll or clearing house systems (so those systems recognise CareSuper properly) 
• consolidating super contributions or switching funds (so the contributions are directed to the correct fund)

Here’s how employers can submit super contributions to CareSuper using the USI: 

1. Use a SuperStream-compliant method (payroll system or clearing house) 

• You’ll need to ensure the fund name, USI, and ABN are entered correctly in your system. 

2. Via CareSuper’s QuickSuper clearing house (if you prefer a dedicated portal) 

• Register as a CareSuper employer for QuickSuper (which is free).

• Once registered, you can upload a contribution file (bulk) or enter contributions manually online. 

• QuickSuper will give you remittance advice and transmit the payment instructions to CareSuper so your contributions align with the USI/ABN settings. 

3. Use your existing clearing house or payroll system

• If your current system is SuperStream-compatible, you can send contributions to CareSuper by entering the correct USI (MTA0100AU) and fund name in your files.   

• The system will then route the contributions appropriately using those identifiers.

4. Complete any required registration or set-up steps 

• If using QuickSuper, you may need to fill out an application or contact CareSuper to activate it for your business. 

• Ensure your payroll or clearing house systems are updated with CareSuper’s current USI & ABN to avoid misrouting or rejections.
