SuperStream: the data and payment standard for super contributions

What SuperStream is

SuperStream is the data and payment standard for superannuation contributions and rollovers under the Superannuation Industry (Supervision) Act 1993. It establishes a consistent method for transmitting information related to superannuation.

The standard requires contributions and member data to be sent electronically in a standardised format. This approach supports straight-through processing by super funds, reducing manual intervention and improving efficiency. Employers needing to check their Payday Super readiness should familiarise themselves with SuperStream requirements.

SuperStream applies to employers, super funds, and self-managed super funds (SMSFs) receiving employer or rollover contributions.

When it commenced

SuperStream became mandatory for medium and large employers, defined as those with 20 or more employees, from 1 July 2014. This marked the initial phase of its implementation.

The rollout continued with smaller employers. SuperStream became mandatory for small employers, those with fewer than 20 employees, from 1 July 2015. Some limited transitional relief was available for these employers until 28 October 2016.

The functionality to process rollovers, which involves transferring superannuation balances between funds and to Self-Managed Superannuation Funds (SMSFs), was introduced in stages between 2014 and 2021.

What employers must do

Employers must send contribution data and the matching payment in the SuperStream format to each employee's super fund. This applies regardless of the size of the business.

To comply, employers must use a SuperStream-compliant solution. Common options include payroll software with built-in SuperStream functionality or a clearing house. Eligible small employers may use the ATO's Small Business Superannuation Clearing House.

Employers are required to collect each new employee's super fund and member account details and integrate this information with the SuperStream data feed.

Payday Super from 1 July 2026

From 1 July 2026, new reforms will require superannuation contributions to reach an employee’s nominated fund within seven business days of each pay event. This change affects the timing of superannuation payments and data transmission.

SuperStream will continue to be the technical standard used to deliver these payments and associated data. Employers will utilise SuperStream to transmit the required information to clearing houses or directly to the superannuation fund.

To ensure compliance and avoid potential Super Guarantee Charge exposure, employers are advised to test their pay-event timing, clearing-house cut-offs, and SuperStream throughput well in advance of the reforms commencing.
