Payday Super: Updated Industry Timeline and What Happens Next
From 1 July 2026, employers will be required to pay Superannuation Guarantee (SG) contributions at the same time as salary and wages.
The Payday Super reform represents one of the most significant, whole-of-ecosystem changes the superannuation industry has seen in more than a decade. With less than 5 months to go, the period between now and go-live will determine whether the reform delivers on its promise of closing the unpaid super gap and improving transparency for workers.
As the governing body responsible for oversight of the Superannuation Transaction Network (STN), the Gateway Network Governance Body (GNGB) has mapped the critical milestones, risks and operational priorities the industry must navigate to reach 1 July 2026 in a safe and coordinated way.
Timeline and key milestones
September – December 2025: Final legislation and industry alignment
This phase marks the shift from policy to delivery.
Key milestones include:
- Final Payday Super legislation is passed (4 November 2025) and receives Royal Assent (6 November 2025).
- SuperStream data and payment standards are finalised.
- Payroll providers, funds, clearing houses and gateway operators commence full software builds.
- Super funds and administrators refine faster member validation and error-handling processes.
- Employers begin data clean-up, correcting errors and reviewing payroll processes for pay-day frequency and cash-flow impact.
- The ATO Small Business Superannuation Clearing House (SBSCH) closes to new customers on 1 October 2025.
- The ATO consults on its Practical Compliance Guide for the first year of Payday Super (1 July 2026 – 30 June 2027).
- Single Touch Payroll (STP) changes — including the introduction of Qualifying Earnings (QE) — are incorporated into systems.
- Industry education accelerates across employers, payroll providers and funds.
Key risks
- Delays to detailed regulations, technical artefacts or remaining legislation (including stapling changes)
- Unclear or late technical specifications
- Small businesses falling behind in preparation
January – March 2026: Testing and early rollouts
This is where theory meets reality.
During this quarter:
- Full end-to-end testing environments open — from payroll through to super funds.

- Funds, clearing houses and service providers integrate and test faster payment workflows with banks.
- Large employers commence pilot programs.
- Industry rehearses error-handling under compressed timelines.
- The ATO releases final compliance guidance, including SG Charge treatment.
Key risks
- Organisations not ready to test
- volume estimates inaccurate

- Unresolved error-handling pathways
April – June 2026: Cut-over readiness
This is the industry’s final readiness sprint.
Critical actions include:
- Final end-to-end testing of all SuperStream changes for funds ready for 1 July
- Completion of technical cut-over plans
- New error-messaging frameworks go live between 8 May and 11 June 2026
- Communication campaigns to employees and members
- SBSCH wind-down — employers to access and save historical data. No employer access or contributions after 11:59pm, 30 June 2026
- All participants complete readiness checklists
Key risks
- Late readiness failures
- Communication gaps
- Testing issues taking longer to resolve
1 July 2026: Payday Super goes live
From this date:
- Employers must pay SG on every payday
- Funds enforce faster allocation and rejection timeframes

Conclusion
Payday Super is one of the most complex operational reforms the superannuation system has ever faced.
With 1 July 2026 fixed, the next 5 months will determine how quickly the reform delivers lower unpaid super, better transparency and improved retirement outcomes.
Early testing, strong governance and deep collaboration across the ecosystem will be critical.
