As a self-managed super fund (SMSF), you'll need to prepare for increased contribution volumes and stronger error handling from 1 July 2026 as part of Payday Super readiness.
To help with this transition, we will run SuperStream Contributions v3.0 activities to support Payday Super. Conformance testing cohorts begins from March 2026 for Better Error Messaging, followed by Message Implementation Guide (MIG) changes from May 2026. Testing and cutover guidance is available on the ATO’s Software Developers page under Contributions v3.0.External Link
You need to submit your plans to implement Better Error Messaging and MIG changes to ensure you can be allocated to a testing cohort. Engaging early helps us allocate you with a cohort that meets your testing timeframes. This is a critical step to ensure that you are compliant with Payday Super requirements.
