This article/resource was written prior to the Federal Treasurer’s announced changes to the Division 296 tax measure on 13 October 2025.
As debate resumes post-election, Australia’s proposed Division 296 measure, which introduces an additional 15 per cent tax on superannuation earnings for total balances exceeding $3 million, remains in limbo. While the Federal Government maintains an intended start date of 1 July 2025, Parliamentary delays will almost certainly result in the proposal becoming retrospective law. In this post, I’ll explore the implications of this delay, the Government’s rationale, broader impacts on confidence in the superannuation system, and strategic pathways that may yet be available.
1. Retrospective Legislation: Undesirable, Even When Foreseen
The Government’s position rests on the assertion that, as the Division 296 measure has been in the public domain for over two years (including a lapsed Bill prior to the 2025 Federal election), its retrospective application is justifiable. Moreover, with an estimated 80,000 individuals directly affected, the measure may seem limited in its reach.
However, the principle at stake is broader: retrospective legislation, even where foreshadowed and subject to consultation, creates legal and commercial uncertainty. Critically, there remains the strong possibility that amendments may be introduced when the Bill is eventually presented. This means the final legislative form and its practical impact could change, and then be applied to, and potentially impacting, actions taken before there was a settled law. Such uncertainty, especially in tax and superannuation where compliance and planning horizons are long, is universally regarded as undesirable by practitioners, regulators, and ultimately, the community.
2. Systemic Confidence: A Precedent Beyond the ‘80,000’
The impact of retrospectivity in law is rarely confined to those directly affected. For superannuation, the principle of prospectivity underpins confidence, not just for the so- called ‘top end of town’, but for all Australians who participate in a system designed to operate transparently and under clear rules. Each instance where retrospective changes are made risks setting a precedent. This, in turn, saps confidence in the long- term stability of the superannuation system, undermining the willingness of millions of Australians to engage in long-term savings decisions under the expectation of certainty and fairness.
3. Consistency with the Legislated Objective of Superannuation
The recently enacted objective of superannuation – ’to preserve savings to deliver income for a dignified retirement… in an equitable and sustainable way’, sets a guiding norm for future policy. It raises a critical question: can legislation that undermines certainty through retrospective effect genuinely be labelled as advancing equity and sustainability? There is a disconnect between this newly established objective and actions that erode the integrity of the system through uncertainty and retrospective lawmaking. Superannuation policy, above all, must support confidence and predictability as core elements of its long-term sustainability.
4. Strategic Considerations and Potential Pathways
The Government’s reluctance to defer the commencement of Division 296 from 1 July 2025 is understandable given fiscal forecasts and the need to demonstrate revenue commitments in the Federal Budget. Yet, prioritising revenue over sound policy implementation risks establishing a poor precedent and undermining trust in future reforms. There are compromise options under discussion, including the Greens’ suggestion: lowering the threshold from $3 million to $2 million with ongoing indexation (maybe aligning it with the indexation of the general transfer balance cap) and shifting the start to 1 July 2026. While this would likely result in short-term revenue losses, it potentially delivers increased collections over the forward estimates and, more importantly, root future changes in law that is settled and prospective, not retrospective.
The Government has stated that their proposed Division 296 measure is a critical measure for the future sustainability and equity of tax concessions, but even more critical is the way in which fiscal reforms are introduced and implemented. The superannuation system’s integrity and the confidence of the broader public should not be collateral damage in the pursuit of revenue or legislative timelines. As policy professionals and stakeholders, we must advocate for processes that protect the system’s long-term strength even, and especially, when in the eyes of the Government, urgent reform is needed.
I welcome the perspectives of fellow superannuation professionals, advisers and policy watchers. Do you see prospectivity as a line in the sand for super reform, or are retrospective measures a pragmatic necessity in today’s environment?
