Family Trust Reform: Navigating the 30% Minimum Tax Floor
The federal government’s proposed 30% minimum tax on discretionary trusts fundamentally shifts investment viability by curbing historical income-splitting advantages. With consultation ongoing through July 2026, high-net-worth investors face a pivotal transition period where the utility of existing trust structures will depend on the effectiveness of new rollover relief measures.

The Mechanics of the 30% Trustee Floor
As outlined in the 2026-27 Budget, the core of the reform involves shifting the primary tax liability to the trustee. By imposing a 30% minimum rate at this level, the policy seeks to ensure a fairer rate of tax on discretionary trust income, effectively aligning trust taxation with the corporate rate. Economists note this creates a new tax-neutrality baseline, which diminishes the historical incentive to use discretionary trusts for aggressive income splitting. The design mandates that the trustee, who controls distributions, manages the tax burden directly, representing a significant departure from traditional flow-through tax mechanisms.
Technical Hurdles: The Non-Refundable Credit Impact
A critical technical feature currently under review by industry professionals, as highlighted by Accountantsdaily on 10 July 2026, is the use of non-refundable credits. Under this framework, beneficiaries—excluding corporate beneficiaries—receive credits for tax paid by the trustee. Academics suggest this mechanism prevents beneficiaries in lower tax brackets from recovering excess tax paid at the trustee level, effectively removing the tax-smoothing advantages that were previously central to the discretionary trust model. Skeptics argue this shift may create an administrative burden that disproportionately affects smaller family vehicles rather than curbing high-net-worth tax avoidance as intended.
Restructuring and the Path Ahead
The federal government released a formal consultation paper on the implementation of these reforms on 8 July 2026. To assist in the transition, the government has proposed expanded rollover relief for small businesses and other entities seeking to restructure out of discretionary trusts. Practitioners highlight that the operational viability of existing structures will now hinge on the accessibility and scope of these relief measures. If the costs of transitioning remain prohibitive, many investors may find themselves effectively locked into legacy structures that no longer align with their original financial planning objectives.
Investors should stress-test their current trust holdings against the 30% floor to determine whether the benefits of structural flexibility still outweigh the costs of potential future restructures.
