The 2026 Federal Budget contained several significant tax announcements, including proposed changes to:
- negative gearing;
- how to calculate capital gains tax;
- the taxation of discretionary trusts.
This article focuses specifically on the proposed changes to the taxation of discretionary trusts, and what they may mean for clients with testamentary trust arrangements in their wills. As you will see, the situation is not as alarming as early headlines may have suggested. For most people, the fundamentals of sound estate planning have not changed.
What did the budget announce?
The Commonwealth Government announced its intention to impose a minimum tax rate of 30% on the taxable income of discretionary trusts. Under the proposed rules:
- The trustee of a discretionary trust will be subject to a minimum 30% rate of tax on the trust’s taxable income.
- Beneficiaries who receive distributions will continue to pay tax at their own applicable marginal rate.
- Individual and non-corporate beneficiaries will receive a non-refundable tax credit for the tax paid by the trust – preventing double taxation, though not providing a refund where the credit exceeds the beneficiary’s tax liability.
The Budget announcement has therefore understandably raised questions for clients who have testamentary trusts in their existing wills, or who are currently planning their estates with these structures in mind.
Which Testamentary Trusts are affected?
The announcement confirmed that testamentary trusts not already in existence at 7.30pm AEST on 12 May 2026 will be subject to the new rules. Because testamentary trusts only come into existence when a willmaker dies, any trust arising from the death of a person who was still alive at that time will fall within the new regime – subject to how the legislation ultimately defines the relevant timing.
Optional Testamentary Trusts preserve flexibility
Many wills are drafted so that the testamentary trust is optional – the beneficiary (or another nominated party) has the right to choose, after the willmaker’s death, whether to receive the inheritance personally or through the trust. These are often referred to as optional testamentary trusts.
If your will uses only optional testamentary trusts, the Budget announcement does not create a problem. After the willmaker’s death, the relevant party can assess the tax and personal circumstances at that time, and make an informed choice about the most appropriate structure. There is no risk of being locked into an adverse outcome. The estate retains full flexibility.
Forced Testamentary Trusts are still broadly effective
Some wills require the testamentary trust to come into existence automatically – without the beneficiary having a choice. These are called forced testamentary trusts.
Even under the proposed new rules, forced testamentary trusts will generally remain an effective structure. This is because the income splitting opportunities that arise from investing the inheritance within the trust remain available – and the asset protection benefits are entirely unaffected by the new tax rules.
There is, however, one important but abnormal exception to watch: if the forced testamentary trust is structured so that income must pass to a company beneficiary, that company would not receive the benefit of the non-refundable tax credit available to individual beneficiaries. The result would be an effective tax rate in excess of 60%. This is a structure to review carefully with your lawyer. But as noted, it is not normal.
Aside from this specific scenario, forced testamentary trusts remain a sound and defensible estate planning approach under the proposed changes.
What about companies as alternatives?
One question that naturally arises is whether a company might serve as an effective alternative vehicle for receiving an inheritance.
Passing capital-appreciating wealth into a company creates significant difficulties in extracting it later without adverse tax and compliance consequences. And as noted above, where a company is a beneficiary of a testamentary trust, it will not receive the benefit of the tax credit – resulting in that 60%+ effective rate.
For most estates, the practical choice therefore remains between two options:
- Giving the inheritance directly to the intended human beneficiary; or
- Giving the inheritance to a testamentary trust for the benefit of that person.
Giving the inheritance directly means losing income splitting and asset protection entirely. The beneficiary’s full marginal tax rate applies to all income generated by the inherited assets. For many beneficiaries – particularly those with significant other income – this is a materially worse outcome.
The bottom line for your Estate Planning
Our view on what the Budget announcement means for clients can be summarised as follows:
- The Government’s objective was to raise additional revenue from discretionary trusts. That is, broadly, what it is – and while we will work carefully to manage outcomes once the law is known, clients should not expect a pathway to avoid the new rules entirely.
- Optional and forced testamentary trusts remain effective estate planning structures. For the vast majority of clients, the Budget announcement does not change the fundamental case for using them.
- Income splitting and asset protection – two of the primary reasons to use a testamentary trust – continue to be available under the proposed changes.
- The main exception requiring attention is any testamentary trust that distributes income to a company beneficiary or requires the trustee of the testamentary trust to distribute income to a company beneficiary. If your estate planning includes such an arrangement, it is worth reviewing it with your estate planning lawyer.
- If your will is already signed or you are in the process of finalising one, you can generally proceed with confidence – unless your structure involves forced distributions to a company.
