The Benefits of Testamentary Trust Wills Explained

September 9, 2025

Testamentary Trust Wills provide significant benefits for individuals and families planning the distribution of their estates in Western Australia, particularly in terms of asset protection, tax efficiency, and supporting vulnerable beneficiaries. These trusts are established within a Will and become effective upon death, offering tailored advantages for diverse family circumstances.


Key Benefits of Testamentary Trust Wills


Asset Protection


  • Safeguards inheritance from creditors, bankruptcy, and family law disputes by holding assets within a trust rather than direct ownership by beneficiaries.


  • Shields assets from potential misuse or waste by beneficiaries with high-risk behaviours such as gambling, financial instability, or poor money management.


  • Protects funds from being included in divorce settlements, ensuring they remain accessible only to intended family members.


Tax Advantages


  • Optimises tax outcomes by enabling income splitting among beneficiaries, especially those on lower marginal tax rates.


  • Allows income distributed to minor children (under 18) via a testamentary trust to receive the full adult tax-free threshold (around $19,000–$22,000 per child annually, tax-free), compared to only about $500 in a standard family trust.


  • Provides flexibility to defer tax liabilities for overseas beneficiaries by controlling the timing and distribution of income.


Support for Vulnerable and Young Beneficiaries


  • Helps ensure responsible use of inherited assets by enabling trustees to set age thresholds (e.g., 21, 25, or older) for the release of funds to younger beneficiaries.


  • Allows creation of specialised trusts for beneficiaries living with disabilities, including Social Security Act 1991 (Cth) compliant Special Disability Trusts.


  • Can provide long-term security for those who require ongoing support, such as family members with health challenges or special needs.


Estate Planning Flexibility


  • Highly customisable trusts can be tailored for one person, an entire family, or multiple generations, addressing complex family or blended family situations.


  • Enables control over how and when assets are distributed, including restricting access to certain beneficiaries or protecting inheritance lines within families.


  • Trustees are chosen to ensure accountability, oversight, and alignment with the intentions of the Will-maker, often with recommendations for two trustees to reduce risks.


Who Should Consider a Testamentary Trust Will?


  • Individuals leaving substantial estates (often $2,000,000 or more) including superannuation or life insurance.


  • Estates intended to support minor children, vulnerable adults, or those likely to face relationship or financial risks.


  • Families wishing to maximise tax savings and asset protection across generations.

The Federal Budget announced on 12 May 2026 introduces a minimum 30% tax on certain discretionary trusts, but Testamentary Discretionary Trusts remain a powerful and practical Estate Planning tool for most families. What the Budget changed — quickly and clearly The Government has proposed a minimum 30% tax on the taxable income of discretionary trusts, to apply at trustee level from the legislation’s effective date as announced in the Budget. The measure is designed to limit income-splitting through discretionary trusts and to bring trust taxation closer to the taxation of other entities. Certain trusts and types of income are excluded from the measure — including Fixed Testamentary Trusts and Special Disability Trusts created by Wills, and income from assets of Testamentary Discretionary Trusts that existed at announcement time. The real headline you should read first Despite the headlines, Testamentary Discretionary Trusts remain a strong Estate-Planning choice — they still protect inheritances from relationship breakdowns and give your Executor and family the flexibility to manage distributions over time. Where a trust already distributes income to beneficiaries who pay tax at 30% or more, there will be no increase in the overall tax paid — the Budget’s minimum tax simply matches what those beneficiaries already pay. How the new tax will actually affect families For families that historically flowed trust income to low‑tax-rate beneficiaries (for example, children with little other income), the trustee-level 30% will increase tax payable unless the family’s overall tax position already sat at or above that rate. Non-corporate beneficiaries will receive non-refundable tax credits for tax paid by the trustee, which reduces the risk of double taxation though it does not create a refund if the beneficiary’s personal rate is lower than 30%. Why you should still consider a Testamentary Discretionary Trust ( TDT ) Protection from relationship breakdowns: A TDT ring‑fences the inheritance and makes it far harder for divorcing spouses or de facto partners to claim those assets directly. This protection is often the primary reason clients choose TDTs, and it is unaffected by the Budget change. Control and tailored distributions: TDTs let you set rules for how and when beneficiaries benefit — essential where beneficiaries are young, vulnerable, have special needs, or where blended families require careful balancing. Tax planning remains possible: Although some tax advantages may be reduced for low‑income beneficiaries, many families will see no net tax rise because distributions are already taxed at higher marginal rates. Even where there is more tax payable, the trade-off with asset protection and control can still make a TDT the better choice. Practical next steps for your Estate Plan Don’t panic — review, don’t rip up: If you already have a Will with a Testamentary Discretionary Trust, your plan may be unaffected depending on timing and how distributions are made; get tailored advice before taking action. If you are planning a new Will, speak to an advisor about how a TDT will sit alongside the announced minimum tax rules, whether rollover relief or restructuring options are relevant to you, and whether a Fixed Testamentary Trust or alternate structure may be preferable. Consider cashflow and timing: the trustee will pay tax at the trustee level, so trustees may need to allow for the timing of tax payments and the availability of credits to beneficiaries. A short illustration Family A distributes trust income largely to adult children who already pay tax at 32% — the imposition of a 30% trustee tax will not increase their family’s total tax burden. Family B distributes to low‑income minor children who pay little or no tax — Family B may face higher tax under the new rules.

A new year is the perfect time to revisit an important question: is your Will still up to date? Many people make a Will once and then leave it untouched for years. But life rarely stays still. Relationships change, children are born, assets are bought and sold, businesses evolve, and family circumstances shift. A Will that once reflected your wishes may no longer do so. For that reason, reviewing your Will regularly is one of the simplest ways to protect the people and assets that matter most. Why people delay updating their Will It is easy to put off Estate Planning. Some people assume their Will is “good enough” because nothing dramatic has happened. Others feel uncomfortable thinking about what happens after they are gone. In practice, the most common reason Wills become outdated is not neglect in a dramatic sense, but everyday change. You may have: Married or separated. Had children or grandchildren. Bought property. Started or sold a business. Gained or lost significant assets. Named an Executor who is no longer suitable or available. If any of these apply, your current Will may need review. What can happen if a Will is outdated An outdated Will can create confusion, delay, and conflict at exactly the moment your family is already dealing with loss. It may also fail to reflect your real intentions. For example, assets may pass to someone you no longer intended to benefit, or a chosen Executor may no longer be the right person to manage the Estate. In some cases, the wording of an old Will can even create disputes that could have been avoided with a simple update. When to review your Will A good rule of thumb is to review your Will after any major life event, and otherwise every few years. You should consider an update if you have experienced: A marriage, divorce, or de facto relationship change. The birth or adoption of children. A death in the family. A major change in assets or liabilities. A move interstate or overseas. A change in your wishes about guardianship for your children, gifts, or Executors. Even if nothing major has changed, a periodic review helps ensure your instructions remain clear and legally effective. A simple process can prevent future problems Updating a Will does not have to be complicated. In many cases, a short review with a lawyer is enough to confirm whether the existing document still works or whether a new will is needed. A proper review can also identify related issues, including: Powers of attorney. Appointment of guardians. Superannuation nominations. Business succession arrangements. Asset ownership structures. These matters often work together, so an estate plan should be considered as a whole rather than as a single document. The takeaway The start of a new year is a useful reminder to get organised, and your Will should be part of that process. If your circumstances have changed, or if it has been several years since your last review, now is a sensible time to take another look. A current, well-drafted Will can save your family stress later and help ensure your wishes are carried out clearly.
