Testamentary Trust Key Takeaways
A Testamentary Trust is a trust created under a Will that only starts after the will‑maker dies, and it can be a powerful tool for Australian families.
- Key Testamentary Trust benefits Australia include asset protection, income splitting and access to adult tax rates for children on trust income.
- These trusts are especially useful for young or vulnerable beneficiaries, blended families and business owners worried about future claims.
- Professional Australian legal and tax advice is essential to set up and administer a Testamentary Trust correctly.
What Australians Should Know About a Testamentary Trust
In Australia, a Testamentary Trust is a trust established by a Will that only comes into effect on the death of the will‑maker. Unlike a family (discretionary) trust you create during your lifetime, the terms of a Testamentary Trust are written into the Will and are administered by the trustee after probate.
In practice, the Will usually names a trustee (or several) and sets out who can benefit, how income and capital can be distributed, and any conditions (for example, age or behavioural conditions). The assets you leave to the trust form part of your estate, but once transferred into the trust they are separated from the personal ownership of the beneficiaries.
Australian tax law gives Testamentary Trusts some unique advantages, especially for children, and the structure can also provide strong protection against various risks. Understanding how does a testamentary trust work in Australia helps you decide if it fits your family’s estate plan. For a related guide, see CBA Share Price Jumps Amid Strong ASX Momentum.
How Does a Testamentary Trust Work in Australia Day to Day?
Once probate is granted and estate debts and taxes are paid, the executor transfers relevant assets into the Testamentary Trust. From there, the trustee manages those assets and distributes income and/or capital according to the Will and Australian trust law.
Key roles in a Testamentary Trust
The people involved in a Testamentary Trust include:
- Trustee – controls the trust, decides how to invest and how to distribute income and capital within the rules of the Will.
- Primary beneficiaries – the main people intended to benefit (often a spouse and/or children).
- General beneficiaries – a broader class (for example, spouses, children, grandchildren and sometimes related companies or trusts).
- Appointor or principal – in some structures, a person with the power to hire and fire the trustee.
What can sit inside the trust?
A Testamentary Trust can hold a wide range of assets, including:
- Cash and term deposits
- Listed shares and managed funds
- Investment properties and, in some cases, the family home
- Business interests and shareholder loans
Because of this flexibility, the structure is widely used to manage inheritances strategically rather than simply giving assets outright.
Asset Protection Testamentary Trust Strategies for Australian Families
One of the main Testamentary Trust benefits Australia is asset protection. While no structure is bullet‑proof, a well‑drafted asset protection testamentary trust can significantly reduce the risk that your children’s or spouse’s inheritance will be lost in future disputes or financial trouble.
Shielding inheritances from creditors and bankruptcy
If a beneficiary is (or later becomes) bankrupt or is sued, assets held in a Testamentary Trust are generally not their personal property. The trustee holds legal title, and the beneficiary only has a right to be considered for distributions. This can place the assets one step removed from creditors, subject to complex bankruptcy and trust law rules.
Example: Your adult son runs a small construction business in Sydney. Years after your death, a major claim sends his company into liquidation and he is declared bankrupt. Because his inheritance sits in a discretionary Testamentary Trust rather than in his personal name, the trustee has more flexibility to hold back or redirect benefits so that the trust assets are better protected from the bankruptcy trustee.

Protecting against family law property settlements
The Family Court of Australia can take trust interests into account when assessing property settlements. However, if the trust has a genuinely independent trustee and the beneficiary has no guaranteed entitlement, the court is more likely to treat the trust as a “financial resource” rather than an asset owned outright.
Example: Your daughter in Melbourne receives her inheritance via a Testamentary Trust. Years later, her relationship ends. Instead of her former partner having a direct claim over specific inherited assets, the trust may be considered as one factor in the financial mix, giving her more leverage in negotiations than if the inheritance was simply in her own name.
Managing spendthrift or high‑risk beneficiaries
A Testamentary Trust is invaluable when you are concerned that a beneficiary might quickly waste a lump sum. By appointing a trusted person or professional as trustee, you can stagger access and tie distributions to needs or milestones.
Example: You leave $800,000 to your 25‑year‑old son who has a history of gambling and poor financial decisions. Rather than gifting the amount outright, you direct the trustee to pay his rent and reasonable living costs from the trust, with limits around large capital withdrawals. This approach can preserve capital for the long term.
Supporting vulnerable or young beneficiaries
A testamentary trust for minor children Australia is especially powerful when both parents die or where a child has a disability, addiction or mental health challenges. The trustee can apply income for education, therapy, housing and day‑to‑day living while protecting the underlying capital.
In more complex cases, a Testamentary Trust can sit alongside a Special Disability Trust, Centrelink arrangements and NDIS planning, giving a structured framework for long‑term support.
Tax Advantages of Testamentary Trusts for Australian Beneficiaries
Beyond asset protection, the tax advantages of testamentary trusts are a major reason Australian advisers recommend them. Because the trust is created by a Will, it receives some favourable treatment under the Income Tax Assessment Act 1936 and 1997.
Powerful income splitting across family members
A Testamentary Trust is usually discretionary, meaning the trustee can decide each year which beneficiaries receive income and how much. This allows income to be directed to family members on lower marginal tax rates and away from high‑income earners. For a related guide, see Discretionary Trust Explained: Benefits, Risks and Tax Rules.
Example: Your spouse earns $200,000 per year, while your adult children are studying and working part‑time. The trustee can distribute more investment income to the adult children, who may pay tax at lower rates or even nil, reducing the overall family tax bill.
Adult tax rates for children from testamentary sources
In a standard family trust, “unearned” income paid to children under 18 is usually taxed at penalty rates. A key benefit of a Testamentary Trust is that income derived from property left to the trust under a Will can be treated as “excepted trust income”. This lets minors access the ordinary adult tax‑free threshold and marginal rates on that income.
Example: Your 10‑year‑old child receives $20,000 of investment income from a Testamentary Trust. Provided the income meets the excepted trust income rules, they may pay little or no tax, instead of facing high penalty rates that would apply if the same income came from a standard family trust you set up during your lifetime.
Capital gains tax (CGT) and flexibility
When assets pass from the deceased estate into a Testamentary Trust, CGT rollover relief may be available in many situations, so no immediate capital gain is triggered on death. Subsequent gains realised by the trust can be distributed to beneficiaries in a tax‑efficient way, often to those with capital losses or lower income.
Australian CGT rules are detailed and depend on the type of asset, when it was acquired and whether it was a main residence. For accurate guidance, the Australian Taxation Office’s guidance on deceased estates and trusts is a helpful starting point, particularly the ATO’s page on tax and deceased estates.

When a Testamentary Trust Makes Sense in Australia
Not every Will needs a Testamentary Trust, but for many Australian families it can be a logical upgrade from a simple Will. Consider whether the structure aligns with your goals and family circumstances.
Common situations where a Testamentary Trust is valuable
- You have minor children and want inheritance funds managed until they are older and more responsible.
- You are in a blended family and wish to benefit both a current spouse and children from a previous relationship, with controls around timing and amounts.
- One or more beneficiaries are in high‑risk occupations or run small businesses exposed to litigation and insolvency risk.
- A beneficiary has a disability, addiction or poor money management history, making a lump sum gift inappropriate.
- Your estate is significant (often $500,000+) and you want to maximise tax efficiency across family members.
Eligibility and practical prerequisites
There is no strict asset minimum in law, but you will generally want:
- Enough assets to justify the setup and ongoing administration costs.
- At least one person you trust to act as trustee (or willingness to appoint a professional trustee or co‑trustee).
- A Will prepared or reviewed by an Australian solicitor experienced in estate planning and trusts.
- Accountants who understand trust tax returns and ATO reporting obligations.
A simple planning checklist for Australians
- Clarify who you want to benefit, and in what priority or proportions.
- Decide who should be trustee (and a backup) and whether they need professional co‑trustees.
- Think about any conditions: ages, education milestones or caps on discretionary payments.
- Review superannuation death benefit nominations and life insurance so they can flow into the trust if appropriate.
- Meet with both an estate planning lawyer and a tax adviser together so the structure works from both perspectives.
Common Misconceptions About Testamentary Trust Benefits in Australia
Misunderstandings about Testamentary Trusts can stop families from using them or create unrealistic expectations. Clearing these up helps you use the structure wisely.
“A Testamentary Trust makes assets completely untouchable”
Even the best asset protection testamentary trust is not an absolute shield. Courts can, in certain circumstances, look through trust structures, especially where the beneficiary effectively controls the trustee or where the trust is used to defeat creditors or family law claims. The goal is to improve your position, not create guaranteed immunity.
“They are only for the very wealthy”
While very large estates often use Testamentary Trusts, Australian families with moderate wealth can also benefit, especially if there are minor children, businesses or vulnerable beneficiaries. The key is whether the potential tax savings and asset protection justify the added complexity and cost.
“They are too hard to manage”
There are extra steps: separate bank accounts, annual trust tax returns, trustee resolutions and record‑keeping. However, with a good accountant and clear guidance at the start, most responsible trustees manage comfortably. Many lawyers and accountants now have streamlined processes specifically for Testamentary Trusts.
“I can just set up the trust later”
A Testamentary Trust must be created by your Will and only arises on your death. You cannot simply decide after the fact to turn a straightforward inheritance into a Testamentary Trust. If you want your estate to be able to use this structure, the Will needs to be drafted with the trust included from the outset.
Professional Advice and Next Steps for Setting Up a Testamentary Trust
Because Testamentary Trusts sit at the intersection of Wills, tax law, superannuation and sometimes family law, independent professional advice in Australia is essential. A good starting point is to read general guidance from bodies like Moneysmart on estate planning and then meet with a solicitor who focuses on estate planning.
After exploring your options, you can decide whether to:
- Include a fully discretionary Testamentary Trust for each key beneficiary.
- Use one “family” Testamentary Trust for all beneficiaries.
- Limit the trust to specific assets (for example, your investment property portfolio).
- Rely on a simpler Will if your situation does not justify the added complexity.
Before signing a new Will, ask your lawyer and accountant to walk you through example distributions, tax outcomes and administration obligations so you and your chosen trustees are comfortable with how the trust will work in real life.

In summary, a Testamentary Trust can be a powerful way for Australians to protect family wealth, support vulnerable beneficiaries and legitimately reduce tax, but it must be carefully designed and administered. Before relying on one, arrange tailored advice from Australian legal and tax professionals who understand your full financial picture and family dynamics.
Frequently Asked Questions About Testamentary Trust
What is a Testamentary Trust in Australia?
In Australia, a Testamentary Trust is a trust created under a Will that only comes into existence after the will‑maker dies. It allows a trustee to hold and manage estate assets for beneficiaries, often providing asset protection and tax planning benefits compared with giving inheritances outright.
How does a Testamentary Trust work in Australia for day-to-day management?
After probate, assets are transferred from the estate into the Testamentary Trust, and the trustee then manages investments, pays expenses and decides how much income and capital to distribute to beneficiaries each year in line with the Will and trust law, lodging a trust tax return annually.
What are the main Testamentary Trust benefits Australia residents should know?
Key benefits include better asset protection from creditors and relationship breakdowns, flexible income splitting among family members, access to adult tax rates for minors on certain income, and more control over how and when beneficiaries receive their inheritance.
Can a Testamentary Trust protect assets from divorce or separation?
A Testamentary Trust can improve protection because inherited assets are held by a trustee rather than directly by the beneficiary, so in family law proceedings the trust is often treated as a financial resource instead of property owned outright, but courts still have wide powers and can consider trust assets when making settlements.
Is a Testamentary Trust good for minor children in Australia?
Yes, a Testamentary Trust is often ideal for minor children because it allows a trusted adult trustee to manage funds for education and living costs, delays full control until a chosen age, and can give minors access to adult tax rates on trust income that qualifies as excepted trust income.
Who should be the trustee of a Testamentary Trust ?
The trustee should be someone reliable and financially responsible, such as a spouse, adult child, trusted friend, professional adviser or a combination of lay and professional co‑trustees, and it is wise to also nominate backup trustees in case your first choice cannot act.
What are the tax advantages of testamentary trusts in Australia?
Tax advantages include the ability to split income among several beneficiaries, potential access to adult tax‑free thresholds and marginal rates for minors on excepted trust income, and flexibility to distribute capital gains to beneficiaries with lower income or capital losses, which can reduce the overall family tax burden.
Do children under 18 really get adult tax rates in a Testamentary Trust ?
Children under 18 can access adult tax rates on income from a Testamentary Trust that qualifies as excepted trust income, meaning it is generated from property left to them via the Will; however, careful structuring and record‑keeping are needed to ensure the rules are met and penalty rates do not apply.
How is a Testamentary Trust different from a family discretionary trust?
A family discretionary trust is usually set up during your lifetime with a trust deed, while a Testamentary Trust is created by your Will and only begins on your death; tax rules for minors are more favourable in a Testamentary Trust, and the structure is closely tied to your estate planning goals.
Does setting up a Testamentary Trust avoid capital gains tax on death?
Australian law often allows CGT rollover relief when assets pass from a deceased estate to beneficiaries or to a Testamentary Trust, so no immediate capital gain arises on death, but future disposals by the trust may trigger CGT, which can then be managed through careful distribution strategies.
What does it cost to set up a Testamentary Trust ?
The cost is usually built into the fee for preparing a more complex Will and can range from a few hundred to several thousand dollars depending on the lawyer, state and complexity, with ongoing costs for accounting, tax returns and trustee administration every year.
Can I have more than one Testamentary Trust in my Will?
Yes, you can include multiple Testamentary Trusts in a single Will, for example one for each child or one for your spouse and one for your children, and you can tailor the terms of each trust to suit the needs and risks of each beneficiary group.
Can superannuation death benefits be paid into a Testamentary Trust ?
In some cases, superannuation death benefits can be directed to your estate and then paid into a Testamentary Trust, but this depends on the fund’s rules, your death benefit nominations and tax implications, so coordinated advice from your financial adviser, super fund and lawyer is essential.
How long can a Testamentary Trust last in Australia?
A Testamentary Trust can generally last up to the maximum period allowed under the relevant state or territory’s perpetuity laws, often up to 80 years from creation, but your Will can specify an earlier end date or specific events that trigger winding up the trust.
Does a Testamentary Trust affect Centrelink or pension entitlements?
Yes, trust interests and distributions can affect Centrelink asset and income tests, both for beneficiaries and sometimes for the surviving spouse, so it is vital to get integrated advice on how the Testamentary Trust interacts with age pension or disability support payments.
Can I change the terms of a Testamentary Trust after the Will is signed?
Once you die, the terms written into your Will are usually fixed, although in some circumstances the trustee or beneficiaries may seek court approval for variations; while you are alive, you can change the Will and the trust terms by signing a new or updated Will prepared by a solicitor.
Who should consider a Testamentary Trust in their estate plan?
Australians with minor children, blended families, business ownership, vulnerable beneficiaries or estates large enough that tax and asset protection are meaningful issues should seriously consider including one or more Testamentary Trusts in their Wills.
Are Testamentary Trusts only useful for very large estates?
No, while they are common for high‑net‑worth families, Testamentary Trusts can also be worthwhile for more modest estates if there are young beneficiaries, significant life insurance, or notable asset protection and tax planning concerns that justify the additional complexity and cost.
What are the risks or downsides of a Testamentary Trust ?
Downsides include extra administration and accounting costs, complexity for trustees, potential family disagreements over distributions, and the fact that poorly drafted trust provisions can cause confusion or reduce flexibility, which is why careful drafting and trustee selection are so important.
Should I get legal and tax advice before using a Testamentary Trust ?
Yes, Testamentary Trusts involve complex legal and tax rules, so you should always seek personalised advice from an Australian estate planning lawyer and a qualified tax adviser who can tailor the structure to your assets, family situation and long‑term goals.
