Why Your Superannuation Doesn't Automatically Fall Under Your Will

Most Australians assume their superannuation will simply pass to their loved ones when they die, distributed according to their Will alongside the family home and other assets. This is a dangerous misconception that can cost your family hundreds of thousands of dollars.

Superannuation is held within a trust structure — whether that's an industry fund, retail fund, or a Self-Managed Superannuation Fund (SMSF). Because it sits inside a trust, your super is a separate asset class governed by the fund's trust deed and the Superannuation Industry (Supervision) Act 1993 (Cth), not by your Will.

When you die, your superannuation trustee — not your executor — decides what happens to your death benefit, unless you've made a valid nomination. For SMSF members in Melbourne and across Victoria, this distinction is critical. Without a properly drafted death benefit nomination, the remaining SMSF trustee (or the trustee's legal personal representative) exercises discretion over who receives your benefit and in what form.

For high-net-worth individuals with substantial SMSF balances, failing to integrate your superannuation into your broader estate plan can result in:

  • Benefits being paid to unintended recipients
  • Significant and avoidable tax liabilities for your adult children
  • Family disputes and potential litigation
  • Loss of asset protection that a testamentary trust would otherwise provide

The Four Death Benefit Nomination Options

When it comes to directing your SMSF death benefit, you have four options — each with significantly different legal consequences. Understanding these options is the foundation of effective SMSF estate planning in Melbourne.

1. No Nomination

If you make no nomination at all, the remaining SMSF trustee has full discretion to pay your death benefit to one or more of your dependants, or to your legal personal representative (your executor). This creates uncertainty and potential for family conflict, particularly in blended family situations.

2. Non-Binding Nomination

A non-binding death benefit nomination guides the trustee but does not legally compel them to follow your wishes. The trustee must consider your nomination but can override it if they believe a different distribution is more appropriate. This is sometimes described as a "wish list" — it carries moral weight but no legal force.

3. Lapsing Binding Death Benefit Nomination (BDBN)

A lapsing BDBN is a legally binding direction to the trustee that expires every three years. If valid, the trustee must follow it. The key risk: if you forget to renew it, or if it was improperly witnessed, it becomes invalid and the trustee reverts to exercising discretion. For a lapsing BDBN to be valid, it must comply with Regulation 6.17A of the SIS Regulations.

4. Non-Lapsing Binding Death Benefit Nomination

A non-lapsing BDBN remains in force until you revoke or amend it — there is no three-year expiry. However, not all SMSF trust deeds permit non-lapsing nominations. Your deed must be reviewed to confirm it allows this type of nomination, and the nomination itself must satisfy the deed's execution requirements.

Key takeaway: For the superannuation testamentary trust strategy to work, you need a valid BDBN (lapsing or non-lapsing) that directs your death benefit to your Legal Personal Representative — that is, your executor. This is the critical first step.

Nomination Type Binding? Expiry Risk Level
No nomination No — trustee discretion N/A High
Non-binding No — guidance only None Moderate
Lapsing BDBN Yes 3 years Low (if renewed)
Non-lapsing BDBN Yes Until revoked Low

The 17% Death Benefits Tax Problem

Here is where SMSF estate planning becomes genuinely urgent for families with adult children.

Under Australian tax law, superannuation death benefits are treated differently depending on who receives them. The critical distinction is between tax dependants and non-tax dependants.

Tax dependants (who receive death benefits tax-free) include:

  • Your spouse or de facto partner
  • Your children under 18 years of age
  • Any person financially dependent on you at the time of death
  • Any person in an interdependency relationship with you

Non-tax dependants (who are subject to death benefits tax) include:

  • Adult children over 18 who are not financially dependent on you
  • Other non-dependent beneficiaries

When a superannuation death benefit is paid as a lump sum to a non-tax dependant, the taxable component is taxed at up to 17% — that is, 15% tax plus the 2% Medicare levy. The tax-free component is always received tax-free regardless of who receives it.

Example: Consider an SMSF member in Melbourne with a $2,000,000 superannuation balance, of which $1,400,000 is the taxable component (a common scenario for members who have received concessional contributions over many years). If this benefit is paid directly to their two adult children as a lump sum, the tax payable would be:

$1,400,000 × 17% = $238,000 in tax

That is $238,000 your family loses to the ATO — an outcome that, in many cases, can be significantly mitigated with proper estate planning.

We recommend consulting your accountant or financial adviser for specific tax implications. The above example is illustrative only and does not constitute financial product advice.

The Superannuation Testamentary Trust (STT) Mechanism

A superannuation testamentary trust (sometimes called a "superannuation proceeds trust" or "super testamentary trust") is a legal structure established under your Will that receives your superannuation death benefit and holds it on trust for your beneficiaries.

The mechanism works in three steps:

  1. BDBN to Legal Personal Representative: Your Binding Death Benefit Nomination directs the SMSF trustee to pay your death benefit to your Legal Personal Representative (your executor). This brings the super into your estate.
  2. Executor transfers to the STT: Your Will directs your executor to transfer the superannuation death benefit into the superannuation testamentary trust established under your Will, rather than distributing it directly to beneficiaries.
  3. STT holds and distributes: The testamentary trust holds the funds, invests them, and distributes income to beneficiaries in accordance with the trust terms. This is where the tax advantages arise.

The legal structure is: BDBN → Legal Personal Representative → Superannuation Testamentary Trust → Beneficiaries

Critically, the death benefit itself — the lump sum — is still subject to the applicable tax treatment when it is paid out of the SMSF. The STT does not eliminate the initial death benefits tax on the taxable component. However, it provides significant ongoing advantages in how the inherited wealth is managed, protected, and taxed going forward.

How a Testamentary Trust Distributes Income at Adult Marginal Rates

One of the most powerful advantages of a testamentary trust — including a superannuation testamentary trust — is the income tax treatment of distributions to minor beneficiaries.

Ordinarily, if a minor child (under 18) receives income from a trust, punitive tax rates apply under Division 6AA of the Income Tax Assessment Act 1936. These rates effectively tax minors at the top marginal rate (45% plus Medicare levy) on trust income above $416 per year.

However, income from a testamentary trust is specifically excluded from this penalty. Section 102AG(2)(a) provides that income derived by a minor from a trust estate that arose from a Will (a testamentary trust) is taxed at normal adult marginal rates.

This means:

  • Each minor beneficiary (your grandchild, for example) can receive up to $18,200 per year completely tax-free (the current tax-free threshold)
  • Income above that amount is taxed at progressive adult rates, not penalty minor rates
  • If you have multiple minor beneficiaries, income can be split across them, multiplying the tax-free thresholds

Scenario: A superannuation testamentary trust holding $1,000,000 generates $60,000 in income. The trustee distributes $20,000 each to three grandchildren (all minors). Each grandchild pays tax at adult marginal rates — meaning the first $18,200 per child is tax-free, with only $1,800 per child taxed at the lowest marginal rate (16%). Total family tax: approximately $864 on $60,000 of income. Without the testamentary trust, the same income paid to the minors could attract over $25,000 in tax.

This is a simplified illustration of the legal structure. We recommend consulting your accountant or financial adviser for specific tax calculations applicable to your circumstances. This article discusses legal structures only — it is not financial product advice.

Beyond the tax advantages for minors, a testamentary trust also provides:

  • Asset protection: Assets held in the trust are generally protected from beneficiaries' creditors, including in bankruptcy and family law proceedings
  • Income splitting: The trustee can distribute income flexibly among a class of beneficiaries each year, optimising the overall family tax position
  • Control from beyond: You set the trust terms in your Will, controlling how your wealth is managed and distributed for decades after your death

The New $3M Super Tax (Division 296) and Estate Planning

From 1 July 2025, the Federal Government has introduced Division 296 of the Income Tax Assessment Act 1997, imposing an additional 15% tax on earnings attributable to superannuation balances exceeding $3 million.

This brings the total tax rate on earnings above the $3 million threshold to 30% (the existing 15% within the fund plus the new 15% Division 296 tax).

Key implications for SMSF estate planning:

  • Increased urgency to plan: For members with balances approaching or exceeding $3 million, the combined effect of Division 296 during their lifetime and the 17% death benefits tax at death creates a compounding tax burden that demands proactive planning
  • Interaction with death benefits: Division 296 applies during the member's lifetime, but the death benefits tax applies at death. These are separate but cumulative tax events — proper estate planning addresses both
  • Potential for strategic withdrawals: Some members may consider withdrawing amounts above $3 million to avoid the Division 296 tax, which has flow-on implications for how those funds are held and ultimately distributed on death. These are financial decisions that should be made in consultation with your financial adviser and accountant — WealthShield Legal can then ensure the legal structures support whatever strategy is adopted
  • Review existing estate plans: If your SMSF estate plan was established before Division 296, it should be reviewed to ensure it accounts for this new tax layer
Division 296 is a tax measure — we recommend consulting your accountant or financial adviser for specific modelling on its impact. WealthShield Legal's role is to ensure your legal structures (BDBN, Will, testamentary trust) are optimised to work alongside your financial strategy.

Practical Steps: What Documents You Need

Implementing a comprehensive SMSF estate plan requires several interconnected legal documents. Each must be properly drafted to work together — a gap in any one document can undermine the entire strategy.

Here is what our Principal Lawyer recommends for a complete SMSF estate plan:

  1. BDBN Review and Update
    Your Binding Death Benefit Nomination must be reviewed to confirm it is valid, properly witnessed, and (critically) directs your benefit to your Legal Personal Representative. If your SMSF trust deed doesn't allow non-lapsing BDBNs, the deed may need to be amended. If you have a lapsing BDBN, a system for timely renewal must be established.
  2. Will with Superannuation Testamentary Trust Provisions
    Your Will must include specific provisions establishing a superannuation testamentary trust to receive the death benefit. This is not a standard testamentary trust — it requires tailored drafting to ensure the superannuation proceeds are captured and held on the correct terms. The trust terms should address the trustee, beneficiaries, investment powers, and distribution provisions.
  3. General and Enduring Powers of Attorney
    Your powers of attorney should be updated to cover your SMSF trustee role. If you lose capacity, your attorney needs the legal authority to act as SMSF trustee (or director of the SMSF corporate trustee) on your behalf. Without this, the fund could be left without a properly authorised trustee — creating compliance issues and potential regulatory breaches.
  4. Memorandum of Wishes
    While not legally binding, a Memorandum of Wishes provides guidance to your testamentary trustee on how you would like the trust to be administered. This is particularly important for superannuation testamentary trusts, where the trustee may need guidance on distribution priorities across multiple beneficiaries and generations.
  5. SMSF Trust Deed Review
    The SMSF trust deed itself should be reviewed to ensure it permits the type of BDBN you need (especially non-lapsing), and that it doesn't contain any provisions that could conflict with the estate planning strategy. Older trust deeds, in particular, may not adequately address death benefit nominations.

Important: These documents must work as an integrated system. A BDBN that directs benefits to your Legal Personal Representative is useless if your Will doesn't contain the superannuation testamentary trust provisions to receive them. Similarly, a perfectly drafted Will achieves nothing if your BDBN is invalid or directs benefits elsewhere. This is why SMSF estate planning should be approached holistically, with all documents prepared by the same legal team.

Frequently Asked Questions

When superannuation death benefits are paid to non-tax dependants (such as adult children over 18 who are not financially dependent), the taxable component of the super benefit is taxed at up to 17% — comprising 15% tax plus 2% Medicare levy. This applies to lump sum payments. The tax-free component is always received tax-free. We recommend consulting your accountant or financial adviser for specific tax implications.

Yes. By directing your superannuation death benefit through your Legal Personal Representative to a superannuation testamentary trust established under your Will, the inherited funds can be invested and income distributed to beneficiaries — including minor children and grandchildren — at adult marginal tax rates rather than penalty minor rates. This is a legal structure; we recommend consulting your accountant or financial adviser for specific tax implications.

A BDBN is a legally binding direction to your SMSF trustee specifying who should receive your superannuation death benefit. Unlike a non-binding nomination, the trustee must follow a valid BDBN. There are two types: lapsing (expires every three years) and non-lapsing (remains in force until revoked). For the superannuation testamentary trust strategy, the BDBN must direct the benefit to your Legal Personal Representative.

No. Superannuation is held in a trust structure and is not automatically an estate asset. It does not pass under your Will unless you make a valid death benefit nomination directing it to your Legal Personal Representative (executor). Without a nomination, the SMSF trustee has discretion over who receives the benefit.

Division 296 introduces an additional 15% tax on earnings from superannuation balances above $3 million, effective from 1 July 2025. This brings the total tax rate on earnings above the threshold to 30%. For high-net-worth individuals with large SMSF balances, this creates additional urgency to review estate planning structures and consider the interaction between Division 296 and death benefit taxation. We recommend consulting your accountant or financial adviser for specific tax implications.

A comprehensive SMSF estate plan typically requires: (1) a review and update of your Binding Death Benefit Nomination, (2) a Will that includes superannuation testamentary trust provisions, (3) updated Powers of Attorney to cover SMSF trustee roles, and (4) a Memorandum of Wishes. WealthShield Legal can prepare all of these documents as part of the WealthShield Comprehensive Estate Plan.
