Most Australians assume their superannuation follows their will. It doesn’t. Super is held in a trust on your behalf, which means it sits outside your estate — and without a valid beneficiary nomination, your trustee decides who gets it.
Getting this right matters more than many people realise. The difference between a well-structured nomination and none at all can be tens of thousands of dollars in unnecessary tax, delays in payment, or money going to the wrong person entirely.
Why super doesn’t follow your will
Super is not an asset you own in the conventional sense. It’s held for you by a trustee — either a large retail or industry fund, or the trustees of your self-managed super fund (SMSF). Because you don’t own it directly, it doesn’t form part of your estate and your will has no authority over it.
The exception is if you nominate your estate (your legal personal representative) as the beneficiary. In that case, the death benefit flows to your estate and is then distributed according to your will. This is sometimes the right approach — but it introduces probate, can delay payment, and exposes the money to estate challenges.
Who can receive a super death benefit
The Superannuation Industry (Supervision) Act 1993 (SIS Act) restricts who can receive a super death benefit directly from a fund. Eligible beneficiaries — called SIS dependants — are:
- Your spouse or de facto partner (including same-sex partners)
- Your children of any age — biological, adopted, or stepchildren
- Anyone in an interdependency relationship with you — broadly, people who live together and provide each other with financial and domestic support
- Anyone financially dependent on you at the time of death
- Your legal personal representative (your estate)
Adult children who are financially independent are eligible SIS dependants and can receive the death benefit directly from the fund, but they are not tax dependants — which has significant implications for how the benefit is taxed (covered below).
Types of beneficiary nominations
How you nominate your beneficiaries determines how much discretion your trustee has after you die.
Binding lapsing nomination. The trustee must pay the benefit to the people you nominate in the proportions you specify — provided the nomination is valid. The catch: binding nominations typically expire every three years and must be renewed. If yours lapses and you haven’t updated it, the trustee reverts to its discretion.
Binding non-lapsing nomination. Offered by some funds (and standard for SMSFs), this binds the trustee permanently without expiry. A better option for most people, as it removes the risk of a lapsed nomination catching your family off guard.
Non-binding (“preferred”) nomination. You express a preference, but the trustee retains discretion to pay whoever it considers appropriate — typically your spouse and dependants. Useful in some circumstances but provides no guarantee.
Reversionary pension nomination. If you’re drawing an account-based pension, you can nominate a reversionary beneficiary — usually your spouse — who automatically continues to receive pension payments after you die. The payment keeps flowing without the trustee needing to make a new decision, which can be valuable for cash-flow continuity.
No nomination. The trustee uses its discretion. This is the default for many people who have never engaged with their super fund about this — and it’s the outcome most worth avoiding.
For SMSFs, the trustee structure matters too. If you and your spouse are co-trustees and one of you dies, the surviving spouse becomes sole trustee and has effective control over the fund’s assets. A binding death benefit nomination is still important to ensure clarity and avoid future disputes, particularly where children from prior relationships are involved.
How super death benefits are taxed
The tax treatment depends on two things: the type of beneficiary, and the components that make up the super balance.
Tax dependants vs non-tax dependants
For tax purposes, a tax dependant is narrower than a SIS dependant. Tax dependants include:
- Your spouse or de facto partner
- Children under 18
- Any person in an interdependency relationship with you
- Any person financially dependent on you at the time of death
Adult children who are financially independent are NOT tax dependants, even though they can receive super. This is the most common source of unexpected tax on super death benefits.
The two components
Every super balance is made up of:
- Tax-free component — typically non-concessional (after-tax) contributions you’ve made. This is always paid tax-free, regardless of who receives it.
- Taxable component — concessional contributions, employer contributions, and fund earnings. This is the portion that can be taxed on death.
Tax rates on death benefits
| Recipient | Benefit type | Tax rate |
|---|---|---|
| Tax dependant | Lump sum (any component) | Tax-free |
| Tax dependant | Income stream | Concessional tax treatment |
| Non-tax dependant (e.g. adult child) | Taxable component — taxed element | 15% + Medicare levy (max 17%) |
| Non-tax dependant | Taxable component — untaxed element | 30% + Medicare levy (max 32%) |
| Estate | Depends on ultimate beneficiary | Varies |
For most accumulation phase members, nearly all of their balance is the taxable component (taxed element), because contributions and earnings have been subject to 15% tax inside the fund. That means an adult child receiving $500,000 could face up to $85,000 in tax.
The recontribution strategy
One of the most effective ways to reduce the tax burden on your adult children is a recontribution strategy. The approach involves:
- Withdrawing a lump sum from super (requires meeting a condition of release — typically retirement or age 65)
- Re-contributing that money back into super as a non-concessional contribution
Each dollar recontributed converts taxable component into tax-free component. Because non-concessional contributions go in post-tax, they come back out tax-free — for any beneficiary, including adult children.
The saving is meaningful. Every $100,000 converted from taxable to tax-free component can save an adult child around $17,000 in death benefit tax. For larger balances, the cumulative saving can be substantial.
The strategy requires careful coordination with the non-concessional contributions cap ($130,000 per year, or up to $390,000 using the bring-forward rule if eligible), and it interacts with your total super balance and age. It’s not a DIY exercise — the sequencing, tax modelling, and documentation need to be done deliberately.
What SMSF trustees need to consider
In an SMSF, the trust deed governs what types of nominations are permitted. Older deeds may not allow non-lapsing binding nominations, or may have specific witnessing and renewal requirements. Check your deed before assuming any nomination you’ve made is valid.
SMSFs also need to think about what happens to the fund itself on the death of a member. If a sole member trustee dies, the fund needs a new trustee before assets can be transferred — which can create delays. Corporate trustee structures (where a company acts as trustee) are often better suited to estate planning scenarios because the company continues regardless of individual deaths.
The interaction between super death benefits and the fund’s CGT position is also worth reviewing. A death may trigger a change in the fund’s tax status or the availability of certain concessions, depending on the circumstances.
Practical steps to take now
Getting your super beneficiary arrangements right doesn’t require an overhaul — but it does require deliberate attention.
- Check your current nomination. Log into your super fund and confirm whether you have a binding nomination, when it was last signed, and whether it has expired. Many people discover they have no valid nomination at all.
- Confirm your nominees are eligible. A nomination to someone who is not a SIS dependant is invalid — the trustee will disregard it and pay at its discretion.
- Assess the tax position. If your likely beneficiaries include adult children, model the tax cost and consider whether a recontribution strategy makes sense for your situation.
- Align your super nomination with your will. If you’re directing super to your estate, make sure your will is current and that the estate distribution reflects your wishes.
- Review after life changes. Marriage, divorce, the death of a nominated beneficiary, or a child reaching financial independence are all triggers to revisit your nomination.
