When someone dies, their superannuation does not automatically form part of their estate. It is paid as a death benefit to their dependants, their nominated beneficiaries, or their legal personal representative — and how much tax applies depends almost entirely on who receives it. For a spouse or young child, a lump sum death benefit is usually completely tax-free. For an adult child, the same payment can lose up to 17% to tax, or 32% on some components.
Understanding these rules matters twice over: for anyone planning their own super nominations, and for anyone who has just lost someone and is trying to work out what will actually arrive. This guide explains who counts as a tax dependant, the tax rates for lump sums and income streams, and the planning steps that can legally reduce the tax. Figures are current for 2026-27. This is general information, not personal financial advice.
Two Definitions of “Dependant” — and Why the Difference Matters
The first thing to grasp is that super law and tax law define “dependant” differently, and the tax definition is the one that decides the tax bill.
Under superannuation law, a dependant includes your spouse or de facto partner, your children of any age, anyone in an interdependency relationship with you, and anyone financially dependent on you. Your super fund can pay a death benefit directly to any of these people.
Under tax law, a “death benefits dependant” (tax dependant) is narrower. It includes:
- Your current or former spouse or de facto partner (of any sex)
- Your children under 18
- Anyone in an interdependency relationship with you
- Anyone else who was financially dependent on you at the time of your death
The critical difference is adult children. A 30-year-old daughter is a dependant under super law, so the fund can pay her directly — but she is not a tax dependant, so the taxable component of her payment is taxed. The same applies to a financially independent parent or sibling. Many families discover this distinction only after a death, when the tax bill arrives.
If the benefit is paid to the deceased’s estate instead, the estate pays tax based on who ultimately receives the benefit — and the Medicare levy does not apply to payments made through the estate. This can change the arithmetic, so executors should get advice before distributing super through a will.
How a Super Balance Is Broken Into Components
Every super balance is made up of up to three tax components, and each is taxed differently when paid as a death benefit:
| Component | What it is | How it is taxed for a non-dependant |
|---|---|---|
| Tax-free component | After-tax (non-concessional) contributions and certain other amounts | 0% — always tax-free, for anyone |
| Taxable component — taxed element | Employer contributions, salary sacrifice, and investment earnings — the bulk of most balances | 15% + 2% Medicare levy |
| Taxable component — untaxed element | Benefits from untaxed super funds, mainly some public-sector defined benefit schemes | 30% + 2% Medicare levy |
The tax-free component is never taxed, whoever receives it. That is why the mix of components inside a balance matters so much: two people with identical $400,000 balances can leave very different after-tax amounts depending on how much of each balance is tax-free. You can find your own component split on your super fund statement or member portal — it is worth checking, because after-tax contributions you make during your lifetime increase the tax-free component.
Tax on Lump Sums: Dependants vs Non-Dependants
A non-dependant can only receive a death benefit as a lump sum — income streams are not available to them. A tax dependant can choose a lump sum or, in some circumstances, an income stream. The lump sum rules are:
| Recipient | Tax-free component | Taxable component (taxed element) | Taxable component (untaxed element) |
|---|---|---|---|
| Tax dependant | 0% | 0% | 0% |
| Non-dependant | 0% | 15% + 2% Medicare levy | 30% + 2% Medicare levy |
For a tax dependant receiving a lump sum, the whole payment is tax-free — it is not assessable income and does not even need to be declared. For a non-dependant, the fund generally withholds the tax before paying out, so the amount received is the after-tax figure.
Worked Example: A $400,000 Balance Left to an Adult Child
Consider Margaret, who dies with a $400,000 super balance: a $50,000 tax-free component and a $350,000 taxable component (taxed element). She leaves it to her 35-year-old son, David, who is financially independent and therefore not a tax dependant.
| Component | Amount | Tax rate | Tax |
|---|---|---|---|
| Tax-free component | $50,000 | 0% | $0 |
| Taxable component (taxed element) | $350,000 | 15% + 2% Medicare levy | $59,500 |
| Total | $400,000 | $59,500 |
David receives $340,500. The $59,500 tax is withheld by the fund — 15% tax ($52,500) plus the 2% Medicare levy ($7,000) on the $350,000 taxable component. Had Margaret left the same $400,000 to her spouse, the spouse would have received the full $400,000 tax-free as a lump sum. The difference — $59,500 — is entirely due to who the beneficiary is.
Now consider a balance with an untaxed element. James dies with $300,000 in an untaxed public-sector scheme: $30,000 tax-free, $240,000 taxable (taxed element) and $30,000 taxable (untaxed element), left to his adult daughter:
| Component | Amount | Tax rate | Tax |
|---|---|---|---|
| Tax-free component | $30,000 | 0% | $0 |
| Taxable (taxed element) | $240,000 | 15% + 2% Medicare levy | $40,800 |
| Taxable (untaxed element) | $30,000 | 30% + 2% Medicare levy | $9,600 |
| Total | $300,000 | $50,400 |
James’s daughter receives $249,600. The untaxed element is the expensive part: 32% of it goes to tax, compared with 17% for the taxed element. Untaxed elements are uncommon — they arise mainly in older public-sector defined benefit funds — but if your fund has one, it is worth knowing about.
Death Benefit Income Streams for Dependants
A tax dependant who is eligible can also receive the benefit as an income stream — for example, a reversionary pension where the deceased was already drawing an account-based pension. The tax treatment of an income stream depends on the ages of the deceased and the beneficiary:
- Deceased was 60 or older, or beneficiary is 60 or older: the taxed element of the taxable component is tax-free. The untaxed element is taxed at the beneficiary’s marginal rates with a 10% tax offset.
- Both deceased and beneficiary under 60: the taxed element is taxed at the beneficiary’s marginal rates with a 15% tax offset. The untaxed element is taxed at marginal rates with no offset.
- Tax-free component: always tax-free, in any payment form.
Children under 18 who receive a death benefit income stream face extra rules: generally the pension must be commuted to a lump sum (and paid tax-free, as they are tax dependants) once they turn 25, unless they are permanently disabled. Child pensions also have special tax treatment, so specialist advice is essential.
Because an income stream spreads payments over years, it can be more tax-efficient than a lump sum for a dependant beneficiary — but it also locks the money into pension rules. The right choice depends on the beneficiary’s age, income and needs.
How the Benefit Is Paid: Binding Nominations and Discretion
Tax is only part of the story. Who actually receives your super depends on your nomination — and a nomination that has lapsed or was never made can send your super somewhere you did not intend.
- Binding death benefit nomination: Directs the fund trustee to pay the people you name, in the proportions you specify. Most binding nominations lapse after three years and must be renewed — check the expiry date on yours.
- Non-binding nomination: A statement of your wishes. The trustee must consider it but is not bound by it and may pay someone else.
- Reversionary beneficiary nomination: For account-based pensions, this automatically continues the pension to your nominated dependant on your death.
- No nomination: The trustee uses its discretion, paying your dependants or your estate according to the fund’s rules and super law.
- Paid to the estate: If the benefit goes to your legal personal representative, it is distributed under your will. Tax is then assessed on the ultimate beneficiaries, and the Medicare levy does not apply to the payment through the estate.
The ATO recommends reviewing your nomination at least once a year and after every major life event — marriage, divorce, the birth of a child, or a child turning 18. A nomination made when your children were young may no longer reflect your wishes, or the tax outcome, once they are adults.
Can You Reduce Death Benefit Tax?
There are legitimate strategies that can reduce the tax on a death benefit, but they need to be put in place during your lifetime:
- Make after-tax (non-concessional) contributions. Every dollar contributed after tax increases the tax-free component of your balance, and that component is never taxed on death. The non-concessional cap is $120,000 a year for 2025-26, with a three-year bring-forward rule of up to $360,000 for eligible members under 75.
- Withdraw and recontribute. Once you reach preservation age and retire (or turn 65), you can withdraw super tax-free and recontribute it as a non-concessional contribution, converting taxable component into tax-free component. This “recontribution strategy” is a well-established planning technique, but it has caps, eligibility conditions and timing rules — get licensed advice first.
- Review who you nominate. Leaving super to a tax dependant (a spouse, a child under 18, or a financial dependant) rather than an adult child can save 15% to 30% of the taxable component. This must be balanced against your actual wishes — tax should inform the decision, not dictate it.
- Consider your spouse first. A spouse who receives your super tax-free can then pass it on under their own estate plan. Leaving super to a spouse rather than directly to adult children is often the most tax-efficient path, though family circumstances vary.
- Keep insurance inside super in mind. Life insurance held through super is paid as part of the death benefit and taxed under the same rules. The proceeds form part of the taxable component, so a large insurance payout to a non-dependant can generate a large tax bill.
None of these strategies should be attempted without advice. The contribution caps, bring-forward rules and preservation conditions have real traps, and a mistake can trigger excess-contributions tax that wipes out the benefit.
What Beneficiaries Should Do After a Death
- Notify the super fund and provide a certified copy of the death certificate. Ask for the death benefit claim forms and a statement of the account’s tax components.
- Check the nomination. Find out whether there is a binding nomination and who it names. If you are a dependant but were not nominated, you can still make a claim — the trustee must consider all potential beneficiaries.
- Get the component breakdown in writing. You need to know the tax-free, taxed and untaxed amounts before you can work out the tax.
- Decide lump sum versus income stream (dependants only), considering your age, income and whether you need ongoing payments.
- Ask the fund to confirm the tax withholding before payment, so there are no surprises.
- Talk to a tax adviser or financial adviser if the balance is large, includes an untaxed element, or is being paid through an estate.
Super funds must pay death benefits as soon as practicable after the death, but complex claims — multiple potential beneficiaries, disputes, or missing nominations — can take months. Keep copies of everything you send and receive.
Frequently Asked Questions
Does a spouse pay tax on a super death benefit?
No. A spouse (or de facto partner) is a tax dependant, so a lump sum death benefit is entirely tax-free, including the taxable component. There is no limit on the amount.
Does an adult child pay tax on inherited super?
Yes, on the taxable component. The taxed element is taxed at 15% plus the 2% Medicare levy, and any untaxed element at 30% plus the levy. The tax-free component is not taxed. The fund usually withholds the tax before paying the balance.
Is the tax-free component of super taxed on death?
Never. The tax-free component — mainly after-tax contributions — is paid tax-free to any beneficiary, dependant or not, in any payment form.
What is the difference between a tax dependant and a super dependant?
A super dependant includes children of any age; a tax dependant includes only children under 18 (plus spouses, interdependency relationships and financial dependants). An adult child can receive super directly but still pays tax on the taxable component.
Can a non-dependant receive a super death benefit as a pension?
No. Non-dependants can only receive a lump sum. Only tax dependants can receive a death benefit income stream.
Is super included in the deceased’s estate for tax?
Not automatically. Super is held by the fund trustee and paid under super law. It only becomes part of the estate if it is paid to the deceased’s legal personal representative, in which case it is distributed under the will and taxed on the ultimate beneficiaries.
The Bottom Line
Super death benefit tax comes down to two questions: who receives the benefit, and what is inside the balance. Tax dependants — spouses, children under 18, interdependency partners and financial dependants — receive lump sums completely tax-free. Non-dependants, most commonly adult children, pay 15% plus the Medicare levy on the taxed element and 30% plus the levy on any untaxed element, while the tax-free component is never taxed.
For anyone with a significant super balance and adult children as beneficiaries, that 17% or 32% can amount to tens of thousands of dollars — which is why nominations and contribution strategies deserve attention while you are alive, not after.
