Death Benefits and Binding Death Benefit Nominations: What Trustees Need to Know

Death benefit disputes are messy because two separate legal systems collide. Probate deals with the estate. Super deals with trust law, the Superannuation Industry (Supervision) Act 1993, and the fund's own rules. The person who holds the chequebook for the super balance is the trustee, whether that is an APRA-regulated fund's board or the members of a self-managed super fund. That trustee must pay the death benefit to eligible recipients under super law. A clause in the member's will saying "divide everything equally among the children" does not, by itself, move super anywhere.

Who can be paid, how binding death benefit nominations (BDBNs) interact with trustee discretion, lapsing rules, and reversionary pensions: that is what trustees get wrong in practice. General information only. For member-focused context see why your will does not control super and how relationship breakdown can change who you want as beneficiary.

Who the trustee can pay

Super law limits death benefit recipients to dependants and the member's legal personal representative (LPR), usually the executor of the estate. Dependants include a spouse or de facto partner, children of any age, anyone financially dependent on the member at death, and anyone in an interdependency relationship with the member. That definition is narrower than everyday language. A sibling, friend, or adult child who was not financially dependent is not a dependant for direct super payment.

Nominating the LPR sends the benefit to the estate. The will then decides distribution, which allows gifts to non-dependants, but probate adds time and cost, and tax on the taxable component still follows super tax rules when the ultimate recipient is a non-dependant. In blended families, payment to the estate can also attract family provision claims in some states: a child left out of the will may challenge the estate even when super arrived legitimately through a valid LPR nomination. Nominating a dependant directly keeps the money outside the estate and usually simplifies tax for spouses and dependent children.

Invalid nominations create the hardest trustee decisions. Nominate a brother who is not a dependant? The nomination fails. The trustee must exercise discretion among eligible recipients, documenting who was considered and why. That discretion is exactly where family fights start.

Binding, non-binding, and non-lapsing nominations

A non-binding nomination expresses the member's wish. The trustee must consider it but may pay another eligible beneficiary if circumstances warrant. Most APRA-regulated funds use this model and cannot offer non-lapsing BDBNs. Members in those funds still face the same three-year renewal cycle on binding nominations.

A binding death benefit nomination removes discretion when it is valid. The trustee must pay as directed. Standard BDBNs under the Superannuation Industry (Supervision) Regulations 1994 must be signed and dated in writing, witnessed by two adults who are not beneficiaries, and renewed at least every three years. Miss the renewal and the binding nomination lapses. The member may still be alive and competent; the paperwork simply expired. Plenty of estate plans fail on that calendar detail alone.

Non-lapsing BDBNs are common in SMSFs whose trust deeds expressly allow them. Properly made, they stay in force until revoked or replaced. That removes the three-year treadmill but shifts responsibility to the member to update the nomination when life changes: new partner, estranged children, divorce and splitting orders, or a reversionary pension that should take precedence. The deed must authorise non-lapsing nominations. A form that looks binding but contradicts the deed is worthless.

Reversionary pensions and BDBNs

A reversionary pension is not a BDBN. Read the deed first. Some deeds say the reversionary pension interest prevails; others are silent or poorly drafted, and practitioners then argue about which document controls. Do not assume.

Where the pension commutation authority and deed support it, an account-based pension can continue to a named reversionary beneficiary (commonly a spouse) on death. For many couples that is the cleanest outcome: income continues, and a spouse reversionary pension is generally tax-free to the surviving spouse. A BDBN directing a lump sum to adult children can conflict with a reversionary pension to a spouse. Resolve that conflict before paying anyone, with legal advice if the deed is ambiguous. See SMSF pension rules for pension documentation expectations.

What SMSF trustees should document

The step that actually blows up is paying against an expired BDBN while a current reversionary pension sits in the file drawer. Trustees find a nomination signed four years ago, assume it still binds, and only later discover the three-year clock lapsed or the pension commutation authority names someone else entirely.

Before any payment, locate the current trust deed and every amendment touching death benefits. Match that against all BDBNs, non-binding nominations, pension documents, and reversionary forms. Confirm the death certificate, identify eligible dependants, and minuted a trustee meeting that records what was reviewed and why the chosen payment method follows the deed. If discretion applies because no valid binding nomination exists, the minutes need reasons, not boilerplate. Pay as soon as practicable once identity, eligibility, and tax components are confirmed, and keep everything for the annual audit.

Auditors ask about this when a member has died during the year. Thin minutes and a missing deed version are harder to fix after the money has left the fund.

Death benefit tax: taxed and untaxed elements

Tax follows the recipient and the components inside the benefit. Spouses and dependent children generally receive tax-free death benefits. Adult non-dependant children pay tax on the taxable component, and SMSF trustees need to split that component further.

Recipient type	Tax-free component	Taxable component: taxed element	Taxable component: untaxed element
Spouse or de facto partner	Tax-free	Tax-free	Tax-free
Child under 18	Tax-free	Tax-free	Tax-free
Financial dependant / interdependent	Tax-free	Tax-free	Tax-free
Adult child (non-dependant)	Tax-free	15% + Medicare levy	30% + Medicare levy
Estate, then non-dependant beneficiary	Follows ultimate recipient	15% + Medicare levy on taxed element	30% + Medicare levy on untaxed element

Most accumulation balances are mostly taxed element. Older defined benefit interests and some long-running SMSFs still carry meaningful untaxed element. On a $600,000 benefit that is 85% taxable with half untaxed element, an adult non-dependant child pays a very different bill than the 15% headline suggests. Confirm taxed and untaxed splits on the member's tax statement before paying. The ATO publishes death benefit tax guidance; do not rely on a blog table for a live payment.
