SMSF Death Benefits and Binding Nominations — What Every Trustee Needs in Place

Most people assume their will decides who gets their money when they die. For superannuation, that's usually wrong. Super sits outside your estate, and under most SMSF trust deeds, the trustee decides who receives your death benefit — unless you've put a valid binding death benefit nomination (BDBN) in place. For an SMSF, where you or your family members are often the trustees yourselves, getting this wrong can leave a spouse, child, or business partner with unexpected power over a large sum of money at the worst possible time.

Why Super Isn't Covered by Your Will

Superannuation is held in trust, not personally owned in the same way as your house, car, or bank account. That means it doesn't automatically form part of your deceased estate, and a will has no direct authority over it. Instead, the SMSF's trust deed sets out how a death benefit is to be dealt with — and in most deeds, that means the surviving trustee(s) get discretion over who receives it, unless you've overridden that discretion with a valid direction.

This is a genuinely important distinction for SMSF trustees, because in a small fund it's often family members — a spouse, adult children, or a business partner — who end up making that discretionary decision. Without clear direction from you in advance, that discretion can become a source of real conflict.

What a BDBN Actually Does

A binding death benefit nomination (BDBN) is a written direction to your fund's trustee, specifying exactly who should receive your super death benefit and in what proportions. When a BDBN is valid, it removes the trustee's discretion entirely — they're legally required to pay your benefit according to your instructions, not their own judgement.

To be valid, a BDBN generally needs to:

• Be in writing, signed and dated by the member
• Be witnessed by two people who are not nominated beneficiaries
• Nominate only people who are valid dependants, or your legal personal representative
• Comply with the specific requirements set out in your fund's trust deed

Because SMSF trust deeds vary, a BDBN that's valid for one fund's deed might not be valid for another's — this isn't a form you can copy from a friend's fund.

Non-Lapsing vs Lapsing Nominations

Historically, binding nominations were widely understood to expire — or "lapse" — every three years unless renewed, a rule that traces back to APRA-regulated super fund requirements. Many trustees have been caught out by an old nomination quietly expiring without them realising.

A 2022 High Court ruling clarified an important distinction for SMSFs specifically: unlike APRA-regulated funds, SMSF binding nominations do not need to expire after three years as a matter of law. You can make a nomination non-lapsing — permanent until you change it — but only if your fund's trust deed actually allows for non-lapsing nominations. Older deeds, or deeds not updated since the ruling, may still impose the three-year lapsing rule by their own terms.

This makes it worth checking your trust deed specifically, rather than assuming the general SMSF rule applies automatically to your fund.

Who You Can Nominate

You can generally nominate:

• Dependants — your spouse or de facto partner, your children (of any age, though tax treatment differs for adult children), financial dependants, or someone in an interdependency relationship with you
• Your legal personal representative — meaning the benefit is paid to your deceased estate and then distributed according to the terms of your will

Nominating your legal personal representative is often used deliberately, precisely so that the flexibility of a well-drafted will — including testamentary trusts — can be used to control how the benefit is ultimately distributed, rather than paying it directly and immediately to a dependant.

Why It Must Fit Your Broader Estate Plan

A BDBN shouldn't be prepared in isolation from your will and broader estate plan — the two need to work together. Some situations where this really matters:

• Blended families. Without coordination, a BDBN naming a current spouse directly could unintentionally exclude children from a previous relationship, even if your will tries to provide for them.
• Testamentary trusts. If you want a death benefit to flow into a testamentary trust for tax or asset protection reasons, you generally need to nominate your legal personal representative, not a dependant directly.
• Adult children. Financially independent adult children are usually not tax-free recipients of a death benefit (see the tax section below), which can influence whether it's more efficient to direct the benefit through your estate.
• Asset protection. Paying a benefit directly to a dependant exposes it to that person's own creditors or relationship breakdown risk; routing it through a trust structure can offer more protection.

This is genuinely specialist territory — a BDBN drafted without reference to your will can actively work against your broader intentions.

What Happens With No Valid BDBN

If you die without a valid BDBN in place, the surviving trustee(s) of your SMSF have discretion over who receives your death benefit and in what proportions, within the bounds of who's eligible under super law. In a single-member fund with an individual trustee structure, this could mean a co-trustee you appointed years ago — who may or may not still reflect your current wishes — makes that call.

This is a common source of family disputes, particularly in blended families, second marriages, or where a surviving trustee has their own competing financial interest in how the benefit is distributed. It can end up in the courts, with legal costs eroding the very benefit being disputed over.

Practical Steps to Get It Right

• Check whether your fund's trust deed allows non-lapsing BDBNs, and update the deed if it doesn't
• Have a specialist SMSF or estate planning lawyer draft your BDBN — avoid generic online templates
• Coordinate your BDBN with your will, especially if testamentary trusts or blended family considerations apply
• Review your BDBN after every major life event: marriage, divorce, a new child, or the death of a nominated beneficiary
• Check what happens to your role as trustee or director when you die, especially in a single-member fund — who takes over, and is that person prepared for the responsibility
• Keep a signed, witnessed copy of your BDBN with your fund's records, not just with your personal papers

Death Benefits Tax Treatment

How your death benefit is taxed depends heavily on who receives it:

This tax gap between dependants and non-dependants is one of the key reasons a BDBN needs to be considered alongside broader estate and tax planning, not decided in isolation.

Frequently Asked Questions

Does my will control who gets my SMSF super?

Not automatically. Super sits outside your estate, and under most SMSF trust deeds, the trustee decides who receives your death benefit unless you have a valid binding death benefit nomination in place.

Do SMSF nominations expire every 3 years?

Not necessarily. A 2022 High Court ruling confirmed SMSF binding nominations, unlike APRA-regulated fund nominations, don't have to lapse after three years — but your trust deed needs to specifically allow for a non-lapsing nomination.

Who can I nominate to receive my death benefit?

You can nominate dependants (spouse, children, financial dependants, or someone in an interdependency relationship) or your legal personal representative, so the benefit is paid to your estate and dealt with under your will.
