When an SMSF trustee dies, the ATO allows six months to restore the fund's trustee structure under SIS Act section 17A. If a trustee loses capacity, their legal personal representative may step in — if the enduring power of attorney and fund deed permit it. Pre-emptive steps — corporate trustee structure, a valid BDBN, and an appropriate EPOA — prevent a crisis.
If you have a self-managed super fund, here is a question worth sitting with: what happens to the fund when one of you dies or loses mental capacity?
For many SMSF trustees, the honest answer is that it has not been thought through in any structured way. That is exactly when crisis becomes the response — at the most difficult time in a family's life, with grieving or overwhelmed people improvising under pressure. Pre-emptive planning is straightforward to do while everyone is well and capable. It is very hard to do in the middle of a death or a dementia diagnosis.
Why is SMSF trustee succession different from APRA-regulated funds?
APRA-regulated funds — retail and industry super — are run by professional trustees. When a member dies, the fund continues regardless. Self-managed funds are different. They depend on active, capable trustees, and the members are the trustees. When a trustee dies, loses mental capacity, resigns, or becomes bankrupt, the fund's trustee structure fails to meet the requirements of the Superannuation Industry (Supervision) Act 1993 unless remedied. The compliance obligation does not pause while the family deals with grief.
The ATO allows a six-month period after a member's death for an SMSF to come back into compliance with the trustee requirements of section 17A of the SIS Act. Within that period, the surviving trustee or the deceased's legal personal representative must establish a valid trustee structure going forward — either by adding a replacement individual trustee, converting to a corporate trustee structure, or, if the fund no longer serves any purpose, commencing a wind-up. Six months sounds like a long time when everyone is well and nothing urgent is happening. It is a short time when the family is dealing with an estate, a funeral, and all the other administration that follows a death.
Should an SMSF use a corporate or individual trustee structure for succession planning?
One of the most consequential structural choices in an SMSF is whether to use individual trustees or a corporate trustee. For succession planning, the corporate trustee structure is significantly simpler.
With individual trustees, all assets of the fund must be held in the names of the trustees personally — bank accounts, shares, real estate, and other assets are registered in the names of the individual trustees in their capacity as trustees of the fund. Every time a trustee changes — through death, appointment of a replacement, or any other reason — the assets must be re-titled in the new trustee names. For real estate, this can involve stamp duty in some states. For other assets, it involves paperwork with every institution and counterparty. At the worst possible time for the family, there is an administrative workload that cannot be avoided.
With a corporate trustee structure, the company — not the individuals — holds the assets. Adding or removing directors, which is how trustee changes are handled in a corporate structure, does not trigger asset re-titling. The company remains the trustee and asset holder regardless of director changes. This is why many practitioners recommend that SMSFs for members approaching later life convert to corporate trustee structure, if they have not already done so. The conversion has a cost, but it simplifies everything that follows.
How does a binding death benefit nomination affect SMSF death benefit distribution?
When a member dies, their superannuation interest must be paid out as a death benefit — it cannot remain indefinitely in the fund. The distribution is either a lump sum or, where eligible, a pension to a surviving spouse or other dependant. The order in which this happens, and who receives what, depends critically on whether a valid binding death benefit nomination (BDBN) is in place.
A BDBN instructs the trustee (in a binding, not merely advisory, way) to pay the death benefit to specified beneficiaries in specified proportions. Under section 59 of the SIS Act and regulation 6.22 of the SISR, trustees must follow a valid BDBN. Without one, the surviving trustee or trustees exercise discretion among eligible dependants — which can create conflict in blended families or in situations where family members disagree about the appropriate distribution. For most SMSF members, having a valid, current BDBN in place removes this uncertainty.
BDBNs typically expire after three years unless the fund deed provides for non-lapsing nominations, which some deeds do. An SMSF member who set up a BDBN five years ago and has not reviewed it since should check whether it remains valid, and whether the nominated beneficiaries and proportions still reflect their intentions.
What happens to an SMSF when a trustee loses mental capacity?
Loss of mental capacity creates a different but equally important problem. A trustee must be capable of making decisions about the fund. A member who has lost cognitive capacity cannot continue as trustee, and the fund's trustee structure again fails to meet the SIS Act requirements.
Section 17A(3) of the SIS Act provides for the member's legal personal representative — which includes a person holding an enduring power of attorney — to be appointed as trustee in the member's place where the member lacks legal capacity. But this only works if the enduring power of attorney explicitly addresses SMSF trustee replacement, and if the fund deed permits the appointment. An enduring power of attorney that is silent on superannuation and SMSF matters may not, depending on its terms and the fund deed, authorise the attorney to step in as trustee. This is why, for SMSF members in later life, reviewing the EPOA terms and the fund deed for capacity-event scenarios is important while the member still has capacity.
The capacity scenario is harder to see coming than death. Cognitive decline can be gradual and ambiguous. Having the structural arrangements in place — the EPOA with appropriate scope, a fund deed that accommodates it, a corporate trustee structure where possible — means the fund can continue functioning even as a member's capacity reduces, without requiring a crisis decision in the middle of a difficult family situation.
Should the SMSF continue or be wound up after a trustee dies?
For SMSF members in later life, particularly after the death of a spouse, the succession event often prompts a genuine question: should the fund continue, or should it be wound up and the balance rolled into an APRA-regulated fund?
Continuation makes sense where a capable successor trustee can be established, the fund's assets and structure genuinely benefit from the SMSF arrangement, and the surviving member has the interest and capacity to manage the fund going forward. For a single surviving member with a reasonable balance, an SMSF continues to provide investment flexibility and cost-efficiency that may be hard to replicate elsewhere.
Wind-up makes sense where no suitable replacement trustee is available, the administrative burden is becoming difficult for the surviving member, or the fund's assets and circumstances no longer justify the SMSF structure. Wind-up is itself a process — the assets must be disposed of or transferred appropriately, the benefit paid, tax obligations finalised, and the fund formally deregistered with the ATO. It typically takes several months even when it goes smoothly, and benefits from coordinated input from the fund's accountant, financial adviser, and solicitor.
What pre-emptive steps should SMSF trustees take for succession planning?
The planning that prevents succession from becoming a crisis is not complicated. A corporate trustee structure (or transition to one) removes most of the asset re-titling burden from trustee changes. An up-to-date enduring power of attorney, with explicit coverage of SMSF trustee matters, provides for capacity events. A current, valid BDBN removes uncertainty about death benefit distribution. A documented succession plan — who does what, on what trigger, with what authority — means the family does not have to improvise. And a clear relationship with advisers who know the fund means coordinated help is available when it is needed most.
For SMSF members who are in good health and have not thought about any of this, the right time to address it is now.
Key takeaways
- APRA-regulated funds continue operating after a member's death or loss of capacity — professional trustees handle it. SMSF trustees are the members themselves, so a trustee death, loss of capacity, or resignation means the fund's trustee structure fails to meet section 17A of the SIS Act unless remedied. The ATO provides a six-month window after a member's death for the fund to come back into compliance.
- Corporate trustee structure significantly simplifies trustee succession. With individual trustees, every trustee change requires asset re-titling across bank accounts, shares, and real estate — which can trigger stamp duty for property in some states. With a corporate trustee, director changes don't require asset re-titling because the company (not the individuals) holds the assets. Converting to corporate trustee before a succession event is the most common practitioner recommendation for older SMSF members.
- A valid binding death benefit nomination (BDBN) removes uncertainty about death benefit distribution on the member's death. Without one, the surviving trustee exercises discretion among eligible dependants — which can create conflict in blended families. BDBNs typically expire after three years, so members should verify their nomination is current and still reflects their intentions.
- Loss of capacity requires advance planning because it is gradual and harder to predict than death. Section 17A(3) of the SIS Act allows a member's legal personal representative (including an attorney under an enduring power of attorney) to act as trustee — but only if the EPOA explicitly covers SMSF trustee matters and the fund deed permits the appointment. Neither is automatic.
- After a trustee dies, the surviving member must decide whether to continue the SMSF or wind it up. Continuation requires a capable successor trustee and ongoing willingness to manage the fund. Wind-up is often the better choice where no suitable trustee is available, the administrative burden is too great, or the fund's balance and circumstances no longer justify the costs and obligations of the SMSF structure.
Frequently asked questions
What happens to an SMSF when one trustee dies?
The fund's trustee structure fails to meet the requirements of section 17A of the SIS Act — which requires that every member is a trustee and every trustee is a member. The ATO allows a six-month window after a member's death for the fund to remedy the situation. Within that period, the surviving trustee or the deceased member's legal personal representative must establish a valid trustee structure: either by adding a replacement individual trustee, appointing the legal personal representative as trustee in the interim, converting to a corporate trustee, or commencing a wind-up if the fund no longer has a continuing purpose.
How does loss of mental capacity affect SMSF trustee requirements?
A trustee must be capable of making decisions about the fund. A member who has lost cognitive capacity cannot continue as trustee, and the fund again fails to meet section 17A requirements. Section 17A(3) of the SIS Act allows the member's legal personal representative — including a person holding an enduring power of attorney — to step in as trustee in the incapacitated member's place. But this only works if the enduring power of attorney explicitly addresses SMSF trustee matters and the fund deed permits the appointment. Neither is guaranteed unless planned for in advance.
Does a binding death benefit nomination expire in an SMSF?
Usually yes — BDBNs typically expire after three years under the standard SIS Act and Regulations framework. Some fund deeds provide for non-lapsing nominations, which do not expire; whether a fund deed includes this provision varies. An SMSF member who set up a BDBN some years ago should check whether it remains valid, whether the nominated beneficiaries and proportions still reflect their current intentions, and whether the deed provides for lapsing or non-lapsing nominations. An expired or poorly-structured BDBN can lead to the trustee exercising discretion in ways the deceased member would not have intended.
When should a surviving SMSF member wind up the fund rather than continue it?
Wind-up is worth considering when: there is no suitable replacement trustee available; the surviving member no longer has the interest, capacity, or confidence to manage the fund's investments and compliance obligations; the fund's balance has reduced to a point where SMSF costs are disproportionate; or the fund's assets are straightforward enough that an APRA-regulated fund with appropriate investment options would serve just as well. Wind-up itself takes several months — assets must be disposed of or transferred, the benefit paid, tax finalised, and the fund deregistered with the ATO. It is best approached with the help of the fund's accountant, financial adviser, and solicitor working together.
