When you're suddenly the only trustee: the SMSF survivor's six-month window

The structural rules for self-managed super funds in Australia are simple and unforgiving. Under section 17A of the SIS Act, an SMSF must have either two or more individual trustees, or a corporate trustee. A single individual trustee is not permitted, with the narrow exception of a single-member fund using a corporate trustee. The structure is a continuing requirement: if the structure breaks at any point during the year, compliance breaks with it.

For most two-member couple SMSFs, the structure is straightforward — both spouses are individual trustees, and both are members. The arrangement works while both are alive. It stops working at the moment one of them dies.

What is the six-month window?

The six-month window. When a member of a two-member individual-trustee SMSF dies, the surviving member is left as a single individual trustee — a non-compliant structure. The SIS Act provides a transitional period: six months from the date of the structural breach to remediate to a compliant arrangement. During the six months, the fund continues to operate and remains a complying SMSF, but the structure must be fixed by the end of the period. If it is not, the fund loses complying status, with severe tax consequences (45% of the fund's market value, plus the loss of concessional treatment going forward).

Six months sounds like a generous window. In practice, the first 60 to 90 days after a spouse's death are absorbed by grief, family, funeral logistics, and the immediate practical demands of bereavement. The SMSF compliance clock runs quietly in the background. By the time the surviving spouse engages with the fund's affairs in earnest, half the window may already be gone.

What are the four restructuring paths?

Four restructuring paths. The surviving member has four practical options.

Corporate trustee with sole director. The fund's individual-trustee structure is replaced by a corporate trustee — a company that acts as trustee. The surviving member becomes the sole director and sole shareholder of the trustee company. Under SIS, a single-member SMSF with a corporate trustee where the sole member is the sole director is permitted. This is the simplest continuation path: the survivor retains the SMSF, retains control of investments, and retains the structure they may have spent decades building.

The mechanics involve incorporating a trustee company (typically $400–$600), amending the trust deed if required, and re-registering all SMSF assets in the new trustee company's name — share registries, bank accounts, property titles. Asset re-registration is the most administratively meaningful step; it is manageable but not trivial.

Appoint a new individual co-trustee. A second individual trustee — typically an adult child — is appointed. Under SIS, an individual trustee must generally be a member, so the new trustee also becomes a member of the fund. They may join with no current balance, or contribute, or roll over from another fund. This path involves the adult child in the SMSF as a member-trustee, which has implications for family dynamics and future succession of the fund. It is less commonly chosen than the corporate trustee path, but is appropriate where there is a genuine intention to bring an adult child into the fund.

Roll out to a public-offer fund and wind up the SMSF. The survivor's balance is rolled over to an industry, retail, or master fund product; the deceased's death benefit is paid (lump sum or pension to the survivor, in accordance with the BDBN and trust deed); the SMSF is then wound up. This is the simplest from a compliance perspective and is often appropriate where the survivor is not interested in continuing to manage an SMSF. A wind-up typically takes 3–6 months and involves $3,000–$10,000+ in professional fees, depending on the assets held.

Wind up with both balances leaving. Functionally similar to the rollout-and-wind-up, but emphasising the wind-up. The SMSF is closed; both balances find new homes (the survivor's via rollover, the deceased's via death benefit payment).

How should the survivor choose between the paths?

The choice in practice. The right path depends on the surviving spouse's circumstances.

The corporate trustee path is appropriate where the survivor wants to retain control of investments, the SMSF holds significant illiquid assets (property, unlisted investments) that would be costly or disruptive to liquidate, the survivor is comfortable with ongoing trustee duties, and the cost of running the fund justifies the benefit.

The wind-up path is appropriate where the survivor is not comfortable with trustee duties, the fund's assets can be readily liquidated and rolled over, the cost of running the fund (audit, accounting, ASIC fees) outweighs the benefit, or the survivor wants administrative simplicity above all.

There is an age dimension. Surviving spouses in their 80s and 90s often choose wind-up — the ongoing trustee responsibility is no longer appropriate at that life stage, and a public-offer fund handles the administration. Surviving spouses in their 60s and early 70s, particularly those who were active co-trustees during the marriage, more often choose continuation.

What if the survivor was only a trustee in name?

The "I was a trustee in name only" reality. Many SMSFs are run primarily by one spouse — typically the husband, particularly in older couples. The wife is a co-trustee in name and a co-member, but the day-to-day running of the fund — investment decisions, broker calls, attendance at audit meetings, year-end accounting reviews — has been the husband's domain. When the husband dies, the wife is suddenly the trustee of a fund she may never have actively managed.

For such surviving spouses, continuing the SMSF is a substantial new role. The corporate trustee path may technically work, but the question is whether the survivor wants the responsibility. Wind-up to a public-offer fund is often more honest about the survivor's actual capacity and inclination — and there is no shame in that choice. SMSFs are powerful structures, but they require active engagement.

How does death benefit administration run alongside the restructure?

The death benefit administration in parallel. Alongside the trustee restructure, the deceased's death benefit must be dealt with within the standard timing rules — generally six months from death, or three months from grant of probate, whichever is later, to preserve pension phase tax treatment during admin. The two timelines are aligned but not identical: the trustee restructure is about fund compliance; the death benefit administration is about tax treatment of the deceased member's interest.

A clean execution addresses both in the same period. The fund either continues with a corporate trustee (and the death benefit is paid as a reversionary or new pension to the survivor, or as a lump sum out of the fund), or the fund winds up (with the death benefit paid out as part of the wind-up).

What is the pre-emptive plan couples should make?

The pre-emptive plan. For couples currently in two-member individual-trustee SMSFs, the conversation to have now is the "if I die first" plan. Document what each spouse wants to happen — continue with corporate trustee, wind up to a specific public-offer fund — and communicate the plan. Consider switching to a corporate trustee structure now, while both are alive and engaged, removing the structural question from the future bereaved scenario altogether. Make sure the surviving spouse knows who to call: the adviser, the accountant, the SMSF auditor.

The six-month window is a real constraint, but it is not the hard part. The hard part is making the decision under grief. Making the decision in advance — calmly, together, with the time to think — is one of the kindest things SMSF couples can do for whichever of them is left behind.
