Binding death benefit nominations and the 3-year expiry trap: keeping super nominations current

For Australian retirees who have made a binding death benefit nomination (BDBN) to direct where their superannuation goes when they die, the 3-year expiry rule is the most commonly overlooked feature of super estate planning. Under regulation 6.17A of the Superannuation Industry (Supervision) Regulations 1994 (the SIS Regulations), a standard BDBN made with an APRA-regulated fund (a retail or industry fund) lapses three years after it was signed, last confirmed or amended unless the member renews it — and once it lapses, the trustee's discretion is restored and the trustee may pay the death benefit to any of the member's superannuation dependants or to the estate, regardless of the original nomination. The practical consequence for many retirees is that they have no effective binding nomination at all: they signed one years ago, the 3-year mark passed unnoticed, and their carefully-considered intent has quietly converted into trustee discretion — with potentially large tax consequences if the super then passes to a non-dependant.

The standard BDBN framework under regulation 6.17A sets specific requirements: the nomination must be in writing, signed and dated by the member in the presence of two adult witnesses neither of whom is named as a beneficiary, and given to the trustee. It can nominate one or more beneficiaries — each of whom must be a superannuation dependant under the SIS Act (a spouse, a child of any age, a person in an interdependency relationship, or someone financially dependent on the member) or the legal personal representative of the estate — and the proportions each is to receive. Once validly made, it binds the trustee for three years from signing, and then ceases to bind. The expiry applies whether or not the member's circumstances have changed, whether or not they intended the nomination to be permanent, and whether or not they are even aware it has lapsed.

The SMSF position is different, and this is a distinction worth getting right. Section 59 of the SIS Act and regulation 6.17A do not apply to self-managed super funds — the ATO confirmed in Self Managed Superannuation Funds Determination SMSFD 2008/3 that an SMSF's governing rules may permit binding nominations that do not follow regulation 6.17A at all. So an SMSF BDBN need not lapse after three years and need not use two witnesses, if the trust deed allows — meaning an SMSF with a modern deed can have a non-lapsing nomination that continues until the member changes it. The catch is that the SMSF deed must genuinely support it and the nomination must be made strictly in accordance with the deed's terms; a deed that hasn't been updated may still impose lapsing or witnessing conditions. Some retail and industry funds also offer non-lapsing nominations as a feature. Where a non-lapsing nomination is available and properly made, it removes the renewal-discipline problem entirely.

The consequences of a lapsed BDBN turn on how the trustee exercises its restored discretion. The trustee must work out who, among the deceased's superannuation dependants and the estate, should receive the benefit — typically by inviting claims, considering any non-binding nomination or expressed wishes, weighing each potential beneficiary's relationship and financial circumstances, and then deciding. In a straightforward family (one long marriage, adult children on good terms) the result may match what the member would have chosen, though the claim process, delay and cost still bite. In a complex family — a second marriage, estranged or blended children, a recent relationship change — trustee discretion can produce an outcome quite different from the member's actual wishes.

A reversionary pension nomination is a related but more durable mechanism, and it is not subject to the 3-year rule. Where a retiree is drawing an account-based pension, they can attach a reversionary nomination — usually to their spouse — so that on death the pension simply continues ("reverts") to that person, with the income stream running on without interruption. A reversionary nomination attached at commencement generally continues until the reversionary dies or a specific revocation event occurs; it does not expire the way a standard BDBN does. For couples with substantial pension balances, attaching a reversionary nomination to each account-based pension is often the most reliable estate-planning step, because it needs no renewal. Most fund deeds give the reversionary nomination priority for that pension, with any BDBN covering whatever remains in accumulation.

The tax stakes are what make all of this matter, especially where the likely recipient is a non-dependant. A death benefit lump sum paid to a death benefits dependant — broadly a spouse or former spouse, a child under 18, a person in an interdependency relationship, or someone who was financially dependent — is entirely tax-free, whether it contains a taxed or untaxed element. A lump sum paid to a non-dependant — most commonly an adult child who is not financially dependent — has its tax-free component pass tax-free, but the taxable component is assessable, with a tax offset capping the rate on the taxed element at 15% (effectively about 17% with the 2% Medicare levy) and on any untaxed element at 30% (about 32%). On a $500,000 benefit with a $400,000 taxed element going to an adult child, that is roughly $68,000 of tax — versus zero to a tax-dependant. A lapsed BDBN that throws the decision to trustee discretion can land the benefit with a recipient the member wouldn't have chosen, and a recontribution strategy to convert taxable component into tax-free component is often worth considering alongside. Note that an adult child with a disability is not automatically a dependant — they qualify only through the financial-dependency or interdependency tests.

What do worked planning examples show?

These two cases show how the BDBN expiry trap operates in practice. Illustrative only — not personal advice — using FY25-26 figures.

Case 1 — Anne, 72, a retired widow with two adult children and an $850,000 balance in an industry fund, drawing an account-based pension that began four years ago. She signed a BDBN nominating her two children equally when she started the pension and assumes it is "in place". On these facts the BDBN lapsed about a year ago, because an industry-fund BDBN lapses three years after signing. If Anne died now, the trustee would have discretion. Her children are non-dependants, so the lump-sum tax applies regardless of who receives it — roughly $145,000 if the $850,000 is almost entirely taxable component (about 17%) — but the recipients and proportions are now up to the trustee, which may or may not match her intent. On these facts the rational steps are to renew the BDBN immediately, set a reminder around the 30-month mark for the next renewal, and check whether her fund offers a non-lapsing nomination (and switch if it suits). A recontribution strategy to convert taxable component to tax-free could meaningfully cut her children's eventual tax bill.

Case 2 — Tom, 80, and Mary, 78, married 50 years. Tom has an account-based pension of $1.2M with a reversionary nomination to Mary made seven years ago, plus a BDBN signed at the same time nominating Mary 100%. Mary has $400,000 in accumulation. On these facts the reversionary nomination is the key protection: it is not subject to the 3-year lapse, so Tom's pension continues automatically to Mary on his death regardless of the BDBN's status. The BDBN itself lapsed about four years ago, so for any accumulation balance Tom holds the trustee's discretion is restored — but since Tom's super is all in the pension with little or no accumulation, the practical impact is small. On these facts the rational steps are to confirm with the fund that the reversionary nomination is recorded and effective, renew the BDBN to catch any stray accumulation (such as earnings credited during the year), and make sure Mary's own super carries a current nomination so her $400,000 is covered if she dies first. The reversionary nomination is the primary safeguard; the BDBN is the backstop.

For retirees with substantial super, the BDBN expiry trap is one of the cleanest examples of an estate-planning measure that fails silently. The advice work is to check the current status of every BDBN at each annual review, diarise renewals rather than relying on the fund to remind you, use a non-lapsing nomination where one is genuinely available (an SMSF with a suitable deed, or a fund that offers the feature), attach reversionary nominations to pension streams as the more durable mechanism, and keep the nomination consistent with the will and powers of attorney. Far too often a member's super — a large share of family wealth — passes under trustee discretion not by any deliberate choice but because a nomination lapsed without anyone noticing. Annual verification is the cure.
