Binding Death Benefit Nominations Explained

Brad Dickfos • June 13, 2025

When it comes to superannuation, many people assume that their retirement savings will go to their loved ones when they pass away. Sadly, this isn’t always the case. Unlike other assets that are covered by your will, your superannuation is handled separately, and if you want to ensure it goes to who you want, you need a binding death benefit nomination (BDBN).


What is a binding death benefit nomination?

A BDBN is a formal instruction you give to your superannuation fund, telling them who should receive your super when you die. The fund must follow your instructions if your nomination is valid. This gives you certainty that your money will go to who you want.


If you don’t have a binding nomination, your super fund will decide who gets your money. This means your super could be distributed differently from what you intended. Without a valid nomination, your fund will usually follow set rules and laws about dependants.


The three-year expiry rule

A BDBN generally expires every three years. This means you need to renew it regularly to keep it valid. If your nomination expires and you haven’t updated it, your super fund will decide who gets your money when you pass away.


To avoid this, many people set reminders to review their nomination every few years. Major life events such as marriage, divorce, or having children are also opportune times to review your BDBN.


Non-lapsing binding nominations

Some super funds offer non-lapsing binding nominations, which do not expire. Once you make a valid non-lapsing nomination, it remains in place unless you choose to change or cancel it.

However, not all super funds offer this option, and each fund has its own rules about how non-lapsing nominations work. It’s important to check with your fund to see if you can make one and whether any conditions apply.


Binding nominations in SMSFs

If you have a self-managed super fund (SMSF), the rules around BDBNs can be different. Unlike large super funds, where trustee discretion is limited by the rules of the fund and superannuation laws, SMSFs can have more flexibility.


Some key differences include:

  • No automatic expiry: In many SMSFs, binding nominations do not expire unless the trust deed specifically states otherwise. This is different from retail and industry super funds, where nominations often expire after three years.
  • Customised rules: The rules about binding nominations in an SMSF depend on the trust deed, which is the legal document that governs the fund. Many SMSFs allow non-lapsing nominations, while others may require regular updates. Also, some SMSFs allow cascading nominations ie, instructing the fund to pay a death benefit to a secondary beneficiary if the primary beneficiary predeceases the member.
  • Trustee control: Since SMSF trustees are usually fund members themselves, there can be potential conflicts of interest when deciding how to distribute super benefits. A well-structured binding nomination can help prevent disputes among family members.


If you have an SMSF, it’s crucial to check your trust deed and ensure your nomination aligns with the fund’s rules.


Who can you nominate?

When making a binding nomination, you can’t just choose anyone – you must nominate one or more ‘eligible beneficiaries’. These include your:

  • Spouse (including de facto and same sex partners)
  • Children (including adopted or stepchildren)
  • Financial dependants (such as someone who relies on you financially)
  • Interdependents – someone you share an interdependent relationship with (such as a person you live with, have a close bond with, and where one or both of you provide financial assistance, domestic support, and personal care)
  • Legal personal representative (your estate, so your super is distributed according to your will)


If you nominate someone who isn’t eligible, your nomination will be considered invalid, and the super fund trustee will decide who receives your super.


How to make a valid binding nomination

To ensure your nomination is legally binding, follow these steps:

1.      Check your fund’s rules: different funds have different requirements for binding nominations.

2.      Complete the required form: your super fund will have a specific binding nomination form you need to fill out.

3.      Nominate a dependant or legal personal representative

4.      Ensure the proportions add up to 100%

5.      Sign and date it in the presence of two independent witnesses (over 18 and not beneficiaries)

6.      Submit the completed form to your super fund.


Final thoughts

A BDBN is an essential tool for ensuring your superannuation is distributed according to your wishes. If you don’t have one in place, or if yours has expired, your super fund may decide who gets your money – and it might not be who you intended.


Whether you choose a standard nomination with a three-year expiry, a non-lapsing nomination, or an SMSF-specific arrangement, keeping your nomination up to date is key. Take the time to review your super fund’s rules and ensure your hard-earned super goes to the ones you love.

There is much in the media about how the 50% capital gains tax (CGT) discount has contributed to the housing affordability problem in Australia (although no doubt the problem is a lot more complex than attributing it mainly to any taxation measure or measures).

Most of us keep a close eye on our bank accounts. But superannuation can be easier to lose track of, especially if you’ve changed jobs, moved house, changed your name, or simply set up a new fund and assumed everything followed you. That’s why the Australian Taxation Office (ATO) has issued a timely reminder. There is now $18.9 billion in lost and unclaimed super sitting across Australia. That’s up $1.1 billion since 2024 and spread across just under 7.3 million accounts. In other words, a lot of Australians have retirement savings that aren’t currently working for them and some of it could be yours. What “lost” or “unclaimed” super actually means Super doesn’t vanish, but it can go missing from your radar. It typically happens when an account becomes inactive and your super fund can’t contact you, or when you end up with multiple funds over the years. The ATO also holds certain amounts of super on behalf of individuals, for example, small inactive balances that have been transferred to the ATO, or other unclaimed amounts. The average amount of lost or unclaimed super is around $2,590 per person. That might not sound life-changing today, but over time it can grow into tens of thousands by retirement. A special note if you have an SMSF If you have an SMSF, this ATO update is particularly worth paying attention to. When you established your SMSF, you might have transferred most of your super across, but kept some behind, for example, to retain insurance cover through another fund. That means there could still be older super accounts from past jobs or retail/industry funds sitting in your name. The ATO is urging SMSF members to do a check, because a share of the $18.9 billion in lost and unclaimed super might be yours and could be rolled into your SMSF. One important practical tip is that if you locate lost super and want to move it into your SMSF, but your SMSF doesn’t show up as a transfer option in ATO online services, it’s often due to the fund’s compliance status. Take a moment to confirm your SMSF is listed as “complying” or “registered” on Super Fund Lookup. How to check for lost super (it only takes minutes) The ATO has made this super simple (pun intended!). You can: 1. Log in to myGov and go to ATO online services 2. Navigate to the Super section to view: Super held by the ATO Any lost or unclaimed accounts 3. Request a transfer to an eligible super account. Even if you don’t find anything, you’ll at least know everything is where it should be. Simple habits that help you stay on top of super Finding lost super is great but preventing it from happening at all is even better. A few easy habits can make a big difference: Keep your details up to date with your fund and the ATO so you stay contactable. Check whether you’ve got more than one account. Multiple accounts can mean multiple fees and duplicated insurance Consider consolidating if it suits your situation. Fewer accounts can mean lower fees and easier management but just be sure to check any insurance you might lose before rolling over Read your annual statement. It’s a quick way to confirm contributions, fees, returns, investment mix and beneficiaries. Why acting now matters Since 2022, the ATO has already reunited Australians with about $5.5 billion in previously unclaimed super. But there’s still nearly $19 billion waiting to be found. A few minutes today could translate into a healthier retirement balance later. It’s easy to put super in the “deal with it later” basket, but it’s still your hard-earned money.
