Most self-managed super funds (SMSFs) have more than one member, and those members are rarely at the same point in life. A couple might be a decade apart in age; parents and adult children sometimes share a fund. When members will retire — and start drawing on the fund — at different times, a single one-size Investment approach can quietly work against someone. Building an investment strategy that accommodates different retirement dates is one of the more sophisticated, and more important, tasks a multi-member SMSF faces ATO SMSF investment requirements.

The law already points you here

An SMSF's investment strategy must have regard to the circumstances of the fund, and the ATO makes clear that this includes the personal circumstances of all members — their ages, their retirement horizons, and their needs ATO SMSF investment requirements. In a fund where one member is 55 and accumulating while another is 68 and drawing a pension, “the circumstances of the fund” are genuinely mixed. A strategy that treats the members as identical does not meet that requirement well.

The core tension: growth versus stability

The heart of the challenge is that different retirement dates call for different investment characteristics. A member many years from retirement can usually tolerate more growth-oriented, volatile assets, because they have time to ride out market cycles. A member already drawing a pension typically needs more stability and, crucially, Liquidity — cash and income to fund pension payments without being forced to sell growth Assets at a bad time. Blend everyone into one portfolio and you risk either starving the younger member of growth or exposing the retiree to Volatility and a cash-flow squeeze.

Two ways to structure the fund

Broadly, there are two approaches. The first is a single whole-of-fund strategy that deliberately balances the competing needs — for example, holding enough liquid, defensive assets to cover the retiree's pension for a year or two, while the remainder pursues growth for the younger member. The second is to maintain member-specific investment approaches within the fund, sometimes supported by segregating assets to particular members. Segregation can align each member's balance with investments suited to their horizon, though it adds administrative complexity and interacts with how the fund claims its Earnings tax exemption ATO income stream rules.

Liquidity is the pressure point

Whatever structure you choose, liquidity is where different retirement dates bite hardest. The member drawing a pension needs cash each year, and the minimum drawdown rises with age ATO income stream rules. If the fund's growth assets belong, in substance, to the younger member, the trustees must ensure the retiree's pension can be funded without selling those assets prematurely. Mapping expected pension payments, contributions and income against the fund's liquid holdings — and revisiting that map as retirement dates approach — is the practical core of the strategy.

A hypothetical example

Hypothetical: Anna is 56 and still working; her husband Peter is 68 and drawing a $60,000 pension from their $1.6 million SMSF. If the whole fund were invested for Anna's long horizon — heavily in growth shares — Peter's pension might have to be funded by selling shares in a downturn, locking in losses. Instead, the trustees hold about $130,000 in cash and income assets to cover roughly two years of Peter's pension and fund expenses, while the balance pursues growth suited to Anna's timeframe. Their written strategy records both members' circumstances and how the fund will meet Peter's cash needs. As Anna nears retirement, they plan to review and rebalance.

The role of contributions and pensions together

A multi-generational or age-gapped fund has a lever that a single-member fund lacks: while one member is still contributing, those inflows can help meet the other member's pension payments, keeping the fund's investments intact rather than forcing sales. With the concessional cap at $32,500 and the non-concessional cap at $130,000 for 2026-27, a working member can add meaningfully to the fund each year ATO contribution caps. Coordinating one member's contributions with another's drawdowns turns the age gap into a source of stability. But this only works if the strategy anticipates it — treating contributions and pension payments as a single cash-flow system rather than unrelated events.

Watch how segregation interacts with tax

If you decide to run member-specific investment pools, be aware that formally segregating assets to members interacts with how the fund claims its earnings tax exemption, and it is not always available — for instance where a member has a large total super balance and is in retirement phase, the fund may be required to use the proportionate method with an actuarial certificate instead ATO exempt current pension income. Segregation can be a clean way to match investments to horizons, but it carries administrative and tax consequences that should be understood before you commit to it. For many funds, a single balanced strategy with a deliberate liquidity buffer is simpler and achieves much the same result.

Review as the dates get closer

A strategy built around retirement dates is inherently time-sensitive. What suits a fund when the younger member is 55 will not suit it when that member is 63 and the older member is 75 and drawing a larger pension. Trustees should review the strategy regularly and whenever a member's situation changes — retiring, starting or stopping a pension, or making a large contribution ATO SMSF investment requirements. Documenting each review demonstrates that the trustees are managing the fund for all members, not just the loudest voice at the kitchen table.

For families sharing a fund, staggered retirement dates can actually be an advantage: contributions from the still-working member can help fund the retiree's pension, keeping assets invested. But that only works if it is planned. Sit down with the fund's numbers, set out each member's objectives and timeframe in writing, decide whether a balanced whole-of-fund approach or member-specific pools suits you, and keep enough liquidity for whoever is drawing on the fund. Different retirement dates are not a problem to be endured; handled deliberately, they are a structure to be used. The funds that manage this best are the ones that write down each member's timeframe and needs, agree how the fund will fund the earliest drawdowns, and revisit the plan every year rather than only when a crisis forces the conversation.
