One of the basic rules of an SMSF is how many members it can have — and it's often simpler than people expect.
An SMSF can have up to six members. This limit was increased from four in recent years, giving more flexibility for families or small groups who want to manage their super together.
What 'members' actually means
In an SMSF, members are the people whose super is held in the fund.
In most cases, members are also trustees (or directors of the corporate trustee). That means everyone in the fund is involved in how it's run — from investment decisions to compliance.
This structure differs from retail funds, where members don't assume any management role.
Common SMSF setups
While you can have up to six members, most SMSFs are smaller in practice.
You'll often see:
- Single-member funds
- Couples managing their super together
- Small family groups
Larger funds with four or more members are less common, mainly because decision-making becomes more complex as more people are involved.
Adding more members: what to consider
Just because you can have up to six members doesn't mean it always makes sense.
Before adding someone to an SMSF, it's worth thinking through how decisions will be made. Every member has a role in the fund, so differences in risk appetite, timelines or financial goals can create friction.
There are also practical considerations — contributions, benefit payments and record-keeping all become more involved as the number of members grows.
What happens if things change?
SMSFs are long-term structures, but member circumstances can change.
If someone wants to leave the fund, or if relationships shift, it can affect how the SMSF operates. In some cases, such changes may require restructuring or even winding up the fund.
Planning for this early — especially in multi-member funds — can save complications later on.
Final thoughts
While an SMSF can have up to six members, most funds are kept smaller for a reason.
The right number depends less on the limit itself and more on how well the members can work together over time.
