An SMSF trustee can either be a group of individuals or a company. Those two choices are usually called individual trustees and a corporate trustee.
It is the most basic structural decision in an SMSF, and one many trustees never revisit. You chose a trustee structure when the fund was set up, and for most funds the choice has sat quietly in the background ever since.
That choice is worth a second look.
Your trustee structure affects how fund assets are titled, what happens when a member joins or dies, whether a single-member fund needs a second person involved, what ASIC costs apply, and how large an ATO administrative penalty can become if something goes wrong.
The sector has also moved heavily in one direction, with corporate trustees now the clear majority structure.
This article explains how the two structures work, where the costs sit, how penalties can multiply differently, and what usually needs to happen if the fund changes structure later.
For the broader setup sequence, see the SMSF Setup Guide. For trustee duties after setup, see the SMSF Trustee Obligations Guide.
Key Takeaways
- Every SMSF has either individual trustees or a corporate trustee. It cannot use both at the same time.
- Individual trustees are cheaper at setup because there is no company to register, but asset titles generally need to be changed whenever the trustee line-up changes.
- A corporate trustee costs more upfront and pays an annual ASIC review fee, but the company remains the legal holder of fund assets when members or directors change.
- ATO administrative penalties are applied to each individual trustee separately, but generally only once to a corporate trustee.
- Administrative penalties must be paid personally. They cannot be paid or reimbursed from SMSF assets.
- Changing from individual trustees to a corporate trustee is possible, but it should be planned carefully because it involves deed, ATO, ASIC and asset-title steps.
Individual trustee vs corporate trustee: the core difference
An SMSF can be run in one of two ways.
With an individual trustee structure, each member of the fund is personally appointed as a trustee. The members and trustees are the same people wearing two hats. Fund assets are held in the names of those individuals, usually with wording that makes clear they hold the assets as trustees for the SMSF.
With a corporate trustee structure, a company is set up to act as trustee. Each member is usually a director of that company. The fund’s assets are held in the company’s name as trustee for the fund.
The company should be a special purpose company whose sole purpose is to act as trustee of the SMSF. It should not run a trading business or hold its own investment assets. ASIC explains the special purpose company rules on its special purpose companies page.
| Feature | Individual trustees | Corporate trustee |
|---|---|---|
| Who acts as trustee? | The members personally | A company |
| Who controls the trustee? | The individual trustees | The company directors |
| Asset titles | Names of the individual trustees | Company name |
| Single-member fund | Needs a second individual trustee | Can have a sole director |
| ASIC annual review fee | None | Applies to the trustee company |
| Member changes | Asset titles commonly need updating | Company remains the legal holder |
| Administrative penalties | Applied to each individual trustee separately | Generally applied once to the company |
In both structures, the same people usually fill both roles. As a member, you are a beneficiary of the fund. As a trustee or director of the corporate trustee, you are responsible for running the fund within superannuation law.
The ATO’s trustee structure guidance sets out the official comparison.
SMSF trustee and director rules
An SMSF can have no more than 6 members. That limit flows through to the trustee structure.
For most funds with more than one member:
- each member must be an individual trustee, or a director of the corporate trustee
- each individual trustee or director must generally be a member
- no member can be a disqualified person
- no trustee or director can be paid from the fund for trustee duties.
Single-member funds have special rules. An SMSF with individual trustees needs 2 individual trustees even where there is only 1 member. The second trustee does not have to be a member, although relationship and employer rules can matter.
A single-member SMSF with a corporate trustee can have the member as the sole director. That is one of the cleanest practical differences between the structures.
| Rule | Individual trustees | Corporate trustee |
|---|---|---|
| Minimum trustees or directors | 2 individual trustees | 1 director |
| Maximum members | 6 | 6 |
| Single-member fund | Needs a second individual trustee | Sole director permitted |
| Must every member be involved in control? | Yes, as trustee, subject to limited exceptions | Yes, as director, subject to limited exceptions |
For a fund still at setup stage, this decision sits alongside the trust deed, trustee declarations, bank account, investment strategy and registration process. The SMSF Setup Guide walks through those steps in order.
Corporate trustee costs and ASIC fees
Cost is the main reason some people choose individual trustees at setup.
An individual trustee structure avoids the need to register a company, so the upfront establishment cost is lower. There is also no ASIC annual review fee because no company exists.
A corporate trustee costs more upfront because the company must be registered with ASIC. ASIC company registration fees are indexed each 1 July. From 1 July 2026, the company registration fee is $636. A standard proprietary company annual review fee is $342, but an eligible special purpose SMSF trustee company pays the lower annual review fee of $70.
The special purpose company status matters. A company that is meant to act only as trustee of an SMSF should be registered and maintained correctly so it remains eligible for the reduced fee.
| Cost item | Individual trustees | Corporate trustee |
|---|---|---|
| Company registration | Not required | $636 from 1 July 2026 |
| ASIC annual review fee | Not applicable | $70 for an eligible special purpose company |
| Standard proprietary annual review comparison | Not applicable | $342 if not treated as special purpose |
| Setup simplicity | Lower upfront paperwork | More setup steps |
| Long-term administration | More re-titling risk when people change | More stable asset ownership |
For a full view of establishment and ongoing expenses, see the SMSF Costs and Fees Guide.
The cost trade-off is not just “cheap now” versus “expensive now”. Individual trustees may save money at setup but can create larger administration costs later if assets must be re-titled after death, divorce, incapacity or a membership change.
ATO administrative penalties by trustee structure
This is the difference trustees often learn about too late.
When the ATO issues an administrative penalty for certain breaches of superannuation law, the penalty is calculated using penalty units. One penalty unit is $364 from 1 July 2026 under the Crimes (Amount of a Penalty Unit) Instrument 2026.
Some serious SMSF contraventions carry a 60 penalty unit amount. At $364 per unit, that is $21,840.
For a corporate trustee, the penalty is generally imposed once on the company. For individual trustees, the same penalty is imposed separately on each individual trustee.
| Scenario | Penalty units | Penalty per trustee or company | Number of penalties | Total |
|---|---|---|---|---|
| Corporate trustee | 60 | $21,840 | 1 | $21,840 |
| 2 individual trustees | 60 | $21,840 | 2 | $43,680 |
| 3 individual trustees | 60 | $21,840 | 3 | $65,520 |
| 4 individual trustees | 60 | $21,840 | 4 | $87,360 |
Same breach. Same fund. Different trustee structure.
The ATO’s SMSF non-compliance guidance also makes the personal payment point clear: administrative penalties must not be paid or reimbursed from the SMSF.
The ATO can remit penalties depending on the circumstances, but trustees should not assume remission will be granted. The better assumption is simple: structure affects the penalty exposure before a breach happens. Changing to a corporate trustee after the fact does not undo a penalty already triggered under an individual trustee structure.
For broader compliance context, see the SMSF Rules and Limits Reference and the SMSF Audit Guide.
Asset titles when members change
The other major difference is asset ownership.
With individual trustees, fund assets are held in the names of the individuals as trustees. When a trustee changes, the legal owner on every asset title may need to change too.
That can mean:
- property title office paperwork
- bank account updates
- broker and share registry changes
- managed fund transfer forms
- term deposit and platform account updates
- professional fees and lodgement costs.
The key point is that re-titling is not the same as selling the asset. The SMSF remains the beneficial owner. But the legal title still needs to reflect the current trustee correctly.
With a corporate trustee, the company remains the trustee. When a member joins, leaves or dies, the company directors and fund records may change, but the company holding the asset does not. That usually avoids the need to re-title every fund asset.
| Event | Individual trustees | Corporate trustee |
|---|---|---|
| New member joins | Add trustee and update asset titles | Add director and update records |
| Member leaves | Remove trustee and update asset titles | Remove director and update records |
| Member dies | Appoint replacement trustee if required and update titles | Company continues, subject to director and deed requirements |
| Divorce or restructure | Multiple legal titles may need updates | Company can remain asset holder |
| Single-member fund | Needs a second trustee | Sole director structure can continue |
For official guidance on how fund assets should be titled, see the ATO’s ownership of SMSF investments page.
Death, incapacity and succession
The death of a member can expose the practical difference quickly.
In a two-member fund with individual trustees, the death of one trustee can leave the fund with only one individual trustee. The fund then needs to restore a valid structure, deal with trustee appointment documents, and update asset titles at a difficult time.
A corporate trustee can give the fund more continuity because the company continues after a member dies. The remaining director or replacement directors may still need to act under the trust deed, company constitution and superannuation law, but the legal owner of the fund assets is usually unchanged.
That does not mean trustee structure solves estate planning. It does not.
Binding death benefit nominations, reversionary pensions, legal personal representative appointments and control of the trustee all still need to be checked against the fund deed and the member’s circumstances. But a corporate trustee can reduce the immediate administration pressure because the fund is not forced into the same asset-title scramble.
For the estate planning layer, see the SMSF Death Benefits and Estate Planning Guide and Binding Death Benefit Nominations for SMSFs.
How to change from individual trustees to a corporate trustee
Your trustee structure is not locked in forever. Many funds start with individual trustees and later change to a corporate trustee.
The change should be handled carefully. It does not usually require selling SMSF assets or rolling members to a new fund, but it does involve legal and administrative steps.
General steps usually include:
- Review the trust deed. Check whether the deed supports the trustee change and whether a deed variation is required.
- Register the company. Set up a special purpose company with ASIC. Each proposed director needs a director identification number before appointment.
- Appoint the company as trustee. Prepare trustee appointment and resignation documents in line with the deed and superannuation law.
- Sign trustee declarations. Each new director must sign the ATO trustee declaration within 21 days of appointment.
- Notify the ATO within 28 days. The ATO says changes to trustees, directors, members and fund status must be reported within 28 days. You cannot use the annual return to tell the ATO about a trustee structure change.
- Update ASIC and fund records. Keep company officeholder details, minutes, trustee consents and fund records current.
- Re-title fund assets. Move legal title from the individual trustees to the corporate trustee where required.
When trustee changes are notified, the ATO may review the fund. Its change notification guidance says a fund’s Super Fund Lookup status may show “Regulation details withheld” while further review is conducted, and that the ATO aims to complete these reviews within 56 days.
That can affect rollovers, employer contributions, bank onboarding or other transactions that rely on the fund’s public status. Timing matters. A trustee structure change is usually best done away from urgent rollovers, property settlements or contribution deadlines.
Which SMSF trustee structure is more common?
Corporate trustees are now the clear majority structure in the SMSF sector. The ATO’s latest annual statistics show roughly 72% of SMSFs use a corporate trustee, and corporate trustee use is even more common among newly established funds.
That does not mean every individual trustee fund is wrong. An individual trustee structure can be simpler and cheaper at setup, particularly for a straightforward two-member fund with low change expectations.
But the case for a corporate trustee tends to compound over time:
- one penalty rather than one penalty per individual trustee
- simpler single-member fund structure
- cleaner asset ownership when members change
- fewer re-titling events
- better continuity after death or incapacity
- easier separation between fund assets and personal names.
If your fund still has individual trustees, this is not a reason to panic or rush. It is a reason to understand the structure you have and raise the question with your accountant, SMSF administrator or adviser when the fund is next reviewed - especially if membership may change, a member is approaching retirement, or estate planning is being updated.
What to do next
Before changing trustee structure or setting up a new SMSF, work through the practical checks rather than treating the decision as a simple fee comparison.
- If you are setting up a new fund: start with the SMSF Setup Guide and confirm trustee structure before the deed and bank account are arranged.
- If your fund already has individual trustees: ask your accountant or SMSF administrator what assets would need to be re-titled and what the professional, registry and state duty steps would involve.
- If estate planning is the trigger: review trustee control alongside your deed, binding death benefit nominations and pensions. The SMSF Death Benefits and Estate Planning Guide covers those issues separately.
- If compliance risk is the concern: use the SMSF Trustee Obligations Guide and Rules and Limits Reference to identify the obligations most likely to create personal penalties.
- If timing matters: avoid making the change during urgent rollovers, property settlements, contribution deadlines or bank onboarding.

Frequently Asked Questions
Can an SMSF have both individual trustees and a corporate trustee?
No. An SMSF uses one trustee structure at a time. It is either run by individual trustees or by a company acting as corporate trustee.
Is a corporate trustee required for an SMSF?
No. A corporate trustee is not compulsory for every SMSF, but it is often preferred because it can simplify single-member funds, member changes, asset titles, succession and administrative penalty exposure.
How many members can an SMSF have?
An SMSF can have no more than 6 members. The member and trustee or director rules must continue to be met, including the special rules for single-member funds.
Why can ATO penalties be higher with individual trustees?
Because the penalty notice is generally issued to each individual trustee separately. A two-trustee fund can therefore face two penalties for the same breach, while a corporate trustee structure generally receives one penalty notice for the company.
Can SMSF administrative penalties be paid from the fund?
No. The trustee or corporate trustee directors need to meet the penalty personally. Using SMSF money to pay or reimburse the penalty creates a separate compliance problem.
Does changing to a corporate trustee remove an earlier penalty?
No. The structure in place when the breach occurred is what matters. Changing trustee structure later does not undo a penalty already triggered under an individual trustee structure.
Do SMSF assets need to be sold when changing to a corporate trustee?
Usually no. A trustee change is generally a change in legal ownership rather than beneficial ownership, but asset titles and registry records may still need to be updated. State duty and transfer requirements should be confirmed before the change.
Does trustee structure affect binding death benefit nominations?
The validity and operation of binding death benefit nominations mainly depends on the fund’s trust deed and superannuation law. A corporate trustee may help continuity because the company continues after a member dies, but the nomination still needs to be valid under the deed.
