Single-Member SMSF: Individual Trustee vs Corporate Trustee – Which Structure Is Better?

Setting up a single-member Self-Managed Super Fund (SMSF) gives you greater control over how your retirement savings are managed. However, before establishing your fund, one important decision is choosing the right trustee structure.

In Australia, a single-member SMSF can be established using either individual trustees or a corporate trustee. Both structures are permitted under superannuation law, but they have different requirements, costs and implications for the ongoing management of your fund.

So, which structure is more suitable for a single-member SMSF?

This guide explains the differences between individual and corporate trustees, including their advantages, disadvantages and important considerations when setting up your SMSF.

1. Can You Set Up a Single-Member SMSF with an Individual Trustee?

Yes. However, a single-member SMSF cannot have just one individual trustee.

Under the SMSF rules, a fund with individual trustees must have two trustees, even if there is only one fund member.

The member must be one of the two trustees, while the second trustee must meet certain relationship or employment requirements. The second trustee can be:

• A relative of the SMSF member; or
• Another individual, provided the SMSF member is not an employee of that person.

The second trustee does not need to be an SMSF member.

Both individual trustees are responsible for complying with the fund’s trust deed and superannuation legislation. They also have legal responsibilities in relation to the SMSF’s assets and administration.

2. Setting Up a Single-Member SMSF with a Corporate Trustee

A corporate trustee structure allows a single-member SMSF to operate with just one director.

Under this arrangement, a company is established to act as the trustee of the SMSF, and the sole SMSF member can also be the company’s sole director.

This structure allows the member to manage the SMSF without appointing another individual as a co-trustee.

A corporate trustee is a separate legal entity. The company holds the SMSF assets in its capacity as trustee, while the member acts as the company’s director and is responsible for ensuring the fund operates in accordance with superannuation and corporate laws.

For individuals who want to establish and manage their own SMSF independently, this can be a practical structure.

3. Individual Trustee vs Corporate Trustee: Key Differences

The following table highlights the main differences between the two structures.

4. Advantages and Disadvantages of Individual Trustees

Advantages

Lower establishment costs

An individual trustee structure generally costs less to establish because there is no need to register a separate trustee company.

No annual ASIC review fees

Individual trustees do not have to pay an annual company review fee to ASIC.

Fewer corporate compliance obligations

There is no separate trustee company requiring annual ASIC company reviews and associated corporate administration.

Disadvantages

You need another individual trustee

Even though the SMSF has only one member, you must appoint a second individual trustee who meets the legal requirements.

Shared legal responsibility

Both trustees have legal responsibilities for the SMSF. The second trustee is not simply a nominee or administrative contact.

Both trustees must be involved

The trustees must comply with the fund’s governing rules and properly authorise decisions. Depending on the transaction and fund documentation, both trustees may need to sign relevant documents.

Changes to asset ownership records

SMSF assets are generally registered in the names of the individual trustees as trustees for the fund. If a trustee changes, the ownership records may also need to be updated.

This can create additional administrative work and costs, particularly where the fund owns investment property.

Trustee replacement considerations

If the second trustee resigns, dies or becomes unable to act, the fund must address the trustee arrangements to maintain its SMSF status.

This may involve appointing another eligible trustee or changing to a corporate trustee structure.

5. Advantages and Disadvantages of a Corporate Trustee

Advantages

Greater independence and control

A single member can be the sole director of the corporate trustee, allowing them to manage the SMSF without relying on another individual as a co-trustee.

No need for a second individual trustee

This is one of the main reasons many single-member SMSF owners prefer a corporate trustee.

Continuity of asset ownership

The corporate trustee remains the legal trustee even if its directors change.

This means changes to directors generally do not require the SMSF to transfer assets into a new trustee’s name.

For SMSFs holding investment properties, shares and other assets, this can be an important administrative advantage.

Greater flexibility for future changes

If you later decide to add another member, the corporate trustee structure can accommodate changes in membership without necessarily changing the legal ownership of the fund’s assets.

The new member will generally need to become a director of the corporate trustee.

Clearer separation of legal responsibilities

A dedicated corporate trustee provides a separate legal entity through which the SMSF holds its assets and conducts its activities.

Disadvantages

Higher initial establishment costs

A corporate trustee requires the registration of a company with ASIC, resulting in additional establishment costs.

Annual ASIC review fees

The corporate trustee company must remain registered and comply with ASIC’s annual review requirements.

For the 2026–27 financial year, the ASIC annual review fee for a special purpose proprietary company is $70. A standard proprietary company has a higher annual review fee of $342.

Additional corporate compliance

The company must comply with its constitution and relevant corporate obligations, including maintaining accurate director and company records.

Directors must also obtain a Director Identification Number (Director ID).

6. Which Trustee Structure Is Better for a Single-Member SMSF?

There is no single answer for every SMSF owner. The appropriate structure depends on your circumstances, investment strategy, expected administration costs and future plans.

However, a corporate trustee is often a practical option for individuals establishing a single-member SMSF.

The reasons include:

• You can manage the SMSF as the sole director without appointing another individual trustee.
• The corporate trustee provides continuity when directors change.
• Changes in fund membership generally do not require changes to the legal ownership of SMSF assets.
• It can make ongoing administration more straightforward, particularly when the SMSF holds property or other significant investments.

Although a corporate trustee involves higher initial and ongoing costs, these costs should be considered against the administrative flexibility and continuity it provides.

An individual trustee structure may still be appropriate where minimising establishment costs is a priority and a suitable second trustee is available.

7. Can You Change from Individual Trustees to a Corporate Trustee?

Yes. An existing SMSF with individual trustees can generally change to a corporate trustee structure.

However, the process involves more than simply registering a company.

The fund must review its trust deed, establish and appoint the corporate trustee, update the relevant ATO and ASIC records, and arrange for SMSF assets to be transferred or re-registered where required.

For funds holding investment properties, the change may involve additional legal, registration and potential state duty considerations.

It is important to plan the transition carefully before making changes to the trustee structure.

Frequently Asked Questions (FAQs)

Can I set up an SMSF on my own?

Yes. You can establish a single-member SMSF with a corporate trustee and act as the company’s sole director. If you choose individual trustees, you must have two individual trustees.

Does a single-member SMSF need two trustees?

It depends on the structure. An SMSF with individual trustees requires two trustees. An SMSF with a corporate trustee can have one director, who is also the sole member.

Can the second trustee of a single-member SMSF be a non-family member?

Yes. The second individual trustee can be someone who is not related to the member, provided the member is not an employee of that trustee.

Is a corporate trustee compulsory for a single-member SMSF?

No. Both individual and corporate trustee structures are permitted, provided the fund meets the relevant SMSF requirements.

How much does it cost to maintain a corporate trustee?

The cost depends on the type of company. For 2026–27, the ASIC annual review fee for a special purpose proprietary company is $70. Other establishment and administration costs may also apply.

Can I add my spouse to my single-member SMSF later?

Yes. A single-member SMSF can generally accept additional members, subject to the fund’s trust deed and superannuation laws. Under a corporate trustee structure, each member must generally also be a director of the corporate trustee.

What happens if the sole director of an SMSF corporate trustee dies?

The fund needs appropriate succession arrangements. A legal personal representative may be able to act in place of the member in certain circumstances under the superannuation rules. The fund’s trust deed and company constitution should also be reviewed to ensure appropriate arrangements are in place.
