Many Australian small businesses and investment groups hold their assets through a trust, and in most of those structures the trustee is a company rather than a person. The idea is simple: the company acts as the legal owner and manager of the trust's assets, while the people behind it stay one step removed from the trust's liabilities. What is less simple is how the structure actually operates, who holds real control, and where the promised protection runs out.
This article walks through the mechanics of a corporate trustee: the parties involved and what each one does, why a company is used instead of an individual, how control flows through directors, shareholders and the appointor, how the structure is set up and run, and the points where directors and family members can still end up personally exposed. It is written for founders, directors and family business operators deciding whether a corporate trustee is right for them, or trying to understand the one they already have.
The players: who does what in a corporate trustee structure
The most important structural fact is that a trust is not a separate legal entity. It has an ABN and a tax file number, but it cannot own property, sign contracts or be sued in its own name. Everything the trust does is done by its trustee. When the trustee is a company, the structure looks like this:
- Trustee company: holds legal title to the trust's assets, signs contracts, collects income and makes distributions under the trust deed. It is a company in its own right, with its own ACN.
- Directors: run the trustee company. They make the decisions that the trust acts on and owe duties under the Corporations Act 2001 (Cth).
- Shareholders: own the trustee company and appoint its directors. In a family structure these are usually the founders or family members.
- Appointor: the person or entity named in the trust deed who can remove and appoint the trustee. In many family trusts the appointor is the real control point, even though they may hold no shares.
- Beneficiaries: the people or entities entitled to receive income or capital from the trust according to the deed.
- Outside the structure: ASIC regulates the company, the ATO deals with the trust's tax affairs, and banks, suppliers and customers contract with the trustee company as the legal face of the trust.
Keeping these roles straight matters. A common misunderstanding is that owning the trustee company means owning the trust's assets. It does not. The trust's assets belong to the trust, and the person who controls them is the trustee acting under the deed, subject to the appointor's power to replace the trustee.
Why a company rather than a person
A trust can be run by an individual trustee, and many start that way because it is cheap and quick. The reason so many structures move to a company is what happens when something goes wrong or when people change.
An individual trustee is personally liable for the trust's debts. They have a right to be reimbursed out of trust assets for liabilities properly incurred, but if the trust's assets fall short, the trustee's own assets are on the line. If that trustee dies, loses capacity or becomes bankrupt, the trust's affairs are disrupted, and the trust's assets generally have to be transferred to a replacement trustee, which is a costly and slow process involving title searches, bank updates and possibly duty.
A company changes both of those outcomes. Because the company is a separate legal entity, the trust's liabilities sit with the company, not with the individuals behind it. Directors are not, in the ordinary course, personally liable for the company's debts. And because a company has perpetual succession, changing directors or shareholders does not disturb legal title to the trust's assets. Control can be reshuffled at the company level without re-papering every asset.
The trade-offs are real. A corporate trustee costs more to establish and maintain: there are ASIC registration and annual review fees, annual lodgments and a second set of governance obligations on top of the trust's own administration. The protection is also not absolute, as the section on liability traps below sets out. For many businesses the cost is worth it, but it should be a deliberate choice rather than a default.
Where control actually sits
Control of a corporate trustee structure is split across three documents and three groups of people, and the split is often not where owners expect it to be.
The directors run the company from day to day and make the decisions the trust acts on. The shareholders appoint and remove directors and approve major company-level changes. But neither group controls the trust itself. The trust is controlled through the trust deed, and the deed typically gives the appointor the power to remove and appoint the trustee. That means an appointor who holds no shares and sits on no board can, in effect, replace the trustee company with a different one if they are unhappy with how the trust is being run.
This matters in practice. When a business partner or family member wants "control" of the trust, the question is not only who owns the shares. It is who is appointor, who can change the deed, and what the deed says about distributions. Disputes in family trusts frequently come down to a mismatch between what people believed they controlled and what the deed actually gives them. A well-drafted deed and constitution that line up with the commercial reality of who should make which decisions avoid that gap.
Setting the structure up
Establishing a corporate trustee is a two-part exercise: incorporate the company, then create the trust and appoint the company as its trustee.
The company is a proprietary limited company registered with ASIC. The Corporations Act 2001 (Cth) requires a proprietary company to have at least one director who ordinarily resides in Australia (s 201A). The company's internal management can be governed by the replaceable rules in the Act, by a company constitution, or by a combination of both (s 134). Many founders adopt a constitution tailored to how the business actually runs, particularly if more than one person will own or control the trustee company. A common choice is a special purpose company that only ever acts as trustee and does not trade in its own right, which keeps the company's own liabilities and the trust's liabilities cleanly separate.
The trust itself is created by executing a trust deed. The deed names the company as trustee and sets out the beneficiaries, the trustee's powers, how income and capital can be distributed, who the appointor is, and how the trustee can be replaced. Because the deed is the trust's founding document, getting its terms right at the start is far cheaper than fixing them later.
Once the trust exists, it needs its own registrations. The ABN and TFN are obtained for the trust in the trustee's name as trustee. A trust carrying on an enterprise must register for GST once its GST turnover reaches or exceeds $75,000, or $150,000 for a non-profit body (the threshold is set by s 23-15 of the A New Tax System (Goods and Services Tax) Act 1999 (Cth) and reg 23-15.01 of the GST Regulations 2019). A bank account should be opened in the trust's name and operated by the trustee company, and trust money kept strictly separate from the company's own money and anyone's personal money.
Running it day to day
Once the structure is operating, the work is keeping the two layers of obligations current.
The trustee must act within the deed, exercise care and diligence, and act in the best interests of the beneficiaries. Distributions must be made in accordance with the deed's terms and timeframes, and the decisions behind them recorded. This is not paperwork for its own sake: if no beneficiary is presently entitled to the trust's income, the trustee can be assessed on it, at penalty rates in some cases (s 99A of the Income Tax Assessment Act 1936 (Cth)). Properly documented distributions are what stop the trustee company from wearing a tax bill the family never expected.
The company layer has its own obligations. ASIC records must be kept current, the annual review fee paid, and financial records maintained. Directors owe the standard duties under the Corporations Act 2001 (Cth): care and diligence, good faith, and avoiding conflicts of interest and improper use of position. Minutes of director decisions, including decisions about the trust, are the evidence that those duties were discharged.
Capacity discipline is the quiet third obligation. Every contract, invoice and bank instruction should be in the company's name as trustee for the named trust, for example "XYZ Pty Ltd ATF XYZ Family Trust". The letters "ATF" stand for "as trustee for". A company that signs contracts in its own name without that capacity may take on liabilities in its own right, which is exactly what a special purpose trustee company was meant to avoid.
Where the protection ends
The corporate trustee structure reduces personal exposure; it does not eliminate it. There are several well-defined points where the individuals behind the company can still be pursued.
Directors can be asked to give personal guarantees, particularly by banks, landlords and major suppliers, and a guarantee binds the individual no matter how carefully the trust is structured. Directors can also be personally liable for debts the company incurs while insolvent: s 588G of the Corporations Act 2001 (Cth) requires a director to prevent the company from incurring debts while it is insolvent or while there are reasonable grounds to suspect it is, and a breach can make the director personally liable for the debts.
The ATO has a powerful collection tool of its own. Under Division 269 of Schedule 1 of the Taxation Administration Act 1953 (Cth), directors must cause the company to meet certain obligations, chiefly PAYG withholding and superannuation guarantee amounts, and unpaid amounts can be recovered from directors personally through director penalty notices. The ATO can pursue these even when the company itself is insolvent, and the defences are narrow.
Workplace law adds another layer. Under s 550 of the Fair Work Act 2009 (Cth), a person who is involved in a contravention of a civil remedy provision is taken to have contravened it themselves. A director who knowingly participates in underpaying employees, or who turns a blind eye to it, can face personal liability and penalties alongside the company.
Two structural points round out the picture. First, the trustee's right of reimbursement only runs against the trust's assets. If the trust's assets are insufficient, the trustee company bears the shortfall. Second, the protection depends on the company never acting in its own right. A trustee company that trades on its own account, holds its own debts or signs contracts without the "as trustee for" capacity starts to look like an ordinary trading company with its own creditors, and the clean separation that made the structure attractive begins to dissolve.
Changing trustee or changing control
The structure also needs to handle change, and this is where the corporate form earns its keep.
Moving from an individual trustee to a corporate trustee, or replacing one corporate trustee with another, follows the procedure in the trust deed, usually involving appointor consent and a deed of retirement and appointment. The banks, suppliers and the ATO need to be told, and legal title to each asset must move to the new trustee. A change of trustee does not, of itself, usually trigger a capital gains tax event, because the trust continues to hold its assets (the ATO's practice statement on change of trustee, PS LA 2012/2, deals with the position). But a change so fundamental that it amounts to a resettlement of the trust can have quite different tax and duty consequences, and state duties can apply to transfers of some assets, so this is a point for specialist advice before acting.
Changes of control within a corporate trustee structure are easier. Bringing in a new partner or buying someone out usually means adjusting the shareholding and directorships of the trustee company, and updating the appointor if the deed allows, without touching title to the trust's assets. The quality of the shareholders agreement and the deed determines how smoothly that goes. Valuation mechanisms, transfer restrictions and agreed processes for appointor changes turn what could be a family or partnership dispute into a mechanical step.
When to bring in a lawyer
A corporate trustee structure is assembled from documents that interact: the trust deed, the company constitution and, where there are co-owners, a shareholders agreement. Each needs to be drafted to fit the others and to fit the commercial reality of who should control what.
A lawyer's main role is at the points where getting it wrong is expensive: drafting and reviewing the deed and constitution so that control, distribution powers and trustee replacement match the owners' intentions; restructuring, adding partners or changing trustees where tax and duty consequences need to be assessed; and responding when a director penalty notice, an insolvent trading claim or a dispute arrives. In practice the lawyer works alongside the accountant, with the lawyer handling the deed mechanics and the accountant the tax outcomes, and the two need to see the same documents.
The question to answer before you sign
The corporate trustee's promise is that the trust's problems stop at the company's door. That promise holds only while two things are true: the company never acts outside its trustee capacity, and the people running the structure know exactly where control sits and where the liabilities can still land. Before setting one up, or before relying on one that already exists, be able to answer two questions from the documents, not from memory: who can remove the trustee, and does every contract name the company as trustee for the trust? Getting those answers right at the start, with a properly drawn deed and constitution, is what separates a structure that protects the family's assets from one that simply adds a second set of compliance costs.
