Unit Trusts for Property Developers
Advice on Property Developer’s Unit Trusts by Property Tax Specialists
Unit Trusts for Residential Property Development in Australia
For small to medium residential property developers in Australia, a unit trust is one of the most commonly considered structures for projects involving more than one investor or development participant.
Unit Trusts offers clear and documented ownership proportions, a practical framework for sharing development profits, and a structure that can accommodate co-investors who are unrelated to each other – something a family trust generally cannot do.
That said, a unit trust carries its own set of tax implications, compliance obligations, and structural constraints that are specific to development activity and are frequently not well understood at the point of project setup. The interaction between unit trust treatment, GST obligations, the margin scheme, and the fixed trust rules is an area where specialist advice before acquisition can make a material difference to the financial outcome of a project.
At Property Tax Specialists, we advise residential developers on whether a unit trust is the right vehicle for their project, how it should be established, and how it compares to other structures (including a family trust) for the specific circumstances of their development.

Unit Trust vs Family Trust for Property Development.
Which Is Right for Your Project?
The choice between a unit trust and a family trust for a development project is one of the most common structuring questions we are asked, and the answer depends primarily on who is involved in the project and what their relationship is to each other.
A family trust distributes income at the trustee’s discretion among a defined family group. It is well suited to a single developer or a family-based development operation where flexibility in profit distribution and the benefits of the family trust election are priorities. It is not appropriate where development profits need to be shared with unrelated co-investors, because distributions outside the defined family group attract family trust distribution tax at the top marginal rate plus the Medicare levy.
A unit trust divides ownership into fixed units, with each unitholder entitled to income and capital in proportion to their unitholding. Because entitlements are fixed and documented rather than discretionary, a unit trust can accommodate unrelated parties investing in the same project without the distribution constraints that apply to a family trust. This makes it the more natural vehicle for joint venture development projects, projects where external capital has been brought in, or any development arrangement involving two or more parties who are not part of the same family group.
The trade-off is that the fixed nature of a unit trust eliminates the income distribution flexibility that makes family trusts attractive. Each participant receives their share of the development profit in proportion to their units, regardless of their individual tax position. There is no ability to direct more profit to a lower-income participant to reduce the group’s overall tax burden.
Understanding which structure is appropriate for a given project requires looking at the full picture (who is involved, what their relationship is, what the financing arrangements are, and what the GST implications are) before any commitment is made.

How Development Income Is Treated in a Unit Trust
Development Profits Are Ordinary Income, Not Capital Gains
As with a family trust used for development, profits generated by residential development activity inside a unit trust are generally treated by the ATO as ordinary income rather than capital gains. Where the purpose of acquiring and developing property is to sell it at a profit, the activity is considered to constitute carrying on a business or undertaking a profit-making scheme rather than the passive realisation of a capital asset.
This means the 50% CGT discount that applies to assets held for more than 12 months is generally not available on development profits. Income flows through to unitholders as ordinary income, taxed at their applicable marginal rates in the year of receipt. For a development project with a substantial profit, the tax outcome at distribution can be significant, and understanding it before the project begins is part of sound structure planning.
Business Activity vs Passive Investment in a Unit Trust Context
Whether a development activity constitutes carrying on a business affects a range of tax outcomes, including how losses are treated, whether certain small business concessions apply, and (critically in a unit trust context) how the trust is classified for GST and margin scheme purposes. The ATO assesses the nature, scale, repetition, and commercial organisation of the activity in making that determination.
For developers using a unit trust, the classification of the trust’s activity has direct implications for the fixed vs non-fixed trust analysis, which in turn affects GST and margin scheme eligibility. This is explained in detail in the section below.

Fixed vs Non-Fixed Unit Trusts.
Why It Matters for GST and the Margin Scheme
This is the area where the technical distinction between a fixed and non-fixed unit trust has the most practical consequences for residential developers, and it is an area that is frequently overlooked during structure setup.
What Makes a Unit Trust Fixed or Non-Fixed?
Under Australian tax law, a unit trust is treated as a fixed trust if unitholders have fixed and indefeasible entitlements to both income and capital throughout the life of the trust.
This sounds straightforward, but in practice many unit trust deeds contain provisions that undermine fixed trust status – for example, clauses that give the trustee discretion over how income is allocated, provisions that allow units to be redeemed or reissued in ways that alter entitlements, or terms that create different classes of units with different rights.
If any of those provisions are present, the ATO may treat the trust as non-fixed, with significant consequences.

How Fixed Trust Status Affects GST and the Margin Scheme
The margin scheme is a GST concession available to developers that allows GST to be calculated on the margin between the purchase price and the sale price of a property, rather than on the full sale price. It can substantially reduce the GST liability on a development project and is often the difference between a project being financially viable and one that is not.
Eligibility for the margin scheme depends on how the property was acquired. Where a property is acquired by a trust, the trust’s classification as fixed or non-fixed affects whether the margin scheme is available on a subsequent sale, and on what basis.
In particular, where units in a unit trust are sold rather than the underlying property (a common exit strategy in joint venture development projects) the GST treatment of that transaction depends heavily on whether the trust is correctly structured as a fixed trust. A non-fixed trust can create unexpected GST outcomes that are difficult and costly to unwind, particularly once the project is already underway.
Getting the trust deed right from the outset (ensuring it genuinely creates fixed and indefeasible entitlements and does not inadvertently include provisions that compromise fixed trust status) is essential for developers who intend to rely on the margin scheme or who may exit the project through a unit sale rather than a direct property sale.
Input Tax Credits and GST Registration in a Development Trust
Where a unit trust is carrying on a development enterprise, it must be registered for GST if its turnover meets the registration threshold. Input tax credits (the ability to claim back GST paid on development costs including construction, professional fees, and other project expenses) are available to a GST-registered trust, provided the costs are incurred in the course of making taxable supplies.
The interaction between the trust’s GST registration, the margin scheme election, and the treatment of individual unitholders’ contributions and returns requires careful planning. Where unitholders are themselves GST-registered entities, the flow-through of GST obligations and credits between the trust and its unitholders adds a further layer of complexity that should be addressed as part of structure planning rather than managed reactively during the project.
These are areas where the consequences of getting it wrong (whether through an inadequate trust deed, an incorrect margin scheme election, or a failure to register for GST at the right time) can be material and sometimes irreversible. We flag them here because they are consistently underweighted in early-stage development planning.

The Benefits of Using a Unit Trust for Residential Property Development
1. Clear and Documented Ownership for
Co-Investors
Because interests are fixed and documented in the trust deed, a unit trust provides genuine clarity for development participants. Each unitholder knows exactly what percentage of the project they own, what profit they are entitled to at completion, and what their position is if the arrangement needs to change during the project. This reduces the potential for disputes and provides a clear framework for resolving disagreements about project decisions.
For development projects involving two or more unrelated parties (business partners, investors bringing capital, or participants contributing land or expertise) this clarity is one of the most practically important features of the unit trust structure.
2. Suitable for Joint Ventures and External Capital
Unlike a family trust, a unit trust can accommodate unrelated co-investors without triggering punitive distribution tax. Units can be issued to bring in additional investors without restructuring the entire arrangement, making a unit trust a practical vehicle for projects where capital requirements change across different stages or where the developer wants to bring in a passive investor for a specific project while retaining development control.

3. Profit Sharing at Project Completion
When development profits are realised at settlement, they flow to unitholders in proportion to their unitholdings. This provides a straightforward and commercially transparent basis for sharing returns that is easily understood by all participants and readily documented for financing and accounting purposes.
4. Asset Separation and Protection Potential
Assets held within a properly structured unit trust are separate from the personal assets of individual unitholders, providing a degree of protection against creditor claims during the development project.
The extent of that protection depends on how the structure is established (including whether a corporate trustee is in place) and requires active management to remain effective throughout the project lifecycle.

The Risks and Limitations of Unit Trusts for Property Development
No Flexibility in Profit Distribution
The fixed nature of a unit trust means that development profits are distributed strictly in proportion to unitholdings, regardless of each participant’s individual tax position.
If one unitholder is on a significantly higher marginal tax rate than another, there is no ability to adjust the distribution to reduce the group’s overall tax burden.
For a family-based development operation where income flexibility is a priority, a family trust may be a more appropriate structure.
Development Losses Flow to Unitholders in Fixed Proportions
During the development phase, where the trust incurs costs before income is received, any losses or deductions flow to unitholders in proportion to their unitholdings. Unitholders cannot choose to absorb more or less of the loss than their unitholding dictates.
Where unitholders have different capacities to utilise those losses against their other income, this fixed allocation may produce a less tax-efficient outcome than a structure with more flexibility.

Stamp Duty on Unit Transfers
Transferring units in a unit trust that holds land-rich assets (which will typically be the case during a development project) can trigger stamp duty in most Australian states.
This can make it difficult and expensive to change the ownership composition of a project once it is underway, whether because a participant wants to exit, a new investor wants to join, or the project needs to be restructured.
The stamp duty implications of any anticipated unit transfers should be assessed before the project begins, not at the point a transfer is contemplated.
Financing Complexity
Lenders assess unit trust structures differently to individual borrowers or companies, and some lenders are more restrictive in how they approach trust lending.
For development projects requiring construction finance and progressive drawdowns, the financing arrangements need to be confirmed as compatible with the trust structure before acquisition. A structure that cannot be financed on acceptable terms is not a viable structure, regardless of its other advantages.

Land Tax on Development Land
Development land held within a unit trust does not qualify for land tax thresholds in most Australian states. In New South Wales and Victoria in particular, land tax is payable from the first dollar of taxable land value.
For projects involving a lengthy planning or construction phase that spans one or more land tax assessment dates, this is a recurring cost that needs to be built into project feasibility modelling from the outset.
Trust Deed Quality and Ongoing Compliance
As noted above in the context of fixed trust status and GST, the quality of the unit trust deed is not a minor consideration for developers.
A deed that inadvertently compromises fixed trust status can affect margin scheme eligibility and GST treatment in ways that are difficult to remedy once the project is underway.
Beyond the initial setup, ongoing compliance (trustee resolutions, tax returns, GST reporting, and unitholder documentation) requires active attention throughout the project lifecycle.

Structure Planning and Structure Reviews for Development Unit Trusts
by Property Tax Specialists
Whether you are planning your first joint venture development project or you have been developing through a unit trust for years without an independent review, the structural decisions involved have long-term consequences for how profits are taxed, how GST is managed, and how protected your position is throughout the project.
Trust Structure Planning Service
Our structure planning service works with you before acquisition to assess whether a unit trust is the right vehicle for your development project, how the deed should be drafted to ensure fixed trust status and margin scheme eligibility, how GST registration and input tax credit entitlements should be managed, and how the structure integrates with your financing arrangements and broader tax position.
Trust Structure Review Service
Our structure review service examines existing arrangements to identify whether the current structure continues to serve your interests, whether the trust deed genuinely creates fixed and indefeasible entitlements, whether GST obligations are being managed correctly, and what options exist where a restructure or deed update is warranted.
Both services are built on the same principle that shapes everything we do: the right structure is not determined by a single factor but by the full picture of who is investing, what they are seeking to achieve, and what their tax position looks like today and in the future.
