A couple in Parramatta are reviewing two draft deeds before committing to an investment property. One deed creates a unit trust, the other a discretionary family trust, and both could hold the same assets. The core decision is straightforward: a unit trust ties income and capital to ownership percentages, while a family trust gives the trustee discretion over who receives income, but only becomes a family trust for tax purposes after the trustee makes a family trust election.

A Parramatta Family Decides Between Two Trusts
The Parramatta couple has a practical question, not an academic one. Should their investment property and share portfolio be divided according to fixed ownership interests, or should the trustee retain flexibility to distribute income among eligible family beneficiaries each year?
A unit trust generally suits the first objective. Each unitholder has an interest linked to the units held, so the economic arrangement resembles a contract-like ownership split. A family trust generally suits the second. The trustee can decide which beneficiaries receive distributions and in what proportions, subject to the trust deed, tax law and any family trust election.
The distinction matters because trust structures are used extensively by Australian businesses and investors. Australian Taxation Office (ATO) trust statistics record 907,914 total trust tax returns in 2018–19 and 947,264 in 2020–21, while total business income reported by trusts rose from $390.65 billion to $428.99 billion across that period. These figures come from the ATO trust statistics.
That scale explains why the choice deserves more than a template deed. By 2020–21, the ATO totals represented roughly $453,000 of business income per trust on average, calculated from the reported totals. For a medical practice, property venture or family investment portfolio, an unsuitable structure can create problems with distributions, land tax, governance and future ownership changes.
Practical rule: Choose the trust for the ownership and decision-making problem you actually have. Don't choose a family trust simply because the name sounds familiar.
For a plain-language introduction, see Everglow's guide to what a family trust is in Australia.
What Each Trust Actually Is Under Australian Law
A unit trust is generally used where beneficiaries hold units that represent fixed interests in trust income and capital. The deed should set out those entitlements clearly. A fixed trust may give unitholders present entitlement to income and capital, rights connected with winding up, and interests that aren't removable or restricted by trustee discretion. NSW Revenue's practice note also identifies the possibility of only one class of units in a fixed trust context. Read the NSW Revenue practice note on fixed trusts before relying on a particular classification.
A discretionary trust gives the trustee power to select beneficiaries from a defined class and decide the amount each beneficiary receives. The trustee may distribute income to one beneficiary, divide it among several beneficiaries, or retain income where the deed and tax rules permit. Beneficiaries don't generally have a fixed entitlement before the trustee exercises that discretion.
The expression family trust has a specific tax meaning. A discretionary trust becomes a family trust for the relevant tax purposes only when the trustee makes a family trust election. That election identifies a test individual and defines the family group for the family trust rules. The ATO explains that family trust elections apply for specified income years and that related rules can involve interposed entities and distributions outside the family group. Its guidance on family trusts should be reviewed before an election is signed.
This creates an important technical point. A deed may be discretionary, but it isn't automatically a family trust for tax purposes. Conversely, the tax consequences can change once an election is made, and revocation can raise capital gains tax issues, including CGT event E4. The election is a governance decision, not a label to add casually after the deed is established.
Everglow's explanation of what a unit trust is in Australia provides a useful starting point, but the trust deed, asset type and intended beneficiaries still need professional review.
Control, Distributions and Present Entitlement
The central difference in unit trust vs family trust planning is control over economic outcomes. In a unit trust, ownership interests generally determine who is presently entitled to trust income. In a discretionary family trust, the trustee decides who receives a distribution, if anyone, within the boundaries of the deed and tax law.
The ATO states that income from a unit trust is included in a unitholder's assessable income for the year in which the unitholder is presently entitled to the trust income. Cash timing isn't the deciding factor. A person may need to include the amount even if the cash is paid later, depending on the trust's entitlement and distribution arrangements. The ATO determination on unit trust distributions sets out this distinction.
The following table summarises the operating difference.
| Feature | Unit Trust | Family (Discretionary) Trust |
|---|---|---|
| Control | Trustee administers the deed, while units generally define economic ownership. | Trustee selects eligible beneficiaries and distribution amounts. |
| Default entitlement | Generally fixed by the number and class of units held. | No automatic entitlement before the trustee exercises discretion. |
| Streaming ability | Depends on the deed, unit rights and tax rules. | May provide flexibility for capital gains, franked dividends and other income categories where legally available. |
| Annual resolution burden | Requires accurate entitlement records and proper documentation. | Requires careful annual resolutions, beneficiary identification and family-group compliance. |
A unit trust is usually the cleaner fit for unrelated investors, a property syndicate or a joint venture where each party expects a defined return linked to ownership. A family trust is usually more suitable for a family that wants to vary distributions between spouses, adult children and corporate beneficiaries as circumstances change.
Neither structure removes administration. Trust deeds, accounts, resolutions, beneficiary records and tax returns must align. The trust deed requirements explained by Everglow are particularly relevant where the proposed arrangement involves property, multiple investors or changing beneficiary classes.
Tax Outcomes and the Family Trust Distribution Tax Risk
Trust tax outcomes begin with the trust's net income, the deed and the beneficiaries' entitlements. A unit trust generally allocates income according to fixed unit holdings. If one investor holds a larger proportion of the units, that investor generally receives the corresponding share of distributable income, subject to the deed and tax rules.
A discretionary family trust gives the trustee more room to allocate income between beneficiaries. The trustee may consider each beneficiary's circumstances, other income and capacity to receive distributions. That flexibility can support family wealth planning, but it requires a properly documented decision and doesn't guarantee a particular tax result.
Capital gains, franked dividends and other categories of income can have distinct treatment. The deed must support the proposed streaming approach, and the trustee must satisfy the relevant tax requirements. The ATO's specific rules for some trusts should be considered where distributions or benefits may cross family-group boundaries.
The sharpest risk arises after a family trust election. If the trustee distributes income or provides a benefit outside the defined family group, family trust distribution tax may apply at the highest marginal tax rate plus the Medicare levy, payable by the trustee. This is not a minor adjustment. It can turn an otherwise ordinary distribution into a material compliance event.
A unit trust doesn't carry that family-group restriction merely because it has family unitholders. Its fixed entitlements can make ownership proportions more predictable. However, a unit trust can still create administrative problems if the deed, accounts and distribution records don't match.
For Dr Anya Sharma, a Sydney sole trader considering a trust for a medical investment property, the decision would depend on whether she expects to retain fixed ownership with another investor or wants family distribution flexibility. If she and a relative contribute according to defined proportions, a unit trust may better reflect the commercial bargain. If the assets are intended for family wealth and distributions may change over time, a discretionary trust may be more suitable, subject to advice on the election and beneficiary group.
The ATO's current trust distribution instructions also highlight the practical importance of beneficiary information, including TFNs and pre-fill data. Where a beneficiary doesn't provide a TFN, withholding at 47% may apply under the relevant rules. Clean resolutions and complete records now matter for both structures.

Land Tax, Migrant Clients and Practical Use Cases
Income tax isn't the only reason the structure matters. In New South Wales, Revenue NSW may classify a unit trust as a special trust, fixed trust or family unit trust. A family unit trust is treated as a fixed trust only if strict conditions are satisfied, including at least 95% of units being owned by the same family group, together with the relevant land and value requirements. The Revenue NSW trust classification guidance should be checked before acquiring NSW land.
That creates a classification cliff. Two trusts may hold identical property, yet receive different land-tax treatment because one has fixed qualifying entitlements and the other doesn't. A deed that works for income-tax purposes may not produce the desired NSW land-tax outcome.
Victoria and Queensland apply their own land-tax rules, thresholds and surcharge settings. A client moving between states, or holding property across several states, needs a state-by-state review rather than a national assumption.

Migrant and international clients need an additional layer of care. Overseas beneficiaries can affect withholding, residency analysis, trust migration questions, surcharge exposure and the timing of capital gains tax events. A temporary resident spouse or a beneficiary living overseas shouldn't be added to a deed or distribution resolution without checking the consequences first.
Three common decision contexts illustrate the difference:
- SMSF co-investment: A self-managed superannuation fund may prefer units where its entitlement to income and capital is documented by ownership. The structure still requires superannuation, tax and investment-strategy review.
- Blended-family wealth: A discretionary trust may offer flexibility where the family wants to manage distributions across changing relationships and generations. The trustee must still consider the deed, family group and asset-protection limits.
- Recently arrived investor: A new Sydney migrant with a temporary resident spouse may need advice on residency, land tax, beneficiary status and future exit consequences before settling on either structure.

Which Structure Fits Your Circumstances
Choose a unit trust when the commercial relationship depends on fixed ownership. It generally suits a joint venture where each participant contributes capital and expects distributions tied to units, a passive property syndicate with defined investors, or an SMSF investment requiring clear proportional entitlements. It can also make onboarding an unrelated investor more intelligible because the ownership agreement is visible in the unit register and deed.
Choose a family discretionary trust when the family needs controlled flexibility. A trustee may be able to distribute among spouses, adult children and companies in different proportions across years, subject to the deed and tax law. Families focused on intergenerational wealth, asset protection and changing income patterns may value that flexibility more than the simplicity of fixed percentages.
That flexibility comes with a price. A family trust election creates a defined family group, and distributions outside that group may attract FTDT. Annual resolutions must identify beneficiaries correctly, record the trustee's decision and support the tax treatment. A trust shouldn't distribute just because a family member needs cash. The trustee needs a defensible process.
A fixed ownership structure is usually stronger for a commercial partnership. A discretionary structure is usually stronger for family flexibility.
Migrant clients and families with overseas beneficiaries need further advice before settlement. Vesting, residency, CGT event E4, foreign resident withholding and state surcharge rules can change the outcome. The right structure depends on the family, asset mix, contributor relationships, intended distributions and time horizon, and it should be reviewed when those circumstances change.
The practical answer is simple: use a unit trust when fixed entitlements and ownership clarity are the priority, and consider a family trust when discretionary family distributions are the priority. The suitable choice still depends on your circumstances, and the deed and election should be reviewed before implementation.
