A Melbourne sparkie with a growing contracting business and a Brisbane family building a property portfolio can face the same question: should the next structure be a unit trust or a discretionary trust? The answer affects who owns the assets, who receives income, how much control the trustee has, and how much paperwork lands on the accountant's desk.
The choice has become more important in 2026. The Australian Taxation Office is changing trust reporting mechanics, including new trust tax return labels and the end of the separate TFN report after a beneficiary quotes their TFN from 1 July 2026, as outlined in its 2026 trust distribution guidance. The ATO has also announced a proposed 30% minimum tax on discretionary trusts from 1 July 2028, subject to the policy's operation and final legislation, in its minimum tax announcement.
This is a practical Australian guide to the unit trust vs discretionary trust decision. It focuses on the mechanics that matter to tradies, property owners, family businesses and SME partners, so you can choose a structure that still makes sense beyond the current financial year.
Why Australian Small Business Owners Are Comparing These Two Trusts Right Now
A tradie taking on a business partner and an SME buying its first investment property can face very different consequences from choosing the wrong trust. A unit trust fixes the economic split through units. A discretionary trust gives the trustee control over eligible income and capital distributions. The right structure depends on whether ownership certainty or distribution flexibility matters more over the next three years.
A unit trust divides ownership into units, with rights set by the deed. An investor holding half the units will generally have half the trust's income and capital entitlement. That suits unrelated investors, joint ventures and businesses where each party expects a defined share. The trustee administers the assets, while the deed and unit register record the economic arrangement.
A discretionary trust, often called a family trust, names a class of potential beneficiaries but does not give each person a fixed annual share. The trustee decides which beneficiaries receive income or capital and how much, subject to the deed and tax rules. That flexibility can suit a family business, but it requires timely resolutions and reliable records.
Treasury and budget material records more than 1 million trusts in Australia, including around 840,000, about 80%, classified as discretionary trusts. It also records $142.4 billion distributed by discretionary trusts in 2022–23, with average annual income growth of 7.8% since 2011–12. See the Treasury and budget tax explainer on discretionary trusts.
The announced proposal for a 30% minimum tax on discretionary trusts from 1 July 2028, if legislated, would change the calculation. The 2026 reporting changes also make accurate beneficiary information and distribution records more important.
Practical rule: Choose the structure for the ownership and distribution problem you expect in three years, not only this year's tax return.
How a Unit Trust and a Discretionary Trust Actually Work
Start with the legal mechanics, not the tax rate.
A unit trust issues units to beneficiaries or investors. The trust deed sets out the rights attached to each class of unit, including rights to income, capital and voting. The trustee records ownership in a unit register, and distributions normally follow the registered holdings.
If a couple owns units equally, the trust generally can't give all annual income to one partner because that partner has a lower marginal tax rate. The fixed entitlement follows the units. Changing the economic split usually requires a legitimate transfer or issue of units, compliance with the deed, and consideration of tax, stamp duty and financing consequences.
A discretionary trust gives the trustee a different role. The deed names or defines the beneficiary class, but it doesn't give each beneficiary a fixed annual share. The trustee, often a corporate trustee, reviews the trust's income and resolves which beneficiaries receive distributions. The appointor generally holds the power to remove and replace the trustee, so control requires careful succession planning.
Structural snapshot
| Feature | Unit Trust | Discretionary Trust |
|---|---|---|
| Ownership evidence | Unit register and trust deed | Trust deed, trustee powers and beneficiary class |
| Income entitlement | Usually fixed according to units | Created through the trustee’s valid resolution |
| Capital entitlement | Usually fixed according to units | Trustee distributes within deed powers |
| Decision-maker | Trustee administers, but units drive economic rights | Trustee decides allocations |
| Beneficiary certainty | High for registered unit holders | Potential right only until discretion is exercised |
| Best fit | Co-investment, property ventures and predictable profit sharing | Family wealth, succession and changing distributions |
| Control | Unit holders may have deed-based voting rights | Appointor and trustee control the trust’s administration |
A unit trust therefore resembles a company in one important respect, ownership has a measurable proportion. A discretionary trust resembles a family planning vehicle, the trustee can respond to changing family circumstances, provided the deed permits the decision.

Tax Outcomes That Drive the Unit Trust vs Discretionary Trust Decision
The structure determines who is entitled to trust income, when that entitlement arises and how much distribution flexibility the trustee has.
With a unit trust, the deed and unit holdings usually determine each unitholder's share. Public unit trust arrangements commonly provide quarterly or half-yearly distributions, but tax generally follows present entitlement, not the date cash reaches the investor. A unitholder usually includes their share of net trust income in assessable income for the relevant year. The ATO explains this treatment in Income Tax Ruling IT 2680.
That makes a unit trust suitable where co-owners need predictable allocations. A corporate beneficiary may receive its fixed share, including relevant franked dividend and capital-gain components, subject to the deed and tax rules. Individuals receiving unfranked income must apply their own marginal tax position. The 47% rate can apply where the law imposes the top marginal rate, including family trust distribution tax in the circumstances covered by the ATO's family trust guidance.
Discretionary trust timing
A discretionary trust gives the trustee broader distribution choices, but those choices must be documented and completed on time. The ATO states that a trustee resolution intended to make beneficiaries entitled to trust income for an income year must be made by 30 June, and the entitlement must be indefeasible, meaning it cannot later be withdrawn. The ATO resolutions checklist sets out the timing requirement.
Family trusts carry a separate compliance risk. A distribution outside the relevant family group can trigger family trust distribution tax at 47%, according to the ATO's 2026 trust guidance. A distribution to a company, relative or associate therefore needs checking against the trust's election, family group and deed before the resolution is signed.
Capital gains need the same discipline. A trust may distribute a capital gain with its character, and an eligible beneficiary may access the 50% active asset discount when the relevant conditions are met. Check the deed, beneficiary status, holding period and small business CGT rules. Discretionary powers do not allow a trustee to stream every gain automatically.
| Tax Issue | Unit Trust | Discretionary Trust |
|---|---|---|
| Annual allocation | Usually follows fixed unit entitlements | Trustee must make valid allocations |
| Tax timing | Present entitlement generally follows the deed and unit rights | Resolution must be made by 30 June |
| Family group risk | Fixed ownership supports clearer allocation | Outside-family distributions can attract 47% family trust distribution tax |
| Capital gains | Components generally flow by fixed entitlement | Trustee allocates within the deed and tax law |
| Retained income outlook | No equivalent announced minimum-tax rule applies merely because it is a unit trust | Proposed 30% minimum tax from 1 July 2028 if legislated, not yet law |
| Main weakness | Limited income-splitting flexibility | Greater timing, documentation and beneficiary-class risk |
The ATO's technical explanation of present entitlement requires income to be legally available, the beneficiary to hold an absolutely vested beneficial interest in possession, and the beneficiary to be able to recover it from the trustee. The ATO ruling on present entitlement is central when reviewing either structure.
For a practical explanation of distributions and trust tax returns, read this guide to the tax treatment of trusts. Tradies retaining profits for equipment or SMEs expecting changing family distributions should choose with the proposed 2028 rule in view, not just the current tax year.
Asset Protection, Control and Distribution Flexibility
A unit trust doesn't automatically protect assets better than a discretionary trust. It creates clearer ownership, but that clarity can also expose a unitholder's economic interest to creditors, bankruptcy claims or relationship-property disputes.
The trustee owns the trust assets legally. However, a unitholder owns a defined beneficial interest represented by units. A creditor may therefore target the unitholder's units or distributions, subject to the facts and applicable law. The trustee also can't normally redirect income away from the registered unit holders merely because one investor has personal financial trouble.
A discretionary trust gives the trustee more room to protect vulnerable beneficiaries. The trustee may decide not to distribute to a beneficiary facing bankruptcy, litigation or financial mismanagement, provided the deed and fiduciary duties support the decision. That flexibility doesn't make the trust immune from attack. A creditor of the appointor may create a control problem, and poor separation between personal and trust affairs can weaken the intended protection.
Control needs a deliberate design
A corporate trustee often makes sense for a discretionary trust because it separates the trustee role from the individual's personal name and simplifies succession when directors change. It doesn't eliminate liability, and directors still need to act properly.
Many advisers also recommend a corporate trustee for a unit trust, particularly where the trust will hold property or operate a business. The company can provide cleaner administration, but it won't turn a risky transaction into a protected one. Insurance, solvency, guarantees, correct bookkeeping and properly documented transactions remain essential.
| Dimension | Unit Trust | Discretionary Trust |
|---|---|---|
| Ownership | Fixed and measurable | No fixed beneficiary ownership before a resolution |
| Creditor exposure | A unitholder’s units may be relevant to creditors | Control rights and distributions require separate analysis |
| Income control | Follows unit proportions | Trustee chooses eligible recipients |
| Vulnerable beneficiaries | Limited ability to redirect a fixed share | Trustee may withhold distributions if deed and duties permit |
| Succession | Transfer units under deed and law | Appointor succession is critical |
| Governance | Strong fit for co-investors who need certainty | Strong fit for families needing changing outcomes |
The discretionary trust structure guide is useful for understanding the difference between potential beneficiary rights and fixed unit ownership.
Real-World Examples for Tradies and Property-Holding SMEs
Mike's electrical contracting business
Mike runs a Western Sydney electrical business through a Pty Ltd and earns $185,000 through the company. He wants to share business wealth with his wife and adult children, while keeping the structure workable if the proposed 2028 policy takes effect.
A unit trust with fixed 50/50 holdings gives Mike and his wife a clear economic split. The trustee allocates income according to the units, and the register provides a straightforward ownership record. That arrangement suits them if they want equal ownership and predictable distributions. It doesn't let them switch the split each year because one family member has a lower taxable income.
A discretionary trust gives the trustee a wider distribution choice among eligible beneficiaries. The trustee can consider each person's circumstances, but the resolution must be valid, timely and supported by records. Mike also needs to monitor family trust election settings, company entitlements and Division 7A exposure. The ATO requires action before the private company's tax return is lodged, or by its lodgment due date, where an unpaid present entitlement creates a Division 7A issue. The ATO guidance on Division 7A trust entitlements sets out the available payment, asset-transfer and complying-loan pathways.
The Nguyen family's property portfolio
The Nguyen family owns two investment properties through a unit trust. Their priority is clean proportional ownership if one family member later transfers an interest or another investor joins. The unit register makes the economic split visible, although the family must review state land tax and trust surcharge rules.
Victoria provides a useful warning. The Victorian State Revenue Office guidance on trusts and land tax states that unit trusts generally face trust surcharge rates unless the trustee completes the required notification or nominates a single principal place of residence beneficiary.
Moving the properties to a discretionary trust could improve succession flexibility and help the trustee respond to vulnerable beneficiaries. It may also create transfer, duty, refinancing and tax consequences. The family shouldn't restructure merely because a discretionary trust sounds more protective.
Setup Costs, Ongoing Compliance and 2026 Reporting Changes
Setup cost depends on the deed, trustee company, advice and transaction complexity. A basic discretionary trust deed may cost $1,500 to $3,500, while a unit trust deed may cost $2,000 to $5,000. A corporate trustee can add around $500 for ASIC registration. These are market estimates, not ATO figures, so obtain a fixed quote before signing.
Both structures require a trust deed, TFN registration, accounting records, a separate trust tax return and evidence that the trustee acted within the deed. A unit trust also needs unit issue records, transfer documents and a current unit register. A discretionary trust requires annual distribution analysis, beneficiary checks, trustee minutes and a resolution consistent with the deed.
The 2026 administration shift
The 2026 changes raise the standard for trust records. The ATO has introduced new trust return labels and says the separate TFN report will end after a beneficiary quotes their TFN from 1 July 2026, as explained in its 2026 trust instructions.
For a discretionary trust, the 30 June resolution deadline remains the pressure point. A document signed after year-end does not fix a decision the trustee failed to make on time. Prepare an income estimate, check the deed, identify eligible beneficiaries and record the resolution before the deadline.
| Cost or Obligation | Unit Trust | Discretionary Trust | 2026 Change |
|---|---|---|---|
| Deed | Often higher where unit classes and investor rights need drafting | Depends on beneficiary classes and trustee powers | Review wording before new reporting labels apply |
| Corporate trustee | Common for property and business ownership | Common for succession and separation | Keep ASIC and company records current |
| Annual allocation | Unit register and accounts support fixed allocations | Trustee resolution and minutes required | 30 June timing remains critical |
| Tax return | Separate trust tax return | Separate trust tax return | New trust return labels apply |
| TFN reporting | Follow ATO transition instructions | Follow ATO transition instructions | Separate TFN report ends after the stated 1 July 2026 change |
| Main administration risk | Incorrect issue, transfer or distribution of units | Late or defective distribution resolution | Update checklists and accounting workflows |
For tradies with stable ownership shares, the unit trust's register can justify the extra issue and transfer administration. For an SME family group changing distributions between beneficiaries, the discretionary trust demands more annual work and stronger minute-taking. That choice should account for the proposed 30% minimum tax from 1 July 2028, subject to final legislation, rather than relying only on today's flexibility.
Trustees should test whether a family trust election supports the intended distributions. The ATO says the election depends on fixed entitlements, directly or indirectly, to all income and capital for the specified individual and family group. That requirement often fits fixed unit holdings more naturally than broad discretionary rights.
Which Structure Suits Your Situation in 2026 and Beyond
A solo tradie with stable ownership shares usually needs certainty, not annual discretion. A family group with changing beneficiary needs has a different problem. My recommendation is direct: choose a unit trust when ownership certainty matters more than distribution flexibility. Choose a discretionary trust when succession, family control or changing beneficiary outcomes justify the extra compliance.
| Reader Profile | Better Structure | Why It Fits in 2026+ | Watch-Out Given 2028 Rules |
|---|---|---|---|
| Solo tradie wanting a stable family split | Unit trust | Fixed holdings make profit sharing easier to evidence | Changing allocations require changes to ownership |
| Family property group planning succession | Discretionary trust | Trustee can respond to family circumstances | Retained or affected income could face proposed minimum-tax settings |
| Couple operating an SME with predictable shares | Unit trust | Clear ownership supports governance and investor discussions | Fixed percentages can become restrictive |
| Blended family or business partners expecting conflict | Discretionary trust, with strong governance | Trustee powers can prevent automatic allocations | Appointor control and deed drafting need careful planning |
| Growth-stage operator retaining substantial trust income | Review both, with unit trust seriously considered | Fixed entitlements may provide cleaner governance | The proposed 2028 policy could reduce the discretionary advantage |
The announced proposal deserves attention now. Under it, a 30% minimum tax could apply from 1 July 2028 to discretionary trusts holding more than $5 million or earning above the relevant threshold, if the measure is enacted as described. This is a planning risk, not a current tax bill. Model the effect before committing retained income to a discretionary trust, then revisit the assumptions when legislation and thresholds are settled.
For a tradie partnership or SME couple with predictable shares, I favour a unit trust or company. The fixed ownership record matches the commercial arrangement and makes disputes over entitlement less likely.
For a family property group, blended family or business with genuine succession and beneficiary-management needs, I still favour a discretionary trust. Use a corporate trustee, define appointor powers carefully, document each annual decision and test the structure over a three-year tax model.
The right choice is the one that still works after the proposed 2028 change, not merely the one that produces the most flexibility today.
Frequently Asked Questions and Next Steps With EndureGo Tax
Can a discretionary trust hold units in a unit trust?
Yes. A discretionary trust can hold a fixed investment in a separate unit trust. Before setting this up, review both deeds, tax consequences, control arrangements, financing and duty implications.
Do unit trusts need a family trust election?
Not automatically. The answer depends on the distribution pattern and the beneficiaries involved. A family trust election may matter where distributions involve minors or other family trust rules, so it is not a standard unit trust requirement.
What happens if a discretionary trust earns no income?
Under the proposal, the 2028 minimum tax would not be triggered below the relevant threshold if enacted. A trust with no income generally does not need a distribution resolution for income it did not earn. The trustee must still keep records and lodge the required return or relevant notifications.
Is a corporate trustee worth the extra cost for a unit trust?
Usually, yes, if the trust owns property or operates a business. A corporate trustee can support succession, administration and some CGT rollover planning. It does not replace insurance, solvency controls or accurate records.
