Unit Trust Vs Family Trust: Which Suits Your Business in Australia?

If you’re weighing up the best way to own business assets, distribute profits tax‑effectively and protect your personal assets, a trust is often on the shortlist.

For Australian small businesses, the most common options are a family (discretionary) trust and a unit trust.

Both can work well, but they behave differently when it comes to control, profit distribution, admitting investors and exiting down the track. Choosing the wrong fit can create headaches later - especially if you plan to grow, bring in partners or sell.

In this guide, we’ll break down unit trust vs family trust in plain English, highlight the key differences for small business owners, and outline the legal steps to set things up the right way.

What Is A Trust And Why Do Businesses Use One?

A trust is a legal arrangement where a trustee holds and manages assets for the benefit of others (the beneficiaries). In business, those assets are often shares in a trading company, business IP or property.

Why use a trust?

  • Asset protection: separating business risk from personal assets.
  • Tax flexibility: distributing income to beneficiaries (subject to tax advice).
  • Succession: controlling how assets pass to family members over time.
  • Investment: pooling funds from family members or unrelated investors.

If you’re considering a trust primarily for risk management and wealth planning, it’s worth reading this broader overview of trusts in Australia.

How Does A Family (Discretionary) Trust Work?

A family trust (often called a discretionary trust) gives the trustee discretion over how to distribute income and capital among a defined “family group” of beneficiaries each year.

Key features

  • Discretionary distributions: the trustee can choose who gets what and when, within the rules set out in the trust deed.
  • Family control: typically used by a single family unit for owning business assets or investments.
  • Flexibility: useful for tax planning within the family group (tax advice required).
  • Harder to admit outsiders: bringing in non-family investors usually isn’t practical without restructuring.

When family trusts are commonly used

  • Owning the shares of a trading company for a family-run business.
  • Holding passive investments (e.g. managed funds, property) for a family group.
  • Where the founders want maximum flexibility to decide distributions each year.

Most family trusts are governed by their trust deed. Getting the trust deed right up‑front is critical - it sets the rules about eligible beneficiaries, trustee powers, appointment/removal of the trustee, and how income is determined.

How Does A Unit Trust Work?

A unit trust looks and feels more like a “fixed” structure. Beneficiaries hold units (like shares), and distributions typically follow unit holdings.

Key features

  • Fixed entitlements: unitholders receive income/capital in proportion to their units (subject to the deed).
  • Investor‑friendly: easy to bring in new investors or vary ownership by issuing or transferring units.
  • Clear valuation: units can be valued and sold, supporting buy‑ins/buy‑outs.
  • Less distribution discretion: the trustee doesn’t have the same flexibility as a discretionary trust.

When unit trusts are commonly used

  • Joint ventures between unrelated parties who want clear, fixed entitlements.
  • Startups or SMEs aiming to admit investors without changing the trading company’s cap table.
  • Property syndicates or projects pooling capital from several unitholders.

Because ownership is fixed by units, unit trusts are often easier to explain to outside investors. They can also work well where multiple families run one business and want clear percentages and exit pathways.

Unit Trust Vs Family Trust: Key Differences For Small Businesses

So, which suits a small business better? It depends on how you’ll own the business, distribute profits and grow over time. Here are the factors owners usually care about.

1) Control and flexibility

  • Family trust: the trustee can choose who receives income each year. This flexibility can be powerful for family planning, but harder to apply when unrelated investors are involved.
  • Unit trust: distributions largely follow unit holdings, offering less flexibility but more predictability for investors.

2) Admitting new owners

  • Family trust: not designed for unrelated investors. You typically can’t just “sell 10%” to an outsider without complex workarounds.
  • Unit trust: straightforward to issue or transfer units to new investors at an agreed valuation.

3) Exits and buy‑outs

  • Family trust: exiting a beneficiary is not like transferring shares; it can be difficult to crystallise value for one person in a discretionary framework.
  • Unit trust: units can be transferred, redeemed or bought back under the deed - supporting planned exits and valuation mechanisms.

4) Profit distribution

  • Family trust: trustee discretion (within deed rules) can help with family tax planning (seek tax advice each year).
  • Unit trust: generally proportionate to units - simpler and more “fixed”, which investors often prefer.

5) Banking and third‑party comfort

  • Family trust: banks are familiar with discretionary trusts but may scrutinise beneficiary control and trustee guarantees.
  • Unit trust: the fixed nature may assist when negotiating investor terms and finance, as entitlements are clearer.

6) Practical growth considerations

  • If you plan to keep ownership within one family and value flexibility, a family trust is often a fit.
  • If you expect to bring in partners or outside capital, a unit trust usually makes this smoother.

Many small businesses also use a corporate trustee (a proprietary limited company as trustee) to add an extra liability shield. If you’re considering that route, it’s worth aligning your trust decision with your Company Set Up from day one.

Which Structure Should You Choose? Common Scenarios

Different businesses will lean different ways. Here are typical scenarios we see and how the structures stack up.

Scenario 1: Family‑owned services business

You and your partner run a consultancy and want to distribute profits across family members as your circumstances change.

  • Leaning towards: Family trust (discretionary distributions across a family group can be helpful, subject to tax advice).
  • Watch outs: If you later want to admit a non‑family co‑founder, you may need to restructure.

Scenario 2: Two unrelated founders starting a product brand

You both want clear 50/50 ownership and the option to bring in a third investor on defined terms.

  • Leaning towards: Unit trust (fixed entitlements and simpler investor buy‑in via units).
  • Watch outs: Make sure the trust deed covers unit issues, transfers, pre‑emptive rights and valuation methods.

Scenario 3: Property or project syndicate

A group of friends pool funds to purchase a premises the trading business will occupy.

  • Leaning towards: Unit trust (each investor holds units that reflect their contributions, with distributions proportionate to units).
  • Watch outs: Document decision‑making and exit mechanics clearly in the deed.

Scenario 4: Holding company shares for asset protection

You want to hold the shares in your trading company via a trust for asset protection and succession purposes.

  • Leaning towards: Family trust if ownership will stay within a family group; unit trust if you anticipate external investors.
  • Useful read: how beneficial ownership through a trust works when holding company shares.

Once you’re clear on unit trust vs family trust, the next step is getting the legal foundations right. A strong setup saves time, cost and risk later.

1) Map your structure

Decide what the trust will own (e.g. shares in the trading company, IP, property) and whether you’ll use a corporate trustee. Many owners choose a company as trustee to help separate liability - plan this alongside your Company Set Up.

2) Draft and execute your trust deed

The trust deed is the rulebook. It should be carefully tailored to your goals, including:

  • For family trusts: class of beneficiaries, how income is determined and distributed, appointor powers, and succession arrangements.
  • For unit trusts: unit classes, issue/transfer/redemption procedures, pre‑emptive rights, valuation method and governance.

Because a trust deed is a deed, execution formalities matter. If you’re unsure about witnessing requirements, this short guide on who can witness a signature will help you avoid technical mistakes.

Over time, it’s common to tweak the rules to reflect how your business evolves. Where your deed allows it, a Deed of Variation can update terms (for example, to introduce new unit classes or clarify distribution provisions).

3) Understand the required registrations

Trusts in Australia interact with several identifiers and registrations, often including a TFN and ABN for the trust, and an ACN if you’re using a corporate trustee. Our overview of trust requirements explains how these fit together, and when each number is needed.

4) Document decision‑making and ownership

For unit trusts, keep a current register of unitholders and minutes/resolutions for unit issues or transfers. For family trusts, ensure trustee resolutions are made and stored each year to support distributions according to the deed.

5) Align your operating company documents

If the trust owns shares in a trading company, don’t forget the company’s internal rules. A robust Company Constitution and, where there are multiple founders, a Shareholders Agreement (so the people behind the trust are aligned) will help keep governance tight.

6) Day‑to‑day contracts and compliance

The trust is often a holding vehicle while the operating company does the trading. Make sure your customer contracts, IP ownership arrangements and employment documents are consistent with the structure. For example, ensure IP is licensed or assigned to the right entity and that the trustee is named correctly where it is the contracting party.

7) Keep an eye on distributions, tax and records

Trust distribution decisions are typically made annually. It’s important to follow your deed’s process for determining income, making valid resolutions and preparing beneficiary statements. That paper trail matters for both legal and tax reasons.

If at some point you need to transfer assets in or out of the trust (for example, an asset moving to a unitholder as part of a restructure), speak with your advisors early. In some cases, an in‑kind transfer is treated as an in specie distribution - the deed must permit it and you’ll need to consider duty and tax.

  • Trust Deed: Sets the rules for your trust, including beneficiaries/unitholders, powers and distribution mechanics. Execution formalities are important because it’s a deed.
  • Deed of Variation: Lets you amend the trust deed where permitted by the original deed and applicable law.
  • Unitholders Register and Unit Certificates (Unit Trusts): Records legal ownership, transfers and unit classes.
  • Trustee Resolutions: Evidence of annual distribution decisions and key actions taken by the trustee.
  • Company Constitution (Corporate Trustee or Trading Co): Governs company decision‑making and board/shareholder processes.
  • Shareholders Agreement (Trading Co): Aligns owners (including trusts) on governance, transfers, vesting and exits.
  • IP Assignment/Licence: Ensures the right entity owns or uses your brand and IP assets.

If you’re unsure whether a particular change requires a deed or a standard agreement, revisit the basics of what makes a deed different from a contract so you use the correct instrument.

Common pitfalls (and how to avoid them)

  • Using the wrong party name: Make sure contracts name the trustee “as trustee for” the trust, not the trust alone (which isn’t a separate legal entity).
  • Missing distribution resolutions: Keep timely, valid trustee resolutions to support how income is allocated.
  • Deed misalignment: If your actual practices (e.g. how you calculate income) don’t match the deed wording, get advice and consider a Deed of Variation.
  • Investor uncertainty: For unit trusts, be explicit about unit classes, pre‑emptive rights and valuation methods to prevent disputes on exit.
  • Ignoring registrations: Confirm the correct trust ABN/TFN and any ACN for a corporate trustee as part of your trust requirements.

Key Takeaways

  • A family trust gives the trustee discretion to distribute income among a family group, offering flexibility for family‑owned businesses but making outside investment harder.
  • A unit trust gives beneficiaries fixed entitlements via units, making it easier to admit investors, manage buy‑ins/buy‑outs and value ownership stakes.
  • Choose the structure that matches your growth plans: family‑only control and flexibility often points to a family trust; investor‑friendly ownership often points to a unit trust.
  • Get the foundations right with a tailored trust deed, the right trustee (often a company), and clear rules on distributions, transfers and exits.
  • Keep your records, resolutions and registrations in order - especially annual distribution decisions and unitholder registers (for unit trusts).
  • If your business is owned through a trust, align your operating company documents (Company Constitution, Shareholders Agreement, IP arrangements) so governance and ownership are clear.
  • When in doubt, seek advice early - small deed tweaks and setup decisions can save major costs later.
