Fixed Trusts Explained: What Fixed Trusts Mean For Businesses And Investors

If you’re running a growing small business or investing alongside family members or business partners, you’ve probably heard the term “trust” thrown around as a way to hold assets, manage risk, or plan for the future.

But once you start looking into it, trusts can quickly become confusing - especially when people talk about different types of trusts, like discretionary trusts, unit trusts, and fixed trusts.

In this guide, we’ll break down what a fixed trust means in plain English, explain how a fixed trust works in Australia, and highlight the key legal and commercial issues you should consider before setting one up.

While a trust can be a powerful structure, the details matter. The way your trust is drafted and administered can affect control, distributions, and even your ability to bring in investors or exit later.

It’s also important to note that “fixed trust” can be a technical concept for tax purposes, and the tax treatment can depend on the trust deed and how the trust is operated. Sprintlaw can help with the legal structuring and documents, but you should also speak with your accountant or tax adviser about whether a particular trust will be treated as a “fixed trust” under the relevant tax rules.

What Is A Fixed Trust?

A fixed trust is a trust where the beneficiaries have fixed entitlements to the income and/or capital of the trust.

In practical terms, that usually means the trust deed sets out a clear formula for who gets what. The trustee doesn’t have a broad discretion to “choose” beneficiaries each year (unlike a discretionary/family trust).

Fixed Trust Meaning In Plain English

When people ask what a fixed trust is, a simple way to think about it is:

• the trust holds assets (like shares, property, or a business);
• the beneficiaries have defined rights to the trust’s income/capital; and
• distributions follow those defined rights, rather than the trustee’s discretion.

Many fixed trusts in Australia are unit trusts (where beneficiaries hold “units” similar to shares, and distributions are proportional to unit holdings). However, not every unit trust is automatically a fixed trust for all purposes - the trust deed, the nature of the entitlements, and how the trust is administered are what matter (and there can be technical tax rules in this area).

Who’s Who In A Fixed Trust?

Most trusts (including a fixed trust) involve these key roles:

• Settlor: the person who establishes the trust (usually by contributing a small initial amount). The settlor is typically not a beneficiary, and the details here matter for trust integrity.
• Trustee: the legal “owner” of trust assets who manages the trust and makes distributions according to the trust deed. The trustee can be an individual or a company.
• Beneficiaries: the people or entities who are entitled to benefit from the trust (for a fixed trust, those entitlements are set and defined).

If you’re using a company as trustee (which is common for risk management and administration), you may also need to think about your company set up and governance documents.

How Does A Fixed Trust Work In Practice For Small Businesses?

Fixed trusts are often used where you want clarity and certainty about who owns what - especially when there are multiple investors, business partners, or unrelated parties involved.

In a small business context, a fixed trust might be used to:

• hold the shares in an operating company (so ownership between founders/investors is clearly defined);
• hold business assets (like equipment, IP, or a property used by the business);
• hold an investment asset (like commercial property) where each investor contributes different amounts; or
• structure a joint venture where parties want predictable distribution and exit arrangements.

Why “Fixed” Can Be Helpful

For many small businesses, the main advantage of a fixed trust is predictability. When you’re bringing money in from other parties, people usually want to know:

• what percentage they own;
• what percentage of profits they’re entitled to;
• how decisions get made; and
• what happens if someone wants to exit or sell.

A well-drafted fixed trust can help answer those questions upfront - which can be essential when you’re trying to avoid disputes later.

Fixed Trust vs Discretionary Trust (At A High Level)

You’ll often hear fixed trusts compared with discretionary (family) trusts. Broadly:

• Fixed trust: distributions generally follow fixed entitlements (less flexibility, more certainty).
• Discretionary trust: trustee usually has discretion to distribute income/capital among beneficiaries (more flexibility, less certainty year-to-year).

Which is “better” depends on what you’re trying to do. If you’re aiming to attract investors or share ownership with non-family members, fixed entitlements can be easier to understand and negotiate.

What Are The Pros And Cons Of A Fixed Trust?

Like any structure, a fixed trust can be a great fit in the right scenario - but it’s not automatically the best option for every business.

Pros Of A Fixed Trust

• Clear ownership structure: Each beneficiary’s entitlement is usually defined, which can reduce misunderstandings.
• Easier to bring in investors: Investors often prefer defined rights (similar to shares or units) rather than a trustee’s discretion.
• More straightforward distribution expectations: If each party knows their percentage, it can feel “fair” and transparent.
• Potentially easier succession/exit planning: Depending on the trust deed, you can create mechanisms for unit transfers or buyouts.

Cons And Common Risks To Watch

• Less flexibility: Because entitlements are fixed, it may be harder to shift distributions year-to-year (which some business owners want for cashflow planning).
• Document quality matters: “Fixed” outcomes rely heavily on the drafting of the trust deed and any accompanying agreements.
• Disputes can still happen: Even with clear entitlements, problems arise around control (who appoints/removes the trustee, who makes decisions, what approvals are required).
• Compliance and administration: Trusts need to be run properly, with correct records and resolutions.

One important point: a trust structure isn’t just a “set and forget” arrangement. Your bookkeeping, resolutions, and distribution processes should match what your deed says, otherwise you may create legal and tax issues.

Key Legal And Commercial Issues To Get Right In A Fixed Trust

When a fixed trust is being used for business ownership or investment, the risk usually isn’t the concept - it’s the fine print.

Here are the main areas to think through early.

1. The Trust Deed (Your Rulebook)

The trust deed sets out:

• who the beneficiaries are (and whether new beneficiaries can be added);
• how income and capital are dealt with;
• what the trustee can and can’t do;
• how meetings/resolutions happen; and
• how the trust can be varied or wound up.

If your business strategy is to bring in investors, reinvest profits, or buy/sell assets, you want the deed to support that - not accidentally restrict it.

2. Trustee Choice: Individual vs Corporate Trustee

The trustee is the legal owner of trust assets, so the trustee structure matters for risk and administration.

• Individual trustee: simpler and cheaper to set up, but can carry higher personal risk and can become messy if trustees change.
• Corporate trustee: often preferred for asset-holding and business structures because it can help separate personal risk from trust operations and make trustee changes easier (through changing directors rather than changing the trustee’s legal identity).

If you use a corporate trustee, you’ll usually want the company’s governance documents aligned with the trust’s control arrangements, including a tailored Company Constitution where appropriate.

3. Control: Who Really “Runs” The Trust?

Even in a fixed trust, control doesn’t always sit with the people who hold entitlements.

Control is often determined by:

• who is the trustee (and who controls the trustee, if it’s a company);
• who has the power to appoint/remove the trustee (often called the “appointor” in some trust structures); and
• what decisions require beneficiary consent (if any).

This is where many disputes begin - for example, where one party believes they “own” 50% because of entitlement, but another party effectively controls decisions through the trustee role.

4. Unitholder/Beneficiary Arrangements (Especially For Unit Trusts)

If your fixed trust is structured as a unit trust, you’ll usually want a separate agreement to cover commercial terms that the deed alone may not handle in a business-friendly way.

That’s where an Unitholders Agreement can be useful - for example, to address:

• how new units can be issued (and at what price);
• how distributions are determined and paid;
• transfer restrictions (so units can’t be sold to a stranger without approvals);
• what happens on default, death, or incapacity; and
• deadlock and dispute resolution processes.

In other words, it helps you treat the trust like an investable structure, rather than a loose arrangement that only works while everyone is getting along.

5. Identity And Registration: ABN, TFN, And The Basics

Trusts often need their own registrations to operate properly, and this is frequently overlooked early on.

As part of your setup, you’ll want to confirm the trust requirements that apply to your structure, including whether the trust needs an ABN and TFN, and how the trustee should be identified in contracts and accounts.

This is especially important if the trust will:

• open bank accounts;
• sign leases;
• issue invoices; or
• buy and sell assets.

When Is A Fixed Trust The Right Fit (And When Isn’t It)?

A fixed trust can be a strong option, but it’s usually best in scenarios where certainty is a priority and the stakeholders want defined rights.

Common Situations Where A Fixed Trust Works Well

• Joint investments: If two or more parties are contributing different amounts and want distributions to reflect that contribution.
• Business partners who aren’t family: Fixed entitlements can feel more “commercial” and easier to negotiate.
• Investment property ownership: Particularly where you want clear proportional entitlement.
• Holding structures: Where you want the trust to hold shares or assets and have predictable ownership proportions.

Situations Where You Might Consider A Different Structure

• You want maximum flexibility year-to-year: If your priority is the ability to allocate distributions differently depending on business needs, a discretionary structure may be considered (subject to advice).
• You want very simple administration: Trusts can be more complex than holding assets in your personal name or in a simple company structure.
• You need a “bare” holding arrangement: In some transactions (especially property), a bare trust might be used for a very specific purpose where the trustee has limited discretion and acts mainly as a holder of legal title.

If you’re unsure, it’s worth stepping back and clarifying your goals first: are you trying to attract capital, protect assets, split profits, plan succession, or manage liability? The “right” trust structure usually follows from that.

How Do You Set Up A Fixed Trust (Without Creating Problems Later)?

Setting up a fixed trust isn’t just about downloading a template deed and moving on. If the trust is going to hold valuable assets or underpin your business ownership, getting the structure right early can save you time, money, and disputes down the track.

Step 1: Define The Commercial Deal First

Before drafting anything, be clear on the basics:

• Who is contributing what (cash, assets, IP, services)?
• What percentage should each party effectively own?
• Will profits be distributed regularly or reinvested?
• Who makes decisions and what decisions require unanimous approval?
• What happens if someone wants to exit?

If you can’t answer these questions comfortably, drafting a trust deed will not “solve” the uncertainty - it will usually lock it in.

Step 2: Choose The Trustee Structure

This is a legal and risk decision as much as an administrative one.

If you opt for a corporate trustee, you’ll generally need to incorporate a company, appoint directors, and ensure your documents reflect who controls the trustee.

Step 3: Prepare The Trust Deed (And Any Supporting Agreements)

This is where the fixed trust is created in legal terms.

Depending on the trust’s purpose, you may also need supporting documents (like unitholder arrangements, subscription terms for new investors, or asset transfer documentation).

Step 4: Put The Trust Into Operation Properly

After setup, you should ensure the trust is operated consistently with the deed. This typically includes:

• opening bank accounts in the correct name;
• signing contracts correctly (trustee “as trustee for” the trust);
• keeping trust records and resolutions; and
• distributing income correctly (and documenting those decisions).

If the trust has an accountant involved (which is common), it still helps for your legal structure and your accounting treatment to align - because mismatches can cause major headaches later.

Key Takeaways

• A fixed trust is a trust where beneficiaries have fixed entitlements to income and/or capital, usually set out clearly in the trust deed.
• Fixed trusts are often used for business and investment arrangements where you want clear ownership proportions and predictable distributions.
• The biggest risks usually come from poor drafting or unclear control arrangements - especially around the trustee, decision-making powers, and exit rules.
• For unit trust-style fixed trusts, an Unitholders Agreement can help document practical commercial terms that reduce disputes.
• Getting registrations and administration right (ABN/TFN, correct contracting name, records and resolutions) is essential for the trust to work as intended.
