Family wealth structures are not wealth. They are containers for it — and the container you choose quietly shapes how much of your income you keep, how protected your assets are, and what eventually reaches the next generation.
Most high-income couples hit a moment where someone tells them they “need a trust” or “should set up a company.” Usually it is a friend at a barbecue, an accountant in passing, or a confident stranger in a forum. The advice often lands with real force, yet it rarely comes with a reason. As a result, plenty of Australian families end up paying to build a structure they do not understand — and sometimes do not need.
This article strips the jargon out of the three family wealth structures Australians actually use: the family trust, the company, and superannuation (including an SMSF). Above all, it explains what each one is genuinely for, and who each tends to suit. Think of them not as clever tricks, but as tools with a job to do.
A structure is a container, not a strategy. The wealth still has to be built. The structure simply decides who holds it, how it is taxed, and how well it is protected.
The three containers at a glance
Notice that none of those descriptions mentions “getting rich.” That is deliberate. A container does not create the water it holds. Consequently, the first question is never “which structure?” — it is “what am I trying to do?”
01 The family trust — flexibility and protection
A discretionary (family) trust is essentially a legal arrangement where a trustee holds assets for a group of beneficiaries — usually you, your partner, and your children. Importantly, the trustee decides each year who receives the income. Because family members often sit on different tax rates, that flexibility can meaningfully reduce the household’s overall tax bill.
In addition, a trust offers a layer of asset protection. Since the assets are held by the trust rather than by you personally, they can be harder to reach if you are sued or a business fails. For professionals and business owners carrying personal liability, that separation matters. However, a trust is not a magic shield, and it will not protect against everything.
Important: the income splitting rules are changing
Here is the most important development in this space for years. In the 2026–27 Federal Budget, the Government announced a 30% minimum tax on discretionary trusts, proposed to start on 1 July 2028. Under the announcement, the trustee would pay at least 30% on the trust’s taxable income. Beneficiaries other than companies would then receive a non-refundable credit for that tax.
The practical effect is significant. Distributing to a low-income beneficiary — a non-working spouse, or an adult child at university — would no longer produce the saving it does today, because the credit cannot be refunded below 30%. In other words, the classic income splitting play is squarely the target. Treasury has released a consultation paper and submissions close on 31 July 2026.
Proposed — not yet law
The 30% trust minimum tax is an announced measure that has not been legislated. The rate, the start date, and the fine detail could all still shift through consultation. Accordingly, this is a reason to review your structure — not to tear it up. Some carve-outs are already flagged, including primary production income, fixed and widely held trusts, complying super funds, and testamentary trusts already in existence on 12 May 2026.
Crucially, one thing is not changing. Asset protection remains a real and durable reason to hold a trust. Therefore, if your trust exists to shield assets from business risk, it still does that job. If it exists mainly to split income, however, its purpose is being quietly rewritten beneath you.
Where a trust still genuinely fits
So what survives? Above all, protection and control. A trust remains a strong container where business or professional liability is real, where you want to control who receives what and when, and where succession across generations matters. Notably, the announced measure also leaves some ground untouched — primary production income, for instance, is flagged for exclusion.
Meanwhile, one classic misuse is worth flagging regardless of the reforms. A trust is usually the wrong home for a single negatively geared property. Why? Because a trust cannot pass its losses out to you — those losses are trapped inside the trust until it earns income to offset them. In contrast, holding that property in the higher earner’s personal name lets the loss reduce their salary tax right now.
Debt does not launder through a structure
An investment loan inside a trust is still smart debt — deductible, working for you. Your good debt (the home loan) and your bad debt (credit cards, BNPL, personal loans) do not change character just because a trust exists. Moving debt into a container never turns bad debt into smart debt.
02 The company — a flat-rate parking bay
A company is a separate legal entity that pays tax at a flat rate — 25% for a base-rate entity, or 30% otherwise. Compared with the top personal rate of 47% (including the Medicare levy), that flat rate can look attractive. For this reason, business owners often use a company to hold and retain profits they are not ready to draw personally.
Think of it as a parking bay. Profit sits inside the company, taxed at the flat rate, until it is paid out as a dividend later. Historically, a company was often paired with a family trust as a “bucket” — the trust distributed surplus income into the company to cap the tax rate. However, that particular play is exactly what the announced trust reforms take aim at.
Why the bucket company era is closing
Under the announced measure, a corporate beneficiary would receive no credit for the trustee’s 30% minimum tax. Consequently, the trust pays 30%, and then the company pays its own tax on the same income again. Treasury’s consultation paper illustrates an effective rate of roughly 42.9% for a company on the 30% rate. In short, cycling trust income into a bucket company would no longer cap anything — it would double up.
That does not make companies useless. On the contrary, it makes the company more attractive in its own right. Increasingly, business owners may hold the operating business directly in a company, keeping the flat rate and franking, rather than routing profit through a trust first. Additionally, the Government has flagged a three-year rollover window from 1 July 2027 to 30 June 2030 to help groups restructure out of discretionary trusts without triggering the usual tax consequences.
Remember, though, that this measure is still only announced. Therefore, the sensible move now is to model the impact and understand your options — not to rip up a working structure before the legislation exists.
Where a company does not belong
Crucially, a company is the wrong place for the family home. The main residence capital gains tax exemption applies to homes held personally, not to homes held inside a company. Put simply, holding your home in a company can quietly hand a future tax bill to a property that would otherwise have been CGT-free. In short, companies are for business profit and certain investments — not for the roof over your head.
03 The SMSF — control, and who it actually suits
Here is where most explanations go wrong. Superannuation itself is not really a structural choice — if you earn a wage in Australia, you already have it. Earnings are taxed at just 15% in accumulation, and at 0% in the retirement phase. Consequently, the real decision among family wealth structures is not “super or not.” It is whether to run your own self-managed super fund.
An SMSF is a fund you control as trustee. Crucially, it buys you one thing above all: the ability to own assets a large retail or industry fund simply will not hold for you. However, that control arrives with trustee duties, an annual audit, compliance costs, and real personal responsibility. As a result, an SMSF is a deliberate structure — not a default, and definitely not for everyone.
Who an SMSF genuinely suits
In practice, an SMSF earns its keep for three groups. Each one has a job that an ordinary fund cannot do.
The three groups an SMSF is really built for
1. Business owners. An SMSF can hold business real property — most commonly the premises the business trades from. The business then pays commercial rent to the fund, moving money from the operating entity into a 15%-taxed environment you control.
2. Investors with access to tailored or private assets. Direct holdings, unlisted or private investments, and bespoke opportunities that a pooled retail fund will never offer on its menu.
3. Larger balances wanting to gear into commercial property. With enough in the fund, borrowing to acquire commercial property becomes viable — and that borrowing is smart debt, working inside the fund.
Notice what connects those three. In each case, the SMSF exists because the asset could not be held any other way. That is the test. Conversely, if your plan is a straightforward portfolio of index funds and ETFs, a low-cost industry or retail fund will very likely do that job more cheaply — and without you signing up as a trustee.
Why the residential gearing case has narrowed
Gearing inside super used to lean heavily towards residential property. Increasingly, though, the case has shifted. Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, negative gearing restrictions on established residential property take effect from 1 July 2027, with grandfathering for holdings in place before 12 May 2026. Importantly, the new-build exemption available elsewhere does not extend to an SMSF. Furthermore, gearing benefits are muted inside a fund that is already taxed at only 15%.
For this reason, commercial property — and business real property in particular — is now where the strongest SMSF gearing case usually sits. Above all, the asset should justify the structure, not the other way around.
What changed: the new $3 million super rules
One more current change matters here. From 1 July 2026, the Division 296 tax is now law. In effect, it adds an extra 15% tax on earnings attributed to the portion of an individual’s total super balance above $3 million, with a further tier above $10 million. Notably, it applies per person — so a couple can hold roughly $6 million across two balances before the higher tier bites.
For most families, this changes little. That said, it does mean super is no longer a bottomless tax shelter at the very top. Therefore, the “just tip everything into super” reflex now deserves a second look for high-balance households. We break down the detail in what the new $3 million super tax means for you, and in our guide to starting an SMSF.
Which structure tends to suit whom
Protecting assets from business or professional risk → A discretionary family trust. This remains its most durable job.
Retaining business profit → A company — increasingly in its own right, rather than as a “bucket” beneath a trust.
Owning assets a normal fund cannot hold → An SMSF — business premises, private assets, geared commercial property.
A simple long-term retirement portfolio → Ordinary super. No SMSF required.
The family home → Held personally, to keep the CGT exemption.
How family wealth structures work together over time
In practice, these family wealth structures are rarely an either/or choice. A typical journey might start with everything held personally, build super contributions as income grows, introduce a trust where protection genuinely matters, and use a company to hold retained business profit. An SMSF, meanwhile, tends to arrive last — and only when there is a specific asset that requires it. Each layer is added when there is a genuine job for it, not before. Given the proposed trust reforms, that discipline matters more than ever.
This layering also carries into the next generation. Structures shape not only how wealth is taxed today, but how cleanly it passes on tomorrow. Indeed, Adviser Ratings’ 2025 industry research found tax minimisation is the single biggest concern Australians raise about transferring wealth to family. If you are also thinking about teaching the next generation, our children’s series Bunnies & Monies starts those money conversations early.
The plain-English summary
What to do next
Before you build anything, write down the job first. Are you protecting assets, splitting income, parking profit, or investing for retirement? Once the purpose is clear, the right container usually becomes obvious. Conversely, choosing a structure first and hunting for a reason afterwards is how families end up with expensive containers that hold nothing useful.
