Choosing the Right Structure for Family Wealth

Choosing the right structure starts with a question most people skip: what is this actually for? Get that wrong, and you can spend thousands building a container that quietly works against you.

Here is a scene that plays out constantly. A friend mentions their accountant set up a family trust, and it “saved them a fortune.” So you assume you need one too. However, their goals, their income mix, and their assets may look nothing like yours. Structures copied from someone else are one of the most common — and most expensive — mistakes we see.

This article is about choosing the right structure on purpose, driven by your goals rather than by what worked for your neighbour. We will walk through the mistakes that happen when structures are chosen for the wrong reasons, and then set out the sequence that actually works. Ultimately, the best structure is the one that matches the job you genuinely need done.

With that map in mind, let us look at where families go wrong. Each mistake below comes from the same root cause: the structure was chosen before the purpose was clear.

This is the big one. Your friend’s trust may be perfect for their situation — a business, several investment properties, and adult children on low incomes to receive distributions. Meanwhile, you might be a PAYG couple with one property and no one to split income to. In that case, the same trust adds cost and complexity while delivering almost nothing.

The lesson is simple. A structure that saved someone else money can quietly cost you money. Therefore, the right starting point is your goals, not the setup that happened to suit a household with a completely different shape.

Negative gearing can be a legitimate and powerful lever during your accumulation years — roughly the 10 to 20 before retirement — provided you have a genuine emergency fund and savings buffer behind it. The deduction is a real return in its own right. However, the structure you hold the property in decides whether you actually capture that return.

Here is the trap. A trust cannot pass its losses out to you, so a negatively geared property inside a trust has its loss trapped until the trust earns income. By contrast, holding it in the higher-earning partner’s name lets that loss reduce their salary tax straight away. As a default, the higher-tax-paying partner’s name is the usual starting point — though CGT on exit, retirement income splitting, and asset protection can all create exceptions worth weighing.

On the debt itself, keep the labels straight. An investment loan is smart debt — deductible and working for you. The home loan is good debt. Credit cards, BNPL, and personal loans are bad debt. No structure converts bad debt into smart debt; it never has.

Occasionally someone hears that companies pay a lower flat tax rate and decides to hold the home there. Unfortunately, this can be an expensive error. The main residence CGT exemption applies to homes held personally, not to homes held inside a company. As a result, a home that would have been completely capital-gains-tax-free can become fully taxable on sale.

Put simply, a lower headline tax rate means nothing if the structure strips away a valuable exemption elsewhere. This is exactly why choosing the right structure has to weigh the whole picture, not one attractive number in isolation.

Structures cost money to set up and money to run every year. Consequently, building one before you have meaningful assets to place inside it is pure cost drag. The clearest example is an SMSF opened without a job for it. In that case, the annual compliance, accounting, and audit fees can quietly outweigh any benefit for years.

Remember what an SMSF is actually for. It suits business owners holding their business premises, investors with access to tailored or private assets, and larger balances gearing into commercial property. By contrast, if you simply want a diversified portfolio of index funds, an ordinary low-cost super fund does that job — usually more cheaply, and without trustee duties. In short, an SMSF should follow a specific asset, not ambition.

The same discipline applies to every container. First build the asset base and clarify the goal. Then add the structure when there is a genuine job for it. Structures should follow your wealth, not run ahead of it.

Tax is important, yet it is only one factor. When a structure is chosen for tax alone, families often overlook CGT on exit, succession and estate planning, asset protection, and simple control over who decides what. These non-tax factors frequently outlast the tax saving that motivated the whole exercise.

Succession deserves special attention. Adviser Ratings’ 2025 research found tax minimisation and preserving family wealth across generations rank among the top concerns Australians raise about passing on wealth — yet structures are often built without any succession plan attached. In short, the structure that saves the most tax this year is not automatically the one that hands wealth cleanly to your children.

This one is live right now. In the 2026–27 Federal Budget, the Government announced a 30% minimum tax on discretionary trusts, proposed to begin on 1 July 2028. The trustee would pay at least 30% on the trust’s taxable income. Beneficiaries other than companies would receive a non-refundable credit for that tax.

Two consequences follow, and both hit the reasons people usually build trusts. First, splitting income to a low-rate beneficiary stops working, because the credit cannot be refunded below 30%. Second, and more starkly, a corporate beneficiary would get no credit at all — so the trust pays 30%, and the bucket company then pays tax on the same income again. Treasury’s consultation paper illustrates an effective rate around 42.9% for a company on the 30% rate.

Put simply, the bucket company era is closing. Therefore, setting up a trust today primarily to split income or feed a bucket company means building for a rule that is already being dismantled.

Above all, notice what this vindicates. A trust built for asset protection still does its job. A trust built purely for a tax outcome is now exposed. That is precisely the argument this article has been making from the start.

Choosing the right structure: the sequence that works

Choosing the right structure follows a simple order once you strip out the noise. First, name the goal in plain words — protect, split, park, or grow. Second, map your real situation: incomes, assets, business risk, and time horizon. Third, only then select the container that fits, and add it when it earns its keep.

This is also why generic advice struggles. Two households on the same $280,000 combined income can need completely different structures, because their goals and risks differ. Accordingly, the answer is rarely found in a forum thread — it is found by starting from your own situation.

What to do next

If you are weighing up a structure, resist the urge to start with the container. Instead, start with the goal, then test whether the structure genuinely serves it across tax, protection, control, and succession. When those four line up, you have found the right fit. If they do not, the sophisticated structure is just expensive.
