Are Discretionary Trusts Still Worth It for ASX Investors In A World Of Minimum 30% Distribution Taxes?

For decades, discretionary trusts have been one of the most popular investment structures for higher‑income Australians. They offered tax flexibility, asset protection and estate‑planning advantages in a way that direct ownership simply could not match. The ability to stream income to low‑tax family members, apply the 50% CGT discount at the trust level and manage distributions year by year made trusts a natural fit for ASX investors building long‑term wealth.

The proposed Federal Budget changes, however, have forced many investors to reassess that long‑held assumption. A minimum 30% tax on trust distributions, if implemented broadly as outlined, would materially alter the economics of using a discretionary trust for passive share portfolios. The question now is whether trusts remain appealing for ASX investors or whether the landscape has shifted enough to justify a different approach.

Why did discretionary trusts become so popular in the first place?

A discretionary trust is a simple concept with powerful implications. A trustee controls the assets. Beneficiaries receive distributions. The trust deed governs how income can be allocated. The trust itself generally does not pay tax if income is distributed. Instead, beneficiaries are taxed at their own marginal rates. That flexibility is the core of the structure.

For ASX investors, the benefits were clear. A family could direct franked dividends to a retired parent on a low tax rate. Capital gains could be distributed to adult children. Income could be smoothed between family members depending on circumstances each year. The trust could apply the 50% CGT discount on assets held for more than 12 months before distributing the gain. That made trusts particularly powerful for long‑term equity portfolios where capital appreciation was a major component of returns.

There were also non‑tax reasons for using trusts. Asset protection is a major one. A properly structured discretionary trust can provide separation between personal liabilities and investment assets, which appeals to business owners, professionals, directors and higher‑net‑worth families. Estate planning is another. Trusts allow intergenerational wealth transfer with more flexibility than direct ownership. Families can transfer control of the trust structure over time without triggering the same tax and legal consequences associated with transferring assets directly.

These advantages made discretionary trusts the default structure for many investors. The trade‑offs were manageable. Trusts involve annual accounting costs, tax returns, legal setup fees, trustee obligations and administrative complexity. They also cannot distribute tax losses, which means losses remain trapped until future profits emerge. Banks may treat trust borrowing differently, making leverage more complex. Even so, the benefits often outweighed the drawbacks.

Why Labor’s proposed changes are a big deal for trusts

The proposed minimum 30% tax floor on trust distributions strikes at the heart of the traditional tax planning rationale. Historically, one of the biggest advantages of trusts was distributing investment income to non‑working spouses, university‑age adult children, retirees or beneficiaries with low taxable income. If distributions face a minimum 30% tax regardless of the recipient’s marginal rate, a large part of that flexibility disappears.

This is particularly relevant for ASX investors who rely on franked dividends, ETF distributions or realised capital gains. A trust that once allowed income to be streamed to a low‑tax beneficiary may now face a flat 30% tax outcome. That is materially different from the current environment where a retiree or low‑income adult child might pay little or no tax on the same distribution.

The impact is even more pronounced for high‑yield portfolios. Investors who built trust structures around franked dividend streams may find that the after‑tax advantage narrows significantly. The same applies to investors who relied on distributing capital gains to beneficiaries with lower marginal rates. The proposed changes reduce the effectiveness of those strategies.

Does this mean trusts are no longer useful?

Not necessarily. The appeal of trusts under this regime will be narrow, but won’t entirely disappear. The key is understanding what trusts are good at and what they are not. Trusts may become less appealing for pure passive ASX investing where the primary objective is tax minimisation. Smaller portfolios may no longer justify the administrative burden. Investors who used trusts mainly for income splitting may find that the economics no longer stack up.

However, trusts remain highly attractive in certain other situations. For high‑income professionals and business owners, asset protection remains a critical consideration. The ability to separate personal risk from investment assets is not affected by the proposed tax changes. Estate planning benefits also remain intact. Families with substantial private business income, large property portfolios or intergenerational wealth objectives may still find trusts extremely useful structurally.

There is also a scenario where trusts become relatively more attractive for growth‑oriented investing than for income investing. If investors focus on long‑duration capital growth and defer realisations for many years, the impact of annual distribution taxation becomes less severe. A trust that holds growth assets for decades and realises gains infrequently may still deliver strong after‑tax outcomes, particularly if the CGT discount remains available at the trust level.

What alternatives might become more appealing than trusts?

Even so, if the proposed changes proceed, investors may increasingly consider other structures.

Superannuation is the most obvious. If personal investing becomes less tax efficient, super’s 15% accumulation tax rate and 0% pension phase treatment become far more attractive. Yes, you read that right, you pay just 15% on super as you accumulate but don’t pay any tax when you draw down on your super having reached the eligible age. With this in mind, investors may bring forward concessional contributions, use carry‑forward caps more aggressively and prioritise long‑term investing inside super.

Investment companies may also gain appeal. Companies already pay a flat corporate tax rate, allow profits to be retained and can smooth dividends over time. For investors who want to reinvest earnings without triggering personal tax each year, a company structure may offer advantages. The trade‑off is that eventual dividends are taxed at the shareholder level, but for some investors the ability to control timing is valuable.

Direct ownership may also become more attractive for smaller portfolios. If the administrative burden of a trust no longer justifies the benefit, many investors may simply choose to hold ASX shares personally. This is particularly true for investors who do not require asset protection or complex estate planning.

The broader context matters more than just one change

Tax law rarely operates in isolation. Investors need to consider Division 7A rules, unpaid present entitlements, bucket companies, land tax, state duties and super contribution strategies in conjunction with trusts. A change in one area can affect the economics of another. The proposed trust reforms may interact with other parts of the tax system in ways that are not yet fully understood.

The likely outcome is not the death of the family trust. Instead, trusts may shift from being a broadly popular retail investing vehicle toward something used mainly where asset protection matters, succession planning matters or portfolio scale justifies the complexity. For many ordinary ASX investors, the old equation was simple: why invest personally if a trust gives more flexibility? The proposed changes complicate that answer considerably.

The bottom line

Discretionary trusts have been a cornerstone of wealth management for Australian investors for decades. The proposed minimum 30% tax on trust distributions changes the landscape, but it does not eliminate the value of trusts. It simply narrows their appeal. For investors who used trusts primarily for income splitting, the economics may no longer justify the structure. For investors who value asset protection, estate planning and long‑term control, trusts remain compelling.

The challenge now is to reassess the purpose of the structure rather than assuming it remains the default. Trusts are still powerful tools even if not as much as before, but they need to be used for the right reasons and Labor’s changes mean that what were the right reasons prior to them may not be the right reasons now.
