Labor’s Radical CGT Changes: Here Are 11 Things That Will Change In ASX Investors’ Strategies to Minimise Tax

Labor’s proposed CGT changes have triggered a wave of speculation about what investing will look like from 1 July 2027. The headline idea is simple enough: replace the current 50% CGT discount with inflation indexation and introduce a minimum 30% tax on real gains. The implications, however, are anything but simple. If enacted broadly as outlined, the reforms would reshape how investors think about holding periods, asset location, portfolio turnover, and the balance between income and growth.

For investors who want to reduce their tax bill rather than react to it, the message is clear. The strategies that worked for the past two decades may not be the strategies that work for the next one, at least if they want to minimise the tax paid on the investments.

11 Things That Will Change In ASX Investors’ Strategies to Minimise Tax Given Labor’s CGT Changes

1. Grandfathering will become one of the most valuable tax features in the system

It appears that gains accrued before 1 July 2027 will retain access to the existing 50% discount. This will mean older portfolios will become significantly more valuable on an after‑tax basis than newly established ones. That creates a behavioural shift. Investors may become reluctant to sell long‑held positions before the transition date. Others may selectively crystallise gains ahead of the change if they believe the future regime will be materially less favourable.

The practical effect is that portfolios with embedded gains become tax assets in their own right. Investors who understand this early will be better placed to manage the transition. Those who ignore it may find themselves paying more tax than necessary simply because they failed to plan around the timing.

2. Income will be more attractive as capital gains lose their edge

The current CGT system rewards high‑growth investing because half the gain is discounted after 12 months. If that discount disappears and is replaced with indexation plus a minimum tax rate, the relative appeal of ultra‑high growth stocks may fall. Investors may shift toward companies that deliver tax‑effective income rather than relying on large terminal gains.

High‑yield industrials, banks, infrastructure, REITs and franked dividend strategies could all benefit from this shift. The logic is straightforward. If capital gains become less tax efficient, income becomes more valuable. Australia’s dividend imputation system already provides one of the strongest tax advantages in global equity markets. A regime that reduces the attractiveness of capital gains only strengthens that advantage.

3. Long holding periods will become more rewarding, not less

One of the ironies of the proposed CGT changes is that indexation could reward very long holding periods during inflationary environments. If inflation averages 3–4% over a decade and nominal equity returns are 8–10%, a meaningful portion of the gain may be sheltered through indexation. Investors who hold for long periods could find themselves paying less tax on a real basis than those who trade frequently.

This dynamic favours buy‑and‑hold investing, compounders, low‑turnover portfolios and passive ETFs. It also reduces the cliff effect created by the current 12‑month discount threshold. Investors may become more focused on after‑tax real returns rather than arbitrary holding periods.

4. Tax‑loss harvesting will be a more powerful tool

If nominal capital gains are taxed more heavily, capital losses become more valuable. Investors may harvest losses more actively, pair gains and losses more deliberately, and maintain “loss banks” for future years. This is particularly relevant after volatile periods in sectors such as technology, lithium or speculative small caps.

Loss harvesting is already a common strategy among sophisticated investors. Under the proposed regime, it becomes essential. The ability to offset real gains with realised losses could materially reduce tax bills over time.
Portfolio turnover needs to be reconsidered

The existing system strongly rewards crossing the 12‑month threshold. The new framework may reduce that incentive. Some investors may trade more tactically because the penalty for short‑term gains is less severe. Others may trade less because the benefit of realising gains is diminished.

The key is to focus on after‑tax real returns. Investors who continue to trade frequently without considering the tax consequences may find themselves giving up a larger share of their returns than they expect.

5. Family members will still matter, but trusts may not

Marginal tax rates will continue to matter even if the CGT discount changes. Lower‑income spouses, adult children and retirees may remain useful recipients of investments. However, the proposed minimum 30% tax on discretionary trust distributions could reduce the effectiveness of traditional family trust strategies.
Investors who rely heavily on trust structures may need to reconsider whether companies or superannuation funds offer better long‑term tax outcomes.

6. Investing using super funds is going to be relatively more attractive

While personal investing will be less tax efficient, the use of super funds will be compelling. The 15% accumulation tax rate and 0% pension phase treatment are already powerful incentives. A regime that taxes capital gains more heavily outside super only strengthens the case for maximising contributions.

Investors may bring forward concessional contributions, use carry‑forward caps more aggressively, and prioritise long‑term investing inside super. The evolving Division 296 rules for large balances will need to be monitored, but for most investors super remains the most tax‑efficient structure available.

7. Low‑turnover vehicles will be appealing

Assets such as ETFs, LICs and internally low‑turnover active funds may become more attractive because they generate fewer taxable events. High‑turnover managers, momentum strategies and frequent traders may find themselves at a structural disadvantage.

Investors who want to reduce their tax bill should pay closer attention to turnover metrics. A fund that outperforms before tax but generates constant taxable gains may underperform after tax.

8. Ditto, debt recycling

If capital gains are taxed more heavily, investors may look for other ways to improve after‑tax outcomes. Debt recycling is one option.

Converting non‑deductible home debt into deductible investment debt can improve cash flow and increase compounding efficiency, particularly for investors focused on franked dividend streams.
This strategy is not suitable for everyone, but for disciplined investors with stable income it can be a powerful tool.

9. Asset location will become more important

Under an environment with the proposed CGT changes, Investors may increasingly separate growth assets inside super and income assets outside super, or vice versa depending on tax brackets and retirement timelines. The “what” you own may become secondary to “where” you own it.

This is a shift toward more sophisticated portfolio construction. Investors who ignore asset location may pay more tax than necessary even if their asset selection is sound.

10. Borrowing against assets instead of selling will be considered

One of the most common strategies among wealthy investors globally is to hold appreciating assets, borrow against them, and avoid crystallising CGT events. If realised gains become more punitive, this approach may become more common in Australia. Margin loans, portfolio lending and private banking facilities can all be used to access liquidity without triggering tax.

This strategy carries risk and is not appropriate for all investors, but it is likely to become more widely discussed if the reforms proceed.

11. Estate planning will be more valuable

Long‑term holders may increasingly focus on intergenerational transfer strategies, testamentary trusts, timing of disposals and succession planning. Tax management may shift from annual optimisation toward multi‑decade planning.

Here’s a controversial take: The proposed reforms do not necessarily punish disciplined long‑term investors. We’re not saying they will not punish investors at all, but it is not necessarily a doom and gloom situation. The irony is that, indexation may offset a substantial portion of nominal gains over time. The bigger pressure point may fall on high‑turnover investors, speculative traders and those relying heavily on discretionary trusts or rapid capital appreciation.

Conclusion

The proposed CGT reforms represent one of the most significant shifts in Australian tax policy in decades. Investors who adapt early will be better positioned to reduce their tax bill and preserve long‑term wealth. Those who continue to rely on strategies designed for the old regime may find themselves paying more tax than necessary.

Clearly whatever it means for you, there is one point that has always mattered but hits home more than ever: tax efficiency is a central part of portfolio construction, not an afterthought.
