If you’ve spent any time reading headlines around the 2026 Budget lately, you’d be forgiven for thinking the 50% capital gains tax (CGT) discount was already halfway to the grave.
Depending on the publication, it’s either:
- Doomed
- Under attack
- Politically unavoidable
- Or apparently disappearing tomorrow
For long-term ETF investors, that kind of coverage can feel unsettling. Especially when so much investing advice in Australia has historically revolved around buying quality assets, holding them for years and benefiting from the CGT discount down the track.
But there’s an important distinction that tends to get lost once tax debates hit the news cycle. People talking about reform is not the same thing as reform actually happening.
Australia has spent decades loudly arguing about policies that never make it into law. Others get diluted beyond recognition somewhere between Treasury, Parliament and the evening news.
So before reshuffling a portfolio based on a few dramatic headlines, it’s worth looking at what’s genuinely changed and what’s still just political conversation.
So… has anything actually changed?
Yes, but not immediately. The current 50% CGT discount still exists today. If you’ve held an ETF, share or investment property for more than 12 months, eligible investors can generally still halve their taxable capital gain.
What changed is that the 2026-27 Federal Budget announced plans to overhaul the system from 1 July 2027.
Here’s the short version:
|
Current CGT rules |
Proposed system |
|
Flat 50% CGT discount |
Inflation-based discount |
|
No minimum CGT rate |
New 30% minimum tax on gains |
|
Same rules across most investments |
Special treatment proposed for new builds |
Under the proposed model, investors would no longer automatically receive a flat 50% discount to reduce CGT. Instead, gains would be adjusted for inflation first.
Imagine you bought an investment for $10,000 and sold it years later for $18,000. Right now, the gain is simply treated as $8,000.
Under the proposed model, inflation over that period could increase your cost base before tax is calculated. If inflation adjusted the original purchase price to $12,000, your taxable gain would fall to $6,000 instead.
In other words, the government says it wants to tax the “real” gain rather than applying the same discount percentage to everyone.
One detail that hasn’t received as much attention is the proposed transition arrangement for existing assets.
Under the Budget announcement, investments bought before 1 July 2027 wouldn’t simply move wholesale into the new system. Instead, gains accrued before that date would effectively remain under the current rules, while gains accrued after that point would fall under the new inflation-based model.
In practice, that could mean investors need a valuation for assets held on 1 July 2027 so future gains can effectively be split across the two systems.
That’s important because it means long-term investors won’t necessarily lose access to the existing CGT discount on gains already built up before the proposed changes begin.
It’s also worth mentioning that these are still proposed reforms. A Budget announcement isn’t the same thing as legislation passing Parliament. And Australia has a habit of turning “definite” tax changes into years of political trench warfare.
So while investors are right to pay attention, they’re still reacting to a proposal, not a finalised tax system.
What the CGT discount actually is
The CGT discount is one of those things many Australians use without fully understanding.
In simple terms, capital gains tax can apply when you sell an investment for more than you paid for it.
Let’s say you buy ETF units for $10,000 and later sell them for $15,000. Your capital gain is $5,000. Under current rules, if you’ve held that investment for more than 12 months, eligible investors can generally reduce that gain by 50%. So instead of paying tax on the full $5,000 gain, you’d generally only pay tax on $2,500.
Importantly, that doesn’t mean the gain is “taxed at 50%”. It means only half the gain gets added to your taxable income. It’s a distinction people mix up constantly.
The discount has been around since 1999, when Australia moved away from indexing capital gains for inflation. Since then, it’s become deeply embedded in the way Australians think about long-term investing, whether that’s ETFs, property or broader wealth-building strategies. That’s why any discussion around changing it tends to generate strong reactions.
The 12-month holding rule matters more than people realise
One of the stranger quirks of the CGT system is how dramatically timing can affect the outcome.
An investor who sells after 11 months and 29 days generally receives no CGT discount. But an investor who waits another few days may suddenly cut their taxable gain in half. Same investment, same gain, completely different tax treatment.
That’s one reason long-term investing strategies often emphasise patience and low turnover. Constantly buying and selling doesn’t just increase stress, but it can also create less favourable tax outcomes.
And ironically, investors trying to aggressively optimise around market news or political headlines can sometimes generate extra tax events they didn’t need in the first place.
ETF investors can trigger tax without selling anything
A lot of newer investors assume tax only matters once they sell their ETFs. Unfortunately, though, the ATO is a little more proactive than that.
ETF investors can generally encounter tax in two main ways:
- Distributions received while holding the ETF
- Capital gains triggered when selling units
That first point catches people off guard surprisingly often. Even if you never touch your portfolio, your ETF can still distribute taxable income during the holding period through things like dividends, foreign income and capital gains.
Then there’s CGT when selling – that’s where the discount becomes particularly relevant.
Unrealised gains vs realised gains
This is where a lot of investing conversations become unnecessarily confusing.
Not every portfolio increase creates an immediate tax bill. If your ETF rises from $5,000 to $7,000 but you haven’t sold it, that gain is generally unrealised. In other words, it only exists on paper. The investment could keep rising, but it could also fall next week. Nothing has actually been locked in yet.
Once you actually sell the investment, the gain generally becomes realised, and that’s usually when CGT becomes relevant.
For long-term ETF investors, this distinction matters enormously. Someone building wealth steadily over decades may see substantial portfolio growth without triggering major CGT events simply because they aren’t constantly selling. A paper gain isn’t the same thing as cash in the bank.
Why governments keep revisiting the CGT discount
The CGT discount gets debated constantly because it touches everything from housing affordability and wealth inequality to government revenue.
Critics argue it disproportionately benefits wealthier Australians and encourages speculative investing. Supporters argue it rewards long-term investment and compensates for inflation.
Like most tax debates, the reality is more complicated than either side usually admits on television panels. And importantly for investors: even if governments decide they want reform, there are countless ways they could structure it.
In this case, the government has already outlined the broad direction it wants to take. But there’s still a meaningful gap between a Budget announcement and a fully legislated tax system. The final version could still change significantly once legislation is drafted, debated and negotiated.
That’s why the current conversation feels slightly chaotic. Some people are discussing the announced policy direction, while others are reacting as though the final rules already exist.
What the proposed changes could actually mean in practice
The proposed reforms don’t necessarily mean investors suddenly pay dramatically more tax across the board. In some situations, investors with long holding periods during high-inflation environments could potentially end up with a smaller taxable gain under the inflation-based model.
But the outcome would still depend on various factors. These include how long the asset was held, how much inflation occurred during that period, the size of the gain and what the final legislation ultimately looks like.
Here’s a simplified hypothetical example.
Imagine Priya buys ETF units for $20,000 and eventually sells them for $40,000. Under the current system:
- Capital gain = $20,000
- 50% discount applied
- Taxable gain = $10,000
Now imagine the same investment under the proposed inflation-based system. If inflation over that period adjusted Priya’s original cost base from $20,000 to $28,000, the taxable gain would instead fall to $12,000. That’s higher than under the current discount model, but still lower than taxing the full $20,000 gain.
Importantly, though, under the proposed transition rules, gains accrued before 1 July 2027 would generally still fall under the existing CGT framework rather than the new inflation-based system.
For some investors, particularly those with large gains accumulated during lower-inflation periods after that date, the new system could potentially lead to more tax being paid than under the current rules. For others, the difference may be smaller than the headlines suggest.
The proposed 30% minimum tax on gains is also a significant shift.
The final mechanics still aren’t entirely clear because detailed legislation hasn’t been released yet. But broadly speaking, the proposal appears designed to stop investors from waiting for a particularly low-income year – like a career break, early retirement or a temporary drop in income – to realise large capital gains at very low tax rates.
Instead, the government appears to want investors with substantial gains to still pay a baseline level of tax, even after inflation adjustments are factored in.
For investors building substantial portfolios outside super, that could reduce some of the tax advantages currently associated with long-term capital growth. And over multi-decade investing horizons, relatively small tax differences can compound into meaningful changes in after-tax returns.
Superannuation complicates the picture further
The conversation also becomes more nuanced once super enters the equation.
Currently, complying super funds generally receive a one-third CGT discount on eligible assets held longer than 12 months rather than the 50% discount available to many individuals.
But super is also taxed concessionally overall, which can make it highly tax-effective for long-term investing despite the smaller discount. That’s why many Australians build wealth across multiple structures – personal investing, super and sometimes trusts – depending on their goals and tax circumstances.
All of that is a reminder that simplistic “this tax rule changes everything” commentary tends to miss the bigger picture. Most serious long-term investors are making decisions across decades, not reacting to a single policy headline in isolation.
What this means for ETF investors
Generally speaking, long-term ETF investors are investing for goals that may still be decades away, like retirement, financial independence, family security, flexibility or maybe even helping future generations. And over those kinds of timeframes, consistency usually matters far more than short-term market noise.
That doesn’t mean tax policy is irrelevant. Understanding CGT still shapes the way investors think about holding periods, portfolio turnover, rebalancing and where assets are held.
But there’s also a point where reacting to every speculative headline becomes counterproductive.
Investing already gives people plenty to worry about. Elections, recessions, inflation, interest rates, market crashes… the list never really ends. That’s partly why long-term investing philosophies like ours at Pearler tend to focus so heavily on automation, diversification and consistency rather than constantly repositioning around short-term uncertainty.
Tax rules will keep shifting, and the headlines probably won’t calm down anytime soon. But for many investors, the harder challenge is staying disciplined long enough to let compounding actually do its job.
