Most common questions on 2026 tax changes, Answered
Australia’s most significant tax overhaul since 1999 arrives with a hard deadline, a transitional trap most buyers have not spotted, and a CGT change that hits shares just as hard as property.
On the evening of 12 May 2026, Treasurer Jim Chalmers delivered what he called the most ambitious tax reform in 26 years. The headlines focused on negative gearing. The bigger change, in some ways, is the one that barely made the front pages: the removal of the 50% capital gains tax discount across almost every asset class Australians hold.
For anyone buying property, holding an investment portfolio, or wondering whether to sell before the rules change, the next thirteen months will involve decisions with long financial tails. The confusion, in many cases, is greater than the actual risk, but some of the traps are real, and a few are being badly misread.
What follows are the twelve questions buyers and investors are actually asking, answered as precisely as the announced rules allow.
1. I exchanged contracts before Budget night but settle later. Am I protected under the old negative gearing rules?
Almost certainly yes, and this distinction matters enormously for anyone mid-purchase.
The government’s announcement is explicit on the trigger: the relevant date is contract date, not settlement date. Properties acquired under contracts signed before 7:30 p.m. AEST on 12 May 2026 remain under existing arrangements, even if settlement occurs weeks or months later.
The practical reassurance: if you had exchanged before the deadline, you are not pushed into the new rules simply because the keys haven’t changed hands. Your solicitor should confirm the precise contract timestamp if there is any ambiguity, and you should keep that documentation.
The caveat: the final legislation has not yet been passed. Announced policy and enacted law are not the same thing, and edge cases (split contracts, option agreements, off-the-plan variations) may be treated differently in the drafting. If your situation is complex, don’t rely on the announcement alone.

2. If I buy an established investment property after Budget night but before 1 July 2027, what happens?
This is the most consequential misunderstanding circulating among buyers right now, and getting it wrong is expensive.
Established residential properties purchased after 7:30 p.m. on 12 May 2026 are caught by the new negative gearing restriction. Full stop. The 1 July 2027 date is not a grace period that locks in the old rules permanently. It is simply when the restriction begins to bite.
Here is how it actually plays out:
- Until 30 June 2027: You can still offset rental losses against your wage income under the transitional arrangements. You get a temporary window.
- From 1 July 2027 onward: Losses from that same property can only be offset against other residential property income or capital gains from residential property, not wages. Unused losses carry forward to future years; they don’t disappear. But the annual tax relief against your salary does.
The trap is the assumption that buying now means permanent protection. It does not. Anyone who purchases an established investment property between Budget night and 30 June 2027 should model their cash flow after the transition, not during it.
3. If I already own an investment property, am I grandfathered forever?
For as long as you hold it, yes, under the announced design.
Properties purchased before the Budget night deadline remain fully subject to the existing rules until they are sold. Existing negatively geared landlords face no immediate change to their tax treatment on their current portfolios.
Two important qualifications:
First, “forever” applies to the holding, not the owner. If you sell and reinvest in another established residential property, the new rules apply to that next purchase. Grandfathering does not transfer.
Second, the rules as announced protect existing properties while held. A future government could revisit this. No budget announcement carries a constitutional guarantee. That said, retrospective changes to existing holdings would be politically extraordinary, and there is no current indication of any such intent.
The practical position: if you own a negatively geared established property and are not planning to sell, nothing changes for you in the near term.
4. How does the new CGT system actually work?
There are two moving parts, and most of the public commentary is only explaining one of them.
Part one: indexation replaces the 50% discount. From 1 July 2027, rather than halving your nominal capital gain, your cost base (purchase price plus eligible costs) is adjusted upward for inflation. Only the gain above inflation is taxable. This was, in fact, the original design of Australian CGT before the Howard government simplified it with the flat 50% discount in 1999.
Part two: a 30% minimum tax applies to real gains. This element has received far less attention than it deserves. Even after indexation strips out the inflationary component, any remaining real gain is subject to a minimum tax rate of 30%. If your marginal tax rate is already above 30%, your marginal rate applies. If it is below 30%, because your total income is modest in a given year, or because you have historically structured income across a trust, the floor still applies.
This second element significantly changes tax deferral strategies. The historic incentive to time an asset sale for a low-income year is largely neutralised. It also affects trust distributions of capital gains, which accountants and estate planners are still working through.
Two groups are carved out from the minimum tax: income support recipients including Age Pension recipients (who remain taxed at their marginal rate), and investors in new residential builds (who can choose between the old 50% discount regime and the new indexation regime).
Superannuation funds, including SMSFs, retain their existing one-third CGT discount and are not affected by these changes.
A worked example under the new regime:
You purchase an investment property for $700,000. Five years after 1 July 2027, you sell it for $1,000,000. Assume cumulative inflation over that period is 15%.
Indexed cost base: $700,000 × 1.15 = $805,000 Taxable real gain: $1,000,000 − $805,000 = $195,000 Tax at 30% minimum: $58,500
Under the old 50% discount at a 37% marginal rate: Taxable gain: $300,000 × 50% = $150,000 Tax: $55,500
In this example the outcomes are close. The gap widens sharply when asset growth is strong relative to inflation.
5. Does indexation give a better or worse deal than the old 50% discount?

It depends on one ratio: how fast the asset grew relative to inflation.
The 50% discount was indifferent to inflation, it simply halved whatever gain you made. Indexation, by contrast, is entirely about what fraction of your gain was inflationary and what fraction was real.
The rule of thumb: if your asset grew modestly and inflation was high, indexation may be better. If your asset grew strongly and inflation was moderate, the 50% discount was almost certainly more generous.
Australian residential property has historically delivered strong real capital growth, gains well above inflation. For most property investors with long holding periods and significant nominal gains, the old system would have been the better deal. The new system is a net tightening for that cohort.
A comparison with realistic numbers:
Assume inflation averages 3% per annum over a five-year holding period, roughly 16% cumulative. A property rises from $700,000 to $1,200,000, a $500,000 gain.
| Method | Taxable gain | Tax at 37% marginal rate |
|---|---|---|
| Old 50% discount | $250,000 | $92,500 |
| Indexation (16% CPI uplift) | $388,000 | $143,560 |
In this scenario, strong growth, moderate inflation, indexation costs the investor roughly $51,000 more in tax. The 30% minimum floor does not help; at a 37% marginal rate, the marginal rate applies regardless.
6. Do gains I’ve already accrued before 1 July 2027 still get the 50% discount?
Yes, under the transitional rules as announced.
The reform is explicitly prospective. Gains accrued before 1 July 2027 retain the 50% discount. The mechanism: the asset’s value is established at 1 July 2027, either by formal valuation or by an ATO-approved growth formula, and the 50% discount applies to gains up to that value. Only gains accruing after that date fall under the new indexation and minimum tax framework.
This means the panic-selling instinct, rushing to sell before 1 July 2027 to lock in the 50% discount on everything, is largely misplaced. The discount on pre-2027 gains is preserved whether you sell before or after the transition.
The practical action item: for direct property, getting a formal valuation close to 1 July 2027 creates a clean, defensible record of the transition-date value. For listed shares, the market price on the day suffices. Either way, organised records now will simplify the hybrid CGT calculation considerably when you eventually sell.
7. Should I sell shares or property before 1 July 2027 and put the money in my mortgage offset?
Maybe, but only if the after-tax arithmetic actually works. This should not be a reflex decision driven by the headline.
A quick example:
You hold an asset with a $200,000 capital gain. Under the old 50% discount, $100,000 is taxable. At 39% (including Medicare levy), tax is approximately $39,000. Net proceeds go into a mortgage offset account effectively earning 6% per annum, tax-free.
That sounds appealing. But you are also giving up future capital growth, dividend income, franking credits, and the compounding effect of staying invested. Paying a $39,000 tax bill today to avoid a marginally larger one in 2027 is only rational if you were going to sell anyway, or if you genuinely believe the investment’s future return is weak.
The better question: Would I sell this asset if the CGT rules weren’t changing?
If yes, timing matters, and selling before 1 July 2027 captures the full 50% discount on your entire gain.
If no, the tax tail may be wagging the investment dog.
One important correction worth stating plainly: shares are not a shelter from the CGT change. The negative gearing restriction applies only to established residential property, shares retain full loss deductibility against any income. But the removal of the 50% CGT discount and the introduction of the 30% minimum tax applies to all CGT assets: property, shares, managed funds, business interests. There is no CGT advantage in being in equities over property. They face identical treatment from 1 July 2027.
8. Will rents rise because landlords lose negative gearing?
Some landlords will try. That is not the same as rents rising.
Rents are not set by what landlords need to cover their costs. They are set by what tenants can pay and what the competing market offers. A landlord can ask for anything; the local vacancy rate and tenant alternatives determine whether they receive it.
Treasury’s own modelling puts the expected rent impact at less than $2 per week for a household paying median rent, a figure that reflects the limited and uneven transmission between a tax change and market pricing.
The more granular answer: in suburbs with genuinely low vacancy and strong tenant demand, some landlords may have the pricing power to recover higher costs. In suburbs with rising supply or already-stretched tenants, attempted increases will simply not hold. The tax change is real; the ability to pass it through to rents is local and highly variable.

No, not automatically, and not uniformly.
A landlord’s tax position does not set the market rent. The market does. This is one of the most persistent misunderstandings in property investment commentary.
Two further points:
First, the majority of existing landlords are grandfathered on their current properties. Many will not face an immediate tax change on what they already hold. The population of landlords who might be motivated to raise rents as a direct response to this Budget is smaller than reported.
Second, landlords who do exit as a result of the changes (selling rather than holding) reduce rental supply in their suburb. This could, perversely, give remaining landlords in those markets more pricing power. This second-order effect is worth watching over the next two to three years, but it unfolds slowly and unevenly.
10. Will money now move from property into shares?
Some will shift, but shares are not the tax shelter many investors appear to assume.
The negative gearing restriction is property-specific. Shares retain full deductibility of losses against any income, which is a genuine relative advantage for leveraged equity investors. That part of the story is true.
But the CGT discount removal applies equally to shares and property. Any investor selling a significant share portfolio after 1 July 2027 faces the same indexation-plus-30%-minimum framework as a property investor. There is no CGT refuge in equities. The two asset classes are treated identically under the new capital gains regime.
Where money is more likely to flow:
- Mortgage offset accounts: the return is effectively the mortgage rate, tax-free, with no CGT event on exit
- Superannuation: the one-third CGT discount for super funds is unchanged, and concessional contributions remain highly tax-efficient within caps
- New residential builds: full negative gearing retained, plus investor’s choice of old or new CGT regime on sale
- Broadly held trusts, build-to-rent, and government housing programs: all specifically carved out from the negative gearing restriction
- Fully franked dividend shares: the dividend imputation system is unaffected; franking credits remain valuable for eligible investors
The cleaner frame: this is not a simple “sell property, buy ETFs” moment. It is a shift in incentives toward tax-sheltered structures, longer holding periods, new housing construction, and lower-risk compounding returns.
11. Is a knockdown rebuild counted as a new home?
Most likely yes, if it adds dwellings. If it is a straight replacement, the answer requires legislative confirmation.
The government’s policy intent is to redirect investment toward new housing supply. The Budget material explicitly identifies knockdown rebuilds that add dwellings, demolishing one house to construct two townhouses or three apartments, for example, as eligible new builds. These retain full negative gearing and the investor’s choice of CGT regime.
A one-for-one replacement sits in murkier territory. Physically it is a new structure; economically it does not expand the housing stock. How the final legislation draws this line matters, and the current announcement does not provide complete clarity on the one-for-one case.
The investment implication: if you are purchasing a knockdown site specifically to access the new build tax advantages, get legal advice before committing capital. The policy intent clearly favours projects that add dwellings. The one-for-one case needs the legislation to confirm it.
12. Are new builds automatically better investments than established homes?
No. Tax advantages do not fix bad fundamentals.
New builds now receive materially better tax treatment: full negative gearing retained, and investor’s choice of the old 50% CGT discount or the new indexation regime on sale. That is a genuine and significant advantage that will influence investor behaviour.
But tax treatment is not the only variable in a property investment, and in many cases it is not even the most important one.
Established homes in strong locations may still offer better land content relative to improvements, stronger owner-occupier demand that supports resale, lower defect risk, proven rental yield history, and genuine scarcity in suburbs where no meaningful new supply is physically possible.
New builds in weak locations (oversupplied apartment corridors, outer greenfield estates with poor infrastructure, markets where developer incentives mask underlying demand problems) can still underperform a well-chosen established property in a tight inner or middle suburb, even after accounting for the tax differential.
The decision framework: the tax advantage of a new build improves an already viable investment. It does not rescue a marginal one.
Buy on the fundamentals. Use the tax treatment as a tiebreaker, not as the investment thesis.
What this means in practice
The reforms announced on Budget night are significant, but they are not as chaotic as the immediate reaction suggested. Most existing investors are protected on what they already hold. The real changes affect new decisions: what to buy next, when to sell, and how to structure holdings from here.
The honest summary:
Existing property holders: Grandfathered while you hold. No immediate action required, but get a valuation record in place before 1 July 2027.
Mid-contract buyers: Almost certainly protected by contract date. Confirm the precise timestamp with your solicitor and keep documentation.
Post-Budget established property buyers: The transitional window is real but temporary. Model your cash flow after 2027, not during it, the relief ends on 1 July 2027.
New build investors: Now clearly tax-advantaged over established property. Still requires genuine investment due diligence; the tax benefit does not substitute for location and asset quality.
Share investors: Negative gearing rules unchanged, losses still fully deductible against any income. But the CGT discount is gone from 2027, on exactly the same terms as property.
Everyone selling after 1 July 2027: The 30% minimum tax on real gains is the underreported element of this reform. It affects timing decisions, trust structures, and income-splitting strategies that many investors have relied upon for years. This is where an accountant’s advice is worth paying for.
The rules have changed. The principle hasn’t: understand the asset before you rely on the tax treatment.
