What the 2026 Federal Budget changed for property investors

The Federal Budget handed down on 13 May 2026 introduced three structural changes to property investment tax treatment:

1. Negative gearing restricted to new builds

Investors who acquire established residential property after budget night can no longer offset rental losses against their salary income. Interest deductibility remains fully intact for new builds, signalling a clear policy intent: tax breaks for investors who add to housing supply, not for those competing with first-home buyers for existing stock.

2. CGT discount replaced with indexation

The flat 50% discount on capital gains for assets held longer than 12 months — in place since 1999 — has been replaced with the pre-1999 indexation model. Investors are now taxed on the real (inflation-adjusted) gain rather than receiving a fixed concession.

3. Grandfathering for existing assets

Both changes apply only to assets acquired after budget night — 13 May 2026. Properties purchased before that date continue under the old rules. The Commonwealth Bank’s economics team estimated the grandfathering provision substantially reduces the near-term revenue impact, meaning existing investors are politically and practically protected.

What the 2026 Budget did NOT change

This is where most of the reaction misses the mark. Your existing portfolio is not affected. If you own established investment property acquired before budget night, you can continue to claim negative gearing under the existing rules and access the 50% CGT discount. Property investment is not dead. The structural drivers — population growth, supply undersupply across Sydney, Brisbane, Perth, and Hobart, rental yield compression, and capital growth fundamentals — do not change because of a tax treatment shift. The math changes. The opportunity does not disappear. New builds remain fully advantaged. Interest deductibility, depreciation schedules, and CGT treatment for new builds all continue. For investors with the right strategy, this opens a clean pathway. Established property still works in many scenarios. A neutrally or positively geared established property in a strong capital growth market is not affected by the loss of negative gearing — because there is no loss to deduct. This is the kind of acquisition strategy serious investors should already be running.

What this means for property investors: three scenarios

If you already own investment property (acquired before 13 May 2026)

You are grandfathered. Do nothing reactive. The most expensive mistake would be panic-selling a grandfathered asset that is still performing — and then trying to re-enter the market under the new rules. Hold your strategy. Any new acquisition decision should stand on its own merits.

If you are buying established property under the new rules

The question is no longer whether you can offset the loss — it is whether the asset performs without the negative gearing assumption. Many established properties in strong growth markets do. The strategy shifts from cash flow tax offset to capital growth fundamentals. Strong yields, undervalued growth markets, and neutral-or-better cash flow at purchase become the new baseline.

If you are starting to invest post-budget

The decision logic has changed but not the answer. New builds become structurally more attractive for tax-driven investors. Established stock requires sharper acquisition criteria. The bar goes up. So do the returns for investors who clear it.

Understanding the CGT changes 2026 Australia

The shift from a flat 50% discount to indexation is the bigger structural change long-term — and it received less attention than it deserved. Under the previous 50% rule, an investor who buys for $800,000 and sells for $1.2M after five years pays tax on $200,000 (50% of the $400K gain), regardless of inflation. Under indexation, the cost base is adjusted for inflation. If inflation runs at an average of 3.5% over those five years, the indexed cost base is approximately $950,000, and the taxable gain is $250,000 — taxed at the full marginal rate. For long-held assets in moderate-inflation environments, indexation can be roughly comparable to the 50% discount, depending on the holding period and inflation trajectory. For shorter-held, speculative gains, indexation removes the free ride. That is a deliberate policy outcome. The Parliamentary Budget Office previously indicated that the shift to indexation may produce only a modest revenue uplift — because in a low-to-moderate inflation environment, the two regimes converge. Investors holding quality assets for the long term are not the target of this change. Short-term speculators are.

APRA lending rules in 2026: the constraint investors overlook

While negative gearing dominates the headlines, a significant constraint for many investors is APRA’s macroprudential cap introduced in 2026. Banks are restricted to no more than 20% of new mortgages going to borrowers with a debt-to-income (DTI) ratio of six or more. High-leverage investors building portfolios on stretched serviceability will find borrowing capacity tightened well before tax changes hit their cash flow. If you have an existing pre-approval, confirm it remains valid. If you are building a portfolio, debt structure and serviceability planning matter more in the post-2026 environment than they have in a decade.

Property investment strategy in 2026: what to actually do

Review your acquisition criteria

Reassess your portfolio strategy against the new tax architecture — particularly the established vs. new build split, the CGT indexation impact on planned hold periods, and the DTI ceiling against your serviceability. A data-driven research and strategy process is essential to identify assets that perform without the negative gearing offset.

Understand your deductibility position

Many investors are unsure which costs remain deductible under the new rules. For a detailed breakdown, see our guide on whether buyers agent fees are tax deductible.

Build a written investment strategy

If you do not have a written, data-led investment strategy, the post-2026-budget environment is the moment to build one. Our podcast, Invest Smarter, Grow Faster, covers the strategic frameworks that work across market cycles.

Why a buyers agent in Sydney matters more now, not less

A common reflex when tax incentives change is to assume the case for professional buying support weakens. The opposite is true. Previously, a marginal property purchase could be rescued by negative gearing. Tax offset covered a multitude of acquisition mistakes. Under the new rules, the asset has to perform on its own fundamentals — market selection, growth thesis, yield, structure. The cost of buying the wrong property has gone up. The cost of buying the right one is exactly what it was. At Search Party Property, we run a data-led acquisition process across NSW, QLD, WA, TAS, and the ACT. Our clients outperform the median market by 200%, not because of tax structuring, but because of underlying asset selection. That model becomes more valuable, not less, in the post-budget environment.

Frequently asked questions: negative gearing changes 2026

Will my existing investment property be affected by the negative gearing changes?

No. Grandfathering provisions apply to properties acquired before budget night (13 May 2026). Your existing portfolio continues under the previous rules — you can still claim negative gearing and access the 50% CGT discount on those assets.

Is property investment still worth it after the 2026 budget changes?

Yes — but the strategy changes. New builds become structurally more tax-advantaged. Established property requires sharper acquisition criteria, with capital growth and neutral-or-better cash flow at purchase becoming the new baseline. The fundamentals of property as a wealth-building vehicle remain intact.

What are the CGT changes 2026 Australia — should I sell existing assets?

Existing assets acquired before budget night are grandfathered under the current 50% discount. There is no immediate tax-driven case to sell existing holdings. Indexation applies only to assets acquired after 13 May 2026.

Should I invest in new builds instead of established property?

For tax-driven investors, new builds are more attractive under the 2026 rules. For pure capital growth investors, the answer depends on the specific asset and market. New builds rarely outperform established stock on capital growth — but the tax treatment now offsets some of that gap. A data-driven assessment of the specific asset is essential.

How will the 2026 Federal Budget affect property prices?

Most economists, including the CBA Economics team, expected modest downward pressure on investor demand in the short term, partially offset by stronger new build incentives. Grandfathering dampens the immediate price impact. Sydney prices are not expected to fall materially based on this policy alone, given the structural undersupply in key markets.

When did the negative gearing policy changes take effect?

The policy applies to properties acquired after 13 May 2026 (budget night). Grandfathering applies to all properties purchased on or before that date. Always confirm the current legislative position with a qualified tax adviser, as final legislation may include transitional provisions.

Are buyers agent fees still tax deductible under the new rules?

The deductibility of buyers agent fees is a separate question from negative gearing. See our detailed guide: Are buyers agent fees tax deductible?
