14 May What the 2026 Budget Means for Sydney Property Buyers

The federal budget delivered Tuesday night contains the most significant changes to property investment rules in a generation. If you own property, rent, or are planning to buy, here is what you need to know.

The Two Key Changes 

1. Negative Gearing — from 1 July 2027 

Negative gearing allows investors to offset a rental loss against other income, such as their salary. From 1 July 2027, this will only apply to new builds. 

Here is how it breaks down depending on when you bought: 

• Own a property now? You are fully protected. You can continue to negatively gear it indefinitely — until you sell. 

• Buying between now and 30 June 2027? You can negatively gear during that window, but from 1 July 2027, no further offset against income applies. 

• Buying after 1 July 2027? Negative gearing is only available if you purchase a new build (vacant land construction or a development that adds to housing supply — a knock-down rebuild of a single home does not qualify). 

• What happens to losses? They are not lost. They can be carried forward and offset against future rental income or capital gains when you eventually sell. 

Commercial property and shares are unaffected by these changes. 

2. Capital Gains Tax — from 1 July 2027 

The 50% CGT discount — which halved the taxable gain on assets held for more than 12 months — is being replaced from 1 July 2027 with two new mechanisms: 

1. Cost base indexation: Your cost base is adjusted for inflation, so only real gains above CPI are taxed — not the portion that simply kept pace with rising prices. 

2. 30% minimum tax on capital gains: Regardless of your marginal tax rate, capital gains will be taxed at a minimum of 30%. 

What about property you already own? 

Gains accrued before 1 July 2027 still receive the existing 50% discount. Only gains accruing after that date fall under the new rules. This means property owners will need a formal valuation as at 1 July 2027 — that valuation becomes the new cost base, and the indexation method applies to any growth from that point forward. 

New build investors  get a choice when they eventually sell: the 50% discount or the new indexation and minimum tax regime, whichever is more favourable. 

Your own home  remains fully CGT-exempt. That has not changed. 

Our View: What This Means for Sydney Property Buyers 

Family homes become more valuable 

The CGT exemption on your principal place of residence has always been one of the most powerful wealth-building advantages available to Australian families. These changes do nothing to alter that — and in a market where investor competition will be reduced, the long-term value of owning your own home, particularly in a supply-constrained area like the Lower North Shore or Eastern Suburbs, has arguably strengthened. 

Renters face a harder road 

Fewer investors buying established property means fewer rental properties entering the market over time. Combined with Sydney’s already acute undersupply, this is likely to put further upward pressure on rents. The government’s intention is to direct investors toward new builds, which takes time to translate into actual supply. In the interim, renting in Sydney’s inner suburbs will become more competitive, not less. 

Investment portfolios will require more careful structuring 

The era of straightforward negative gearing as a tax strategy for established property is ending. Investors who hold both positively and negatively geared assets will increasingly need to think about how those positions work together — offsetting income from one against losses on another to optimise their overall tax position. This is not a reason to avoid property investment; it is a reason to take better advice before you buy. The detail in your personal circumstances matters more now, not less. 

A Note on Timing 

There are 13 months until the new rules take effect. The existing market — and its existing tax settings — remain fully intact until then. For buyers who have been deliberating, that window is worth understanding clearly. 

At Premier Home Finders, we have been buying property across the Lower North Shore and Eastern Suburbs for over 15 years. These changes reshape who is in the market more than they move prices overnight — Sydney’s underlying supply constraints remain the dominant long-term driver of values. But the competitive dynamics are shifting, and buying well in this environment matters more than ever. 

Right now we are helping three types of clients: 

1. Owner-occupiers ready to act while investor competition is easing.

2. Existing investors who want to understand their CGT position before making any decisions. 

3. Buyers considering new builds who want independent advice on locations and project feasibility.
