2027 CGT Property Valuation Adelaide & South Australia
For some South Australian investment property owners, a well-supported 30 June 2027 market value could become an important future tax record. Australia's capital gains tax rules change from 1 July 2027, creating a transition between gains accrued under the existing CGT discount rules and gains arising under the new indexation system.
Valuations SA prepares independent current and retrospective valuation reports throughout Adelaide and South Australia for taxation purposes, including a capital gains tax property valuation in Adelaide for the upcoming 2027 transition.
What Changes to CGT From 1 July 2027?
From 1 July 2027, the existing 50% CGT discount is replaced for eligible Australian resident individuals and trusts by CPI-based cost base indexation for qualifying assets held for at least 12 months. The rules also extend to relevant gains attributable to individuals through partnerships.
A 30% minimum tax applies to relevant real capital gains accruing from 1 July 2027. This operates as a minimum rather than automatically making every capital gain taxable at exactly 30%.
The reform is prospective. Eligible gains accrued before 1 July 2027 retain their treatment under the previous rules, including the 50% CGT discount where applicable. The existing main residence exemption is also retained.
Why the 30 June 2027 Market Value Matters
For eligible assets already held across the transition, the legislation generally treats the asset as sold immediately before 1 July 2027 and reacquired immediately afterwards.
Under the default approach, the amount used for that transition is the asset's market value at the end of 30 June 2027. The resulting pre-transition gain or loss is deferred until a later realisation event, such as the eventual sale of the property.
Taxpayers may instead be able to choose an authorised apportionment method. Treasury's published method estimates the transition value by assuming the asset grew or declined at a constant compounded daily rate over the ownership period.
Why Actual Adelaide Market Conditions Can Matter
Property markets rarely grow at a perfectly constant rate.
Consider a long-held retail shopfront in Norwood. Its value may have changed considerably as retail demand, tenancy conditions, interest rates, redevelopment activity and surrounding commercial property values shifted over different market cycles.
A mathematical growth assumption may therefore produce a different transition figure from a valuation based on actual comparable transactions and property-specific evidence around 30 June 2027. For property held before this reform, we also prepare a retrospective property valuation in South Australia dated to a specific historical point in time.
A valuation does not guarantee a tax saving. It establishes independent market evidence that your accountant or tax adviser can use when considering the available CGT calculation methods. We also prepare an independent market property valuation for current transactions, refinancing, and other non-CGT purposes.
Who Should Review Their Position Before 1 July 2027?
A 30 June 2027 valuation may be relevant to eligible taxpayers holding non-exempt property across the transition, including owners of:
- Residential investment houses and units
- Retail and commercial premises
- Industrial property
- Development sites
- Rural and agricultural property
- Property held through relevant trusts or partnerships
Inherited assets and deceased estates can involve additional CGT rules. Companies, superannuation funds, foreign residents and temporary residents are also subject to different provisions in parts of the new regime.
Property owners should confirm their individual requirements with an accountant or qualified tax adviser before commissioning a valuation.

2027 CGT Property Valuation FAQs
What Is a 30 June 2027 CGT Valuation Used For?
It establishes independent evidence of the property's market value immediately before the new CGT rules begin. For eligible property held across 1 July 2027, that figure can be used to separate gains accrued under the previous CGT rules from gains arising under the new indexation regime.
Does the Deemed Sale on 30 June 2027 Create an Immediate Tax Bill?
No. The legislation creates a deemed sale and reacquisition for calculation purposes, but the resulting pre-transition gain or loss is generally deferred. It is brought into account when a later realisation event occurs, such as when the property is eventually sold or otherwise subject to a relevant CGT event.
Must I Obtain a Professional Valuation Instead of Using Apportionment?
No. Market value is the default transition basis, but eligible taxpayers may choose an authorised apportionment method where available. A professional valuation provides property-specific evidence, while apportionment estimates the transition amount mathematically. Your tax adviser should assess which method is appropriate for your circumstances.
Why Could the Apportionment Result Differ From an Adelaide Property Valuation?
The published apportionment method assumes a constant compounded daily rate of growth or decline over the ownership period. Actual Adelaide property values can rise, fall or remain stable at different times, so a formula-derived transition amount may differ from market value supported by comparable sales around 30 June 2027.
Does the 30% Minimum Tax Mean Every Capital Gain Is Taxed at 30%?
No. The 30% measure operates as a minimum tax on relevant post-1 July 2027 real capital gains. Where the gain is already effectively taxed at 30% or more, the minimum tax does not simply replace that rate. Individual outcomes depend on the taxpayer's circumstances and should be confirmed professionally.
What Records Should I Keep for a Future Retrospective Valuation?
Keep documents showing the property's condition and characteristics around 30 June 2027, such as photographs, plans, tenancy information, renovation records and details of major improvements. Valuations SA can prepare retrospective reports later using historical sales evidence, but good contemporaneous records can strengthen the valuation process — particularly if you later require a retrospective property valuation in South Australia.
