2027 CGT Property Valuation Perth & Western Australia
From 1 July 2027, Australia's capital gains tax rules change for eligible individuals, trusts and partnerships. For Western Australian investment property held across the transition, the market value at the end of 30 June 2027 can become the dividing point between gains accrued under the existing rules and gains subject to the new regime.
West Coast Valuers can provide an independent capital gains tax property valuation for the required date, giving your accountant or tax adviser documented market value evidence to use when assessing your CGT position.
What Changes to CGT From 1 July 2027?
From 1 July 2027, the existing 50% CGT discount will be replaced for eligible taxpayers by CPI-based cost base indexation, together with a 30% minimum tax on relevant real capital gains accruing after the transition date.
Gains attributable to the period before 1 July 2027 remain subject to the previous rules. This means the value of an investment property immediately before the new regime begins can become important when determining how a future capital gain is divided between the two periods.
The existing main residence exemption continues, while different rules apply to certain taxpayers and ownership structures.
Why the 30 June 2027 Market Value Matters
Where the market value method is used, an eligible asset held across the transition is effectively treated as sold immediately before 1 July 2027 and reacquired at that value.
This makes the property's market value at the end of 30 June 2027 an important reference point when calculating the portion of a future capital gain attributable to the period before and after the CGT reform.
Having an independent valuation can provide property-specific evidence rather than relying solely on a mathematical estimate that may not reflect actual market movements.
Market Value Versus the Apportionment Method
Treasury has proposed an alternative apportionment method for certain real property. The method estimates the property's 30 June 2027 value by assuming a constant compounded daily rate of growth or decline throughout the ownership period.
That assumption may not reflect the actual performance of every Western Australian property market.
For example, a Pilbara investment property may have experienced rapid growth during a resources boom, followed by a significant correction and later recovery. A smooth-growth calculation may produce a materially different figure from a valuation based on actual comparable sales and market evidence around 30 June 2027.
A professional valuation does not guarantee a lower CGT liability. It provides independent evidence that your accountant or tax adviser can consider when determining the appropriate tax treatment.
Who May Need a 2027 CGT Property Valuation?
The reform is particularly relevant to Australian resident individuals, partnerships and trusts holding non-exempt property across 1 July 2027.
Property types that may require consideration include:
- Residential investment properties
- Apartments and townhouses held for investment
- Commercial property
- Industrial property
- Rural and agricultural property
- Property held within family or discretionary trusts
- Property forming part of certain deceased estates
Companies, superannuation funds including SMSFs, life insurers, foreign residents and temporary residents are not subject to the headline reform in the same way. Owners should obtain advice from a qualified accountant or tax adviser about how the legislation applies to their circumstances.

2027 CGT Property Valuation FAQs
What Date Should My CGT Valuation Use for the 2027 Reform?
The relevant transition value is the property's market value at the end of 30 June 2027, legally expressed as immediately before 1 July 2027. Your accountant or tax adviser should confirm the appropriate valuation basis for your circumstances before you commission the report.
Is a Professional Property Valuation Compulsory?
No. The legislation allows market value to be used and also provides for an authorised apportionment method for certain assets. An independent valuation is therefore not compulsory in every situation, but it can provide stronger property-specific evidence where a formula may not accurately reflect actual market movements.
How Does the Proposed Property Apportionment Method Work?
The proposed method estimates the property's 30 June 2027 value by assuming it increased or decreased at a constant compounded daily rate throughout the ownership period. This provides an alternative to obtaining a formal valuation, although the resulting figure may differ from actual market value in cyclical property markets.
Can a 30 June 2027 Valuation Reduce My Capital Gains Tax?
A valuation does not automatically reduce your tax liability. It establishes independent evidence of the property's market value at the transition date. That value may influence how a future gain is divided between the pre-2027 and post-2027 CGT regimes, with the final tax treatment determined by your tax adviser.
Does the 2027 CGT Reform Affect My Main Residence?
The existing main residence CGT exemption continues. However, additional rules may apply if the property has been rented, used to produce income or only qualified as your main residence during part of the ownership period. Your accountant should confirm the relevant exempt and taxable portions.
Does an SMSF-Owned Investment Property Need This Valuation?
Not specifically because of this replacement of the 50% CGT discount. The reform does not apply to superannuation funds, including SMSFs, in the same manner as eligible individuals and trusts. SMSFs have separate valuation and compliance requirements, so trustees should obtain advice from their accountant or auditor.
Can West Coast Valuers Prepare the Valuation After 30 June 2027?
Yes. West Coast Valuers provides retrospective property valuations in WA and can determine market value for a historical date using appropriate contemporaneous evidence. However, arranging the valuation around the transition date may make it easier to preserve relevant records and access market evidence from that period.
