Australia's Capital Gains Tax (CGT) landscape is changing significantly from 1 July 2027, making property valuations more important than ever for investors, business owners, SMSFs, trusts and property-holding entities. According to the Australian Taxation Office, the new rules will replace the traditional 50% CGT discount with a cost-base indexation system and a minimum tax rate on capital gains accrued after 1 July 2027.
For the 3.3 million residential property owners, the value of their property as at 1 July 2027 will become a critical reference point when calculating future capital gains tax liabilities. Should you get an independent valuation, and when should such a valuation be done?
Why an Independent Valuation of Your Investment Property Matters
To determine the cost base for the calculation of capital gains, property owners will have the choice of using the government's default formula for calculating capital gains over the entire period of ownership, or splitting the capital gains between pre & post 1 July 2027 by getting an independent market valuation as at 1 July 2027.
The ATO's focus is not simply on obtaining a valuation, but on ensuring that the valuation is independent, evidence-based, and capable of withstanding review years later. A properly prepared valuation establishes a defensible cost base and helps minimise audit risk
The key phrase from the ATO's guidance is that valuations must be "objective and supported with appropriate evidence."And states that the valuation report should contain:
- The purpose of the valuation.
- Details of the property.
- The valuation date.
- The basis and methodology used.
- Supporting evidence and analysis.
- The concluded market value.

For many property investors, obtaining a professional market valuation as at 1 July 2027 isn’t just about record keeping, it may mean the difference between thousands of dollars in extra tax.
Taxpayers have the right to get an independent market valuation, and then choose whichever method yields the lower overall tax liability, but only if they have a formal valuation report to back up their numbers. Remember that the burden of proof falls entirely on the taxpayer to prove what their asset was worth as at 1 July 2027. If an investor wants to opt out of or challenge the default formula, they must have supporting evidence of the value of their investment property as at 1 July 2027. A comprehensive market valuation is the soundest form of evidence. Â
Why Timing Matters
Under the new CGT framework, gains accrued before and after 1 July 2027 may be treated differently. This means establishing a defensible market value at the transition date could become one of the most important tax records you hold.
The ATO does not require you to have the valuations in hand by 1 July 2027, and valuations cannot be completed before that date. The valuation is only strictly required when you eventually sell the property in the future. If a valuation is undertaken after 1 July 2027, the valuer will perform a retrospective valuation. A retrospective valuation involves a current physical inspection of the property and the use of historical data frameworks to reconstruct what the market and the property value was specifically on 1 July 2027. Local valuation firms have operated in the market often for many decades and have sound historic data and to support a retrospective assessment.
As the Australian Property Institute notes, valuations undertaken close to the relevant valuation date are generally more credible and defensible than attempting to reconstruct a property's value many years later, but retrospective valuations are also able to be carried out at some point in the future.
The Risk of Waiting Too Long
While a retrospective valuation can be carried out months or years later, property markets move constantly, and by the time a property is sold, it may be five, ten or even twenty years after the CGT transition date. Waiting until then to establish a historic value can create several challenges:
- Valuation costs can increase.
- Property improvements and changes may be hard to verify.
- The ATO may scrutinise unsupported or poorly documented estimates.
‍
A properly prepared valuation completed at or near the relevant date provides a contemporaneous record that can help support your tax position in the future.
Who Should Consider a Valuation?
Property valuations may be particularly important for:
- Residential investment property owners
- Commercial property investors
- Property held within trusts
- Self-Managed Super Funds (SMSFs)
- Family offices
- Primary producers and rural landowners
- Business owners holding property within company or trust structures

If you expect to hold property beyond 1 July 2027, now is the time to begin planning with your accountant and valuation adviser.
What Type of Valuation Is Best?
Not all valuation products are equal.
Online estimates, automated valuation models and property website price guides are not valuations. They can provide an indication of value, but they are generally not a substitute for an independent valuation report prepared by a qualified Certified Practising Valuer.
The “Gold Standard” is a comprehensive market valuation with physical inspection, which provides the highest level of data integrity. It eliminates any doubt regarding the property’s market value.
Desktop or automated valuations carry risk. The ATO heavily scrutinises valuations. An uninspected desktop appraisal that relies purely on automated algorithms or external property data is highly vulnerable to being challenged and overturned by the ATO.
For important tax-related matters, a full inspection valuation by a certified practising valuer provides the strongest level of evidence and is typically the most defensible if your position is later reviewed.
The Expected Demand Surge
Across the valuation industry, there will be significant demand for CGT-related property valuations as the transition date approaches.
CivicIPN has identified growing demand for:
- CGT reset valuations
- Retrospective valuations
- SMSF property valuations
- Trust and business restructuring valuations
- Commercial and rural property assessments
‍
Demand for bookings is expected to accelerate substantially as 1 July 2027 draws closer. It is highly likely there will be increased valuation activity across the accounting, advisory and property sectors in preparation for the transition date. However, unless you are planning on selling your property around 1 July 2027, a retrospective valuation undertaken up to 12 months after this date is feasible, acceptable and supportable. Â
Our Recommendation
If you own property that may be affected by the new CGT rules, do not leave valuation planning until the last minute.
Property owners who may wish to rely on a market value at the CGT transition date should consider reaching out to a local valuation firm prior to 1 July 2027. Otherwise, you don’t need to rush, the ATO does not require you to have a valuation report in hand by July 2027. A retrospective valuation can be done after 1 July 2027
The cost of obtaining a professional valuation today may be insignificant compared with the potential tax consequences of an unsupported value in the future. We recommend speaking to your accountant or tax advisor if you are unsure or need further advice.
