Retrospective Property Valuation

What is a retrospective property valuation?

A retrospective property valuation determines the value of a property at a particular point in the past. Unlike a standard current market valuation, a retrospective valuation (also known as a historical property valuation or backdated property valuation) is used to assess a property’s market value as it stood on a chosen date.

Whether you’re calculating capital gains tax, resolving a legal dispute, or preparing for estate distribution, a retrospective property valuation provides the evidence you need based on historical market value and comparable sales data from that time.

These valuations are carried out by certified practising valuers using reliable historical market data to provide accurate valuations that comply with relevant legal and taxation standards. This type of historical valuation of property is especially useful when the current market no longer reflects the property’s past conditions or value. 

When and why you might need a retrospective valuation

There are several reasons why individuals, businesses, and legal professionals require a retrospective valuation. Common use cases include: 

  • Capital Gains Tax (CGT) obligations – particularly for investment properties purchased before CGT was triggered
  • Deceased estates – to calculate the fair market value at the date of inheritance
  • Family law proceedings – for equitable and fair division of property
  • SMSF and ATO reporting – requiring valuations at historical dates for compliance
  • Business restructuring or financial audits – where backdated assessments are needed

In each case, a certified valuation based on a specific past date helps meet tax obligations, support legal claims, or satisfy accounting requirements. 

Retrospective Valuation for CGT (Capital Gains Tax)

Capital gains tax is one of the most common reasons property owners require a retrospective valuation. If you’ve acquired an asset prior to CGT changes or you’re declaring a property’s value at the time it became income-producing, the Australian Tax Office (ATO) may require an accurate assessment of its historical market value.

Acumentis provides retrospective valuation for CGT purposes that aligns with ATO guidelines, delivering professional valuation reports suitable for audits, tax returns, and financial records.

Each valuation is prepared by a certified practising valuer with access to historical market data, ensuring you receive a defensible valuation that reflects the property’s value at a specific point in time.

Our Process

Our goal is to make the valuation process straightforward and dependable. Here’s how it works:

  1. Initial Enquiry – You tell us the property details and the specific historical date needed
  2. Data Gathering – We access historical market data and analyse comparable sales from that period
  3. Certified Valuation – One of our API-certified valuers prepares the backdated valuation
  4. Delivery – You receive a legally compliant valuation report suitable for tax, legal, or financial purpose

We take into account market conditions, property characteristics, and available sales evidence from the relevant timeframe to deliver an accurate and defensible result. In many cases, we also consider original valuations (such as those completed at the time of purchase) to provide additional context on how the property’s value has changed over time.
