Short answer
A CGT property valuation assesses market value for a specified property interest and valuation date. It provides evidence for the client and their accountant or tax adviser.
The adviser determines whether the tax rules require market value evidence and confirms the relevant date. Northbourne Valuers assesses the property’s market value for the agreed instruction, with valuation enquiries considered across Canberra, the ACT and surrounding NSW.

CGT valuation instructions often depend on the event, property history and date required by the accountant or tax adviser.
A current valuation and a retrospective valuation may require different evidence. The valuation date must be clear before the report is prepared.
Where the valuation is retrospective, the valuer considers the property and market evidence as at the historical date, not simply the current market.
CGT changes from 1 July 2027 may make a transition-date value relevant for some properties already held before that date. The required valuation date and the date a report is commissioned are separate matters. Read CGT Changes from 1 July 2027: When Is a Property Valuation Relevant? for the deemed sale/reacquisition provisions, the statutory alternative and later determination of the relevant amount.
Information that may assist
Useful documents may include purchase records, settlement documents, historical photographs, renovation dates, lease details and accountant instructions.
If the required date is unclear, the client should obtain advice from their accountant or tax adviser before instructing the valuation.
