Stamp duty is the name of the tax payable upon transfer of ownership of an asset between two or more parties. A stamp duty valuation is required when transferring ownership between related parties or where property is being transferred into a superannuation fund or various other trusts and legal entities. The stamp duty tax is then payable based on the valuation report provided by a registered valuer. Often a property is sold between related parties and is significantly below market value in which case you will need to have a stamp duty valuation to determine market value. Stamp duty valuation reports contain information on the physical attributes of the property, current market sales evidence and professional interpretation and valuation rationale.
