What is a valuation assessment amalgamation?

Amalgamation is the combining of two or more parcels of land into one assessment, for valuation reasons or required by law.

Requesting an amalgamation of land:

A property owner can request individual parcels they own be amalgamated into one valuation assessment for rating and taxing purposes, but the Valuer-General is not obliged to do so.

The Valuer-General cannot amalgamate land into one assessment simply to meet the needs of the property owner.

There has to be a valid reason to do so and the parcels of land need to be:

  • contiguous to each other, and
  • held in the same ownership, and
  • used in conjunction with each other in a way that the parcels of land cannot be sold advantageous from each other, or
  • the amalgamation is required by law

When applying for a valuation assessment amalgamation, you'll need to provide:

  • property valuation numbers.
  • address of the property and postal address, if different.
  • authority to act for the property owner if the applicant is not the registered proprietor.
  • contact phone number.

No formal application form is required, however applications are required to be submitted in writing. Please forward your request to:

Email: OVGobjections@sa.gov.au
Post: Office of the Valuer-General - GPO Box 1354, Adelaide SA 5001

Once assessed, correspondence will be provided to the applicant outlining relevant details.

It should be noted that:

  • depending on the circumstances, some amalgamations may not come into force until the following financial year.
  • the purpose of the Valuer-General is to provide fair and equitable valuations. Therefore, valuation assessments are not altered to achieve a rating outcome.
  • Legal descriptions such as Certificate of Title and allotment/plan details are not changed due to a valuation assessment amalgamation.
