Stamp duty is a charge on certain documents and transactions. Stamp duty is charged at either a flat rate or an ad valorem rate (based on the value of the transaction) depending on the particular document or transaction.
There are three different methods for lodgement, determination and payment for South Australian Stamp Duty Documents:
RevNet is an internet based system allowing approved clients to transact with RevenueSA 24 hours a day.
Some document types must be submitted to the Commissioner of State Taxation for an assessment of stamp duty. These documents must be submitted with a completed Application for Stamp Duty Assessment form and supporting documentation as described in the Stamp Duty Document Guide (Opinions).
The front counter, located in Taxpayer Hall, Ground Floor State Administration Centre Adelaide is open Monday - Friday from 10:00am - 2:00pm on business days to provide counter assessment services for infrequent (10 documents or less per year) non RevNet users. Documents are to be presented to the counter with a completed Application for Stamp Duty Assessment form and supporting documentation where required. Immediate assessment will not apply to document types requiring Opinion Assessment. You can access Taxpayer Hall between the hours of 9:00am to 5:00pm on business days to access the delivery boxes and to lodge Opinion Assessments via the secure lodgement box.
