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.
Registered users can self-determine numerous documents on RevenueSA Online, as well as submit documents to the Commissioner of State Taxation for assessment.
RevenueSA Online is an internet based system allowing registered users to self-determine stamp duty, lodge documents for assessment, respond to requisitions (requests for information), generate a Certificate of Stamp Duty and remit payment to RevenueSA 24 hours a day, any day of the week.
A list of the documents that can be self-determined on RevenueSA Online and more detailed information on the various document types is available in the Stamp Duty Document Guide (Self-Determined).
Some document types must be submitted to the Commissioner of State Taxation for an assessment of stamp duty. These documents can be submitted on RevenueSA Online, along with supporting documentation as described in the Stamp Duty Document Guide (Opinions)
With a RevenueSA Online lodgement, an Application for Stamp Duty Assessment form is not required. Just complete the ‘Notes’ field in RevenueSA Online with your submission or include your submission as an attachment.
Notice of Requisition (a request for information) and Notice of Assessment, for documents submitted to the Commissioner of State Taxation for assessment, will be issued by email to your nominated email address.
Some document types require Commonwealth Reporting data to be completed. More details regarding Commonwealth Reporting can be found on the Commonwealth Reporting page including a list of which documents require Commonwealth data.
If you are not a registered RevenueSA Online user, documents can be submitted, along with a completed Application for Stamp Duty Assessment form via:
GPO Box 1353
ADELAIDE SA 5001
RevenueSA Secure Lodgement Box
Customer Services Area
Ground Floor, 101 Grenfell Street
between the hours of 9.00am to 5.00pm Monday – Friday (excluding public holidays)
As manual lodgements take longer to process, to ensure there is no delay in assessing your document, please allow sufficient time for processing. Due to the varying nature of transactions to be assessed, times for processing can also vary. We recommend you allow 10 business days to avoid any inconvenience. If you have concerns over the time frame for a particular transaction, please contact us on 8226 3750.
To ensure your transaction can be processed please include either a transfer form, signed by both parties, or if only one party has signed the transfer, a copy of a fully executed contract (i.e. no outstanding pre-conditions) signed by all parties plus the transfer form.
From 1 July 2019 both vendor and purchaser details are legally required for all Commonwealth reportable transactions and must be provided along with the document for assessment. To facilitate this, you are required to provide the following details for all parties to the transaction:
Additional information required for non-Australian Nationality
