Submission and Payment
Submit through desktop Stamp Duty Login > Request > Object to Assessment, by post to the Commissioner at Revenue House, or through the designated Stamp Duty mailbox. Identify the assessment and explain the disagreement with supporting documents. Duty, penalties and other charges must still be paid by their deadlines while the objection is reviewed.
Decision and Further Appeal
IRAS gives its decision in writing. A taxpayer who remains dissatisfied may appeal to the High Court within 30 days of the decision letter. This court deadline is separate from the initial 30-day objection deadline. Keep the notice, submitted evidence and acknowledgement together so the relevant dates remain clear.
