Retrieve the record you are amending
At myTax Portal select Stamp Duty, log in as an individual or business, then choose Request > Amend/ Revise Stamping Record. Enter the Document Ref No. for the record to change. The service opens that record for amendments, so this route changes an existing submission rather than starting an unrelated new stamping record.
Edit and review related sections
The example revises a sale/purchase record’s market value and applicable ABSD rate. Select a section’s Edit icon, change the relevant field such as purchase price/market value, and review later sections for consequential updates. The remission/relief/exemption step indicates eligibility from the revised details; select an applicable type or continue. The guide illustrates this example but does not say all changes produce the same duty or relief result.
Compare charges and declare accuracy
The review page shows current and revised details. The charges summary compares stamp duty, ABSD, penalty, totals, amounts paid and the remaining amount payable, plus a due date. It cautions that recent payments/refunds after the displayed cut-off may not appear. Review, tick the accuracy declaration and submit. The screenshot warns that later amendments can take up to 30 days for review and displays the section 62 warning for false information; do not copy example charges or dates as current rates.
Pending payment and GIRO confirmation are distinct
Choose payment mode and retain Document Ref No. Offline modes such as cheque use Proceed to Acknowledgement. A pending-payment acknowledgement says the account updates after IRAS receives payment and the certificate is generated after receipt. The GIRO example shows pending deduction and warns to keep sufficient funds: a failed deduction invalidates the certificate and there is no second GIRO deduction. Although the screenshot shows a download link, the adjacent guide text ties the certificate to successful payment; check actual deduction status rather than assuming a link proves payment.
