Fourteen or Thirty Days
IRAS states that documents should be stamped before signature. If already signed, no penalty applies when stamping is completed within 14 days after signing in Singapore, or within 30 days after receipt here for documents signed overseas. Signing generally refers to the first signature; a trust instrument is executed when signed, sealed and delivered.
Electronic Documents
Electronic execution and receipt have their own rules, including where a concluding acceptance occurs and where the record is accessed. Follow the electronic-document guide instead of assuming a server’s location controls the deadline. Use myTax Portal’s Stamp Duty Login to stamp and pay; late payment can attract penalties.
