IRAS e-stamping

IRAS was the first in the world to introduce subscription-based electronic stamping or e-Stamping in 1999. The e-Stamping system was further enhanced in Jul 2010 so that users could conveniently e-stamp anywhere and anytime. There are no subscription and transaction fees to this service. Today, adhesive stamps are no longer used and all documents chargeable for Stamp Duty have to be stamped through the e-Stamping system.
