IRAS | Corppass

From 11 Apr 2021, you will be required to log in to government digital services for businesses (G2B) using Singpass instead of Corppass. For more information, visit Corppass website.

Singapore Corporate Access (Corppass) is an authorisation system for businesses to grant access to their employees and third parties (e.g. tax intermediaries) to perform digital transactions with government agencies online. To access IRAS’ digital services in myTax Portal business account, employees and third parties must first be authorised via Corppass.

The table below shows the list of IRAS digital services that require Corppass. We have added a new digital service for Enterprise Innovation Scheme (EIS).
