From 1 September 2018, CorpPass will replace the existing EASY authorisation system and the login method for the e-filing of GST returns.
The Singapore Corporate Access (CorpPass) is a one-stop authentication and authorisation service for corporate users to transact with government agencies online on behalf of their organisations. It is essentially a corporate digital identity for businesses.
From 1 September 2018, CorpPass will replace the existing e-Services Authorisation System (EASY) and will be the only authorisation system for the e-filing of GST returns. Businesses will no longer be able to login to the Inland Revenue Authority of Singapore’s (IRAS) myTax Portal using SingPass or the IRAS PIN after 1 September 2018.
