Company login category
The company edition starts at myTax Portal and uses the business-tax login category. It describes how an individual acting for a company reaches the portal, rather than how the company applies for a new UEN.
Using the Singpass app
Open myTax Portal and choose the appropriate login category. In the April 2021 guide, app authentication involves scanning the displayed QR code, confirming the login request in Singpass and verifying your identity using supported fingerprint or facial authentication, or the six-digit app passcode. The guide restricts Singpass Foreign users to this app route.
The password and second-factor route in this edition
The alternative shown for other users starts with the Singpass identity and password. The guide then offers SMS verification using a six-digit code sent to the registered mobile number, or face verification. The facial route requires a device with a front-facing camera, asks the user to read the scanning guidance and follow the on-screen scan instructions, and advises against this method for people sensitive to flashing lights. These are the options in the 2021 document, not a guarantee that every option remains available today.
Selecting the entity and foreign-user reference
Where more than one Corppass account is associated with the login, the guide displays an entity-selection step. Choose the relevant UEN or entity identifier. Singpass Foreign users are also directed to enter the tax reference assigned by IRAS before continuing. Entity selection and personal identity verification serve different purposes.
Opening a service and version context
After selecting the entity, choose the required electronic service from the navigation bar. IRAS published this edition on 5 April 2021. Its screenshots and authentication sequence should be understood as a record of that edition; use the current portal prompts where they differ. Questions about the guide are directed to IRAS through myTax Mail or the telephone channel identified in the PDF.
