New initiative to manage your individual client's income tax matters via myTax Portal

IRAS has launched a new initiative to allow individual taxpayers to authorise their tax agents to access their myTax Portal accounts on their behalf via an Authorisation Code.

From 15 Mar 2019, a tax agent who has been authorised to access his client's myTax Portal account on his client's behalf can e-Transact with IRAS (e.g. file tax return) and access the following suite of digital services using his CorpPass ID and Authorisation Code.

To request for an Authorisation Code, please get your client to download and complete the application form (308KB).
