Authorising a Tax Agent for Individual Income Tax

An individual can grant or terminate tax-agent access through “Manage Tax Agent Authorisation” in myTax Portal, using Singpass or a Singpass Foreign user Account.

Source checked · 11 October 2026

What authorised agents can do

Authorised agents can use individual-income-tax services for filing, tax-bill amendments, filing extensions, payments, account and GIRO information, penalty appeals, notices and myTax Mail. Tax firms must also authorise their staff in Corppass and assign the IRAS “Individual Income Tax (Filing and Applications)” service.

Access and contact safeguards

Access is restricted to Individual Income Tax services. Agents may view earlier records, except myTax Mail sent before 12 August 2024. They should not replace the client’s address or mobile number with their own unless specifically authorised to receive correspondence on the client’s behalf. Without authorisation, IRAS cannot disclose or assist with the client’s individual tax matters.
