Registered officers and changes
Corppass does not cap registered officers; the relevant UEN-issuing agency determines the entity requirements. The FAQ says ACRA officer changes reach Corppass within two working days and a new officer need not reappoint an existing administrator. If no officer is available for an urgent appointment, a key executive able to act for the company may approve through an authorisation letter.
Administrator applications and authorisation letters
The letter need not bear a company stamp and may use an overseas telephone contact. Officer and administrator receive email when it is approved. Once an application is sent for officer approval, the applicant cannot withdraw it to choose someone else. Approval must occur within 30 days or the application lapses; alternatively, rejection allows a fresh application. The guide validates the officer’s NRIC.
Administrator identity, access and termination
One administrator may serve multiple entities. A registered officer is identified through the relevant agency’s entity record, such as an owner, partner, director or office secretary. An administrator need not create a second personal user account, but must assign themselves service access if they transact. Termination can be performed by the departing administrator, another administrator, or the registered officer through approved-admin management. An officer without Singpass is directed to [email protected]. The administrator-search service can identify an entity’s administrator or sub-administrator.
Sub-administrators and employee departures
A company should appoint its own employee, not its tax agent, as sub-administrator. A restricted sub-administrator cannot manage services or users outside their assigned profile, authorise/manage third parties or manage client services. Unrestricted rights are broader unless the administrator narrows them. Terminate a departing employee’s account through user management.
Preparer versus approver
A corporate-tax preparer may prepare a form or application and forward it internally, but cannot submit directly to IRAS. An approver can prepare, approve and submit. The company administrator changes that role through user management where required. An existing service assignment alone does not mean the person has final-submission authority.
Tax-agent scope, years and overlapping appointments
Assessment-year limits are optional unless the agent is appointed only for specified years. Multiple firms may be authorised per tax type, subject to checks. Corporate-tax authorisation periods should not overlap; if they do, the firms must cover different assessment years. The FAQ illustrates firms sharing 2020–2021 calendar authorisation dates but one covering YA2020 and the other YA2021. An agent firm cannot be found as a third party until it has an administrator account.
Foreign people and Singapore branches
A foreign director or employee of a local UEN company may apply as administrator using Singpass, subject to the company officer’s approval. A Singapore branch of a foreign company has an ACRA UEN and uses the Singapore-registered-entity flow, not the foreign-entity flow. Passport or foreign-ID changes must be updated in Corppass and notified to IRAS. Do not use an expired FIN as a foreign identifier; choose the foreign-ID type and supply a valid passport or foreign ID.
Login recovery and the historical edition
The FAQ allows six login attempts and describes locking after an unsuccessful sixth attempt, with identifier-retrieval and password-reset routes. This is the version updated on 12 April 2021, including account procedures from that period; present login prompts may differ.
