Authorisation and functional currency
Company or appointed-agent staff require Corppass authorisation to view/access corporate information. Only an Approver may update contact details or functional currency. For functional currency the authorisation must be Corporate Tax (Filing and Applications); non-SGD currency should be updated before Form C-S, C-S Lite or C filing. An inability to edit may therefore reflect role or service authorisation rather than missing currency support.
ACRA records and foreign-company exception
ACRA-registered companies update address/year-end through the source’s BizFile+ route. IRAS refreshes changes filed Sunday–Saturday by the following Friday: the example 6–12 March 2022 is updated by 18 March. Foreign companies not registered with ACRA can instead have an authorised company/agent Approver request those changes in the portal, processed within three working days and checked by logging in later. Other online changes such as contact details/currency update immediately upon successful submission.
