Opening the service and viewing company particulars
After signing in, select Account > Update Corporate Profile/Contact Details. The overview shows name, tax reference, company type and status, registration or incorporation place and date, and place of control and management, with financial year-end and functional currency. Inform IRAS through myTax Mail if displayed particulars are wrong.
Financial year-end: the ACRA distinction
For a company not registered with ACRA, only an authorised Approver may change the financial year-end here: enter it, Save, then confirm Yes. An ACRA-registered company instead changes its financial year-end with ACRA; information is transmitted to IRAS periodically. The guide uses the historical BizFile+ service name.
Functional currency
An Approver may select the non-Singapore-dollar currency used to present the financial statements. If it is absent from the list, select the option for currencies other than S$. Save and confirm Yes. This field describes the company’s functional currency; it does not independently set an exchange rate.
Local address for a non-ACRA company
An Approver selects Edit Company Address, Singapore, and the postal code, then Retrieve. Select block or house number, add unit number if applicable and the new address’s effective date; Save and confirm Yes. Processing generally takes three working days. For ACRA-registered companies, change the address with ACRA for periodic transmission to IRAS instead.
Foreign address
Select Edit Company Address, country or territory, address and effective date; Save and confirm Yes. The same limits apply: direct editing is for an Approver of a non-ACRA company, generally processed within three working days. ACRA-registered companies update through ACRA.
Contact information
Only an authorised Approver can change contact details. Enter the information, Save and confirm Yes in the pop-up. Updating tax contact information is distinct from changing the registered particulars through ACRA.
Acknowledgement and guide date
On successful submission an acknowledgement appears. Use Save As PDF/Print to keep a copy, or select Overview to return home. The ten-page guide was published on 6 May 2022 and gives 1800 356 8622 and myTax Mail for enquiries. Its menu labels and service names describe that edition.
