Authorisation and login
Use Company/Business Tax when acting for the company, or Tax Agent Login > Business Client for a client. Both require the company’s Corppass Corporate Tax (Filing and Applications) authorisation. After Singpass login, choose Corporate Tax > Request Extension of Time to File from Overview.
Enter request details
Select YA, designation, contact number and email, then SUBMIT. Without a local number, tick the foreign-number option and supply country code, area code and foreign number. The 26 August 2024 guide says the current-YA extension becomes available only after 30 November. It does not say the applicant may ignore the original due date or guarantee extension approval.
Confirm and retain the outcome
CANCEL returns to Enter Details for correction; OK confirms. Read the Result page, save/print it and retrieve a stored copy at Notices/ Letters > Corporate Tax. Check the actual outcome rather than treating request submission as automatic approval; the guide does not state a universal extension length.
