Authorisation and login routes
Before requesting more time, ensure that the business has authorised you in Corppass for partnership Form P filing. A person acting directly for the business uses the company/business-tax route; a tax agent acting for a client uses the business-client route under tax-agent login. Authenticate using Singpass as a Corppass user, then open the partnership extension service from the overview page.
Select the assessment year and designation
The request page asks for the applicable Year of Assessment and the applicant’s designation. If more than one assessment year is eligible, choose the relevant year; if only one qualifies, it is pre-selected. The document states that requests for the current assessment year become available only after 18 April. Continue once these details are complete.
Review, submit and read the result
Check the information on the review page. Return to the request page if a correction is needed; otherwise submit the request. The outcome is displayed on the result page. An application is therefore not complete merely because the review screen has been reached, and submission does not itself mean the extension was granted.
Keep the result and understand the version
Print or save the result as a PDF. The guide states that a copy is also stored in the partnership notices/letters area. The publication page says 18 August 2025, while its general disclaimer retains an earlier correctness-date string; this article reports the workflow shown in that PDF without treating that discrepancy as a new legal filing rule.
