This article is a point-in-time announcement describing IRAS administrative procedures as they stood in October 2018 — it is not a statement of current IRAS practice. Portals, e-Services, contact email addresses, and filing requirements referenced below (such as mytax.iras.gov.sg, the specific e-Service names, and ctmail@iras.gov.sg) may have since changed. Confirm current procedures directly on the IRAS website before acting on anything in this article.
Request for Income Tax Return (Form C-S/C) and Notification of New Financial Year End
In the past, a hard copy form had to be submitted to the Inland Revenue Authority of Singapore (“IRAS”) to request an Income Tax Return (Form C-S/C) for new companies. However, this was no longer a requirement with effect from 18 October 2018. Companies required to file their first corporate tax return for YA 2018 could proceed to e-File the return directly via the File Form C-S/C e-Service, with no need to request a YA 2018 return from IRAS.
Request for Income Tax Return (Form C-S/C) for Companies Previously Granted a Waiver
Another update IRAS announced in October 2018 related to requesting an Income Tax Return (Form C-S/C) for companies previously granted a waiver from submitting a tax return. If such a company recommenced business or started receiving income in 2017, it could email ctmail@iras.gov.sg to request an Income Tax Return for YA 2018, providing:
- Subject header: “Recommencement of business and request for Income Tax Return”;
- Name and Unique Entity Number (UEN) of the company;
- Date of recommencement of business and new principal activity (if applicable); and
- Date of receipt of other source(s) of income, e.g. interest, dividend, rent, etc. (if applicable).
Update of Financial Year End
Companies that changed their financial year end could update IRAS directly by logging in to mytax.iras.gov.sg and using the “Update Corporate Profile/Contact Details” e-Service.
Change of Company Name and Registered Address
When a company changes its name and/or registered office address, the change is filed with the Accounting and Corporate Regulatory Authority (ACRA) online via www.bizfile.gov.sg. There is no need to separately inform or update IRAS — IRAS updates its records based on information filed with ACRA on a weekly basis.
Update of Functional Currency
If a company’s functional currency is not Singapore Dollar, it must inform IRAS by logging in to mytax.iras.gov.sg and updating it via the “Update Corporate Profile/Contact Details” e-Service.
