1. My company ceased business during the financial year ending 31 Mar 2024 and intends to apply for strike off. If the company has used the Apply for Waiver/ File last Form C-S/ C (Dormant/ Striking Off) digital service and filed the Form C-S/ Form C-S (Lite)/ Form C, financial statements and tax computation up to the date of cessation of business (i.e. the Year of Assessment (YA) 2025), is it still required to file the Estimated Chargeable Income (ECI) for YA 2025?

   Your company is not required to file the ECI for YA 2025, as it has already filed the Form C-S/ Form C-S (Lite)/ Form C, financial statements and tax computation for that YA. We will review and finalise the YA 2025 assessment based on the Form C-S/ Form C-S (Lite)/ Form C, financial statements and tax computation filed.

2. My company received a notification from the Accounting and Corporate Regulatory Authority (ACRA) informing us that IRAS has lodged an objection to the company’s striking off application. What should the company do?

   IRAS will lodge an objection to your company's application for strike off if your company has outstanding tax matters. Your company is required to resolve the objection on the outstanding tax matters within 2 months from the date the objection is lodged. Otherwise, your company's strike off application will lapse and you will need to apply to ACRA for strike off again.

3. My company has been struck off/ has amalgamated with another company. Am I still able to access mytax.iras.gov.sg to view and/or download my company’s Corporate Income Tax notices?

   A company ceases to exist when it has been struck off or has amalgamated with another company and it is not the surviving entity of the amalgamation. Access to Corporate Income Tax digital services at mytax.iras.gov.sg, including the View Corporate Tax Notices/ Letters digital service, will no longer be available as there is no further need for the company to transact with IRAS. Should your company require its Corporate Income Tax notices, you must arrange for the notices to be downloaded and saved prior to its strike off with ACRA or date of amalgamation.

Section 377(1) of the Companies Act 1967 requires the Singapore branch of a foreign company to lodge a notice with the Accounting and Corporate Regulatory Authority (ACRA) within 7 days after it ceases to have a place of business or to carry on business in Singapore.

The branch should also inform IRAS in writing at the same time that it informs ACRA so that the tax matters and tax liabilities of the Singapore branch can be settled.

The written notification to IRAS must include:

• Subject header 'Cessation of Business in Singapore'
• Date of cessation of business in Singapore in dd/mm/yyyy format
• Name and contact details of a person whom IRAS can liaise with on tax matters
• All outstanding Corporate Income Tax Returns (Form C), financial statements and tax computations up to the last day of business

Generally, IRAS strives to complete all assessments within 1 month of receipt of complete information. However, in the event that IRAS requires further information from branches with more complex affairs or the branches have submitted incomplete information, IRAS may take up to 6 months to review the assessments.
