Start with returns through cessation
Day 0 in the chart is submission of Form C-S, Form C-S (Lite) or Form C through the business-cessation date, together with tax computations and financial statements where applicable. From 1 August 2026, companies seeking strike-off must file advance Years of Assessment up to cessation using Apply for Waiver/ File last Form C-S/ C (Dormant/ Striking Off). The diagram links completing these tax matters to the Singapore company’s subsequent ACRA strike-off application.
Straightforward cases and payment
The chart places approximately 80% of companies in the straightforward route: IRAS completes assessments by the second month, and the company pays any assessed tax within 30 days of the Notice of Assessment. The month labels describe the chart’s processing route; payment is measured from the actual notice date.
Complex cases and enquiries
Approximately 20% follow the complex route. IRAS issues requests for further information by month two, companies respond by month four, and IRAS completes assessments by month six. The flowchart describes an expected sequence; it does not eliminate the company’s responsibility to provide information or settle liabilities.
Foreign-company branches have separate notice duties
A Singapore branch of a foreign company must lodge an ACRA notice within seven days after ceasing business in Singapore, tell IRAS at the same time, and provide a contact person and details. ACRA records the cessation as soon as practicable after lodgement. The foreign company remains liable for tax for the pre-cessation period, and IRAS works with the contact person to resolve outstanding matters and liabilities. This branch process differs from the Singapore-company strike-off path in the chart.
