Singapore Corporate Tax Return Form C/Form C-S

Filing corporate tax returns is a critical responsibility for companies operating in Singapore. The IRAS requires companies to file their tax returns annually using Form C or Form C-S, depending on the company's eligibility criteria. This guide provides an in-depth overview of Singapore’s corporate tax filing requirements, the differences between Form C and Form C-S, and the steps to ensure compliance.

What is Singapore Corporate Tax Return Filing?

Corporate tax return filing is the process of declaring a company’s income, deductions, and tax payable to IRAS for the relevant Year of Assessment (YA). Filing your tax returns accurately and on time ensures compliance with Singapore’s tax regulations and avoids penalties.

Understanding Form C and Form C-S

What is Form C?

• Form C is a comprehensive corporate tax return form for companies with more complex tax filing needs.
• Companies using Form C are required to submit additional supporting documents, such as:
• Financial statements.
• Tax computation.
• Detailed profit and loss statements.

What is Form C-S?

• Form C-S is a simplified version of Form C, designed for smaller companies with straightforward tax affairs.
• Eligible companies only need to declare key financial details without submitting additional supporting documents.

Eligibility for Filing Form C-S

Companies can file Form C-S if they meet the following criteria:

1. Incorporated in Singapore and tax-resident.
2. Annual revenue is S$5 million or less.
3. Derive income that is taxable at the prevailing corporate tax rate of 17%.
4. Do not claim:
• Carry-back of current year capital allowances/losses.
• Group relief.
• Investment allowance.
• Foreign tax credit and tax deducted at source.

Companies that do not meet these criteria must file Form C.
