Yes. Every company, regardless of profit or loss, is required to file annual tax returns with IRAS. Partnering with a trusted corporate services provider in Singapore like Office M ensures that your filings are completed accurately and on time, while also meeting all compliance requirements.
2. What documents are needed for corporate tax filing?
Typically, you will need your financial statements, management accounts, tax computations, and supporting schedules. A reliable corporate secretary provider in Singapore can also assist in maintaining statutory records and preparing the documentation required for smooth tax filing.

Yes. Beyond filing, our tax consultants offer strategic advice on exemptions, deductions, and tax planning to help optimise your company’s tax position.

4. How long does the corporate tax filing process usually take?
The timeline depends on the complexity of your accounts, but most filings are prepared and submitted once we receive all required documents. Companies will generally receive their Notice of Assessment (NOA) from IRAS within the next few months. This document confirms your final tax payable after filing.
5. What happens if my company misses the corporate tax filing deadline?
Late submissions can result in financial penalties from IRAS. If a company fails to file its returns for two or more years, it may even be issued with a Notice to Attend Court/Summons. To avoid such consequences, it is best to work with a professional tax consultant in Singapore. Office M also provides nominee director services to help ensure your company maintains proper governance and compliance with IRAS deadlines.
