Understanding the Structure and Content of Your NOA

How Your Tax Liability is Calculated in the NOA

The Singapore tax assessment is based on a comprehensive review of data from the taxpayer's declaration and third-party sources. If a tax return is not filed on time, IRAS may issue an Estimated Notice of Assessment based on information available to it. Such an estimate typically does not account for deductions and reliefs and is payable until a correct return is filed, leading to a revised NOA.

What to Do If You Find an Error: Filing an Objection to NOA

The taxpayer is responsible for thoroughly reviewing the NOA. If discrepancies are found, the standard legal mechanism is to file a formal Objection to NOA. This process is formalized with strict rules:

• Filing Deadline: A written objection must be submitted to IRAS within 30 days from the date stated on the NOA.
• Form and Content: The objection is filed electronically via the myTax Portal and must clearly state the NOA number, Year of Assessment, and a detailed justification with supporting documents.
• Review Process: IRAS reviews the objection and may request additional clarifications, resulting in either a Revised Notice of Assessment or a confirmation of the initial assessment.
