In Singapore’s financial ecosystem, the IRAS Notice of Assessment (NOA) stands as a cornerstone for income verification, loan applications, and tax transparency. Issued annually by the Inland Revenue Authority of Singapore, this document details your earnings, allowable tax deductions, chargeable income, and the final tax amount payable for a specific Year of Assessment. For residents managing personal finances or handling official processes like home loan approvals or visa applications, understanding and retrieving your NOA is essential.
Breaking Down What the IRAS NOA Really Is
Your NOA acts as an official confirmation of your tax status. It contains a breakdown of your assessable income, deductions you’ve claimed, the chargeable portion of your income, and the total tax you owe. Typically, this document is issued after you’ve submitted your income tax returns. If you’re employed, this is often processed automatically by your employer under the Auto-Inclusion Scheme. However, self-employed individuals or landlords are required to file their income manually before receiving the NOA.
Key Reasons Why Your NOA Is More Than Just a Tax Bill
Far beyond being a tax summary, the NOA plays a vital role in proving your financial stability and fulfilling administrative requirements. When applying for a bank loan, public housing, or a new visa, your NOA is one of the first documents that institutions request. It also confirms your annual earnings and helps you detect errors in your tax submissions. If there are discrepancies, you can raise an objection and seek adjustments.
Retrieve Your NOA in Minutes via Digital Access

Singapore’s tax system has embraced digital convenience, allowing you to retrieve your NOA within minutes. By logging into the IRAS myTax Portal using your Singpass, you can navigate to the ‘Notices/Letters’ section, select the relevant Year of Assessment, and instantly download or view your NOA. The system stores records from the past four years, ensuring easy access for most financial or administrative needs.
Reading Your NOA
Understanding the components of your NOA is crucial. The document starts by listing your Year of Assessment, which refers to the income earned in the previous calendar year. It then outlines income from various sources employment, business, or property rental. Next, deductions and reliefs such as CPF contributions or dependant support are subtracted to calculate your chargeable income. Finally, the tax payable, including any applicable penalties or rebates, is detailed clearly. Knowing how to interpret this breakdown helps ensure tax accuracy and clarity.
Never Miss an Update, Set Up Alerts for Your NOA
To keep your tax affairs in order, it’s advisable to enable notifications through the myTax Portal. By updating your contact details and opting in for SMS or email alerts, you’ll receive timely reminders when new notices like your NOA are issued. This helps you stay informed, especially during tax season, and reduces the risk of missing crucial deadlines.
Need Older NOAs? Here’s How to Retrieve Them
While the myTax Portal offers access to NOAs from the past four years, you can still retrieve older records if needed. To do this, visit the IRAS Document Request page and specify your document type. Requests can be submitted via live chat or email. Keep in mind that retrieving documents older than four years may involve an administrative fee.
When and Where Your NOA is Most Commonly Required
Knowing when you might need your NOA can prepare you for smoother administrative processes. Whether you’re applying for a home loan, seeking permanent residency, enrolling your children in school, or applying for government schemes like CHAS or Workfare, the NOA serves as a trusted record of your income. It’s often used in private rental agreements, insurance assessments, and even educational grant applications, making it a versatile document in everyday Singaporean life.
