What does an NOA contain? 

A Notice of Assessment (NOA) is an official document sent by the tax authority in Singapore, the Inland Revenue Authority of Singapore (IRAS), to individuals and businesses to inform them of the assessment of their income tax liability.

The NOA contains detailed information about the taxpayer’s income and tax liability for the specific assessment year.

The NOA includes the following important details:

  • Income Particulars: It provides a summary of the taxpayer’s income sources, such as employment income, rental income, investment income, and other taxable income.
  • Tax Assessment: The NOA specifies the amount of tax owed or the refundable amount. It calculates the tax payable based on the taxpayer’s income, deductions, reliefs, and applicable tax rates.
  • Income Statement: The NOA shows a breakdown of the taxpayer’s income and deductions used in the tax assessment, giving a clear understanding of how the final tax liability is determined.
  • Payment Details: If there is an outstanding balance, the NOA provides information on how and when to make the tax payment.

When do I receive an NOA? 

Taxpayers usually receive their NOAs after filing their income tax returns.

The tax filing process typically starts in March each year for the previous year’s income.

Upon completing the filing process, taxpayers can expect to receive their NOAs within a few weeks.

The IRAS offers various channels to receive the NOA:

  • Online Portal: Taxpayers can log in to myTax Portal, the IRAS’ e-services platform, to obtain a digital copy of their NOA.
  • Mail: The IRAS sends a physical copy of the NOA to the taxpayer’s registered address. This allows taxpayers to keep a hard copy for their records.

It is important to note that the NOA is an official confirmation of the tax assessment and should be retained for future reference and audits.

What if I don’t receive an NOA? 

If you have filed your income tax return but have not received your NOA within four weeks, it is essential to take the following steps:

  1. Check the IRAS Online Portal: Log in to myTax Portal and verify if the NOA is available for download. Sometimes, technical issues or delays in mail delivery can occur, and the digital copy may be accessible before the physical copy arrives.
  2. Contact the IRAS: If you cannot access the NOA online or have not received it by mail, contact the IRAS through their hotline or email. They will assist you in resolving any issues and provide information on the status of your NOA.

It is crucial to follow up on the NOA as it confirms the outcome of your income tax assessment, including any payable tax amount or refundable balance.

Notice of Assessment Singapore Conclusion

In conclusion, the Notice of Assessment (NOA) is a crucial document for businesses in Singapore.

It provides important information about the company’s tax obligations and serves as proof of their compliance with tax regulations.

By understanding the key points related to the NOA, businesses can ensure smooth operations and avoid any potential penalties or issues in the future.

One of the essential aspects to note is the remittance information provided in the NOA.

This information allows businesses to accurately track their tax payments and ensure that they are being allocated correctly.

Companies must review this information carefully and report any discrepancies or concerns to the tax authorities promptly.

Another important point is that the NOA includes the company’s tax liability for a specific year, such as 2023.

Businesses should make it a priority to pay the indicated amount within 30 days of receiving the NOA to avoid any late payment penalties.

By staying up-to-date with their tax liabilities, businesses can maintain compliance and avoid unnecessary complications.

Additionally, businesses should retain a copy of their tax documents, including the NOA, for future reference and audit requirements.

These documents serve as evidence of their compliance and are essential for any tax-related inquiries or investigations.

Companies should keep these documents in a secure location and ensure that they are easily accessible when needed.

It eliminates the need for physical copies and reduces administrative hassle for businesses.

However, if businesses prefer physical copies of their NOAs, they can request them from the IRAS.

It is important to note that there may be search fees associated with obtaining physical copies, and these fees should be taken into account when budgeting for administrative expenses.

From 2023 onwards, the IRAS will cease the practice of mailing physical copies of the NOA.

This digital transformation aims to streamline processes, reduce paper usage, and enhance efficiency.

Businesses should be prepared to adapt to this change and embrace online platforms for accessing and managing their NOAs.
