An IRAS audit is a review of your tax returns, financial records, and other relevant documents to ensure that you have complied with the tax laws in Singapore. 

In this blog post, we will discuss what you need to know about IRAS audits in Singapore, and how tax experts and accounting services in Singapore can help you prepare for an audit.

Why Does IRAS Conduct Audits?

IRAS conducts audits to ensure that taxpayers are complying with Singapore’s tax laws. The agency uses a risk-based approach to select taxpayers for audit, based on various factors such as the size of the business, the complexity of the tax return, and the taxpayer’s history of compliance. 

The aim of an IRAS audit is to verify the accuracy and completeness of the taxpayer’s tax returns and to detect any errors or discrepancies that may result in the underpayment of taxes.

What Triggers an IRAS Audit?

There are several factors that can trigger an IRAS audit, including:

  • A discrepancy between the income declared in the tax return and the income reported in other sources, such as bank statements, invoices, or contracts.
  • Unusual transactions, such as a sudden increase in expenses or a large cash transaction.
  • A history of non-compliance with tax laws, such as late filing of tax returns or failure to pay taxes on time.
  • A referral from another government agency, such as the Commercial Affairs Department (CAD) or the Monetary Authority of Singapore (MAS).
  • A random selection, that’s based on the risk profile of the taxpayer.


What Happens During an IRAS Audit?

During an IRAS audit, the auditor will request access to your financial records, including bank statements, invoices, contracts, and tax returns. The auditor will review these documents to ensure that they are accurate, complete, and in compliance with the tax laws in Singapore. 

The auditor may also conduct interviews with you or your employees to gather more information about your business operations.

If the auditor discovers any discrepancies or errors in your tax returns, you may be required to provide additional documentation or explanations to support your claims. The auditor may also adjust your tax assessment if they believe that you have underreported your income or overclaimed your deductions.

How Can Tax Experts and Accounting Services in Singapore Help?

Tax experts and accounting services in Singapore can help you prepare for an IRAS audit by:

  • Reviewing your tax returns and financial records to identify any potential issues that may trigger an audit.
  • Assisting you in organizing your financial records and ensuring that they are accurate and complete.
  • Advising you on the tax laws in Singapore and helping you to understand your rights and obligations as a taxpayer.
  • Representing you in discussions with the IRAS auditor and providing explanations and documentation to support your claims.
  • Helping you to appeal against any adjustments made by the IRAS auditor, if necessary.



An IRAS audit can be a daunting and stressful experience for taxpayers in Singapore. However, by being aware of the audit process and engaging the services of a tax expert or accounting service in Singapore, you can be better prepared to handle an audit and ensure that your tax returns are in compliance with the tax laws. 

Remember, it is always better to be proactive and seek professional help before an audit rather than wait until an audit is initiated. With the right preparation and support, you can successfully navigate the IRAS audit process and avoid any penalties or fines.

ACRA Cancels Registration of Filing Agent and Qualified Individual for AML/CFT Breaches

The Accounting and Corporate Regulatory Authority (ACRA) had cancelled the registrations of filing agent (RFA) and qualified individual (RQI) on 18 January 2024. The registrations were cancelled in view of breaches of anti-money laundering and countering the financing of terrorism (AML/CFT) controls under the ACRA (Filing Agents and Qualified Individuals) Regulations 2015 (the “ACRA Regulations”).

Some of the basic AMT/CFT controls that a RFA and RQI are required to exercise are as follows:

(a) perform additional customer due diligence measures when a customer is not physically present during onboarding;

(b) inquiring if there exists any beneficial owner in relation to some of its customers; and

(c) perform risk assessments i

RQIs and RFAs provide corporate secretarial services for business entities, such as helping customers to incorporate companies, file annual returns and fulfil other filing requirements under the Companies Act 1967 or other Acts under ACRA’s purview. RQIs and RFAs are required to perform customer due diligence measures in accordance with the ACRA Regulations, and conduct their business in such a manner as to guard against the facilitation of money laundering and the financing of terrorism. RQIs and RFAs must also satisfy statutory requirements such as being fit and proper persons, to be registered or continue to be registered.

RQIs and RFAs who breach their statutory obligations may be subject to enforcement actions, such as financial penalties of up to $10,000 or $25,000 per breach respectively or have their registrations with ACRA suspended or cancelled.

Therefore, RQIs and RFAs play an important role in helping to detect and combat illicit activities.
