As a trusted corporate services provider in Singapore, we understand that getting a notice of an audit from the Inland Revenue Authority of Singapore (IRAS) is stressful news to any businessperson or entrepreneur. Many clients approach us asking, “Why is my business being audited?” or “How do I avoid this in the future?” The fact is, IRAS audits occur more often than people think, and they’re not always a result of wrongdoing. Throughout this article, we will help you understand what usually causes an IRAS audit, the process of how it is conducted, and how our tax advisory services within Entrust can guide you in being compliant and ready.”

What Is an IRAS Audit?

An IRAS audit is a formal investigation by the Inland Revenue Authority of Singapore to ensure businesses and individuals get their income right and pay the right amount of tax. It may be a checking of financial statements, tax declarations, bank accounts, and other papers.

There are two types of audits in Singapore:

  • General tax audits which are designed to meet existing tax laws.
  • Investigation audits, more serious and potentially involving suspicion of tax evasion.

Whatever the type, being selected for an audit does not necessarily equate with you doing something wrong. But having knowledge about what triggers these audits can leave you on the safe side of business tax adherence.

Common Triggers for an IRAS Audit

Accountant reviewing financial documents and tax returns to identify common IRAS audit triggers.While IRAS doesn’t publish an official list of audit triggers, based on our experience in tax audit cases, we’ve identified some key red flags:

1. Inconsistencies in Tax Returns

Year-to-year variations in reported expenses and income, or out-of-balance amounts between financial statements and GST returns, have a tendency to flag as differences. Even small data entry errors can lead to further review.

2. Significant Deductions or Losses

Running unusually large business expenses, capital allowances, or suffering huge losses within three years can encourage IRAS to verify if such claims are genuine.

3. Suspicious Transactions or Cash Transactions

Businesses dealing heavily in cash or engaging in irregular financial transactions, especially those without clear documentation are more likely to attract attention.

4. Delays in or Incomplete Submissions

Persistent failure to file tax returns, poor records, or refusal to respond to IRAS information requests can lead to an audit.

5. Industry-Specific Risks

Certain sectors such as F&B, construction, or retail businesses will be more prone to interrogation due to their cash nature or typical fluctuations in reported income.

At Entrust, our tax advisory services help clients maintain clean and consistent financial records to prevent these usual catalysts for audits.
