Individual Audits by IRAS

Audits involve reviewing your income generating activities to ensure that the information in the tax return provided to us is accurate. The audits are conducted to assess the likelihood of risk. Being selected for an audit does not necessarily mean that you have made a mistake.

Purposes of Audit

These are the purposes of IRAS's tax audit programme:

  1. Ensure your business' tax returns are in compliance with the tax law;
  2. Educate your business on your tax obligations and how to comply; and
  3. Identify tax laws, policies and processes where we can simplify or clarify. 

What to Expect During an Audit

Audits are conducted by examining your accounting books, records and financial affairs to verify that income tax returns submitted are in compliance with tax laws.

Notification of Audit

We will inform your business of the audit by letter, email or telephone call. IRAS will provide the details such as the timing of the audit, and the documents/books that IRAS will examine, and the Years of Assessment to be audited primarily.  

Field Visits by IRAS Officers

Usually, the field visit is conducted by a team of three to four tax officers who carry authority cards issued by IRAS. If you need confirmation on the identity of the officer, please call IRAS at 6351 2044 or 6351 2046.

  3. Bank statements of business bank accounts and personal bank accounts, if required; and
  4. Any other records of transactions connected with your business.

Usually, the examination of accounting books and records would be conducted by a team of 2 to 4 tax auditors.  Some of your accounting records and books might be retained by auditors for further review.

3. Length of Field Visits

The length depends on your business' standard of record keeping, the degree of compliance, the scope of the audit and your level of co-operation.  The process may last from a few hours to a day.

4. Re-Visits

In the event that the requested information or records are incomplete or unavailable, the auditors might re-visit the business premises on another arranged date.

5. Information from Third Parties

In conducting further review, we may seek confirmation or obtain information from third parties. In the absence of sufficient records, we will refer to available sources of information to best estimate the financial conditions of your business.

Expense claims or other claims, e.g. capital allowance, may be disallowed in the event of insufficient supporting documents.

Conclusion of Audits

 

Most audits are completed within 12 months. The progress of an audit depends on the standard of record keeping, the scope of audit, and the support and cooperation of the business and tax representatives.

1. Communicating and Discussion of the Findings 

We usually communicate the outcome of the audit by writing or through a meeting at IRAS. 

If any adjustment(s) is to be made to your tax assessment(s), we will explain the basis of our adjustment. Issues are discussed with a view to reaching a mutually acceptable conclusion . We will also advise on areas in which you could make improvements to better comply with the tax laws.

2. If Errors are Discovered

Should the audit conclude that errors had been committed, IRAS will issue the Notice(s) of Additional / Amended Assessment and an Offer of Composition.

The Section 95 offence in the Income Tax Act refers to an offence when the taxpayer makes an incorrect return by omitting or understating income or gives any incorrect information related to any matter affecting his own tax liability, or the liability of any other person or of a partnership. Serious cases of omission or errors may be subject to court prosecution.

Businesses that disagree to the Notices of Additional Assessments must object in writing within 30 days, stating the specific grounds of objection. Notwithstanding any objection, the tax payable must be paid within one month from the date of the Notice of Assessment.
