What to Expect During a Tax Audit and How to Prepare for It

A tax audit can be an intimidating experience for any business — even those with nothing to hide. Whether you operate in Singapore under IRAS or in Malaysia under LHDN, a tax audit is a formal review of your company’s tax returns and financial records to ensure accuracy and compliance.

In this article, we break down what happens during a tax audit, why you might be selected, and how to prepare effectively to minimise stress, disruption, and potential penalties.

Why Do Tax Authorities Conduct Audits?

Tax authorities like IRAS and LHDN conduct audits to:

Detect underreported income, overstated deductions, or non-compliance
Monitor high-risk industries or cash-heavy businesses
Verify information discrepancies between returns and third-party sources
Educate taxpayers and improve voluntary compliance

Being selected does not always mean you’ve done something wrong, but how you respond matters greatly.

Common Triggers for a Tax Audit

Inconsistent or unusual financial ratios
Significant fluctuations in reported income or expenses
Late filings or amended returns
Frequent losses despite ongoing operations
High-value or suspicious transactions
Third-party complaints or whistleblower reports

What Happens During a Tax Audit?

Here’s a step-by-step breakdown of the typical process:

1. Notification Letter

You will receive a formal notice from the tax authority outlining the scope, period, and purpose of the audit. This may include a request for specific records.

2. Document Submission

You’ll be required to submit:

Tax returns (e.g. Form C, Form EA, GST returns)
Financial statements
General ledger and trial balance
Bank statements and reconciliations
Invoices, receipts, contracts, and payroll records

3. Review by Tax Officers

Tax officers will review your records for discrepancies, red flags, and compliance gaps. This may involve correspondence or physical visits to your office.

4. Interview or Field Audit (if applicable)

In some cases, auditors may conduct on-site interviews with key personnel or inspect your business premises, especially if records raise concerns.

5. Preliminary Findings and Clarifications

You’ll receive a draft audit report or clarification request. You may be asked to justify certain transactions, provide missing documents, or explain accounting treatments.

6. Final Assessment

After reviewing all inputs, the authority will issue an audit conclusion. If discrepancies are found, penalties, interest, or back taxes may apply.

How to Prepare for a Tax Audit

1. Maintain Complete and Organised Records

Keep all supporting documents, including receipts, contracts, and approval emails, neatly filed (digitally or physically) for at least 5 to 7 years, as required by law.

2. Perform Internal Reviews

Conduct periodic reviews of your financials and tax filings to catch errors early. This is especially important for companies with complex structures or high transaction volumes.

3. Reconcile Your Books

Ensure your accounting records align with tax filings. Discrepancies between your ledger and your tax return are common audit triggers.

4. Be Transparent and Cooperative

If selected for an audit, respond promptly and honestly. Being cooperative often results in a smoother process and can reduce penalties.

5. Seek Professional Assistance

Engage your accountant or a tax advisor early. A qualified professional can help you interpret queries, prepare explanations, and deal directly with the auditors.

Tips to Avoid Future Tax Audits

File your taxes accurately and on time
Avoid claiming questionable deductions
Disclose all income sources, including foreign income
Use reputable software or accounting systems
Stay informed about tax updates and legislative changes

Consequences of Poor Audit Preparation

Being unprepared for a tax audit can lead to:

Penalties and backdated tax payments
Prolonged investigations
Business disruption
Reputation risk with banks and investors
Possible legal action in severe cases
