As the annual audit season returns, how should Thai companies interpret their audit reports?

Introduction: Auditing is not only about compliance but also serves as a health check for enterprises.

From April to June each year marks the annual audit season for Thai companies. Whether a local Thai company or a foreign-invested enterprise (including those holding BOI certificates), all must complete an independent audit in accordance with the law and submit financial statements and tax filings within prescribed deadlines. However, when confronted with highly technical audit reports, many managers and investors often find themselves puzzled:

• “How should one read an audit report?”

• “Which areas should be the primary focus?”

• “Is an audit equally important for small companies?”

• “Do BOI-registered companies have additional requirements?”

Today, TMA Group will provide you with a professional analysis of key points in Thai audit reports to help enterprises navigate the audit season smoothly, enhance management practices, and mitigate risks.

I. Basic Requirements for Annual Audits of Thai Companies

Thai law stipulates:

All registered companies, regardless of size, must engage a certified public accountant (CPA) to perform an independent audit at the end of each fiscal year (some small enterprises may opt for a simplified audit, but engaging a CPA is recommended for greater assurance).

Upon completion of the audit, the company is required to:

1. Approve the financial statements at the Annual General Meeting (AGM).

2. Submit the audited financial statements to the Department of Business Development (DBD).

3. File the annual tax return (PND50) with the Revenue Department.

4. For enterprises benefiting from BOI investment incentives, submit an additional project execution report and financial summary to the BOI.

II. Standard Structure of Thai Audit Reports

A standard audit report typically includes:

III. Key Points in Interpreting Audit Reports

1. Types of Audit Opinions

• Unqualified Opinion: The financial statements are fair and accurate (ideal outcome).

• Qualified Opinion: There are some issues that require attention to specific matters.

• Adverse Opinion: Significant issues rendering the overall statements misleading.

• Disclaimer of Opinion: Audit scope was restricted, and no opinion could be expressed.

Note: If the report is not an Unqualified Opinion, promptly identify the underlying reasons and assess their impact on tax, financing, BOI compliance, and other areas.

2. Analysis of Core Financial Statements

• Balance Sheet (BS): Focus on the reasonableness of cash balances, accounts receivable, inventory, and short-term and long-term liabilities.

• Profit and Loss Statement (PL): Monitor trends in revenue and costs, the stability of gross margin, and net profit levels.

• Cash Flow Statement (CF): Verify whether operating cash flow is positive and whether cash flows from investing and financing activities are reasonable.

Note: Healthy cash flow reflects a company’s true operating condition more accurately than simple profitability.

3. Importance of Notes to Financial Statements

Notes typically include:

• Loans, mortgages, and guarantees

• Details of related-party transactions

• Tax disputes and contingencies

• Changes in accounting estimates or asset impairments

Note: Audit notes often conceal critical indicators of operational risk and must be read carefully.

IV. Audit Practices for Small Enterprises

In Thailand, even small enterprises are required by law to complete an annual audit. Typically, small enterprises choose based on their circumstances:

• Engaging a certified public accountant (CPA) or a small audit firm for the annual audit

• Companies with high transaction volumes or those involved in BOI incentives or export tax rebates are advised to commission a professional audit team

Note: An audit is not merely a filing but a cornerstone of compliance, financing credibility, and risk management; choosing a professional and appropriate audit firm is more important than simply minimizing cost.

V. Special Considerations for BOI-Registered Companies

For companies holding BOI investment promotion certificates, in addition to submitting annual audit reports to the DBD and the Revenue Department, they must also submit a project progress report and an audited financial summary to the BOI.

The main contents include:

• Investment amount and progress

• Number of employees and proportion of local staff

• Sales revenue and export ratio

• Equipment investment and raw material import utilization

Submission Requirements:

• Submission via the BOI electronic systems (e-Submission or IC System)

• Completion within 150 days after the fiscal year-end (typically by the end of May of the following year)

Note: Underreporting or misreporting BOI project data may result in suspension or revocation of BOI incentives, affecting significant benefits such as customs duty exemptions and corporate income tax waivers.
