Annual Audit in Thailand: What Every Company Must File

Thailand requires every registered company to have its financial statements audited by a licensed Thai auditor and filed annually — regardless of size, activity, or whether the company traded at all.

What must be filed

• Audited financial statements signed by a licensed Thai CPA
• The annual corporate tax return (PND50), within 150 days of the financial year-end
• Filing with both the DBD and the Revenue Department

Even if dormant?

Yes — a dormant company with no revenue still must file an audited statement. Missing it leads to penalties and can complicate future filings.
