Annual financial statements guide
Annual financial statements and filing in Thailand
A practical sequence for closing the books, preparing the statement pack, coordinating audit questions and retaining accepted filing evidence.
Quick answer
Start from the company’s registered accounting period and closed ledger. Prepare supporting schedules, coordinate the applicable audit work, complete company approval and DBD e-Filing, and connect the final numbers to PND 50.
General information only. Entity-specific audit, approval and filing requirements must be confirmed against current official guidance and the company facts.
