Statutory Audit & Revenue Department Examination

Statutory financial statements must be audited and reported on by a Certified Public Accountant licensed under the Accounting Professions Act B.E. 2547. A Tax Auditor may audit and certify only small juristic partnerships meeting the criteria set by the Director-General of the Revenue Department. A dormant company is not excused: it still prepares statements, obtains an audit, files with the DBD and submits PND.50. Where the Revenue Department issues a summons under section 19 or section 23, assemble the financial statements and working papers, general ledger, input and output VAT reports, tax invoices, contracts and bank evidence. An appeal against an assessment must be lodged with the Board of Appeals within 30 days of receiving the assessment notice under section 30.
