What does the Thai Revenue Department usually examine in a tax audit, and how should we respond to a notice?
The Revenue Department most often examines input VAT, missed withholding tax, deductibility of expenses and related-party transactions. VAT refund claims, long-running losses and inconsistent filings are common triggers. On receiving a notice, appoint one contact, provide documents within the requested scope and keep written records; if you disagree with an assessment, you can appeal within the set period.
