Case Study: Surviving a Professional Services Audit
In 2025, a European consulting firm based in Bangkok received an audit notice. The trigger? A large input VAT refund claim and high travel expenses. Their journey offers a masterclass in audit survival.
The Scrutiny
The Revenue Department requested a review of the last 2 years of filings. They focused specifically on "Director's Business Trip" expenses, which included luxury hotel stays and international flights.
The Defense Strategy
Instead of resisting, the firm provided a structured data package:
- Board Resolutions: Approving the business travel for specific overseas client acquisition.
- Outcome Reports: Showing that the travel led to new contracts for the Thai entity.
- Digital Ledger: Linking every receipt to a specific project code.
The Result
Because every expense had a clear Business Purpose, the auditor allowed 95% of the claims. The firm only had to pay a small adjustment for some "entertainment" costs that were missing attendee lists.
Crucial Lesson
The auditor isn't looking for perfection; they are looking for substance. If an expense is truly for generating revenue in Thailand, and you can prove it with more than just a receipt, your audit risk decreases significantly.
