Three Focused Advisory Services
Chai Compass concentrates on the three areas of Thai tax advisory where specialist knowledge creates the most meaningful difference for clients — personal tax, corporate structuring, and audit proceedings.
Back to HomeHow We Approach Every Engagement
Regardless of the service type, every engagement follows the same structured process. This consistency is what allows us to deliver documented, defensible advisory rather than informal opinions.
Fact Gathering
We begin with a structured review of your circumstances — documentation, prior filings, entity structure, and the specific question at hand.
Legal Analysis
We apply the relevant Revenue Code provisions, administrative directives, and treaty articles to your facts — with current references, not generalised principles.
Documentation
Our findings and recommendations are prepared in writing with statutory references, alternative scenarios where relevant, and a clear statement of the position taken.
Communication
We walk through the deliverable with you, answer questions, and confirm that the analysis is fully understood before you act on it.
Personal Income Tax Advisory
Consultation on personal tax obligations under Thailand's Revenue Code — covering residency status determination, assessable income categorisation, deduction and allowance optimisation, and withholding tax reconciliation. Applicable to both Thai nationals and expatriates with Thailand-sourced or remitted income.
The service includes preparation guidance for the PND.91 annual filing and a review of double taxation treaty applicability for foreign-sourced income where relevant.
What the Engagement Covers
Typical Timeline
5–7 working days from receipt of complete documentation.
Enquire About This ServiceCorporate Tax Structuring
Design of tax-considerate corporate structures addressing Corporate Income Tax, Value Added Tax, Specific Business Tax, and withholding tax implications of inter-company and cross-border transactions. Includes transfer pricing documentation guidance, BOI tax privilege utilisation review, and Regional Operating Headquarters (ROH) or International Headquarters (IHQ) regime assessment.
Delivered as a written position paper with alternative scenario modelling — so you can compare structural options and their tax implications before making decisions.
What the Engagement Covers
Typical Timeline
3–5 weeks depending on transaction complexity and completeness of information provided.
Revenue Department Audit Support
Representation and advisory during Revenue Department tax audits and assessments — including document preparation, examiner meeting attendance, response drafting to preliminary findings, and appeal filing where assessment results warrant challenge. Covers all major tax types.
The engagement includes penalty mitigation strategies and voluntary disclosure advisory where appropriate. Post-audit compliance recommendations are provided to strengthen future filing positions and reduce the likelihood of repeat findings.
What the Engagement Covers
Timeline
We begin document review and preparation within 2 working days of instruction. Full timelines are governed by Revenue Department schedules.
