Precision and Integrity in Thai Tax Advisory
Chai Compass was founded to fill a specific gap: quality, English-language tax advisory for the international community operating in Thailand, backed by genuine depth in Thai revenue law.
Back to HomeA Firm Built for Thailand's Evolving Tax Landscape
Chai Compass was established in Bangkok in 2007 by a team of Thai-qualified CPAs and tax advisors who had spent their careers navigating the complexities of the Revenue Code on behalf of multinational clients and growing Thai enterprises. What began as a boutique advisory practice has grown steadily through referrals from satisfied clients — a testament to the quality of work delivered over nearly two decades.
The name reflects our purpose: to act as a compass for individuals and businesses working through Thailand's tax obligations. We don't aim to be the largest firm in Sathorn. We aim to be the most thoughtful one — the practice that clients trust when the question genuinely matters.
From our offices on Sathorn Nua Road, we serve a diverse clientele that includes expatriate professionals, foreign-invested companies, Thai family-owned businesses, regional holding structures, and startups navigating their early compliance obligations. Each engagement receives the direct attention of a senior advisor — not a junior team working to a template.
Our approach is grounded in the Revenue Code, its implementing regulations, and decades of practical experience with Revenue Department processes. We write clearly, document our reasoning carefully, and make sure our clients understand both the analysis and the alternatives before any decision is made.
Our Mission
To provide carefully considered, well-documented tax advisory that gives clients the information they need to make confident, legally sound decisions in Thailand.
Our Values
- Accuracy above assurance — we tell clients what the law says, not what they'd prefer to hear.
- Written documentation — every position is referenced, every recommendation is recorded.
- Proportionate advice — we calibrate our recommendations to the actual risk and value at stake.
- Long-term relationships — most of our work comes from clients who return year after year.

How We Work
Every engagement at Chai Compass follows a defined quality framework. These protocols shape how we gather facts, document our analysis, and communicate recommendations.
Revenue Code Verification
All advice is cross-checked against the current Revenue Code, relevant Revenue Department circulars, and published interpretations before being delivered to a client. We do not rely on memory or general principles alone.
Written Position Papers
Corporate and audit engagements conclude with a written position paper that records the facts considered, the legal basis applied, and the alternatives assessed. Verbal-only engagements are not our practice.
Client Confidentiality
All client information is held in strict confidence under professional advisory obligations. Documents shared with us are used solely for the purposes of your engagement and are not disclosed to third parties.
Continuing Professional Development
Our advisors undertake structured continuing education through the Thai Institute of CPAs and revenue law seminars. Regulatory updates are reviewed internally and shared with affected clients on a proactive basis.
Conflict Screening
Before each engagement, we screen for conflicts of interest. Where any concern exists, we disclose it to the prospective client before proceeding. Our independence from any particular industry or business group is a deliberate feature of our practice.
Secure Document Handling
Tax documents contain sensitive financial data. We maintain secure file management practices for both physical and digital materials, with access controls restricting document visibility to the assigned engagement team only.
Tax Advisory Grounded in Thai Revenue Law
The Thai Revenue Code presents particular complexity for foreign nationals and international businesses: sourced-income rules, withholding obligations on cross-border payments, BOI compliance conditions, transfer pricing requirements, and the interaction between domestic law and Thailand's extensive network of double taxation agreements all demand careful navigation.
Chai Compass maintains focused expertise across the major tax types administered by the Revenue Department: personal income tax, corporate income tax, value added tax, specific business tax, and withholding tax. For each type, we maintain working familiarity with the applicable regulations, administrative practice, and current enforcement priorities.
Our location in the Sathorn financial district reflects our client base: international companies with Bangkok offices, expatriate executives, and Thai enterprises with cross-border activities. We offer all advisory services in both English and Thai, and conduct Revenue Department correspondence entirely in Thai to ensure no communication barrier in official proceedings.
