Why Chai Compass

Considered Expertise, Clearly Communicated

Thai Revenue Code Depth

Our advisors hold CPA and Thai Tax Consultant (TA) qualifications. We stay current with Revenue Department circulars and regulatory amendments on a continuous basis.

Bilingual Representation

All correspondence and meetings with the Revenue Department are handled in Thai, while client deliverables are prepared in clear, accessible English.

Documented Positions

Every recommendation is backed by written position papers with statutory references — not verbal opinions. You receive a clear, referenced record of all advice provided.

Expatriate Familiarity

We work regularly with foreign nationals and international companies operating in Thailand. Cross-border income, DTA applications, and work permit implications are part of our everyday practice.

Careful, Measured Advice

We offer considered analysis within the bounds of applicable law. Our guidance reflects regulatory reality rather than overpromising outcomes that cannot be responsibly assured.

Sathorn Location

Located on Sathorn Nua Road in Bangkok's financial district, our office is accessible from BTS Chong Nonsi and the expressway — convenient for in-person consultations.

Common Questions

Frequently Asked Questions

Do I need to file a Thai personal income tax return as a foreigner?

If you reside in Thailand for 180 days or more in a tax year and receive income sourced from — or remitted into — Thailand, you generally have filing obligations under the Revenue Code. The specifics vary based on your residency status, employment type, and applicable double taxation agreements. Our advisory process begins with a residency and income assessment to clarify exactly where you stand.

What is the process for the Corporate Tax Structuring service?

The engagement begins with a fact-gathering session covering your business model, transaction flows, entity structure, and existing filings. We then prepare a position paper that maps the applicable tax types, identifies structuring considerations, and models alternative scenarios. Deliverables include written documentation of every recommendation made, along with statutory references.

The Revenue Department has contacted us for an audit. What should we do first?

Avoid making any uncoordinated responses to the Revenue Department before seeking advice. The initial assessment letter typically sets a response deadline — these deadlines are important. Contact us as early as possible so we can review the scope of the inquiry, help you organise supporting documentation, and prepare a coordinated response. Early engagement generally leads to better outcomes than last-minute preparation.

How does Thai double taxation treaty relief work for foreign income?

Thailand has concluded double taxation agreements with over 60 countries. Whether treaty relief applies depends on which country is involved, the type of income, and your residency classification. For some income types, the treaty may reduce or eliminate Thai tax; for others, the domestic rate applies in full. We assess treaty applicability as part of our personal income tax advisory and clearly document any positions taken.

Can BOI-promoted companies still have VAT and withholding tax obligations?

Yes. BOI corporate income tax exemptions do not affect VAT, specific business tax, or withholding tax obligations. Many companies with BOI privileges focus on the CIT exemption and inadvertently underprepare for these other tax types. Our corporate structuring advisory addresses the full tax picture, not just the headline incentive.

What are your typical engagement timelines?

Personal income tax advisory typically concludes within 5–7 working days of receiving all relevant documents. Corporate structuring engagements generally run 3–5 weeks depending on transaction complexity. Audit support timelines are determined by Revenue Department schedules, though we begin document review and representation preparation within 2 working days of instruction.
