Tax Litigation in Thailand

Similar to other types of corporate disputes, tax-related conflicts often begin with an earnest attempt to resolve matters outside the courtroom.

Tilleke & Gibbins’ latest update to Tax Litigation in Thailand provides an outline for navigating tax-related disputes within the Thai legal framework. It aims to equip readers with a fundamental understanding of procedures and practices within the Thai tax litigation landscape.

Thailand’s Ministry of Finance has introduced a five-year personal income tax exemption on capital gains from the disposal of cryptocurrency or digital tokens. The Ministerial Regulation No. 399, published in the Government Gazette on September 5, 2025, offers the personal income tax exemption for transfers occurring between January 1, 2025, and December 31, 2029. The ministerial regulation was enacted to promote Thailand as a global financial center and digital asset business hub while encouraging increased domestic investment in digital assets. Key Conditions The exemption, which covers capital gains from cryptocurrency and digital token disposals during the specified five-year period, applies only to individuals. Companies that trade in digital assets are not eligible for this tax exemption. With the tax holiday set to expire in 2029 (unless extended), individual traders should plan ahead for postexemption taxation to ensure full compliance with Thailand’s personal income tax requirements. Proper documentation of digital asset transactions during the exemption period will be essential for future tax compliance. For more details on this tax exemption, or on any aspect of Thailand’s tax law and regulations, please contact Saravut Krailadsiri at [email protected] or Papavarin Sarawongsuth at [email protected].

Under Thai law, authorized directors stand as a company’s mind and will and, as such, may incur personal criminal liability for acts or omissions committed in the course of company business. When allegations surface, directors must be prepared for the practical reality that, before guilt or innocence is ever adjudicated, they could be deprived of liberty unless bail release is promptly achieved through the competent legal authority. When Bail Can Be Granted Two procedural moments trigger the need to consider bail. The first arises during the investigative phase, when a claim is lodged against a director with the competent law enforcement authorities. Upon receipt of a complaint, the assigned inquiry officer summons the director for questioning, compiles evidence, and ultimately forwards a prosecution or nonprosecution recommendation to the public prosecutor. Although the public prosecutor retains ultimate discretion to indict an accused director, the police or prosecutor may conclude that pretrial detention is necessary and may therefore apply to the court for an order to hold the director in court custody. The second moment occurs after a criminal case is filed directly with the court. This occurs once a court accepts a criminal case filed by a prosecutor against a director or, alternatively, when the court accepts a case filed by an individual for trial. For cases filed by individuals, the plaintiff presents prima facie evidence at the preliminary hearing, and the court will accept the complaint if it finds sufficient grounds, thereby conferring upon the director the status of a criminal defendant. Upon acceptance of the criminal case, the court then has the inherent authority to order custody pending trial unless the defendant secures bail release. Procedural Considerations Experienced litigants typically prepare bail security in advance and submit a bail petition at the earliest possible time. While there are
