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. The prospect of engaging in tax litigation can be daunting, given the potential strain on commercial relationships, the legal expenses, and the uncertainty surrounding its resolution. However, there are instances when tax litigation becomes the sole avenue for seeking redress.

For individuals and entities contemplating the pursuit of tax-related legal remedies, the Thai legal system offers an accessible, impartial, and equitable platform for dispute resolution. 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.

Following the enactment of the Tax Administration Law (TAL), Myanmar’s Ministry of Planning and Finance has issued Notification No. 44/2024, which outlines directives and procedures for addressing violations of tax law provisions. These procedures, which came into force on June 13, 2024, primarily focus on three key areas: tax evasion, impeding tax administration, and failure to preserve secrecy. The notification primarily aims to address tax evasion, impeding tax administration, and failure to preserve secrecy, classifying these offenses as either subject to arrest without warrant or not. Notably, tax evasion is classified as an offense subject to arrest without warrant, while impeding tax administration and failure to preserve secrecy are not. The notification also prescribed the forms for notifying taxpayers before taking any action. Tax Evasion Tax evasion refers to a taxpayer who willfully evades the assessment, payment, or collection of tax. Penalties for such offenses include fines of MMK 250,000 (approx. USD 120) or 100% of the evaded tax (whichever is greater), imprisonment for up to seven years, or both. The enforcement process for tax evasion requires the chief officer of the township revenue department or an officer in charge (the tax authority) to assess the relevant documents and information provided by the taxpayer. If a taxpayer is found to be evading tax, the tax authority must send a notice in the prescribed form for verification within 15 days. Taxpayers may apply for a one-time extension of 15 days to submit requested documents and make disclosures. If the taxpayer cannot fulfill the requirements as instructed, the tax authority will seek approval from the director general of the Internal Revenue Department (IRD) for criminal proceedings as cognizable offences. Impeding Tax Administration and Failure to Preserve Secrecy Impeding tax administration refers to obstruction or attempted obstruction of taxation staff or officers

Thailand has continued to face economic challenges since the COVID-19 pandemic, and some businesses have struggled to survive. One of most important measures that indebted businesses in Thailand can take is to file a business rehabilitation petition with the Bankruptcy Court. The Bankruptcy Act B.E. 2483 (1940) provides “automatic stay” measures to protect the debtors that have entered the business rehabilitation process, and during this time creditors have duties and rights under the Bankruptcy Act as well. Once Thailand’s Bankruptcy Court accepts a rehabilitation petition and issues an order for rehabilitation, the debtor is under this automatic stay protection against actions from the creditor to seek debt repayments, and the creditors are only allowed to pursue their debt repayments by submitting a debt repayment application to the official receiver within one month of publication of the plan preparer’s appointment in the Government Gazette. These are general conditions specified in the Bankruptcy Act. However, there are several practical precautions that are not specified in the Bankruptcy Act but that creditors should take during rehabilitation. Below are several steps creditors need to consider taking at various stages of the rehabilitation process. 1. Appointing a local Thai representative to act on behalf of the creditor in the rehabilitation The rehabilitation process requires much more than just submitting the debt repayment application within the fixed one-month period and then waiting for the result. It also involves contacting, meeting, and discussing with the official receiver, plan preparer, other creditors, or debtor representative to investigate or settle any arguments on the debt. Moreover, the language used in all the processes and documents is usually Thai. In practice, creditors—especially foreign creditors—should authorize a Thai attorney or representative through a valid power of attorney (POA) to represent them during all the rehabilitation proceedings. This includes the investigative
