Thaksin Sues Revenue Department Over Alleged Double Taxation

De facto Pheu Thai boss Thaksin Shinawatra has instructed his lawyer to file a lawsuit against the Revenue Department, alleging "double taxation" in its move to seize additional assets. The lawsuit stems from the tax dispute over the proceeds from the 2006 sale of Shin Corporation shares. Thaksin's lawyer, Mr. Winyat Chatmontri, suggested that the Revenue Department should instead seek the funds from the Finance Ministry. The Central Tax Court has scheduled a hearing on a request for an injunction (temporary protection) for Oct. 7. The Revenue Department is currently proceeding to seize and freeze Thaksin’s assets to settle a tax debt arising from the 2006 sale of Shin Corp shares to Temasek Group. This action follows the Supreme Court’s Tax Division ruling on Aug. 14, 2025, that the Revenue Department’s tax assessment was lawful. Winyat stated that Thaksin has no intention of disputing or disrespecting the final judgment. However, he emphasized that while the Supreme Court ruled the assessment on 329,200,000 Shin Corp shares sold to Temasek Group in 2006 (valued at 15,883,900,000 baht) was lawful and that Thaksin was liable for tax on said income, this amount constituted only a portion of the total proceeds Thaksin received from selling his Shin Corp shares (totaling 1,419,490,150 shares). Furthermore, the Supreme Court’s Criminal Division for Persons Holding Political Positions had already ruled on Feb. 26, 2010, that the entire proceeds (totaling 46,373,687,454.70 baht) must be forfeited to the state. Consequently, there remained no income or other benefit derived from the Shin Corp share sale upon which Thaksin was liable to pay tax for the year 2006, according to the lawyer. Therefore, the subsequent seizure and attachment of Thaksin’s assets constituted a redundant action, duplicating the enforcement of the judgment rendered by the Supreme Court’s Criminal Division for Persons Holding Political Positions, he said.
