Former prime minister Thaksin Shinawatra has filed a case with the Central Tax Court challenging the Revenue Department's efforts to seize and freeze assets over tax linked to his 2006 sale of Shin Corp shares.
His lawyer, Winyat Chatmontri, said on 16 September that Thaksin is not challenging or disrespecting the final Supreme Court ruling on the tax assessment. Instead, he argues that the department is attempting to collect twice from money already forfeited to the state.
The Central Tax Court has accepted the case and will hear Thaksin's request for temporary protection on 7 October 2026. A hearing to identify the issues in dispute and take evidence is scheduled for 16 November 2026.
Dispute centres on Shin Corp sale proceeds
The Supreme Court's Tax Division ruled on 14 August 2025, in case number 68902568, that the Revenue Department's tax assessment was lawful.
The ruling concerned income of 15.8839 billion baht from Thaksin's sale of 329.2 million Shin Corp shares to Singapore's Temasek group in 2006. The court found that the sum was assessable income and had to be included in his tax calculation for that year.
Winyat said that amount formed part of Thaksin's wider sale of 1,419,490,150 Shin Corp shares. He said the full proceeds, totalling 46,373,687,454.70 baht, had already been ordered forfeited to the state by the Supreme Court's Criminal Division for Holders of Political Positions on 26 February 2010, in case Am.1/2553.
According to the lawyer, Thaksin therefore retained no income or other benefit from the transaction on which further 2006 tax could be charged.
Lawyer seeks halt to further enforcement
Winyat said subsequent asset seizures and freezes were duplicative of enforcement under the 2010 forfeiture ruling, and exceeded Thaksin's legal liability. The tax case was filed on 2 July 2026.
Thaksin has also asked the court to order the Revenue Department to stop further seizures or freezes until a final ruling is issued. The request is made under Section 254(2) of the Civil Procedure Code and Section 17 of the Act on the Establishment of and Procedure for Tax Courts, BE 2528.
The Revenue Department had previously said it was seeking assets and could pursue bankruptcy proceedings if it could not recover the full tax debt. Winyat said it should instead seek the disputed tax money from the Finance Ministry, rather than take more of Thaksin's assets.
