Thai ex-PM ordered to pay 17.6 billion baht tax debt on Shin Corp share sale; his estimated 72.5 billion baht overseas fortune deemed sufficient to cover the historical fine.
The financial holdings of Thailand’s former Prime Minister, Thaksin Shinawatra, have come under intense scrutiny following a landmark ruling by the Supreme Court that ordered him to settle a long-disputed tax debt totalling 17.6 billion baht (approximately US$ 486 million).
The judgement, delivered on 17 November 2025 in the "Shin Corp Share Tax" case, sent fresh tremors through the political and business communities.
The Supreme Court reversed the decisions of the lower courts, ruling that the Revenue Department’s assessment on the 17.6 billion baht share sale was lawful.
This final judicial confirmation means the former leader must pay the tax, plus penalties and surcharges.
The decision immediately raised questions over the stability of Thaksin’s financial empire and whether his accumulated wealth—much of it held offshore—would be sufficient to cover the enormous liability.
Thaksin's Global Billion-Baht Fortune
Despite having a substantial portion of his domestic assets seized by court order in 2010 (46 billion baht) and not filing an asset declaration since leaving office, Thaksin Shinawatra has consistently been ranked as a global billionaire by Forbes magazine.
The latest Forbes ranking for 2025 estimates his total net worth at approximately US$ 2.1 billion, equivalent to around 72.5 billion baht at prevailing exchange rates.
Thaksin’s wealth has shown a steady upward trend over the last decade, rising from US$ 1.7 billion in 2013, a growth primarily attributed to investments and business activities conducted outside Thailand.
The remaining source of the former PM's immense wealth—which largely escaped previous asset seizures—is believed to be secured in international investments and high-value real estate.
These assets reportedly include:
Overseas Investments: Holdings in health technology start-ups in the United Kingdom, alongside investments in gold and diamond mining operations and other ventures across South Africa.
Real Estate: High-value property, including a home in London valued at approximately 264 million baht, and a luxury villa in the prestigious Emirates Hills district of Dubai, which served as a primary residence during his time abroad.
Family Holdings: Assets managed by members of the Shinawatra family, including his daughter, Paetongtarn Shinawatra, who is a significant figure in her own right.
Capacity to Settle the Debt
While the 17.6 billion baht tax bill represents a considerable financial obligation, it accounts for approximately 24% of Thaksin’s total estimated 72.5 billion baht wealth.
Given the sheer scale of his multi-billion-baht net worth and the nature of his fluid, overseas assets that can be converted into cash, analysts believe that Thaksin possesses the financial capability to secure the necessary funds and settle the tax liability as ordered by the Supreme Court.
The ruling marks the end of a tax dispute that has spanned almost two decades.
The Revenue Department must now proceed with the legal mechanisms necessary to collect the massive sum, reinforcing the former Prime Minister's ultimate responsibility for the tax on the share sale.
