Thai Stock Exchange Companies Contribute Nearly 40% of Corporate Tax Revenue
A study by the Stock Exchange of Thailand reveals that 861 listed companies provided 311.3 billion baht in corporate income tax in 2025, accounting for nearly 40% of the total collected by the Revenue Department.
According to a report released by the Stock Exchange of Thailand (SET) on November 9, 2026, the nation's listed companies play a critical role in supporting the government's fiscal revenue. Despite representing only 0.09% of all active legal entities in the country, the 861 companies listed on the SET contributed 311,327 million baht in corporate income tax during 2025. This figure represents 38.95% of the total corporate income tax collected by the Revenue Department for that year.
The data further highlights the long-term economic impact of these firms, noting that over the past decade (2016–2025), listed companies have paid a cumulative total of over 2.67 trillion baht in taxes. For residents and investors, this underscores the significant role the capital market plays in the national economy beyond its primary function as a fundraising platform. While these figures demonstrate the substantial fiscal contribution of major corporations, the report does not detail future tax policy adjustments or potential changes in corporate tax rates. Observers should note that these findings reflect historical performance and do not necessarily predict future tax collection trends or economic shifts. Further updates from the Revenue Department regarding broader tax collection statistics remain to be seen.
