Effort to add B435bn in annual revenue
The Finance Ministry has proposed a package of 10 tax reforms that are expected to generate more than 435 billion baht in additional annual revenue, with the objective of ensuring that government revenue remains sufficient to accommodate increasing public expenditure in the future.According to the ministry's latest fiscal risk report, if no action is taken to increase government revenue, the ratio of government revenue to GDP could fall below the current level of 15% of GDP, said a ministry source who requested anonymity.
To improve the government's revenue collection capacity over the medium term, the ministry developed a tax structure reform and revenue collection efficiency enhancement plan.
Among the 10 measures, those already implemented in 2026 include the removal of the import duty exemption for low-value goods (the de minimis threshold of 1,500 baht), which is expected to generate an additional 3 billion baht in revenue, and the revision of the automobile excise tax structure based on CO₂ emissions, which is also expected to generate 3 billion baht.
Measures scheduled for implementation in 2027 include the introduction of the top-up tax, which is expected to generate 8.4 billion baht, and the imposition of a 1,000-baht outbound travel tax on Thai nationals travelling abroad, which is expected to generate 12 billion baht.
