BANGKOK, THAILAND – Thailand’s excise authorities set out a six-point tax reform plan designed to curb pollution, improve public health and boost revenue from 2027.
Global pressure drives tax shift
In bustling Bangkok, the persistent winter smog was described as no longer just a nuisance but a political mandate, as Thailand stood at a crossroads between traditional growth policies and global environmental demands. The excise department drafted an ambitious package of six new tax initiatives intended to promote ecological sustainability and protect public health.
“These measures were not a purely domestic project; they aimed to align Thailand with shifting global trade standards, where climate protection and public health had become hard currency,”
said Pornchai Thiraveja, director-general of the excise authority.
Carbon, luxury and green fuel in focus
One measure extended excise coverage to environmentally harmful products, responding in part to the European Union’s Carbon Border Adjustment Mechanism, which taxed imports based on their CO₂ footprint. This step was presented as preparation for a national CO₂ tax and emissions trading system already envisaged in Thailand’s climate law, recently approved by the cabinet. A second measure expanded the tax base for luxury goods and services to raise revenue without directly burdening lower-income groups, hitting the kingdom’s growing high-end consumption.
Health taxes: salt and tobacco overhaul
A third element introduced incentives for environmentally friendly products, with particular emphasis on sustainable aviation fuel and various biofuels, signalling industry to invest in green technologies and reduce reliance on fossil fuels. The fourth measure targeted high sodium intake, which was linked to widespread kidney disease and hypertension that placed heavy costs on the health system. A specific salt tax was planned so that higher prices for salty products would steer consumers toward healthier options and push manufacturers to reformulate.
Battery innovation and cigarette reform
The fifth reform restructured battery taxation around technical criteria such as charging cycles and energy density, giving more efficient batteries a more favourable tax treatment than outdated models. Authorities expected this to cut environmental damage from short-lived batteries and promote innovation in the battery sector, deemed crucial for Thailand’s growing electric vehicle market. The sixth and most complex measure reorganised the cigarette tax system, which had been based on two tiers and taxed packs differently depending on whether they cost 72 baht or less, at 25 percent, or more than 72 baht, at 42 percent.
Closing loopholes and supporting state tobacco
The dual cigarette structure had encouraged manufacturers to shift aggressively toward cheaper products priced under 72 baht to avoid the higher rate, expanding the market share of low-cost brands instead of cutting tobacco use or maximising revenue. The excise authority intended to propose a single, uniform tax rate to the cabinet to end such distortions so competition would be driven by quality and brand rather than tax thresholds. Support programmes were planned for the Thai Tobacco Authority, which faced the challenge of restructuring in a changing market while the government sought to promote cigarette exports to new markets.
Crackdown on smuggling and new tax bases
Officials warned that any rise in tobacco taxes risked fuelling the black market, prompting plans to tighten enforcement against illegal cigarette imports at the borders. Reference prices used for tax calculation were to be reviewed so they reflected real market values and reduced under-invoicing and tax evasion, making the system more transparent and less open to manipulation. Existing exemptions for fruit and vegetable juices were also under reassessment because many such drinks contained high sugar levels, reflecting a broader health policy approach.
Higher service costs and ambitious revenue goals
The department also examined extending excise taxes to certain service fees, which could make everyday services more expensive as part of a broader effort to stabilise revenue by widening the tax base. For 2026 the authority targeted 578 billion baht in excise income, rising to 611 billion baht in 2027 once all measures took effect, underlining the fiscal scale of the reform. Critics cautioned that if companies passed higher taxes directly on to customers, living costs could rise and dampen consumption in an already challenging economic climate.
Aviation sustainability and tourism image
In aviation, environmental commitment was already being rewarded as Bangkok Airways recently received a prestigious five-star sustainability award from the Tourism Authority of Thailand. The recognition highlighted that companies acting proactively could gain visibility in a tourism market where responsible travel was increasingly a selling point. Observers suggested the new tax regime could reinforce this trend by making environmentally friendly behaviour more attractive and pushing heavier levies on major polluters.
Impact on daily life and delicate balance
For residents and expatriates alike, the plans raised practical questions over whether street food dinners would become more expensive under a salt tax and whether smokers would have to pay more for cigarettes, with the text indicating the likely answer was yes. Products deemed unhealthy or environmentally harmful were expected to rise in price, while innovation and healthier consumption patterns were meant to be encouraged. The government faced a balancing act: it needed revenue and behavioural change but had to avoid overburdening low-income households, particularly where staple foods were concerned.
Betting on innovation and long-term health
The reform was framed as a wager on technological progress, in which more efficient batteries and cheaper biofuels could eventually lower costs despite initial tax pressure. In health care, lower salt intake and reduced smoking were expected to cut long-term treatment expenses for chronic diseases and free public funds for other priorities, seen as an investment in a healthier population. Authorities stressed that announcing the measures well ahead of 2027 was intended to give businesses time to adjust and consumers room to rethink habits, smoothing the transition to what was described as a major tax policy shift toward quality, sustainability and health.
