In 2025, Thailand is taking a significant step in tax reform: Parliament is reviewing a bill to introduce a unified land tax aimed at encouraging rational land use and boosting local budgets. As reported by Bangkok Post, the draft law sets differentiated rates depending on land type and usage.
What tax rates are proposed?
The new land tax rates will be:
- 0.2% — for agricultural land;
- 0.5% — for residential plots (private homes, housing complexes);
- 2% — for commercial and industrial land (hotels, malls, factories);
- 5% — for undeveloped plots during the first 3 years after valuation.
If a plot remains unused, the rate will double to 10% in the following 3 years — a measure aimed at curbing speculation and idle land holdings.
Who is exempt from the tax?
The bill includes relief for small landowners:
- No tax on agricultural land valued below 50 million THB;
- families owning a single residential plot below a threshold (to be set by provinces) are exempt;
- exemptions remain for state land, religious sites, and temple gardens.
Thus, the main burden will fall on large owners and investors holding land “in reserve.”
Goals of the reform
According to the Ministry of Finance and the Department of Lands, the reform has three key goals:
- Stimulating development — owners will be motivated to build, rent, or sell idle plots;
- Reducing speculation — high rates on vacant land will make landholding unprofitable;
- Boosting municipal budgets — funds will go to infrastructure, transport, and environmental projects.
How will this affect the real estate market?
Experts predict:
- Increased supply — owners will actively bring idle plots into circulation;
- Higher prices for developed properties — part of the tax may be passed to tenants and buyers;
- Lower prices for undeveloped plots — demand for “sleeping” land will drop due to future costs;
- Growth of the rental market — owners will prefer long-term leases over land storage.
When will it take effect?
The law is expected to take effect on January 1, 2026. Throughout 2025, all land plots will be reassessed under the new system. Owners will receive notifications with cadastral values and future payments.
How should owners prepare?
- Check your land status at the Department of Lands;
- Confirm if the plot is in a future development zone (e.g., near metro or EEC);
- Explore options for land use: construction, leasing, developer partnerships;
- Consult a tax advisor on optimization strategies.
Conclusion
The new land tax is not just a fiscal measure, but a tool for economic transformation. Thailand aims to shift from speculative landholding to sustainable, productive resource use. For some, it will be a burden; for others, an opportunity. The key is to stay informed and act wisely. In 2025, it’s time to reassess your land assets — before the tax is due, but while the future is already clear.
