Thailand’s Land and Building Tax replaced earlier local property-tax systems, but an explainer recorded when the law first took effect can contain rates, reductions, and exemptions that no longer apply. The safest way to review a bill is to check the current assessment and notice issued for the property, then confirm any disputed detail with the responsible local authority.
What determines the assessment
In broad terms, the tax calculation depends on the assessed value used for tax purposes and the property’s legally classified use. The categories can include agriculture, residential use, other uses, and unused land or buildings. The applicable rate and any relief depend on the law and rules in effect, the property facts, and the local assessment. Statutory maximum rates are ceilings; they should not be treated as the exact rate on every bill.
The Land and Building Tax Act B.E. 2562 (2019) sets the legal framework. The Department of Local Administration’s copy of the Act is a useful starting point. For implementation guidance, see the DLA’s land and building tax procedures and its LTAX public service.
Checklist: review a tax notice
- Confirm the property details. Check the parcel, building, ownership or possession information, and the period covered by the notice.
- Check the assessed value. Compare the value and property details shown in the notice with the official assessment information available to you.
- Check the actual use. The classification depends on how the land or building is used under the applicable rules. Do not assume a category based only on the property’s name or intended future use.
- Review the calculation and any relief. Look for the rate applied, tax base, exemptions or reductions, and the legal basis described in the notice.
- Note the payment deadline and contact point. Use the date and payment instructions on the current notice; do not rely on a deadline from an older article or video.
If something appears incorrect
Contact the local authority named on the notice and ask which property information or legal rule determined the assessment. Keep a copy of the notice and relevant supporting records, such as land documents, building details, or evidence of actual use. If you intend to dispute an assessment, follow the objection process and deadlines stated by the authority and the law. A late objection may affect the remedies available.
Why older rate tables can mislead
Rates and temporary relief announced during the first years of implementation are not automatically current. The 2020-era figures in older explainers should not be reused as a present-day estimate. Check current DLA guidance and the local notice for the relevant tax year before budgeting or making a property decision.
Questions to ask your local authority
- Which assessed value and property records were used?
- How was the actual use classified?
- Which rate and relief provisions apply to this tax year?
- What documents and deadline apply if I believe the notice is incorrect?
