Land and Building Tax is an annual tax on property, paid to the local authority (the tambon or municipality) by whoever owns or holds the property on 1 January. It is calculated on the official appraised value.
Rates
The rate depends on how the property is used. These are the bands generally applied (percentages of appraised value):
| Use | Rate |
|---|---|
| Main home, owner in the house registration (land and house) | First 50m baht exempt, then 0.03% to 0.10% |
| Main home, condo or building only | First 10m baht exempt, then 0.02% to 0.10% |
| Second home, or a home you're not registered in | 0.02% to 0.10%, no exemption |
| Commercial and other use | 0.30% to 0.70% |
| Vacant or unused land | As commercial, rising over time |
Most foreign owners are not in a house registration book, so the second-home rate is the usual starting point. For a 10-million-baht condo that means roughly 2,000 baht a year.
Rented-out property: check your classification
A property that is let out may be assessed under "other use" rather than as a residence, at a much higher rate. Sources don't agree on how holiday and long-term lets are treated, and local offices vary. When your assessment notice arrives, check which category you've been placed in and ask the local office if it looks wrong.
When to pay
Normally assessment notices go out by the end of April and payment is due in June, with instalments allowed for larger bills. In 2026 the government pushed the timetable back: notices in May, payment in July, and instalments over July, August and September. Late payment carries surcharges, so put it in your calendar.
Practical tips
- The notice goes to the address the local office has for you. If you live abroad, make sure your manager or a trusted contact receives it.
- Keep the receipt with your property records; you may be asked for it when you sell.
