Thailand's property tax system works differently from what most foreigners are used to at home. There is no single "property tax" in the familiar sense — instead, several different payments apply at different points: at purchase, while owning, when earning rental income, and when selling. Here's a breakdown.

Important: This article is for general information only. Tax circumstances are individual. Always consult a licensed Thai lawyer and tax adviser before any transaction.

1. Taxes at Purchase (Transfer Fees)

When registering a transfer of ownership or a leasehold contract at the Land Department, the following fees apply:

Fee Rate Notes
Transfer fee 2% of assessed value Usually split equally between buyer and seller, but this is negotiable
Stamp duty 0.5% of assessed or contract value (whichever is higher) Applies if the seller has owned for 5+ years
Specific Business Tax (SBT) 3.3% of assessed or contract value Applies if the seller has owned for fewer than 5 years; replaces stamp duty
Withholding tax 1% for companies; progressive rate for individuals Paid by the seller

In practice, the buyer typically bears the transfer fee (1% as their share) plus their portion of stamp duty. The exact split is set in the purchase agreement.

2. Annual Land and Building Tax

Introduced a few years ago, replacing the old house and land tax.

Rates for residential use: - Value up to ฿50M — 0.02% - ฿50M–75M — 0.03% - ฿75M–100M — 0.05% - Over ฿100M — 0.1%

Rates for rental/commercial use: - Up to ฿50M — 0.3% - ฿50M–200M — 0.4% - Over ฿200M — 0.7%

For most villas on Koh Samui, the annual land and building tax is relatively low — typically ฿20,000–100,000 per year for a property valued at ฿10–30 million.

3. Rental Income Tax

This is one of the most important considerations for investors.

Individual who qualifies as a Thai tax resident (spending 180+ days per year in Thailand) must declare rental income from Thai property. Progressive personal income tax applies:

Taxable income Rate
0–150,000 baht 0%
150,001–300,000 baht 5%
300,001–500,000 baht 10%
500,001–750,000 baht 15%
750,001–1,000,000 baht 20%
1,000,001–2,000,000 baht 25%
2,000,001–5,000,000 baht 30%
Over 5,000,000 baht 35%

Deductible expenses (management fees, repairs, maintenance) may reduce the taxable base, or a standard deduction of 30% of gross rental income may be applied.

Non-Thai tax resident earning income from Thai sources is also liable for Thai personal income tax at the same rates, though enforcement on non-residents is inconsistent. This doesn't mean it can be ignored — it means professional advice is essential.

Thai company structure: rental income is subject to corporate income tax (20%; reduced rates of 15% for smaller companies), plus additional considerations when distributing profits to shareholders. More complex to administer, but potentially more efficient at higher income levels.

4. Taxes on Sale

The seller pays withholding tax. For individuals, this is calculated using the progressive personal income tax scale, with deductions based on years of ownership (the longer you own, the lower the taxable base). SBT (3.3%) or stamp duty also applies, depending on the holding period (see above).

Thailand does not have a separate capital gains tax, but the economic effect is similar — appreciation is effectively taxed via withholding tax and SBT on sale.

5. Your Country of Tax Residence

Thai tax rules apply to Thai-source income. However, your country of residence may also have reporting requirements for foreign income and assets. Tax treaties between Thailand and many countries (UK, Germany, Australia, and others) govern where tax is paid.

Check with a tax adviser both in Thailand and in your home country — double taxation arrangements are assessed case by case.
