Thailand Condominium Tax Guide 2025: Essential Rules for Buyers, Sellers & Owners

A practical guide to transfer fees, withholding tax, rental income rules, and land and building tax for individuals investing in Thai condominium property.

This memorandum outlines the principal taxes and fees for purchasing, selling, and renting condominium units in Thailand. It is a practical guide for private individuals and investors seeking to understand the key tax implications of acquiring, owning, or disposing of condominium property in the Thai market.

A. Fees and Taxes Upon Transfer of Ownership

The transfer of ownership of a condominium unit involves the following fees and taxes, payable at the Land Office upon registration.

1. Transfer Fee

The transfer fee is 2% of the appraised value as determined by the Land Office. Under Section 457 of the Civil and Commercial Code (CCC), this fee is typically shared equally between the buyer and seller unless otherwise agreed in writing.

2. Withholding Tax (WHT) / Income Tax on Sale

For individuals, income tax on the gain from the sale of a condominium unit is collected as a final withholding tax at the time of ownership transfer. The amount is calculated by the Land Office using a progressive formula based on:

• The official appraised value of the property; and

• The length of time the property has been owned.

A standard deduction is applied according to the number of years the seller has owned the property (see table below). The remaining taxable portion is then subject to Thailand’s progressive personal income tax rates, ranging from 0% to 35%. This payment fully satisfies the seller’s personal income tax obligation for the transaction and does not need to be reported in the annual tax return.

Years Held	Taxable Income (%)
1 Year	92%
2 Years	84%
3 Years	77%
4 Years	71%
5 Years	64%
6 Years	60%
7 Years	55%
8+ Years	50%

3. Stamp Duty or Specific Business Tax (SBT)

Stamp Duty is levied at 0.5% of the higher of the appraised value or the actual transaction value, but only if the property has been held for more than five years.

Specific Business Tax (SBT) applies at a rate of 3.3% of the higher value if the property is sold within five years or the sale is made for commercial or profit-making purposes.

Unless otherwise agreed, the seller is responsible for these taxes.

The same taxes and fees apply upon resale of a condominium.

B. Rental Income and Withholding Tax (“WHT”)

Rental income from a condominium unit is subject to personal income tax and must be reported in the owner’s annual income tax return.

Thailand has Double Taxation Agreements (“DTAs”) with numerous countries, stipulating that income derived from property in Thailand is taxable in Thailand. If the owner is a non-resident (spending fewer than 180 days per year in Thailand), the tenant must withhold 15% of the monthly rent and remit it directly to the Revenue Department. This payment fully satisfies the owner’s personal income tax obligation for this income, and it does not need to be reported in the annual tax return.

If the owner is a Thai tax resident and the tenant is a Thai juristic person (e.g., a company), the tenant must withhold 5% of the monthly rent. The withheld amount will be credited toward the owner’s final income tax liability.

In both cases, the withholding tax must be remitted to the Revenue Department within seven days of the following month. Both the tenant and the owner are jointly liable for ensuring correct WHT payment. Late payment incurs interest at 1.5% per month, plus potential fines.

C. Land and Building Tax

Condominium units are subject to the Land and Building Tax, even though ownership does not extend to the underlying land. The tax applies to the unit itself and is calculated based on its official appraised value.

If used for residential purposes, the tax is charged at progressive rates ranging from 0.02% to 0.1% per year, with higher-value properties taxed at higher rates.

A primary residence exemption may apply if:

• The owner’s name is recorded in the house registration book; and
• The appraised value does not exceed THB 50 million.
