Property Taxes in Thailand: Withholding Tax and Stamp Duty Explained for 2026
A buyer purchasing a condominium in Phuket for 12 million baht can expect to pay roughly 240,000 baht in taxes and registration fees alone - costs that many investors only discover when they are already standing at the Land Office counter with no room to negotiate.
Thailand applies four main taxes and fees when transferring property ownership. Two of them generate the most confusion among foreign buyers: withholding tax and stamp duty. Understanding how each works allows you to forecast your total transaction budget accurately and negotiate cost-sharing with the seller before signing anything.
One important nuance: the tax burden in Thailand depends not only on the sale price, but also on how long the seller has owned the property, whether the seller is an individual or a company, and the Government Appraised Value set by Thailand's Treasury Department. The gap between market price and appraised value can reach 30 to 50 percent, which directly affects the tax base.
Quick Answer
- Transfer fee is 2% of whichever is higher - the Government Appraised Value or the contracted sale price
- Stamp duty is 0.5% of the higher of the two values, but only applies when Specific Business Tax is NOT charged
- Specific Business Tax (SBT) is 3.3% and applies when the seller has owned the property for fewer than 5 years (or has not been registered at that address for more than 1 year)
- Withholding tax for individual sellers is calculated using Thailand's progressive Personal Income Tax (PIT) scale, weighted by years of ownership; for corporate sellers, it is a flat 1% of the higher value
- SBT and stamp duty are mutually exclusive - if SBT applies, stamp duty is waived
- All taxes are paid on the day of ownership registration at the Land Office - the transaction cannot be completed without payment
Scenarios and Options
Scenario 1: Buying from a Developer (Corporate Seller)
A developer selling property as its core business activity will almost always be subject to Specific Business Tax at 3.3%. Withholding tax for a corporate entity is a straightforward flat rate of 1% of the appraised value or contracted price, whichever is higher.
In practice, most developers in Phuket and Bangkok absorb SBT and withholding tax themselves, while splitting the 2% transfer fee equally with the buyer (1% each). This is market convention, not a legal requirement - always verify the exact cost allocation in your purchase contract.
Example: a condominium priced at 8 million baht, with a Government Appraised Value of 6.5 million baht. All calculations use the contracted price (the higher figure). Transfer fee: 160,000 baht. SBT: 264,000 baht. Withholding tax: 80,000 baht. Total tax burden: 504,000 baht.
Scenario 2: Buying from an Individual (Resale, Owned Less Than 5 Years)
This is where calculations become significantly more complex. For individual sellers, withholding tax follows Thailand's progressive Personal Income Tax scale and factors in the number of complete years the seller has held the property.
The method works like this: the Government Appraised Value is divided by the number of full years of ownership (capped at 10). That annual figure is then taxed at PIT rates ranging from 0% to 35%, and the resulting annual tax is multiplied back by the number of years owned.
Example: seller has owned a unit for 3 years, Government Appraised Value is 10 million baht. Annual base: 10,000,000 / 3 = 3,333,333 baht. At 2026 PIT rates, the annual tax on this figure is approximately 363,000 baht, giving a total withholding tax of 363,000 x 3 = roughly 1,089,000 baht. SBT at 3.3% also applies because ownership is under 5 years.
Scenario 3: Buying from an Individual (Resale, Owned 5 Years or More)
If the seller has held the property for 5 years or more - or has been officially registered at that address for more than 1 year - SBT does not apply. Instead, the cheaper stamp duty of 0.5% is charged. Withholding tax is still calculated using the progressive PIT method, but dividing by a larger number of years reduces the annual base and therefore the effective tax rate.
Example: property appraised at 10 million baht, held for 7 years. Annual base: 10,000,000 / 7 = 1,428,571 baht. Annual PIT on that amount: approximately 178,500 baht. Total withholding tax: 178,500 x 7 = roughly 1,249,500 baht. Stamp duty: 50,000 baht. Transfer fee: 200,000 baht.
Note that while the absolute withholding tax figure is higher due to the multiplier effect of more years, the absence of SBT (3.3% on the full price) makes this scenario more cost-efficient overall.

| Parameter | Developer (Corporate) | Resale Under 5 Years | Resale Over 5 Years |
|---|---|---|---|
| Transfer Fee | 2% (often split 50/50) | 2% (negotiable) | 2% (negotiable) |
| Stamp Duty | Not applicable (SBT applies) | Not applicable (SBT applies) | 0.5% |

| Calculation Complexity | Straightforward | High | High |
Main Risks and Mistakes
1. Underreporting the sale price in the contract. Some sellers propose listing a lower figure in the purchase agreement to reduce the tax base. The Land Office uses the Government Appraised Value as the minimum calculation floor, so the actual savings are limited. More importantly, underreporting exposes both parties to criminal liability for tax evasion under Section 37 of Thailand's Revenue Code.
2. Misunderstanding who pays what. Thai law does not specify which party must pay each particular tax - it is all determined by the contract. If the contract is silent on the matter, the default position places all taxes on the seller. In practice, buyers frequently agree to a 50/50 split on the transfer fee without realising they have no legal obligation to do so.
3. Confusing SBT with stamp duty. These two charges are mutually exclusive and can never apply simultaneously. If a lawyer or agent includes both in their cost estimate, treat it as a red flag regarding their competence.
4. Ignoring the Government Appraised Value cycle. The Treasury Department revises appraised values every 4 years. Many areas of Phuket are due for revaluation in 2026-2027. Post-revision, appraised values could increase by 15 to 30 percent, directly raising the tax base for any transaction that closes after the update.
5. Skipping the pre-registration cost estimate. Before completing a transaction, you can request a free preliminary tax calculation from your local Land Office. This takes less than an hour and gives you an exact breakdown of all fees payable on the day of registration. Very few buyers take advantage of this service.
6. Withholding tax for non-resident foreign sellers. If the seller is a foreign national who is not a Thai tax resident, withholding tax is still deducted at source. The seller may be able to offset it against taxes owed in their home country only if a double taxation agreement is in place between Thailand and that country.
FAQ
Who pays withholding tax when buying property in Thailand? Withholding tax is deducted from the amount the seller receives. It is technically the seller's liability. However, the contract can redistribute this cost between both parties. On the primary market, developers typically absorb withholding tax themselves.
Can Specific Business Tax be avoided? Yes - if the seller is an individual who has owned the property for more than 5 years, or has been registered as a resident at that address for more than 1 year. In that case, SBT at 3.3% is replaced by stamp duty at 0.5%.
How is withholding tax calculated for a corporate seller? A flat rate of 1% is applied to whichever is higher - the Government Appraised Value or the contracted sale price. No progressive scale is involved.
Exactly when are taxes paid in a Thai property transaction? All taxes and fees are paid on the day of ownership registration at the Land Office. They are deducted from the transaction proceeds before payment reaches the seller. Registration cannot proceed until all taxes are settled.
Does the property type - condo vs villa - affect tax rates? The applicable rates are the same for all residential property types. A structural difference arises when a villa is held through a Thai company: selling the company shares rather than the land title bypasses Land Office registration fees, but creates separate corporate tax obligations.
Can withholding tax be refunded? For Thai tax residents, withholding tax is credited against the annual PIT return (form PND 90 or 91). If the total tax owed is less than the amount withheld, the difference can be refunded. For non-residents, a refund is generally not available in practice.
What is the Government Appraised Value and how do you check it? It is the official valuation set by Thailand's Treasury Department, used as the minimum tax base for property transactions. You can check it at treasury.go.th or request the figure directly from your local Land Office. It is typically 20 to 50 percent below market value.
What taxes does a foreign buyer actually pay when purchasing a condominium? By default, the buyer has no obligation to pay withholding tax, SBT, or stamp duty. The buyer's mandatory cost is the 2% transfer fee, which is frequently split equally with the seller. Any other arrangement must be explicitly stated in the contract.
Is legal advice necessary for calculating property taxes in Thailand? Strongly recommended. Withholding tax calculations for individual sellers require accurate knowledge of the progressive PIT scale, precise ownership duration, and the correct Government Appraised Value. An error in the calculation can translate into a shortfall of hundreds of thousands of baht.
Smart tax planning for a Thai property purchase starts well before you sign anything. Request a preliminary tax estimate from the Land Office, verify the Government Appraised Value on the Treasury website, and make sure your contract clearly states which party bears each cost. Each of these steps takes under an hour and can save you a significant sum.
