When to Pay Stamp Duty in Thailand: Exact Timing, Rates, and Calculations for 2026

In Thailand, Stamp Duty is paid on the exact day of title transfer registration at the Land Department office. Not a day before, not a day after. The payment counter sits inside the Land Office itself, and the officer will not stamp your Chanote (title deed) without confirmed payment.

What most foreign buyers miss, however, is that Stamp Duty does not always apply. When a transaction triggers Specific Business Tax (SBT), Stamp Duty is waived entirely. These two charges are mutually exclusive - understanding this one mechanic can save you anywhere from 0.5% to 2.5% of the property value at closing.

This guide covers every element: who pays, when, how much, and how to legally reduce your transaction costs.

Quick Answer

• Stamp Duty rate - 0.5% of the appraised or contractual value (whichever is higher)
• When to pay - on the day of ownership registration at the Land Office
• Who pays - legally the seller, though parties frequently split costs by written agreement
• Mutual exclusion rule - if the seller has owned the property for fewer than 5 years, SBT at 3.3% applies instead of Stamp Duty
• Calculation basis - the higher of the Land Department's appraised value or the contract price
• Payment method - cash or cashier's cheque at the Land Office counter

Scenarios and Options

Scenario 1: Buying a New Condominium from a Developer

The developer is a corporate entity. When selling newly completed units, the company has typically held the property for fewer than 5 years, which triggers SBT at 3.3% rather than Stamp Duty. The foreign buyer typically covers the Transfer Fee of 2%, while SBT falls on the developer's side. Stamp Duty in this scenario is zero.

Many developers in Phuket and Bangkok offer promotional packages where they absorb the Transfer Fee as well - always ask what the split is before signing.

Scenario 2: Buying Secondary Market Property from an Individual

When an individual seller has held the property for more than 5 years, SBT does not apply. Instead, Stamp Duty of 0.5% comes into effect. The seller also pays Withholding Tax on the capital gain, calculated on a progressive scale based on the appraised value and years of ownership.

In practice, the two parties often agree in writing to split all closing costs 50/50. This arrangement must be written into the sale and purchase agreement to be enforceable.

Scenario 3: Acquiring a Villa Through a Thai Company

When land and villa are held inside a Thai limited company and the transaction is structured as a share transfer rather than a direct property transfer, conventional transfer taxes - including Stamp Duty and SBT - do not arise in the same way. Instead, corporate taxes and share transfer duties apply. This route requires a full legal audit of the company structure, including a review of existing liabilities, shareholder records, and compliance history.

Scenario 4: Long-Term Leasehold Registration

Registering a lease of more than 3 years at the Land Office triggers a registration fee of 1% and a reduced Stamp Duty of 0.1% calculated on the total lease value over the full term. This is a separate tax category distinct from freehold ownership transfers.

Main Risks and Mistakes

1. Miscalculating the tax base. The Land Department uses its own official appraised value, which can differ significantly from the market price. If your contract price is lower than the appraised value, the officer will use the appraised figure. If it is higher, the contract price applies. You can check the official appraised value in advance through the Treasury Department website or by visiting the local Land Office.

2. Budgeting for both Stamp Duty and SBT simultaneously. Only one of these two taxes ever applies to a single transaction. Buyers who budget for both are overcounting. The deciding factor is the seller's ownership duration: fewer than 5 years triggers SBT at 3.3%; more than 5 years triggers Stamp Duty at 0.5%.

3. Relying on verbal agreements for cost-splitting. Without a written clause in the sale and purchase agreement, all charges default to the legally designated party. A seller who verbally promised to split costs has no binding legal obligation to follow through. Get it in writing every time.

4. Overlooking Withholding Tax in the deal economics. Even when the buyer only directly pays the Transfer Fee, the seller's Withholding Tax liability affects the net price they are willing to accept. Sophisticated sellers price this tax into their asking price from the start - understanding this helps in negotiations.

5. Confusing purchase-stage taxes with rental income taxes. Stamp Duty is a one-time payment at closing. If you plan to lease out the property afterward, rental income is subject to a separate income tax. For non-residents, a flat 15% withholding rate typically applies, unless a tax treaty between Thailand and your country of tax residency provides a different rate. Thailand has active double taxation agreements with many countries - verify your specific situation with a tax adviser.

FAQ

Who pays Stamp Duty - the buyer or the seller?

Under Thailand's Revenue Code, the seller is the legally designated payer. In practice, most transactions involve a negotiated cost-split, often 50/50, documented in the sale agreement.

Can Stamp Duty be paid before the registration date?

No. All property transfer taxes are paid at the Land Office counter on the day of registration. There is no facility for advance payment.

What is the typical total cost for a buyer purchasing a new condo from a developer?

The primary cost for the buyer is the Transfer Fee at 2% of the appraised value. Some developers absorb part or all of this as a promotional offer. Stamp Duty generally does not apply in developer transactions because the developer triggers SBT instead.

How is Withholding Tax calculated for an individual seller?

It is calculated on the appraised value using Thailand's progressive personal income tax scale (5% to 35%), with a deduction formula based on years of ownership. The longer the seller has held the property, the lower the effective taxable income per year, and therefore the lower the applicable rate.

What is Specific Business Tax and when does it replace Stamp Duty?

SBT is a 3.3% tax levied when the seller has owned the property for fewer than 5 years, or is a company engaged in commercial property sales. When SBT is charged, Stamp Duty is not. The two cannot coexist on the same transaction.

What documents are required at the Land Office on transfer day?

Typically: buyer's passport, sale and purchase agreement, seller's ID or company registration documents, the title deed (Chanote or Nor Sor 3 Gor), and a Foreign Exchange Transaction (FET) certificate for foreign buyers confirming funds were remitted from abroad. Your lawyer will prepare a full checklist in advance.

Can transfer costs be legally reduced?

Yes, in two practical ways. First, negotiate a written cost-sharing arrangement with the seller. Second, consider timing: buying from a seller who has held the property for more than 5 years eliminates SBT at 3.3% and substitutes Stamp Duty at 0.5% - a saving of 2.8 percentage points relative to the transaction value.

Can a foreigner buy land in Thailand and does Stamp Duty apply?

Foreigners cannot directly own land in Thailand. Land is typically held through a Thai limited company or via a registered long-term leasehold. The applicable taxes depend entirely on which ownership structure is used, making legal advice essential before any land acquisition.

As a practical planning rule, budget 4% to 6% of the purchase price to cover all transfer-related costs. Before signing any agreement, ask your lawyer for a written Tax Breakdown that itemises every charge by payer. Always document cost-sharing arrangements in the sale contract - verbal agreements carry no legal weight at the Land Office.
