Completing a property purchase in Thailand requires a clear understanding of the statutory fees, taxes, and registration costs that apply at the Land Department on the scheduled transfer date. This guide explains each component of the transaction cost structure, identifies which party is typically responsible for payment, provides a worked example using a 10 million THB condominium purchase, and outlines the standard sales and purchase agreement (SPA) execution process for both leasehold and freehold properties. Buyers and sellers should note that while statutory fee rates are fixed nationally, the negotiated split of costs is always a contractual matter between the parties and should be expressly recorded in the SPA prior to execution.
Core Transfer Fees and Taxes
The standard suite of transfer charges applicable to most residential property transactions in Thailand comprises five principal components: the Transfer Fee, Specific Business Tax (SBT), Stamp Duty, Withholding Tax, and, where applicable, the Mortgage Registration Fee. Each is levied against a defined value base, which in practice is the higher of the actual declared transaction price or the Land Department's official appraisal value for the relevant property and location.
Transfer Fee (2 percent):** The Transfer Fee is the principal statutory cost of transferring ownership or long-leasehold interest from the seller to the buyer. It is assessed at a flat rate of 2 percent of the applicable assessed value. Under standard market practice in the Bangkok condo market, the Transfer Fee is customarily split equally between the buyer and the seller, with each party bearing 1 percent. In Phuket and other provincial markets, practice varies more by transaction type, with villa transactions often seeing the seller bear the full 2 percent as part of the negotiation. The Transfer Fee applies to both freehold title transfers (Nor Sor 4 Gor / Chanote) and the assignment or creation of registered 30-year leasehold interests, making it relevant to virtually every structured property acquisition.
Specific Business Tax (3.3 percent):** Specific Business Tax, or SBT, is a value-based levy that applies when the seller is a registered business entity, a developer selling stock-in-trade, or a private individual selling within the five-year holding period following acquisition. The rate is 3.0 percent of the assessed value, plus a 0.3 percent municipal surtax, giving a combined effective rate of 3.3 percent. Critically, SBT replaces Stamp Duty in transactions where it is applicable — the two charges are mutually exclusive, not cumulative. Private individuals selling a property that they have held for more than five consecutive years, and which has been used as their principal residence for at least one year, are typically exempt from SBT and instead pay Stamp Duty at the lower 0.5 percent rate. SBT is almost universally a seller's cost in the Thai market, as it arises from the seller's taxable disposal event, though it is not uncommon for developers to advertise "buyer pays all fees" promotional packages that effectively roll the SBT cost into the headline purchase price.
Stamp Duty (0.5 percent):** Stamp Duty applies to property transfers that fall outside the scope of Specific Business Tax — most commonly, resales by private individuals who have owned the property for more than five years. It is assessed at 0.5 percent of the assessed transfer value. As with SBT, Stamp Duty is technically a seller's obligation under Thai tax law, although the SPA will usually specify the agreed allocation between the parties. Buyers should verify the seller's holding period and tax registration status during the due diligence phase, as misclassification between SBT and Stamp Duty can result in a difference of up to 2.8 percent of the property value in either direction, which can be a material sum for mid-range and luxury assets.
Withholding Tax (1 percent):** Withholding Tax on property transfers is deducted at source by the Land Department at the time of transfer, at a flat rate of 1 percent of the assessed value. It functions as a prepayment against the seller's personal or corporate income tax liability arising from the disposal. For individual sellers, the 1 percent withheld is creditable against their annual personal income tax return and may result in a refund if the actual capital gain, calculated using the Revenue Department's progressive formula, is lower than the flat amount withheld. For corporate sellers and developers, the withholding tax is treated as a tax payment against their annual corporate income tax liability. Customarily, Withholding Tax is treated as a seller's cost and is deducted from the sale proceeds rather than paid separately, though the SPA should always confirm the exact mechanics to avoid disputes at the transfer appointment.
Mortgage Registration Fee (1 percent)
Buyers financing their acquisition with a Thai bank mortgage will incur a separate Mortgage Registration Fee, assessed at 1 percent of the registered loan principal amount — not of the property value. This fee covers the Land Department's cost of registering the lender's security interest (a mortgage or, more commonly in Thailand, a suretyship-cum-mortgage structure) against the title deed. The Mortgage Registration Fee is always the buyer-borrower's responsibility. For example, a buyer purchasing a 10 million THB condo with a 70 percent loan-to-value mortgage of 7 million THB would pay 70,000 THB in Mortgage Registration Fee. Buyers should also budget for the bank's loan arrangement fee, typically between 1 and 1.5 percent of the loan amount, and a nominal fire insurance premium, which most lenders require as a condition of disbursement.
Worked Example: 10 Million THB Bangkok Condominium
To illustrate the cumulative transaction costs, consider a resale of a 10 million THB freehold condominium in Bangkok, in which the private-individual seller has owned the unit for seven years, triggering Stamp Duty rather than Specific Business Tax, and the buyer is financing 60 percent of the purchase price with a Thai mortgage. The Land Department's assessed value equals the contract price for simplicity.
On the seller side, the costs are: Stamp Duty at 0.5 percent equalling 50,000 THB, Withholding Tax at 1 percent equalling 100,000 THB, and the seller's half of the Transfer Fee at 1 percent equalling 100,000 THB, giving total seller-side costs of 250,000 THB, or 2.5 percent of the sale price. On the buyer side, the costs are: the buyer's half of the Transfer Fee at 1 percent equalling 100,000 THB, plus the Mortgage Registration Fee at 1 percent of the 6 million THB loan equalling 60,000 THB, for total buyer-side costs of 160,000 THB, or 1.6 percent of the purchase price. Combined statutory costs for the transaction total 410,000 THB, representing approximately 4.1 percent of the 10 million THB consideration. If the same unit were being sold by a developer or an individual within the five-year SBT window, the Stamp Duty of 50,000 THB would be replaced by Specific Business Tax of 330,000 THB, increasing total transaction costs to 690,000 THB or 6.9 percent of the consideration.
Leasehold Versus Freehold Considerations
The fee structure for leasehold acquisitions differs from freehold purchases in several important respects. The initial creation or assignment of a registered 30-year leasehold interest is subject to the same 2 percent Transfer Fee as freehold, calculated against the capitalised or prepaid lease value rather than the underlying land value. Because most leasehold transactions are structured as new grants from a developer-landlord, rather than assignments from a previous private lessee, Specific Business Tax at 3.3 percent is the norm rather than Stamp Duty. Leasehold properties do not transfer underlying land ownership, so the Land Department's appraisal methodology focuses on the present value of the lease term and any improvements, which can result in lower assessed values for equivalent-grade properties compared with freehold comparables. Leasehold buyers who require financing should note that Thai banks typically offer lower loan-to-value ratios for leasehold collateral — commonly 50 to 60 percent rather than the 70 to 80 percent available for freehold condominiums — and that some lenders impose a minimum remaining lease term of 25 years at the point of loan origination.
The Typical SPA Process
The standard transaction process for residential property in Thailand follows a predictable sequence, beginning with the execution of a Sales and Purchase Agreement and concluding with the transfer appointment at the provincial or district Land Office. After agreeing on price and commercial terms, the buyer typically pays a reservation deposit of between 50,000 and 200,000 THB to take the property off the market, followed within 14 to 21 days by the signing of the formal SPA and payment of a 10 to 15 percent deposit (inclusive of the reservation amount). The SPA will specify the balance payment mechanism, the contractual completion or transfer date, and the agreed allocation of all transfer fees, taxes, and Land Department charges, along with any developer warranties or seller representations regarding title, occupation status, and outstanding utility or maintenance charges.
During the interval between SPA signing and the transfer date, the buyer's legal representative will conduct a full title search at the Land Department to verify the seller's registered interest, confirm the absence of unauthorised encumbrances, liens, or third-party claims, and cross-check the Land Department's official appraisal value. Where mortgage financing is involved, the bank will conduct its own valuation, prepare the loan documentation, and confirm disbursement readiness, typically requiring the buyer to settle the loan arrangement fee and execute the mortgage deed in advance of the transfer appointment.
On the scheduled transfer date, both parties or their authorised attorneys attend the Land Department with the original SPA, valid identification documents, and evidence of any necessary tax clearances. The Land Officer verifies the documents, calculates the final fees and taxes based on the higher of contract value or official appraisal, and collects payment — most offices accept certified banker's drafts or direct bank transfers. Once all charges are paid and the transfer is registered, the Land Department issues the new title deed or updated lease registration to the buyer, and the sale proceeds, less seller-side fees and any applicable withholding, are released to the seller. Following transfer, the buyer's solicitor typically handles the registration of the change of ownership with the relevant juristic person management office, the Metropolitan Electricity Authority, and the Provincial Waterworks Authority to ensure a clean handover of all service accounts and common-area membership rights.
