Thailand Property Tax Guide: What Buyers and Sellers Pay

guides.reviewedLabel

Thailand property tax covers four main charges at purchase and sale — transfer fee, Specific Business Tax or stamp duty, and withholding tax — plus an annual Land and Building Tax once you own. This guide explains the rates, who typically pays, and how to budget for each.

Thailand property tax applies at two separate moments: once when a property changes hands, and every year afterward while you own it. At transfer, the Land Department collects a 2% transfer fee plus either a 3.3% Specific Business Tax or a 0.5% stamp duty, and deducts withholding tax from the seller's proceeds. Once registered, owners pay an annual Land and Building Tax based on the government-appraised value. Buyers and sellers traditionally split these costs differently, and knowing the rules before you sign a reservation agreement prevents disputes over closing costs.

Transfer Fee: The 2% Baseline Charge

The transfer fee is calculated at 2% of the property's official appraised value, not the actual sale price, and is paid at the Land Office on the day ownership is registered. For example, with a condominium appraised at 3,000,000 baht, the total transfer fee is THB 60,000. You pay THB 30,000 and the seller pays THB 30,000, unless you negotiate otherwise. By convention the fee is often split 50/50, though the split is negotiable and not fixed by law.

Reduced Transfer Fee Schemes

The Thai government has periodically cut the transfer fee well below 2% for qualifying residential sales, but these reductions have historically targeted Thai nationals, not foreign condominium buyers. Because relief measures are extended, narrowed, or allowed to lapse at different points, confirm current eligibility directly with the Land Office or a local lawyer before assuming a discount applies.

Specific Business Tax vs. Stamp Duty: Which One Applies

Specific Business Tax (SBT) and stamp duty are mutually exclusive — a transaction is charged one or the other, never both. The Specific Business Tax applies when a property is sold within five years of the seller purchasing it. The rate is 3.3% of the appraised value or the registered sale price, whichever is higher.

Stamp duty is the lighter-touch alternative that applies once a seller has held the property long enough. Stamp duty applies instead of the Specific Business Tax when the seller has owned the property for more than five years. The rate is 0.5% of the registered value. A seller who has also kept their name in the house registration book (tabien baan) for at least twelve months can qualify for stamp duty treatment even inside the five-year window, since that residency record signals the sale is not a commercial transaction.

Withholding Tax: Deducted From the Seller's Proceeds

Withholding tax functions as an advance payment of income tax on the seller's gain and is deducted at the Land Office on transfer day, before the seller receives the remaining proceeds. Withholding tax is deducted at the Land Department and represents a prepayment of income tax on the seller's gain. The calculation method differs significantly between corporate and individual sellers.

Corporate Sellers

For a company selling property, the rule is straightforward. When a company sells property, withholding tax is simply 1% of the appraised value or declared sale price (whichever is higher). This amount is credited against the company's annual corporate income tax liability.

Individual Sellers

Individual sellers face a more complex, progressive calculation. For individual sellers, the calculation is more complex and uses a progressive rate structure based on appraised value and years of ownership. The deduction percentage is applied to the appraised value to determine "deemed income." This deemed income is then divided by years of ownership and taxed at progressive personal income tax rates. The deduction percentage itself scales with how long the seller has held the property, starting near 92% after one year of ownership and falling to a floor of 50% once a property has been held for eight years or more, which generally lowers the effective tax burden for longer-term owners.

Who Typically Pays What at Closing

Thai law assigns legal liability for each charge, but the final allocation between buyer and seller is always negotiable and should be written into the sale and purchase agreement. The 2% Transfer Fee is typically split 50/50 between the buyer and seller, but this is negotiable. The seller is legally responsible for paying the SBT or Stamp Duty and the Withholding Tax, since both of those charges are calculated against the seller's gain or business status.

Foreign buyers purchasing a freehold condominium unit should budget mainly for their share of the transfer fee plus any mortgage registration fee, since SBT and withholding tax fall on the seller.

Leasehold Transactions Cost Less at Registration

Leasehold arrangements, common for land and houses that foreigners cannot own freehold, carry a lighter registration bill than a freehold transfer. The leasehold registration fee for property is calculated at 1%, while a stamp duty of .1% is also applied. This results in a 1.1% fee applied to the total amount of the lease over the duration of its full term, payable when the lease is first registered, renewed, or assigned to a new party.

Annual Land and Building Tax: The Ongoing Cost of Ownership

Beyond the one-time transfer taxes, every property owner in Thailand pays an annual Land and Building Tax based on the government-appraised value, billed each year by the local municipality. Rates vary by how the property is used, and exemption thresholds protect smaller residential holdings.

Residential Property Rates

For a primary residence where the owner holds both the land and the house, the first 50 million Baht of appraised value is tax-exempt. Above that threshold, and for second homes or rental units that carry no exemption, rates generally start around 0.02% of appraised value on the lower value bands and rise toward 0.10% on the portion valued over 100 million baht.

Commercial, Agricultural and Vacant Land Rates

Commercial and industrial land is taxed more heavily than residential property. Land for commercial and industrial use and vacant land have a tax ceiling of 1.2%, and the effective rate is 0.3-0.7%, while agricultural land carries the lowest rates of the four categories. The landowner is exempt from the tax if they are individuals and the land price does not exceed 50 million baht, a threshold specific to farmland owned by an individual rather than a company. Vacant residential land is generally taxed at the higher commercial-use rate until it is built on.

Budgeting for Total Transaction Cost

A realistic rule of thumb for a standard freehold condominium sale is that the total government cost for a property transfer in Thailand typically ranges from 2.5% to over 6.3% of the property's official appraised value, depending mainly on how long the seller has owned the unit and whether SBT or stamp duty applies. Buyers purchasing directly from a developer should also expect the developer, as a real estate business, to be subject to SBT rather than stamp duty, a cost developers commonly fold into the quoted price rather than itemize separately.
