Stamp Duty in Thailand: When It Applies and How Much Buyers Actually Pay
Buying property in Thailand involves several transfer-related costs, and Stamp Duty is one that often catches buyers off guard - not because it is expensive, but because it may not apply at all depending on who you are buying from. Understanding when this fee kicks in, and when it is replaced by a different tax, is essential before you sign any purchase agreement.
In Thailand, Stamp Duty is set at 0.5% of the registered or appraised value of the property - whichever is higher. Payment is due on the day of title transfer at the Land Department office. The critical detail: Stamp Duty is waived whenever the seller is liable for the Specific Business Tax (SBT) of 3.3%. These two charges are mutually exclusive - you will never pay both on the same transaction.
For a buyer purchasing a condominium priced at 10 million THB, Stamp Duty would equal 50,000 THB - but only if the seller has owned the property for more than five years. If the seller has held it for under five years, SBT applies instead, and Stamp Duty drops to zero.
Quick Answer
- Rate - 0.5% of the appraised or contracted value (whichever is greater)
- When paid - on the day of ownership transfer registration at the Land Department
- Trigger condition - Stamp Duty does NOT apply when SBT (3.3%) is in effect
- Who pays - legally the seller, but contracts frequently shift this cost to the buyer or split it 50/50
- Minimum threshold - none; the fee applies from the first baht
- Consequence of non-payment - the Land Department will not complete the transfer registration; the transaction cannot close
Scenarios and Options
Scenario 1: Buying from a Developer (New Build)
Developers selling primary units are almost always subject to SBT because they are classified as operating a business. As a result, Stamp Duty does not apply. The buyer typically covers half of the 2% Transfer Fee (1%), while the developer absorbs the SBT. Your Stamp Duty cost: zero.
Scenario 2: Secondary Market, Seller Owned Under 5 Years
A private individual who purchased a condo three years ago must pay SBT at 3.3%. Because SBT and Stamp Duty are mutually exclusive, Stamp Duty is again waived. Buyers should confirm in writing that SBT liability is clearly assigned to the seller within the purchase contract.
Scenario 3: Secondary Market, Seller Owned Over 5 Years
A private seller who has held title for six or more years is exempt from SBT. In this case, Stamp Duty of 0.5% applies. On a property valued at 15 million THB, that equals 75,000 THB. By default, the seller is liable, but contract terms can reassign this cost - make sure the agreement is explicit.
Scenario 4: Inheritance or Gift Transfer
Stamp Duty does not apply to inherited property. However, Thailand's Inheritance Tax applies at 5-10% on estates exceeding 100 million THB. Gift transfers between spouses or direct-line relatives attract a 5% gift tax above the 20 million THB exemption threshold. These are governed by separate mechanisms from the standard transfer process.
Scenario 5: Purchase via a Thai Company
When a Thai-registered legal entity acquires property, any subsequent resale typically triggers SBT (as the company is deemed to be conducting business). This means Stamp Duty on resale will again be zero. However, when a company buys land for its own operational use in a primary transaction, Stamp Duty may be assessed on the acquisition itself.

Main Risks and Mistakes
1. Failing to verify the seller's ownership date. This is the most consequential oversight. If a seller claims they have held the property for over five years but the title was re-registered at a later date (for example, after a land subdivision), SBT may apply unexpectedly instead of Stamp Duty. The cost difference can run into tens of thousands of baht. Always request the original title registration date from the Land Department.
2. Overlooking the Land Department's appraised value. Thailand's Land Department maintains its own official valuation for every parcel and building. If you purchase a unit for 8 million THB but the official appraisal is 10 million THB, Stamp Duty is calculated on 10 million THB - not the contract price.
3. Relying on verbal tax-sharing agreements. Thai law does not mandate any particular split of transfer costs. Everything is determined by the written contract. If the purchase agreement does not specify who pays Stamp Duty, the legal default assigns it to the seller - but sellers often price this into the asking figure. Get every tax allocation in writing before paying any deposit.
4. Confusing property Stamp Duty with lease stamp duty. Long-term lease agreements of three years or more that are registered at the Land Department carry a separate stamp duty of 0.1% applied to total rental payments over the lease term. This is an entirely different mechanism and should not be mixed up with the property transfer fee discussed here.
5. Underestimating Withholding Tax in the overall budget. Buyers often concentrate on Stamp Duty and overlook the seller's Withholding Tax obligation. For private sellers, this is calculated on a progressive scale and can represent a significant sum on high-value properties. This indirectly affects pricing and negotiating leverage, particularly in deals where the seller is seeking a net figure.
FAQ
Can Stamp Duty be paid in advance before the registration date? No. Payment is made directly at the Land Department on the day of the ownership transfer. There is no pre-payment mechanism.
Do foreign buyers pay a different Stamp Duty rate? No. The 0.5% rate is uniform for Thai nationals and foreign nationals alike. Your citizenship or residency status has no effect on the amount due.
Does the Thailand-Russia double taxation agreement cover Stamp Duty? The agreement covers income tax and corporate profit tax - not transfer fees or registration charges. Stamp Duty is a transactional registration payment and falls outside the scope of that treaty. The same applies to buyers from other countries with Thai tax treaties.
How can I calculate the exact Stamp Duty amount before signing? Ask your lawyer or agent to obtain the official Land Department appraisal value for the property. Take the higher of that figure and the contracted purchase price. Multiply by 0.5%. That is your Stamp Duty estimate.
Does Stamp Duty apply to land purchases? Yes. The same 0.5% rate applies when registering ownership of land, subject to the same SBT exclusion rule.
What happens if Stamp Duty is not paid? The Land Department will not register the transfer. There is no workaround - all applicable taxes and fees must be settled before title can be issued.
Is a condominium unit subject to Stamp Duty independently? Yes. Each condominium unit holds its own Chanote title deed and is assessed as a separate property. Stamp Duty is calculated individually for each unit.
Can furniture and fittings be separated from the property value to reduce Stamp Duty? If the purchase agreement clearly itemises furniture and equipment separately from the real estate value, the Land Department may accept a split calculation. This is a legal approach to cost optimisation but requires careful contract drafting by a qualified lawyer.
Is the rate different in Phuket compared to Bangkok? No. The 0.5% Stamp Duty rate is consistent across all provinces in Thailand. There are no regional surcharges.
Which is better for the buyer - a Stamp Duty or SBT scenario? From a pure cost perspective, Stamp Duty at 0.5% is lower than SBT at 3.3%. However, SBT is the seller's liability by default. The real impact depends on how costs are negotiated and allocated in the contract. A seller subject to SBT may push for a higher price to offset that liability, effectively passing it on indirectly.
Before signing any purchase agreement, request the seller's title registration date and obtain the Land Department appraisal for the property. These two figures determine whether you are in a Stamp Duty or SBT scenario - and they directly shape your total acquisition cost. On premium properties, the difference between the two tax regimes can reach hundreds of thousands of baht. Confirm all tax allocations in writing before any deposit changes hands.
