Bangkok Property Buying Costs in 2026: 7 Fees Every Investor Must Know
Thailand does not have a notary system in the European sense. The Land Department serves as the official registration authority, and transaction costs are distributed across several distinct government fees and taxes. For any international investor purchasing a condominium in Bangkok, this means one thing: you need to understand the structure of seven core charges before signing a reservation agreement.
The price you pay to the developer or seller is only the starting point. Depending on whether you are buying a new unit from a developer or a resale property, total transaction costs range from 1.1% to as much as 6.3% of the sale price. The difference is significant and stems directly from Thailand's Revenue Code and Cambodia's tax regulations.
Quick answer
- Transfer fee: 2% of the official appraised value, typically split equally between buyer and seller
- Specific Business Tax (SBT): 3.3% of the sale price or appraised value (whichever is higher), charged to sellers who have held the property for less than 5 years
- Stamp duty: 0.5%, applied only when SBT does not apply
- Withholding tax: depends on the seller's status, individuals pay on a progressive scale, companies pay 1%
- Rental income tax in Thailand: progressive rates up to 35% for individuals; no annual property tax for residential units valued below 50 million THB
- Foreign buyers must obtain a Thor Tor 3 form (FETF): proof that funds arrived from abroad in foreign currency, required for Land Department registration
- No double taxation treaty between Cambodia and most Western countries: for Cambodia, investors must rely on unilateral relief provisions in their home jurisdiction
Options and scenarios
Scenario 1: Buying a new condominium from a developer in Bangkok
You purchase an apartment priced at 5,000,000 THB (approximately 130,000 USD) from a primary-market developer. In practice, most Bangkok developers absorb the transfer fee and applicable taxes as a buyer incentive. Your out-of-pocket costs are limited to:
- Sinking fund: a one-time payment of approximately 500-700 THB per square metre
- Utility meter deposits (water and electricity): 20,000-40,000 THB
- First annual common area fee: 40-80 THB per square metre per month
Total additional cost above the purchase price: approximately 1.1-1.5%.
Scenario 2: Buying a resale condominium in Bangkok
You purchase the same unit at 5,000,000 THB from a private seller who has owned it for less than 5 years. The standard cost allocation looks like this:
- Transfer fee 2%: 100,000 THB, split equally (50,000 THB per party)
- Specific Business Tax 3.3%: 165,000 THB, borne by the seller
- Withholding tax: calculated on a progressive scale, typically 75,000-150,000 THB, borne by the seller
As the buyer, your realistic direct cost is 50,000 THB (1% of price) plus standard administrative charges. Note that on the secondary market, cost allocation is a negotiation point. In some transactions, the buyer absorbs the full transfer fee in exchange for a lower headline price.
Scenario 3: Buying a condominium in Phnom Penh, Cambodia
For comparison: you purchase an apartment in Phnom Penh at 100,000 USD. The fee structure is more straightforward but more expensive for the buyer:
- Property transfer tax: 4% of the property value, 4,000 USD, paid by the buyer
- Annual property tax: 0.1% of value exceeding approximately 25,000 USD threshold, in practice, a few tens of dollars annually
- Legal and registration fees: 1,000-2,500 USD
Total transaction cost for the buyer: approximately 5-6.5% of the purchase price, materially higher than a new Bangkok condominium.

Rental income taxation
Thailand
Rental income from Thai property is taxable on a progressive scale ranging from 5% to 35%. If you are not a Thai tax resident (present fewer than 180 days per year in Thailand), new rules introduced in recent years have expanded the Revenue Department's scope: funds transferred into Thailand are now taxable regardless of the year in which the income was originally earned.
In practice, many foreign property owners settle their Thai tax obligations through their property management agent, who withholds 5% withholding tax from gross rental receipts.
Cambodia
Rental income in Cambodia is subject to income tax. An additional rental tax of 10% of gross rent applies when annual rental income exceeds specified thresholds. Investors should factor both charges into their yield calculations from the outset.
International tax obligations for home-country residents
Most countries tax their residents on worldwide income, including rental income and capital gains from overseas property. International investors should confirm how their home country treats Thailand and Cambodia property income before completing a purchase.
For investors from countries with a bilateral double taxation treaty with Thailand, the standard method is a credit for tax paid in Thailand against home-country liability, subject to proportional limits. For Cambodia, where bilateral treaties are less common, investors may need to rely on unilateral relief provisions. In both cases, professional tax advice from a specialist in cross-border taxation is strongly recommended.
Risks and mistakes
Understated official appraisal values: The Land Department uses its own valuation tables. If the agreed transaction price exceeds the official appraised value, SBT is calculated on the higher transaction price. Do not attempt to suppress the stated price in the contract, this constitutes a tax offence under Thai law.
Overlooking currency conversion costs: International wire transfers from your home country to a Thai bank account carry bank spreads and potential fees. Currency conversion costs can reach 1-2% of the total amount. Specialist foreign exchange platforms typically offer significantly better rates than retail banks.
Missing the Foreign Exchange Transaction Form (FETF, Thor Tor 3): As a foreign buyer, you must demonstrate that purchase funds arrived from abroad in a foreign currency. Your Thai bank issues this document, known as Thor Tor 3. Without it, the Land Department will not register the property in your name.
Ignoring sinking fund and common area fees in yield calculations: These are not one-off costs. The common area fee is a fixed monthly expense of 40-120 THB per square metre. For a 50 sqm apartment, that is 2,000-6,000 THB per month, a direct reduction to your net rental yield.
Exceeding the foreign ownership quota: Foreign nationals may collectively own a maximum of 49% of the total floor area in any given condominium building. If the foreign quota is exhausted, the transaction cannot proceed. Always verify quota availability before signing any agreement.
Skipping independent legal due diligence: Never rely solely on the seller or developer for information on fee allocation. Engage an independent Thai property lawyer for due diligence, typically 30,000-80,000 THB, to verify title, review the sale and purchase agreement, and confirm that all charges are transparently documented.
FAQ
Does Thailand have notary fees like European countries?
No. Thailand does not have a notarial system equivalent to those in continental Europe. The Land Department functions as the registration authority, and the primary costs are the transfer fee (2%), Specific Business Tax (3.3%) or stamp duty (0.5%), and withholding tax. There is no separate notarial tariff.
Who pays the transfer fee when buying a Bangkok condominium?
On the primary market, developers typically absorb the 2% transfer fee as a buyer incentive. On the secondary market, the standard arrangement is a 50/50 split between buyer and seller, though this is always subject to negotiation and should be clearly stated in the sale and purchase agreement.
How much is the property transfer tax in Cambodia?
The property transfer tax in Cambodia is 4% of the property value, paid by the buyer. Legal and registration fees add a further 1,000-2,500 USD on top of this.
Do I need to pay tax in my home country on rental income from a Bangkok apartment?
In most countries, yes. Tax residents are generally required to declare worldwide income, including overseas rental income. Where a bilateral double taxation treaty with Thailand exists, you can typically credit tax paid in Thailand against your home-country liability using a proportional credit method. Confirm the specific rules with a qualified international tax adviser.
Does my country have a tax treaty with Cambodia?
Cambodia has signed relatively few bilateral double taxation treaties. Investors from most Western countries will need to rely on unilateral domestic relief provisions. Specialist international tax advice is essential before investing in Cambodian property.
What is the Thor Tor 3 form (FETF) and why does it matter?
The Thor Tor 3, or Foreign Exchange Transaction Form (FETF), is a document issued by a Thai bank confirming that funds used to purchase a condominium were remitted from abroad in a foreign currency. Without this document, the Land Department will refuse to register the property in a foreigner's name. It is a mandatory step in any foreign condominium purchase.
What is the annual property tax rate in Thailand?
For residential properties valued below 50 million THB (approximately 1.4 million USD), the effective rate is 0%. Above this threshold, progressive rates from 0.02% to 0.1% apply. The vast majority of foreign investor purchases fall well within the zero-rate band.
What are the hidden costs of buying a Bangkok condominium?
The most frequently overlooked costs are: sinking fund (500-700 THB per sqm, one-off), common area fee (40-120 THB per sqm per month), utility meter deposits (20,000-40,000 THB), independent legal due diligence (30,000-80,000 THB), and currency conversion costs (1-2% of the transferred amount).
Can Specific Business Tax and stamp duty apply at the same time?
No. If the seller is liable for Specific Business Tax (3.3%), stamp duty (0.5%) does not apply. Stamp duty is charged only when the seller has held the property for more than 5 years and is therefore exempt from SBT.
What is the foreign ownership quota for Thai condominiums?
Foreign nationals may collectively own a maximum of 49% of the total floor area in any single condominium building. This limit is set by the Thai Condominium Act. If the quota is already at capacity, a foreign buyer cannot take freehold ownership and would need to consider alternative structures, which carry different risk profiles.
