Bangkok Property Buying Costs in 2026: 7 Fees Every Investor Must Know

Purchasing real estate in Bangkok involves a fee structure that surprises most international investors. There is no notary institution in Thailand in the sense familiar to buyers from continental Europe. The entire formal burden of transferring ownership falls on the Land Department, the government body responsible for property registration. Both buyer and seller sign documents at the Land Department office, where officials collect transfer fees on the spot. This creates a fundamentally different cost structure compared to markets where a notary intermediates every transaction.

A condominium purchase at 5,000,000 THB (approximately USD 140,000 at 2026 rates) generates total fiscal costs of 6-7% of the price when the seller has held the property for fewer than five years. If the seller has owned the unit for longer, combined costs can fall to 3-4%. The difference stems primarily from the specific business tax (SBT), which applies to shorter holding periods and replaces stamp duty in those cases.

Cambodia offers a simpler model: a flat 4% transfer tax on the assessed market value, plus an annual property tax of 0.1%. The absence of layered taxes makes budgeting more predictable, but legal certainty remains lower and no bilateral tax treaty exists between Cambodia and most European countries.

Quick answer

• Transfer fee in Thailand is 2% of the Land Department appraised value, customarily split 50/50 between buyer and seller
• Specific business tax (SBT) is 3.3% of the sale price, paid by the seller when the property has been held for fewer than 5 years
• Withholding tax applies to the seller at progressive rates from 5% to 35%, depending on income level and holding period
• Stamp duty of 0.5% is due only when SBT does not apply (holding period over 5 years)
• In Cambodia, the transfer tax is a flat 4% of assessed market value, paid by the buyer
• Rental income in Thailand is subject to progressive personal income tax at 5-35%; in Cambodia the rate is a flat 14%
• A double taxation treaty exists between Thailand and most investor home countries - always verify whether your country of residence has a treaty with Thailand or Cambodia before purchasing

Options and scenarios

Scenario 1 - Buying a new condominium in Bangkok from a developer

A developer sells a new unit at 5,000,000 THB. The transfer fee (2% of the Land Department appraisal) is conventionally split 50/50. The buyer pays approximately 50,000 THB. The developer covers its half of the transfer fee, pays SBT (3.3%), and handles withholding tax. The buyer additionally pays a one-time sinking fund contribution, typically 500-700 THB per square metre, and any mortgage processing fees if financing is involved.

Total buyer entry cost: approximately 1.5-2.5% of the purchase price.

Scenario 2 - Buying a resale condominium in Bangkok (seller held under 5 years)

The seller has owned the unit for three years. Transaction price: 5,000,000 THB. The seller is responsible for SBT (165,000 THB) and withholding tax (estimated at 50,000-100,000 THB at this holding period). The transfer fee of 100,000 THB is split, so the buyer contributes 50,000 THB.

Important: in secondary market transactions, cost-sharing is negotiable. Some sellers attempt to pass SBT liability to the buyer through contract clauses. Clarify this point with a qualified lawyer before signing any reservation agreement.

Scenario 3 - Buying an apartment in Phnom Penh, Cambodia

Purchase price: 100,000 USD. Transfer tax: 4%, equalling 4,000 USD, paid by the buyer. Annual property tax: 0.1% of value above 25,000 USD, roughly 75 USD per year. No SBT, no stamp duty, no withholding tax on the buyer's side.

Total buyer entry cost: 4-5%, inclusive of legal fees and document translation.

Scenario 4 - Rental income and cross-border tax filing

An investor rents out a Bangkok condominium at 25,000 THB per month. In Thailand, this income is subject to progressive personal income tax. Under applicable double taxation treaties (for example, Thailand has treaties with many EU countries, the UK, and the US), tax paid in Thailand can generally be credited against the investor's home-country tax liability. In practice, returns must be filed in both jurisdictions.

In Cambodia, rental income is taxed at a flat 14%. The absence of bilateral treaties with most European countries creates a risk of double taxation. Investors should seek specialist tax advice before committing capital.

Risks and mistakes

1. Seller shifting SBT to the buyer. In Bangkok resale transactions, some sellers insert contract clauses requiring the buyer to cover all taxes. In standard practice, SBT and withholding tax are the seller's obligations. Always have a lawyer review the reservation agreement before signing.

2. Undervalued Land Department appraisal. Transfer fees are calculated on the Land Department's assessed value, which is often below the actual transaction price. This is generally advantageous, but appraisals are updated periodically and revised values can increase the fee amount without warning.

3. Neglecting home-country tax obligations. Rental income from overseas property is taxable in most investor home countries. Failure to declare it can result in significant penalties. Consult a cross-border tax adviser who understands both jurisdictions before the first rent payment arrives.

4. Cambodia without a bilateral treaty. The absence of a double taxation agreement between Cambodia and most European countries means home-country tax authorities may tax the full income, allowing only limited credit for Cambodian taxes already paid. Obtain specialist advice before investing.

5. The Foreign Exchange Transaction Form (FETF). Foreign buyers of Thai condominium units must remit funds from abroad in a foreign currency and convert them at a Thai bank. The bank issues an FETF (also known as a Thor Tor 3 form). Without this document, the Land Department will refuse to register the title transfer. Wire transfers in local European currencies are not standard - USD or THB are most commonly used.

6. Confusing stamp duty with a notarial fee. In Thailand, stamp duty (0.5%) is a government transaction tax, not a professional service charge. There is no Thai equivalent of a notarial fee in the continental European sense. Ensure your transaction budget correctly categorises each line item.

FAQ

Does Thailand have a notary system like in continental Europe?

No. Thailand does not have a notary institution in the continental European sense. Property transfers are registered by the Land Department. Lawyers or law firms prepare documentation, but a Land Department official approves the transaction and collects fees on site.

How much is the transfer fee when buying a Bangkok condominium?

The transfer fee is 2% of the Land Department appraised value. It is customarily split equally between buyer and seller, though developers sometimes absorb the full amount as a promotional incentive.

Who pays specific business tax in Thailand?

The seller pays SBT of 3.3% of the sale price when the property has been held for fewer than five years. After five years, SBT no longer applies and stamp duty of 0.5% is levied instead.

Do I need to pay tax in my home country on rental income from a Bangkok property?

In most cases, yes. As a tax resident of your home country, you are typically required to declare foreign rental income in your annual tax return. If your country has a double taxation treaty with Thailand, tax paid there can generally be credited against your home-country liability using the proportional credit method. Confirm the applicable treaty rules with a qualified adviser.

How much does a property transfer cost in Cambodia?

The transfer tax in Cambodia is 4% of the assessed market value, paid by the buyer. An annual property tax of 0.1% of value above USD 25,000 also applies.

Does my home country have a double taxation treaty with Cambodia?

For most European and North American investors, no such treaty exists as of 2026. This creates a risk of double taxation on rental and capital gains income. Specialist tax advice is essential before investing in Cambodian real estate.

What is the FETF and why does it matter?

The Foreign Exchange Transaction Form (FETF), also called a Thor Tor 3, is a bank document confirming that funds for a Thai condominium purchase were remitted from abroad in a foreign currency. Without a valid FETF, the Land Department will not register the title transfer in a foreign buyer's name. This is a non-negotiable procedural requirement.

Can I deduct renovation or maintenance costs from rental income in Thailand?

In Thailand, individual taxpayers may deduct a standard allowance against rental income. The exact percentage depends on property type. In addition, personal allowances reduce taxable income. A Thai tax adviser can calculate the optimal deduction structure for your specific situation.

How high is the annual property tax in Bangkok?

Thailand introduced an annual property tax in 2020. For residential properties, the rate ranges from 0.02% to 0.1% of the Land Department appraised value. Commercial properties and undeveloped land can attract rates up to 0.3% or higher, depending on use and location.

What is the typical legal fee for buying a condominium in Bangkok?

Legal fees for a standard Bangkok condominium purchase typically range from 30,000 to 80,000 THB, covering due diligence, contract review, and Land Department representation. Always engage an independent lawyer rather than relying solely on the developer's legal team.
