Property Purchase Fees in Thailand and Cambodia: 7 Costs Every Investor Must Know in 2026

Buying a condominium in Bangkok priced at 5 million THB (approximately 130,000 USD) generates total transaction costs of between 6.3% and 8.5% of the purchase price in taxes and fees. The same budget deployed in Phnom Penh typically incurs costs closer to 4.5%. The gap reflects fundamentally different fiscal architectures - and in both cases, international investors must factor in their home-country tax obligations on top of local charges.

This guide breaks down every material fee with precise rates, worked numerical examples, and a clear indication of who actually bears each cost.

Quick answer

• Transfer fee in Thailand is 2% of the assessed value set by the Land Department - customarily split 50/50 between buyer and seller, though this is a convention, not a legal requirement
• Specific Business Tax (SBT) of 3.3% applies to the seller when the property has been held for fewer than 5 years
• Withholding tax in Thailand depends on the seller's status: progressive rates apply to individuals; a flat 1% applies to corporate sellers
• Stamp duty of 0.5% replaces SBT when the seller has held the property for more than 5 years
• In Cambodia, the property transfer tax is 4% of the market value, borne by the buyer
• Cambodia's annual property tax is 0.1% of value exceeding 100 million KHR (approximately 25,000 USD)
• Investors should verify their home-country tax treaty position with both Thailand and Cambodia before committing capital, as treaty coverage varies significantly between jurisdictions

Options and scenarios

Scenario 1: Secondary market condominium in Thailand - 5 million THB

You purchase a resale unit from an individual who has owned it for three years. The seller is subject to SBT.

• Transfer fee (2%): 100,000 THB total - with a 50/50 split, your share is 50,000 THB
• SBT (3.3%): 165,000 THB - borne entirely by the seller
• Withholding tax: calculated on the seller's taxable gain - not a direct buyer cost
• Land Office registration fee: a few hundred THB, negligible
• Sinking fund (one-time capital reserve contribution): 500 to 800 THB per sqm - on a 40 sqm unit, approximately 20,000 to 32,000 THB
• Common area management fee (monthly): 40 to 80 THB per sqm, equating to 1,600 to 3,200 THB per month

Total buyer-side cost at closing: approximately 70,000 to 82,000 THB one-time, plus ongoing monthly fees. This represents roughly 1.4% to 1.6% of the purchase price.

Scenario 2: Off-plan purchase from a developer in Thailand

On the primary market, developers typically absorb the transfer fee and SBT, embedding these costs in the listed price. The buyer's out-of-pocket at registration is largely limited to the sinking fund and the first instalment of common area fees. Always review the sale and purchase agreement carefully - some developers attempt to pass transfer fee liability to the buyer in the contract language.

Scenario 3: Condominium purchase in Phnom Penh - 100,000 USD

• Property transfer tax (4%): 4,000 USD - formally the buyer's obligation
• Annual property tax (0.1%): on a 100,000 USD unit, the taxable base above the exemption threshold generates approximately 75 USD per year
• Notarial and administrative fees: 200 to 500 USD
• Total acquisition cost: approximately 4,500 USD, or 4.5% of the purchase price

Rental income taxation

Thailand: Non-resident landlords are subject to a 15% withholding tax on gross rental income. In practice, many investors use professional property management companies that handle withholding at source. Investors from countries with a double tax treaty with Thailand can offset tax paid locally against their home-country liability, subject to the applicable treaty method.

Cambodia: Rental income for non-residents is taxed at 10%. Cambodia has limited double tax treaty coverage globally, which creates a risk of full double taxation for investors. Some jurisdictions allow a unilateral foreign tax credit, but the mechanics are less favourable than a bilateral treaty. Investors should obtain specific tax advice before structuring Cambodian rental income.

Important (2026 update): Thailand's rules on taxing foreign-sourced income remitted into Thailand in the year of earning were clarified in 2024. For non-Thai-tax-resident investors who do not remit rental proceeds to Thailand, this change has no direct impact on property acquisition costs.

Risks and mistakes

• Negotiating fee splits after signing the contract. Transfer fee allocation and all associated costs must be agreed in writing before the sale and purchase agreement is executed. The 50/50 convention in Thailand is a market norm, not statute - sellers can and do attempt to push the full 2% onto the buyer.

• Failing to verify the Land Department assessed value. Thai property taxes are calculated on the higher of the assessed (appraised) value or the transaction price. Assessed values are frequently 20% to 40% below market value, which can reduce the tax base - but buyers who assume the assessed value without verification risk surprises at the Land Office.

• Excluding sinking fund and common area fees from return calculations. In premium condominium projects, sinking funds can reach 1,000 THB per sqm. On a larger unit this is a material cash outflow at closing that must be modelled in the investment case.

• Ignoring home-country tax reporting obligations. Rental income earned abroad is typically taxable in the investor's country of residence. The existence of a double tax treaty reduces the risk of double taxation but does not eliminate the reporting requirement. Failure to declare foreign rental income is a compliance risk, not merely a tax optimisation question.

• Structuring Cambodian ownership through a local company without prior tax analysis. Using a Cambodian corporate entity changes the tax profile of rental income and capital gains materially. This approach requires a formal legal and tax opinion from advisors qualified in both the investor's home jurisdiction and Cambodian law.

• Underestimating foreign exchange risk. A transaction executed in THB or USD creates currency exposure when measured in the investor's home currency. On a 5 million THB purchase, a 5% exchange rate movement generates a cost or gain equivalent to several thousand USD - a figure that can dwarf the savings from fee negotiation.

FAQ

What is the transfer fee when buying a condominium in Thailand in 2026?

The transfer fee is 2% of the Land Department's assessed value of the property. By market convention, buyers and sellers split this 50/50, though the allocation can be negotiated and should be specified in the sale and purchase agreement before signing.

Who pays Specific Business Tax in Thailand?

SBT of 3.3% is the seller's liability and applies when the seller has owned the property for fewer than 5 years. If the holding period exceeds 5 years, SBT is replaced by stamp duty at 0.5%, which is also the seller's cost.

Is rental income from Thai property taxed twice for foreign investors?

Not necessarily. Thailand has double tax treaties with a number of countries, which typically allow investors to credit tax paid in Thailand against their home-country liability. The applicable method (exemption or credit) depends on the specific bilateral treaty. Investors should confirm treaty status and treaty method with a qualified tax adviser.

How much is the property transfer tax in Cambodia?

The transfer tax in Cambodia is 4% of the market value of the property and is formally borne by the buyer. Administrative and notarial fees add approximately 200 to 500 USD on top of this charge.

Does Cambodia have a broad double tax treaty network?

No. Cambodia has a limited number of double tax treaties in force globally. Investors from countries without a bilateral treaty with Cambodia face a higher risk of double taxation on rental income. Some jurisdictions permit a unilateral foreign tax credit, but the process is more complex and less certain than treaty-based relief.

What is the sinking fund in a Thai condominium purchase?

The sinking fund is a one-time capital contribution to the condominium's maintenance reserve, paid at the time of unit transfer. Standard rates range from 500 to 800 THB per sqm, with premium developments charging up to 1,000 THB per sqm. On a 40 sqm unit at mid-range rates, this amounts to 20,000 to 32,000 THB.

What are the annual property taxes on a Thai condominium?

Thailand's land and building tax applies on a progressive scale from 0.02% to 0.3% of assessed value, depending on property use (residential, commercial, agricultural, or vacant). Owner-occupied residential properties attract the lowest rates. The annual liability on a typical investor-owned condominium is modest but should be budgeted.

Does a Thai developer cover the buyer's closing costs?

On the primary (off-plan) market, most developers absorb transfer fee and SBT, incorporating these costs into the listed price. The buyer typically pays the sinking fund and an initial common area fee instalment. Review the sale and purchase agreement explicitly - some contracts shift transfer fee liability to the buyer despite market convention.

What legal due diligence fees should I budget in Thailand?

Independent legal review (title due diligence, contract review, Land Office accompaniment) typically costs between 30,000 and 80,000 THB depending on transaction complexity. For transactions above 200,000 USD equivalent, engaging qualified independent legal counsel is strongly recommended.

What is a common area fee in Thai condominiums?

The common area fee (CAF) is a recurring monthly charge covering building management, shared facilities maintenance, security, and utilities for common spaces. Rates typically range from 40 to 80 THB per sqm per month. On a 40 sqm unit this equates to 1,600 to 3,200 THB per month - a recurring cost that directly affects net rental yield calculations.
