Property Taxes in Thailand for Foreign Buyers: 7 Payments You Need to Know

A foreign buyer purchasing a condominium in Phuket for 10 million THB can expect to pay between 200,000 and 650,000 THB in taxes and fees at the point of transfer — depending on whether the seller is an individual or company, and how long they have held the property. That figure does not include annual ownership costs or rental income tax.

Thailand does not impose higher tax rates on foreign buyers compared to Thai nationals. The rates are identical. What confuses most international investors is the structure: some fees are paid by the buyer, some by the seller, and some are split by negotiation. Without a clear understanding of this framework, you can easily lose 3–6.5% of the property value without realising it.

Quick Answer

• Transfer Fee — 2% of the Land Department assessed value, paid at registration

• Specific Business Tax (SBT) — 3.3% of the assessed or actual sale price (whichever is higher), applies when the seller has owned the property for fewer than 5 years

• Stamp Duty — 0.5% of assessed or sale price, applies only when SBT does not

• Withholding Tax — calculated on a progressive scale from 0% to 35% for individual sellers; withheld at the Land Department during registration

• Rental Income Tax — non-residents are subject to a 15% flat withholding on gross rental income; tax residents file an annual return under the progressive Personal Income Tax (PIT) schedule

• Land and Building Tax — an annual levy ranging from 0.02% to 0.3% depending on property use and assessed value

• Inheritance Tax — 10% on estates exceeding 100 million THB in value (applies to non-residents)

Scenarios and Options

Scenario 1: Buying a New Condominium from a Developer

Developers typically absorb the Specific Business Tax and the Transfer Fee — or at minimum split the Transfer Fee with the buyer. The effective tax burden for the buyer in this scenario is usually around 1% of the purchase price. This makes off-plan and new-build purchases significantly more cost-efficient at the point of entry.

Scenario 2: Buying Resale Property — Seller Owned Less Than 5 Years

This is the most expensive configuration. The combined tax load includes Transfer Fee at 2%, SBT at 3.3%, and Withholding Tax calculated on a progressive scale. The total can reach 6.3–8% of the property value. How costs are split is subject to negotiation. Market convention typically sees the Transfer Fee divided equally, with the seller covering SBT and Withholding Tax — but nothing is automatic. Always confirm the allocation in the Sale and Purchase Agreement.

Scenario 3: Buying Resale Property — Seller Owned 5 Years or More

SBT does not apply. In its place, the seller pays Stamp Duty at 0.5%. This significantly reduces the total tax burden, which typically falls in the range of 3–5% of the property value. Long-held resale properties often represent better value from a transaction cost perspective.

Scenario 4: Rental Income

Rental income from Thai property is subject to Thai Personal Income Tax. If a foreign national spends 180 days or more in Thailand during a tax year, they are classified as a tax resident and must declare worldwide income earned in Thailand.

The PIT progressive schedule runs from 0% (on income up to 150,000 THB) to 35% (on income exceeding 5 million THB), as published by the Thailand Revenue Department.

From 1 January 2024, Thailand revised its rules on foreign-sourced income: funds remitted to Thailand are now taxable in the year they are received — regardless of when the income was originally earned. This is a critical change for property investors who receive offshore rental income or transfer funds from abroad.

For non-residents, the standard withholding on gross rental payments is 15%, deducted by the tenant or property management company at source. However, filing an annual return may reduce this effective rate — Thailand allows a standard 30% expense deduction on gross residential rental income before applying the PIT rate.

Scenario 5: Double Taxation Agreements

Thailand has signed Double Taxation Agreements (DTAs) with over 60 countries, including the UK, Germany, Australia, Singapore, and many others. These agreements generally provide that rental income from Thai property is taxable in Thailand. Taxes paid in Thailand can be credited against the investor's home-country tax liability — though the credit is capped at the amount calculated under the home country's own tax rate. DTAs do not eliminate taxation; they prevent the same income from being taxed twice in full.

Investors should consult a qualified tax adviser familiar with both Thai and their home-country tax law before structuring ownership or income flows.

Main Risks and Mistakes

1. Understating the contract price. The Land Department compares the declared sale price against its own assessed value. If the declared price is lower, taxes are calculated on the assessed value — not the contract price. Understating the price does not save money and creates complications at resale.

2. Overlooking Withholding Tax in resale negotiations. Buyers sometimes fail to account for the possibility that Withholding Tax could be shifted to them during negotiations. Always fix the tax allocation in writing within the Sale and Purchase Agreement before signing.

3. Not filing an annual return when renting out property. Even when a management company withholds 15% at source, filing a return as a tax resident can reduce the effective rate through the 30% expense deduction. This is frequently overlooked, especially by part-time residents.

4. Ignoring the 2024 foreign income rule. If you are a Thai tax resident and transfer funds into Thailand — whether rental income, proceeds from property sales, or other receipts — those funds are now taxable in the year of remittance. Plan accordingly.

5. Misunderstanding how DTAs work. A treaty does not exempt you from Thai tax. It allows a credit against your home-country liability. Without professional advice across both jurisdictions, the credit mechanism is easily misapplied.

6. Not registering for a Thai Tax Identification Number (TIN). A Thai TIN is required to file tax returns, claim deductions, and maintain proper compliance. The registration process takes 1–2 working days at the local Revenue Department office and is free of charge.

FAQ

Do foreign buyers pay higher tax rates than Thai nationals?

No. Tax rates on property transactions and rental income are identical for Thai nationals and foreign buyers. The key distinction for foreigners lies in ownership rights: a foreign individual can hold a condominium under freehold title (within the 49% foreign quota), but cannot directly own land.

How much should I budget for taxes when buying a new condo from a developer?

Typically 1–2% of the purchase price for the buyer. Developers assume the major tax costs as part of their sales structure. Always confirm the exact allocation in the contract before signing.

Is there an annual property tax in Thailand?

Yes. The Land and Building Tax, in force since 2020, applies to all property. For residential property valued at up to 50 million THB, the rate is 0.02% per year. On a 10 million THB condominium, this amounts to approximately 2,000 THB annually — a minimal ongoing cost.

How is rental income taxed for non-residents?

If you do not qualify as a Thai tax resident (fewer than 180 days in Thailand during the tax year), the tenant or property management company is required to withhold 15% of gross rental payments at source. No annual return is mandatory, but filing one may yield a refund through the 30% expense deduction.

What is Withholding Tax and who pays it?

Withholding Tax is a personal income tax deducted from the seller at the point of registration at the Land Department. It is formally the seller's liability, calculated using the progressive PIT schedule on a deemed gain basis — but the allocation between buyer and seller is negotiable and must be clearly stated in the agreement.

Is resale of a condominium taxable?

Yes. When selling, the seller is subject to Withholding Tax in all cases. If they have owned the property for fewer than 5 years, SBT at 3.3% also applies. For ownership periods of 5 years or more, SBT is replaced by Stamp Duty at 0.5%.

How do I register for a Thai Tax Identification Number?

Visit your local Area Revenue Office in person with your passport, proof of property ownership or lease, and (if applicable) a work permit. The process is free and typically completed within 1–2 business days.

Do I need an accountant to file a Thai tax return?

Not legally — the annual return (Form PND 90 for individuals with multiple income sources) can be filed online via the Thailand Revenue Department portal. However, for rental income or property sale proceeds exceeding 1 million THB, engaging a licensed Thai tax accountant is strongly recommended. Fees typically range from 5,000 to 15,000 THB.

---

The key takeaway for any international buyer: before signing any agreement, obtain a full tax calculation covering the purchase transaction, ongoing ownership, and potential resale. Fix the allocation of all taxes and fees between buyer and seller explicitly in the contract. And register for a Thai TIN as soon as the purchase completes — it is the foundation of proper tax compliance and access to deductions.
