Thai Property Tax for Foreigners: Full 2026 Cost Guide

As a foreign buyer, you pay four main layers of tax and fees when you own property in Thailand: transfer costs at purchase, annual land and building tax during ownership, income tax on rental earnings, and withholding tax when you sell. The exact amounts depend on the asset type, the declared value, how long the seller has held the property, and how the costs are split at the land office. This guide walks through every layer with indicative numbers so you can budget accurately before you commit.

Thailand has no capital gains tax as a separate category. Instead, gains on sale are captured through the withholding tax mechanism at the land office. There is also no annual wealth tax or property ownership surcharge for foreigners. What you do pay is a set of transaction taxes at entry and exit, plus a small recurring land tax each year.

Quick answer

• Transfer fee: 2% of the registered value, split by custom (often 50/50 between buyer and seller, but always negotiable)
• Specific Business Tax (SBT): 3.3% of the appraised or sale price (whichever is higher), paid by the seller if the property is sold within 5 years of acquisition
• Stamp duty: 0.5% of the registered value, applies only when SBT does not apply; not charged simultaneously with SBT
• Withholding tax on sale: calculated on a sliding progressive scale against the appraised value and the number of years held; paid by the seller at the land office
• Annual land and building tax: 0.02% to 0.7% of the official appraised value for most residential properties, capped at 0.3% for a foreign-owned condo used as a residence (as of 2026, under the Land and Building Tax Act B.E. 2562)
• Rental income tax: 15% flat withholding on gross rent paid to a non-resident, or progressive personal income tax rates if you are a Thai tax resident; verify the current rate with a licensed Thai accountant

Options and scenarios

What taxes do I pay when buying a condo in Thailand?

When ownership transfers at the land office, three charges apply. The transfer fee is 2% of the land office appraised value (not necessarily the sale price). Custom in the condo market is to split this 50/50, so you typically pay 1% and the seller pays 1%, but this is a commercial negotiation, not a legal rule. Always confirm in writing before signing the sale and purchase agreement.

The seller then pays either Specific Business Tax (SBT) or stamp duty, never both. SBT at 3.3% (3% tax plus 0.1% local tax) applies when the developer or any seller has held the property for fewer than five years. Stamp duty at 0.5% applies when the seller has held the property for five years or more, or if the seller is an individual (not a company) who has their name in the house register for the property. In practice, buying a new-build directly from a developer always triggers SBT. Buying a resale unit held for more than five years by an individual triggers stamp duty. Sellers typically absorb this cost, but again, it can be shifted by agreement.

Withholding tax (WHT) is deducted at source at the land office and is the seller's liability. It is calculated using the land department appraised value, the number of years the seller has owned the property, and a progressive personal income tax table. Because WHT reduces the seller's net proceeds, it can affect the agreed sale price in resale negotiations. As a buyer, you benefit from understanding it even though you do not pay it directly.

Worked numeric example at purchase (indicative, as of 2026)

Assume you buy a freehold condo unit in Chiang Mai with an agreed sale price of THB 5,000,000 (approximately USD 137,000 at indicative 2026 exchange rates). The land office appraised value is THB 4,200,000 (appraisal values often differ from market prices).

All figures below are indicative estimates based on published rates as of 2026. Actual amounts depend on the specific appraised value the land office assigns.

• Transfer fee: 2% x THB 4,200,000 = THB 84,000. If split 50/50, your share is THB 42,000
• SBT (developer/seller held less than 5 years): 3.3% x THB 5,000,000 (sale price is higher) = THB 165,000. Paid by seller, but you should be aware it affects negotiation
• Withholding tax (seller's liability): varies; for an individual seller, indicative range is THB 50,000 to THB 150,000 depending on years held and appraised value
• Your total land office cost: roughly THB 42,000 if you absorb only your half of the transfer fee
• Developer/agent fees: some projects charge a sinking fund (a one-time reserve for building repairs, typically THB 400 to THB 700 per sqm) and an advance common-area fee payment (typically 1 to 3 months). On a 45 sqm unit, sinking fund might be THB 22,500 at THB 500/sqm
• Legal due-diligence fee: a licensed Thai lawyer typically charges THB 15,000 to THB 50,000 for a condo purchase review; indicative market rates as of 2026

Indicative total buyer outlay above the purchase price: THB 80,000 to THB 120,000 on a THB 5,000,000 condo, representing roughly 1.6% to 2.4% of the purchase price

What do I pay each year while I own the property?

The Land and Building Tax Act B.E. 2562 (in force since 2020) replaced older house and land taxes. For a condo or house used as a primary or secondary residence, the annual rate on the official appraised value is:

• 0.02% on appraised value up to THB 50,000,000
• 0.03% on the portion from THB 50,000,001 to THB 75,000,000
• 0.05% on the portion above THB 75,000,000

For a property that is neither the owner's principal residence nor registered in a house register in the owner's name, the residential-investment rate applies, typically 0.02% to 0.1% (verify with your local municipality, as rates are set within statutory bands). Commercial use rates are higher, up to 0.3% to 0.7%.

On a condo with an appraised value of THB 4,200,000, the annual tax at 0.02% is approximately THB 840 per year. This is the smallest cost in the ownership lifecycle.

The larger recurring cost is the common-area maintenance fee (juristic person fee), which is not a government tax but is a mandatory contractual charge. A juristic person is the legal body that manages a condo building. Common-area fees in Thailand typically range from THB 30 to THB 80 per sqm per month as of 2026, per market estimates. On a 45 sqm unit at THB 50/sqm, that is THB 2,250 per month or THB 27,000 per year. This dwarfs the land and building tax.

How is rental income taxed for a foreign owner?

If you rent out your Thai condo and you are not a Thai tax resident (a tax resident is someone present in Thailand for 180 days or more in a calendar year), your rental income is subject to withholding tax at 15% on gross rent. Your Thai tenant or their employer deducts this and remits it to the Revenue Department. You receive the net amount. The 15% figure is the statutory rate as of 2026; verify the current rate before signing any lease agreement.

If you are a Thai tax resident, rental income is added to other Thai-source income and taxed at progressive personal income tax rates, ranging from 0% on income below THB 150,000 to 35% on income above THB 5,000,000. Allowable deductions exist (a standard 30% deduction on rental income, with a minimum deduction threshold; verify current rules with a Thai Revenue Department-licensed accountant).

Thailand has double-taxation treaties (DTTs) with over 60 countries, including most EU member states, the United Kingdom, the United States, and key Asian economies as of 2026. A DTT may reduce or eliminate the Thai withholding tax on rental income for residents of treaty countries, or allow a credit for Thai tax paid against your home-country tax bill. You must consult a tax adviser in your country of residence to understand how this applies to you. The THAI.ESTATE Editorial Team does not provide country-specific tax advice.

What taxes apply when I sell?

At the land office on the day of transfer, the seller (which will be you on exit) pays:

1. Withholding tax: calculated on the land office appraised value divided by the number of years held, then multiplied back. The longer you have held the property, the lower the effective rate, because the annual income figure is smaller and falls in lower progressive tax brackets. For a five-year hold on a THB 4,200,000 appraised condo, indicative WHT might be THB 60,000 to THB 100,000; treat this as a rough planning figure only and request a precise estimate from the land office or a licensed Thai accountant before the transaction
2. Transfer fee: again 2% of appraised value, negotiated with the buyer
3. SBT or stamp duty: if you have held the property fewer than five years and are not an individual with your name in the house register, SBT at 3.3% applies; otherwise stamp duty at 0.5% applies

There is no separate capital gains tax line. Your economic gain is implicitly captured through the withholding tax calculation, but because WHT is based on appraised value (not actual market gain), the effective tax on real gains can be very low in periods of strong price growth, or disproportionate in thin markets.

Risks and mistakes

Trusting the sale price declared at the land office. In some transactions, buyers and sellers agree to declare a price lower than the actual market price at the land office to reduce transfer fees and SBT. This is illegal. If the Revenue Department audits the transaction and finds evidence of the true price (through bank transfers, wire records, or foreign exchange transfer certificates - FET), both parties face penalties. Use the real price in all declarations.

Forgetting the FET certificate. A foreign exchange transfer certificate (FET), sometimes called a Thor Tor 3, is issued by a Thai bank when you bring foreign currency into Thailand and convert it to baht for a property purchase. For a condominium purchase, you need an FET to prove that funds came from abroad and to retain the right to repatriate sale proceeds later. Without it, taking money out of Thailand after a sale becomes very difficult. Request the FET from your Thai bank at the time of each inbound transfer.

Misunderstanding who pays what. Thai custom and Thai law are different things. Custom says the buyer and seller split the transfer fee 50/50. Law says the seller pays SBT or stamp duty and WHT. But all of these are negotiable unless a specific statute prevents it. New-build developers often write full buyer responsibility for all fees into their standard contracts. Read every line before signing.

Ignoring home-country tax obligations. Buying property abroad does not exempt you from declaring rental income or capital gains in your country of tax residence. Double-taxation treaties exist but must be actively invoked. Many buyers discover this only when they receive a tax authority inquiry at home several years into ownership. Get advice from a tax adviser in your own country before the purchase is complete.

Underestimating the common-area fee as a yield cost. On a THB 5,000,000 condo generating gross annual rent of THB 300,000 (6% gross yield), annual common-area fees of THB 27,000 reduce effective yield by nearly 1 percentage point before any other deductions. Factor this into yield calculations.

Using the wrong appraised value for planning. The land office appraised value (set by the Treasury Department and updated periodically) is often 20% to 40% below market value in high-demand areas. Some taxes are calculated on this lower figure (annual land tax, WHT), while SBT uses the higher of appraised value or actual sale price. This distinction materially changes cost estimates.

FAQ

Do foreigners pay more property tax than Thai nationals in Thailand?

No. Thailand does not apply different tax rates to foreign versus Thai owners of property. The same rates apply under the Land and Building Tax Act. The difference for foreigners is practical: you are more likely to be a non-resident for income tax purposes, which triggers the 15% flat withholding rate on rental income rather than the progressive resident rates.

Can I avoid Specific Business Tax by waiting 5 years before selling?

Yes. If you hold the property for more than five years as an individual, SBT does not apply and stamp duty at 0.5% applies instead. Additionally, if you register your name in the official house register (tabien baan) for the property, some individual sellers qualify for the stamp-duty route sooner. A licensed Thai lawyer can clarify whether this applies to your specific situation, property type, and ownership structure.

Is annual property tax in Thailand really as low as it seems?

For residential condos at typical foreign-buyer price points, yes. A condo appraised at THB 5,000,000 generates approximately THB 1,000 per year in land and building tax at the 0.02% rate. This is among the lowest residential property tax burdens in Southeast Asia. The meaningful recurring cost is the mandatory common-area fee, which is a private contractual charge, not a government tax.

What is an FET certificate and why does it matter for tax?

A foreign exchange transfer certificate (FET, sometimes Thor Tor 3) is a document your Thai bank issues when you receive foreign currency from abroad and convert it to Thai baht. For condo purchases, this document proves the purchase funds originated overseas, which is required under the Condominium Act for a foreigner to appear on the title deed (chanote - the highest-grade Thai land title, providing full ownership rights). The FET is also your proof of repatriation rights: when you sell, it allows you to send sale proceeds back overseas without special approval. Keep every FET on file.

Do I need to file a Thai tax return if I only earn rental income in Thailand?

If your rental income is subject to 15% withholding by your tenant, the tax is considered final and you may not need to file a return for that income. However, if you have other Thai-source income, or if you qualify as a Thai tax resident in any calendar year (present 180 days or more), filing obligations change. A Thai Revenue Department-licensed accountant should review your specific situation each year.

What happens to my tax position if I hold property through a Thai company?

Some foreign buyers use a Thai-registered company (typically a limited company) to hold property, which can offer access to land titles not available to foreign individuals. However, a company is a separate taxable entity. It pays corporate income tax on rental profits, and distributing profits to foreign shareholders triggers withholding tax on dividends. The total tax burden can be higher than individual ownership, and the legal structure must be maintained properly or it becomes invalid. This is a specialist area; consult a Thai lawyer and accountant before choosing this route.

Are there any property-related taxes Thailand has abolished that I might read about in older guides?

Yes. The House and Land Tax and the Local Development Tax were both abolished when the Land and Building Tax Act B.E. 2562 came into force in 2020. Any guide written before 2020 that mentions these taxes is outdated. Use only current sources and verify rates directly with the land office or a licensed professional.

How does the double-taxation treaty affect my rental income tax?

Thailand's DTTs generally allow the country of residence to tax worldwide income, while crediting taxes paid in Thailand. In practice, if your home country taxes rental income at a higher rate than 15%, you may owe the difference to your home tax authority after crediting the Thai WHT. If your home country rate is lower, you may still owe nothing more at home, but you need to claim the treaty benefit through the correct filing. The treaty mechanism varies by country. This is not something to handle without a qualified adviser in your home jurisdiction.
