Thai Property Tax for Foreigners: Full 2026 Guide
By THAI.ESTATE Editorial Team15 min read
As a foreign buyer of Thai property, you pay tax at three moments: when you buy, while you hold, and when you sell. The amounts vary by property type, holding period, and whether the seller is an individual or a company. This guide covers every layer of the cost stack so you can budget accurately before you commit.
Quick answer
- Transfer fee: 2% of the registered value, split by negotiation (often 50/50 between buyer and seller)
- Specific Business Tax (SBT): 3.3% of the higher of appraised or sale price, paid by the seller if the property is held under 5 years or owned by a company - this cost is sometimes passed to the buyer by contract
- Stamp duty: 0.5% applies only when SBT does not apply - never both at once
- Withholding tax on purchase: deducted at source from the seller, but reduces the net you receive on a resale
- Annual land and building tax: low, typically 0.02%-0.1% of appraised value for residential use (as of 2026 Thai Revenue Department guidance)
- Rental income tax: withheld at source or self-assessed; non-residents typically face a flat withholding rate - verify the current rate with a Thai tax adviser
- Exit withholding tax: calculated on a sliding scale against appraised value and years of ownership; deducted at the land office at the point of transfer
Options and scenarios
What taxes do I pay when buying a condo in Thailand?
When title transfers at the land office, four charges are possible. Not all apply at once.
Transfer fee is 2% of the Department of Lands registered (appraised) value. The appraised value is often lower than the market price. Custom is to split this fee 50/50 between buyer and seller, but the split is negotiable and must be stated in the sale contract. On a THB 5 million appraised value, total transfer fee is THB 100,000 (roughly USD 2,700 at indicative 2026 rates).
Specific Business Tax (SBT) at 3.3% (including local tax) applies when the seller is a company, or when an individual seller has owned the unit for fewer than 5 years, or is not registered at that address in the household register. SBT is legally the seller's liability, but many developers and private sellers write it into the contract as a buyer's cost. Always check the contract clause.
Stamp duty at 0.5% applies only when SBT does not apply. The two are mutually exclusive. If SBT is due, stamp duty is waived.
Withholding tax (WHT) on the seller is deducted at the land office and paid to the Revenue Department at the moment of transfer. For individual sellers, the rate is calculated on a progressive scale based on appraised value and years held - it is not a flat figure. For corporate sellers, WHT is 1% of the higher of appraised value or sale price. This is the seller's cost, but again, contracts can shift the burden.
Worked indicative example - THB 5 million condo resale (as of 2026)
Assume:
- Buyer purchases a condo from an individual seller
- Department of Lands appraised value: THB 4,000,000
- Agreed sale price: THB 5,000,000
- Seller held the unit for 3 years (SBT applies, not stamp duty)
- Contract: transfer fee split 50/50, all other taxes are seller's responsibility
| Cost item | Rate basis | Calculated on | Amount (THB) | Paid by |
|---|---|---|---|---|
| Transfer fee (buyer's half) | 1% (half of 2%) | THB 4,000,000 appraised | 40,000 | Buyer |
| Transfer fee (seller's half) | 1% (half of 2%) | THB 4,000,000 appraised | 40,000 | Seller |
| Specific Business Tax | 3.3% | THB 5,000,000 (higher value) | 165,000 | Seller |
| Withholding tax | Progressive scale | Appraised value + years held | ~50,000-80,000 (indicative) | Seller |
| Stamp duty | Not applicable | SBT applies instead | 0 | - |
All figures are indicative. The withholding tax on the seller is shown as a range because it depends on the number of years held and the progressive rate table applied at the land office. Confirm exact figures with a Thai lawyer before signing.
Buyer's total transaction cost in this example: approximately THB 40,000 in government fees (transfer fee share), plus legal/due diligence fees (typically THB 15,000-50,000 depending on adviser). Total buyer-side cost: roughly 1-2% of purchase price in this scenario.
If the contract shifts SBT and WHT to the buyer, add THB 165,000 or more. Read every clause before signing.
What is the annual land and building tax for foreign-owned property?
Thailand introduced the Land and Building Tax Act, which replaced the old house and land tax and local development tax from 2020 onward. The tax is assessed on the Department of Lands appraised value, not the market price.
For residential property used as a primary residence by the owner, the rate is very low: 0.02% per year on values up to THB 50 million (as of 2026 guidance). For a condo appraised at THB 4,000,000, this means an annual tax of roughly THB 800 - a negligible amount.
For residential property not used as a primary residence (which covers almost all foreign-owned units, since foreigners cannot register a Thai household address in the same way), the rate rises to 0.02%-0.1% depending on the appraised value bracket. On a THB 4,000,000 appraised value, annual tax is indicatively THB 800-4,000 per year.
For property used for commercial or rental purposes, the land and building tax rate is higher. Verify the current rate with a local tax adviser, as brackets are subject to annual adjustment by the Ministry of Finance.
The local administrative organization (municipality or subdistrict authority) sends the annual assessment notice and collects the tax. Your juristic person office - the management company of your condominium building - can often assist with payment logistics.
What recurring fees do I actually pay as a condo owner?
The annual land and building tax is small. The real recurring costs for foreign condo owners are:
- Common-area management fee (CAM fee): charged per square metre per month, typically THB 30-80/sqm/month depending on building quality and location (market estimates, 2026). On a 50 sqm unit, this is roughly THB 1,500-4,000 per month.
- Sinking fund (a one-time or periodic capital reserve contribution used for major building repairs and capital works): often collected at initial purchase (THB 400-800/sqm is a common range for new builds, indicative figures) and sometimes topped up by special levy when the juristic person - the legal entity that manages the condominium building on behalf of all co-owners - votes for a major repair project.
- Utility bills: metered separately, often at slightly above residential rates inside condo buildings.
How is rental income from Thai property taxed for non-residents?
If you rent out a Thai property and you are not a Thai tax resident, rental income sourced in Thailand is subject to Thai income tax. For non-residents receiving rental income from a Thai property directly, the payer is generally required to withhold tax at source before remitting rent to you.
The withholding rate for non-resident individuals on rental income is subject to the provisions of any double-taxation agreement (DTA) between Thailand and your home country. Thailand has DTAs with over 60 countries (as of 2026). If a DTA applies, the DTA rate may be lower than the standard domestic rate. If no DTA applies, the standard non-resident withholding rate applies - verify the current rate with a Thai Revenue Department-registered tax adviser, as the applicable rate depends on your country of residence and the structure of the rental arrangement.
If you collect rent through a Thai company structure, company-level tax rules apply instead. This is a separate planning question requiring professional advice.
Practical note: Many foreign owners who rent informally do not register for Thai tax. This creates legal exposure. Thailand's Revenue Department has increased enforcement on rental income from condominiums, particularly in Phuket and Chiang Mai. Undeclared rental income can result in back-tax assessment plus penalties.
What taxes do I pay when selling Thai property?
At exit, the same four-charge framework applies, but now you are the seller:
- Transfer fee: 2% of appraised value (negotiated split as before)
- SBT or stamp duty: SBT at 3.3% applies if you hold the property under 5 years or own it through a company. Stamp duty at 0.5% applies if you have held it for 5 or more years as an individual.
- Withholding tax: calculated at the land office using a progressive rate table applied to the appraised value, divided by the number of years held. The land office issues a printed calculation. You do not negotiate this figure - it is a statutory formula. For individuals, this can range from under 1% to several percent of appraised value depending on the holding period and value bracket. It is deducted before you receive net proceeds.
A key point: withholding tax is calculated on the appraised value, not the price you actually agreed with the buyer. If you sell above appraised value, part of your gain is effectively tax-free at the land office level (though your home-country tax authority may take a different view).
Do I also owe tax in my home country?
Yes, almost certainly. Most countries tax their residents on worldwide income and capital gains, regardless of where the asset is located. If you are a tax resident of Germany, the UK, France, Australia, Singapore, the US or most other countries, you must declare Thai rental income and any gain on sale to your home tax authority.
Thailand has double-taxation agreements with many countries. A DTA generally prevents you from being taxed twice on the same income, but it does not eliminate your home-country filing obligation. The interaction between Thai withholding tax and your home-country tax credit system is complex. A tax adviser qualified in your country of residence is mandatory - this guide cannot substitute for that advice and deliberately does not give country-specific rates or rules.

Risks and mistakes
Accepting the developer's cost split without reading the contract. Many new-build contracts assign SBT and withholding tax to the buyer. On a THB 5 million unit, this can add THB 200,000 or more to your cost. Read the sale and purchase agreement clause by clause before signing.
Trusting appraised value as the total tax base. SBT and WHT use the higher of appraised value or sale price. If you pay above appraised value, the tax base is your actual purchase price. Budget accordingly.
Ignoring rental income tax. Thai enforcement on undeclared rental income has increased. Retroactive assessments can cover multiple years and include penalties and interest. Register with the Thai Revenue Department if you rent out your property.
Forgetting home-country tax obligations. Thai withholding tax does not discharge your home-country filing duty. Failure to declare can result in penalties in your home country that dwarf the Thai tax itself.
Misunderstanding the sinking fund. A sinking fund is a capital reserve, not a monthly fee. If the building requires a major repair (elevator replacement, roof waterproofing) and the reserve is inadequate, the juristic person can levy additional contributions from all co-owners. Budget for this contingency.
Relying on verbal assurances about tax splits. In Thailand, verbal agreements on cost allocation are not enforceable at the land office. The land office applies the law, not the contract between buyer and seller. Make sure the written sale contract reflects what you agreed.
Not verifying the DTA position. If your country has a DTA with Thailand, the withholding rate on rental income may be lower than the standard domestic rate. Claiming the DTA rate requires presenting the correct documentation (tax residency certificate). Not claiming it means you overpay.
FAQ
What is the total tax cost when buying a condo in Thailand as a foreigner?
In a typical resale transaction where the buyer pays only their half of the transfer fee, the buyer-side government cost is approximately 1% of the appraised value. If the contract shifts SBT (3.3%) and withholding tax to the buyer, the total can reach 4-5% or more of the sale price. Always identify which party pays which charge before you sign.
Do foreigners pay more property tax than Thai nationals?
No. Thai tax law does not impose higher rates on foreign individuals. The same transfer fee, SBT, stamp duty, and land and building tax rates apply to all individual buyers. The difference is that foreigners cannot always register a Thai household address, which means the residential primary-residence land and building tax exemptions are harder to access.
Is there a capital gains tax in Thailand?
Thailand does not have a separate capital gains tax. Instead, gains on property sales are captured through the withholding tax mechanism applied at the land office, calculated on the appraised value and years of ownership using a progressive rate table. The effective rate is lower than a pure capital gains tax in many cases, particularly for long holding periods.
How does the Specific Business Tax differ from stamp duty?
SBT (3.3%) and stamp duty (0.5%) are mutually exclusive. SBT applies when the seller is a company, or when an individual has held the property for fewer than 5 years, or is not listed on the household register at that address. Stamp duty applies only when SBT does not. You will never pay both on the same transaction.
Can the seller pass withholding tax costs to me as a buyer?
Legally, withholding tax is the seller's liability. However, sale contracts can and do shift this cost to the buyer. This is common in new-build developer contracts. Check every clause. If the contract says 'all taxes and fees shall be borne by the buyer', this likely includes SBT and withholding tax, which together can be substantial.
What happens if I rent out my condo without registering for Thai tax?
The Revenue Department can assess back taxes for up to 5 years on unreported income, plus a surcharge of 1.5% per month on unpaid tax and a penalty of 100% of the underpaid amount in some cases. With increased enforcement in tourist areas, the practical risk has grown since 2023.
Do I need to file a Thai tax return if tax is withheld at source?
For rental income where the payer withholds tax correctly, a tax return may not always be required, but it can allow you to claim deductions (standard expense allowances are available under Thai tax law) and recover overpaid tax. For most non-residents with Thai-source rental income, filing a Thai personal income tax return (PND 90 or PND 93 form) is advisable. A Thai tax adviser can confirm your specific obligation.
What is a juristic person in a Thai condominium?
A juristic person is the legal entity established under the Condominium Act to manage a registered condominium building. It collects common-area management fees and sinking fund contributions, oversees building maintenance, and acts on behalf of all co-owners. As a foreign condo owner, you are automatically a member of the juristic person. Your voting weight is proportional to your unit's share of total condominium space.
Are there any tax incentives for foreign property buyers in Thailand?
As of 2026, there are no specific tax incentives for foreign buyers of residential property in Thailand comparable to those in some other markets. The government has periodically reduced transfer fees and SBT as stimulus measures (for example, a temporary reduction was applied in 2020-2024 for properties under certain value thresholds), but these programmes are time-limited and subject to change. Verify whether any current stimulus applies at the land office or with a Thai property lawyer before your transaction.
How is withholding tax calculated at the land office when I sell?
The land office applies a statutory formula: it takes the appraised value, deducts a years-of-ownership expense allowance (a fixed percentage that increases with each year held), then divides the result by the number of years held to get an annual income figure, applies progressive income tax rates to that figure, and multiplies back by the years held. The land office staff run this calculation and present the result. You cannot negotiate the calculation, but you can ask for the printed breakdown to verify the arithmetic.
