Thailand Property Taxes for Foreign Investors: Full Guide with Numbers (2026)

A foreign buyer purchasing a condominium in Phuket for 10 million baht will pay between 200,000 and 650,000 baht in taxes and fees depending on how the transaction is structured. That is 2% to 6.5% of the purchase price. The gap is not random - it reflects how well the buyer understands the rules.

Thailand does not impose extra taxes on foreign buyers compared to Thai nationals. Rates are equal for everyone. But the payment structure is layered: five distinct charges at purchase, a progressive scale on rental income, and a separate regime at resale. This guide breaks down every element with real numbers.

Quick Answer

• Transfer Fee is 2% of the Land Department's assessed value
• Specific Business Tax (SBT) is 3.3% if the seller has owned the property for less than 5 years
• Stamp Duty is 0.5% of the higher of assessed or contract value, but only applies when SBT does not
• Withholding Tax on purchases from a juristic seller is 1% of assessed value
• Rental income tax for non-residents follows a progressive scale up to 35%, though a standard 30% expense deduction significantly reduces the effective rate
• Thailand has double taxation agreements (DTAs) with numerous countries, including agreements that allow foreign taxes paid in Thailand to be credited at home

Scenarios and Options

Buying a New Condominium from a Developer

This is the most common route for foreign buyers. The developer, as a juristic entity, pays Withholding Tax at 1% and typically covers a portion of the Transfer Fee. Market convention is to split the 2% Transfer Fee equally, meaning the buyer pays 1%. SBT at 3.3% usually falls on the developer.

For a unit priced at 10 million baht, the buyer's total outlay is approximately 100,000 baht (1% Transfer Fee) plus legal fees. Always read the contract carefully: some developers pass all transfer costs to the buyer.

Buying on the Secondary Market from an Individual

The structure shifts significantly here. If the seller has owned the property for fewer than 5 years, SBT at 3.3% applies. If ownership exceeds 5 years, Stamp Duty at 0.5% replaces SBT.

Withholding Tax for an individual seller is calculated on a progressive scale based on assessed value and years of ownership. The formula is complex: the assessed value is divided by the number of years held, the progressive rate is applied to that figure, and the result is multiplied back by the holding period.

In practice, for a 10 million baht property held for 3 years, the seller's Withholding Tax can reach 250,000 to 400,000 baht. While this is legally the seller's obligation, parties frequently negotiate who ultimately bears the cost.

Earning Rental Income

A foreigner renting out a condo in Thailand is required to pay personal income tax there. Under the Thai Revenue Code, rental income is taxed on a progressive scale:

• Up to 150,000 baht per year - exempt
• 150,001 to 300,000 baht - 5%
• 300,001 to 500,000 baht - 10%
• 500,001 to 750,000 baht - 15%
• 750,001 to 1,000,000 baht - 20%
• 1,000,001 to 2,000,000 baht - 25%
• 2,000,001 to 5,000,000 baht - 30%
• Above 5,000,000 baht - 35%

A key detail: landlords are entitled to a standard expense deduction of 30% without needing to submit supporting documents (or actual documented expenses if higher). This substantially reduces the effective rate.

Example: on annual rental income of 600,000 baht, applying the 30% deduction brings the taxable base to 420,000 baht. The resulting tax is approximately 19,500 baht - an effective rate of about 3.25%.

Selling the Property

When selling, a foreign individual pays Withholding Tax on a progressive scale (deducted at the Land Office), plus SBT at 3.3% if held for fewer than 5 years, or Stamp Duty at 0.5% for longer holding periods. Thailand does not impose a separate capital gains tax: the Withholding Tax effectively functions as the income tax on the sale proceeds.

Main Risks and Mistakes

1. Overlooking the Land Department's assessed value. Transaction taxes are calculated on the government's assessed value, not the contract price. This figure is frequently 20% to 40% below market value, which benefits the buyer. For new developments in prime locations, the gap may be much smaller.

2. Missing the Withholding Tax on corporate tenants. If a tenant is a Thai company or juristic entity, it is legally required to withhold 5% of the rent and remit it to the Revenue Department. This payment counts toward the landlord's annual tax liability - but many foreign owners never file a return and forfeit the right to reclaim any overpayment.

3. Not leveraging double taxation agreements. Thailand has DTAs with many countries. These agreements typically allow taxes paid in Thailand on property income to be credited against tax obligations in the investor's home country. Without proper tax planning, an investor risks paying tax twice on the same income.

4. Choosing the wrong ownership structure. Buying through a Thai company rather than holding a condo directly in freehold creates additional tax layers: corporate income tax at 20% on profits, plus dividend tax at 10% on distributions. The combined burden can exceed 28%, compared to an effective rate of 3-10% for an individual rental landlord.

5. Forgetting the annual Land and Building Tax. In effect since 2020, this tax applies to all property owners. For residential property valued under 50 million baht, the rate is a nominal 0.02% (200 baht per million). For vacant or unoccupied properties, the rate starts at 0.3% and increases every three years - making long-term vacancy costly.

FAQ

Does a foreigner need a Thai Tax ID to pay rental income tax? Yes. Filing a personal income tax return in Thailand requires a Thai Tax Identification Number (TIN). It is issued by the local Revenue Department office in a single visit, with a passport and proof of address.

What taxes does a freehold condo buyer actually pay at transfer? The primary buyer cost is the Transfer Fee of 2%, which is often split with the seller. SBT and Withholding Tax are formally the seller's obligations, though this is subject to negotiation.

Can VAT be reclaimed on a new condo purchase? No. VAT at 7% is embedded in the developer's price and is not recoverable by individual buyers as a separate refund.

How is rental income taxed for foreign nationals? Under the progressive scale from 0% to 35%, with a standard 30% expense deduction available. Taxes paid in Thailand can often be credited against tax obligations in the investor's home country under an applicable DTA - but this must be actively claimed, not assumed to apply automatically.

Is there an inheritance tax on Thai property? Yes, since 2016. Estates exceeding 100 million baht are taxed at 5% for direct heirs and 10% for others. For the vast majority of foreign investors, the threshold is unlikely to be relevant.

What is the tax on selling a condo after 7 years? With more than 5 years of ownership, SBT does not apply. The seller pays Stamp Duty at 0.5% and Withholding Tax on a progressive scale. The effective total rate typically falls between 1% and 3% of assessed value.

What happens if rental income is never declared? The Revenue Department can assess penalties of up to 200% of the underpaid tax, plus interest at 1.5% per month. Thai tax authorities have intensified scrutiny of foreign property owners in recent years. Non-filing is an increasingly visible and costly risk.

Does a DTA apply automatically? No. The investor must actively claim the foreign tax credit in their home country tax return, supported by documentation of taxes paid in Thailand. A tax adviser familiar with both jurisdictions is strongly recommended.

Thailand's property tax burden remains among the lowest in Asia. With proper transaction structuring, the total tax cost across purchase, ownership, and resale of a 10 million baht condo over a 5 to 7 year horizon can be kept well below 7% of the property value. The key is planning before signing, not after.
