All Property Transaction Taxes in Thailand: Complete Checklist 2026
A buyer purchasing a Phuket condo for 8 million baht expected to pay only the agreed price. At the land office on closing day, an additional 412,000 baht appeared in fees, taxes, and duties. Nearly 5% on top of the purchase price. This scenario plays out every week across Thailand.
Thailand imposes at least three categories of mandatory payments on every property transaction: a transfer registration fee, either a Special Business Tax or Stamp Duty, and a withholding tax on the seller. For foreign buyers, rental income taxation and international tax treaty rules add further complexity. Below is a precise breakdown of every cost element, with exact rates, calculation formulas, and the most common mistakes to avoid.
Quick Answer
- Transfer Fee - 2% of the Land Department appraised value
- Special Business Tax (SBT) - 3.3% of the appraised or contract price (whichever is higher), applied when the seller has held the property for fewer than 5 years
- Stamp Duty - 0.5% of the appraised or contract price, applicable only when SBT does not apply
- Withholding Tax - deducted from the seller; fixed at 1% for corporate sellers, calculated on a progressive scale for individuals
- Rental income for foreign owners is taxed on a progressive scale from 0% to 35%
- Total transaction costs on a typical deal range from 3.3% to 6.3% of the property value
Budget at least 5 to 7% above the contract price to cover all fees, taxes, and legal services without surprises.
Scenarios and Options
Scenario 1 - Buying a New Condo from a Developer
When purchasing a unit in a new or recently completed project, costs are typically shared. The developer absorbs half of the Transfer Fee (1%) as a standard marketing incentive, while the buyer pays the remaining 1%. SBT and Withholding Tax fall entirely on the developer as the selling party.
Example: a studio purchased for 5,000,000 baht in a new Phuket condominium. The buyer's direct transaction cost is approximately 50,000 baht for the Transfer Fee share, plus a one-time Sinking Fund contribution and Common Area maintenance fees upon handover. Total additional outlay: roughly 150,000 to 200,000 baht above the unit price.
Scenario 2 - Buying a Resale Condo from an Individual Seller
The allocation of costs is subject to negotiation. Thai law assigns the Transfer Fee to the buyer and transaction taxes to the seller, but a 50/50 split across all charges is widely practiced in the resale market.
Example: a condo purchased for 8,000,000 baht, seller held for 3 years. Land Department appraised value: 7,200,000 baht.
- Transfer Fee: 2% of 7,200,000 = 144,000 baht
- SBT: 3.3% of 8,000,000 (contract price is higher) = 264,000 baht
- Withholding Tax on individual seller: calculated on a progressive scale, estimated 120,000 to 180,000 baht depending on years of ownership
- Total transaction costs: 528,000 to 588,000 baht, roughly 6.6% to 7.4% of the purchase price
Scenario 3 - Buying a Villa via Leasehold Structure
Foreigners cannot own land freehold in Thailand. One legally recognized alternative is a 30-year land lease (leasehold), with the building structure registered separately to the foreign buyer under a right of superficies.
When registering a leasehold, the applicable costs are a registration fee of 1% of the total lease value and Stamp Duty of 0.1% of the total lease value.
Example: total lease value over 30 years is 3,000,000 baht. Registration costs: 30,000 + 3,000 = 33,000 baht - a comparatively low transaction cost relative to freehold transfers.
Scenario 4 - Rental Income for Foreign Property Owners
Foreign nationals receiving rental income from Thai property are required to pay personal income tax. The rates follow a progressive scale:
- Up to 150,000 baht/year - 0%
- 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 benefit: landlords may deduct a standard 30% expense allowance from gross rental income (residential property) without providing supporting receipts. This deduction significantly reduces the taxable base and the resulting liability.
Comparison Table - Transaction Costs by Property Type
| Parameter | New Developer Unit | Resale (held under 5 yrs) | Resale (held over 5 yrs) | Leasehold Land |
|---|---|---|---|---|
| Transfer Fee | 2% (typically split 50/50) | 2% (by negotiation) | 2% (by negotiation) | 1% of lease value |
| Special Business Tax (3.3%) | Paid by developer | Paid by seller | Not applicable | Not applicable |
| Stamp Duty (0.5%) | Not applicable when SBT applies | Not applicable when SBT applies | 0.5% paid by seller | 0.1% of lease value |
| Withholding Tax | Paid by developer | Progressive scale on seller | Progressive scale on seller | Not applicable |
| Buyer's direct cost | 1% to 1.5% | 1% to 3.3% | 1% to 1.5% | 1.1% |
| Total deal cost | 3.3% to 4.5% | 5.3% to 6.8% | 3% to 4% | 1.1% |
Main Risks and Mistakes
1. Misunderstanding appraised value vs. contract price. The Land Department maintains its own appraised value database, which is often below market price. However, both Transfer Fee and SBT are calculated on whichever figure is higher - the appraised value or the contract price. Deliberately understating the contract price constitutes tax fraud and can result in substantial penalties and criminal liability.
2. Miscounting the 5-year SBT threshold. The five-year ownership period is measured from the date of registration at the Land Department - not from the date a purchase contract was signed. Sellers regularly confuse these two dates and find themselves unexpectedly liable for the full 3.3% SBT.
3. Overlooking double taxation treaty provisions. Thailand has double taxation agreements (DTAs) with numerous countries, including the United Kingdom, Australia, Singapore, Germany, and others. Rental and property income taxed in Thailand may be credited against tax obligations in the investor's home country. Note that since 2024, Thailand taxes income remitted into the country in the same tax year it is earned. Consult a qualified tax advisor in both jurisdictions before structuring your investment.
4. Forgetting the Sinking Fund. This is not a tax, but it is a mandatory one-time payment due at handover for condo units - typically 400 to 800 baht per square metre. On a 45 sqm apartment, that amounts to 18,000 to 36,000 baht and is often overlooked in early cost estimates.
5. Underestimating Withholding Tax complexity for individual sellers. The calculation formula is layered: the appraised value is divided by the number of years of ownership, a progressive rate is applied to the resulting annual figure, and the tax is then multiplied back by the number of years. The Land Department officer performs this calculation on closing day. Request a preliminary estimate from your legal advisor before signing any contract.
6. Missing the foreign exchange documentation requirement. For a foreign national to register a condominium unit in their name, the Land Department requires proof that purchase funds were remitted from abroad in foreign currency. This proof takes the form of a Thor.Tor.3 form (Foreign Exchange Transaction Form), issued by a Thai bank. Without this document, registration will be refused. The declared amount must match the purchase price.
FAQ
Who pays the Transfer Fee - buyer or seller? Under Thai law, the Transfer Fee is the buyer's responsibility. In practice, resale transactions often involve a 50/50 split by mutual agreement. Developers frequently absorb half or the full Transfer Fee as a promotional incentive.
Do foreign buyers pay higher taxes than Thai nationals? No. Tax rates are identical for residents, non-residents, Thai nationals, and foreigners. The procedural difference is that foreign buyers must present the Thor.Tor.3 foreign exchange form, and for condominiums, they must confirm the building's foreign ownership quota has not been exceeded (foreigners collectively may not own more than 49% of total floor area in any condominium building).
Is capital gains tax applied when selling a property? Thailand does not have a standalone capital gains tax. Profit from a sale is factored into the Withholding Tax and SBT calculations. In practice, these taxes are assessed on the full appraised or contract value rather than solely on the profit margin between purchase and sale prices.
Do I need to file a tax return if I rent out my property? Yes. Rental income received in Thailand must be declared on form PND 90, filed by 31 March of the following year. The penalty for non-filing is up to 2,000 baht, plus monthly interest of 1.5% on any unpaid tax.
Is there an annual property holding tax in Thailand? Yes. Thailand's Land and Building Tax, introduced in 2020, applies annually. For owner-occupied residential property valued under 50 million baht, the rate is 0.02% of the appraised value per year. Property rented out or left vacant attracts higher rates, ranging from 0.02% to 0.1% depending on use and value tier.
Can I pay with cryptocurrency and simplify the tax process? No. The Land Department requires documented proof of a legitimate overseas bank transfer. Cryptocurrency payments do not satisfy the Thor.Tor.3 requirement. Additionally, converting cryptocurrency to Thai baht through a local exchange creates a separate taxable event under Thai revenue law.
What happens if the contract price is understated? The Land Department cross-references the declared contract price against its own appraised value database. A significant discrepancy invites scrutiny. Tax authorities may reassess and impose additional charges, and in serious cases, formal investigation for tax evasion.
Property transaction costs in Thailand are structured, predictable, and fully calculable in advance. The core rule: budget 5 to 7% above the purchase price to cover all fees, taxes, and professional legal services. Always ask your lawyer to produce a full itemized cost estimate before any contract is signed.
