Thailand Property Sale Taxes in 2026: Exact Rates, Calculations, and Scenarios
A foreign investor sold a condo in Phuket for 12 million baht and paid 820,000 baht in taxes - when the correct figure, with proper planning, should have been closer to 490,000 baht. The difference was not bad luck. It was a lack of understanding of how Thailand's property sale tax system actually works.
Every time a property changes hands in Thailand, up to four mandatory charges are settled at the Land Office on the day of transfer. The total amount depends on how long the seller has owned the property, whether the seller is an individual or a company, and how the asset is legally structured. This article breaks down each charge with real numbers.
Quick Answer
- Transfer Fee - 2% of the appraised value, typically split 50/50 between buyer and seller
- Specific Business Tax (SBT) - 3.3% of the appraised value, charged when the property is sold within the first 5 years of ownership
- Stamp Duty - 0.5%, but only applies if SBT is not charged
- Withholding Tax - progressive scale from 5% to 35% for individuals; a flat 1% for corporate sellers
- Minimum combined tax burden when selling after 5 years of ownership is roughly 3.5 to 4% of the appraised value
- All taxes are collected directly at the Land Office at the moment of title transfer
The single most important planning decision for any seller is whether to wait until the 5-year mark. That one threshold affects two separate charges simultaneously and can save hundreds of thousands of baht on a mid-range property.
Scenarios and Options
Scenario 1: Individual Seller, Less Than 5 Years of Ownership
Consider a buyer who purchased a condo in Pattaya for 5 million baht and sells it three years later for 6.5 million baht. The Land Department's appraised value for that unit is 5.8 million baht.
All Land Office taxes are calculated against the appraised value set by the Land Department, not the actual sale price. The appraised value is often lower than the market price, which partially limits the tax base.
- Transfer Fee: 5,800,000 x 2% = 116,000 baht (seller's share: 58,000 baht)
- SBT: 5,800,000 x 3.3% = 191,400 baht (paid by the seller, ownership under 5 years)
- Withholding Tax: calculated using the progressive Personal Income Tax (PIT) scale, with the appraised value divided by years of ownership before applying the rate table, then multiplied back. For a 3-year holding period, the estimated liability is approximately 175,000 to 200,000 baht
- Stamp Duty: not charged because SBT applies
Total seller-side cost: approximately 425,000 to 450,000 baht, representing roughly 6.5 to 7% of the appraised value.
Scenario 2: Individual Seller, More Than 5 Years of Ownership
The same property, sold after 6 years. The key change: SBT no longer applies. Stamp Duty replaces it at a much lower rate.
- Transfer Fee: 116,000 baht (seller's share: 58,000 baht)
- Stamp Duty: 5,800,000 x 0.5% = 29,000 baht
- Withholding Tax: with 6 years of ownership, the effective rate drops materially. Estimated liability: 100,000 to 130,000 baht
- SBT: 0 baht
Total seller-side cost: approximately 187,000 to 217,000 baht, representing roughly 3.2 to 3.7% of the appraised value. The saving compared to Scenario 1 is close to 50%.
Scenario 3: Corporate Seller via Thai Company (Thai Co., Ltd.)
When a property is held through a Thai company, the Withholding Tax at the Land Office is a flat 1% of whichever is higher - the appraised value or the contract price. However, the company then owes Corporate Income Tax (CIT) at 20% on net profit when filing its annual return.
This structure tends to be advantageous when the resale margin is modest or when the company has significant deductible operating costs that reduce the taxable profit base.
| Parameter | Individual (under 5 years) | Individual (over 5 years) | Thai Company (Corporate) |
|---|---|---|---|
| Transfer Fee | 2% (split) | 2% (split) | 2% (split) |
| SBT | 3.3% | 0% | 3.3% if under 5 years, otherwise 0% |
| Stamp Duty | 0% (replaced by SBT) | 0.5% | 0.5% if SBT does not apply |
| Withholding Tax | 5-35% progressive | 5-35% progressive | Flat 1% of value |
| Corporate Income Tax | Not applicable | Not applicable | 20% of net profit |
| Total Estimated Burden | 6-8% | 3-5% | 3-6% depending on profit margin |
| Best Suited For | Unavoidable if selling early | Optimal for long-term holders | Low-margin resales with deductible costs |
How Withholding Tax Is Calculated for Individuals
This is the most misunderstood element of the entire system. The Land Office applies the following method:
- Start with the appraised value of the property (not the sale price)
- Divide by the number of years of ownership, capped at 10 years
- Apply standard deductions under the Revenue Code to the resulting figure
- Apply the Thailand Personal Income Tax (PIT) progressive rate table to the remainder:
- Up to 150,000 baht: 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%
- Multiply the resulting tax figure back by the number of years of ownership
The longer you hold, the lower the effective Withholding Tax rate. This is why the 5-year threshold matters twice - it removes SBT and simultaneously reduces Withholding Tax by spreading the appraised value over more years.
Double Taxation: Protecting Income Across Borders
Thailand has signed Double Tax Agreements (DTAs) with 61 countries. For sellers who are tax residents of countries with an active DTA, income from Thai property sales is generally taxable in Thailand - and the tax paid in Thailand can typically be credited against liability in the home country.
Practical guidance: keep all Land Office receipts, including the Withholding Tax payment confirmation. These documents are required to substantiate any foreign tax credit claim in your country of residence. Specific credit rules vary by jurisdiction, so consult a tax adviser in your home country before finalizing the sale.
Main Risks and Mistakes
1. Understating the contract price. Some sellers agree with buyers to record a lower figure in the sale agreement to reduce taxes. The Land Office compares the contract price with the appraised value and uses whichever is higher. If the gap is too large, the transaction may be delayed or trigger an audit.
2. Miscounting the ownership period. The 5-year clock starts from the date of Land Office registration, not from the date of signing the purchase agreement or paying a deposit. Being off by one month means paying the full 3.3% SBT.
3. Ignoring home-country tax obligations. Withholding Tax paid in Thailand does not automatically satisfy your tax obligations in your country of residence. Most countries require you to declare foreign-source income even if tax was already withheld abroad.
4. Using a Thai company without genuine business activity. If a Thai Co., Ltd. was created solely to hold a single property and has no real operations, the Revenue Department may challenge the structure. Since 2024, scrutiny of inactive holding companies has intensified significantly.
5. Confusing appraised value with market value. Every Land Office tax is calculated on the appraised value, which is reassessed every four years. In 2026, the current appraisal cycle values are in effect, and they may differ substantially from the price you are actually selling at - in either direction.
6. Assuming leasehold sales follow the same rules. When selling a leasehold interest rather than freehold title, what is being transferred is a contractual right rather than ownership. The tax treatment differs from a standard freehold sale and should be verified with a property lawyer before proceeding.
FAQ
Who pays which taxes - the seller or the buyer? Transfer Fee is conventionally split equally. SBT, Stamp Duty, and Withholding Tax are the seller's responsibility. However, all of this is negotiable and should be clearly stated in the sale and purchase agreement.
Can SBT be avoided by gifting the property to a family member? Transfers by inheritance or as gifts to direct heirs (children, parents, spouses) are exempt from SBT. Gifts to non-relatives may still trigger SBT, and a separate gift tax may also apply.
Do I owe taxes if I sell at a loss? Yes. Withholding Tax is calculated on the appraised value, not on actual profit. Even if your sale price is below your original purchase price, Withholding Tax will still be withheld at the Land Office. For corporate sellers, a genuine loss reduces CIT, but the 1% Withholding Tax is still collected at transfer.
How can I get an accurate tax estimate before the sale? Bring a copy of your chanote (title deed) to the relevant Land Office. An officer will calculate the exact tax amounts for your specific transaction at no charge. This is a standard procedure and is available to foreign sellers.
Does the type of ownership affect taxes (freehold vs. leasehold)? For freehold properties, the standard Land Office tax schedule applies. For leasehold transfers, the tax base and applicable charges differ. If you are selling a lease rather than a title, confirm the applicable rules with a qualified Thai property lawyer before proceeding.
Is a Thai Tax ID number required to sell property? For a non-resident individual making a one-off sale, a Tax ID is not strictly required - the Land Office will withhold and remit the Withholding Tax automatically. However, having a Tax ID makes it easier to obtain official payment certificates, which may be needed when claiming a foreign tax credit in your home country.
What changed in Thailand property taxes in 2026? Thailand continues to apply the rates introduced in 2019. A proposed increase in Transfer Fee from 2% to 3% has not been enacted. The most significant recent development is heightened scrutiny of inactive holding companies and stricter source-of-funds checks at the Land Office.
Selling property in Thailand rewards those who plan ahead. The core principle is straightforward: if you can wait until the 5-year mark, do so. The difference between selling in year four versus year six includes 3.3% SBT plus a lower effective Withholding Tax rate. On a property appraised at 10 million baht, that saving can reach 400,000 to 500,000 baht - a meaningful return on patience.
