Investors often ask: “What’s Thailand’s capital gains tax when selling property?” The answer is unusual: there’s no standalone “capital gains tax” in the familiar sense — a sale is taxed via a combination of withholding tax, specific business tax or stamp duty, and transfer fees. Let’s break down what makes up the burden, what drives it, and how to build it into your exit calculation. This is informational — a tax specialist computes the specific figures.

1. Is there “capital gains” in Thailand
Thailand has no standalone “capital gains tax” on property as in many countries. Instead of a single rate on sale profit, a combination of payments applies at transfer registration:
- withholding tax;
- specific business tax (SBT) or stamp duty;
- a transfer fee for registration.
The total burden depends on the holding period, seller status (individual/company) and appraised value. So “how much tax” is always a per-deal calculation.

2. Withholding tax
Withholding tax is the key payment on sale:
- for individuals it’s computed by a set method from the appraised/sale value factoring the holding period;
- for companies it’s counted differently (usually a percentage of value);
- it’s withheld at the moment of transfer registration at the Land Department.
This payment most often plays the role of a “profit tax” on sale, though formally it’s a withholding tax.
3. Specific business tax and stamp duty
Here the holding period is decisive:
- Specific business tax (SBT) applies if the property is sold before a set holding period (the sale is deemed “commercial”).
- Stamp duty applies instead of SBT if the property was owned longer than that period.
So SBT and stamp duty are mutually exclusive: you pay one or the other depending on holding period. Longer holding usually shifts the deal into the stamp-duty regime with a lighter burden.
4. Transfer fees
The transfer fee is the charge for registering the transfer at the Land Department (usually a percentage of appraised value). It’s levied regardless of holding period and is part of “deal costs”.
For leasehold the registration logic differs: the lease is registered (roughly ~1.1% for 30 years at purchase). The final set of payments depends on the ownership form.
5. What drives the total
| Factor | Effect |
|---|---|
| Holding period | Determines SBT vs stamp duty; affects withholding for individuals |
| Seller status | Individual and company are counted differently |
| Appraised value | Base for many payments |
| Ownership form | Freehold and leasehold — different registration logic |
| Agreements | How fees are split between parties |
Bottom line: the same sale at a different holding period and status yields a different burden. Calculate in advance and per specific deal.
6. Who pays what
Splitting taxes and fees between seller and buyer is a matter of contract agreement:
- in practice, parts of the fees are often shared between the parties;
- it’s important to set the split out in advance, before the deal;
- for a selling investor this directly affects “net” profit.
Don’t leave “who pays” to verbal understanding — fix it in the contract.
7. Building it into the exit calc
When planning a resale, count “net” profit after all payments:
- Price appreciation (sale minus purchase).
- Plus accrued rental income (owner ~8–10% net via the pool).
- Minus withholding, SBT/stamp duty, transfer fees.
- Minus selling costs (agent commission, etc.).
Only then do you see the real exit ROI, not “gross” appreciation. Project-model guides: 5-year ROI ~65%, 10-year ~78% (before the deal’s individual taxes).
8. Pitfalls
- Looking for a single “capital gains” rate. In Thailand it’s a combination of payments, not one tax.
- Ignoring the holding period. It drives SBT/stamp duty and the withholding calc.
- Counting “gross” appreciation. Real profit is after all taxes, fees and commissions.
- Not fixing the fee split. “Who pays” belongs in the contract, not in words.
- Forgetting home reporting. Tax obligations in your own country are on the investor; check your own regime.
9. Case: a sale calculation
Consider a typical scenario. An investor planned to sell a unit and wanted to know “net” profit. They didn’t chase an abstract “capital gains” rate but calculated the deal: price appreciation over the holding period, plus accrued rental income of ~8–10% a year, minus withholding, stamp duty (held long enough, so not SBT) and the transfer fee. The fee split was written into the contract in advance. The exit ROI came out predictable, with no “surprises” at registration.
Takeaway: “capital gains tax” in Thailand is a set of payments sensitive to holding period and seller status. Calculate them in advance and per specific deal — then the exit is transparent.
