What taxes and extra costs come with buying property in Thailand
When people first start looking at property in Thailand, they focus on the headline price. Then they realise the asking price isn’t the full budget. In real transactions, there are almost always extra costs: registration fees, possible transfer-related taxes, legal checks, bank charges, and for condos or new developments, project-level payments as well.
One key point upfront: some costs are “seller-side” on paper and some are “buyer-side”, but in practice a lot depends on what the parties agree in the contract. So it’s not just about knowing what fees exist — it’s about knowing who will actually pay them in your deal.
1) Ownership transfer registration fee
This is the main government fee when ownership is transferred. It’s commonly calculated as 2% of the official appraised value used by the Land Office. Many deals split it, but it’s not guaranteed — some sellers shift more (or all) of it to the buyer.
This is also one of the most commonly forgotten budget items when buyers look only at the advertised price.
2) Stamp duty or Specific Business Tax
People often assume both apply, but in many cases it’s one or the other. Typically it’s either 0.5% stamp duty or 3.3% Specific Business Tax, depending on the seller’s situation and holding period. If Specific Business Tax applies, stamp duty is usually not charged.
These are often treated as seller-side costs, but buyers should still pay attention because the economic burden can be baked into pricing or shifted through contract wording.
3) Withholding tax
Withholding tax is commonly collected at the Land Office during registration. The calculation differs depending on whether the seller is a company or an individual, and it can influence final negotiations even if it’s technically “seller-side”.
4) If the structure is a long-term lease instead of ownership
This matters a lot for houses and villas, where long-term lease structures are common. In that setup, registration costs are typically calculated as 1% of the total lease value over the full term, plus 0.1% stamp duty — roughly 1.1% in total.
Many buyers compare “ownership” and “lease” only by headline price, but the registration mechanics and side costs differ.
5) Legal review and transaction support
You can buy without a lawyer, but it’s usually a risky place to save money. Title checks, seller authority, debts, restrictions, contract terms, and the registration path are exactly the things that prevent you from buying a legal headache.
Fees vary by deal complexity, but the logic is simple: budget for legal review upfront.
6) Building-related costs: sinking fund and common area fees
For condos and many new projects, buyers usually face:
a sinking fund (one-time payment collected at handover to cover future major repairs), and
common area fees (regular payments for maintenance, security, facilities, and shared spaces).
These numbers depend on the specific project, so they should be confirmed in documents or with building management — not guessed.
7) Meters, deposits, and handover technical charges
Some projects charge for meter setup, utility deposits, or prepaid maintenance. These aren’t always huge, but they often show up late, when buyers think the main payments are done.
8) Bank fees and exchange-rate costs
For foreign buyers, bank transfer fees and exchange-rate spreads can be real money, especially on large transactions. It’s not a tax, but it is part of the real budget — so avoid budgeting too tightly.
Final thought
Buying property in Thailand isn’t just about the unit price. A realistic budget includes registration fees, possible transfer-related taxes, legal costs, bank charges, and for condos/new builds, project-level payments like sinking fund and common area fees. Some costs are “seller-side” on paper, but the final outcome depends on the contract — so the safest approach is to calculate the full budget before booking, not after.
