Thailand property taxes: build a reliable closing budget
There is no single percentage that accurately predicts every Thai property's closing cost. The seller's status, transaction type, tax base, exemptions and date can change the result. Build an itemised estimate and confirm the official calculation before completion.
Collect the inputs before using a calculator
Record whether the seller is an individual or company, the asset being transferred, acquisition date and manner of acquisition, agreed price and relevant official assessed value. Ask which exemptions or temporary measures are claimed and what evidence supports them. A rate shown in an old article or another buyer's receipt is not enough. Keep the estimate dated and tie it to the exact proposed registration, especially if a closing moves into a different policy period.
Keep fees, withholding and transaction taxes separate
Request individual lines for the registration or transfer fee, applicable withholding income tax, specific business tax and stamp duty. Each line should state its tax base, rate or calculation method, legal payer, contractual allocation and supporting authority. Do not assume that every line is a percentage of the advertised price. Withholding treatment differs between individual and corporate sellers, so an estimate should show which category was used rather than hiding it behind a total.
- Transfer or registration fee: confirm the applicable instrument and any eligibility-limited relief.
- Withholding: request the seller-specific computation and the documents used.
- Other closing costs: identify mortgage releases, translations, representation and agreed service charges separately.
Check specific business tax and stamp duty as a decision
The Revenue Department describes taxable property-sale categories and exemptions for specific business tax. Do not reduce the analysis to a universal ‘held for five years’ shortcut. Its property stamp-duty guidance also explains the exemption where specific business tax is paid; adding both indiscriminately overstates the bill. Ask the preparer to state which treatment applies, why, and which facts could change it. The Revenue Department sources below address these two questions directly.
Write who pays without disguising who owes the tax
A sale agreement can allocate economic costs between buyer and seller, but contractual wording does not by itself rewrite statutory tax obligations. Ask counsel to replace vague wording such as ‘all taxes shared’ with clearly identified items and an adjustment process if the official amount differs. Before transfer, agree who provides funds for each item, how any deposit is credited and how receipts will be collected. Do not understate the actual price to make an estimate look cheaper.
Budget annual ownership and income obligations separately
The Land and Buildings Tax is a separate local-authority matter, with classification and applicable relief requiring review for the actual use and owner. Request the latest assessment and payment evidence, and confirm how the authority should be informed after transfer. If you plan to rent, ask a tax adviser about income reporting and your wider tax position, including relevant cross-border obligations. Condominium charges, estate fees, insurance and repairs belong in your holding budget but are not interchangeable with tax.
Verify before you pay
Tell us about the property and your proposed purchase. The client intake helps establish the checks and service scope needed. Firm availability and timing must be confirmed for your matter.

Can the buyer and seller simply split all charges 50/50?
They may negotiate allocation, but the contract should identify each item and respect statutory obligations. Ask for an itemised calculation and explicit wording rather than assuming a general split covers every tax and fee.
Does a temporary transfer-fee reduction apply to every foreign buyer?
Do not assume eligibility. Temporary measures may restrict the buyer category, property type, value or dates. Confirm the operative measure and your eligibility with the receiving office before using it in the budget.
