Thailand Property Taxes for UK Buyers: Report Thai Rent in the UK
See what UK buyers pay on Thai property, how rent and sales are taxed, when annual bills arrive, and how to report Thai income and claim treaty relief.
If you buy property in Thailand, expect an annual land and building tax, transfer-stage charges, Thai tax on Thai-sourced rent, and withholding when you sell. UK residents can generally claim credit for Thai tax paid under the 1981 UK–Thailand Double Taxation Convention. Keep every Thai receipt and be ready to report it on your UK self-assessment return.
TL;DR:
- The owner registered on January 1 owes the full annual land and building tax, even after a midyear sale; bills usually arrive in February.
- Land Office transfer charges and sale withholding use the appraised value, not the agreed price; sellers can offset withholding through an annual return.
- Rental income allows a 30% standard deduction or documented actual expenses, so landlords should compare the options and retain proof for every expense.
- At 180 days in a Thai tax year, individuals become residents, and certain foreign income brought into Thailand may also be taxable.
- Personal and company ownership follow different filing routes, while registered leases or superficies add registration costs; settle the structure before signing or renting.
How does Thailand's Land and Building Tax affect UK owners?
The Land and Building Tax Act B.E. 2562 replaced the old local taxes with a value-based annual tax. Whoever owns the property on 1 January is liable for the whole year, so a mid-year sale does not hand you a refund. Liability follows the registered owner, which includes foreigners who lawfully hold a condominium unit or a registered superficies or lease.
Bills are usually issued in February, and not receiving one does not excuse payment. Late payment attracts surcharges that build up month by month, up to a cap. Foreign owners may pay using passport details or through an agent.
Practical steps for a UK-based owner:
- Make sure the title registry and local office hold a current contact address, because a missed bill is the commonest cause of surcharges.
- Appoint an agent or grant a power of attorney so someone in Thailand can collect and pay the bill.
- Ask whether any principal-residence exemption could apply to your circumstances before assuming the full rate.
- Diarise February every year, even if you have never received a notice.
Pro Tip: Set up the payment arrangement at the point of transfer, not after your first missed bill.
What taxes and fees do you pay when you buy?
Most purchase charges are settled at the Land Office on the day of transfer. The transfer fee is calculated using the Land Office appraised value, rather than whatever price you agreed with the seller. That distinction matters later, because the same appraised value drives the seller's withholding.
Stamp duty and Specific Business Tax (SBT) are alternatives rather than additions. The Revenue Department explains SBT as applying where immovable property is sold in a commercial or profitable manner, in which case SBT is charged instead of stamp duty. SBT also carries registration requirements of its own, and the procedural chapter on SBT links the tax to the land registration process.
What to expect in practice:
- Transfer fee: calculated on the appraised value and paid at the Land Office.
- Stamp duty or SBT: one or the other, depending on how the seller held and sold the property.
- Lease registration fees: apply if you take a registered lease rather than ownership.
- Who pays: by convention buyer and seller often split or negotiate these charges, so settle the allocation in the contract before transfer day.
How is rental income taxed for non-residents?
Rent from Thai property is Thai-sourced income and is taxable in Thailand. Under Revenue Department guidance, you may deduct either a flat 30% of gross rent or your actual expenses, provided you can prove them with documents. Non-residents must file a return if their Thai-sourced income meets the reporting thresholds.
The Revenue Department allows a 30% standard deduction on rental income, or actual expenses with supporting proof. Choosing actual expenses only pays off if your records are complete.
For most individuals the filing vehicle is form ภ.ง.ด.90, and the Revenue Department's guide to the form explains who must file and how rental income is reported. Points to bear in mind:
- Keep contracts, invoices and proof of payment for every expense you may claim.
- Retain the Thai tax receipts you will need for your UK return and any treaty claim.
- Reporting differs if you hold the property through a company rather than personally, so settle the structure before the first tenant.
How is tax collected when you sell?
At transfer, the Land Office withholds tax using the Department's appraised value, not the actual sale price. The Revenue Department's personal income tax pages confirm that sellers may include the transfer in their annual personal income tax return, so the withholding is offset against the year's overall liability. The alternative is a separate computation supported by documented expenses.
This is where an appraised value that sits well above your sale price bites. Withholding is still taken on the higher figure, and you then wait to recover any excess through the annual return.
What to do:
- Obtain the appraised value before you agree a price, so you know the withholding in advance.
- Keep the purchase contract, proof of improvements and sale documents together.
- Ask for the withholding certificate at transfer and file it with your records.
- Decide early whether the annual return or the separate computation suits your numbers.
How do the 180-day rule and the UK treaty work together?
Thailand treats an individual present for 180 days or more in a tax year as a resident. Residents pay tax on Thai-sourced income and on certain foreign income brought into Thailand, while non-residents are taxed only on Thai-sourced income.
Under the 1981 convention, income from immovable property may be taxed where the property sits, which is Thailand, and the UK allows a credit for the Thai tax paid. HMRC's helpsheet on double taxation relief sets out how claims work in practice.
- Keep every Thai tax receipt and withholding certificate.
- Obtain any certificate of residence or tax paid that your claim requires.
- Check the treaty text for whether relief is full or partial in your case.
- Report the Thai income and claim the credit on your UK self-assessment return.
What is your practical filing and payment checklist?
Treat this as a yearly routine rather than a one-off task. The land and building bill arrives in February, the individual return covers rent and any sale, and SBT filings arise only where a transaction falls within that regime.
- Confirm the address on the title registry and keep your agent's authority current.
- Pay the land and building bill when it arrives; surcharges add up for each month of delay.
- File the individual return, covering rent and any sale you chose to include.
- File SBT registrations or returns where they apply to your transaction.
- Store Thai receipts, appraisals and withholding certificates for your UK return.
Pro Tip: Scan every document on the day you receive it and name the files by tax year, so a treaty claim never depends on a search through old emails.
What might the numbers look like? A worked example
The following is illustrative only. Say a condominium has a Land Office appraised value of 5,000,000 baht, and you rent it out for 300,000 baht a year.
- Transfer fee: 2% of 5,000,000 baht is 100,000 baht.
- SBT or stamp duty: depends on how the seller held and sold the property, so ask your adviser which applies.
- Rental deduction: the 30% standard deduction on 300,000 baht is 90,000 baht, leaving 210,000 baht as the amount subject to Thai personal income tax at the bracket rates.
These inputs are assumptions, not market data. The Revenue Department's rental guidance governs the real computation, and the rate bands vary by income.
How do ownership structures change your tax position?
Foreigners generally hold Thai property through one of a few routes, and each routes the tax differently. Freehold condominium ownership puts the unit in your own name, so land and building tax, rental income and sale proceeds all fall on you personally. A registered lease or superficies gives you rights rather than outright ownership, and the lease registration fee is an extra charge at the outset.
Holding through a company changes the reporting. Rent and sale income are then reported by the company rather than by you, and the SBT question depends on how the vendor, not the buyer, is organised. Where a seller is a business selling in a commercial or profitable manner, expect SBT rather than stamp duty to appear in the transfer costs.
The structure you choose also sets the paperwork you will carry for years. A personal holder files the individual return and keeps receipts for their UK claim. A company holder follows company filing rules and has a different route for any treaty relief. Because the right answer depends on your residency, your plans for letting and your exit, settle the structure before you sign anything, not after. We review ownership structure as part of a file prepared before buying, since an awkward holding route is far cheaper to avoid than to unwind.
What happens to Thai property on inheritance?
We have no published source in this brief on Thai inheritance or estate rules, so we will not quote rates or thresholds. What can be said is practical. Property in Thailand stays subject to Thai land registration when an owner dies, so the title has to be transferred to the heirs through the Land Office, and the paperwork for that process involves the same appraisal and documentation issues covered above.
For a UK owner, there are two sets of rules to think about: Thai rules on the property sitting in Thailand, and UK rules on your estate. The treaty text published on GOV.UK is the place to check how the two countries divide taxing rights, and a qualified adviser should confirm the position for your family.
Three habits reduce friction for heirs:
- Keep the title documents, tax receipts and appraisals in one place that a family member can find.
- Make sure your Thai will, if you have one, is drafted by someone who knows Thai property procedure.
- Record who holds any power of attorney, and when it expires.
Our view: three tax errors we see UK buyers make
Owners leave an out-of-date address at the registry, miss the annual bill and pick up surcharges. Landlords lose the option of claiming actual expenses because they never kept receipts. Sellers ignore the gap between appraised value and market price, and find the withholding larger than they expected. All three are avoidable with early due diligence.

FAQ
What tax do you pay in Thailand on property?
Owners pay an annual land and building tax, buyers pay transfer-stage charges, landlords pay Thai personal income tax on rent, and sellers face withholding at transfer. Which charges apply depends on your use of the property.
Can a UK resident buy a house in Thailand?
Foreigners can lawfully own a condominium unit and can hold registered leases or superficies, as covered above. Ownership of other property types is more restricted, so check the structure before you commit.
Do UK residents get relief for Thai tax?
Generally yes. The 1981 UK–Thailand convention allows a credit for Thai tax paid on property income, claimed on your UK self-assessment return with supporting receipts.
How is tax calculated when you sell in Thailand?
The Land Office withholds using the appraised value rather than the sale price. You may then include the transfer in your annual return so the withholding offsets your yearly liability.
