Phuket Property Guide for British Buyers: Tax & Ownership

As a British buyer, you can absolutely own property in Phuket — a condominium in freehold, or a villa on a long lease — and nothing in Thai law singles you out for being from the UK. The real catch is not in Thailand at all: it is at home. If you remain UK-resident, HM Revenue & Customs taxes you on your worldwide income and gains, so the rent you earn in Phuket and the profit you make when you sell are both reportable in Britain — and since 6 April 2025 the old “keep the money offshore” shelter (the remittance basis) has gone.

That single fact is what makes buying in Phuket different for you than for the French, Chinese or Emirati buyer standing next to you at the same show unit. This article is a hub: it goes deep on your UK-side obligations — the part no Thai developer will ever explain — and links out to our detailed spoke guides for the shared Thailand mechanics (freehold vs leasehold, off-plan safety, yields, visas, the FET form). None of this is tax or legal advice; every figure below is tied to the 2025/26 UK tax year and can change at any Budget, so confirm your own position with HMRC or a qualified cross-border adviser before you act.

Key takeaways

• You can buy. Foreigners may own a Phuket condo in freehold within a building’s 49% foreign-ownership quota (Condominium Act B.E. 2522). Land is generally off-limits to foreigners, so villas are usually held on long leasehold, commonly 30 years. See our freehold vs leasehold guide.
• Buying does not get you a visa. Property ownership alone grants no right to stay. Your route is a separate DTV, LTR, Elite/Privilege or retirement visa — compare them in our long-stay visa guide.
• If you are UK-resident, HMRC taxes the rent and the gain. Foreign rental income and capital gains on overseas residential property are both reportable through Self Assessment.
• UK Capital Gains Tax on residential property is 18% (basic band) / 24% (higher & additional band) for 2025/26, with a £3,000 annual exempt amount (GOV.UK).
• The remittance basis is abolished from 6 April 2025 — leaving money in a Thai bank no longer keeps it out of UK tax.
• Double tax relief may be available under the 1981 UK–Thailand treaty, but it is capped and not automatic.
• Palmora regularly guides British buyers and can connect you to cross-border tax and legal specialists. Start at /en/contact.

What you can (and cannot) own in Phuket

The Thailand ownership rules apply to you exactly as they do to any foreigner — your nationality neither helps nor hurts here.

A condominium can be held in freehold (permanent, transferable title) provided the total foreign-owned floor area in the building stays within the 49% quota set by the Condominium Act. This quota is measured per building, by floor area, not by unit count, and it must be checked at the specific project and Land Office before you commit — once the foreign side is full, the usual alternative is a leasehold of around 30 years with renewal options.

Land is a different matter: foreigners generally cannot own land in freehold, so a villa or house is typically structured as a long-term lease (commonly 30 years) rather than direct ownership. There are narrow exceptions (for example BOI or treaty-based routes), which is exactly why you want a Thai property lawyer rather than a rule of thumb. We unpack the trade-offs — and the wider legal aspects of buying in Thailand — in our freehold vs leasehold guide.

One mechanical point that matters to you as a British buyer paying from a UK account: to register foreign freehold on a condo, Thai law generally requires the purchase funds to be remitted into Thailand in foreign currency and converted to baht, evidenced by a Foreign Exchange Transaction (FET) form from the receiving Thai bank. Plan your transfer so the paperwork lines up — our paying for property guide walks through bank transfers, the FET and the alternatives.

The part that is uniquely yours: UK tax on a Phuket property

Here is where being British changes the maths. The starting question is not about Thailand — it is: are you UK-resident?

Your residence is determined by HMRC’s Statutory Residence Test, not by where you feel at home. It matters enormously:

• If you are UK-resident, you are taxed on your worldwide income and gains. Your Phuket rent and your eventual sale profit are within scope of UK tax.
• If you are non-UK-resident, you are generally outside UK Capital Gains Tax on an overseas property such as one in Thailand.

Do not assume your status — a retiree splitting the year, a remote worker on a DTV, and a family that has genuinely emigrated can all reach different answers. Get your residence position confirmed before you model any returns.

Rental income: declared on the SA106 “Foreign” pages

If you are UK-resident and let your Phuket property, the rent is foreign income that must be declared to HMRC on the Foreign supplementary pages (form SA106) of your Self Assessment return. Income is grouped by country and each amount is converted to sterling at the exchange rate when it was received (GOV.UK / HMRC SA106 notes 2025). You cannot simply net it off against your salary and forget it.

Capital gains: Self Assessment, not the 60-day service

When you sell, the gain on an overseas residential property is reportable — but not through the 60-day UK-property reporting service that applies to UK homes. Instead it goes through your annual Self Assessment return, due by 31 January following the tax year of sale, with the gain computed in sterling using the exchange rate at each transaction date (HMRC). That currency point can cut both ways: a weaker pound at completion can inflate your sterling gain even if the baht price barely moved.

For 2025/26 the rates are:

• 18% on residential property gains falling within your basic-rate income band;
• 24% on gains above it (higher and additional band);
• after deducting the £3,000 annual exempt amount (GOV.UK).

Treat both the rates and the allowance as year-specific — the £3,000 exemption has been falling in recent years and can be changed at any Budget.

The 2025 change that closes the old loophole

For decades, some British owners of foreign property relied on the remittance basis: keep the rent and gains in an offshore account, and UK tax only bit when you brought the money home. That is over. From 6 April 2025 the UK abolished domicile and the remittance basis; the last year a remittance-basis claim could be made was 2024/25. From 2025/26 all UK residents are taxed on their worldwide income and gains on the arising basis (GOV.UK / HM Treasury technical note).

The replacement — the 4-year Foreign Income and Gains (FIG) regime — is narrow and is not a shelter for ordinary long-term UK residents. It is available only to people who become UK-resident after at least 10 consecutive tax years of non-residence, and only for their first four years of UK residence (GOV.UK). If that is genuinely you (say, you are returning to Britain after a long stint abroad), it may exempt eligible foreign income and gains — but if you are a settled UK resident buying a Phuket condo, the money staying in Thailand no longer keeps it out of UK tax.

Double tax relief: available, but capped

You will not necessarily be taxed twice. Thailand levies its own transaction taxes on sale (transfer fee 2%; then either stamp duty 0.5% OR, if you sell within five years, Specific Business Tax 3.3% — not both), and it taxes rental income locally. As a UK resident you can claim Foreign Tax Credit Relief on the SA106 for Thai tax paid on the same income or gain (HMRC). The credit is generally the lower of the UK tax due or the foreign tax paid, and it is governed by the 1981 UK–Thailand Double Taxation Convention (in force since 1981, modified by the Multilateral Instrument from 1 January 2023), which uses the credit method for relief (GOV.UK).

Relief is not automatic and interacts with Thailand’s own evolving rules — since 1 January 2024 a Thai tax resident (180+ days per year) is taxed on foreign income remitted to Thailand, and a widely-discussed two-year-window proposal for 2025 is not yet law. Frame it as relief may be available, subject to the treaty and professional advice.

Visas, pensions and retirement

Buying in Phuket gives you a home, not the right to live in it. Choose your visa separately.

The common routes for British buyers are the DTV (5-year, aimed at remote workers, around 500,000 THB in savings), the LTR 10-year BOI visa, the Thailand Privilege (formerly Elite) membership visa, and the O-A retirement visa (50+, 800,000 THB deposit). The full comparison is in our long-stay visa guide.

If you are a retiree, the LTR “Wealthy Pensioner” category is worth a look: it requires applicants aged 50+ with passive/pension income of at least USD 80,000/year, or USD 40,000/year plus at least USD 250,000 invested in specified Thai assets (HLB Thailand, summarising BOI criteria). The BOI relaxed several LTR criteria in 2025, so verify current thresholds on the official BOI portal (ltr.boi.go.th) before relying on any number. Note too that the LTR’s headline “tax exemption on foreign-sourced income” is a Thai-side benefit — it does not, by itself, change your UK tax position.

Pensions deserve a specific warning. If you are tempted to move a UK pension abroad, be careful: a 25% Overseas Transfer Charge (in place since 2017) may apply to transfers of UK pension savings to a QROPS unless an exclusion applies (such as transferring to a QROPS in your country of residence). HMRC currently lists no QROPS based in Thailand, so that same-country exclusion is not available to Thailand-resident Britons (GOV.UK guidance / ROPS list). This is flagged high-level only and is not advice — mis-transfers carry severe penalties, so speak to a regulated pensions adviser before moving anything.

The Phuket investment case, in brief

The numbers that draw British buyers are real but should be read soberly, and never as “guaranteed.” Phuket’s median condo price sits around 140,000–144,000 THB/sqm (C9 Hotelworks, April 2025), and average gross rental yields are roughly 5.8% in 2025 (Colliers), with prime, well-managed units reaching 7–8.5% gross and net returns of around 5–10% depending on strategy. We keep the detail current in our Phuket rental yields 2026 guide, which also covers the practicalities of letting and running a holiday home you rent out.

If you plan to buy without flying out, buying remotely from abroad walks through doing it safely — and for new-build risk, off-plan buyer protection (EIA, escrow) is essential reading before you pay a deposit.

Frequently asked questions

Do I pay UK tax on rent from my Phuket condo? If you are UK-resident, yes. Foreign rental income is declared to HMRC on the SA106 Foreign pages of your Self Assessment return, converted to sterling at the exchange rate when received. You may be able to credit Thai tax paid on the same income under the UK–Thailand treaty. If you are genuinely non-UK-resident, different rules apply — confirm your status first.

Will I be taxed twice — in Thailand and in Britain? Not usually to the full extent. Thailand taxes the income/transaction locally, and as a UK resident you can claim Foreign Tax Credit Relief on the SA106 for Thai tax on the same income or gain. The credit is the lower of the UK or Thai tax, under the 1981 UK–Thailand treaty. Relief is not automatic, so take advice.

I heard the non-dom rules changed — does that affect me? Yes, if you are UK-resident. The remittance basis was abolished on 6 April 2025. You can no longer keep Thai rent or sale proceeds offshore to avoid UK tax; UK residents are now taxed on worldwide income and gains as they arise. The replacement 4-year FIG regime only helps people arriving in the UK after 10+ years of non-residence.

How much Capital Gains Tax will I pay when I sell? For 2025/26, UK CGT on residential property is 18% within the basic-rate band and 24% above it, after the £3,000 annual exempt amount (GOV.UK). You report it through Self Assessment by 31 January after the tax year of sale — not the 60-day UK-property service — with the gain computed in sterling. Thailand also charges a 2% transfer fee plus either 0.5% stamp duty or, if you sell within five years, a 3.3% Specific Business Tax (not both).

Does buying a condo in Phuket give me a visa or residency? No. Property ownership grants no right to stay. You need a separate visa — DTV, LTR, Thailand Privilege or a retirement visa. Compare them in our visa guide.

Can I really own the property outright as a foreigner? A condo can be owned in freehold within the building’s 49% foreign quota. Land generally cannot, so a villa is usually held on a long lease (around 30 years). The quota is checked per building at the Land Office, and structures should be reviewed by a Thai property lawyer — see our freehold vs leasehold guide.

Should I move my UK pension to Thailand? Tread very carefully. A 25% Overseas Transfer Charge may apply to QROPS transfers, and HMRC currently lists no QROPS in Thailand, so the same-country exclusion is unavailable. This is high-level information only — consult a regulated pensions adviser before doing anything.

Important disclaimer

This article is general information, not tax, legal, financial or immigration advice, and it does not create an adviser relationship. Tax rules change frequently and are personal to your circumstances; all UK figures are stated for the 2025/26 tax year and can change at any Budget. Whether you are UK-resident (and therefore taxed on worldwide income and gains) depends on the Statutory Residence Test applied to your own situation. Some Thailand-side points (leasehold for land, the FET requirement, visa thresholds) are sourced to reputable law and advisory firms rather than a single government page and should be verified with official sources — HMRC, the Thai Revenue Department, the BOI (ltr.boi.go.th) and a qualified Thai property lawyer. Always confirm current rules with HMRC, the BOI, or a qualified cross-border adviser — or ask Palmora to introduce you to one — before acting.
