Buying in Bangkok vs the UK: costs and taxes

In Bangkok you can own the flat but never the land, and you'll most likely pay cash. Back home you can own the lot, but living abroad makes the stamp duty bill bigger.

The short version

A Brit can own a Bangkok condo outright, within the building's 49% foreign quota and with the money sent in from abroad. Thai land is off limits. In the UK, anyone can buy anything.
Thailand's buying costs are modest: a 2% transfer fee on the appraised value, plus seller's taxes that the contract shares out [8].
England adds 2% for non-resident buyers and 5% on top if you'll own another home anywhere in the world, a Bangkok condo included [1][2].
Annual Thai land and building tax on a home is a fraction of a percent [9]. UK council tax is a different beast.
The UK taxes non-residents on UK property gains, with a 60-day return, and the Non-Resident Landlord Scheme covers letting your UK home [5][7].

What a Brit can buy in Bangkok, compared

Thai law keeps land ownership for Thai nationals. Foreigners can own a condominium unit, as long as foreign owners together hold no more than 49% of the building's total unit floor area, and as long as you can prove the purchase money came into Thailand in foreign currency, usually with a Foreign Exchange Transaction (FET) form from the receiving Thai bank. A house with a garden normally means a registered lease of up to 30 years, perhaps with ownership of the building itself. "Thai company" set-ups with nominee shareholders break the law. Proposals for a 75% condo quota and 99-year leases have been floated since 2024 but aren't law. Our Thailand property guide covers each route.

Back home, nobody asks where you're from. In England and Wales a house is usually freehold and a flat leasehold; Scotland has its own system. The nearest UK equivalent to a Bangkok condo is a leasehold flat with a service charge, except that in Bangkok you own the unit for good.

Upfront costs side by side

Take a one- or two-bedroom condo in Sukhumvit or Sathorn at THB 5 million (about £110,800), a like-for-like THB 13.5 million (about £299,300), and a £300,000 house in England.

	Bangkok condo	England, £300,000 house
Main transfer cost	Land Office transfer fee, 2% of the appraised value [8]	Stamp Duty Land Tax (SDLT), banded [1]
On our examples	Up to THB 100,000 (about £2,200) at THB 5 million; up to THB 270,000 (about £6,000) at THB 13.5 million	£5,000 for a UK resident buying their only home [1]
Seller's taxes	Withholding tax, plus either specific business tax of 3.3% or stamp duty of 0.5% [8]	None on the buyer
Foreign or non-resident surcharge	None, but the money must arrive as foreign currency	2% on top: £11,000 in total [1]
Owning another home	No effect	Higher rates, 5% on top: £20,000, or £26,000 if you're also non-resident [2]
Who pays what	Set by the sale contract; read that clause	The buyer pays SDLT

The appraised value is set by the Land Office and is often below the price you pay, so the transfer fee can come in lower than the table suggests. Thailand's temporary fee cuts for cheaper homes have been aimed at Thai buyers, so budget for the full 2%.

The bigger number in that table is England's. HMRC's higher rates apply if you'll own residential property worth £40,000 or more anywhere in the world after the purchase [2]. Keep the Bangkok condo, buy a cottage in Norfolk, and you're on the additional-home rates. If you've also spent fewer than 183 days in the UK in the 12 months before buying, the 2% non-resident surcharge goes on top [1]. If the new UK house replaces your main home and you sell the old one within three years, you can claim back the higher-rate part [2].

Scotland and Wales do it differently. Scotland's Land and Buildings Transaction Tax for 2026/27 is 0% up to £145,000, then 2%, 5%, 10% and 12% in bands, plus an 8% Additional Dwelling Supplement on the whole price for extra homes [3]: £4,600 on £300,000, or £28,600 with the supplement. Wales's Land Transaction Tax starts at 0% up to £225,000, and its higher residential rates run from 5% to 17% [4]: £4,500 on £300,000, or £19,950 at the higher rates. Neither has a non-resident surcharge.

Financing: Thai bank or UK lender?

In Thailand, mortgages for foreign buyers are thin on the ground. Some Thai banks lend to foreigners with a work permit and Thai income, on tighter terms than for Thai nationals, but most Brits buying a Bangkok condo pay cash. There's a practical reason too: the FET paperwork proves the money came from abroad, and you'll want the same paper trail to send the sale proceeds home one day.

Back home, a UK mortgage while you live in Thailand is possible but harder. Many high-street lenders won't lend to borrowers abroad or count baht income; specialist lenders and private banks will, usually with a bigger deposit and higher fees. Repaying a sterling loan from baht income can make it a foreign currency loan under FCA rules, with extra warnings when exchange rates swing. Some Brits release equity from a UK home to buy in Bangkok; that brings its own lender questions. See UK mortgages for Brits living abroad. And never cash in a UK pension to buy a condo without regulated financial advice.

Owning it: property tax and running costs

In Thailand, the Land and Building Tax replaced the old house and land tax. Residential property is taxed at a tiny fraction of a percent of the official appraised value, so the bill on a typical condo is usually small [9]. Check the current rate with the district office. Owners living in their own home get an exemption up to a threshold, and the district office can tell you whether yours qualifies. Then add the building's monthly common fees, set per square metre, and a one-off sinking fund payment when you buy.

One to watch: in July 2026 the Bangkok city administration was preparing a proposal to move rented-out condos into the "commercial (other)" category, with much higher rates than the residential ones [9]. It's only proposed and would need approval before it applies.

Back home, council tax is due whether you live there or not, and many councils in England and Wales add a premium on furnished second homes and long-term empty homes. Let the house, and the Non-Resident Landlord Scheme applies: your letting agent, or a tenant paying more than £100 a week, must take basic rate tax off the rent unless HMRC has told them in writing to pay you gross [7]. Apply on form NRL1, and you still file a UK return each year. See renting out your UK home.

Tax when you sell

The Thai side

There's no separate capital gains tax for individuals in Thailand. Instead, the Land Office collects the seller's taxes at transfer [8]:

Withholding tax for individuals, worked out on progressive income tax rates from the appraised value, with an allowance for the years you've owned it.
Specific business tax of 3.3% (including local tax) on the appraised value or the higher price, if you sell within five years of buying, in which case stamp duty doesn't apply.
Stamp duty of 0.5% otherwise.

On a THB 5 million condo sold within five years, the specific business tax alone is THB 165,000 (about £3,660). Remember the FET form: it's what lets your bank send the money back out as foreign currency.

The UK side

Selling UK property as a non-resident. Report every sale on a Capital Gains Tax on UK property return within 60 days of completion, even if no tax is due, and pay within the same 60 days [5]. For 2026/27, gains are taxed at 18% within the basic rate band and 24% above it, with a £3,000 tax-free allowance [6].
Private residence relief still covers the years you lived in the UK home plus the final nine months, but a year abroad only counts if you spent at least 90 nights there. See selling UK property as a non-resident.
Selling the Bangkok condo. While you're non-UK resident, a gain on foreign property is normally outside UK tax. Sell after you've moved back and HMRC taxes the worldwide gain at 18% or 24% [6], measured in pounds. A short spell abroad (five years or less) can bring gains on assets you owned before leaving back into charge in your year of return. After at least 10 tax years away, the 4-year foreign income and gains regime may give relief on foreign gains in your first four years back, at the cost of your tax-free allowances.
The treaty. The UK and Thailand have a double taxation convention, in force since 20 November 1981 [10]. Thai tax paid on the sale may be creditable against UK tax on the same gain; specific business tax and stamp duty are transaction taxes, so check how yours is treated.

Which makes sense for whom

Retirees settling in Thailand. A condo in your own name, bought in cash, is the honest and simple route; low annual tax helps. Rent first to be sure of the area.
Working in Bangkok for a few years. Renting keeps you flexible, and owning the condo can put you on England's higher rates when you buy back home.
Wanting a house and garden. That means a lease or a structure built around one. Price it as 30 years of use, not freehold.
Keeping the UK house. Sort NRL1, keep the 60-day clock in mind for a sale and check what your council charges on an empty home.
