A UK property purchase from overseas is rarely a single tax decision. It is a stack of decisions, most of which need to be made before exchange of contracts and almost all of which become more expensive to fix afterwards.
The tax stack on a typical expat purchase includes:
This article covers the buying-side tax decisions: SDLT, surcharges, structure choice and the calculations that drive the total cost. The corresponding ownership-side and disposal-side tax decisions (NRL, NRCGT, ATED, IHT) sit in the dedicated guide to UK property tax during ownership and disposal.
The applicable rules apply in England and Northern Ireland under SDLT. Scotland operates the Land and Buildings Transaction Tax (LBTT) with its own non-resident treatment, and Wales operates the Land Transaction Tax (LTT) with similar variations. The structure described here is the SDLT framework, but the underlying logic is broadly similar in all three regimes, with bands and surcharge rates differing.
The practical aim of this article is to give an expat buyer enough understanding to model the realistic SDLT cost before any property is reserved, then to make the structure choice in line with that cost rather than against it.
For completions in 2026, the standard residential SDLT bands apply for first-property purchases by UK residents:
{{INSET-CODE-5}}
SDLT is calculated band-by-band, not as a flat rate on the whole purchase price. A £600,000 property pays:
The same band-by-band logic applies regardless of whether the buyer is UK resident or non-resident, and regardless of whether the property is a first home, second home or buy-to-let. The buyer's residency and the property's status then layer surcharges on top of these bands.
The current band structure has been in force since 1 April 2025, when the SDLT thresholds reverted to the pre-2022 levels. No further changes have been announced for 2026, and the 2026/27 tax year continues with the bands above. Any future changes would normally be announced at the Budget, with at least a few months' notice for completions, although the Government retains the right to introduce earlier changes for transitional rule purposes.
{{INSET-CTA-1}}
Non-UK residents who purchase residential property in England or Northern Ireland pay an additional 2% SDLT surcharge on every band of the standard rates. The surcharge has been in force since 1 April 2021 and is unchanged in 2026.
The critical detail is the residency test. For SDLT purposes, you are a non-UK resident if you have spent fewer than 183 days in the UK in any continuous 365-day period that includes the day before completion and the 364 days before and after. The test is binary, decided at the date of completion, and uses physical presence rather than tax residency.
The 2% surcharge applies to:
The surcharge sits on top of standard SDLT, so the calculation is:
{{INSET-CODE-6}}
Buyers who become UK-resident within 12 months of completion (by spending 183+ days in the UK in the 12 months after) can apply for a refund of the 2% surcharge. The refund is not automatic and requires a formal claim within the relevant time window.
The residency test catches more buyers than expected. A UK national who has spent 170 days in the UK in the relevant window is non-resident for SDLT, even if they consider themselves UK resident in every other respect. A buyer who is mid-relocation back to the UK and has just crossed onto British soil three weeks before completion is also non-resident, until enough days accumulate. Borrowers planning a UK return that coincides with a property purchase often find it cheaper to time exchange and completion to fall after the 183-day threshold rather than before it, with the refund route as a fallback if timing is uncertain.
The surcharge applies to the whole purchase price, not the portion above any threshold. There is no first-£125,000 exemption from the 2% surcharge. The whole property attracts the 2% from the first pound.
{{INSET-CODE-1}}
Where the property being purchased is a second home, holiday home or buy-to-let, an additional 5% SDLT surcharge applies on every band of the standard rates. The surcharge was raised from 3% to 5% with effect from 31 October 2024 and is unchanged in 2026.
This surcharge applies whether the buyer is UK resident or non-resident, but stacks with the 2% non-resident surcharge for non-resident buyers of additional dwellings:
{{INSET-CODE-7}}
The 5% surcharge applies if, at the end of the day of completion, the buyer owns more than one residential property worldwide and the new property is not replacing the buyer's main residence. For non-resident expats who already own property in their country of residence, the new UK property is almost always treated as an additional dwelling, even where it is intended as a future primary residence on return to the UK.
This catches a meaningful share of expat buyers. A UK national living in Dubai who owns a villa in the UAE and is buying a flat in London for future return is, on the strict reading of the rule, buying an additional dwelling. The villa is a residential property the buyer owns worldwide, the flat is the new purchase, and the buyer is not selling the villa as part of the transaction. The 5% surcharge therefore applies, on top of the 2% non-resident surcharge, on top of the standard rates.
Replacement of main residence relief is one route around the 5% surcharge, but it requires the buyer to be selling their previous main residence as part of the purchase. For most expat cases, the property in the country of residence is not being sold at the time of the UK purchase, and so the relief does not apply.
Transitional rules protect contracts exchanged on or before 30 October 2024, with the 3% rate continuing to apply, provided completion occurs without contract variations or assignment of rights. For the vast majority of 2026 purchases, the 5% rate applies, and budgeting for it is part of the buying-side tax decision.
{{INSET-CODE-2}}
First-time buyer relief in 2026 allows UK first-time buyers to pay 0% SDLT on the first £300,000 and 5% on the portion between £300,001 and £500,000, with no relief above £500,000. The relief is reserved for buyers who:
Have never owned a residential property anywhere in the world
Are buying their first property as their main residence
Are buying a property that will be their main UK residence going forward
The practical effect for expat buyers is that first-time buyer relief is rarely available. The two main reasons:
A few narrow situations where relief may still apply:
These cases are rare and require careful planning. For most expat buyers, first-time buyer relief is not the right route, and the standard rates plus surcharges apply. For purchases over £500,000, first-time buyer relief is unavailable to anyone, UK resident or not.
The structure choice at purchase shapes the SDLT calculation, the ongoing tax position and the eventual exit. The three main routes:
{{INSET-CODE-8}}
The joint-purchase position is worth flagging for expat couples. Where one partner is UK resident and the other is non-resident, the 2% surcharge generally still applies to the whole purchase, because the non-resident status of any joint owner triggers the surcharge. Some structures (e.g. spouse as sole purchaser if the spouse is UK resident) can mitigate this, but they require careful planning around the wider tax position.
Limited company SPV purchases trigger the higher rates of SDLT for non-natural persons on properties over £500,000. The 15% flat rate applies in some narrow categories, but most genuine BTL SPV purchases fall under the standard residential rates plus the 5% additional dwelling surcharge, plus the 2% non-resident surcharge if the directors are non-resident. Whether the SPV is itself UK or offshore-incorporated also affects the position.
For SPV purchases over £500,000, ATED also enters the picture. ATED is an annual charge payable by companies, partnerships with at least one corporate member and certain collective investment schemes that own UK residential property over £500,000. The 2026/27 charge starts at £4,600 for properties between £500,000 and £1 million and rises to £303,450 for properties over £20 million. Most genuine BTL SPV cases qualify for ATED relief because the property is rented commercially to third parties, but the relief must be claimed each year via an ATED return filed by 30 April. ATED is therefore mostly a compliance cost on commercial-let SPV BTLs, not an actual tax cost. For SPVs holding a property used by the directors or connected persons, full ATED can apply, which is often the deciding factor against SPV ownership for personal-use UK property.
{{INSET-CODE-3}}
To illustrate how the bands and surcharges combine, here are worked examples for typical expat purchase prices in 2026.
{{INSET-CODE-9}}
For a non-resident expat buying a £1,000,000 buy-to-let, the total SDLT runs to £111,250, of which £70,000 is the combined surcharge stack. That is the headline number most buyers underestimate at the start of the process.
The practical implication: SDLT should always be modelled at the planning stage, not at exchange. Buyers who add 7% to the purchase price as a rule of thumb for their total SDLT exposure usually land close to the right number for non-resident BTL cases.
The SDLT figure also affects the deposit and lending equation. A £600,000 BTL with £62,000 SDLT means the buyer needs roughly £180,000-£240,000 of deposit (30-40%), £62,000 of SDLT, plus fees, reserve and currency-conversion costs. The total capital outlay at completion can sit at £265,000-£335,000 on a £600,000 property. Borrowers who plan only the deposit often have to scramble for the SDLT amount in the final week, which is one of the most common sources of completion stress on expat cases.
SDLT is filed and paid within 14 days of completion. The return is filed by the buyer's solicitor in almost all cases, with the SDLT amount transferred at completion or shortly afterwards.
Key practical points:
For expat buyers funding from foreign currency, the SDLT amount needs to be converted to GBP and transferred in the same window as the deposit and lender funds. Currency conversion delays are a common preventable cause of SDLT payment slippage. Forward contracts on the SDLT amount can be used to lock the rate ahead of completion, which is sensible where the SDLT figure is large and the FX environment is moving.
{{INSET-CODE-4}}
The buying-side tax decision is a pre-exchange decision. Once contracts are exchanged, the structure choice has effectively been made and the SDLT band applies as it stands. The right time for the conversation is before any property is reserved, with three checkpoints in particular:
For portfolio investors, the tax conversation also needs to consider whether each new property fits inside the existing structure or triggers a new one. A single SPV holding multiple properties is usually cleaner than multiple SPVs each holding one property, but the right answer depends on lender criteria, refinance plans and exit horizons.
For returning UK residents, the timing of exchange and completion in relation to the 183-day test can move the SDLT bill by tens of thousands of pounds. Buyers who can plan completion to fall after they have re-entered UK residence under the SDLT test save the 2% surcharge in full, with no refund process required. Buyers who must complete before the threshold can pay the surcharge upfront and apply for the refund inside 12 months once the test has been crossed. Either route works; the choice usually depends on property availability, mortgage offer expiry and the buyer's flexibility on timing.

The buying-side tax position above is one part of a wider cross-border picture. SDLT and structure choice rarely sit in isolation, and Skybound's proposition is that the surrounding decisions can be handled together, in house, if the client wants that.
Around the tax decisions at the point of purchase, a cross-border buyer usually has:
None of this is required to complete a UK purchase. The tax position can be handled on its own, and many buyers will want only that. The point is that, for a client who would rather not assemble a separate specialist for each piece, Skybound can fold the property purchase into a single coordinated plan. It is an option the client can take up or leave. Tax is simply the clearest illustration of why the buying-side decision and the ownership-side decision belong in the same conversation: a structure chosen for the SDLT bill today shapes the rental and disposal tax for years afterwards.
Tax considerations when buying UK property from overseas are not about:
They are about:
Most expats only realise the size of the tax stack when the solicitor sends the SDLT figure days before completion. Those who plan it before the offer is made build the tax cost into the purchase price decision, which usually results in a different property being chosen, a different ownership structure being used, or both. The conversation usually returns more value than it costs, before any application is even submitted.

This article is for information purposes only and does not constitute financial, mortgage, tax or legal advice. Tax treatment depends on individual circumstances and may change in future. SDLT and surcharge rules apply differently in Scotland (LBTT) and Wales (LTT) and have their own non-resident treatment. Information about SDLT bands, surcharges and structure rules is correct at time of writing and should be verified against HMRC guidance before any property is purchased. Professional advice should always be sought before making property, finance or wider planning decisions.
Structure choice (personal vs joint vs SPV) and SDLT calculation interact. Getting the structure right at the buying stage is far cheaper than restructuring after completion.
