Non-UK residents buying residential property in England or Northern Ireland pay a 2% SDLT surcharge on top of standard rates — and, if it's not a main residence, on top of the additional-property 5% surcharge too. That's up to 19% effective SDLT at the top band. This page shows how the surcharge is calculated, how the SDLT-specific residence test works (the 183-day test — different from the income-tax SRT), and how buyers who move to the UK within 12 months of completion reclaim the surcharge.

The 2% surcharge — what it is

Since 1 April 2021, non-UK residents purchasing residential property in England and Northern Ireland pay a 2% SDLT surcharge on top of the standard rates that would otherwise apply. It applies to individuals, trusts, and companies. It applies to freehold and leasehold. It applies whether the property is a main residence or an additional property. It stacks with the 5% additional-property surcharge where both apply.

The maximum effective SDLT rate for a non-UK-resident buyer of an additional residential property in the top band (above £1.5M) is 19% — 12% standard + 5% additional-property + 2% non-resident.

The SDLT residence test — it's not the SRT

SDLT has its own residence test, distinct from the statutory residence test (SRT) used for income tax. Do not assume you pass the SDLT test just because you pass the SRT.

The rule

You are UK-resident for SDLT if you have been present in the UK for at least 183 days in the 12 months ending on the effective date of the transaction (usually completion date). Fewer than 183 UK days and you are non-UK-resident, and the 2% surcharge applies.

What counts as a "day"

You count a day if you were physically present in the UK at midnight — the end-of-day rule. Arrive at Heathrow at 11 pm and leave at 2 am the next day, you've counted one UK day. Arrive at 1 am and leave at 11 pm the same day, you've counted zero UK days.

This is a mechanical, factual test — HMRC accepts travel records, boarding passes, employer records, or utility bills as evidence. The onus is on the buyer to demonstrate UK presence if the count is contested.

Which 12 months?

The 365 days immediately before the effective date of the transaction. If completion is on 15 September 2026, count your UK days between 16 September 2025 and 15 September 2026 inclusive.

Joint purchases — one non-resident triggers the surcharge

If any purchaser fails the 183-day test, the whole transaction attracts the 2% surcharge. Married couples and civil partners are treated as a single unit for the test — both must satisfy the 183-day rule for the surcharge to be avoided.

This catches out UK-resident buyers married to non-UK- resident spouses. Even if only the UK spouse's name is on the deeds, the surcharge applies because the marriage creates joint interest for SDLT.

Corporate buyers — the residence test for companies

A company is UK-resident for the SDLT surcharge if it is either UK-incorporated OR (if incorporated overseas) centrally managed and controlled from the UK. Central management and control is a case-by-case analysis focused on where board decisions are made. Ownership doesn't determine residence — a UK-incorporated company owned by overseas shareholders is UK-resident.

Non-UK-resident companies buying UK residential property typically face a stack of: 17% corporate flat rate (above £500k) + 2% non-resident surcharge + 5% additional-property surcharge = up to 24% effective rate. This is deliberate policy to steer overseas capital into corporate structures that pay Annual Tax on Enveloped Dwellings (ATED) rather than escaping the residential-purchase regime.

Reclaiming the surcharge — becoming UK-resident within 12 months

A buyer who pays the 2% surcharge at completion but then becomes UK-resident within 12 months of the effective date can reclaim the surcharge. The reclaim path is well- established and specifically legislated.

Eligibility for the reclaim

You must be present in the UK for at least 183 days during any continuous 365-day period that:

• Begins after the effective date of the transaction, AND
• Ends within 12 months of the effective date

Once the 183-day threshold is hit within that window, the right to reclaim crystallises. The claim itself must be filed within 2 years of the effective date (an important practical deadline).

How to file the reclaim

Amend the original SDLT return (form SDLT4 for the surcharge component) with evidence of UK presence. Suitable evidence: UK employer contract, UK utility bills, UK bank statements, travel records, GP registration, electoral roll. HMRC typically processes the reclaim within 15 working days.

The reclaim is often meaningful — on a £750k purchase, the 2% surcharge is £15,000. Buyers who move to the UK within 12 months of completion should treat the reclaim as standard.

Worked examples

Example 1 — Overseas buyer, main residence, £500,000

Aisha lives in Dubai, has spent 45 days in the UK in the last 12 months (visits and business). She buys a £500,000 London flat as her intended main residence when she relocates in October 2026.

• Standard SDLT on £500k main residence: £15,000
• Non-UK-resident surcharge (2% × £500k): £10,000
• Total at completion: £25,000
• Once Aisha is present in the UK for 183 days within any 365-day period starting after completion (achieved around late April 2027 if she moves in October 2026), she can reclaim the £10,000.

Example 2 — Overseas buyer, additional property, £750,000

Michael lives in Singapore permanently. He buys a £750,000 London flat as an investment (already owns his main home in Singapore). No plans to move to the UK.

• Standard SDLT on £750k: £25,000
• Additional-property surcharge (5% band-by-band): £32,500
• Non-UK-resident surcharge (2% × £750k): £15,000
• Total at completion: £72,500
• Effective rate: 9.67%. No reclaim available — Michael has no plans to become UK-resident.

Example 3 — Joint purchase, one UK-resident spouse, one non-resident

Sarah lives in the UK. Her husband David works in Zurich and has spent 60 days in the UK in the last 12 months. They jointly buy a £600,000 main-residence family home.

• Standard SDLT on £600k main residence: £20,000
• Non-UK-resident surcharge (2% × £600k): £12,000 — David's non-residence triggers the surcharge on the whole transaction
• Total at completion: £32,000
• Reclaim path: if David then moves to the UK and clocks 183+ days within 12 months of completion, they can reclaim the £12,000.

Example 4 — Marginal case, exactly 183 days

Robert works internationally. He counts 183 UK days exactly in the 12 months before completion. He passes the test — the surcharge does not apply. If Robert had counted 182 days, the £X × 2% surcharge would apply. Marginal buyers should keep meticulous travel records and, if possible, time the effective date to fall after they hit 183 days.

Timing the effective date to avoid the surcharge

If you are approaching the 183-day threshold, delaying completion by a few weeks can be worth thousands of pounds in avoided surcharge. Practical steps:

• Track your UK day-count meticulously with a calendar and boarding passes.
• If completion is scheduled while you're still under 183 days but you'll cross the threshold within a few weeks, negotiate a later completion date.
• Remember: the test is 183 days in the 12 months ending on the effective date. Time you were in the UK over a year ago doesn't count.
• Every UK day within the window matters equally — a day in month 1 counts the same as a day in month 12.

Interaction with other SDLT surcharges

Non-resident and additional-property surcharges stack on top of standard rates. Non-resident also stacks with corporate rates (17% flat rate on residential over £500k). It does NOT stack with the first-time buyer relief — FTB relief is lost entirely if the buyer already owns any residential property in the world, and (for non-residents) the 2% surcharge applies to the pre-relief SDLT position.

Effective rate table for a non-UK-resident buyer:

Slice	Main residence (%)	Additional property (%)
£0-£125k	2%	7%
£125k-£250k	4%	9%
£250k-£925k	7%	12%
£925k-£1.5M	12%	17%
Above £1.5M	14%	19%

Practical planning for non-UK-resident buyers

1. Model the total cost including surcharge before making an offer. The 2% surcharge is £15k on £750k — enough to change the buying decision on marginal purchases.
2. Plan the reclaim path if you're relocating. If UK residence within 12 months is realistic, treat the surcharge as a temporary cash-flow item, not a permanent cost.
3. Time completion carefully if your day-count is close to 183.
4. Take specialist SDLT advice for corporate structures, trusts, or purchases via SPV — the interaction with the corporate flat rate and ATED requires case-by-case analysis.
5. Keep detailed travel records from the moment you begin considering a UK purchase. HMRC's expectation is that you can demonstrate every UK day.

Frequently asked questions

What is the non-UK resident SDLT surcharge?

2% on top of standard SDLT for buyers who are non-UK-resident under the SDLT 183-day test at the effective date. England and Northern Ireland only. Stacks with the 5% additional-property surcharge.

Who is 'non-UK resident' for SDLT?

A buyer present in the UK for fewer than 183 days in the 12 months ending on the effective date. This is a bespoke SDLT test — NOT the same as the income-tax statutory residence test (SRT).

How does the day-count test work?

Count days you were physically present in the UK at midnight during the 365 days ending on the transaction date. 183 or more = UK-resident. Fewer than 183 = non-resident, surcharge applies.

Can I reclaim the 2% surcharge?

Yes if you become UK-resident within 12 months of completion (183+ days in any continuous 365-day period starting after completion). File amendment within 2 years of the effective date. HMRC refunds within 15 working days typically.

Does the surcharge apply to joint purchases?

Yes if any purchaser fails the 183-day test. Married couples and civil partners are treated as a single unit — both must be UK-resident to avoid the surcharge.

Does the surcharge apply to Scotland or Wales?

No. SDLT (and the 2% surcharge) only apply in England and Northern Ireland. Scotland uses LBTT; Wales uses LTT. Neither has an equivalent non-resident surcharge currently.

What are the effective rates for non-UK-resident buyers?

2%, 4%, 7%, 12%, 14% on a main-residence purchase. 7%, 9%, 12%, 17%, 19% on an additional-property purchase. Highest SDLT profile in the UK regime.

Can a company be non-UK resident for SDLT?

Yes. Non-UK-resident if not UK-incorporated AND not centrally managed from UK. Companies pay 2% surcharge on top of the 17% corporate flat rate on residential over £500k — up to 24% effective on additional property.
