Owning Property Abroad: Does It Affect Your UK Stamp Duty?
An overseas residential property counts for the additional dwelling surcharge test. If its value is £40,000 or more, you will pay the 5% higher rate on your UK purchase. Non-UK residents face a further 2% surcharge on top of that.

Key Takeaways
- •Overseas residential property worth £40,000 or more triggers the 5% UK additional dwelling surcharge.
- •Non-UK residents face an additional 2% surcharge on top, making a potential 7% total uplift on each band.
- •On a £300,000 UK purchase, the higher rate costs £20,000 vs £5,000 at standard rates.
- •If you sold the overseas property before or on completion of the UK purchase, the surcharge does not apply.
- •The non-resident surcharge can be reclaimed if you become UK resident within 24 months of completion.

The Overseas Property Rule
The additional dwelling surcharge, known formally as the Higher Rates for Additional Dwellings (HRAD), applies to any UK residential purchase where the buyer (or their spouse or civil partner) already owns another residential property worth £40,000 or more. Crucially, the legislation contains no geographic restriction: properties located anywhere in the world count for this test.
This means a holiday home in Spain, an inherited apartment in France, a rental property in Australia, or a family home in India will all potentially trigger the surcharge on a UK purchase, provided the property's market value is at or above the £40,000 threshold at the time of UK completion.
Consider a practical example: Priya grew up in India and her family owns a house there. She has been living and working in the UK for several years and wants to buy her first UK property for £280,000. Even though the Indian property is abroad, even though Priya has never lived there as an adult, and even though she does not consider it her home, it counts for the UK SDLT test. Provided the Indian house is worth £40,000 or more (almost certainly the case), Priya will pay the higher rates on her UK purchase.
The valuation test uses the market value of the overseas property, not the buyer's share of it, but the full property value. However, if the overseas property has been sold and legal title transferred before (or on the same day as) the UK completion, it no longer counts and the surcharge does not apply.
Legal basis: Finance Act 2003, Schedule 4ZA, paragraph 2 defines "major interest in a dwelling" without geographic restriction. HMRC guidance at SDLTM09800 confirms overseas properties count.
Who Is a Non-UK Resident
In addition to the 5% additional dwelling surcharge, buyers who are not UK resident at the time of purchase face a further 2% non-resident SDLT surcharge introduced in April 2021. The two surcharges stack, meaning you can pay both simultaneously.
Non-UK resident status for SDLT purposes is defined by a specific test: a buyer is non-resident if they have been present in the UK for fewer than 183 days in the 12-month period ending on the completion date of the transaction. This is a straightforward day-count test, not the statutory residence test used for income tax and capital gains tax purposes.
For joint buyers, the non-resident surcharge applies to the whole transaction if any one buyer fails the 183-day test. For companies, a different set of rules applies: broadly, a company is non-resident if it is not UK-controlled.
A common situation involves someone who has recently relocated to the UK for work and completes on a property purchase within their first few months here. Even if they plan to stay in the UK permanently, they are technically non-resident for SDLT purposes until they have accumulated 183 days in the country. The 2% surcharge applies but can be reclaimed once residency is established.
Day count: The 183-day test looks backwards from completion date, not forward. If you have recently moved to the UK and complete on a property before you have been here for 183 days, you are non-resident for SDLT purposes even if you intend to stay permanently.
Rate Scenarios
The table below shows all four possible combinations of residency status and property ownership, and the effective rate applied to each band of a residential purchase.
| Band | Standard (UK res, no overseas) | Higher (UK res, owns overseas) | Non-Res (no overseas) | Non-Res + Higher (non-res, owns overseas) |
|---|---|---|---|---|
| £0 – £125,000 | 0% | 5% | 2% | 7% |
| £125,001 – £250,000 | 2% | 7% | 4% | 9% |
| £250,001 – £925,000 | 5% | 10% | 7% | 12% |
| £925,001 – £1,500,000 | 10% | 15% | 12% | 17% |
| Above £1,500,000 | 12% | 17% | 14% | 19% |
Worked Examples
Both examples use a £300,000 UK residential purchase.
Example 1: Overseas Owner, UK Resident
Owns a holiday home abroad worth over £40,000. Has been UK resident for 183+ days. Higher rates apply; non-resident surcharge does not.
Example 2: Overseas Owner, Non-UK Resident
Same overseas property. Has been in UK fewer than 183 days in last 12 months. Both higher rates (+5%) AND non-resident surcharge (+2%) apply.
| Buyer Profile | SDLT on £300,000 |
|---|---|
| Standard buyer (UK resident, no other property) | £5,000 |
| UK resident with overseas property | £20,000 |
| Non-UK resident, no other property | £11,000 |
| Non-UK resident with overseas property | £26,000 |
Refund of Non-Resident Surcharge
The 2% non-resident SDLT surcharge is refundable if the buyer (or all buyers, in a joint purchase) becomes UK resident within 24 months of the completion date. This allows people who move to the UK shortly after buying to reclaim the surcharge once they meet the 183-day threshold.
To claim the refund, you must file an amended SDLT return within 12 months of completing the 183 days of UK presence. The refund covers only the non-resident surcharge (2%). The additional dwelling surcharge (5%) is not refundable via this mechanism.
Refund eligibility checklist
- • The purchase was subject to the non-resident surcharge
- • You (and all joint buyers) have been UK resident for 183+ days in any continuous 365-day period ending within 24 months of completion
- • You file the amended return within the statutory time limit
Note on the overseas property surcharge: The refund only covers the 2% non-resident element. If you still own the overseas property at the time of the UK purchase, the 5% higher rate surcharge is not refundable regardless of your residency status.
Forum Spotlight
These questions reflect discussions seen across UK property forums, particularly from overseas nationals buying their first UK property and expats returning to the UK. Answers reflect HMRC rules as of April 2026.
Someone asked on a UK property forum:
"I came to the UK from South Africa two years ago. My parents put my name on the family home back in Johannesburg for inheritance reasons. I have never lived there. Will that house affect my SDLT when I buy in the UK?"
Yes, it almost certainly will. The SDLT higher rate test applies to any residential property anywhere in the world where you have a beneficial interest, regardless of whether you live there or consider it your home. If the South African property has a market value of £40,000 or more (which is extremely likely for any family home in Johannesburg), the 5% additional dwelling surcharge applies to your UK purchase. The fact that it is a family home and you were added for inheritance purposes does not create an exemption. You should discuss with a solicitor whether it is possible to remove your name from the South African title before completing on the UK purchase.
Someone asked on a UK property forum:
"I am relocating to London from Hong Kong for a new job. I own a flat there. I will be buying a property in London almost immediately. What is my SDLT situation?"
You are facing two surcharges stacking together. First, because you own the Hong Kong flat (worth well above £40,000), the 5% additional dwelling surcharge applies. Second, because you will be completing in the UK before you have been here for 183 days, the 2% non-resident surcharge also applies. Together these add 7 percentage points to every SDLT band. However, the good news is that once you have spent 183 days in the UK (which will happen within your first year), you can reclaim the 2% non-resident element by filing an amended SDLT return. The 5% higher rate on the Hong Kong flat is not reclaimable unless you sell that flat.
Someone asked on a UK property forum:
"We are a British couple living in Spain. We sold our Spanish house last month and are now buying a home in the UK as we are moving back. Do we pay the higher rate?"
If the Spanish house is fully sold and legal title has transferred before (or on the same day as) your UK completion, you do not own any other property at that point and the higher rate surcharge does not apply. The test looks at what you own at the end of the day of completion, not at any earlier point. However, the non-resident surcharge may still apply if either of you has been in the UK for fewer than 183 days in the 12 months before UK completion. If you complete shortly after arriving back in the UK, count your days carefully or consider delaying completion until you pass the 183-day mark.
Someone asked on a UK property forum:
"My overseas property is a tiny rural cottage inherited from a grandparent. I genuinely do not know what it is worth. How does HMRC assess the value of an overseas property?"
HMRC expects buyers to self-assess the market value of any overseas property as part of the SDLT return. You are responsible for making a reasonable estimate based on local market conditions. If the property is genuinely very low in value and you believe it falls below £40,000, you would need to be able to substantiate that if HMRC questions it. For inherited rural properties in some regions, values can indeed be very low. A local estate agent's opinion or an independent valuation is the safest way to document the value, especially if you are filing on the basis of being below the threshold.
Common Mistakes
Buyers with overseas property connections frequently make these errors when purchasing UK residential property. Each mistake can result in underpaying SDLT, which HMRC will later seek to recover with interest and potentially penalties.
Assuming overseas properties are outside the SDLT rules
Many buyers are genuinely surprised to learn that a property in another country affects their UK stamp duty. The legislation explicitly includes properties worldwide, with no minimum ownership percentage required. This catches a significant number of international buyers, returning expats, and UK residents with family property connections abroad.
Confusing SDLT residency with statutory residence for tax purposes
The 183-day test for SDLT non-resident status is entirely separate from the statutory residence test that governs income tax and capital gains tax. A buyer who is UK tax resident under the statutory test may still fail the SDLT 183-day test if they have not been physically present in the UK for 183 days in the 12 months ending on completion day.
Not claiming the non-resident refund after becoming UK resident
Buyers who paid the 2% non-resident surcharge on purchase and subsequently became UK resident within 24 months are entitled to a refund of that 2%. Many people do not know about this refund and simply leave the money with HMRC. The claim must be filed within 12 months of completing 183 days of UK presence, so this deadline needs to be tracked actively.
Relying on exchange of contracts rather than legal completion abroad
In many countries, the process of selling property involves a preliminary contract followed by a final deed of sale. For UK SDLT purposes, what matters is whether legal title has transferred under the law of the relevant country. Simply having an agreement to sell, or even having exchanged, is not enough. The overseas property must be fully legally transferred before UK completion day.
Frequently Asked Questions
My overseas property is worth less than £40,000. Does it still count?
No. Properties with a market value under £40,000 are below the additional dwelling threshold and do not trigger the surcharge. If your overseas property is worth less than £40,000, you are treated as a standard buyer for SDLT purposes, assuming you have no other UK properties.
I sold my overseas property before completing on the UK purchase. Do I still pay the surcharge?
No, provided the overseas property was fully sold (legal title transferred) before or on the same day as the UK purchase completion. The test is applied at the end of the completion day. If you exchanged contracts on the overseas sale but completion has not yet occurred, the property still counts.
Does an overseas holiday home count?
Yes. Any residential property anywhere in the world counts if its value is £40,000 or more, including holiday homes, rental properties, and inherited overseas properties. The property does not need to be let out or used as a main residence. Its physical characteristics and value are what matter.
My overseas property is jointly owned with a family member. Does that count?
Yes. Part-owning a property (any share) triggers the surcharge provided your share's value is £40,000 or more. HMRC values your share by taking the overall property value and multiplying by your percentage ownership. There is no minimum ownership percentage threshold. Even a 5% share in a high-value property can trigger the surcharge.
