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 2% non-resident surcharge can be reclaimed if you spend 183 days in the UK in a 365-day period ending no later than one year after completion, by amending the return within 2 years 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 inherited a share of the family 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, her interest in it counts for the UK SDLT test. Provided her share is worth £40,000 or more, Priya will pay the higher rates on her UK purchase, unless her share is 50% or less and she inherited it within the last three years. That inherited-share exception applies to overseas property too (Schedule 4ZA, paragraphs 16 and 17).
The valuation test uses the market value of the interest the buyer holds, so where the property is jointly owned it is the buyer's share that must reach £40,000, not the value of the whole property. 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 17 extends "dwelling" to property outside England and Northern Ireland, counting the equivalent interest under local law. HMRC guidance at SDLTM09780 says the other dwelling can be anywhere in the world.
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. The exception is a married couple or civil partners living together: if one of you is UK resident, you are both treated as UK resident. For companies, a different set of rules applies: a company is non-resident if it is not UK resident for Corporation Tax, or if it is a UK close company controlled by non-residents.
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: When you file the return, only the days you have already spent in the UK count. If you have recently moved to the UK and complete on a property before you have been here for 183 days, you pay the 2% even if you intend to stay permanently. A day counts only if you are in the UK at the end of it (midnight). The days you spend here after completion can later earn a refund (see below).
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 to £125,000 | 0% | 5% | 2% | 7% |
| £125,001 to £250,000 | 2% | 7% | 4% | 9% |
| £250,001 to £925,000 | 5% | 10% | 7% | 12% |
| £925,001 to £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 every non-resident buyer, in a joint purchase) is present in the UK on at least 183 days in any continuous 365-day period that starts no earlier than 364 days before completion and ends no later than 365 days after completion. 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 amend your SDLT return within 2 years of the completion date (Finance Act 2003, Schedule 9A, paragraph 19). The deadline runs from completion, not from the day you reach 183 days. This refund covers only the non-resident surcharge (2%). The additional dwelling surcharge (5%) has its own, separate refund rule.
Refund eligibility checklist
- • The purchase was subject to the non-resident surcharge
- • You (and every non-resident joint buyer) were in the UK on 183+ days in a continuous 365-day period ending no later than 365 days after completion
- • You amend the return within 2 years of the completion date
Note on the overseas property surcharge: The residence refund only covers the 2% non-resident element. The 5% is refundable only under the replacement main residence rule: the overseas property must have been your only or main residence at some point in the three years before the UK purchase, the UK property must be your new main residence, and you must sell the overseas property within three years of completion. If the overseas property was a holiday home or a rental, the 5% is not refundable.
Forum Spotlight
These are paraphrased versions of questions that come up often on UK property forums, particularly from overseas nationals buying their first UK property and expats returning to the UK. Answers reflect HMRC rules as of September 2026.
A common question:
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 your share of the South African property has a market value of £40,000 or more, 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.
A common question:
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 in a 365-day period ending within a year of completion, you can reclaim the 2% non-resident element by amending your SDLT return within 2 years of completion. The 5% is reclaimable only if the Hong Kong flat was your main home at some point in the three years before the purchase, the London property becomes your new main home, and you sell the flat within three years of completing in London.
A common question:
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 you have been in the UK for fewer than 183 days in the 12 months up to UK completion. If you are married or civil partners and living together, one of you meeting the 183-day test is enough for both of you; unmarried joint buyers each need to meet it. 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.
A common question:
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 (the one exception is an inherited share of 50% or less, which is ignored for three years). 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 and then spend 183 days in the UK in a 365-day period ending within a year of completion are entitled to a refund of that 2%. Many people do not know about this refund and simply leave the money with HMRC. The return must be amended within 2 years of the completion date, 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 (unless you inherited a share of 50% or less within the last three years). 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. The exception is an inherited share of 50% or less, which does not count for three years from the inheritance.
