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 — and non-UK residents face a further 2% surcharge on top.

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.
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 — 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.
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.
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.
