Can you reclaim the higher rate of SDLT if you buy a UK home while still owning property abroad?

Introduction

A common SDLT question is whether a buyer must pay the higher rates when purchasing a home in the UK if they already own property overseas, and whether that extra SDLT can later be reclaimed.

This issue often arises where someone has moved to the UK, still owns a former home abroad, and is now buying a main residence here. The answer depends on whether the overseas property counts as a major interest in another dwelling, whether the new UK purchase replaces a previous main residence, and whether the former main residence is sold within the relevant time limit.

The Question

A married couple are buying their first home in the UK. One spouse has never owned any property. The other spouse owns a former home overseas and also has a share in another overseas residential investment property.

The overseas home was previously the couple’s main residence before they moved to the UK. Since moving, they have rented in the UK. The overseas home has not yet been sold, although the buyer intends to sell it within three years after completion of the UK purchase. The couple have also stayed there occasionally during holidays.

The question is whether the UK purchase will be subject to the higher rates of SDLT at completion, and if so, whether a refund may be available once the overseas former home is sold.

Nick’s Explanation

Nick’s reasoning was that overseas property ownership is fully relevant for SDLT. A dwelling outside the UK can count in the same way as a UK dwelling when considering the higher rates for additional dwellings.

In anonymised form, his key point can be summarised like this: if one spouse already owns a dwelling anywhere in the world, and the couple are buying another dwelling together, the higher rates will usually apply on completion unless the purchase is treated as a replacement of their only or main residence.

He also explained that where the former main residence has not yet been sold by the completion date, the higher rates are commonly payable up front. A refund may then be claimed if that former main residence is disposed of within the permitted period and the other statutory conditions are met.

The fact that the buyer also owns a share in another overseas rental property is important because it reinforces that, at completion, the buyer already has an interest in another dwelling. However, for refund purposes, the key disposal is normally the former main residence, not the investment property.

Nick’s explanation also points toward the practical issue that occasional holiday use of the former home does not necessarily prevent it from having been the buyer’s previous main residence. What matters is the factual position: which property was genuinely occupied as the couple’s only or main residence before the move to the UK.

The Law

The higher rates of SDLT are set out in Schedule 4ZA to the Finance Act 2003.

In broad terms, the higher rates can apply where, at the end of the day of the transaction:

• the purchaser owns a major interest in another dwelling worth at least the minimum statutory amount, and
• the purchased dwelling is not a replacement for the purchaser’s only or main residence.

For married couples and civil partners living together, the rules generally aggregate their position. That means if either spouse owns another dwelling, the couple are usually treated together for the purposes of the higher rates.

Importantly, overseas dwellings are included. Ownership of residential property outside England and Northern Ireland can therefore trigger the higher rates.

A purchase can still qualify as a replacement of only or main residence if:

• the buyer previously disposed of a former only or main residence within the permitted period before the new purchase, or
• the buyer disposes of that former only or main residence within the permitted period after the new purchase and then claims a refund.

HMRC’s guidance on these rules appears in the SDLT Manual, including the sections dealing with higher rates for additional dwellings and replacement of only or main residence.

Analysis

Step 1: Does ownership of overseas property count?

Yes. The overseas former home counts, and so does the share in the overseas rental property, assuming each is a relevant major interest in a dwelling. SDLT does not limit this test to UK property only.

Step 2: Does it matter that one spouse has never owned property?

Usually not. Because married couples living together are generally treated as one unit for these rules, the ownership of one spouse can cause the higher rates to apply to a joint purchase.

Step 3: Will the higher rates be due on completion of the UK purchase?

Probably yes, if the overseas former home has not yet been sold by the completion date. At that point, the couple are buying a dwelling while one spouse still owns other dwellings, and the replacement condition has not yet been satisfied through an actual disposal.

Step 4: Can there later be a refund?

Potentially yes. If the overseas former home was genuinely the couple’s only or main residence before they moved to the UK, and it is sold within the statutory period after the UK purchase, a refund claim may be available.

Step 5: Does occasional holiday use of the overseas home within the last three years prevent a refund?

Not necessarily. Occasional visits do not automatically stop a property from having been the former only or main residence. The question is one of fact and degree. Relevant indicators include:

• where the couple lived on a settled basis before moving to the UK
• where their day-to-day life was centred
• the length and quality of occupation
• whether the property was their home rather than merely a holiday base or investment

If the overseas property was their true home before relocation, later short stays are unlikely by themselves to change that historic status.

Step 6: What is the significance of the other overseas rental property?

It is relevant at completion because it is another dwelling already owned by one of the purchasers. But for replacement-of-main-residence refund purposes, the critical disposal is usually the disposal of the former main residence. Selling the rental property instead would not normally produce the same refund result if that property was never the only or main residence.

Step 7: Is this a first-time buyer purchase?

No, not for SDLT relief purposes. First-time buyer relief is not available if any purchaser has previously owned a major interest in a dwelling anywhere in the world. So even though one spouse has never owned property, the other spouse’s existing ownership prevents the joint purchase from qualifying.

Step 8: Does anything about habitability affect this scenario?

Only if a buyer is arguing that an existing dwelling should be ignored because it is uninhabitable or not suitable for use as a dwelling. In that type of case, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. Ordinary disrepair, inconvenience, or the need for renovation will often not be enough. The property must fall short of suitability by a fairly demanding standard.

Outcome

On these facts, the UK purchase would usually be expected to attract the higher rates of SDLT at completion because one spouse already owns residential property overseas and the former overseas home has not yet been sold.

However, a refund may be available if the overseas home was in fact the couple’s former only or main residence and it is sold within the relevant statutory period after the UK purchase. The additional overseas rental property does not by itself prevent a refund, but it does mean the higher rates are likely to be payable initially.

Practical Steps

To assess the position properly, a buyer should:

• confirm exactly what interests are owned in each overseas property
• check whether the overseas former home was genuinely the only or main residence before the move to the UK
• collect evidence of occupation, such as utility records, tax records, immigration or relocation documents, and correspondence showing where the couple lived on a settled basis
• identify the expected completion date of the UK purchase and the likely sale date of the overseas former home
• ensure that any refund claim is made within HMRC’s time limits after the sale of the former main residence
• take advice before filing the SDLT return if there is any uncertainty about residence history or the nature of the overseas interests

Where overseas property is involved, it is especially important to review the facts carefully before completion, because the SDLT return may need to be filed and paid quickly.

Conclusion

If you buy a UK home while still owning a former home abroad, the higher rates of SDLT will often apply at completion. A later refund may still be possible if that overseas home was your previous only or main residence and you sell it within the permitted period. The fact that you also own another overseas rental property does not automatically block the refund, but it does make the initial higher-rate charge more likely.
