Do you pay the higher SDLT rates if your spouse inherited a small share in an overseas property worth under £40,000?

Introduction

A common SDLT question arises where a buyer or their spouse owns a small inherited share in another home, especially an overseas property. People often hear two different things: that they have lost first-time buyer relief, and that they must also pay the higher rates for additional dwellings. Those are separate issues, and they do not always lead to the same answer.

The key point is that owning another dwelling can prevent first-time buyer relief, but the 3% higher rates surcharge only applies if the statutory conditions are met. One of those conditions is that the other interest must usually have a market value of at least £40,000 at the effective date of the purchase.

The Question

A married couple are buying a residential property together. One spouse previously inherited a 50% share in a property outside the UK many years ago. The inherited share is said to be worth less than £40,000. Their conveyancer has suggested that the higher SDLT rates for additional dwellings apply, but HMRC indicated that only the standard residential rates should apply. Which view is correct?

Nick’s Explanation

Nick’s core reasoning was that the inherited overseas share should not trigger the higher rates if its market value is below £40,000 at the effective date of the purchase.

In anonymised form, his explanation was:

“If the spouse’s share is worth less than £40,000, it does not count as a qualifying major interest for the higher rates test. On those facts, the purchase should not attract the 3% higher rates surcharge. The standard residential SDLT rates should apply instead.”

He also identified the correct statutory source: Schedule 4ZA to the Finance Act 2003. In particular, paragraph 3(4) requires the buyer to have another major interest in a dwelling with a market value of £40,000 or more before the surcharge can apply.

That means the issue is not simply whether the spouse owns any part of another dwelling. The value of that interest matters.

The Law

SDLT on residential purchases is governed by Finance Act 2003. The higher rates for additional dwellings are contained in Schedule 4ZA.

For a standard single-dwelling purchase by an individual to fall within the higher rates rules under paragraph 3, several conditions must be met. The most relevant ones here are:

• the purchased dwelling must cost at least £40,000;
• at the end of the effective date, the purchaser must have a major interest in another dwelling;
• that other interest must have a market value of £40,000 or more; and
• the new purchase must not be a replacement of the purchaser’s only or main residence.

Paragraph 3(4) of Schedule 4ZA states that Condition C includes the requirement that the other interest has “a market value of £40,000 or more”. If that threshold is not met, the higher rates test fails.

Where spouses or civil partners buy together and are living together, SDLT generally treats them as one unit for these purposes. So one spouse’s existing property interests can affect the joint purchase. That is why the inherited share must be considered at all.

However, first-time buyer relief is a different relief with a different test. A person who has previously owned a major interest in a dwelling anywhere in the world will usually not qualify as a first-time buyer, even if that prior interest was inherited. So it is possible to lose first-time buyer relief but still avoid the higher rates surcharge.

Analysis

Step one is to separate the two SDLT issues:

• first-time buyer relief; and
• higher rates for additional dwellings.

They are often confused, but they are not the same.

On first-time buyer relief, the couple are unlikely to qualify if one spouse has previously owned a major interest in a dwelling, including an inherited share in an overseas residential property. That prior ownership is usually enough to prevent the relief.

On the higher rates surcharge, the question is narrower. The issue is whether, at the end of the effective date of the purchase, the spouse has another major interest in a dwelling with a market value of at least £40,000.

On the facts given, the inherited 50% share is worth less than £40,000. If that valuation is correct at the effective date, paragraph 3(4) is not satisfied. That means the surcharge should not apply.

It does not matter that the property is overseas. Overseas dwellings can count for SDLT surcharge purposes. What matters here is that the value of the spouse’s interest is below the statutory threshold.

It also does not matter that the interest was inherited many years ago, except insofar as the current market value must be tested at the relevant date. The key valuation point is the market value of that spouse’s share at the effective date of the new purchase, not the historic probate value and not the value of the whole property unless that is also the value of the acquired interest.

If the spouse’s share were actually worth £40,000 or more, the analysis could change. In that case the higher rates might apply unless the purchase was replacing an only or main residence. But on the stated facts, where the inherited share is below £40,000, the statutory test for the surcharge is not met.

This is not an “uninhabitable property” case, but for completeness, readers sometimes ask whether poor condition can take a property outside the dwelling rules. The threshold for showing that a property is not suitable for use as a dwelling is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That line of argument would not usually be needed where the £40,000 value threshold already resolves the surcharge issue.

Outcome

If one spouse owns an inherited 50% share in an overseas dwelling and that share is worth less than £40,000 at the effective date of the UK purchase, the 3% higher rates for additional dwellings should not apply under Schedule 4ZA Finance Act 2003.

However, first-time buyer relief will usually still be unavailable because of the earlier ownership of a dwelling interest.

So the practical result is usually:

• no first-time buyer relief; but
• standard residential SDLT rates only, not the higher rates surcharge.

Practical Steps

If you are assessing a similar case, the sensible steps are:

• confirm whether the buyers are spouses or civil partners living together, because one person’s property interests may be attributed to the joint purchase;
• identify exactly what interest is owned in the other property, including whether it is a freehold or leasehold interest and the percentage share;
• obtain evidence of the current market value of that person’s actual share at the effective date of the new purchase;
• separately check whether first-time buyer relief is lost because of prior ownership anywhere in the world;
• check whether the purchase is a replacement of an only or main residence, if relevant; and
• make sure the SDLT return reflects the correct treatment under Schedule 4ZA.

Where there is disagreement, it helps to point directly to paragraph 3(4) of Schedule 4ZA and the requirement that the other interest must have a market value of £40,000 or more.

Conclusion

A small inherited share in an overseas property can stop first-time buyer relief, but it does not automatically trigger the higher SDLT rates. If the spouse’s share is worth less than £40,000 at the effective date, Schedule 4ZA normally prevents the surcharge from applying. In that situation, the usual outcome is standard residential SDLT rates without first-time buyer relief.
