Can you avoid the higher SDLT rates by disposing of an overseas property before buying a home in England?

Introduction

People often ask whether owning a home abroad affects Stamp Duty Land Tax (SDLT) when they buy a property in England. A common concern is whether the overseas property counts as an “additional dwelling”, and if so, whether selling or otherwise disposing of it before the purchase can prevent the higher rates from applying.

This question matters because the higher rates for additional dwellings can significantly increase the SDLT bill. The answer depends on the detailed wording of Schedule 4ZA to the Finance Act 2003, especially the rules on what counts as replacing a main residence and how a previous dwelling must be disposed of.

The Question

A buyer is planning to purchase a home in London. The buyer, or the buyer’s partner, already owns a residential property overseas. They want to know whether disposing of that overseas property before the English purchase would stop the new purchase being treated as an additional dwelling for SDLT purposes.

More specifically, they want to understand:

• whether an overseas property counts for the higher SDLT rates,
• what sort of disposal is needed,
• whether a sale is required or some other disposal may be enough, and
• whether HMRC might challenge a disposal carried out shortly before the purchase.

Nick’s Explanation

Nick’s key point was that the legislation does not generally say that the previous property must be sold in any particular way before it can count as having been disposed of. In anonymised form, his explanation was:

“There is no reference to how a property is disposed of other than if it is disposed to a connected party, such as a spouse or civil partner, then it will still count as an additional property. The other consideration is whether the disposal is being undertaken for the purposes of avoiding tax. If you dispose of the additional property, there is a small likelihood HMRC may ask about this disposal.”

He then highlighted the statutory test for when a purchased dwelling is treated as a replacement for the purchaser’s only or main residence under Schedule 4ZA.

The Law

The higher rates of SDLT for additional dwellings are found in Schedule 4ZA to the Finance Act 2003. Broadly, the higher rates can apply where, at the end of the day of the transaction, the purchaser owns an interest in more than one dwelling and the purchased dwelling is not a replacement for the purchaser’s only or main residence.

These rules can apply to dwellings anywhere in the world, not just in England or the UK. So an overseas home can be relevant when deciding whether the purchase is of an additional dwelling.

The main replacement rules appear in paragraph 3 of Schedule 4ZA. The extract referred to by Nick is paragraph 3(6), which provides:

“For the purposes of sub-paragraph (5) the purchased dwelling is a replacement for the purchaser’s only or main residence if—

(a) on the effective date of the transaction (“the transaction concerned”) the purchaser intends the purchased dwelling to be the purchaser’s only or main residence,

(b) in another land transaction (“the previous transaction”) whose effective date was during the period of three years ending with the effective date of the transaction concerned, the purchaser or the purchaser’s spouse or civil partner at the time disposed of a major interest in another dwelling (“the sold dwelling”),

(ba) immediately after the effective date of the previous transaction, neither the purchaser nor the purchaser’s spouse or civil partner had a major interest in the sold dwelling,

(c) at any time during the period of three years referred to in paragraph (b) the sold dwelling was the purchaser’s only or main residence, and

(d) at no time during the period beginning with the effective date of the previous transaction and ending with the effective date of the transaction concerned has the purchaser or the purchaser’s spouse or civil partner acquired a major interest in any other dwelling with the intention of it being the purchaser’s only or main residence.”

There are also anti-avoidance provisions within Schedule 4ZA. HMRC may look closely at arrangements that appear to have been entered into mainly to avoid the higher rates.

Analysis

The issue can be broken down into a series of steps.

1. Does the overseas property count at all?

   Yes, potentially. For SDLT higher-rate purposes, overseas residential property can count as another dwelling. So owning a property abroad can trigger the additional dwelling rules.

2. Will the English purchase be a replacement of a main residence?

   That depends on the facts. It is not enough simply to buy a property that will become the new home. The buyer must usually also have disposed of a previous only or main residence within the relevant three-year period and satisfy the other conditions in paragraph 3(6).

3. Does the legislation require a disposal by sale on the open market?

   Not in those exact terms. The legislation refers to disposal of a major interest. That is wider than a straightforward arm’s-length sale. In principle, what matters is whether there has been a real disposal of the relevant major interest and whether, immediately afterwards, the buyer and their spouse or civil partner no longer hold that major interest.

4. Are there disposals that do not work?

   Yes. As Nick noted, a disposal to a spouse or civil partner does not solve the problem in the way some people expect, because the legislation looks at the position of the purchaser together with their spouse or civil partner in relevant respects. Also, if the buyer still retains a major interest after the transaction, the replacement conditions may fail.

5. Does the old property need to have been the buyer’s only or main residence?

   Yes. This is crucial. Disposing of any additional property is not enough by itself. The dwelling disposed of must have been the buyer’s only or main residence at some point during the three years before the new purchase. If the overseas property was just an investment, holiday home, or another non-main residence property, disposing of it may not create a replacement of main residence for Schedule 4ZA purposes.

6. Could HMRC challenge a disposal?

   Possibly. If the disposal is genuine and fits the statutory wording, that is the starting point. But if the arrangement is artificial, circular, temporary, or mainly tax-driven, HMRC may ask questions and may consider whether anti-avoidance provisions apply.

7. What if the buyer is relying on the property being unsuitable for use as a dwelling?

   That argument is now more difficult than it used to be. In an uninhabitable or not suitable for use case, the condition thresholds are now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property will not fall outside the dwelling rules merely because it needs works or is in poor condition. The state of the property must meet a relatively demanding threshold.

Outcome

The practical conclusion is that disposing of an overseas property before buying in England can help only if the statutory replacement conditions are genuinely met. The key points are:

• an overseas dwelling can count for higher-rate SDLT purposes,
• the previous property must usually have been the buyer’s only or main residence,
• the legislation does not insist on one particular method of disposal in every case, but there must be a real disposal of the major interest,
• disposals involving a spouse or civil partner do not usually remove the problem, and
• HMRC may scrutinise arrangements that appear to be tax-motivated or artificial.

So the answer is not simply “sell any overseas property and the surcharge disappears”. It depends on whether the disposed-of property qualifies as the previous main residence under Schedule 4ZA.

Practical Steps

1. Identify every residential property interest owned by the buyer and, where relevant, by their spouse or civil partner, including overseas property.

2. Work out which property has actually been the buyer’s only or main residence as a matter of fact.

3. Check whether there has been, or will be, a genuine disposal of that previous main residence within the three years before the purchase.

4. Confirm that immediately after the disposal the buyer and their spouse or civil partner no longer retain a major interest in that dwelling.

5. Review whether any step in the arrangement could be seen as artificial or mainly tax-driven.

6. If considering an argument that a property is not suitable for use as a dwelling, assess it carefully against the higher threshold now indicated by Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

7. Keep evidence, such as residence history, disposal documents, and records showing the intended occupation of the new property as the only or main residence.

Conclusion

Owning an overseas property can trigger the higher SDLT rates when buying in England. Disposing of that property may prevent the surcharge only if it truly amounts to replacing a previous only or main residence under Schedule 4ZA to the Finance Act 2003. The detail matters, and the fact that a property is abroad does not take it outside the rules.
