Does the 2% non-resident SDLT surcharge apply if one spouse lives abroad and the other is UK resident?

Introduction

Buyers often search for this issue when one spouse works overseas, the family remains in the UK, and a new home is being bought jointly. The main questions are usually whether the 2% non-UK resident SDLT surcharge applies and whether the higher rates for additional dwellings apply if the purchase is replacing a former main residence.

The important point is that SDLT has its own residence rules. Those rules are separate from the Statutory Residence Test for income tax and separate from treaty residence under a double taxation convention. In the right case, a buyer may be treated as non-UK resident for some tax purposes, but still avoid the SDLT non-resident surcharge because of the specific wording of Schedule 9A to Finance Act 2003.

The Question

A married couple are buying a UK dwelling jointly. One spouse has been living and working abroad for some time and may be resident overseas, or even treaty resident overseas, for direct tax purposes. The other spouse remains in the UK and will clearly satisfy the SDLT day-count test.

The couple also own another dwelling, but they previously sold what had been their family home and are now buying a new property intended to be the family’s main residence. The new purchase is expected to complete within 36 months of the sale of the former main residence.

The questions are:

• Does the 2% non-resident SDLT surcharge apply?
• Do the higher rates for additional dwellings apply?

Nick’s Explanation

Nick’s view was that the SDLT answer turns on the wording of the Finance Act 2003 schedules, not on the wider income tax residence analysis.

On the 2% surcharge, he explained that SDLT has a “self-contained residency test” in Schedule 9A Finance Act 2003. He pointed to the rule that where spouses or civil partners are joint purchasers, are living together, and one of them is UK resident for Schedule 9A purposes, the other is treated as UK resident as well.

In anonymised form, his conclusion was:

Where a married couple buy jointly and one spouse meets the UK residence test in Schedule 9A, paragraph 12 can treat the other spouse as UK resident in relation to the transaction. On those facts, the purchase is not a non-resident transaction, so the 2% surcharge does not apply.

On the higher rates for additional dwellings, Nick explained that the replacement of main residence exception can disapply the surcharge even if another property is still owned. His reasoning was that if the former main residence was sold within the three years before the new purchase, and the new dwelling is the replacement main residence, the higher rates should not apply.

In anonymised form, he said:

If the old main residence was disposed of within the previous 36 months and the new property is replacing it as the main residence, the higher-rates charge does not apply.

The Law

The relevant legislation is in Finance Act 2003.

For the 2% non-resident surcharge, the key provisions are in Schedule 9A:

• Paragraph 2(1): a transaction is a “non-resident transaction” if at least one purchaser is non-resident in relation to the transaction.
• Paragraph 3: an individual is non-resident unless they meet the statutory UK presence test for Schedule 9A.
• Paragraph 4(1): an individual is “UK resident” in relation to the transaction if present in the UK on at least 183 days during any continuous period of 365 days falling within the relevant period around completion.
• Paragraph 12: where joint purchasers are spouses or civil partners living together, and one is UK resident in relation to the transaction, the other is also treated as UK resident in relation to the transaction.

For the higher rates on additional dwellings, the relevant provisions are in Schedule 4ZA:

• Paragraph 3 sets out when Condition C is met, broadly meaning the purchased dwelling is not replacing the purchaser’s only or main residence and the purchaser has an interest in another dwelling.
• Paragraph 3(5) and (6) contain the replacement of main residence rules.
• Paragraph 3(6)(b) requires the previous main residence to have been disposed of within the three-year period ending with the effective date of the new purchase.

Where there is an argument that a property was so defective that it was not suitable for use as a dwelling, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That authority is relevant to “unsuitable for use” cases, but it does not alter the replacement of main residence rules discussed here.

Analysis

The analysis should be done in two separate parts.

First, consider the 2% non-resident surcharge.

1. Ignore, for this purpose, the wider question of whether the overseas spouse is UK resident under the Statutory Residence Test for income tax.
2. Ignore, again for this purpose, whether that spouse is treaty resident abroad under a double taxation convention.
3. Apply Schedule 9A Finance Act 2003 only.
4. Ask whether either purchaser is non-resident in relation to the transaction.
5. If one spouse clearly satisfies the 183-day UK presence test in the relevant Schedule 9A period, that spouse is UK resident for SDLT purposes.
6. If the buyers are spouses or civil partners, are buying jointly, and are living together, paragraph 12 applies.
7. Paragraph 12 then treats the other spouse as UK resident in relation to the transaction as well.
8. That means the transaction is not a “non-resident transaction”.
9. The result is that the 2% surcharge does not apply.

This is why the direct tax residence analysis may be interesting in a broader tax review, but it is not the deciding point for the SDLT surcharge. SDLT uses its own statutory test.

Second, consider the higher rates for additional dwellings.

1. Start by asking whether, at the end of the day of completion, the buyers will own an interest in more than one dwelling. If yes, the higher rates may potentially apply.
2. Then ask whether the new purchase is replacing an only or main residence.
3. That replacement test can still be met even if another dwelling is retained.
4. The legislation allows the exception where the purchaser, or the purchaser’s spouse or civil partner, disposed of a major interest in a former only or main residence within the previous three years.
5. If the sold dwelling was at some time during that three-year period the purchaser’s only or main residence, and the new dwelling is the replacement residence, the higher rates do not apply.

On the facts described, the former family home was sold less than 36 months before the expected completion of the new purchase. If the new dwelling is genuinely the replacement main residence for the family, that points strongly to the replacement exception applying.

It is also important to note that the replacement rules can work where the former residence was sold by one spouse and the new property is acquired by spouses jointly, provided the statutory conditions are met. The legislation expressly refers to a disposal by the purchaser or the purchaser’s spouse or civil partner.

Outcome

On the scenario described, the practical conclusion is:

• The 2% non-resident SDLT surcharge should not apply if the purchase is in joint names, the spouses are living together, and one spouse meets the Schedule 9A UK residence test.
• The higher rates for additional dwellings should not apply if the new property is replacing the former main residence and the old main residence was sold within the previous 36 months.

So, even where one spouse lives and works abroad, the SDLT result may still be that neither surcharge applies.

Practical Steps

Anyone assessing a similar purchase should work through the following points carefully:

1. Check that both spouses or civil partners are in fact joint purchasers on the contract and transfer.
2. Confirm that they are treated as living together for the purposes of paragraph 12 Schedule 9A FA 2003.
3. Count the UK-resident spouse’s days of presence in the relevant 365-day Schedule 9A period around completion to ensure the 183-day test is met.
4. Keep evidence of UK presence, such as travel records, work records, and other supporting documents.
5. Identify the date on which the former main residence was sold.
6. Check that completion of the new purchase falls within three years of that disposal.
7. Gather evidence showing that the sold dwelling had been the only or main residence and that the new dwelling is intended as its replacement.
8. Make sure the conveyancer applies the SDLT rules on the correct statutory basis when preparing the return.

If there is any suggestion that the new property is uninhabitable and therefore outside the residential rules, that needs separate and careful analysis. The bar for showing a property is not suitable for use as a dwelling is now relatively high after Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Conclusion

For SDLT, the overseas spouse’s wider tax residence position is not the main issue. The key point is that Schedule 9A has its own residence test, and paragraph 12 can treat both spouses as UK resident when they buy jointly and one spouse meets the UK day-count rule. If the couple are also replacing a former main residence within 36 months, the higher rates for additional dwellings should usually be switched off as well.
