Can you claim first-time buyer SDLT relief if your spouse already owns a property overseas?

Introduction

Many buyers assume that if they are purchasing a home in their sole name, using only their own mortgage and savings, their spouse’s property history will not matter for Stamp Duty Land Tax (SDLT). That is a common source of confusion, especially where the spouse lives abroad and owns a property outside the UK.

The key question is whether a married buyer can still qualify for first-time buyer relief when their husband, wife or civil partner already owns a dwelling elsewhere in the world. A related question is whether a declaration saying the spouse has no involvement in the purchase can solve the problem.

In most cases, the answer is no. For SDLT purposes, the rules are strict, and overseas property ownership can prevent first-time buyer relief even where the UK purchase is in one spouse’s sole name.

The Question

A buyer is purchasing a UK dwelling for £450,000 in their sole name. The mortgage and purchase paperwork are also in that sole name, and the buyer intends to use a Lifetime ISA. The buyer has never owned property before.

However, the buyer’s spouse already owns a residential property in another country. That overseas property was bought many years ago, before the marriage, and the spouse will not be named on the UK title, mortgage or transfer documents.

The buyer wants to know:

• whether first-time buyer SDLT relief is still available, and
• whether a declaration confirming that the spouse has no ownership or beneficial interest in the new UK property would make any difference.

Nick’s Explanation

Nick’s view was that the buyer would not qualify for first-time buyer relief in this situation.

In summary, he explained that first-time buyer relief under Schedule 6ZA to the Finance Act 2003 depends on whether the purchaser is a first-time buyer, and the legislation looks at prior ownership of a major interest in a dwelling anywhere in the world. He also noted that HMRC treats spouses and civil partners as a single economic unit for these purposes.

His key point was that if a spouse already owns or has previously owned a dwelling overseas, that ownership prevents first-time buyer relief, even where:

• the UK purchase is in one spouse’s sole name,
• the other spouse is not on the title or mortgage, and
• the overseas property was bought before the marriage.

Nick also explained that a declaration of non-ownership does not alter the statutory test for first-time buyer relief. A declaration may matter in other contexts, but it does not rewrite the SDLT legislation.

He further noted that this does not automatically mean the 5% higher rates for additional dwellings apply. On the facts described, the issue is the loss of first-time buyer relief, not necessarily the additional dwelling surcharge.

The Law

SDLT is charged on land transactions under Part 4 of the Finance Act 2003. The core charging provisions include:

• section 42, which charges SDLT on land transactions,
• section 43, which defines a land transaction, and
• section 48, which deals with chargeable interests.

First-time buyer relief is contained in Schedule 6ZA to the Finance Act 2003. Broadly, relief is available only if the purchase meets the conditions in that Schedule, including that:

• the purchaser is a first-time buyer,
• the dwelling is intended to be the purchaser’s only or main residence, and
• the consideration does not exceed the relevant threshold.

The critical condition is that the purchaser must never previously have held a major interest in a dwelling anywhere in the world. Where there is more than one purchaser, all purchasers must satisfy that condition.

In practice, HMRC’s approach to married couples and civil partners is strict. The rules do not allow one spouse to claim first-time buyer relief where the other spouse has already owned residential property, even if that other spouse is not a legal purchaser in the new transaction. The legislation and HMRC guidance treat spouses and civil partners as connected in a way that prevents relief being claimed in these circumstances.

The fact that the earlier property is outside the UK does not help. The test is based on ownership anywhere in the world.

Analysis

Applying the rules step by step:

1. The UK purchase is a residential land transaction, so SDLT applies in the ordinary way.

2. The buyer is acquiring the property in their sole name and intends to live in it as their main residence. That would normally point towards first-time buyer relief being available.

3. However, the buyer is married, and the spouse already owns a dwelling overseas.

4. For first-time buyer relief, prior ownership of a major interest in a dwelling anywhere in the world is fatal to the relief. The overseas location of the spouse’s property does not take it outside the rule.

5. It does not matter that the spouse bought that property before the marriage. The relevant question is whether, at the effective date of the new transaction, the spouse has previously owned a major interest in a dwelling.

6. It also does not matter that the spouse is not on the mortgage, transfer or title. SDLT relief is determined by statute, not by a private declaration.

7. A declaration of non-ownership or non-involvement cannot convert a non-qualifying buyer into a qualifying first-time buyer for SDLT purposes.

So, on these facts, first-time buyer relief is not available.

There is a separate issue about the higher rates for additional dwellings. That is a different relief and surcharge regime from first-time buyer relief. Whether the 5% higher rates apply depends on the detailed wording of the higher rates rules in force at the effective date of the transaction. In the scenario described, Nick’s explanation was that the main issue was loss of first-time buyer relief, rather than an automatic charge to the higher rates merely because the spouse owns a foreign property.

Outcome

If you are married or in a civil partnership, and your spouse has already owned a dwelling anywhere in the world, you should generally assume that first-time buyer SDLT relief is not available, even if:

• you are buying alone,
• the property is only in your name,
• you alone are taking out the mortgage,
• you are using your own deposit or Lifetime ISA, and
• your spouse’s property was bought before the marriage and is overseas.

A declaration stating that your spouse has no ownership in the new property does not change that result.

Practical Steps

If you are trying to assess your SDLT position, take these steps:

1. Check whether you are legally married or in a civil partnership at the effective date of the transaction.

2. List any current or past ownership of dwellings by you and your spouse or civil partner, including property outside the UK.

3. Identify whether any such ownership amounted to a major interest in a dwelling.

4. Separate the first-time buyer relief question from the higher rates for additional dwellings question. They are related, but they are not the same test.

5. Ask your conveyancer or SDLT adviser to confirm the SDLT calculation using the rules in force on your completion date, especially where rates have changed.

6. If anyone suggests using a declaration of non-ownership to preserve first-time buyer relief, ask them to identify the exact statutory provision that allows that result. In most cases, there is no such provision.

Conclusion

A buyer cannot usually claim first-time buyer SDLT relief where their spouse already owns or has previously owned a dwelling anywhere in the world. It does not matter that the spouse lives abroad, bought the property before the marriage, or is not named on the UK purchase documents. A declaration of non-ownership does not override the Finance Act 2003.
