Do you pay the 5% SDLT surcharge if you buy in your sole name but your spouse owns the current home?

Introduction

This is a common Stamp Duty Land Tax question for married couples. A buyer may be purchasing a property in their sole name, may never have owned property before, and may even plan to move into the new property later. Even so, SDLT can still be affected by a spouse’s existing property ownership.

The key issue is that, for the higher rates of SDLT on additional dwellings, the law can treat spouses living together as connected in a way that overrides whose name is actually on the title. That often means the 5% higher rates surcharge is payable at completion, with a possible refund later if the old main residence is sold within the allowed period.

The Question

An individual is buying a residential property for £355,000 in their sole name. They have never previously owned property. They are married and live with their spouse, who part-owns the couple’s current home. That current home is expected to be sold within three years of the new purchase.

The buyer expects to be UK resident for SDLT purposes because they have spent more than 183 days in the UK in the relevant 12-month period. The new property may initially be let out, but the buyer intends to occupy it as their only or main residence within three years.

The questions are:

• Does the 5% higher rates surcharge apply at completion?
• Can it be reclaimed later if the current home is sold?
• Does the initial buy-to-let intention change the SDLT result?
• Does the 2% non-resident surcharge apply?

Nick’s Explanation

Nick’s reasoning was that the higher rates position turns mainly on the spouse’s ownership of the current home and whether that home is being replaced.

In anonymised form, his explanation was:

“Under Schedule 4ZA Finance Act 2003, the higher rates of SDLT apply where an individual, or their spouse if not permanently separated, owns another residential property at the effective date of the transaction.”

He also pointed to the replacement of main residence rules:

“If, within three years of acquiring a new property, you sell the previous main residence, you may reclaim the higher rates paid on the new property.”

On the buy-to-let point, Nick’s view was that an initial letting does not automatically block a refund, provided the new property is genuinely intended to become the buyer’s only or main residence within the relevant period.

He also noted that where the buyer has been present in the UK for more than 183 days in the relevant period, the 2% non-resident surcharge under section 75ZA should not apply.

The Law

The main rules come from the following provisions of the Finance Act 2003:

• Schedule 4ZA, which imposes the higher rates for additional dwellings
• Paragraph 9 of Schedule 4ZA, which contains the spouse or civil partner deeming rule
• Paragraph 3 of Schedule 4ZA, which deals with replacement of an only or main residence
• Section 75ZA, which imposes the 2% non-resident transaction surcharge

In broad terms, Schedule 4ZA applies the higher rates where, at the effective date of the transaction, the buyer has a major interest in another dwelling and the new purchase is not excluded as a replacement of the buyer’s only or main residence.

For married couples living together, paragraph 9 is especially important. It can treat one spouse’s property interest as relevant to the other spouse’s SDLT position, even where the purchase is in one name only.

The replacement of main residence rules can prevent the surcharge from applying in some cases, or allow a refund later where the old main residence is sold after the new purchase. The timing and factual use of the properties matter.

Where a buyer is UK resident for SDLT purposes, the 2% surcharge under section 75ZA does not apply.

Analysis

Step 1: Is the purchase residential SDLT?

Yes. The purchase is of a dwelling, so the residential SDLT rules apply.

Step 2: Does the spouse’s existing property matter even though the new purchase is in one name only?

Yes. If spouses are married and not permanently separated, paragraph 9 of Schedule 4ZA can treat the spouse’s ownership as relevant. So a buyer who has never owned property before can still be caught by the higher rates because their spouse owns a share in another dwelling.

Step 3: Does that mean the 5% higher rates surcharge applies at completion?

On these facts, yes. At the effective date of the purchase, the spouse still owns an interest in the current home. Because that home has not yet been sold, the new purchase is usually charged at the higher residential rates at completion.

Step 4: Can the surcharge be reclaimed later?

Usually yes, if the current home is the couple’s only or main residence and it is sold within three years after the new purchase, assuming the other conditions for replacement of main residence are met. In that situation, the buyer generally pays the higher rates first and then claims a refund from HMRC after the sale of the former main residence completes.

Step 5: Does it matter that the buyer plans to let the new property at first?

This point needs care. The legislation focuses on whether the new dwelling is acquired as a replacement for the old only or main residence. A temporary period of letting does not necessarily destroy the position if the property is genuinely intended to become the buyer’s only or main residence within the relevant period and in fact does so.

That said, the buyer should keep evidence of the intended move and the later occupation as a main residence. If the property remains an investment property and never becomes the buyer’s main home, the factual basis for a refund becomes weaker.

Step 6: Does the 2% non-resident surcharge apply?

Not if the buyer meets the SDLT residence test in section 75ZA. On the stated facts, presence in the UK for more than 183 days in the relevant 12-month period means the non-resident surcharge should not apply.

Step 7: What is the likely SDLT amount at completion?

Using the ordinary residential rates in force from 1 April 2025, a £355,000 purchase would normally attract SDLT of:

• 0% on the first £125,000 = £0
• 2% on the next £125,000 = £2,500
• 5% on the remaining £105,000 = £5,250

That gives standard residential SDLT of £7,750.

If the higher rates apply at completion, the surcharge is 5% of the full consideration:

• 5% of £355,000 = £17,750

Total SDLT at completion would therefore usually be:

• £7,750 standard SDLT
• plus £17,750 higher rates surcharge
• total £25,500

If the former main residence is sold within the permitted three-year period and the replacement conditions are met, the refundable element is generally the 5% surcharge of £17,750.

Step 8: Is first-time buyer relief available?

No, not on these facts. First-time buyer relief is not available if the purchase is subject to the higher rates for additional dwellings. In any event, the spouse rules and the existing ownership position mean the transaction is not treated in the same way as a straightforward first purchase by an unconnected individual.

Outcome

The practical result is:

• The 5% higher rates surcharge is likely to apply at completion because the buyer’s spouse still owns a share in the current home.
• The fact that the new property is bought in the buyer’s sole name does not avoid that result.
• If the current home is the couple’s main residence and it is sold within three years of the new purchase, the buyer should usually be able to claim a refund of the 5% surcharge.
• The initial buy-to-let intention does not automatically prevent a refund, provided the new property is genuinely intended to become, and does become, the buyer’s only or main residence within the relevant period.
• The 2% non-resident surcharge should not apply if the buyer meets the 183-day UK presence test in section 75ZA.

Practical Steps

If you are assessing a similar SDLT position, work through the following:

1. Confirm whether you are married or in a civil partnership and living together at completion.
2. Check whether either spouse owns a major interest in another dwelling at that date.
3. Identify whether the existing property is your current only or main residence.
4. Check whether that former main residence will be sold within three years after the new purchase.
5. Keep evidence showing the new property is intended to become your only or main residence, especially if it will be let temporarily first.
6. Calculate SDLT on the basis that the higher rates may be due upfront.
7. If the former main residence is later sold within time, submit a refund claim to HMRC for the surcharge element.
8. Check your SDLT residence status separately to see whether section 75ZA applies.

If the issue in your case is whether a property was uninhabitable or not suitable for use as a dwelling, note that the legal threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property will not be treated as unsuitable for use as a dwelling merely because it needs works or is in poor condition.

Conclusion

Where a married buyer purchases in their sole name but their spouse still owns the current home, the 5% SDLT surcharge will often be payable at completion. If that current home is the couple’s main residence and it is sold within three years, the surcharge can usually be reclaimed. An initial letting of the new property does not necessarily prevent that result, but the facts and evidence of intended main residence use matter.
