Can You Reclaim SDLT Before You Complete a Property Purchase?

Introduction

A common question in property tax is whether Stamp Duty Land Tax (SDLT) can be reclaimed or reduced before a purchase has completed, especially where the buyer is gathering evidence about the condition of the property. This usually arises where a buyer thinks the dwelling may not be suitable for use as a residence at the effective date of the transaction and wants to know whether any relief or repayment might be available.

The short answer is that, where the buyer is still in the process of purchasing and completion has not yet taken place, there is no SDLT reclaim to make. The SDLT position is determined by the transaction that actually completes and the facts that exist at the effective date.

The Question

A buyer who is due to complete shortly has sent documents and photographs relating to the property, with further internal and electrical evidence still to come. The buyer wants to know whether, before completion, there is any basis to reclaim SDLT or reduce the SDLT position because of the property’s condition.

Nick’s Explanation

Nick’s core point was straightforward: if the buyer is still purchasing the property, there is no reclaim at this stage.

In anonymised form, his answer was essentially that the point should be ignored for now because the buyer is still in the process of buying the property, so there is “no reclaim”.

That reflects the practical tax position. A reclaim normally involves SDLT that has already been paid, or a return that has already been filed, and then corrected or amended if the legal basis exists. Before completion, there is not yet a completed land transaction on which a repayment claim can usually be based.

The Law

SDLT is charged under the Finance Act 2003 on land transactions. In broad terms, the liability arises when a chargeable transaction takes place, and the key date is usually the effective date of the transaction, which is commonly completion.

Whether a building counts as a dwelling for SDLT purposes depends on the statutory rules and the condition of the property at the effective date. In some cases, taxpayers have argued that a property was not suitable for use as a dwelling, with the result that different SDLT treatment should apply. That is a fact-sensitive issue.

However, 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. The courts have taken a stricter view of when disrepair or missing features are serious enough to prevent a property from being treated as residential accommodation.

Analysis

The position can be analysed in four steps.

First, if the purchase has not yet completed, there is generally no SDLT reclaim to make. A reclaim is usually relevant only after SDLT has been paid or a return has been submitted based on a completed transaction.

Second, if the buyer is really asking whether the property might qualify for different SDLT treatment on completion because it is allegedly uninhabitable, that is a different question from a reclaim. That issue depends on the condition of the property at the effective date and on the legal test for whether it is suitable for use as a dwelling.

Third, evidence such as photographs, survey material, electrical reports and internal condition reports may be relevant, but only if they show very serious defects existing at completion. Minor disrepair, dated condition, lack of modernisation, or repair needs will often not be enough.

Fourth, after Mudan, the bar is high. A buyer should not assume that missing utilities, poor condition, damaged interiors or renovation needs automatically mean the property is not suitable for use as a dwelling. The court has made clear that the test is demanding and that many properties in poor condition may still count as dwellings for SDLT purposes.

So, on these facts, the immediate answer is simple: there is no reclaim before completion. If the buyer wants to assess the SDLT treatment that may apply on completion, that requires a separate analysis of the property’s actual condition at that date and the current case law.

Outcome

If the purchase is still ongoing and completion has not happened, there is no SDLT reclaim available at that stage.

If the concern is whether the property might fall outside normal residential SDLT treatment because it is not suitable for use as a dwelling, that must be assessed by reference to the property’s condition at completion, and the legal threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Practical Steps

A buyer in this position should:

• confirm whether the issue is a true reclaim question or a pre-completion SDLT analysis;
• gather reliable evidence of the property’s condition as at completion, including surveys, specialist reports and dated photographs;
• focus on serious defects affecting actual suitability for residential use, not just repair or refurbishment needs;
• review the SDLT filing position only once the transaction has completed or is ready to complete;
• compare the facts carefully against the stricter approach taken in Mudan.

Conclusion

There is no SDLT reclaim to make before a property purchase completes. Any argument that a property is not suitable for use as a dwelling must be considered at the effective date of the transaction, and that argument is now harder to establish because the condition threshold is relatively high after Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.
