Can you reclaim SDLT because a property was in poor condition when you bought it?

Introduction

Many buyers search for a stamp duty land tax (SDLT) refund after hearing that a property bought in poor condition may have been taxed incorrectly. The usual argument is that, at the date of purchase, the building was not suitable for use as a dwelling, so the residential SDLT rules should not have applied in the normal way.

This issue has generated a large number of claims and a substantial amount of litigation. It is important to approach it carefully. A buyer does not get a refund simply because a property needed work, was dated, or required renovation. The legal test is narrower than that, and the threshold for showing that a property was 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 Question

A reader asks whether a possible SDLT reclaim might be relevant where an adviser had suggested that buyers of residential investment properties with condition issues at the time of purchase could often recover overpaid stamp duty from HMRC.

Put more generally, the question is this: if you bought a residential property in England or Northern Ireland and it had serious defects or was in very poor condition on completion, can you reclaim SDLT on the basis that it was not a dwelling for SDLT purposes?

Nick’s Explanation

Nick’s core point was that some SDLT reclaims have been made where the property’s condition at the effective date of the transaction meant the dwelling was said not to be suitable for use as a dwelling. He referred to the interaction between the statutory rules in Finance Act 2003 and the case law, including HMRC v PN Bewley Ltd.

In anonymised form, his position was that where a claim based on property condition is legally and procedurally correct, HMRC may have to amend the SDLT treatment. That reflects the general principle that SDLT depends on the true legal character of the property at the effective date of the transaction, not simply on how the parties described it.

However, that proposition needs qualification. The existence of a valid legal route for some claims does not mean that most properties needing repair qualify. The more recent authorities, especially Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, show that the bar is high.

The Law

SDLT on land transactions in England and Northern Ireland is governed by Finance Act 2003. Whether the residential rates apply depends in part on whether the subject matter includes a “dwelling”.

The key statutory provision is Schedule 4ZA to Finance Act 2003, which states that a building counts as a dwelling if:

• it is used or suitable for use as a single dwelling, or
• it is in the process of being constructed or adapted for such use.

The phrase “suitable for use as a dwelling” has been considered in a number of cases. The question is an objective one, judged at the effective date of the transaction, usually completion. The tribunal and courts look at the actual physical state of the property and ask whether it was suitable for residential use as a dwelling at that time.

A leading authority is HMRC v PN Bewley Ltd [2019] UKUT 65 (TCC). That case confirmed that a property can fall outside the dwelling definition if, at the relevant date, its condition means it is not suitable for use as a dwelling.

But later cases have emphasised that this is not an easy test to satisfy. Most notably, the Court of Appeal in Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799 confirmed that the condition thresholds are now relatively high in uninhabitable or not suitable for use cases. Serious disrepair, age, lack of modern fittings, or the need for substantial works will not automatically prevent a building from being a dwelling for SDLT purposes.

Analysis

To work out whether an SDLT reclaim may exist, it helps to go through the issue in stages.

First, identify the relevant date. The condition of the property is tested at the effective date of the transaction, usually the completion date. Later works, later surveys, or later deterioration are not the legal test, although they may sometimes help evidence the earlier condition.

Second, distinguish between disrepair and genuine unsuitability for use as a dwelling. A property may be:

• old-fashioned,
• in need of refurbishment,
• missing some modern conveniences,
• subject to damp, leaks, or defective services, or
• unpleasant to live in without works,

and still remain suitable for use as a dwelling in law.

Third, consider whether the defects were so serious that the building could not realistically function as a dwelling at all. Examples sometimes argued in these cases include the absence of basic facilities, major structural failure, or conditions making occupation impossible or unsafe. Even then, the courts now apply a strict standard. The question is not whether the property was ideal, mortgageable, or attractive to occupy. It is whether it was objectively suitable for use as a dwelling.

Fourth, review the evidence that existed at the time. Relevant material may include:

• survey reports close to completion,
• photographs and videos showing the condition on purchase,
• contract papers and auction particulars,
• invoices or quotations demonstrating immediate remedial works,
• local authority notices, if any, and
• witness evidence from those who saw the property at the relevant time.

Fifth, apply the current case law cautiously. PN Bewley remains important because it recognises that some properties are so defective that they are not dwellings for SDLT purposes. But Mudan makes clear that the threshold is relatively high. In practice, many claims based only on poor condition, renovation need, or limited functionality are unlikely to succeed.

Sixth, keep the tax consequence in mind. If the property was not a dwelling at the effective date, that may affect whether residential rates applied and may in turn support an amendment or reclaim. But the exact outcome depends on the whole transaction structure, including whether the property was mixed-use, non-residential, or simply not within the dwelling definition for a particular SDLT provision.

Outcome

The practical answer is that a reclaim is possible in some property-condition cases, but only where the facts are strong. A property does not cease to be a dwelling merely because it was run down or required major refurbishment.

Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the condition thresholds in uninhabitable or not suitable for use cases are now relatively high. Anyone considering a reclaim should therefore assume that only genuinely severe cases are likely to justify a refund.

Practical Steps

If you want to assess your position, the sensible next steps are:

• check the SDLT return and the basis on which tax was originally paid;
• identify the exact completion date, because that is the critical date for the legal test;
• gather contemporaneous evidence of the property’s condition at that date;
• separate ordinary disrepair from defects that may have made residential occupation impossible in a legal sense;
• review the facts against HMRC v PN Bewley Ltd and Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799;
• consider whether the time limit for amendment or reclaim is still open; and
• obtain advice focused on the statutory test and the current case law, rather than on broad claims that any poor-condition property qualifies.

Conclusion

You may be able to reclaim SDLT if the property was truly not suitable for use as a dwelling when you bought it, but the legal test is demanding. After Mudan, most claims will turn on whether the evidence shows something more serious than disrepair or a need for renovation. The key question is the property’s objective suitability for residential use at completion.
