Can you reclaim SDLT on an uninhabitable property or claim relief as a property trader?

Introduction

Buyers often ask whether Stamp Duty Land Tax (SDLT) can be reduced or reclaimed where a property needed major renovation, or where the purchase was part of a property trading business. These questions usually arise when a buyer has already paid the higher residential rates, or is close to completion and wants to know whether any relief applies.

The answer depends on the legal basis of the purchase. In broad terms, there are two different issues:

• whether the dwelling was suitable for use as a dwelling at the effective date of the transaction; and
• whether the buyer was acquiring the property in the course of a qualifying property trade, so that a specific SDLT relief may apply.

These are separate routes and they involve different tests, evidence and risks.

The Question

A buyer asked about two property purchases. One property had already been bought some years earlier and may have required renovation before it could be occupied by a tenant. Another property was close to completion. The buyer wanted to know:

• whether SDLT could be reduced or reclaimed because the earlier property was not habitable at purchase; and
• whether the imminent purchase should be treated as an investment purchase or as part of a property trading activity, and what difference that would make to SDLT.

Nick’s Explanation

Nick’s response drew a clear distinction between the two scenarios.

On the earlier purchase, his view was that if the property genuinely needed renovation before it could be inhabited, there may be a viable SDLT argument based on its condition at completion.

On the imminent purchase, he explained that the key question was the purpose of the acquisition. In substance, his point was:

• if the property is being bought as an investment and the higher residential rates apply, the issue is whether the property was habitable by a reasonable person at the date of purchase; and
• if the property is being acquired as part of a property trade, there may be SDLT reliefs for property traders, but those reliefs have conditions and important caveats.

That is the right starting point. SDLT treatment depends heavily on the facts, the buyer’s intention, and the condition of the property at the effective date of the transaction.

The Law

SDLT on land transactions is charged under the Finance Act 2003. For residential property, the rates and any higher rates depend on whether the subject matter of the transaction includes a dwelling.

The question whether a building is a “dwelling” is important because the higher rates for additional dwellings only apply if the property is residential. A building that is so defective that it is not suitable for use as a dwelling at the relevant date may fall outside that treatment.

The modern approach to suitability for use as a dwelling has been shaped by case law, including:

• PN Bewley Ltd v HMRC [2019] UKFTT 65 (TC)
• Fish Homes Ltd v HMRC [2020] UKUT 156 (TCC)
• Mudan and another v HMRC [2024] UKUT 307 (TCC)
• Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799

Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the threshold for showing that a property was not suitable for use as a dwelling is now relatively high. Ordinary disrepair, dated condition, missing fittings, or the need for renovation will often not be enough. The defects generally need to be serious enough that the property was not suitable for use as a dwelling at the effective date of the transaction.

Where the buyer is a property trader, separate relief provisions may be relevant under Schedule 6A to the Finance Act 2003, which deals with relief for certain acquisitions by property traders. Those rules are technical and contain detailed conditions about the nature of the trade, the intended resale, and occupation of the property.

Analysis

The two possible SDLT routes should be analysed separately.

First, consider the “not suitable for use as a dwelling” argument.

The legal test focuses on the condition of the property at the effective date of the transaction, usually completion. The question is not simply whether the property needed work, or whether a landlord would have renovated it before letting it. The real question is whether, viewed objectively, the property was suitable for use as a dwelling at that date.

After Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, this is a demanding test. A buyer will usually need strong evidence of serious defects. Examples that may be relevant include:

• lack of functioning basic services such as water, electricity or sanitation in a way that makes occupation unrealistic;
• serious structural failure;
• conditions creating real safety risks preventing ordinary residential occupation;
• official action or expert evidence showing the property could not reasonably be lived in.

By contrast, the following will often be insufficient on their own:

• old kitchens or bathrooms;
• cosmetic disrepair;
• damp, wear and tear, or outdated décor;
• a need for refurbishment before the property would be attractive to tenants or buyers;
• the buyer’s intention to undertake substantial works.

So, if the earlier property merely required renovation before letting, that fact alone does not establish that it was not suitable for use as a dwelling. The evidence would need to show something more serious.

Second, consider property trader relief.

If the buyer is acquiring the property as trading stock for resale in a genuine property trading business, relief may be available under the property trader rules. But this is not a general relief for anyone who buys, renovates and sells property. The statutory conditions matter. Among other things, HMRC will look closely at whether:

• the buyer is carrying on a genuine property trading business;
• the property is acquired exclusively for the purposes of that trade;
• the intention is resale rather than long-term investment;
• there is any non-qualifying occupation or use; and
• the transaction falls within the detailed limits of the legislation.

That means the buyer’s purpose at acquisition is critical. If the property is being held as an investment, rental asset, or possible mixed-purpose asset, that points away from trader relief. If it is truly being bought as stock for onward sale in a qualifying trade, the relief may be in point, subject to the statutory conditions.

Third, the fact that probate is involved does not itself determine SDLT treatment.

A probate sale may sometimes involve a property in poor condition, but there is no special SDLT rule simply because the seller is an estate or personal representative. The same legal tests still apply.

Outcome

The practical conclusion is this:

• For a past purchase, an SDLT reclaim based on the property being uninhabitable is only likely to succeed if there is strong evidence that the dwelling was not suitable for use as a dwelling at completion. Since Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the threshold is relatively high.
• For a current or future purchase, the buyer must first identify whether the acquisition is an investment purchase or a genuine trading purchase. If it is an investment purchase, the habitation test may matter. If it is a trading purchase, the property trader relief rules may need to be considered instead.

Practical Steps

A buyer assessing their SDLT position should gather evidence under the correct legal route.

• Establish the exact completion date, because the property’s condition must be tested at that date.
• Collect contemporaneous evidence of condition: survey reports, valuation reports, photographs, contractor reports, mortgage valuation comments, utility records, environmental reports and correspondence from the time of purchase.
• Identify whether the defects affected basic residential usability, not just marketability or rental readiness.
• Review the SDLT return already submitted, including whether higher rates were paid.
• For a trading argument, gather business records showing the nature of the trade, intention to resell, accounting treatment, financing structure and absence of investment use.
• Check the statutory conditions in Schedule 6A Finance Act 2003 carefully before assuming trader relief applies.
• If considering an amendment or reclaim, act within the relevant time limits and ensure the legal basis is clearly defined.

Conclusion

A property that needs work is not automatically outside residential SDLT. The present legal position sets a relatively high bar for showing that a dwelling was not suitable for use as a dwelling. If the purchase was instead part of a genuine property trading business, the correct question is whether the specific property trader relief rules apply. The right answer depends on the buyer’s purpose and the evidence available at the time of completion.
