Do I need to send anything else for a stamp duty enquiry?

Introduction

People often want to know whether they have already provided enough information for a stamp duty land tax enquiry, or whether more documents are needed before proper advice can be given. This usually happens after an initial exchange where the client has sent some material but has not yet received a full legal or tax analysis.

The Question

A prospective client sent a brief follow-up asking whether the adviser now had everything needed to proceed with the matter. The underlying issue is a common one: when asking for SDLT advice, how can a buyer or property owner tell whether enough information has been provided for reliable advice?

Nick’s Explanation

The source material contains only a short administrative exchange and does not include Nick’s substantive tax analysis. The practical point arising from it is that a short message asking whether everything has been received does not itself establish the SDLT position. In most property tax matters, the adviser will need enough factual detail to identify the transaction, the property condition, the parties involved, the timing, and the relief or argument being considered.

In anonymised form, Nick’s position can be fairly summarised like this: the adviser acknowledged receipt of material, but the exchange did not yet set out the legal analysis. That means the answer depends on whether the factual evidence already supplied is sufficient to assess the relevant SDLT rules.

The Law

Stamp Duty Land Tax is charged under the Finance Act 2003. The amount due depends on the nature of the land transaction, the effective date, the chargeable consideration, and whether any relief, exemption or special treatment applies.

Where a person is seeking advice on whether a dwelling was unsuitable for use as a dwelling at the effective date, the issue usually arises under the residential SDLT rules in Finance Act 2003. The question is whether the property was residential property at the relevant time. HMRC and the courts look closely at the actual condition of the building on completion, not simply the buyer’s future plans or the fact that works were later carried out.

In cases involving alleged disrepair or uninhabitability, 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 fall outside the dwelling rules merely because it needs repair, modernisation or substantial works. The condition must be serious enough that, applying the legal test, it was not suitable for use as a dwelling at the effective date.

Analysis

Whether an adviser has “everything needed” depends on the issue being considered. In SDLT matters, that usually means the following.

First, the adviser needs the transaction basics. That includes the purchase price, completion date, whether the buyer already owned other property, and whether the purchase was by an individual, joint buyers, trustees or a company.

Second, the adviser needs the key documents. These commonly include the contract, transfer, completion statement, title documents, estate agent particulars, survey, photographs and any correspondence showing the condition of the property at the effective date.

Third, if the issue concerns whether the property was uninhabitable or not suitable for use as a dwelling, the adviser needs evidence directed to that legal test. It is not enough to say that the property was old, damaged, or in poor condition. Evidence should show what was wrong with the building at completion and why that condition meant it could not be used as a dwelling at that time.

Fourth, because the threshold is now relatively high after Mudan, the adviser will usually need clear and contemporaneous evidence. Useful material may include surveyor reports, lender retention letters, photographs taken at or before completion, contractor evidence, and documents showing the absence of essential facilities or serious structural or safety issues.

So, a brief email asking whether enough has been sent is not something that can answer the tax question by itself. The real issue is whether the factual record is complete enough to apply the law properly.

Outcome

The practical conclusion is that a client has provided “everything needed” only when the adviser has enough evidence to analyse the SDLT treatment with confidence. If the matter involves a claim that a property was not suitable for use as a dwelling, the evidence burden is significant and the legal threshold is high.

If only brief messages have been exchanged, that will rarely be enough on its own for a reliable conclusion.

Practical Steps

If you are trying to establish your SDLT position, it is sensible to gather and organise:

• the completion date and purchase price
• the contract, transfer and completion statement
• sales particulars and auction pack, if relevant
• survey reports and valuation reports
• dated photographs showing the property condition at completion
• quotes, invoices and contractor reports
• mortgage or lender correspondence, including any retention or refusal based on condition
• evidence of missing or unusable essential facilities, if that is part of the argument
• details of any other properties owned by the buyer at the effective date

It also helps to set out a short chronology explaining what the property was like on completion and what works were carried out afterwards. The key is to separate the condition on the effective date from later renovation decisions.

Conclusion

A short follow-up asking whether the adviser has enough information is a normal part of an SDLT enquiry, but the answer depends on whether the factual evidence is sufficient to apply the law. In uninhabitable property cases, that means detailed evidence is usually needed, and the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.
