How do I ask for more information before advising on a stamp duty rebate?

Introduction

People often look for help with a possible stamp duty refund or rebate before they have set out the facts in full. In practice, the starting point is always the same: the adviser needs enough detail to identify what happened, which tax rules may apply, and whether there is any realistic basis for a reclaim.

This article explains how an initial enquiry about a possible stamp duty rebate is usually handled, what information matters, and how the legal analysis is built from the facts provided.

The Question

A prospective client arranged an initial call about a possible stamp duty rebate. Before giving substantive advice, the adviser asked for more information about the query so that the position could be understood properly.

In general terms, the issue is this: what information should someone provide when asking whether they may be entitled to a stamp duty refund, repayment, or amendment?

Nick’s Explanation

Nick’s response was brief but important in substance. He asked the prospective client to provide more information about the query before advice could be given.

That approach is correct. Stamp duty advice depends heavily on the exact facts. A person may describe the issue as a “rebate”, but in law the position could involve any of the following:

• an overpayment of SDLT on purchase;
• a refund of the higher rates for additional dwellings;
• a claim that the property was not suitable for use as a dwelling at the effective date;
• mixed-use treatment;
• multiple dwellings relief issues for earlier transactions;
• an amendment to an SDLT return; or
• a repayment claim made outside the normal amendment route.

Without the underlying facts, no reliable answer can be given. A proper adviser will usually ask for the purchase details, the SDLT return, the completion date, the property condition, and the reason the client believes too much tax was paid.

The Law

The main legislation is the Finance Act 2003, which governs Stamp Duty Land Tax in England and Northern Ireland. The legal position depends on the nature of the transaction and the relief or repayment being considered.

Commonly relevant parts of the legislation include:

• Finance Act 2003, section 42, on the requirement to deliver an SDLT return;
• Finance Act 2003, section 76, on amendment of a land transaction return;
• Finance Act 2003, Schedule 4ZA, on higher rates for additional dwellings;
• Finance Act 2003, Schedule 6B, where replacement of a main residence is in issue;
• Finance Act 2003, section 116, on the meaning of “dwelling”;
• Finance Act 2003, section 55, on the amount of tax chargeable.

In some cases, HMRC may also consider whether a repayment claim can be made outside a simple return amendment, depending on timing and the procedural route available.

Where the argument is that a building was uninhabitable or not suitable for use as a dwelling, the condition thresholds are now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That means a buyer should not assume that disrepair, lack of modernisation, or inconvenience will be enough. The legal test is stricter than many people expect.

Analysis

The reason an adviser asks for more information is that SDLT outcomes turn on specific facts. A proper analysis usually works in the following order.

First, identify the transaction. The adviser needs to know what was bought, when it completed, and the price paid. SDLT is assessed by reference to the effective date of the transaction, usually completion.

Second, identify what tax treatment was originally applied. That means checking the SDLT return and working out whether the purchase was treated as:

• residential;
• non-residential or mixed-use;
• subject to higher rates;
• eligible for any reliefs or exemptions.

Third, identify why the buyer says too much tax was paid. Different reasons lead to different legal tests. For example:

• If the complaint is about the 3% surcharge, the key question may be whether the buyer replaced a main residence within the statutory time limits.
• If the complaint is about property condition, the key question may be whether the building was truly not suitable for use as a dwelling at the effective date.
• If the complaint is about land or outbuildings, the issue may be whether the transaction was genuinely mixed-use.

Fourth, check evidence. A successful reclaim usually depends on documents, not just recollection. Relevant evidence may include:

• the SDLT5 certificate and filed return;
• completion statements;
• the contract and transfer;
• title documents and plans;
• survey reports;
• photographs and invoices;
• valuation material;
• evidence about occupation or sale of a previous home.

Fifth, check time limits. Some SDLT corrections are made by amending the return. Others may require a different procedural route. Delay can be fatal to a claim, so the completion date and filing date matter.

Finally, test the facts against current case law. This is especially important in “not suitable for use” cases. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the threshold is relatively high. Serious defects may still not be enough unless they truly prevent the property from being suitable for use as a dwelling at the relevant date.

Outcome

The practical answer is that no responsible adviser can confirm entitlement to a stamp duty rebate without first obtaining the facts and documents. An initial request for more information is not a delay tactic. It is the necessary first step in giving accurate tax advice.

If a person thinks they may have overpaid SDLT, the right approach is to set out the transaction clearly and provide the supporting paperwork. Only then can the adviser assess whether there is a genuine repayment route.

Practical Steps

If you want an informed view on a possible SDLT refund or rebate, gather the following before seeking advice:

• the completion date and purchase price;
• a copy of the SDLT return and SDLT5 certificate;
• the contract, transfer, and title plan if available;
• details of any other properties owned at the time of purchase;
• details of any sale of a previous main residence;
• survey reports, photographs, and repair evidence if condition is relevant;
• a short written explanation of why you think the SDLT was overpaid.

It also helps to explain exactly what type of reclaim you believe may apply. If you are unsure, describe the facts rather than guessing the legal label.

Where the argument is based on disrepair or alleged uninhabitability, assess the evidence carefully in light of Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. The threshold is now relatively high, so weak or borderline cases should be approached with caution.

Conclusion

Before advising on a stamp duty rebate, the key step is to obtain full facts and documents. SDLT claims are highly fact-sensitive, and the legal route depends on the exact nature of the transaction, the original return, the reason for the alleged overpayment, and the applicable time limits.
