Can You Get a Stamp Duty Refund After Buying a Property?

Introduction

Many buyers ask whether they can reclaim Stamp Duty Land Tax (SDLT) after completion, especially if they think too much tax was paid or HMRC has rejected an earlier refund request. This usually happens where the buyer believes a relief should have applied, or where the property may not have qualified for the rate originally used.

The answer depends on the exact reason for the claim, the wording of the SDLT return, the time limits for amending or reclaiming tax, and the evidence available. If HMRC has already written back, the next step is usually to check whether the position is legally sound and whether any further challenge is realistic.

The Question

A buyer contacted a stamp duty adviser about a possible SDLT refund for a property bought in the previous year. The buyer had already sent correspondence to HMRC and had received a response. The issue was whether the matter was still open and whether anything further needed to be done in relation to the refund claim.

Nick’s Explanation

Nick’s reply was brief. In anonymised form, his view was that, based on the surrounding correspondence and messages, “everything is in hand”.

That kind of response suggests the adviser believed the case had already been progressed and that the immediate practical issue was not whether a refund was theoretically available, but whether any further action was still required. In SDLT matters, that usually means checking:

• whether a valid claim or amendment has already been submitted;
• whether HMRC has issued a decision or only requested more information;
• whether any statutory deadline is approaching; and
• whether the legal basis of the refund claim is strong enough to pursue further.

The Law

SDLT is charged under the Finance Act 2003. A buyer normally files an SDLT return and pays the tax shortly after completion. If the amount paid was wrong, the route to a refund depends on the reason.

The main legal routes commonly considered are:

• an amendment to the SDLT return within the statutory amendment window;
• a claim that too much tax was paid because the transaction was misclassified or a relief was missed;
• a repayment following replacement of a main residence, where the higher rates for additional dwellings were paid first and later become refundable; and
• in limited cases, overpayment relief or other corrective procedures, depending on the circumstances and timing.

Where the issue concerns whether a property was unsuitable for use as a dwelling at the effective date of the transaction, the legal test is now applied strictly. In uninhabitable or not suitable for use cases, the threshold is relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

That means a buyer will not usually succeed simply because a property needed repair, modernisation, decoration, or even fairly substantial works. The condition must be serious enough, in law, to take the property outside the concept of a dwelling for SDLT purposes on the relevant date.

Analysis

Whether a refund is available should be checked in a structured way.

1. Identify why the refund is being sought.

   A refund claim can arise for very different reasons. For example, the buyer may say:

   • the higher rates were paid but should not have been;
   • the property was not suitable for use as a dwelling;
   • mixed-use treatment should have applied;
   • a relief was overlooked; or
   • HMRC made an error in processing the return.

2. Check whether the claim was made in time.

   SDLT is heavily time-limit driven. If the return could still be amended when the issue was raised, that is often the simplest route. If not, the buyer may need to rely on a different statutory mechanism, if one is available.

3. Read HMRC’s latest letter carefully.

   HMRC’s response may be:

   • a refusal;
   • a request for more evidence;
   • an acknowledgement only; or
   • a closure of the matter.

   The wording matters because it affects what the buyer can do next and by when.

4. Test the legal basis against current authority.

   If the claim is based on property condition, the buyer should be cautious. After Mudan, the courts have confirmed that the bar is relatively high in uninhabitable cases. A property does not stop being a dwelling merely because it is old, damaged, or inconvenient to occupy. The question is whether, at the effective date, it truly failed the legal standard for a dwelling.

5. Consider the evidence.

   Refund claims usually stand or fall on evidence such as:

   • the contract and transfer;
   • the filed SDLT return;
   • completion statements;
   • valuation or survey evidence;
   • photos and reports showing condition at completion; and
   • all HMRC correspondence.

In this scenario, the adviser’s message indicates that the matter may already have been progressed through earlier correspondence and discussions. If so, the real issue is likely not starting a claim, but confirming status and making sure no deadline or response requirement has been missed.

Outcome

A buyer can sometimes obtain an SDLT refund after purchase, but only if there is a proper legal basis and the claim is made through the correct procedure within the relevant time limits.

If HMRC has already replied, the next step is to assess that reply against the original ground of claim. If the refund argument depends on the property being uninhabitable or not suitable for use as a dwelling, readers should be aware that the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Practical Steps

• Gather the SDLT return, SDLT5 certificate, completion statement, and HMRC letters.
• Identify the exact refund ground being relied on.
• Check the relevant statutory deadline for amendment, repayment, or appeal.
• If HMRC has refused the claim, review whether the refusal is legally correct and whether there is a right of review or appeal.
• If the argument concerns property condition, compare the facts carefully with current case law rather than assuming disrepair is enough.
• Keep a clear record of all correspondence and any evidence showing the position at the effective date of the transaction.

Conclusion

An SDLT refund is possible after completion, but it depends on the legal basis of the claim, the evidence, and the time limits. Where HMRC has already responded, the key task is to check whether the matter is already being dealt with and whether the claim remains strong in law. For uninhabitable property arguments, the courts now apply a relatively demanding test.
