Can You Reclaim SDLT While You Are Still in the Process of Buying a Property?

Introduction

A common question in Stamp Duty Land Tax (SDLT) cases is whether a buyer can reclaim tax during the purchase process, rather than after completion. This usually comes up where the buyer thinks a relief or exemption may apply, or where they believe the property should not attract the higher amount of SDLT first expected.

The short answer is that if the purchase has not yet completed, there is generally nothing to reclaim. SDLT is charged on a land transaction once the transaction has completed, and any repayment issue normally only arises after tax has actually been paid.

The Question

A buyer is in the course of purchasing a property and wants to know whether SDLT can be reclaimed before the transaction has completed.

Nick’s Explanation

Nick’s answer was brief and clear: if the buyer is still in the process of purchasing, there is no reclaim.

In practical terms, that is because a reclaim depends on SDLT having been paid in the first place. If completion has not yet taken place, the SDLT position usually remains prospective rather than final.

The Law

SDLT is governed principally by the Finance Act 2003. In broad terms:

• SDLT applies to chargeable land transactions.
• The effective date of the transaction is usually the completion date, unless there has been substantial performance earlier.
• A land transaction return is generally required after the effective date if the transaction is notifiable.
• Any claim for repayment or amendment normally follows submission of the return and payment of the tax.

This means there is a clear distinction between:

• arguing before completion that the correct SDLT treatment should be applied in the return from the outset, and
• reclaiming SDLT after completion where too much tax has already been paid.

Analysis

The position can be understood in a few steps.

1. First, ask whether the transaction has completed. If it has not, the SDLT liability may not yet have arisen in its final form.

2. Second, ask whether any SDLT has actually been paid. A reclaim is only relevant where tax has been overpaid.

3. Third, if the buyer believes a relief, exemption or lower rate applies, that point should usually be addressed before filing the SDLT return, so that the correct amount is paid at the outset.

4. Fourth, if completion has already taken place and too much SDLT was paid, the buyer may then need to consider an amendment, overpayment relief, or another statutory repayment route depending on the facts and timing.

So, where a person is still buying and has not yet completed, the issue is generally not a reclaim issue. It is a question of getting the SDLT treatment right before submission of the return.

If the underlying concern is whether the property is 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. A property will not fall outside the dwelling rules merely because it needs repair, modernisation or works before occupation. The condition must be serious enough to meet the stricter approach confirmed by the Court of Appeal.

Outcome

If the purchase is still ongoing, there is usually no SDLT reclaim available because there has not yet been a completed transaction giving rise to an overpayment. The practical issue is to determine the correct SDLT treatment before completion and filing.

Practical Steps

• Check whether the transaction has completed or has been substantially performed.
• Confirm whether any SDLT return has been filed and whether any SDLT has actually been paid.
• Identify the exact reason why a lower SDLT amount is thought to apply, such as a relief, exemption, replacement of main residence issue, or non-residential or mixed-use treatment.
• Review the contract, title documents and property condition evidence before filing the return.
• If the issue concerns habitability, assess the facts carefully against the current high threshold following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.
• If completion has already happened and too much tax was paid, consider whether the return can still be amended or whether another repayment mechanism may apply.

Conclusion

A buyer who is still in the process of purchasing a property cannot usually make an SDLT reclaim, because a reclaim depends on SDLT having been paid already. Before completion, the focus should be on making sure the right SDLT analysis is used from the start.
