How long does an SDLT amendment or repayment claim usually take?

Introduction

People often want to know how long HMRC will take to deal with a Stamp Duty Land Tax (SDLT) amendment or repayment claim after it has been submitted. This commonly comes up where a buyer believes too much SDLT was paid, for example because part of the purchase price may properly relate to removable items rather than the land transaction itself.

The answer is that there is no fixed statutory turnaround time for HMRC to issue a repayment. In practice, timing varies depending on the nature of the claim, the quality of the evidence provided, and whether HMRC decides to make further enquiries.

The Question

A buyer had instructed an adviser to review a possible SDLT reclaim. The review included a chattels point, with particular attention being given to items such as carpets and a jacuzzi. After the claim was submitted, the buyer asked how long the submission and any potential SDLT repayment were likely to take.

Nick’s Explanation

Nick’s explanation was short and practical. In anonymised form, his answer was:

“It usually takes between 4 to 12 weeks, but sometimes it can take longer. Generally, it is around 6 weeks.”

That is a fair summary of the usual real-world position. Some straightforward amendments are processed relatively quickly. Others take longer, especially where HMRC wants to check whether the claim is properly supported.

Nick had also indicated that the chattels aspect needed closer review, particularly in relation to specific household items. That is important because repayment timing often depends on whether the underlying technical argument is clear, properly evidenced, and consistent with SDLT law on chargeable consideration.

The Law

SDLT is charged under the Finance Act 2003. Broadly, tax is payable on the chargeable consideration given for a land transaction. The key issue in many repayment claims is whether part of the amount paid should be excluded because it relates to items that are not part of the land.

In broad terms:

• SDLT applies to chargeable consideration for the acquisition of land.
• If a buyer separately pays a justifiable amount for removable chattels, that amount may fall outside the SDLT calculation.
• If figures are inflated, artificial, or not properly evidenced, HMRC may reject the claim or open an enquiry.

Where a return has already been filed, an amendment or reclaim is usually made by amending the SDLT return within the statutory amendment window, or in some cases by making a repayment claim on another available basis if the legal conditions are met.

There is no general rule in the legislation that HMRC must process every SDLT repayment within a set number of weeks. Administrative timescales are therefore a matter of HMRC practice rather than a guaranteed legal deadline in most routine cases.

Analysis

In practice, the likely timeline depends on several stages.

First, the claim has to be prepared and submitted correctly. If the argument concerns chattels, the figures need to be realistic and supported by evidence such as the contract, completion statement, fittings and contents form, correspondence, photographs, valuations, or other material showing what was actually purchased and for how much.

Second, HMRC has to process the amendment or claim. If the submission is straightforward and internally consistent, repayment may be issued without much delay.

Third, HMRC may decide to ask questions. This is more likely where:

• the amount attributed to chattels appears high;
• the items look more like fixtures than removable chattels;
• the paperwork was unclear at the time of purchase;
• the claim appears to have been made after a retrospective reallocation of the price.

Fourth, if HMRC opens an enquiry or asks for supporting evidence, the timetable can extend well beyond the usual estimate. A claim that might otherwise have been dealt with in a few weeks can take several months.

So, while a rough expectation of around 6 weeks may be sensible for a routine case, a range of 4 to 12 weeks is more realistic, and longer delays are possible.

If the wider issue in a case is not chattels but whether a dwelling was uninhabitable or not suitable for use as a dwelling at the effective date of the transaction, readers should be aware that the legal threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That decision makes clear that poor condition, disrepair, or the need for works will not easily take a property outside the normal residential SDLT treatment. In those cases, both the merits of the claim and the processing time may be affected by the strength of the evidence.

Outcome

The practical takeaway is that an SDLT repayment claim often takes around 6 weeks, with a broader typical range of about 4 to 12 weeks. However, there is no guaranteed timescale, and claims involving technical points such as chattels can take longer if HMRC wants to review the evidence.

Practical Steps

If you are waiting for an SDLT repayment or considering making a claim, the sensible next steps are:

• check exactly what basis the claim has been made on;
• make sure the submission clearly identifies the legal argument;
• gather supporting evidence for any chattels values or other adjustments;
• keep copies of the SDLT return, amendment, and all supporting documents;
• allow a reasonable period for HMRC processing before chasing;
• be prepared for a longer wait if HMRC raises questions.

If the claim relates to chattels, particular care should be taken to distinguish genuine removable items from fixtures, and to ensure that any values used are realistic and defensible.

If the claim relates to property condition or alleged uninhabitability, it is important to assess the position against the current high threshold confirmed in Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Conclusion

There is no fixed HMRC turnaround for SDLT repayment claims, but many are dealt with in roughly 4 to 12 weeks, with around 6 weeks being a common expectation for a straightforward case. The stronger and clearer the evidence, the better the chance of a smoother and quicker outcome.
