Can you reclaim the higher SDLT rate after selling your previous main residence to a company?

Introduction

Many homeowners pay the higher rates of Stamp Duty Land Tax (SDLT) when they buy a new home before they have sold their old one. A common follow-up question is whether they can later reclaim that extra SDLT if the former home is disposed of within the permitted time limit.

This issue often becomes more complicated where the old home is not sold directly to an ordinary buyer, but is instead transferred to a company. It can also become messy if the refund application contains the wrong applicant details, the wrong address, or HMRC asks for a missing SDLT reference.

This article explains how the replacement of a main residence refund works, how the filing deadline is calculated, and what documents are usually needed to support the claim.

The Question

A married couple bought a new home as their intended main residence. At the time of that purchase, one spouse still owned their previous main residence, so the higher rates of SDLT were paid on the new purchase.

They later disposed of the former residence within three years, but the disposal was to a company rather than directly to an individual buyer. A refund claim was then submitted to HMRC close to the end of the time limit.

The practical questions were:

• Does a transfer of the former main residence to a company count as a disposal for refund purposes?
• Was the refund claim made in time?
• What happens if the claim form names the wrong person as applicant or refers to the wrong address?
• What evidence should be sent to HMRC if the original conveyancer has closed down and the SDLT5 certificate or UTRN is missing?

Nick’s Explanation

Nick’s view was that the refund should in principle be available because the former main residence had been disposed of within three years of buying the new home, and the claim had been submitted within the statutory window.

He identified two administrative issues that could confuse HMRC:

• the claim appeared to have been submitted by one spouse even though the lead purchaser and intended claimant was the other spouse; and
• the address shown in the submission did not clearly identify the property for which the refund was being claimed.

Nick’s approach was to write to HMRC to clarify who the lead purchaser was, confirm which dwelling the refund related to, and provide supporting documents showing both the purchase of the new main residence and the disposal of the former one.

He also added an important legal point on timing. In anonymised form, his reasoning was that the claim was still valid because the legislation allows amendment of the original SDLT return within 12 months beginning with the later of:

• the effective date of the disposal of the former residence, or
• the filing date for the return.

He then linked that to the statutory definition of “filing date”, which is not the day the return was actually filed, but the last day of the period within which it had to be delivered. Because the filing date fell 14 days after the disposal, that later date extended the final deadline for the refund claim.

The Law

The higher rates for additional dwellings are found in Schedule 4ZA to the Finance Act 2003.

Where a purchaser buys a dwelling and, at the end of the day of purchase, still owns another dwelling, the higher rates may apply. However, there is a refund mechanism where the new dwelling is bought as a replacement for the purchaser’s only or main residence and the old main residence is disposed of later.

The key provision is Finance Act 2003, Schedule 4ZA, paragraph 3(7), which deals with cases where the former only or main residence is disposed of after the purchase of the new dwelling.

The time limit for amending the return to claim the refund is set out in Finance Act 2003, Schedule 4ZA, paragraph 8(3):

“A land transaction return in respect of the transaction concerned may be amended, to take account of the application of paragraph 3(7), at any time within the period of 12 months beginning with—
(a) the effective date of the subsequent transaction, or
(b) if later, the filing date for the return.”

The meaning of “filing date” is given by Finance Act 2003, Schedule 10, paragraph 2(1):

“References in this Part of this Act to the filing date, in relation to a land transaction return, are to the last day of the period within which the return must be delivered.”

The period for delivery is provided by Finance Act 2003, section 76(1):

“The purchaser must deliver a land transaction return before the end of the period of 14 days after the effective date of the transaction.”

In practical terms, that means the refund deadline is often 12 months from the disposal of the old residence, but if the statutory filing date is later, the later date governs.

Analysis

There are four main points to consider.

First, was the new property bought as a replacement main residence?

On the facts described, yes. The couple bought the new property intending to live in it as their home. The fact that they did not move in immediately because they wanted to carry out works does not by itself prevent the replacement rules from applying. What matters is whether the new dwelling was genuinely intended to replace the old main residence.

Secondly, was the former main residence disposed of in time?

Yes, if the disposal took place within three years of the purchase of the new main residence. On the facts provided, the former residence was disposed of within that three-year period.

Thirdly, does a transfer to a company count as a disposal?

In general, yes. For SDLT refund purposes, the question is whether the purchaser has ceased to own the former main residence by way of a disposal recognised by the legislation. A transfer of the legal interest to a company can satisfy that requirement, provided it is a genuine disposal and not a case where the individual still retains ownership of the dwelling in the same capacity.

The later onward sale by the company is not the key event for the refund claim. The relevant disposal is the transfer that took the former residence out of the individual’s ownership.

Fourthly, was the refund claim made in time?

Using the dates described in the correspondence:

• the new main residence was bought on 22 February 2022;
• the former main residence was disposed of on 20 February 2024;
• the refund claim was submitted on 5 March 2025.

If one simply counted 12 months from 20 February 2024, the claim would appear late. But that is not the full legal test. Under Schedule 4ZA paragraph 8(3), the 12-month period runs from the later of the disposal date and the filing date for the return.

Because section 76(1) gives 14 days after the effective date for filing, the filing date for a disposal on 20 February 2024 was 5 March 2024. That was later than the effective date itself. The 12-month amendment window therefore ran until 5 March 2025.

A claim submitted on 5 March 2025 was therefore within time.

The remaining issues are procedural rather than substantive. If the wrong spouse is named as applicant, or a different address is shown, HMRC may pause the claim or ask questions. That does not necessarily defeat the claim. It usually means HMRC needs a clear explanation identifying:

• the lead purchaser of the new dwelling;
• the property to which the refund relates;
• the former main residence that was disposed of; and
• the dates that bring the claim within Schedule 4ZA paragraph 8(3).

Where the original conveyancer has closed down and the SDLT5 certificate or UTRN cannot easily be obtained, HMRC will often consider alternative supporting evidence. That may include:

• the TR1 transfer form;
• completion statements;
• the purchase contract and sale contract;
• Land Registry records;
• HMRC correspondence about the refund claim;
• evidence explaining why the UTRN is unavailable.

The key is to give HMRC enough material to match the claim to the correct land transaction and verify that the statutory conditions are met.

Outcome

On these facts, the practical conclusion is that the taxpayers appear to have a valid claim for repayment of the higher SDLT rates.

The main reasons are:

• the new property was bought as a replacement main residence;
• the former main residence was disposed of within three years;
• the disposal to a company can count as the relevant disposal; and
• the claim submitted on 5 March 2025 was within the statutory amendment window because the filing date rule extended the deadline.

Any mismatch in names or addresses should be corrected in correspondence with HMRC and supported by documentary evidence.

Practical Steps

If you are in a similar position, the sensible next steps are:

1. Identify the effective date of the purchase of the new dwelling.
2. Identify the effective date of the disposal of the former main residence.
3. Check whether the disposal took place within three years of the new purchase.
4. Calculate the refund deadline under Finance Act 2003, Schedule 4ZA, paragraph 8(3), using the later of:
   • the disposal date, and
   • the statutory filing date for that return.
5. Make sure HMRC has the correct claimant, usually the lead purchaser or an authorised representative.
6. Make sure the refund application clearly identifies the correct property.
7. Gather supporting documents, especially:
   • SDLT5 certificate if available;
   • TR1 forms;
   • contracts;
   • completion statements;
   • HMRC letters;
   • Land Registry evidence.
8. If a UTRN is missing because the conveyancer has ceased trading, explain that clearly and provide substitute evidence.
9. In any covering letter, set out the timeline in date order and cite the legislation directly so the HMRC caseworker can follow the point easily.

If your case instead turns on whether a dwelling was uninhabitable or not suitable for use as a dwelling, note that the legal threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. Ordinary disrepair, renovation needs, or a period of works will not necessarily be enough.

Conclusion

A homeowner who pays higher SDLT on a new main residence can often reclaim it after disposing of the old main residence, even where that disposal is to a company rather than to a private buyer. The crucial points are whether the old home was genuinely the former main residence, whether it was disposed of within three years, and whether the refund claim was made within the statutory amendment period. Where HMRC raises administrative queries, a clear timeline and the right documents usually make the difference.
