Can you reclaim the higher rates of SDLT after selling your previous main residence?

Introduction

A common Stamp Duty Land Tax question is whether the 3% higher rates can be reclaimed after buying a new home and then selling the old one later. This issue often arises where a person bought a replacement main residence but still owned another dwelling on the purchase date, so the higher rates were paid first and a refund claim had to be made later.

The source material here concerns exactly that kind of situation: a homeowner wanted to know whether money might be due back in relation to SDLT paid when a home was bought and later sold, including a period when the property was held through a company. Nick’s reply focused on the urgency of making an electronic reclaim application within the time limit and gathering the paperwork needed for HMRC.

The Question

In general terms, the scenario was this:

A buyer wanted to establish whether they were entitled to a refund of the higher rates of SDLT paid on a dwelling that was intended to be their main home. The history involved a purchase and sale of a residential property, with ownership having at different times been in an individual’s name and later in a company connected with that individual. Because of tight filing deadlines, the immediate issue was whether a reclaim of the additional 3% SDLT should be submitted to HMRC straight away, with supporting documents to follow.

Nick’s Explanation

Nick’s central point was procedural but important: where there is a possible reclaim of the higher rates on a replacement of a main residence, the claim should be submitted quickly if the deadline is close.

In anonymised form, his advice was that, due to “very tight deadlines on case submission”, an electronic application should be made to reclaim the additional rates of stamp duty on the taxpayer’s primary dwelling. He also made clear that the supporting case would then be assembled and filed properly with HMRC, and that HMRC would require valid written authorisation before accepting an agent’s involvement.

That reflects good SDLT practice. If a buyer appears to satisfy the replacement of main residence rules, missing the reclaim deadline can be fatal even where the substantive tax position is otherwise favourable.

The Law

The higher rates of SDLT for additional dwellings are charged under Schedule 4ZA to the Finance Act 2003.

In broad terms, the higher rates can apply when, at the end of the day of purchase, the buyer owns more than one dwelling and is not treated as replacing their only or main residence on that date.

However, Schedule 4ZA also provides a refund mechanism where:

• the buyer purchases a new dwelling intended to be their only or main residence,
• the higher rates were paid because the buyer still owned their previous residence at the time of purchase, and
• the previous only or main residence is disposed of within the permitted period.

The permitted period has changed over time, but for many transactions the key practical question is whether the old main residence was sold within three years of the new purchase.

HMRC’s published guidance on higher rates for additional dwellings explains the reclaim process and time limits. A reclaim must normally be made by the later of:

• 12 months after the effective date of the sale of the previous main residence, and
• 12 months after the filing date for the SDLT return for the new purchase.

The claim is usually made through HMRC’s SDLT amendment or repayment process, depending on timing and the procedural route available.

Analysis

Whether a refund is due depends on several linked questions.

First, was the dwelling bought as a replacement for the buyer’s only or main residence? This is a factual question. HMRC looks at the reality of occupation and use, not just what the buyer says after the event.

Second, did the buyer still own another dwelling when the new one was purchased? If yes, the higher rates may have been correctly charged at the time of completion.

Third, was the previous only or main residence sold within the statutory period? If it was, that is the point at which a reclaim may become available.

Fourth, who bought and who sold? This matters greatly. For SDLT, an individual and a company are separate legal persons. If a property was held first by an individual and later by a company, that does not automatically mean the company’s ownership can be treated as the individual’s ownership, or vice versa. The reclaim rules must be applied to the actual purchaser and the actual disposer.

That means a careful review is needed of:

• the buyer named on the SDLT return for the new purchase,
• the owner of the previous residence before it was sold,
• whether the previous residence was genuinely the buyer’s only or main residence, and
• the dates of purchase, sale and filing.

If the same individual bought the new home, paid the higher rates because they still had an interest in their previous main residence, and then sold that previous main residence within the relevant period, a refund claim may well be available.

If, however, the old property was owned and sold by a company rather than by the individual buyer, the position becomes more difficult. A company’s dwelling is not normally treated as the individual’s previous main residence for the purpose of the individual’s reclaim. Equally, if the company was the buyer, the company cannot usually rely on the individual’s personal residence history in the same way.

So the mere fact that a person owned or controlled the company does not itself solve the SDLT issue. The legal identity of the purchaser and seller remains critical.

The source material also shows another practical point: HMRC may require proper agent authorisation before discussing or processing a reclaim through advisers. That is not just administration. If authority is not validly in place, a claim can be delayed at exactly the wrong moment.

Finally, some readers ask whether a property that was in very poor condition can be treated as not suitable for use as a dwelling, so that the higher rates do not apply in the first place. That is a separate argument from a replacement of main residence reclaim. In an uninhabitable or not suitable for use case, the condition threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property will not escape residential SDLT treatment merely because it needs repair or modernisation. Serious disrepair must be shown.

Outcome

The practical answer is this:

A refund of the 3% higher rates may be due if the buyer paid the surcharge on buying a new main home and later sold their previous main residence within the statutory period. But the claim depends on the legal identity of the buyer and seller, the residence facts, and the filing deadline.

Where ownership moved between an individual and a company, the position cannot be assumed. The transaction documents and SDLT returns need to be checked carefully before concluding that a reclaim is available.

Practical Steps

If you are assessing a similar SDLT reclaim, gather and check the following:

• the completion statement and SDLT return for the new purchase,
• the transfer deed and sale completion statement for the previous residence,
• the exact dates of purchase, sale and SDLT filing,
• evidence showing which property was your only or main residence,
• Land Registry entries showing who owned each property, and
• any evidence relevant to whether the buyer was an individual or a company.

Then ask these questions in order:

1. Who was the buyer on the new purchase?
2. Was the higher rates SDLT paid?
3. What was that buyer’s previous only or main residence?
4. Was that previous residence sold within the permitted period?
5. Is the reclaim still within HMRC’s time limit?

If the deadline is close, submit the reclaim promptly with the best available information and then complete any supporting material required by HMRC as soon as possible.

Conclusion

You can sometimes reclaim the higher rates of SDLT after selling your old home, but only if the statutory replacement of main residence conditions are met and the claim is made on time. Where a company is involved in the ownership history, the analysis becomes much more technical because the individual and the company are separate legal persons for SDLT purposes.
