Can you reclaim the 3% SDLT surcharge if you sell the new property instead of your old main home?

Introduction

A common SDLT question is whether the 3% higher rates can be reclaimed where a buyer intended to replace their main residence, but life events meant the plan changed. This often arises after bereavement, probate delays, or a failed redevelopment project.

The key point is that the refund rules for replacing a main residence are quite specific. In most cases, the refund is available only if the buyer later disposes of the old main residence. If instead the buyer keeps the old home and sells the newly bought property, the normal refund route usually does not apply.

The Question

A married couple bought a second residential property and paid the higher rates of SDLT because they still owned their existing home. The intention was to develop or adapt the newly bought property and then move into it as their main residence, after which the old home would be sold and the 3% surcharge reclaimed.

Before that could happen, one spouse died. Probate and the surrounding administration delayed matters. The project did not go ahead, the buyer remained living in the original main residence, and the newly bought property was eventually sold instead. The question is whether the 3% SDLT surcharge can still be reclaimed because the original plan was frustrated by bereavement and probate.

Nick’s Explanation

Nick’s reasoning focused on an important distinction. He noted that if the buyer had sold the original main residence within the relevant time limit, a refund claim would normally have been possible. But where the buyer kept the original main residence and instead sold the later-acquired property, the position became much harder.

In anonymised form, his view was essentially this:

If the old main home is sold within the permitted period after buying the new one, the higher rates can usually be reclaimed. But if the buyer keeps the old main home and sells the newer property instead, the refund route is much more difficult and, technically, the surcharge is not normally repayable because the old main residence has not been sold.

Nick also observed that HMRC may sometimes accept that events outside the buyer’s control can affect the timing of a sale. That can matter where the correct property is eventually sold, but the sale happens late. However, that is different from a case where the buyer never sells the former main residence at all.

The Law

The higher rates of SDLT on additional dwellings are set out in Schedule 4ZA to the Finance Act 2003.

Broadly, the 3% surcharge applies where, at the end of the day of the purchase, the buyer owns more than one dwelling and is not replacing their only or main residence on that day.

A refund may later be available where:

• the buyer paid the higher rates on the purchase of a new dwelling, and
• the buyer then disposes of a previous dwelling that was their only or main residence, and
• the disposal falls within the statutory time limit, subject in some cases to HMRC accepting that exceptional circumstances beyond the buyer’s control prevented an earlier sale.

The legislation is aimed at a specific factual pattern: buying a new home before selling the old one, then later selling the old main residence. It is not a general relief for changed intentions or abandoned plans.

It is also worth noting that if anyone considers arguing that the purchased property was not suitable for use as a dwelling, the legal threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property does not fall outside the dwelling rules merely because works were planned, the property needed adaptation, or it was inconvenient to occupy. The condition must be serious enough to meet that now stricter standard.

Analysis

The analysis turns on the structure of the replacement of main residence rules.

Step 1: Why was the 3% surcharge paid in the first place?

It was paid because, when the later property was bought, the buyers still owned their existing main residence. That meant they owned more than one dwelling at completion, so the higher rates applied unless the old main residence had already been sold.

Step 2: What event normally triggers a refund?

The usual trigger is the later sale of the former main residence. That sale shows that the buyer has, in substance, replaced one main home with another.

Step 3: What happened here?

The former main residence was not sold. Instead, the later-acquired property was sold, and the buyer continued to live in the original home.

Step 4: Why does that matter?

Because the statutory refund mechanism is tied to disposing of the previous main residence, not to disposing of the new property. The fact that the buyer originally intended to move does not by itself create a refund entitlement if the transaction sequence ultimately never became a replacement of main residence.

Step 5: Do bereavement and probate change the answer?

They may help on timing where the correct disposal eventually takes place. For example, if a buyer does later sell the previous main residence but misses the normal deadline because exceptional circumstances outside their control delayed the sale, HMRC may in some cases accept that. But those circumstances do not usually rewrite the basic condition that the previous main residence must actually be sold.

Step 6: Does it help that the later property was bought with the intention of becoming the new home?

Intention matters in some SDLT contexts, but for this refund route the legislation is driven mainly by what actually happened. Here, the buyer remained in the original home and sold the new property instead. On those facts, the normal refund conditions do not appear to be met.

Step 7: What about the buyer purchasing another property later and then selling the current main residence?

That later transaction would need to be analysed on its own facts. It may create a separate higher-rates position and potentially a separate refund route if the buyer then replaces their main residence in the statutory way. But it does not normally revive a refund claim for the earlier purchase that ended with the new property being sold off.

Outcome

On these facts, the practical conclusion is that the 3% SDLT surcharge paid on the earlier purchase is unlikely to be reclaimable. The main reason is simple: the buyer did not sell the previous main residence. Instead, the buyer kept that home and sold the later-acquired property.

Bereavement and probate are highly relevant and sympathetic facts, but they do not usually overcome the core statutory requirement for this particular refund.

Practical Steps

If you are assessing a similar case, work through the following points carefully:

• Identify which property was your only or main residence before the later purchase.
• Check which property was actually sold afterwards: the old main home or the newly bought property.
• Compare the dates of purchase and sale against the replacement of main residence rules in Schedule 4ZA Finance Act 2003.
• Gather evidence showing where you actually lived, such as council tax records, electoral roll details, insurance, utility bills, and correspondence.
• If the old main residence was sold late because of events outside your control, collect evidence of those events, such as probate records, estate administration papers, or documents showing legal barriers to sale.
• If considering any argument that a property was not suitable for use as a dwelling, review the condition evidence very carefully in light of Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, because the threshold is now relatively high.
• If there is a later purchase and later sale of the current main residence, analyse that as a fresh transaction rather than assuming it fixes the earlier one.

Conclusion

If you buy a second property, pay the 3% SDLT surcharge, and then keep your original main home while selling the newer property instead, the surcharge is usually not refundable. The refund rules are designed for cases where the old main residence is later sold. Delays caused by bereavement or probate may help with timing in the right case, but they do not usually create a refund where the old main home was never disposed of.
