Can you reclaim higher rates of LTT if you buy a new home before selling your old one?

Introduction

A common Land Transaction Tax question in Wales is whether a buyer can recover the higher residential rates after buying a new home while still owning a previous property. This often happens where the old home has been kept and let out, and the buyer later plans to sell it. Another frequent concern is whether a temporary period living with family or in other short-term accommodation affects the reclaim.

In general, a refund may be available where the old property was previously the buyer’s only or main residence, the new purchase is intended to be the new main residence, and the old main residence is sold within the permitted time limit. The fact that the buyer lived with parents or elsewhere in the meantime does not automatically prevent a reclaim.

The Question

A buyer owns one property in their personal name. They lived in that property as their home for a period, then moved out, let it to tenants, and temporarily lived with parents. They now want to buy a new home jointly with a partner who does not own any property. At the time of the new purchase, the buyer will still own the earlier dwelling.

The question is whether the higher residential rates of LTT will apply on the new purchase, and if so, whether those higher rates can later be reclaimed if the earlier property is sold within three years. A further question is whether the temporary period living with parents causes any problem.

Nick’s Explanation

Nick’s key point was that ownership matters first. If the earlier property is owned personally, it counts as an existing major interest in another dwelling. If it were instead owned by a company, that would usually not be treated as the individual’s personal dwelling interest for this purpose.

On the facts given, where the earlier property is in the buyer’s personal name, Nick explained that the higher rates would apply on the purchase of the new home because the buyer still owns another dwelling at that point.

He then explained the refund position in substance as follows: if the earlier property was the buyer’s main residence before the new purchase, and it is sold within three years after buying the new home, the higher rates can generally be reclaimed, provided the reclaim is made within 12 months of the sale.

Nick also confirmed that a temporary period living with parents between moving out of the former home and buying the new one does not, by itself, prevent the refund. The important point is that the old property must have been the buyer’s main residence before the purchase of the new home.

The Law

Land Transaction Tax in Wales is charged under the Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017. The higher residential rates apply where, at the effective date of the transaction, the buyer owns another dwelling and the new purchase is not excluded from the higher rates rules.

There is a special replacement of main residence rule. Broadly, where a buyer purchases a new main residence before disposing of their previous main residence, the higher rates may have to be paid up front. However, if the previous main residence is later sold within the allowed period, the buyer may reclaim the higher rates element.

For a successful reclaim, the earlier dwelling must have been the buyer’s only or main residence at some point during the relevant period before the new purchase, and the new dwelling must be intended as the replacement main residence. The old main residence must then be disposed of within three years of the purchase of the new dwelling. The reclaim must also be made within the statutory time limit, commonly within 12 months of the sale of the old residence.

Whether a property is a person’s only or main residence is a factual question. It depends on the quality of occupation rather than a simple label. Temporary accommodation elsewhere does not necessarily break the analysis if the statutory conditions for replacing a main residence are otherwise met.

Where readers are considering whether a dwelling was unsuitable for use as a residence, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That authority indicates that “not suitable for use” is not satisfied by ordinary disrepair, inconvenience, or the need for renovation unless the condition is genuinely serious.

Analysis

Step one is to identify the position on the purchase date of the new home. If the buyer still owns the earlier property in their personal name, they will usually be treated as owning an additional dwelling. That means the higher residential rates are likely to apply when the new property is bought.

Step two is to ask whether the new purchase is replacing a former main residence. On these facts, the earlier property was actually lived in as the buyer’s home before it was let out. That is important. A property can still qualify as the former main residence even if it has been rented out by the time the new purchase takes place, provided it was the buyer’s only or main residence during the relevant period.

Step three is to consider the gap period. The buyer moved out and lived with parents before buying the new home. That does not automatically stop the reclaim. The legislation does not require uninterrupted occupation of another owned home right up to the purchase date. What matters is that the old property was previously the buyer’s main residence and that the new property is bought as the replacement main residence.

Step four is to check the disposal deadline. If the old main residence is sold within three years after the purchase of the new home, the buyer can generally seek a refund of the higher rates paid on the new purchase.

Step five is to check the claim deadline. Even where the substantive conditions are met, the reclaim can be lost if it is not submitted in time. The usual deadline is within 12 months of the sale of the former main residence.

Step six is to note the joint purchase point. Buying with a partner who is a first-time buyer does not remove the higher rates if the other buyer already owns another dwelling and the transaction falls within the higher rates rules. For LTT purposes, the presence of one buyer with an additional dwelling can bring the whole transaction into the higher rates regime.

Finally, if there were any argument that the earlier property should somehow be ignored because it was uninhabitable, that would need careful scrutiny. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the bar for showing that a dwelling is not suitable for use as a residence is relatively high.

Outcome

On the scenario described, the practical answer is usually yes:

• the higher residential rates of LTT are likely to be payable when the new home is bought, because the buyer still owns the earlier property in their personal name;
• if that earlier property was the buyer’s former main residence, and it is sold within three years of the new purchase, the higher rates element can generally be reclaimed; and
• living with parents in the period between moving out of the old home and buying the new home does not, on its own, prevent the reclaim.

Practical Steps

To assess your position, work through the following points:

1. Confirm who owns the earlier property. If it is owned by you personally, it will usually count. If it is owned by a company, the analysis may be different.
2. Gather evidence that the earlier property was your only or main residence before it was let. Useful evidence may include council tax records, electoral roll entries, utility bills, mortgage correspondence, driving licence records, and HMRC records showing that address as your home.
3. Keep clear records of the date you complete the purchase of the new home and the date you complete the sale of the old home.
4. Check that the sale of the old home takes place within three years of the purchase of the new one.
5. Submit the reclaim within 12 months of selling the former main residence.
6. If there is any unusual feature, such as separation, trust ownership, mixed use, partial interests, inherited shares, or arguments about whether a dwelling was suitable for use, review the position carefully before filing.

Conclusion

If you buy a new home in Wales while still owning your former home, the higher rates of LTT will often apply at the outset. But where the old property was your previous main residence, you can usually reclaim those higher rates if you sell it within three years and make the reclaim on time. A temporary period living with parents does not usually change that result.
