Can you reclaim the 3% SDLT surcharge if you rent your main home but own other properties?

Introduction

This is a common stamp duty question for people who already own one or more residential properties but do not currently own the home they live in. The issue usually arises where someone once lived in a property they owned, later let it out, and now rents their day-to-day home while planning to buy another property.

The key question is whether the higher rates of Stamp Duty Land Tax (SDLT) apply on the new purchase, and if so, whether the extra 3% can later be reclaimed. The answer depends on whether the purchase is a replacement of a main residence, or whether the property being bought falls outside the residential SDLT rules because it is not suitable for use as a dwelling on the effective date of the transaction.

The Question

A buyer owns residential property that is now let to tenants, but does not own the home they currently live in because they rent that home instead. They want to buy another property to live in and want to know:

• whether the higher rates of SDLT will apply because they already own other dwellings, and
• whether they can later reclaim the 3% surcharge by selling the former home they once lived in, or by buying a property in very poor condition.

Nick’s Explanation

Nick’s explanation was that this is different from the more familiar “sell old home within three years” scenario.

In anonymised form, the key point was:

“If your current main residence is rented rather than owned, the property you used to live in but now let out is not treated as the main residence you are replacing when you buy a new home. In that situation, selling that older property later would not produce the usual higher rates refund.”

He also explained that, in principle, if the newly purchased property is not suitable for use as a dwelling at the effective date of purchase, it may be treated as non-residential or mixed for SDLT purposes, which means the higher residential rates may not apply in the first place or may be capable of correction by amendment or reclaim if SDLT was initially paid on a residential basis.

However, any argument that a property is not suitable for use as a dwelling must now be approached with caution. The condition threshold is relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

The Law

SDLT on land transactions in England is charged under the Finance Act 2003.

The higher rates for additional dwellings are imposed by Schedule 4ZA to the Finance Act 2003. Broadly, the surcharge applies where, at the end of the day of the transaction, the buyer owns more than one dwelling and is not replacing their only or main residence.

The replacement of main residence rules are important. In general terms, a buyer may avoid the higher rates, or recover them later, if:

• they buy a new dwelling intended to be their only or main residence, and
• they dispose of a previous only or main residence within the period allowed by the legislation.

HMRC’s guidance on what counts as a main residence appears in the SDLT manual, including SDLTM09812. Whether a property is a person’s main residence is a factual question. It is not enough that the buyer owned it in the past or once lived there. What matters is whether it was their only or main residence in the relevant sense for the replacement rules.

A separate issue is whether the property being purchased is a “dwelling” at all for SDLT purposes. If, on the effective date of the transaction, the building is not suitable for use as a dwelling, it may fall outside the residential rates. That can affect both the ordinary residential rates and the higher rates surcharge.

The modern case law shows that “not suitable for use as a dwelling” is interpreted strictly. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the threshold is relatively high. Serious disrepair, dated condition, or the need for renovation will not automatically mean a property is non-residential. The condition must be such that the property is genuinely unsuitable for use as a dwelling at the effective date.

Analysis

Step one is to identify whether the buyer will own more than one dwelling at the end of the purchase day. If they already own one or more residential properties and buy another dwelling, the higher rates are likely to be in point.

Step two is to ask whether the new purchase is a replacement of the buyer’s only or main residence. This is where many buyers assume that a property they used to live in can still perform that role. Usually, it cannot if they no longer live there and instead rent another home which is their actual main residence.

If the buyer’s present main residence is a rented property, then the property they formerly occupied but now let out is generally not the residence being replaced. That matters because the refund mechanism for higher rates is tied to disposing of the previous only or main residence. Selling a buy-to-let or former home that is no longer the buyer’s main residence will usually not satisfy that test.

So in this type of case, the normal “pay the surcharge now and reclaim it when I sell the old place within three years” route is usually not available.

Step three is to consider the nature of the property being bought. If it is truly not suitable for use as a dwelling on completion, the transaction may not be taxed as the purchase of a residential dwelling. That could mean the higher residential rates do not apply.

But this route is much narrower than many buyers expect. A property does not stop being a dwelling merely because it is old, unattractive, missing some modern fittings, or needs substantial work. The courts now require a high level of uninhabitability before the property falls outside the dwelling definition. Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799 makes that clear.

Examples that may be relevant in these cases include severe structural failure, absence of basic facilities combined with wider defects, or other conditions showing the property cannot realistically be used as a dwelling at the effective date. Each case turns on its own facts, and evidence is critical.

Step four is procedural. If there is any doubt, many buyers choose to file and pay SDLT on the safer basis first, and then consider whether an amendment or reclaim is justified once the evidence has been reviewed carefully. That approach reduces the risk of underpayment penalties if HMRC later disagrees with the treatment adopted on filing.

Outcome

In this scenario, the practical answer is usually as follows:

• the higher rates of SDLT are likely to apply on the purchase of the new property because the buyer already owns other dwellings and is not replacing an owned main residence;
• selling the former home that is now let out will usually not trigger a refund of the 3% surcharge, because it is not the buyer’s current or recently replaced only or main residence for these purposes; and
• the only possible route away from the higher residential rates may be if the property being bought was not suitable for use as a dwelling at the effective date, but the threshold for that argument is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Practical Steps

If you are assessing a purchase in similar circumstances, the sensible steps are:

1. List every property interest you will own at the end of the transaction day.
2. Identify which property is genuinely your current only or main residence as a matter of fact.
3. Check whether you are actually replacing an owned main residence, rather than simply buying a home while continuing to own let properties.
4. If you think the new property is not suitable for use as a dwelling, gather strong contemporaneous evidence from the completion date, such as survey reports, photographs, contractor evidence, mortgage valuation material, and details of any missing or failed essential elements.
5. Test that evidence against the stricter approach now confirmed by Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.
6. Consider whether the SDLT return should be filed on a conservative basis first, with any amendment or reclaim made only after the legal position and evidence have been reviewed carefully.
7. Keep the filing deadline and any amendment or repayment time limits under review.

Conclusion

If you rent the home you actually live in, but own other residential properties, buying another home will usually attract the higher SDLT rates. In most cases, you cannot reclaim the surcharge simply by later selling a property you once lived in but now let out. A possible alternative argument is that the new property was not suitable for use as a dwelling, but that is now a demanding test and must be supported by strong evidence.
