Can you claim back Stamp Duty Land Tax on more than one property?

Introduction

People often ask whether they can reclaim Stamp Duty Land Tax (SDLT) after buying property, especially where they own several properties or are in the process of buying more. The answer depends entirely on why too much SDLT may have been paid. There is no general right to a refund simply because a person owns multiple properties. A repayment is only available if the original SDLT treatment was wrong, or if a later event creates a statutory right to reclaim part of the tax.

Common examples include overpayment of the higher rates for additional dwellings, incorrect treatment of mixed-use property, failure to claim a relief that was available at the time, or an error in the purchase return. Whether a refund is possible must be checked property by property.

The Question

A property owner says they have already bought two properties which they believe may qualify for an SDLT refund, and they are also buying two more. They want to know whether they can claim money back and what should be reviewed before completing further purchases.

Nick’s Explanation

Nick’s response, in substance, was that the first step is to review each property transaction individually to see whether there is a valid basis for reclaiming SDLT. A refund claim depends on the facts of each purchase, the SDLT return originally filed, and whether any relief or exemption was missed or wrongly denied.

In practical terms, his explanation points to two separate issues:

• whether the earlier purchases were overtaxed and can now be corrected; and
• how the upcoming purchases should be structured and reported so that the correct SDLT is paid from the outset.

That is the right approach. SDLT is highly fact-sensitive. A person with several properties may have different outcomes across different transactions.

The Law

SDLT is charged under the Finance Act 2003. The amount payable depends on the nature of the property, the effective date of the transaction, the consideration given, and whether any reliefs or higher rates apply.

The main provisions commonly relevant to refund questions include:

• Finance Act 2003, Part 4, which sets out the SDLT charge.
• Schedule 4ZA to the Finance Act 2003, which contains the higher rates for additional dwellings.
• The rules allowing repayment of the additional dwelling supplement where a previous main residence is disposed of within the permitted period.
• The amendment and correction provisions for SDLT returns, including claims for repayment where tax was overpaid.
• Reliefs and special rules, such as multiple dwellings relief for transactions completed before its withdrawal for most purchases, mixed-use treatment, and various targeted reliefs where the statutory conditions are met.

Where a buyer argues that a dwelling was not suitable for use as a dwelling at the effective date, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. Serious disrepair alone will not automatically take a property outside the dwelling rules. The condition must be sufficiently severe in legal terms.

Analysis

To work out whether SDLT can be reclaimed, each transaction should be tested in stages.

First, identify what was bought. Was it:

• a single dwelling;
• more than one dwelling;
• mixed-use property;
• non-residential property; or
• a property that was claimed not to be suitable for use as a dwelling?

That classification matters because SDLT rates and reliefs differ significantly.

Second, check whether the higher rates for additional dwellings were applied. If the buyer already owned another dwelling at the end of the day of purchase, the higher rates may have been due. However, if the purchase replaced the buyer’s only or main residence, or if the previous main residence was sold later within the statutory period, a refund may be available.

Third, check whether the original return missed a relief. In older transactions this may include multiple dwellings relief, if it was still available at the time and the facts supported it. In other cases, the issue may be that the property should have been treated as mixed-use rather than wholly residential. That can reduce the SDLT significantly, but only where the legal and factual position genuinely supports mixed-use treatment.

Fourth, review whether the buyer relied on the property being uninhabitable or unsuitable for use as a dwelling. This argument has become more difficult. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the courts have confirmed that the threshold is relatively high. Ordinary renovation needs, outdated condition, damp, defective kitchens or bathrooms, or similar problems may not be enough. The question is whether, viewed realistically and legally at the effective date, the property crossed the line from poor condition into not being suitable for use as a dwelling.

Fifth, check time limits and procedure. SDLT repayment claims are not open-ended. The route depends on the nature of the alleged overpayment. Some claims involve amending the return, while others require a repayment claim or overpayment relief argument. The relevant documents usually include:

• the SDLT return and submission receipt;
• the completion statement;
• the transfer deed and contract;
• title documents and plans;
• valuation evidence where relevant;
• photographs, surveys, and invoices where condition is in issue; and
• evidence of residence history if a main residence replacement refund is sought.

Finally, for the properties still being bought, the best course is to assess SDLT before exchange or completion. It is far easier to file correctly at the start than to try to recover tax later.

Outcome

A person who owns two properties and is buying two more may be able to reclaim SDLT, but only if there is a specific legal reason why too much tax was paid on one or more earlier purchases. There is no automatic refund because several properties are involved.

The likely practical answer is:

• review the two completed purchases separately to see whether there was an overpayment; and
• review the two pending purchases in advance so the correct SDLT treatment is used from the outset.

Practical Steps

If you want to assess whether an SDLT refund is possible, gather the following for each property:

• purchase price and completion date;
• whether the property was residential, mixed-use, or potentially non-residential;
• whether any other dwellings were owned at completion;
• whether the purchase replaced a main residence;
• the SDLT return and amount paid;
• any survey or evidence of condition at the time of purchase;
• details of any land, commercial element, annex, or separate dwelling; and
• for future purchases, the intended ownership structure and use of the property.

Then ask these questions for each transaction:

1. Was the property correctly classified for SDLT?
2. Were the higher rates correctly applied?
3. Was any available relief missed?
4. Is there a valid argument that the property was not suitable for use as a dwelling, bearing in mind the high threshold after Mudan?
5. Is the claim still within the relevant time limit?

Conclusion

You can only claim back SDLT where there is a proper legal basis for saying too much was paid. If you have already bought properties and are buying more, the sensible approach is to review each completed transaction for overpayment and check the SDLT position on the upcoming purchases before completion. In condition cases, remember that the bar for showing a property was not suitable for use as a dwelling is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.
