Can you reclaim SDLT if a guesthouse was wrongly treated as residential?

Introduction

People often search for this issue after buying a property that was operating as a guesthouse, hotel-style business or other commercial accommodation, only to find that Stamp Duty Land Tax (SDLT) may have been paid on the wrong basis. A common problem is that the original SDLT return treated the building as residential, when the buyer later believes it should have been treated as non-residential or mixed-use.

The two main questions are usually these: first, whether a trading guesthouse can fall outside the definition of a dwelling for SDLT purposes; and second, whether HMRC can still correct the position after the normal 12-month amendment window has passed. The answer depends on the facts, the statutory time limits, and the evidence showing how the property was actually being used at the effective date of the transaction.

The Question

A buyer purchased a property that had been run as a guesthouse business for many years. The buyer later argued that the SDLT return had been completed in error because the property was treated as residential, when it should instead have been treated as non-residential on the basis that it was a trading guesthouse at the time of purchase.

HMRC appeared to reject the claim by relying on the rule that amendments to a land transaction return normally must be made within 12 months of the filing date. The buyer wanted to know whether that was the end of the matter, or whether an overpayment claim could still be made within a longer statutory period where the original self-assessment was wrong.

Nick’s Explanation

Nick’s core point was that HMRC had focused on the 12-month amendment rule, but that is not the only relevant provision. He explained that where SDLT has been overpaid because of an error in the original return, the buyer may be able to rely on the separate overpayment relief provisions in Finance Act 2003, Schedule 10.

In anonymised form, his reasoning was:

• an ordinary amendment to an SDLT return is usually subject to a 12-month deadline;
• but a claim for repayment of overpaid tax under Schedule 10 paragraph 34 is subject to a four-year limit under paragraph 34B(1);
• if the original return was wrong because the property should have been treated as non-residential, the buyer may still be in time if the claim is made within four years of the effective date of the transaction;
• a guesthouse may fall within Finance Act 2003, section 116(3)(f), which excludes “a hotel or inn or similar establishment” from being treated as a dwelling.

Nick also highlighted the practical importance of evidence. The buyer would need to show that, at the relevant date, the property was genuinely operating as a guesthouse or similar commercial accommodation, rather than simply being capable of residential occupation.

The Law

The starting point is Finance Act 2003, which governs SDLT.

Finance Act 2003, Schedule 10, paragraph 6 deals with amendment of a land transaction return by the purchaser. In broad terms, paragraph 6(3) says that, except as otherwise provided, an amendment may not be made more than 12 months after the filing date.

However, Schedule 10 also contains a separate regime for overpayment relief. Paragraph 34 allows a claim for relief where tax has been overpaid, and paragraph 34B(1) provides:

“A claim under paragraph 34 may not be made more than 4 years after the effective date of the transaction.”

That distinction matters. A late claim is not necessarily barred just because the 12-month amendment window has expired. If the taxpayer is not simply seeking to amend in time, but is instead making a statutory claim for repayment of overpaid tax caused by an error, the four-year time limit may apply.

On classification, Finance Act 2003, section 116 defines “residential property” and “dwelling”. Section 116(3) provides that certain buildings are not used as a dwelling for these purposes. In particular, section 116(3)(f) states that “a hotel or inn or similar establishment” is not used as a dwelling.

That means a property can look domestic in physical form, yet still fall outside residential treatment if, at the effective date, its actual use was as a hotel, inn or similar establishment.

Where a taxpayer argues that a property was uninhabitable or not suitable for use as a dwelling, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That authority makes clear that disrepair arguments are not easy to establish. In a guesthouse case, the stronger point may often be the section 116 use analysis, rather than an argument that the building was physically unsuitable for use.

Analysis

The issue can be analysed in four steps.

First, identify what HMRC have actually refused. If HMRC have only said that the return cannot be amended because more than 12 months have passed, that does not fully answer whether an overpayment relief claim can still be made under Schedule 10 paragraph 34.

Second, decide whether the complaint is really about a late amendment or about an error in the original self-assessment. If the SDLT return wrongly classified the property as residential when, on the facts and law, it should have been non-residential, that is capable of being framed as an overpayment claim.

Third, examine the status of the property at the effective date of the transaction. The key question is not simply what the building looked like, but how it was being used. Evidence that may help includes:

• planning records showing guesthouse use or a later change of use;
• sale particulars describing the property as a guesthouse or trading accommodation business;
• licensing, business rates or council records;
• historic trading records, booking records or online listings;
• the contract, transfer and completion documents showing the nature of the asset sold.

Fourth, test whether the guesthouse was truly “similar” to a hotel or inn within section 116(3)(f). Nick’s view was that a trading guesthouse is generally commercial accommodation and therefore should not be treated as a dwelling. That can be a strong argument, but it remains fact-sensitive. HMRC may look at matters such as:

• whether paying guests were actually accommodated there;
• whether the property was held out to the public as guest accommodation;
• whether the layout and operation were consistent with a guesthouse business;
• whether any part was used as private living accommodation.

If the evidence shows that the property was operating as a guesthouse business at completion, there is a credible argument that it fell within section 116(3)(f) and was not residential property for SDLT purposes.

If part of the building was separately used as private residential accommodation, mixed-use treatment may also need to be considered. But where the whole property functioned as a trading guesthouse, the non-residential argument may be the cleaner route.

Outcome

A buyer in this situation should not assume that HMRC are right merely because 12 months have passed since filing. If the original SDLT return contained an error and the tax was overpaid, Finance Act 2003, Schedule 10, paragraph 34B(1) may allow a claim within four years of the effective date of the transaction.

Where the property was genuinely operating as a guesthouse at the time of purchase, there is a real basis for arguing that it was a “hotel or inn or similar establishment” within Finance Act 2003, section 116(3)(f), and so was not a dwelling for SDLT purposes.

The strength of the claim will depend heavily on documentary evidence of the property’s actual use at the relevant date.

Practical Steps

If you are assessing a similar case, take these steps:

1. Check the effective date of the transaction and calculate whether you are still within four years.
2. Obtain the SDLT return, SDLT5, contract for sale, TR1 and completion statement if available.
3. Gather evidence showing the property’s use at completion, such as planning records, council records, sales particulars, business rates evidence and guesthouse trading material.
4. Review whether the claim should be framed as overpayment relief under Finance Act 2003, Schedule 10 paragraph 34, rather than as a simple amendment under paragraph 6.
5. Set out clearly in writing why the original self-assessment was wrong and why section 116(3)(f) applies.
6. Do not rely on a disrepair or “not suitable for use” argument unless the facts are strong, because the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

A concise claim letter will usually need to explain:

• that the original SDLT treatment was erroneous;
• that the claim is made under Schedule 10 paragraph 34 within the time limit in paragraph 34B(1);
• that the property was, at the effective date, a trading guesthouse falling within section 116(3)(f);
• what documents are enclosed in support.

Conclusion

If a property was operating as a guesthouse when it was bought, it may have been wrongly treated as residential for SDLT. Even if the normal 12-month amendment period has expired, a repayment claim may still be possible within four years under Finance Act 2003, Schedule 10 paragraph 34B(1). The key is to present the case as an overpayment caused by an error and support it with clear evidence of commercial guesthouse use at the time of the transaction.
