Can you still reclaim SDLT on an uninhabitable property bought in 2019?

Introduction

Many buyers ask whether they can reclaim Stamp Duty Land Tax (SDLT) if a property was in very poor condition when they bought it. A common example is a house needing major renovation, structural work or a full internal refit. Another common question is whether there is a time limit for making that claim.

This matters because even if a buyer believes the property was not suitable for use as a dwelling, a refund claim will usually fail if it is made too late. It is also important to understand that the legal test for an “uninhabitable” property is now relatively strict following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

The Question

A buyer purchased a residential property in 2019. At the time of purchase, the property needed extensive renovation works and the buyer wondered whether SDLT could now be reclaimed on the basis that the property was not suitable for use as a dwelling. The buyer also asked about a future purchase involving a property said to be uninhabitable.

Nick’s Explanation

Nick’s key point was that, in England, a claim based on an error in the original SDLT self-assessment generally has to be made within 4 years of the effective date of the transaction. In anonymised form, his explanation was:

“You can only claim if there has been an error in the stamp duty self-assessment within 4 years from the date of purchase. Since the property was bought in 2019, the claim is now out of time.”

He also noted that some people confuse the position in England with Scotland, where different land transaction tax rules and time limits may apply.

The Law

SDLT is charged under the Finance Act 2003. Whether a property is treated as “residential property” depends on the statutory definition in section 116 Finance Act 2003. Broadly, property is residential if it consists of or includes a building that is used or suitable for use as a dwelling, or is in the process of being constructed or adapted for such use.

Where a taxpayer says too much SDLT was paid because the property should not have been treated as residential, the usual route is to amend the return if still within the amendment window, or otherwise to make an overpayment relief claim if the statutory conditions are met.

For SDLT, the key time limit for correcting an error in the self-assessment is commonly 4 years from the effective date of the transaction. In practice, that means a buyer who completed a purchase in 2019 will usually be out of time by 2025.

On the substantive issue of whether a property was suitable for use as a dwelling, the courts have repeatedly made clear that the test is applied at the effective date of the transaction. The question is not whether the buyer intended to renovate, modernise or improve the property. The question is whether, at completion, the property was objectively suitable for use as a dwelling.

The threshold in “not suitable for use” cases is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. Serious disrepair, outdated condition, missing fittings, or a need for major works will not automatically mean the property falls outside the residential property definition.

Analysis

The position can be analysed in two steps.

First, consider the time limit. If the property was bought in 2019 and the buyer is only now looking at a reclaim in 2025, the normal 4-year limit has passed. That is usually enough to end the matter, regardless of the property condition. Even a strong technical argument on uninhabitability will not normally revive a claim that is out of time.

Second, even if the claim had been in time, the buyer would still need to show that the property was not suitable for use as a dwelling at the date of completion. That is a demanding test. A property may need a full renovation, rewiring, replumbing, replacement kitchen or bathroom, damp treatment, or an extension, and still remain “suitable for use as a dwelling” for SDLT purposes.

The courts distinguish between:

• a property that is run down, dated or in poor repair, and
• a property that is truly incapable of functioning as a dwelling at the effective date.

After Mudan, the bar is relatively high. Buyers should not assume that a derelict appearance, substantial cost of works, or mortgage retention automatically proves non-residential treatment. The legal question is narrower and more exacting.

So in a 2019 purchase case, there are really two obstacles:

• the claim is likely out of time; and
• the underlying “unsuitable for use as a dwelling” argument may be harder to establish than many buyers expect.

For a future purchase, timing becomes critical. If a buyer thinks a property may not be suitable for use as a dwelling, that issue should be reviewed immediately after completion, and ideally before the SDLT return is finalised, because evidence from the transaction date is essential.

Outcome

If a property was bought in 2019 and the buyer is only now considering an SDLT reclaim on the basis that it was uninhabitable, the practical answer is usually no. The normal 4-year time limit has expired, so the claim is out of time.

For any new purchase, a buyer should not assume that “needs full renovation” means “not residential” for SDLT. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the condition threshold is relatively high.

Practical Steps

If you are assessing your own position, the sensible steps are:

1. Confirm the effective date of the transaction, usually the completion date.
2. Check whether you are still within the relevant SDLT time limit.
3. Obtain the SDLT return, completion statement, contract papers and any valuation or survey material from the time of purchase.
4. Focus on the actual condition at completion, not works carried out later.
5. Gather objective evidence such as survey reports, photographs, builder reports, utility status and any material showing whether the property could function as a dwelling on that date.
6. Assess the case against the current authorities, including the stricter approach confirmed in Mudan.
7. If the purchase is recent, review the SDLT position promptly rather than waiting, because delay can remove any possible remedy.

Conclusion

A buyer who purchased in 2019 will usually be too late to reclaim SDLT on the basis that the property was uninhabitable. Even if the timing problem did not exist, the legal test is now demanding, and a property needing major renovation will not automatically fall outside the residential SDLT rules.
