If you have already paid stamp duty on a UK property and your situation has since changed, you may be entitled to a stamp duty refund from HMRC. This applies if you have sold your previous home, your property turned out to be uninhabitable, or you were later told you overpaid.
This guide explains who qualifies for SDLT refund claim, what the deadlines are for the claim, and exactly how to apply.
Who Is Eligible for a Stamp Duty Refund?
You may be eligible for a Stamp Duty Land Tax (SDLT) refund if you have:
- Sold your previous main residence after paying the 5% surcharge
- Purchased a property that was uninhabitable or derelict at the time of buying
- Paid the 2% non-resident surcharge but have since met the 183-day UK residency test
- Transferred property within a group of companies and SDLT was paid
- Overpaid due to a solicitor or calculation error
This guide covers SDLT, which applies to property purchases in England and Northern Ireland. If your property is in Scotland or Wales, the equivalent taxes are Land and Buildings Transaction Tax (LBTT) and Land Transaction Tax (LTT) respectively. Contact Revenue Scotland or the Welsh Revenue Authority for guidance specific to your situation.
Things to keep in mind while considering eligibility criteria for SDLT.
- Availability of reliefs and exemptions: Find the right exemption or relief and then apply it correctly to your property purchase.
- Time limit: Check the deadline that applies to your specific refund type — these vary and are set out in the table below.
- Necessary documents: Make sure you've got all the paperwork to back up your claim.

Stamp Duty Refund on Second Home (Replacement of the Only or Main Residence)
Example 2 :
Nick bought his second residential property on 15 May 2025 for £275,000. Because he had not yet sold his previous home, he paid SDLT at the higher rates including the 5% surcharge, resulting in a total tax bill of £17,500. The surcharge element, the additional 5% applied across the full purchase price amounted to £13,750.
Later, on 30 August 2025, Nick sold his previous main residence. As a result of this sale, he became eligible to claim a refund of £13,750 for the additional SDLT surcharge he had paid on the new property.
In exceptional circumstances: If you bought a new home and couldn't sell your old home within 3 years due to reasons beyond your control (such as government restrictions or other unexpected events), you may still claim a refund. HMRC treats exceptional circumstances narrowly, so it must be shown that your sale was genuinely impacted by factors outside your control. Some reasons may include:
- The impact of COVID-19 or other government imposed restrictions preventing the sale.
- An action taken by a public authority preventing the sale
Personal financial difficulty or an inability to find a buyer does not qualify.

Stamp Duty Refund for Uninhabitable Property
Uninhabitable properties also known as derelict properties, plagued by unhealthy conditions or structural damage, pose unique challenges for property investors. However, they also offer opportunities for savvy investors looking to renovate and profit from their investments.
SDLT refunds may be applicable when acquiring a property initially deemed uninhabitable.
A landmark legal ruling in the case of P N Bewley Ltd v HMRC [2019] UKFTT 65 (TC) has clarified that properties not fit for habitation at the time of purchase do not fall under the 'dwelling' definition, thus non-residential rates apply to the property.
Further, non-residential rates are quite lower than the residential rates thereby resulting in substantial SDLT savings.
Example 3 :
Harry purchased the second property for £600,000 which is not suitable for a dwelling.
Due to his lack of awareness regarding SDLT rates, Harry mistakenly paid SDLT at the residential rates.
SDLT at Residential Rates | SDLT at Non-residential Rates |
|---|---|
5% 0n the first £125,000 = £6250 | 0% On the first £150,000 = 0 |
7% 0n the next £125,000 = £8750 | 2% on the next £100,000 = £2,000 |
10% on the remaining £350000 =35000 | 5% on the remaining £350,000 = £17,500 |
Total SDLT = £50,000 | Total SDLT = £19,500 |
Upon claiming derelict relief for uninhabitable property, his liability is reduced to £19,500, resulting in eligibility to claim a refund of £30,500.
SDLT Refund for Non-UK Residents
Non-UK residents are subject to a 2% additional surcharge in all reliefs and exemptions.
Did you know that non-UK residents who have lived in the UK for at least 183 days within a consecutive 365-day period may be eligible for a refund on the 2% extra surcharge they paid?
In the realm of property transactions, non-UK residents may seek reimbursement of the surcharge paid, provided they have resided in the UK for a cumulative period of 183 days within a consecutive 365-day timeframe.
- Starting up to 364 days before the effective date of the transaction.
- Ending up to 365 days after the effective date of the transaction.
Example 4 :
Here's a comparison of Stamp Duty Land Tax (SDLT) for resident and non-resident first-time buyers when purchasing a property valued at £600,000.
For Residents | For Non-Residents |
|---|---|
0% on the first £425,000 = 0 | 2% on the first £425,000 = £8,500 |
5% on the remaining £175,000 = £8,750 | 7% on the remaining £175,000 = £12,250 |
Total SDLT = £8,750 | Total SDLT = £20,750 |
Meeting the requirement of being present for 183 days within a 365-day timeframe in the UK, either 364 days before or 365 days following the transaction's effective date, will make you eligible to claim a refund of £12,000.
Usually, the effective date is the completion date of the transaction.
You must apply for repayment within two years of the transaction's effective date.
Stamp Duty Refund on properties with an Annexe
Have you ever felt like you've paid too much in stamp duty? If your property includes an annexe, granny flat, or a similar smaller structure suitable for use, you might have overpaid without even realising it.
But here's the good news: thanks to a rule change in 2018, properties with self-contained annexes are now classified as single dwellings. You could be entitled to a significant refund if the main building makes up at least two-thirds of the property's total value.
If your property includes an annexe and the main building accounts for at least two-thirds of the total value, you may have overpaid SDLT at the time of purchase. Our SDLT specialists can assess whether you qualify for a refund under the single-dwelling classification rule.
Stamp Duty Refund through Group Relief
Discover the potential for reclaiming Stamp Duty Land Tax when transferring land and buildings within a group of companies. This relief allow groups to move property for commercial reasons without considering Stamp Duty Land Tax implications.
To qualify as members of the same group of companies, one company must own at least 75% of the share capital of the other company, or a third company should own at least 75% of the share capital of both the buyer and the seller.If you've recently transferred land and buildings within a group of companies, there's a chance you've paid stamp duty. But fear not! You can seek a refund and possibly recover those overpaid amounts.
Stamp Duty Refund on Mixed-Use Property
If you purchased a property that contains both residential and non-residential elements, you may have overpaid SDLT by having it taxed at residential rates when the lower non-residential rates should have applied.
HMRC classifies a property as mixed-use when it contains a genuine, materially independent non-residential element alongside the residential part. Where a property qualifies as mixed-use, the non-residential rates of SDLT apply to the entire purchase price not just the commercial portion. This can result in a significantly lower SDLT liability on mixed-used property compared to the standard residential rates, particularly on higher-value properties.
When a property is purchased with a commercial shop on the ground floor with residential flats on the floors above.
The purchase price is £1,165,000 which is split £250,000 for the shop and £915,000 for three self-contained flats.
Under the non-residential rates, the Stamp Duty Land Tax (SDLT) liability amounts to £47,750.
0% on the first £150,000 = 0
2% on the next £100,000 = £2,000
5% on the remaining £915,000 = £45,750
Total SDLT = £47,750
If SDLT was paid at the full residential rates at the time of purchase, the difference between what was paid and the correct non-residential liability may be reclaimable.
Multiple Dwellings Relief (MDR), which previously provided an additional route to reduce SDLT on mixed-use transactions involving more than one dwelling, was abolished on 1 June 2024. It can no longer be claimed on transactions completed after that date. If your transaction completed before 1 June 2024 and MDR was not claimed at the time, speak to an SDLT specialist to confirm whether your amendment window remains open.

How Long Does a Stamp Duty Refund take?

Conclusion
Stamp duty refunds are a legitimate and often significant financial recovery but the process requires accurate eligibility assessment, the right documentation, and attention to deadlines.
A word of caution: if you have been contacted out of the blue by a no-win no-fee firm promising a stamp duty refund, verify their credentials before proceeding. HMRC has publicly warned homeowners about speculative claims submitted by such firms. Where a claim is found to be invalid, HMRC will require full repayment plus interest and penalties and that liability rests with you, not the firm that submitted the claim.
Whether you're seeking reimbursement for a second home, uninhabitable property, or mixed-use investment, exploring your options, and staying informed is key. Remember, accuracy and completeness are paramount to avoid rejections and delays.

Frequently Asked Questions
Yes. If your solicitor or conveyancer miscalculated your SDLT liability or failed to apply an available relief at the time of purchase, you may be able to amend your SDLT return and reclaim the difference. The standard amendment window is 12 months from the filing date of your original SDLT return. After this period, overpayment relief may still be available for up to 4 years from the effective date of the transaction, though the conditions are more restrictive.
It depends on the circumstances of all buyers in the transaction. If one buyer already owns a property, the higher rates for additional dwellings may apply to the entire purchase. However, if the purchase qualifies as a replacement of a main residence and the previous home is sold within 36 months, a refund of the surcharge may still be available. Where joint ownership involves a spouse or civil partner who owns other property, the rules become more complex and specialist advice is recommended before submitting a claim.
Missing your deadline generally removes your right to claim, even if your circumstances would otherwise qualify. HMRC does not have discretion to accept late claims outside of the specific exceptional circumstances provisions and those apply only to the main residence replacement surcharge refund, not to all refund types. If you are approaching a deadline and are unsure whether your claim is valid, seek advice before the window closes rather than after.
Companies purchasing residential property pay SDLT at higher rates, including a flat 17% rate on properties over £500,000. Refund opportunities for companies are more limited than for individuals and depend on the specific structure of the transaction. Group relief remains available where property is transferred between companies within the same corporate group. If you believe your company overpaid SDLT, a specialist review of the original return is the appropriate first step.
Inherited property is not subject to SDLT as no purchase transaction takes place. However, if you inherited a property and then purchased a new home while still owning the inherited property, you may have paid the higher rates surcharge on that purchase. Whether a refund is available depends on whether the inherited property counts as your main residence and whether you subsequently sold it within the 36-month window. Each case turns on its specific facts and timeline.
