Stamp Duty on a Second Home: Can You Claim a Refund?
If you sold your main residence within 3 years, you may be owed thousands back.
Stamp Duty Land Tax (SDLT) is the property purchase tax for England and Northern Ireland. Scotland operates a separate regime — Land and Buildings Transaction Tax, with an Additional Dwelling Supplement (LBTT-ADS) — and Wales operates Land Transaction Tax (LTT) with its own higher residential rates. The rules, rates, and refund procedures on this page apply only to purchases in England and Northern Ireland.
What is the 5% second home surcharge?
The 5% surcharge is formally known as the Higher Rates for Additional Dwellings (HRAD). It applies on top of standard SDLT rates when someone already owning a residential property buys an additional one in England or Northern Ireland. It applies whether the new property is a second home, a buy-to-let, or a holiday let, and it applies whether the property already owned is in the UK or anywhere else in the world.
Current rate and history
HRAD was introduced on 1 April 2016 at 3 percentage points on top of the standard residential SDLT bands. It remained at 3% for over eight years. It rose to 5% with effect from 31 October 2024, as announced at the Autumn Budget 2024. The current rate on the gov.uk SDLT rates page is 5%, and applies to any additional residential property completing on or after 31 October 2024.
The surcharge is calculated on the entire chargeable consideration and added to every standard SDLT band — it is not a separate band of its own. The statutory framework sits in Schedule 4ZA, Finance Act 2003, with HMRC’s practical guidance at SDLTM09730.
Who pays it
HRAD applies where four statutory tests, set out in Schedule 4ZA paragraph 3, are all met. The chargeable consideration is at least £40,000; the new property is not subject to a lease with more than 21 years to run; the buyer (or any joint buyer) already holds a major interest in another dwelling worth at least £40,000; and the new property is not a replacement for the buyer's only or main residence. If any one of those four conditions fails, the surcharge doesn't apply.
Married couples and civil partners living together are treated as a single buying unit. If one partner already owns a dwelling, the other partner's purchase is caught by HRAD even when bought in their sole name. Unmarried joint buyers are also caught: if any one of them already owns another dwelling, HRAD applies to the entire chargeable consideration, not just that buyer's share.
Worked example
Here's what a typical surcharge refund looks like on a £400,000 second home at current rates:
| Purchase price | £400,000 |
| Standard SDLT | £10,000 |
| 5% HRAD surcharge | £20,000 |
| Total paid at completion | £30,000 |
| Refund if previous main residence sold within 3 years | £20,000 |
Calculated at current standard residential SDLT rates plus the 5% HRAD surcharge. The refund covers the HRAD portion only — standard SDLT remains payable. Use our SDLT calculator for your exact figures, or our refund estimator to check what you may be owed.
Surcharge refund at a glance
Because HRAD is a flat 5% of the entire chargeable consideration, the reclaimable amount scales directly with the purchase price. The refund is the surcharge in full — the standard SDLT below stays payable.
| Purchase price | 5% HRAD surcharge paid | Refund if previous main residence sold within 3 years |
|---|---|---|
| £300,000 | £15,000 | £15,000 |
| £500,000 | £25,000 | £25,000 |
| £750,000 | £37,500 | £37,500 |
| £1,000,000 | £50,000 | £50,000 |
Surcharge figures are 5% of the purchase price at the current HRAD rate (since 31 October 2024), per the gov.uk SDLT rates page. Purchases completing between 1 April 2016 and 30 October 2024 paid the surcharge at 3%, so the reclaimable amount is correspondingly lower.
The 3-year replacement rule
If you buy a new main home before selling your existing one, you'll pay HRAD at completion because, on the day, you own two dwellings. Schedule 4ZA paragraph 8(3) allows you to reclaim the surcharge if you sell the previous main residence within 3 years of the new purchase. This is known as the replacement-of-main-residence relief.
The claim window itself was originally short — only 3 months from the sale of the previous home. Section 43 of the Finance Act 2019 extended this window to 12 months from 29 October 2018. The claim must be made within 12 months of the sale of the old property, or 12 months after the filing date of the SDLT return for the new property — whichever is later.
HMRC's guidance on what counts as a “main residence” for these purposes is at SDLTM09812. The test is one of actual residence, not formal designation: where you actually lived, slept, and treated as home — supported by council tax, utility, and electoral roll evidence.
Exceptional circumstances
Paragraph 3(7B) of Schedule 4ZA gives HMRC discretion to extend the 3-year window where the sale was delayed by circumstances beyond the buyer's control. HMRC's published guidance on what qualifies is at SDLTM09807. Examples HMRC has historically accepted include pandemic-era restrictions on viewings and exchanges, fire or flood damage to the previous home that delayed marketing, and protracted chain collapses that the buyer could not reasonably have foreseen or avoided. Ordinary market conditions — slow sale, falling prices, declined offers — are not exceptional.
Do you qualify for a refund?
Use this as a self-check. You should be able to answer “yes” to each of the following before submitting a claim:
- •You paid the HRAD surcharge. Your SDLT return or completion statement shows the additional-property surcharge was applied (5% from 31 October 2024; 3% before).
- •You sold your previous main residence within 3 years. The sale of the previous home completed within 3 years of completing the new purchase.
- •You actually lived in the previous property as your main home. Council tax, utility bills, and electoral roll entries in your name at that address support the claim.
- •The new property is or was your only or main residence after completion. A buy-to-let or holiday let purchase does not qualify for the replacement relief — those purchases simply pay HRAD outright.
- •Your claim window is still open. 12 months from the sale of the previous home, or 12 months from the SDLT return filing date for the new property — whichever is later.
- •You have the supporting documents. SDLT5 / UTRN, completion statements for both transactions, and main-residence evidence at the previous address. See our documents checklist for the full list.
How to claim the surcharge back
The refund process has six steps. HMRC now publishes an online refund service, which is the preferred route for most claims; postal form SDLT16 remains available as an alternative.
- 1Gather your documents. Locate your SDLT5 (which carries the UTRN), the completion statement for the new purchase, and evidence of the sale of the previous main residence. Our documents checklist walks through each item.
- 2Confirm the sale date of the previous main residence. The 12-month claim clock runs from this date, or from the SDLT return filing date for the new property — whichever is later.
- 3Complete the HMRC refund form. Use HMRC's online “Apply for a refund of the higher rates of Stamp Duty Land Tax” service, or post form SDLT16 if you prefer paper.
- 4Submit with supporting evidence. Attach main-residence evidence (council tax, utilities, electoral roll) alongside the SDLT5 and sale documentation. Strong evidence at submission reduces the likelihood of HMRC opening a compliance check.
- 5Wait for HMRC processing. Straightforward claims are typically processed within 15–20 working days. Complex or queried claims can take six to twelve weeks.
- 6Receive the refund. HMRC pays the refund directly to the bank account on the original SDLT return. Repayment interest under Schedule 54 of the Finance Act 2009 may also be paid.

Common edge cases and gotchas
HRAD is one of the most-litigated areas of SDLT. The cases below come up regularly and often catch buyers (and their solicitors) by surprise.
Partner already owns a property
Married couples and civil partners living together are treated as a single buying unit for HRAD purposes. If your spouse owns a flat from before you met, your purchase of a marital home is caught by HRAD — even though, on paper, this is your first property and you are buying in your sole name. The refund route is the same: if the spouse's prior property is sold within 3 years, the HRAD paid on the new purchase is reclaimable.
Joint purchase with a parent or child
Unmarried joint buyers — most often a parent helping a child onto the housing ladder — are caught even more cleanly than married couples. If any one joint buyer already owns a dwelling, HRAD applies to the entire chargeable consideration, not just to that buyer's share. A common trap: a parent who owns their own home is named on the title as a co-borrower to help with mortgage affordability. The child's first purchase then falls within HRAD on the full price.
First-time buyer × HRAD
First-time buyer relief under Schedule 6ZA, Finance Act 2003 requires every purchaser to be a first-time buyer. If you buy jointly with a partner who has previously owned a dwelling, FTB relief is lost on the entire purchase. The HRAD surcharge then applies under Schedule 4ZA for the same reason — one of the joint buyers already owns another dwelling. Joint purchases with a non-FTB partner are one of the most expensive SDLT mistakes a first-time buyer can make.
Non-resident buyers
Since 1 April 2021, non-UK residents pay a further 2 percentage points on top of standard SDLT bands — the Non-Resident SDLT surcharge (NRSDLT), legislated by Finance Act 2021. The two surcharges stack: a non-resident buyer who already owns another dwelling pays standard SDLT + 5% HRAD + 2% NRSDLT. HMRC's residence test and the rates are set out at gov.uk/guidance/rates-of-stamp-duty-land-tax-for-non-uk-residents. NRSDLT also has its own refund route if the buyer subsequently becomes UK-resident under the day-count test.
Annexes and Multiple Dwellings Relief
Where a property has a self-contained annexe, the purchase may historically have qualified for Multiple Dwellings Relief, reducing the effective SDLT charge. MDR was abolished for transactions with an effective date on or after 1 June 2024, but a transitional carve-out preserves MDR for contracts entered into on or before 6 March 2024, regardless of when completion takes place. Annexe purchases falling within the carve-out should still be assessed for MDR alongside the HRAD position — see our Multiple Dwellings Relief guide.
Didn't sell within 3 years
If the sale of the previous main residence completed more than 3 years after the new purchase, the ordinary replacement-relief route is closed. The exceptional-circumstances extension under Schedule 4ZA paragraph 3(7B) (see above) may still apply where the delay was beyond the buyer's control. Practical guidance on late sales and the evidence HMRC looks for is in our blog post: Sold Your Home Late? Here's What to Do. The surcharge is one of the routes our refund tool screens — see if you qualify in 90 seconds.
One further category worth flagging: if the new property was uninhabitable at the point of completion, the question is not whether HRAD applies but whether SDLT residential rates apply at all. The Mudan and Bewley line of authority addresses this. For that test, see our separate guide at uninhabitable property stamp duty; we don't expand the case law here.
What if HMRC rejects your claim?
HRAD refunds are mostly paid without query, but HMRC does open compliance checks where evidence of main-residence status is thin, where the chain of dates doesn't cleanly meet the 3-year window, or where one of the four statutory conditions looks borderline. A rejection is not necessarily the end — most queries can be resolved with additional evidence, and formal appeal routes exist where they can't. Our guide at what to do if HMRC rejects your stamp duty claim walks through the response options.
Frequently asked questions
How long do I have to claim the surcharge refund?
You must apply within 12 months of the sale of your previous main residence, or 12 months after the filing date of the SDLT return for the new property — whichever is later. The sale must happen within 3 years of the new purchase.
What if I didn't sell my previous home — can I still claim?
The surcharge refund specifically requires the sale of your previous main residence. If you still own both properties and neither has been sold, you cannot reclaim the surcharge. However, you may still be able to claim a chattel-based refund on the overpaid SDLT.
How do I claim the 5% surcharge back from HMRC?
HMRC's preferred route since August 2024 is the online "Apply for a refund of the higher rates of Stamp Duty Land Tax" service on gov.uk; postal form SDLT16 is the alternative. You'll need your SDLT reference number from the original return, the completion date of the sale of your previous main residence, and evidence that the previous property was your main home. HMRC typically processes straightforward refund claims within 15–20 working days, though complex cases can take longer.
Can I claim stamp duty back if my partner already owns a home?
If your partner (married or civil partner) already owns a property, the surcharge applies to your purchase even if it's your first property. However, if your partner sells their existing property within 3 years of your joint purchase, you can reclaim the surcharge.
Can I get the surcharge back if I sold more than 3 years after buying?
In limited cases, yes. Schedule 4ZA paragraph 3(7B) gives HMRC discretion to extend the 3-year window where the sale was delayed by exceptional circumstances beyond the buyer's control — pandemic restrictions, fire or flood damage, or extreme chain breakdowns are commonly cited examples. The extension is not automatic; you must apply and explain why the delay was unavoidable.
Does the 5% surcharge apply if I'm buying as a non-resident?
Yes, and the Non-Resident SDLT surcharge (NRSDLT) stacks on top. Since 1 April 2021, non-UK residents pay an additional 2 percentage points on residential purchases in England and Northern Ireland. A non-resident buying a second home therefore pays standard SDLT + 5% HRAD + 2% NRSDLT.
Does HMRC pay interest on the refund?
HMRC pays repayment interest on overpaid SDLT under Schedule 54 of the Finance Act 2009. Interest runs from the date of the original SDLT payment until the date HMRC repays. The current repayment interest rate is published on gov.uk and changes periodically in line with Bank of England base rate movements.
Are first-time buyers exempt from the 5% surcharge when buying jointly with a partner who already owns a property?
No. Two things happen in this scenario, both adverse. First-time buyer relief under Schedule 6ZA Finance Act 2003 requires every purchaser to be a first-time buyer; if your partner has previously owned a dwelling, relief is lost on the entire purchase. The HRAD surcharge then applies under Schedule 4ZA because one of the joint buyers already owns another dwelling. Joint purchases with a non-first-time-buyer partner are one of the most common SDLT traps.
