Stamp Duty Refund: Can You Claim It Back?

Stamp Duty Refunds in Numbers

The second-home surcharge refund is the one most buyers claim, and HMRC's own figures show how common it is. In 2024-25 HMRC refunded £501 million of the higher rates on 26,700 purchases in England and Northern Ireland. That works out at about £18,800 per refund (our calculation from HMRC's rounded figures).

Source: HMRC Quarterly Stamp Duty Land Tax Statistics, Table 3a. Counts are rounded to the nearest 100 and amounts to the nearest £1 million. HMRC changed its method from 2022-23, so earlier years are not directly comparable. 2016-17 and 2017-18 also include Wales, which moved to Land Transaction Tax in April 2018. The quarterly publication ended in April 2025. The same series continues in HMRC's Annual Stamp Tax Statistics (March 2026, Table 2f), whose latest figures also run to March 2025.

Can You Claim Stamp Duty Back?

Yes, in the situations HMRC lists. According to GOV.UK, you may get a refund if:

• you paid the higher rates on a new main home and have since sold your previous main home
• you paid the non-UK resident surcharge and now count as UK resident for SDLT
• you were entitled to a relief or exemption you did not claim on the original return
• you paid residential rates when the non-residential rates applied
• you made a mistake working out the tax on the original return
• you worked out the right tax but paid HMRC too much by mistake

Refunds are never automatic. You have to claim, and each route has its own deadline.

Common situations, answered

If all of these apply, the refund is the surcharge itself: 5% of the price, or 3% if you exchanged contracts before 31 October 2024. On a £350,000 home bought today that is £17,500. Check your own figure with the stamp duty refund calculator.

Refund Types: Detailed Eligibility & Time Limits

The five refund types have very different rules and deadlines. Below is the detailed eligibility for each, with cross-links to the dedicated guides where the topic gets deeper treatment.

1. Second-Home Surcharge Refund (most common)

Most people call this the second home stamp duty refund. If you bought a new home while still owning your previous main residence, you paid the 5% surcharge (8% ADS in Scotland, the higher residential bands in Wales). You can claim the surcharge back once you sell the old home, as long as the sale is within 3 years and your claim is in time. It is only available when the home you sell was your main residence. Selling a buy-to-let or holiday home does not qualify. See the refund deadlines for the timeline and the replacement of main residence rules for the underlying law.

2. Non-Resident Surcharge Refund

If you were treated as a non-UK resident when you bought a property and paid the 2% non-resident surcharge, you can reclaim it if you meet the UK residence test for this surcharge. That test requires at least 183 days in the UK in any continuous 365-day period that begins no more than 364 days before the effective date of the transaction and ends no more than 365 days after it, so the qualifying window spans time on both sides of the purchase and does not simply start on the purchase date. HMRC counts arrival and departure days. The claim must be made within 2 years of the effective date of the transaction (normally the completion date), not 2 years from the date you became UK resident. Keep flight records, hotel bookings and utility bills as evidence.

3. Uninhabitable Property Refund

A building that is not suitable for use as a dwelling is taxed at the non-residential rates (0% up to £150,000, 2% to £250,000, 5% above), which can be much lower. The bar is high. In Mudan v HMRC (Court of Appeal, 2025) the court confirmed that a home needing repair is still residential if it keeps the fundamental characteristics of a dwelling, and that "suitable for use as a dwelling" does not mean ready to move into. Previous use as a home counts against the claim. A new boiler, rewiring or damp proofing is not enough. See the uninhabitable property stamp duty refund guide for the cases that have won and lost, and HMRC's example of what a failed claim costs.

4. Overpayment Refund

You can claim a refund where you overpaid SDLT because of a calculation error, the wrong rates, or a relief you did not claim, such as first-time buyer relief or Multiple Dwellings Relief (transactions before 1 June 2024). Within 12 months of the filing date you amend the return. After that, overpayment relief under Schedule 10 paragraph 34 FA 2003 can cover a calculation error or the wrong rates, up to four years after the effective date of the transaction (paragraph 34B(1)). It does not rescue a missed relief: Case A in paragraph 34A excludes an overpayment caused by failing to make a claim, so a relief not claimed within the amendment window is generally lost. If you paid SDLT on a contract that was substantially performed and it was later rescinded, annulled or not carried out, the tax is repayable to that extent by amending the return made for the contract (FA 2003 s44(9)). See the refund deadlines for what happens once a deadline has passed.

5. Chattels Not Deducted From the Price

SDLT is charged on land and buildings, not on moveable items. Under FA 2003 Schedule 4 paragraph 4 the price must be split on a just and reasonable basis, and HMRC's manual (SDLTM04010) accepts carpets, curtains and blinds, free-standing furniture, white goods that are not fully integrated, removable electric and gas fires, and light shades as chattels. Fitted kitchens, Agas, bathroom suites, central heating and alarm systems are not.

The catch is evidence. HMRC says that in most cases no apportionment for chattels is appropriate, and that a deduction only stands if you can show contemporaneous evidence from the conveyancing that the chattels were separately negotiated, for example expressly identified and priced in the sale contract. Its words: "Simply showing that there were some chattels in the property when it was sold would not be considered sufficient evidence." Values must be second-hand open market values, not what the items cost new. Because the saving is only the tax on that value, a genuine chattels refund is usually small: £2,000 of chattels on a purchase where the top slice is taxed at 5% saves £100.

6. Special Circumstances

• Divorce or separation: Property transfers made in connection with divorce, dissolution, annulment or judicial separation are SDLT-exempt under FA 2003 Schedule 3 paragraph 3 (or 3A for civil partners), whether made under a court order or by an agreement in contemplation of those proceedings. If SDLT was paid in error, a refund applies. See the divorce property transfer guide.
• Defective title: If the purchase is unwound due to title defects discovered after completion, SDLT becomes refundable.
• Compulsory purchase: If a property is later compulsorily purchased by a public authority, the original SDLT may be reclaimable under compulsory purchase relief.

Refund Deadlines and What If You Miss Them

Two separate deadlines govern the higher-rate refund, and they work differently. Both are conditions of entitlement set by statute (Schedule 4ZA Finance Act 2003), not penalty deadlines, so the “reasonable excuse” rules that can excuse a late filing penalty do not apply here. In England and Northern Ireland, apart from the narrow exceptional-circumstances rule below, miss either deadline and the right to the refund is lost.

Took longer than 3 years to sell? Exceptional circumstances

GOV.UK allows a late refund if you bought the new home on or after 1 January 2017, exceptional circumstances stopped you selling the old one, and you have now sold it without further delay once the obstacle ended. HMRC means events that usually affect large groups of people, such as government restrictions or action by a public authority that prevents the sale. Not finding a buyer at your price, delays agreeing terms and a chain collapsing do not count. You apply by letter to BT Stamp Duty Land Tax, HM Revenue and Customs, BX9 1HD, explaining why you could not sell within 3 years, and the law requires the application within 12 months of the sale (FA 2003 Schedule 4ZA paragraph 3(7B)).

If You Think You Have Missed the Deadline

Do not assume the refund is gone without checking two things first:

• Verify the exact dates. Get the completion statements for both properties. Off-by-one errors and using exchange dates instead of completion dates are common, and you may be inside the window after all.
• Check for a separate overpayment. If the SDLT was wrong for another reason (a calculation error or the wrong rates), overpayment relief may apply on its own timeline, subject to the four-year limit and the exclusions set out below.

If a solicitor handled both your purchase and your later sale and failed to flag the refund, causing you to miss the deadline, the lost refund may be recoverable as a professional negligence claim against them rather than from HMRC. The stakes are usually tens of thousands of pounds, so specialist SDLT advice is worthwhile. Check the exact figure with the stamp duty refund calculator.

Documents You Will Need

Having all documents ready before you start your claim will significantly speed up processing. Missing information is the single most common cause of delayed or rejected claims.

How to Claim: Online or by Post

For the second-home surcharge refund, HMRC has an online form and a paper form, SDLT16. Other refunds (a missed relief, the wrong rates, a calculation error) are claimed by amending the return within 12 months of the filing date, or by a written overpayment relief claim after that. HMRC does not publish different processing times for online and postal claims. Its stated time is the same: usually within 15 working days of receiving the claim.

Step-by-Step Claim Process

Follow these steps to submit your higher rate refund claim. For the amendment process (overpayments), see the SDLT return amendment guide.

What Your Solicitor Does

Many solicitors routinely handle stamp duty refund claims on behalf of their clients, particularly conveyancers who handled both the purchase and the subsequent sale. However, their involvement is not automatic and there is often an additional charge for this service.

How Long Does a Stamp Duty Refund Take?

Usually within 15 working days of HMRC receiving your claim. That is HMRC's own statement on GOV.UK: it will usually pay directly into your bank account within 15 working days. The clock starts when HMRC receives the claim, not when you post it, and it counts working days only, so three calendar weeks is a fair expectation. HMRC does not publish how often it meets that, or separate times for online and postal claims.

What slows a refund down

• HMRC needs more information. It writes by post, so the delay includes the time letters take each way.
• A missing detail on an amendment. For a postal amendment, GOV.UK warns that if you do not send all the information and documents, HMRC may reject it as invalid.
• Not every buyer is on the claim. All purchasers must be included.
• Wrong bank details. The payment goes where the form says.

What Happens After Submission

HMRC pays first and checks later. In its own words, "to process refunds quickly, we will make the payment without checking eligibility", so a payment is not a sign that the claim has been accepted. HMRC has up to 9 months to open a compliance check on your amended return or claim.

If HMRC Rejects Your Claim: Review and Appeals

HMRC must give reasons for rejecting a refund claim. The most common are a missed deadline, HMRC not accepting that the property you sold was your main residence, insufficient evidence, or an administrative error such as a wrong UTRN. Read the rejection letter carefully: it sets out the reason and your appeal rights, including the deadline to request a review (usually 30 days).

Step 1: Ask for an internal review (free)

An internal review is carried out by an HMRC officer who was not involved in the original decision. It is free and you should always use it before going to a tribunal. Request it in writing within 30 days of the rejection, quote your UTRN and case reference, set out why the decision is wrong, and attach supporting evidence. HMRC normally completes the review within 45 days and can uphold, vary, or cancel the original decision.

Step 2: Appeal to the First-tier Tax Tribunal

If the review upholds the rejection, you have 30 days to appeal to the First-tier Tax Tribunal (Tax Chamber), an independent court that is not part of HMRC. Most SDLT refund cases fall in the basic track, which usually carries no filing fee and little costs risk. The Tribunal can decide factual disputes (such as dates or main residence status) but it cannot override a clear statutory deadline.

How to Track Your Claim

HMRC does not provide an online tracking system for stamp duty refund claims in the same way as self-assessment refunds. You can check the status by:

• Logging into your HMRC online account and checking the SDLT section
• Contacting HMRC's SDLT helpline (0300 200 3510) and quoting your UTRN and submission reference
• Asking your solicitor or agent if they submitted on your behalf

HMRC's stated time is 15 working days from receipt. If that has passed with no payment and no letter, it is reasonable to follow up. Allow extra time for postage if you sent SDLT16 by post.

Rogue Repayment Agents: HMRC's Warning

On 31 July 2025 HMRC issued a public warning about agents who cold-approach recent buyers offering to reclaim SDLT on a "no win, no fee" basis. The most common pitch is that a property was uninhabitable at the point of purchase and should therefore have been taxed at non-residential rates. HMRC's position is that this argument almost always fails, and the buyer, not the agent, carries the liability when it does.

The law is firmly against that pitch. In Mudan & Anor v HMRC [2025] EWCA Civ 799, the Court of Appeal confirmed that a dwelling in need of repair is still chargeable at residential rates, and that a repayment claim resting on a property's condition alone will not succeed. Being suitable for use as a dwelling is not the same as being ready for immediate occupation. The tests the tribunal applied were whether the building retains the fundamental characteristics of a dwelling, whether it is structurally sound, and whether it was previously used as a dwelling.

One case has since gone the other way on its facts. In Oakwood Great Oak Ltd v HMRC [2026] UKFTT 01138 (TC), released 5 August 2026, the First-tier Tribunal allowed an appeal where a house had stood empty for three to four years with substantial structural defects and asbestos throughout that made occupation unsafe. That is not a change in the law, and a First-tier decision binds nobody. It shows that the argument can still be won, but only on genuinely extreme facts, and it is the opposite of the "your house needed work, claim a refund" pitch. See the uninhabitable property SDLT guide for what the tribunal actually weighed.

Refund firms must now be registered with HMRC

Since 18 May 2026, anyone paid to deal with HMRC about someone else's tax affairs has had to register with HMRC as a tax adviser, through an agent services account. HMRC counts sending claims as dealing with it, so a firm you pay to submit a stamp duty refund claim for you is covered. For most firms the window to apply ran from 18 May to 18 August 2026. Firms that already held a Self Assessment or Corporation Tax agent code have until 18 November 2026.

A firm that keeps dealing with HMRC while unregistered first gets a formal compliance notice, then a £5,000 penalty for each further interaction. HMRC can ban repeat offenders and publish their names. Two cautions, though. HMRC says registration “is not a form of regulation and does not reflect your competency”, so a registered firm can still file a claim that fails. And if it does, the liability is still yours.

Warning signs

• An unsolicited letter, call or email shortly after your purchase completes
• A "no win, no fee" offer with a percentage fee, commonly around 30%
• An argument that your property was uninhabitable, derelict or in disrepair and so is non-residential
• A claim that the work is risk-free, or any reluctance to explain who is liable if HMRC rejects it
• Pressure to sign a deed of assignment giving the agent control of your repayment
• A firm that will not confirm in writing that it is registered with HMRC as a tax adviser

None of this means valid refunds are rare. The stamp duty refund calculator will tell you whether you have a genuine claim, and the step-by-step process above shows how to file it yourself. Where a legitimate claim exists, the most common ground is a replacement of main residence within 36 months, not the condition of the property.
