How to Claim Back Stamp Duty on a Second Home

This page covers Stamp Duty Land Tax, the purchase tax for England and Northern Ireland. Scotland charges Land and Buildings Transaction Tax with its own Additional Dwelling Supplement, and Wales charges Land Transaction Tax with its own higher residential rates. Those are separate taxes with separate refund routes — see our comparison of the three regimes.

1. Am I eligible? The 3-year replacement rule

The higher rates for additional dwellings — what most people call the second-home surcharge — apply when you buy a residential property for £40,000 or more and, at the end of the day of purchase, it is not the only such property you own anywhere in the world. HMRC’s guidance puts the common case plainly: you pay the higher rates if you have not sold or given away your previous main home by the time you complete on the new one.

That is the position on completion day. It is not the final position. If you then sell or give away your previous main home within three years of buying the new one, HMRC says you “can apply for a refund” of the higher-rates element. This is the replacement-of-main-residence rule in paragraph 3 of Schedule 4ZA Finance Act 2003. Nothing about it is discretionary: meet the conditions and the money is yours.

What counts as your previous main residence

Two things have to be true. The property must have been your only or main residence at some point in the three years ending on the day you bought the new one, and you must have disposed of your whole interest in it. Selling a share while keeping a share does not open the claim.

Which property was your main residence is a question of fact rather than a choice you declare. HMRC looks at where you actually lived, and the evidence that supports it: council tax records, utility accounts, the electoral roll, where post was delivered, where you were registered with a GP. If you have owned two homes and lived across both, assemble that evidence before you claim rather than after HMRC asks.

2. How long you have to claim

Two separate clocks run, and people conflate them constantly.

The first is the sale deadline. Your previous main residence must normally be sold within three years of the effective date of the new purchase. Miss that and there is no claim at all, however quickly you then apply.

The second is the claim deadline. Where the previous home was sold on or after 29 October 2018, HMRC must receive your claim by whichever is later of: 12 months after the date of that sale, or 12 months after the filing date of the SDLT return for your new home. That is the wording in HMRC’s refund guidance, and it mirrors paragraph 8 of Schedule 4ZA, which allows the return to be amended within 12 months beginning with the effective date of the sale or, if later, the filing date for the return.

If your old home sold on or before 28 October 2018

An older and much shorter rule applies: HMRC must receive the claim within 3 months of the sale, or 12 months after the filing date of the SDLT return, whichever is later. This only matters now for very old transactions, but it is the reason some older articles quote a three-month deadline.

3. Divorce, probate, chain collapse and joint buyers

Most refused claims are ordinary situations that fall outside a rule the buyer did not know existed. These are the ones that come up most.

You bought before you managed to sell

This is the standard case and it is fine. You pay the higher rates on completion because you own two properties that day, then reclaim once the old home sells inside the three years. Paying the surcharge is not an error to be corrected — it is the correct tax on the day, later displaced by the sale.

The chain collapsed and the sale slipped

A collapsed chain does not extend the three years by itself. What matters is whether the sale still completes inside the window. If it will not, the only route is the exceptional-circumstances extension below. Practical detail is in our guide to stamp duty refunds after a chain collapse.

Sale delayed beyond three years by something outside your control

Paragraph 3(7B) of Schedule 4ZA lets HMRC extend the three-year window. HMRC’s manual at SDLTM09807 sets two tests: you were prevented from selling by exceptional circumstances that could not reasonably have been foreseen, and you sold as soon as you reasonably could once you were no longer prevented. Both must hold. HMRC says it is unlikely to allow an extension where the circumstances ended well before the three years ran out, or where you did not leave a reasonable amount of time to sell in the first place. The application must be made within 12 months of the sale.

Divorce or separation

Separating couples routinely end up owning two homes for longer than they intended. The rule does not bend for that, but the ordinary replacement route still works if the former main residence is disposed of inside three years — including where it is transferred to an ex-partner rather than sold on the open market, provided you dispose of your whole interest. Married couples and civil partners are treated as one unit for the higher rates: HMRC’s guidance states that if either of you individually would have to pay the higher rates, the higher rates apply to the whole transaction. Our guide to stamp duty on divorce and separation covers the property-transfer mechanics.

Inherited property and probate

This one is different in kind, and it is worth understanding why. An inherited share is not a refund route — it is a reason the surcharge may not have been due at all. Under paragraph 16 of Schedule 4ZA, explained at SDLTM09795, an interest inherited in the three years before your purchase is disregarded where your share — together with any held by your spouse or civil partner — is 50% or less. If that describes you and the surcharge was charged anyway, you are not making a replacement claim; you are correcting a return that was wrong. See our guide to stamp duty on inherited property.

Joint buyers where only one of you owned before

For joint purchasers, HMRC’s guidance is that if any one of you individually would have to pay the higher rates, the higher rates apply to the whole transaction. There is no apportionment: one buyer’s existing property taxes the entire purchase. The refund follows the same logic — the disposal of the previous main residence is what opens the claim.

Non-UK residents

The non-resident surcharge is a separate 2 percentage points on top, in force since 1 April 2021, and it has its own refund route with its own timetable. You can reclaim it if you are present in the UK for at least 183 days in any continuous 365-day period falling within the window that begins 364 days before the effective date and ends 365 days after it, and the claim can be made within two years of the effective date. It is entirely separate from the second-home surcharge: a non-resident buying an additional property can be due both refunds, claimed separately. See our non-resident surcharge guide.

4. How much you get back: a worked example

Take a £350,000 purchase completing after 1 April 2025, where you already owned a home and sold it eight months later. The higher rates are the standard residential rates plus 5 percentage points in every band.

Slice of the price	Standard	You paid
First £125,000	0% — £0	5% — £6,250
£125,001–£250,000	2% — £2,500	7% — £8,750
£250,001–£350,000	5% — £5,000	10% — £10,000
Total SDLT	£7,500	£25,000

Refund: £17,500

£25,000 paid, less the £7,500 that would have been due without the surcharge. That £17,500 is exactly 5% of £350,000 — which is the shortcut worth remembering: the refund is 5% of the price you paid (3% for completions before 31 October 2024). On a £250,000 flat it is £12,500; on a £600,000 house, £30,000.

One point of detail that catches people out. The rate rose from 3 to 5 percentage points for transactions with an effective date on or after 31 October 2024. Where contracts were exchanged before that date but completed on or after it, transitional rules mean the 3% rate can still apply. Reclaim what you actually paid, not what today’s rate would be — the figure is on your SDLT return.

5. How to claim it back, step by step

HMRC provides this claim for buyers to make themselves. You apply either online through the ‘Apply for a refund of the higher rates of Stamp Duty Land Tax’ service on GOV.UK, or by printing and posting form SDLT16 to the address shown on it. HMRC warns that you cannot save a part-completed form, so gather everything first.

1Find your UTRNThe SDLT unique transaction reference number is on the SDLT5 certificate issued when the return for your purchase was filed. Your conveyancer will hold it if you do not.
2Confirm both key datesThe effective date of the purchase that attracted the higher rates, and the effective date of the sale of your previous main residence. These drive both the 3-year test and the claim deadline.
3Work out the surcharge elementThe refund is the surcharge element of the tax paid: 5% of the chargeable consideration for purchases completing on or after 31 October 2024, or 3% before that date.
4Submit the claim to HMRCUse HMRC's online 'Apply for a refund of the higher rates of Stamp Duty Land Tax' service, or print and post form SDLT16 to the address on the form.
5Keep your evidenceRetain the SDLT5, both completion statements, and proof that the previous property was your main residence, in case HMRC checks the claim after paying it.
6Receive the repaymentHMRC says it will usually pay directly into the nominated bank account within 15 working days of receiving the claim.

What HMRC asks for

Your details, and the main buyer’s details
The property that attracted the higher rates: address, effective date of purchase, and the SDLT unique transaction reference number (UTRN)
Your previous main home: address, effective date of sale, and the name of the person who bought it
The amount of tax paid on the property that attracted the higher rates
The amount you are asking HMRC to repay
Bank account number and sort code of the person who should receive the payment

The UTRN is on the SDLT5 certificate produced when the return for your purchase was filed. If you cannot find it, your conveyancer will have it. An agent can submit on your behalf, but HMRC requires a covering letter and a signed authority from the buyer.

Evidence to keep

You are not generally asked to upload proof of residence with the claim, which is precisely why you should keep it. Hold on to the SDLT5, both completion statements, and the records showing the old property was your main home. Our SDLT refund documents checklist sets out what to assemble.

How long a second-home stamp duty refund takes

HMRC states that it “will usually make the payment directly into your bank account within 15 working days of receiving your claim”. Read the next sentence of HMRC’s guidance too, because it matters more than the timescale: to process refunds quickly, HMRC makes the payment without first checking eligibility. Money arriving is not HMRC agreeing with you. It can check afterwards, and if the claim was wrong you repay it in full along with any interest due.

If nothing has arrived well beyond 15 working days, chase it through HMRC’s Stamp Duty Land Tax enquiries line with your UTRN to hand. HMRC does not publish a target response time for SDLT correspondence in the way it does for other taxes, so we cannot tell you what “too long” officially is. Our guide on how long a stamp duty refund takes covers what to do when a claim goes quiet.

6. Why claims get rejected or clawed back

Because HMRC pays first and checks later, a refund landing in your account is not the end of the story. These are the failure modes worth designing your claim around.

The old property was not really your main residence. The most common challenge, and the hardest to fix after the fact. It is a question of where you actually lived, evidenced at the time.
The sale fell outside three years and no exceptional-circumstances application was made, or one was made that fails the “sold as soon as you reasonably could” test.
The claim missed the 12-month window. Nothing cures a late claim. Diarise the deadline the day your old home sells.
You disposed of part, not all, of your interest in the previous main residence.
The figures do not match the original return. The amount you say was paid must reconcile to the SDLT return HMRC holds against that UTRN.
An agent claimed without written authority. HMRC requires a signed letter of consent from the main buyer.

If HMRC does come back, that is not the end either — see what to do when HMRC rejects or queries a claim and our guide to HMRC clawback.

One thing we cannot tell you

Whether HMRC adds repayment interest to a second-home surcharge refund. HMRC’s published SDLT refund guidance is explicit that interest is due from you if a refund is later found to be wrong, but it does not state that interest is paid to you on a valid claim. We are not going to assert it either way. Treat the surcharge figure as the amount to expect, and anything else as a bonus.

7. Frequently asked questions

How do I claim back stamp duty on a second home?

You apply directly to HMRC using the 'Apply for a refund of the higher rates of Stamp Duty Land Tax' service on GOV.UK, either online or by posting form SDLT16. You need the address and effective date of the property that attracted the higher rates, its SDLT unique transaction reference number (UTRN), the effective date of sale and address of your previous main home plus the name of its buyer, the amount of tax paid, the amount you want repaid, and the bank details of the person receiving the payment. You do not need a solicitor or a claims firm to do this.

How long does a second-home stamp duty refund take?

HMRC states that it will usually make the payment directly into your bank account within 15 working days of receiving your claim. HMRC also says it makes the payment without first checking eligibility in order to process refunds quickly, so a payment arriving is not confirmation that your claim was correct — HMRC can check afterwards and reclaim it.

How long do I have to claim back the stamp duty surcharge?

For a previous main home sold on or after 29 October 2018, HMRC must receive your claim by whichever is later: 12 months after the date of that sale, or 12 months after the filing date of the SDLT return for your new home. The sale itself must normally have happened within 3 years of buying the new property.

Can I claim the surcharge back if I sold more than 3 years after buying?

Sometimes. Paragraph 3(7B) of Schedule 4ZA Finance Act 2003 lets HMRC extend the 3-year window where you were prevented from selling by exceptional circumstances that could not reasonably have been foreseen, and you then sold as soon as you reasonably could once that obstacle ended. It is not automatic and HMRC is unlikely to agree where the circumstances ended well before the 3 years ran out, or where you left too little time to sell in the first place. The application must be made within 12 months of the sale.

Do I need a solicitor to claim a stamp duty refund?

No. The claim is a form submitted by the buyer directly to HMRC, and HMRC provides it for buyers to use themselves. An agent can submit on your behalf but must include a signed letter of authority from you. Claims firms will handle it for a percentage of the refund, typically 25–40%.

How much is the second-home stamp duty surcharge?

For purchases completing on or after 31 October 2024 the higher rates are 5 percentage points above the standard residential rates, so the surcharge element is 5% of the purchase price. Before that date it was 3 percentage points. Where contracts were exchanged before 31 October 2024 but completed on or after it, transitional rules mean the 3% rate can still apply.

What counts as my previous main residence?

It must have been your only or main residence at some point in the 3 years ending on the date you bought the new property, and you must have disposed of your whole interest in it. Where you have owned more than one home, which one was your main residence is a question of fact, not of choice — HMRC looks at where you actually lived and the supporting evidence such as council tax, utility bills and electoral roll records.

Can I claim if my spouse owned the other property, not me?

Married couples and civil partners are treated as a single unit for the higher rates: if either of you would have to pay them, the whole transaction pays them. The corresponding point applies to the refund — the disposal of the previous main residence by either spouse or civil partner is what opens the claim, provided the other conditions are met.
